The generator-coordinate method is a flexible and powerful reformulation of the variational principle. Here we show that by introducing a generator coordinate in the Kohn-Sham equation of density-functional theory, excitation energies can be obtained from ground-state density functionals. As a viability test, the method is applied to ground-state energies and various types of excited-state energies of atoms and ions from the He and the Li isoelectronic series. Results are compared to a variety of alternative DFT-based approaches to excited states, in particular time-dependent density-functional theory with exact and approximate potentials.

The exact exchange-correlation (XC) potential in time-dependent density-functional theory (TDDFT) is known to develop steps and discontinuities upon change of the particle number in spatially confined regions or isolated subsystems. We demonstrate that the self-interaction corrected adiabatic local-density approximation for the XC potential has this property, using the example of electron loss of a model quantum well system. We then study the influence of the XC potential discontinuity in a real-time simulation of a dissociation process of an asymmetric double quantum well system, and show that it dramatically affects the population of the resulting isolated single quantum wells. This indicates the importance of a proper account of the discontinuities in TDDFT descriptions of ionization, dissociation or charge transfer processes.

Purpose Patients with chronic myelogenous leukemia in accelerated phase (CML-AP) that is resistant or intolerant to imatinib have limited therapeutic options. Dasatinib, a potent inhibitor of BCR-ABL and SRC-family kinases, has efficacy in patients with CML-AP who have experienced treatment failure with imatinib. We now report follow-up data from the full patient cohort of 174 patients enrolled onto a phase II trial to provide a more complete assessment of the efficacy and safety of dasatinib in this population. Patients and Methods Patients with imatinib-resistant (n = 161) or -intolerant (n = 13) CML-AP received dasatinib 70 mg orally twice daily. Results At a median follow-up of 14.1 months (treatment duration, 0.1 to 21.7 months), major and complete hematologic responses were attained by 64% and 45% of patients, respectively, and major and complete cytogenetic responses were achieved in 39% and 32% of patients, respectively. Responses were achieved irrespective of imatinib status (resistant or intolerant), prior stem-cell transplantation, or the presence of prior BCR-ABL mutation. The 12-month progression-free survival and overall survival rates were 66% and 82%, respectively. Dasatinib was generally well tolerated; the most frequent nonhematologic severe treatment-related adverse event was diarrhea (52%; grade 3 to 4, 8%). Cytopenias were common, including grade 3 to 4 neutropenia (76%) and thrombocytopenia (82%). Pleural effusion occurred in 27% of patients (grade 3 to 4, 5%). Conclusion Dasatinib is effective in patients with CML-AP after imatinib treatment failure.

Journal of clinical oncology; ISSN 0732-183X; Etats-Unis; Da. 2009; Vol. 27; No. 21; Pp. 3472-3479; Bibl. 30 ref.AnglaisPurpose Patients with chronic myelogenous leukemia in accelerated phase (CML-AP) that is resistant or intolerant to imatinib have limited therapeutic options. Dasatinib, a potent inhibitor of BCR-ABL and SRC-family kinases, has efficacy in patients with CML-AP who have experienced treatment failure with imatinib. We now report follow-up data from the full patient cohort of 174 patients enrolled onto a phase II trial to provide a more complete assessment of the efficacy and safety of dasatinib in this population. Patients and Methods Patients with imatinib-resistant (n = 161) or -intolerant (n = 13) CML-AP received dasatinib 70 mg orally twice daily. Results At a median follow-up of 14.1 months (treatment duration, 0.1 to 21.7 months), major and complete hematologic responses were attained by 64% and 45% of patients, respectively, and major and complete cytogenetic responses were achieved in 39% and 32% of patients, respectively. Responses were achieved irrespective of imatinib status (resistant or intolerant), prior stem-cell transplantation, or the presence of prior BCR-ABL mutation. The 12-month progression-free survival and overall survival rates were 66% and 82%, respectively. Dasatinib was generally well tolerated; the most frequent nonhematologic severe treatment-related adverse event was diarrhea (52%; grade 3 to 4, 8%). Cytopenias were common, including grade 3 to 4 neutropenia (76%) and thrombocytopenia (82%). Pleural effusion occurred in 27% of patients (grade 3 to 4, 5%). Conclusion Dasatinib is effective in patients with CML-AP after imatinib treatment failure.002B04; 002B19BDasatinib; Anticancéreux; Traitement; Imatinib; Leucémie myéloïde chronique; Protein-tyrosine kinase; Inhibiteur enzyme; Essai clinique; CancérologieTransferases; Enzyme; Inhibiteur de la tyrosine kinase; Inhibiteur multikinase; Hémopathie maligne; Cancer; Syndrome myéloprolifératifDasatinib; Antineoplastic agent; Treatment; Imatinib; Chronic myelogenous leukemia; Protein-tyrosine kinase; Enzyme inhibitor; Clinical trial; CancerologyTransferases; Enzyme; Tyrosine kinase inhibitor; Multikinase inhibitor; Malignant hemopathy; Cancer; Myeloproliferative syndromeDasatinib; Anticanceroso; Tratamiento; Imatinib; Leucemia mieloidea crónica; Protein-tyrosine kinase; Inhibidor enzima; Ensayo clínico; CancerologíaINIST-20094.35400018751942012009-0326540

Traditional stock assessment models were used to describe the current status of Lutjanus analis, L. chrysurus, L. jocu, L synagris, and L. vivanus stocks off the coast of Northeast Brazil. The yield per recruit model, cohort analysis models (length-based cohort analysis (LCA), pseudo-cohort virtual population analysis (VPA), and real cohort VPA), and Thompson and Bell predictive model were used. The results showed LCA accumulates biases from pseudo-cohort VPA along with a high degree of sensitivity ofgrowth parameters, whose determination is problematic and may not be adequate for many other reef species. Although the real cohort VPA based on short time series may also be limited, this method was determined to be the most appropriate within the traditional methods applied for the assessment of reef fish. However, the VPA model heavily depends on the accuracy of landing data and discards estimation and estimated natural mortality (M), so caution should be applied when using such models. The conservative fishing mortality index F0.1 was found to be the most adapted index when the uncertainty of parameter estimation and model limitations were considered. Consequently, a drastic reduction of 80-90% of the current fishing effort is recommended. Despite the VPA and Thompson and Bell model limitations, these models can provide insight into species/fishery dynamics and can also be utilised to analyse the effects of changes in fishing level on catches. In addition, the trends presented in this study are confirmed in a companion paper using more complex models.

This study investigates the exploitation of Lutjanus analis, Lutjanus chrysurus, Lutjanus jocu and Lutjanus synagris from multiple gear types in Northeast Brazil using models allowing for technological interactions. The spatial distribution of species and fleets have played an important role in the Northeastern Brazilian artisanal fishery. The results of a predictive model by Thompson and Bell, along with a catch-at-age model, clearly showed that different fleets had distinct effects on snapper stocks. The fishery mortality (F) from small-scale fleets ('Jangada' and 'Paquete') was higher for coastal species such as L. synagris that are typically found in these areas. Conversely, L. jocu, that inhabits deeper waters, was most affected by motorised and sailing boats. Snappers were exploited differently at each of their life history stages. 'Paquetes' mainly exploited juveniles, whereas boats caught larger individuals farther from the coast. As a consequence, effort control through fleet regulation seems to be much more applicable in a tropical context than traditional catch control. Further modelling studies and management options relevant to the Northeast Brazil fishery are discussed.

A series of silica-based materials were employed as sorbents within solid-phase microextraction vials. The aim of the study was to evaluate the effect of an additional phase on the distribution of the volatile and less volatile analytes. The adsorption of six probe molecules, namely isoamyl acetate, ethyl hexanoate (ethyl caproate), phenylethyl alcohol, ethyl octanoate (ethyl caprilate), 2-phenylethyl acetate, and ethyl decanoate, was monitored by detecting the desorbed amount on a DVD-CAR-PDMS fiber from Pilsen beer. The microextraction process involved the presence of different silica-based phases produced via different methods: xerogel produced by hydrolytic and non-hydrolytic routes, aerogel, pyrogenic, and precipitated silica. The resulting data are discussed in correlation with sorbent texture properties (specific area and pore diameter). The modification of silica with alkyl groups also affects the preconcentrated amount of the target molecules in the headspace. The presence of sorbents was shown to affect the analyte signal more than the addition of NaCl or the use of ultrasound.

Background Minimally invasive surgery (MIS) for late-presenting congenital diaphragmatic hernia (CDH) has been described previously, but few neonatal cases of CDH have been reported. This study aimed to report the multicenter experience of these rare cases and to compare the laparoscopic and thoracoscopic approaches. Methods Using MIS procedures, 30 patients (16 boys and 14 girls) from nine centers underwent surgery for CDH within the first month of life, 26 before day 5. Only one patient had associated malformations. There were 10 pre-term patients (32-36 weeks of gestational age). Their weight at birth ranged from 1,800 to 3,800 g, with three patients weighing less than 2,600 g. Of the 30 patients, 18 were intubated at birth. Results The MIS procedures were performed in 18 cases by a thoracoscopic approach and in 12 cases by a laparoscopic approach. No severe complication was observed. For 20 patients, reduction of the intrathoracic contents was achieved easily with 15 thoracoscopies and 5 laparoscopies. In six cases, the reduction was difficult, proving to be impossible for the four remaining patients: one treated with thoracoscopy and three with laparoscopy. The reasons for the inability to reduce the thoracic contents were difficulty of liver mobilization (1 left CDH and 2 right CDH) and the presence of a dilated stomach in the thorax. Reductions were easier for cases of wide diaphragmatic defects using thoracoscopy. There were 10 conversions (5 laparoscopies and 5 thoracoscopies). The reported reasons for conversion were inability to reduce (n = 4), need for a patch (n = 5), lack of adequate vision (n = 4), narrow working space (n = 1), associated bowel malrotation (n = 1), and an anesthetic problem (n = 1). Five defects were too large for direct closure and had to be closed with a patch. Four required conversion, with one performed through video-assisted thoracic surgery. The recurrences were detected after two primer thoracoscopic closures, one of which was managed by successful reoperation using thoracoscopy. Conclusions In the neonatal period, CDH can be safely closed using MIS procedures. The overall success rate in this study was 67%. The indication for MIS is not related to weeks of gestational age, to weight at birth (if >2,600 g), or to the extent of the immediate neonatal care. Patients with no associated anomaly who are hemodynamically stabilized can benefit from MIS procedures. Reduction of the herniated organs is easier using thoracoscopy. Right CDH, liver lobe herniation, and the need for a patch closure are the most frequent reasons for conversion.

All rights reserved.13 ref.09-0329289PASurgical endoscopyUSABackground Minimally invasive surgery (MIS) for late-presenting congenital diaphragmatic hernia (CDH) has been described previously, but few neonatal cases of CDH have been reported. This study aimed to report the multicenter experience of these rare cases and to compare the laparoscopic and thoracoscopic approaches. Methods Using MIS procedures, 30 patients (16 boys and 14 girls) from nine centers underwent surgery for CDH within the first month of life, 26 before day 5. Only one patient had associated malformations. There were 10 pre-term patients (32-36 weeks of gestational age). Their weight at birth ranged from 1,800 to 3,800 g, with three patients weighing less than 2,600 g. Of the 30 patients, 18 were intubated at birth. Results The MIS procedures were performed in 18 cases by a thoracoscopic approach and in 12 cases by a laparoscopic approach. No severe complication was observed. For 20 patients, reduction of the intrathoracic contents was achieved easily with 15 thoracoscopies and 5 laparoscopies. In six cases, the reduction was difficult, proving to be impossible for the four remaining patients: one treated with thoracoscopy and three with laparoscopy. The reasons for the inability to reduce the thoracic contents were difficulty of liver mobilization (1 left CDH and 2 right CDH) and the presence of a dilated stomach in the thorax. Reductions were easier for cases of wide diaphragmatic defects using thoracoscopy. There were 10 conversions (5 laparoscopies and 5 thoracoscopies). The reported reasons for conversion were inability to reduce (n = 4), need for a patch (n = 5), lack of adequate vision (n = 4), narrow working space (n = 1), associated bowel malrotation (n = 1), and an anesthetic problem (n = 1). Five defects were too large for direct closure and had to be closed with a patch. Four required conversion, with one performed through video-assisted thoracic surgery. The recurrences were detected after two primer thoracoscopic closures, one of which was managed by successful reoperation using thoracoscopy. Conclusions In the neonatal period, CDH can be safely closed using MIS procedures. The overall success rate in this study was 67%. The indication for MIS is not related to weeks of gestational age, to weight at birth (if >2,600 g), or to the extent of the immediate neonatal care. Patients with no associated anomaly who are hemodynamically stabilized can benefit from MIS procedures. Reduction of the herniated organs is easier using thoracoscopy.

The photo-electromotive force induced by a speckle pattern vibrating with large amplitude in photorefractive CdTe:V and CdTe:Ge is experimentally studied. This technique is shown to be suitable for transversal amplitude vibration measurement as well as for material response time and associated conductivity characterization. Experiments were carried out with 532 and 1064 nm wavelength illumination over a wide vibration frequency range. The results are in good agreement with a previously reported theoretical model. The studied doped crystals exhibit peculiar different features that are described and discussed.

This study evaluates the effect of a health claim and personal characteristics on the acceptance of two unfamiliar açaí fruit juices that have a low (40% açaí) versus a high (4% açaí) a priori overall liking. Hedonic and sensory measures as well as health- and nutrition-related attribute perceptions and purchase intention were rated before and after health information was presented. Differences in information effects due to interactions with juice type, consumer background attitudes and sociodemographics were investigated. Providing health information yielded a positive, though rather small increase, in overall liking, perceived healthiness and perceived nutritional value of both juices, as well as in their purchase intention. Sensory experiences remained predominant in the acceptance of the fruit juices, although the health claim had a stronger effect on the perceived healthiness and nutritional value of the least-liked juice. Background attitudes and socio-demographic characteristics influenced consumers' acceptance of both unfamiliar fruit juices. Health-oriented consumers were more likely to compromise on taste for an eventual health benefit, though they still preferred the best tasting juice.

Hedonic and sensory measures as well as health- and nutrition-related attribute perceptions and purchase intention were rated before and after health information was presented. Differences in information effects due to interactions with juice type, consumer background attitudes and sociodemographics were investigated. Providing health information yielded a positive, though rather small increase, in overall liking, perceived healthiness and perceived nutritional value of both juices, as well as in their purchase intention. Sensory experiences remained predominant in the acceptance of the fruit juices, although the health claim had a stronger effect on the perceived healthiness and nutritional value of the least-liked juice. Background attitudes and socio-demographic characteristics influenced consumers' acceptance of both unfamiliar fruit juices. Health-oriented consumers were more likely to compromise on taste for an eventual health benefit, though they still preferred the best tasting juice.

Extraction of hydrological information from digital elevation models (DEMs) is a required step when conducting any spatially distributed hydrological modelling. In particular, automated methods are proposed to extract the drainage structure from the DEM. However, a realistic river network is not always derived from conventional DEM processing methods. Indeed, inaccuracy occurs in flat areas corresponding to floodplains. In these areas, additional sources of information are required to extract the correct drainage direction from the DEM. In this study, it is demonstrated that traditional approaches of DEM-preprocessing such as the commonly known 'stream burning' fail to provide correct maps of drainage directions and catchment areas when the extension of flat areas is large. A new method is proposed to take advantage of available imagery data. This method is based on a 'double DEM burning' process: DEM is first burned in the main rivers using the channel network, and then in the floodplain using the spatial distribution of floodplains provided by classified satellite images. In this sense, the method has been referred to as the floodplain burning approach (or simply FB approach). Spatial distribution of floodplains is derived from a multitemporal SAR image classification. A system of equations is used to vary the elevation offset required to be 'burnt' in each cell representing the floodplain, according to the minimal distance from the channel network, which is calculated by a distance transformation. The FB approach was applied to a sub-basin located within the larger Amazon River basin. The region is characterized by large floodplain extensions. Basin delineation maps derived from the new method were compared with those obtained from the traditional stream burning method and highlighted more realistic results.

Lactococci are noninvasive bacteria frequently used as protein delivery vectors and, more recently, as in vitro and in vivo DNA delivery vehicles. We previously showed that a functional eukaryotic enhanced green fluorescent protein (eGFP) expression plasmid vector was delivered in epithelial cells by Lactococcus lactis producing Listeria monocytogenes internalin A (L. lactis InlA+), but this strategy is limited in vivo to transgenic mice and guinea pigs. In this study, we compare the internalization ability of L. lactis InlA+ and L. lactis producing either the fibronectin-binding protein A of Staphylococcus aureus (L. lactis FnBPA+) or its fibronectin binding domains C and D (L. lactis CD+). L. lactis FnBPA+ and L. lactis InlA+ showed comparable internalization rates in Caco-2 cells, while the internalization rate observed with L. lactis CD+ was lower. As visualized by conventional and confocal fluorescence microscopy, large clusters of L. lactis FnBPA+, L. lactis CD+, and L. lactis InlA+ were present in the cytoplasm of Caco-2 cells after internalization. Moreover, the internalization rates of Lactobacillus acidophilus NCFM and of an NCFM mutant strain with the gene coding for the fibronectin-binding protein (fbpA) inactivated were also evaluated in Caco-2 cells. Similar low internalization rates were observed for both wild-type L. acidophilus NCFM and the fbpA mutant, suggesting that commensal fibronectin binding proteins have a role in adhesion but not in invasion. L. lactis FnBPA+, L. lactis CD+, and L. lactis InlA+ were then used to deliver a eukaryotic eGFP expression plasmid in Caco-2 cells: flow cytometry analysis showed that the highest percentage of green fluorescent Caco-2 cells was observed after coculture with either L. lactis FnBPA+ or L. lactis InlA+. Analysis of the in vivo efficiency of these invasive recombinant strains is currently in progress to validate their potential as DNA vaccine delivery vehicles.

Objectives. We investigated involvement and cooperation patterns of local Brazilian AIDS program actors and the consequences of these patterns for program implementation and sustainability. Methods. We performed a public policy analysis (documentary analysis, direct observation, semistructured interviews of health service and nongovernmental organization [NGO] actors) in 5 towns in 2 states, São Paulo and Pará. Results. Patterns suggested 3 models. In model 1, local government, NGOs, and primary health care services were involved in AIDS programs with satisfactory response to new epidemiological trends but a risk that HIV/AIDS would become low priority. In model 2, mainly because of NGO activism, HIV/AIDS remained an exceptional issue, with limited responses to new epidemiological trends and program sustainability undermined by political instability. In model 3, involvement of public agencies and NGOs was limited, with inadequate response to epidemiological trends and poor mobilization threatening program sustainability. Conclusions, Within a common national AIDS policy framework, the degree of involvement and cooperation between public and NGO actors deeply impacts population coverage and program sustainability. Specific processes are required to maintain actor mobilization without isolating AIDS programs.

We investigated involvement and cooperation patterns of local Brazilian AIDS program actors and the consequences of these patterns for program implementation and sustainability. Methods. We performed a public policy analysis (documentary analysis, direct observation, semistructured interviews of health service and nongovernmental organization [NGO] actors) in 5 towns in 2 states, São Paulo and Pará. Results. Patterns suggested 3 models. In model 1, local government, NGOs, and primary health care services were involved in AIDS programs with satisfactory response to new epidemiological trends but a risk that HIV/AIDS would become low priority. In model 2, mainly because of NGO activism, HIV/AIDS remained an exceptional issue, with limited responses to new epidemiological trends and program sustainability undermined by political instability. In model 3, involvement of public agencies and NGOs was limited, with inadequate response to epidemiological trends and poor mobilization threatening program sustainability. Conclusions, Within a common national AIDS policy framework, the degree of involvement and cooperation between public and NGO actors deeply impacts population coverage and program sustainability. Specific processes are required to maintain actor mobilization without isolating AIDS programs.002B30A11; 002B05C02D; 002B06D01Aspect politique; Modèle; SIDA; Surveillance; Contrôle; Brésil; Santé publique; HommeVirose; Infection; Amérique du Sud; Amérique; Immunodéficit; ImmunopathologiePolitical aspect; Models; AIDS; Surveillance; Check; Brazil; Public health; HumanViral disease; Infection; South America; America; Immune deficiency; ImmunopathologyAspecto político; Modelo; SIDA; Vigilancia; Control; Brasil; Salud pública; HombreINIST-2009.35400018847849026009-0335032

CONTEXTE: La tuberculose (TB), une maladie qui peut être prévenue et guérie, reste une menace majeure pour la santé publique dans les régions les plus pauvres des Amériques. Depuis 1993, la stratégie DOTS a été mise en œuvre pour lutter contre la TB dans la région, et depuis 2006 également la nouvelle stratégie Stop TB, qui insiste sur l'extension d'une stratégie DOTS de haute qualité. OBJECTIFS: Décrire l'épidémiologie de la TB dans la région des Amériques entre 1994 et 2005 afin d'analyser les progrès et les perspectives de lutte antituberculeuse en ce qui concerne la réalisation de l'Objectif 6 des MDG d'ici 2015. MÉTHODES: On a collationné dans les bases de données de l'Organisation mondiale de la Santé (OMS) entre 1994 et 2005 les taux d'incidence, de mortalité et de prévalence de la TB, ainsi que la couverture par DOTS et les taux de succès du traitement couvert par DOTS. R É S U LTATS: La couverture par DOTS et les taux de succès du traitement DOTS ont augmenté régulièrement entre 1994 et 2005. En 2005, 88% de la population a été couvert par DOTS et un taux de réussite de 80% a été observé à la fin de 2004. Les taux d'incidence, de prévalence et de mortalité de la TB ont également diminué de façon régulière entre 1994 et ce jour, mais ils varient en fonction des différents scénarios. CONCLUSIONS: A l'exception de quelques pays, une réduction ultérieure de l'incidence, de la prévalence et des décès de la TB est possible d'ici 2015. Une large mise en œuvre du DOTS doit être maintenue pour arriver aux cibles de l'OMS et atteindre les objectifs des MDG.

The Upper Pleistocene/Lower Holocene fossil-bearing sites of the Serra da Capivara National Park Region have yielded three cervid species: Mazama gouazoubira, M. americana and Blastocerus dichotomus, all currently living in South America, the two first in the region. A grand total of more than one hundred remains demonstrates the presence of Mazama gouazoubira in seven sites, mainly the Toca das Moendas, the Toca do Serrote do Artur, the Toca da Cima dos Pilão. This small species shows, since the Upper Pleistocene, a conspicuous tendency to reduce the average dimensions of its teeth and long bones. From the taller M. americana, only a dozen of remains were found in four sites, mainly the Sitio do Meio. In ail of these it is sympatric with M. gouazoubira. It differs from this last one by its cheek teeth and its limb bones size and proportions. The oldest site where the species is known is Tarija (Bolivia, Middle Pleistocene) and it does not show any significant changes in size and proportions between recent and fossil samples. Sixteen remains of the large B. dichotomus were found in five sites, mainly the Toca das Moendas and the Toca da Barra do Antonião. The species is a rare fossil, but is frequently figured in the rock art painting of the region, where it is presently unknown.

Background/Aims: Dent's disease is caused by mutations in the chloride/proton antiporter, CLC-5, or oculo-cerebro-renal-syndrome-of-Lowe (OCRL1) genes. Methods: Eighteen probands with Dent's disease were investigated for mutations in CLC-5 and two of its interacting proteins, CLC-4 and cofilin. Wild-type and mutant CLC-5s were assessed in kidney cells. Urinary calcium excretion following an oral calcium challenge was studied in one family. Results: Seven different CLC-5 mutations consisting of two nonsense mutations (Arg347Stop and Arg718Stop), two missense mutations (Ser244Leu and Arg516Trp), one intron 3 donor splice site mutation, one deletion-insertion (nt930delTCinsA) and an in-frame deletion (523delVal) were identified in 8 patients. In the remaining 10 patients, DNA sequence abnormalities were not detected in the coding regions of CLC-4 or cofilin, and were independently excluded for OCRL1. Patients with CLC-5 mutations were phenotypically similar to those without. The donor splice site CLC-5 mutation resulted in exon 3 skipping. Electrophysiology demonstrated that the 523delVal CLC-5 mutation abolished CLC-5-mediated chloride conductance. Sixty percent of women with the CLC-5 deletion-insertion had nephrolithiasis, although calcium excretion before and after oral calcium challenge was similar to that in unaffected females. Conclusions: Three novel CLC-5 mutations were identified, and mutations in OCRL1, CLC-4 and cofilin excluded in causing Dent's disease in this patient cohort.

All rights reserved.42 ref.09-0337198PAThe Nephron journalsCHEBackground/Aims: Dent's disease is caused by mutations in the chloride/proton antiporter, CLC-5, or oculo-cerebro-renal-syndrome-of-Lowe (OCRL1) genes. Methods: Eighteen probands with Dent's disease were investigated for mutations in CLC-5 and two of its interacting proteins, CLC-4 and cofilin. Wild-type and mutant CLC-5s were assessed in kidney cells. Urinary calcium excretion following an oral calcium challenge was studied in one family. Results: Seven different CLC-5 mutations consisting of two nonsense mutations (Arg347Stop and Arg718Stop), two missense mutations (Ser244Leu and Arg516Trp), one intron 3 donor splice site mutation, one deletion-insertion (nt930delTCinsA) and an in-frame deletion (523delVal) were identified in 8 patients. In the remaining 10 patients, DNA sequence abnormalities were not detected in the coding regions of CLC-4 or cofilin, and were independently excluded for OCRL1. Patients with CLC-5 mutations were phenotypically similar to those without. The donor splice site CLC-5 mutation resulted in exon 3 skipping. Electrophysiology demonstrated that the 523delVal CLC-5 mutation abolished CLC-5-mediated chloride conductance. Sixty percent of women with the CLC-5 deletion-insertion had nephrolithiasis, although calcium excretion before and after oral calcium challenge was similar to that in unaffected females. Conclusions: Three novel CLC-5 mutations were identified, and mutations in OCRL1, CLC-4 and cofilin excluded in causing Dent's disease in this patient cohort.002B14Mutation02Mutation02Mutación02Génétique03Genetics03Genética03Homme05Human05Hombre05Néphrologie06Nephrology06Nefrología06Urologie08Urology08Urología08CofilineCD96CofilinCD96Maladie de DentCD97Dent diseaseCD97Enfermedad de DentCD97Gène OCRL1CD98OCRL1 geneCD98243OTOOTOPASCAL 09-0337198 INISTMutational Analysis of CLC-5, Cofilin and CLC-4 in Patients with Dent's DiseaseFIONA WU; REED (Anita A.

Objectifs. - Le but de cette étude était de démontrer la validité du seuil de pénibilité perçue à l'effort (PET) à partir de relations avec des repères physiologiques caractérisant la capacité aérobie, obtenus lors de tests incrémentés et à intensité constante. Méthodes. - Onze étudiants masculins ont effectué 1) un test incrémenté pour déterminer le premier (VT1) et second (VT2) seuil ventilatoire, la consommation maximale d'oxygène ( VO2max) et la puissance maximale aérobie (MAP) ; 2) quatre exercices rectangulaires pour l'estimation de la puissance critique (CP) et de PET. Résultats. - La consommation d'oxygène (VO2) à VT1 et VT2 était 22,9±4,2 et 35.8±4,7 ml/kg par minute, respectivement. La MAP et VO2max moyenne était 267 ± 34 W et 40,3 ± 6,3 ml/kg par minute, respectivement. PET (146±31 W) et CP (146±33 W) n'étaient pas significativement différents, et étaient tout deux entre VT1 (121±28 W) et VT2 (228±36 W). La corrélation entre PET et CP, exprimés de manière relative au poids de corps, était significative (p 0,01, r=0,84). Les corrélations entre PET et la VO2 relative à VT1 (r=0,76), VT2 (r=0,72) et VO2max (r=0,73) étaient significatives (p < 0,05). Conclusion. - PET n'était pas significativement différent de CP et présentait des corrélations significatives avec VT1, VT2 et VO2max obtenues lors du test incrémental. Cela suggère la validité de PET comme une mesure indirecte des capacités aérobies.

This study focuses on the fate of chromium during ultramafic weathering under tropical conditions. Three soils were studied along a characteristic catena on the ultramafic outcrop of Niquelândia, Brazil. In these soils, the Cr-bearing minerals are inherited chromites (15.4-26.8 wt.% Cr) and magnetites (0.4-4.8 wt.% Cr) and secondary minerals such as iron oxides (0-2 wt.% Cr) or Ni-smectites (0-6.8 wt.% Cr). Indeed, during weathering, Cr liberated from primary minerals can first be incorporated into Ni-smectites (garnierite) or Fe oxides. As the weathering continues, smectites become unstable and Cr liberated into the soil solution, and incorporates in Fe oxides. In this oxidized environment, Fe and Mn are oxidized and oxides can incorporate elements like Cr, Ni and Al. Two types of chromites were distinguished, i.e. a vein type (VC) and a rock type (RC) according to their composition. Chromites could be used as tracer of pedogenesis processes due to the distinct composition ofVC and RC types. They allow us to show that the upper part of some soil profile results exclusively from colluvial processes, and the lower part of the profile results from the ultramafic bedrock weathering. The chromite tracer allows us to propose a model of the catena evolution.

Brasil and Bolivia have water plans projects on the Beni-Madeira river, a major tributary of the Amazon. There are four main tributaries to the Rio Madeira: the Guapore, the Mamore and the Beni rivers into the Bolivian territory, and the Madre de Dios River crossing the North of Bolivia, coming from Peru. Most parts of these rivers are very far from the Andean capital cities of Bolivia and Peru, unreachable for long periods of time. Very few gauging stations are in operation, either for the Bolivian or the Peruvian part, most of them being located at the Andes piedmont or near the confluence at the Brazilian border as they form the Madeira river.

A pathogenesis-related (PR) protein from Theobroma cacao (TcPR-10) was identified from a cacao-Moniliophthora perniciosa interaction cDNA library. Nucleotide and amino acid sequences showed homology with other PR-10 proteins having P loop motif and Betv1 domain. Recombinant TcPR-10 showed in vitro and in vivo ribonuclease activity, and antifungal activity against the basidiomycete cacao pathogen M. perniciosa and the yeast Saccharomyces cerevisiae. Fluorescein isothiocyanate-labeled TcPR-10 was internalized by M. perniciosa hyphae and S. cerevisiae cells and inhibited growth of both fungi. Energy and temperature-dependent internalization of the TcPR-10 suggested an active importation into the fungal cells. Chronical exposure to TcPR-10 of 29 yeast mutants with single gene defects in DNA repair, general membrane transport, metal transport, and antioxidant defenses was tested. Two yeast mutants were hyperresistant compared with their respective isogenic wild type: ctr3Δ mutant, lacking the high-affinity plasma membrane copper transporter and mac1Δ, the copper-sensing transcription factor involved in regulation of high-affinity copper transport. Acute exposure of exponentially growing yeast cells revealed that TcPR-10 resistance is also enhanced in the Snq2 export permease-lacking mutant which has reduced intracellular presence of TcPR-10.

We present herein a comparison of the magnetic properties of bulk ceramics and thin films of the ferrimagnetic ErCo0.50Mn0.50O3 compound. Epitaxial thin films were deposited onto (100) SrTiO3 substrates by pulsed-laser ablation while bulk ceramics were prepared by solid state reaction. When cooling under low applied fields, a spin reversal is observed in both thin film and bulk due to the competition between two magnetic sublattices (Co/Mn and Er) coupled by a negative exchange interaction. Original features are observed in the M(H) loops for bulk materials: abrupt jumps at 4T due to a reorientation of domains, while in the low field region, the increasing and decreasing branches of the magnetization intersect each other. In the thin film, the ordering temperature increased from 69 to 75 K, and the ZFC anomaly (AF transition) became sharper, compared to the bulk specimen. The oxygen content and the microstructure are crucial to observe the intersection of the magnetization branches.

Context. Evolved low-mass stars (0.8 ≤ M/M◦. ≤ 2.5) of a wide range of metallicity bear signatures of a non-standard mixing event in their surface abundances of Li, C, and N, and in their 12C/13C ratio. A Na overabundance has also been reported in some giants of open clusters but remains controversial. The cause of the extra-mixing has been attributed to thermohaline convection that should take place after the RGB bump for low-mass stars and on the early-AGB for more massive objects. Aims. To track the occurrence of this process over a wide mass range, we derive in a homogeneous way the abundances of C, N, O, and Na, as well as the 12C/13C ratio in a sample of 31 giants of 10 open clusters with turn-off masses from 1.7 to 3.1 M◦.. The sample includes red giants, clump giants, and early-AGB stars. We study the observational behavior of the abundances as well as the possible correlations between different elements and between the chemical abundances and stellar mass. Methods. A model atmosphere analysis is conducted using high signal-to-noise ratio, high-resolution FEROS and EMMI spectra. We derive atmospheric parameters using Fe and Fe II lines. We calculate abundances for Na, C, N, and O, as well as the 12C/13C ratio using spectral synthesis. For the elements Mg, Ca, Si, Sc, Ti, V, Cr, Co, and Ni, abundances are derived using equivalent widths. Results. A group of first ascent red giants with M/M◦. ≤ 2.5 exhibits lower [N/C] ratios than those measured in clump giants of the same mass range, suggesting an additional increase in the [N/C] ratio after the first dredge-up. The sodium abundances corrected from NLTE are found to be about solar. [Na/Fe] shows a slight increase of 0.10 dex as a function of stellar mass in the 1.8 to 3.2 M◦. range covered by our sample, in agreement with standard first dredge-up predictions. Our results do not support previous claims of sodium overabundances as high as +0.60 dex. An anti-correlation between 12C/13C and turn-off mass is identified and interpreted as being caused by a post-bump thermohaline mixing. Moreover, we find low 12C/13C ratios in a few intermediate-mass early-AGB stars, confirming that an extra-mixing process also operates in stars that do not experienced the RGB bump. In this case, the extra-mixing possibly acts on the early-AGB, in agreement with theoretical expectations for thermohaline mixing.

Evolved low-mass stars (0.8 ≤ M/M◦. ≤ 2.5) of a wide range of metallicity bear signatures of a non-standard mixing event in their surface abundances of Li, C, and N, and in their 12C/13C ratio. A Na overabundance has also been reported in some giants of open clusters but remains controversial. The cause of the extra-mixing has been attributed to thermohaline convection that should take place after the RGB bump for low-mass stars and on the early-AGB for more massive objects. Aims. To track the occurrence of this process over a wide mass range, we derive in a homogeneous way the abundances of C, N, O, and Na, as well as the 12C/13C ratio in a sample of 31 giants of 10 open clusters with turn-off masses from 1.7 to 3.1 M◦.. The sample includes red giants, clump giants, and early-AGB stars. We study the observational behavior of the abundances as well as the possible correlations between different elements and between the chemical abundances and stellar mass. Methods. A model atmosphere analysis is conducted using high signal-to-noise ratio, high-resolution FEROS and EMMI spectra. We derive atmospheric parameters using Fe and Fe II lines. We calculate abundances for Na, C, N, and O, as well as the 12C/13C ratio using spectral synthesis. For the elements Mg, Ca, Si, Sc, Ti, V, Cr, Co, and Ni, abundances are derived using equivalent widths. Results. A group of first ascent red giants with M/M◦. ≤ 2.5 exhibits lower [N/C] ratios than those measured in clump giants of the same mass range, suggesting an additional increase in the [N/C] ratio after the first dredge-up. The sodium abundances corrected from NLTE are found to be about solar. [Na/Fe] shows a slight increase of 0.10 dex as a function of stellar mass in the 1.8 to 3.2 M◦. range covered by our sample, in agreement with standard first dredge-up predictions. Our results do not support previous claims of sodium overabundances as high as +0.60 dex.

Background. Recombinant forms of Neisseria meningitidis human factor H binding protein (fHBP) are undergoing clinical trials in candidate vaccines against invasive meningococcal serogroup B disease. We report an extensive survey and phylogenetic analysis of the diversity of fhbp genes and predicted protein sequences in invasive clinical isolates obtained in the period 2000-2006. Methods. Nucleotide sequences of fhbp genes were obtained from 1837 invasive N. meningitidis serogroup B (MnB) strains from the United States, Europe, New Zealand, and South Africa. Multilocus sequence typing (MLST) analysis was performed on a subset of the strains. Results. Every strain contained the fhbp gene. All sequences fell into 1 of 2 subfamilies (A or B), with 60%-75% amino acid identity between subfamilies and at least 83% identity within each subfamily. One fHBP sequence may have arisen via inter-subfamily recombination. Subfamily B sequences were found in 70% of the isolates, and subfamily A sequences were found in 30%.

Nucleotide sequences of fhbp genes were obtained from 1837 invasive N. meningitidis serogroup B (MnB) strains from the United States, Europe, New Zealand, and South Africa. Multilocus sequence typing (MLST) analysis was performed on a subset of the strains. Results. Every strain contained the fhbp gene. All sequences fell into 1 of 2 subfamilies (A or B), with 60%-75% amino acid identity between subfamilies and at least 83% identity within each subfamily. One fHBP sequence may have arisen via inter-subfamily recombination. Subfamily B sequences were found in 70% of the isolates, and subfamily A sequences were found in 30%.

Background: The depth of veins can discourage surgeons from creating radial-cephalic arteriovenous accesses for hemodialysis in obese patients. Elevation and tunneled transposition are the two techniques that have been described to superficialize these veins and make them accessible for cannulation. Unfortunately, such manipulation of veins has potential drawbacks. We report lipectomy, a new technique that removes subcutaneous fat and does not mobilize the vein. Methods: This single-center prospective study included 49 consecutive patients (17 men, 32 women) who underwent second-stage lipectomy after creation of a radial-cephalic fistula. Mean patient age was 54 years, 36% had diabetes, and the mean body mass index was 31 ± 5.6 kg/m2. Subcutaneous fatty tissues were removed after two transverse skin incisions under regional anesthesia and preventive hemostasis. Cannulation was first allowed 1 month later, after clinical and color duplex ultrasound evaluation. Technical success was defined as the ability to remove the fat and to palpate the patent vein immediately under the skin at the end of the operation. Clinical success was defined as the ability to perform at least three consecutive dialysis sessions with two needles. All patients were checked systematically every 6 months by the surgeon. Results: Technical and clinical success rates were 96% (47 of 49) and 94% (46 of 49), respectively. Mean vein depth decreased from 8 ± 2 to 3 ± 1 mm according to duplex ultrasound imaging. The mean vein diameter increased from 6 ± 1 to 8 ± 2 mm. In one patient, vein tortuosity that was overlooked required conventional repeat tunneling. One extensive hematoma resulted in loss of the fistula. One patient died before the fistula could be used. Primary patency rates were 71% ± 7% and 63% ± 8% at 1 and 3 years, respectively, and secondary patency rates were 98% ± 2% and 88% ± 7%. Delayed complications were treated by surgery (n = 7) or by endovascular procedures (n = 10). Conclusion: Lipectomy is a safe, effective, and durable approach to make deep arterialized forearm veins accessible for routine cannulation for hemodialysis in obese patients. It might even be hypothesized that incident obese dialysis patients will eventually have the highest proportion of radial-cephalic fistulas because they often have distal veins that have been preserved by their fat from previous attempts at cannulation for blood sampling or infusion.

Ozonation of two azo dyes was investigated in a monitored bench scale bubble column reactor (8.5-L), varying liquid media salt content (0, 1, 40 and 100 gL-1, NaCl). In experiments with Orange II pH was varied (5, 7.5 and 9) but ozonation of Acid Red 27 was performed at pH 7.5. Ozone self-decomposition rate-constant increased with salt concentration. Color removal was very effective and fast achieved under all experimental conditions. For the two azo dyes tested, more than 98% of color intensity was removed in 30-min ozonation assays. However, only partial mineralization of azo dyes (45%-Orange II; 20%-Acid Red 27) was attained in such experiments. The degree of mineralization (TOC removal) was negatively affected by salt concentration. Biodegradation assays conducted by respirometry revealed the inhibitory effect of dye degradation products formed during ozonation.

Adaptive strategies in space and time allow considerable speed-up of finite volume schemes for conservation laws, while controlling the accuracy of the discretization. In this paper, a multiresolution technique for finite volume schemes with explicit time discretization is presented. An adaptive grid is introduced by suitable thresholding of the wavelet coefficients, which maintains the accuracy of the finite volume scheme of the regular grid. Further speed-up is obtained by local scale-dependent time stepping, i.e., on large scales larger time steps can be used without violating the stability condition of the explicit scheme. Furthermore, an estimation of the truncation error in time, using embedded Runge-Kutta type schemes, guarantees a control of the time step for a given precision. The accuracy and efficiency of the fully adaptive method is illustrated with applications for compressible Euler equations in one and two space dimensions.

Learning how to extract texture features from noncontrolled environments characterized by distorted images is a still-open task. By using a new rotation-invariant and scale-invariant image descriptor based on steerable pyramid decomposition, and a novel multiclass recognition method based on optimum-path forest, a new texture recognition system is proposed. By combining the discriminating power of our image descriptor and classifier, our system uses small-size feature vectors to characterize texture images without compromising overall classification rates. State-of-the-art recognition results are further presented on the Brodatz data set. High classification rates demonstrate the superiority of the proposed system.

Background/Aims: Drinking red wine is associated with a decreased mortality from coronary heart diseases. This study examined whether polyphenols contained in a grape skin extract (GSE) triggered the endothelial formation of nitric oxide (NO) and investigated the underlying mechanism. Methods: Vascular reactivity was assessed in organ chambers using porcine coronary artery rings in the presence of indomethacin (a cyclooxygenase inhibitor) and charybdotoxin plus apamin (inhibitors ofendothelium-derived hyper-polarizing factor-mediated responses).The phosphorylation level of Src, Akt and endothelial NO synthase (eNOS) were assessed by Western blot analysis, and the formation of reactive oxygen species (ROS) was investigated using dihydro-ethidine and dichlorodihydrofluorescein. Results: GSE-induced endothelium-dependent relaxations were abolished by NG-nitro-L-arginine (an eNOS inhibitor) and ODQ (a soluble guanylyl cyclase inhibitor), and they were reduced by MnTMPyP, polyethyleneglycol catalase, PP2 (an inhibitor of Src kinase) and wortmannin (an inhibitor of phosphoinositide 3-kinase). GSE caused phosphorylation of Src, which was prevented by MnTMPyP. It also caused phosphorylation of Akt and eNOS, which were prevented by MnTMPyP, polyethyleneglycol catalase, PP2, wortmannin and LY294002. GSE elicited the formation of ROS in native and cultured endothelial cells, which was prevented by MnTMPyP. Conclusions: GSE causes endothelium-dependent NO-mediated relaxations of coronary arteries. This effect involves the intracellular formation of ROS in endothelial cells leading to the Src kinase/phosphoinositide 3-kinase/Akt-dependent phosphorylation of eNOS.

Calcium-binding protein S100A9 and its C-terminus peptide (mS100A9p) are anti-inflammatory and induce antinociception in rodents. We investigated the mechanisms involved in this effect, and whether they depend or not on the anti-inflammatory properties of mS100A9p. In mice, mS100A9p inhibited thermal and mechanical hyperalgesia and allodynia induced by either carrageenan or formalin, without interfering with paw edema. mS100A9p also inhibited myeloperoxidase activity (MPO), a marker of granulocyte infiltration, induced by carrageenan, but increased MPO after formalin intraplantar injection. The in vivo analgesic properties of mS100A9p were independent of opioid receptor activation. Calcium flux into dorsal root ganglia neurons induced by KCl was inhibited by mS100A9p, suggesting that this protein is able to inhibit signaling, in sensory neurons. The inhibitory effects of mS100A9p on primary afferent signaling were neither due to intracellular calcium store inhibition nor to calcium chelating properties. However, mS100A9p was able to inhibit calcium currents carried by transiently expressed N-type, but not L-type calcium channels, as demonstrated both by gene transfection techniques and electrophysiology. These data demonstrate that mS100A9p interferes with mechanisms involved in nociception, hyperalgesia and calcium signaling in sensory neurons, modulating primary afferent nociceptive signal by inhibiting activation of N-type voltage operated calcium channels.

These data demonstrate that mS100A9p interferes with mechanisms involved in nociception, hyperalgesia and calcium signaling in sensory neurons, modulating primary afferent nociceptive signal by inhibiting activation of N-type voltage operated calcium channels.002B02Analgésique01Analgesic01Analgésico01Séquence C terminale02C terminal-Sequence02Secuencia C terminal02Mécanisme action03Mechanism of action03Mecanismo acción03Canal ionique04Ionic channel04Canal iónico04CalciumNCFR05CalciumNCFR05CalcioNCFR05Inhibiteur06Inhibitor06Inhibidor06Analgésie07Analgesia07Analgesia07Ganglion spinal08Spinal ganglion08Ganglio espinal08Neurone09Neuron09Neurona09Inflammation10Inflammation10Inflamación10Canal calcique N11N-type calcium channel11Canal calcio tipo N11Calgranuline BCD96Calgranulin BCD96Elément minéral37Inorganic element37Elemento inorgánico37Moelle épinière38Spinal cord38Médula espinal38Système nerveux central39Central nervous system39Sistema nervioso central39257OTOOTOPASCAL 09-0356132 INISTAnalgesic properties of S100A9 C-terminal domain: a mechanism dependent on calcium channel inhibitionSQUARZONI DALE (Camila); ALTIER (Christophe); CENAC (Nicolas); GIORGI (Renata); APARECIDA JULIANO (Maria); JULIANO (Luiz); ZAMPONI (Gerald W.); VERGNOLLE (Nathalie)INSERM, U563, Centre de Physiopathologie de Toulouse Purpan/Toulouse 31 300/France (1 aut., 3 aut., 8 aut.); Université Toulouse III Paul Sabatier/Toulouse 31000/France (1 aut., 3 aut., 8 aut.); Department of Physiology and Biophysics Hotchkiss Brain Institute, University of Calgary/Calgary, AB T2N 4N1/Canada (2 aut., 7 aut.); Laboratory of Pathophysiolog,y.

We investigated the mechanisms involved in this effect, and whether they depend or not on the anti-inflammatory properties of mS100A9p. In mice, mS100A9p inhibited thermal and mechanical hyperalgesia and allodynia induced by either carrageenan or formalin, without interfering with paw edema. mS100A9p also inhibited myeloperoxidase activity (MPO), a marker of granulocyte infiltration, induced by carrageenan, but increased MPO after formalin intraplantar injection. The in vivo analgesic properties of mS100A9p were independent of opioid receptor activation. Calcium flux into dorsal root ganglia neurons induced by KCl was inhibited by mS100A9p, suggesting that this protein is able to inhibit signaling, in sensory neurons. The inhibitory effects of mS100A9p on primary afferent signaling were neither due to intracellular calcium store inhibition nor to calcium chelating properties. However, mS100A9p was able to inhibit calcium currents carried by transiently expressed N-type, but not L-type calcium channels, as demonstrated both by gene transfection techniques and electrophysiology.

American trypanosomiasis is a parasitic zoonosis that occurs throughout Latin America. The etiological agent, Trypanosoma cruzi, is able to infect almost all tissues of its mammalian hosts and spreads in the environment in multifarious transmission cycles that may or not be connected. This biological plasticity, which is probably the result of the considerable heterogeneity of the taxon, exemplifies a successful adaptation of a parasite resulting in distinct outcomes of infection and a complex epidemiological pattern. In the 1990s, most endemic countries strengthened national control programs to interrupt the transmission of this parasite to humans. However, many obstacles remain to the effective control of the disease. Current knowledge of the different components involved in elaborate system that is American trypanosomiasis (the protozoan parasite T. cruzi, vectors Triatominae and the many reservoirs of infection), as well as the interactions existing within the system, is still incomplete. The Triatominae probably evolve from predatory reduvids in response to the availability of vertebrate food source. However, the basic mechanisms of adaptation of some of them to artificial ecotopes remain poorly understood. Nevertheless, these adaptations seem to be associated with a behavioral plasticity, a reduction in the genetic repertoire and increasing developmental instability.

Objective: Fast-track rehabilitation is a group of simple measures that reduces morbidity, postoperative complication and accelerates postoperative rehabilitation reducing hospital stay. It can be applied to lung cancer lobectomy. Fast-track rehabilitation cornerstones are: minimally invasive surgical techniques using video-assisted and muscle sparring incisions, normovolemia, normothermia, good oxygenation, euglicemia, no unnecessary antibiotics, epidural patient-controlled analgesia, systemic opiods-free analgesia, early ambulation and oral feeding. Our objective is to describe a five-year experience with fast-track rehabilitation for lung cancer lobectomy. Patients and methods: A retrospective non-controlled study including 109 consecutive patients submitted to fast-track rehabilitation in the postoperative care of lung cancer lobectomy was performed. Only collaborative patients who could receive double-lumen intubation, epidural catheters with patient-controlled analgesia, who had Karnofsky index of 100, previous normal feeding and ambulation, absence of morbid obesity, diabetes or asthma, were eligible. Postoperative oral feeding and aggressive ambulation started as soon as possible. Results: Immediate postoperative extubation even in the operation room was possible in 107 patients and oral feeding and ambulation were possible before the first hour in 101 patients. Six patients could not receive early oral feeding or ambulate due to hypnosis secondary to preoperative long effect benzodiazepines. Two patients could not ambulate immediately due to epidural catheter misplacement with important postoperative pain. Ninety-nine discharges occurred at the second postoperative day, four of them with a chest tube connected to a Heimlich valve due to air leak. No complication of early feeding and ambulation was observed. Postoperative hypnosis due to long duration benzodiazepines or pain does not allow early oral feeding or ambulation. Avoiding long duration preoperative benzodiazepines, immediate postoperative extubation, regional thoracic PCA and early oral feeding and ambulation were related to a lesser frequency of complication and a shorter hospital stay. Conclusion: Fast-track rehabilitation for lung cancer lobectomies can be safely performed in a selected group of patients if a motivated multidisciplinary group of professionals is available and seems to reduce postoperative complication and hospital stay.

Mast Cells (MCs) express toll-like receptor 2 (TLR2), a receptor known to be triggered by several major mycobacterial ligands and involved in resistance against Mycobacterium tuberculosis (MTB) infection. This study investigated whether adoptive transfer of TLR2 positive MCs (TLR2+/+) corrects the increased susceptibility of TLR2-/- mice to MTB infection. TLR2-/- mice displayed increased mycobacterial burden, diminished myeloid cell recruitment and proinflammatory cytokine production accompanied by defective granuloma formation. The reconstitution of these mice with TLR2+/+ MCs, but not TLR2-/-, confers better control of the infection, promotes the normalization of myeloid cell recruitment associated with reestablishment of the granuloma formation. In addition, adoptive transfer of TLR2+/+ MC to TLR2-/- mice resulted in regulation of the pulmonary levels of IL-β, IL-6, TNF-α, enhanced Th1 response and activated CD8+ T cell homing to the lungs. Our results suggest that activation of MCs via TLR2 is required to compensate the defect in protective immunity and inability of TLR2-/- mice to control MTB infection.

Our results suggest that activation of MCs via TLR2 is required to compensate the defect in protective immunity and inability of TLR2-/- mice to control MTB infection.002A05B15Mycobacterium tuberculosisNS01Mycobacterium tuberculosisNS01Mycobacterium tuberculosisNS01Mastocyte05Mast cell05Mastocito05Cytokine06Cytokine06Citoquina06Inflammation07Inflammation07Inflamación07Lymphocyte T08T-Lymphocyte08Linfocito T08Mycobactériose14Mycobacterial infection14Micobacteriosis14MycobacteriaceaeNSMycobacteriaceaeNSMycobacteriaceaeNSMycobacterialesNSMycobacterialesNSMycobacterialesNSActinomycetesNSActinomycetesNSActinomycetesNSBactérieBacteriaBacteriaBactérioseBacteriosisBacteriosisInfectionInfectionInfección257OTOOTOPASCAL 09-0359283 INISTTLR2-dependent mast cell activation contributes to the control of Mycobacterium tuberculosis infectionCARLOS (Daniela); FRANTZ (Fabiani G.); SOUZA-JUNIOR (Devandir A.); JAMUR (Maria C.); OLIVER (Constance); RAMOS (Simone G.); QUESNIAUX (Valerie F.); RYFFEL (Bernhard); SILVA (Célio L.); BOZZA (Marcelo T.); FACCIOLI (Lúcia H.)Departamento de Análises Clinicas, Toxicológicas e Bromatológicas, Faculdade de Ciências Farmacêuticas de Ribeirão Preto, Universidade de Sào Paulo, Av. do Café, s/n/Ribeirào Preto, SP 14.040-903/Brésil (1 aut., 2 aut., 11 aut.); Departamento de Biologia Celular e Molecular e Bioagentes Patogênicos, Faculdade de Medicina de Ribeirão Preto, Universidade de Sào Paulo/Ribeirão Preto, SP/Brésil (3 aut., 4 aut., 5 aut.); Departamento de Patologia, Faculdade de Medicina de Ribeirão Preto, Universidade de São Paulo/Ribeirão Preto, SP/Brésil (6 aut.); Molecular Immunology and Embryology, Centre National de la Recherche Scientifique/Orléans/France (7 aut., 8 aut.); Departamento de Bioquímica e Imunologia, Faculdade de Medicina de Ribeirão Preto, Universidade de São Paulo/Ribeirão Preto, SP/Brésil (9 aut.); Departamento de Imunologia, Instituto de Microbiologia Prof. Paulo de Góes, Universidade Federal do Rio de Janeiro/RJ/Brésil (10 aut.)

This study investigated whether adoptive transfer of TLR2 positive MCs (TLR2+/+) corrects the increased susceptibility of TLR2-/- mice to MTB infection. TLR2-/- mice displayed increased mycobacterial burden, diminished myeloid cell recruitment and proinflammatory cytokine production accompanied by defective granuloma formation. The reconstitution of these mice with TLR2+/+ MCs, but not TLR2-/-, confers better control of the infection, promotes the normalization of myeloid cell recruitment associated with reestablishment of the granuloma formation. In addition, adoptive transfer of TLR2+/+ MC to TLR2-/- mice resulted in regulation of the pulmonary levels of IL-β, IL-6, TNF-α, enhanced Th1 response and activated CD8+ T cell homing to the lungs.

The aim of a clinical classification of pulmonary hypertension (PH) is to group together different manifestations of disease sharing similarities in pathophysiologic mechanisms, clinical presentation, and therapeutic approaches. In 2003, during the 3rd World Symposium on Pulmonary Hypertension, the clinical classification of PH initially adopted in 1998 during the 2nd World Symposium was slightly modified. During the 4th World Symposium held in 2008, it was decided to maintain the general architecture and philosophy of the previous clinical classifications. The modifications adopted during this meeting principally concern Group 1, pulmonary arterial hypertension (PAH). This subgroup includes patients with PAH with a family history or patients with idiopathic PAH with germline mutations (e.g., bone morphogenetic protein receptor-2, activin receptor-like kinase type 1, and endoglin). In the new classification, schistosomiasis and chronic hemolytic anemia appear as separate entities in the subgroup of PAH associated with identified diseases. Finally, it was decided to place pulmonary venoocclusive disease and pulmonary capillary hemangiomatosis in a separate group, distinct from but very close to Group 1 (now called Group 1'). Thus, Group 1 of PAH is now more homogeneous.

The 4th World Symposium on Pulmonary Hypertension was the first international meeting to focus not only on pulmonary arterial hypertension (PAH) but also on the so-called non-PAH forms of pulmonary hypertension (PH). The term "non-PAH PH" summarizes those forms of PH that are found in groups 2 to 5 of the current classification of PH, that is, those forms associated with left heart disease, chronic lung disease, recurrent venous throm-boembolism, and other diseases. Many of these forms of PH are much more common than PAH, but all of them have been less well studied, especially in terms of medical therapy. The working group on non-PAH PH focused mainly on 4 conditions: chronic obstructive lung disease, interstitial lung disease, chronic thromboembolic PH, and left heart disease. The medical literature regarding the role of PH in these diseases was reviewed, and recommendations regarding diagnosis and treatment of PH in these conditions are provided. Given the lack of robust clinical trials addressing PH in any of these conditions, it is important to conduct further studies to establish the role of medical therapy in non-PAH PH.

The estimation of the entanglement of multipartite systems undergoing decoherence is important for assessing the robustness of quantum information processes. It usually requires access to the final state and its full reconstruction through quantum tomography. General dynamical laws may simplify this task. We found that when one of the parties of an initially entangled two-qubit system is subject to a noisy channel, a single universal curve describes the dynamics of entanglement for both pure and mixed states, including those for which entanglement suddenly disappears. Our result, which is experimentally demonstrated using a linear optics setup, leads to a direct and efficient determination of entanglement through the knowledge of the initial state and single-party process tomography alone, foregoing the need to reconstruct the final state.

We address the question of determining the evolution equation for surface waves propagating in water whose depth is much larger than the typical wavelength of the surface disturbance. We avoid making the usual approximation of supposing the evolution to be given in the form of a modulated wave-packet. We treat the problem by means of a conformal transformation allowing to explicitly find the Dirichletto-Neumann operator for the problem together with asymptotic expansions in parameters measuring the nonlinearity and depth. This allows us to obtain an equation in physical variables valid in the weakly nonlinear, deep-water regime. The equation is an integro-differential equation, which reduces to known cases for infinite depth. We discuss solutions in a perturbative setting and show that the evolution equation describes Stokes-like waves.

This paper presents two blind identification methods for nonlinear memoryless channels in multiuser communication systems. These methods are based on the parallel factor (PARAFAC) decomposition of a tensor composed of channel output covariances. Such a decomposition is possible owing to a new precoding scheme developed for phase-shift keying (PSK) signals modeled as Markov chains. Some conditions on the transition probability matrices (TPM) of the Markov chains are established to introduce temporal correlation and satisfy statistical correlation constraints inducing the PARAFAC decomposition of the considered tensor. The proposed blind channel estimation algorithms are evaluated by means of computer simulations.

Context. Ices present in different astrophysical environments are exposed to ion irradiation from cosmic rays (H to heavier than Fe) in the keV to GeV energy range. Aims. The objective of this work is to study the effects produced in astrophysical ices by heavy ions at relatively high energies (MeV) in the electronic energy loss regime and compare them with those produced by protons. Methods. C18O2 was condensed on a CsI substrate at 13 K and it was irradiated by 46 MeV 58Ni11+ up to a final fluence of 1.5 × 1013 cm-2 at a flux of 2 × 109 cm-2 s-1. The ice was analyzed in situ by infrared spectroscopy (FTIR) in the 5000-600 cm-1 range. Results. The CO2 destruction was observed, as well as the formation of other species such as CO, CO3, O3, and C3. The destruction cross section of CO2 is found to be 1.7 × 10-13 cm2, while those for the formation of CO, CO3, and O3 molecules are 1.6 × 10-13 cm2, 4.5 × 10-14 cm2, and 1.5 × 10-14 cm2 , respectively. The sputtering yield of the CO2 ice is 4.0 × 104 molecules/impact, four orders of magnitude higher than for H projectiles at the same velocity. This allows us to estimate the contribution of the sputtering by heavy ions as compared to protons in the solar winds and in cosmic rays. Conclusions. The present results show that heavy ions play an important role in the sputtering of astrophysical ices. Furthermore, this work confirms the quadratic stopping power dependence of sputtering yields.

Ices present in different astrophysical environments are exposed to ion irradiation from cosmic rays (H to heavier than Fe) in the keV to GeV energy range. Aims. The objective of this work is to study the effects produced in astrophysical ices by heavy ions at relatively high energies (MeV) in the electronic energy loss regime and compare them with those produced by protons. Methods. C18O2 was condensed on a CsI substrate at 13 K and it was irradiated by 46 MeV 58Ni11+ up to a final fluence of 1.5 × 1013 cm-2 at a flux of 2 × 109 cm-2 s-1. The ice was analyzed in situ by infrared spectroscopy (FTIR) in the 5000-600 cm-1 range. Results. The CO2 destruction was observed, as well as the formation of other species such as CO, CO3, O3, and C3. The destruction cross section of CO2 is found to be 1.7 × 10-13 cm2, while those for the formation of CO, CO3, and O3 molecules are 1.6 × 10-13 cm2, 4.5 × 10-14 cm2, and 1.5 × 10-14 cm2 , respectively. The sputtering yield of the CO2 ice is 4.0 × 104 molecules/impact, four orders of magnitude higher than for H projectiles at the same velocity. This allows us to estimate the contribution of the sputtering by heavy ions as compared to protons in the solar winds and in cosmic rays. Conclusions. The present results show that heavy ions play an important role in the sputtering of astrophysical ices. Furthermore, this work confirms the quadratic stopping power dependence of sputtering yields.001E03Ion lourd; Irradiation ion; Glace; Irradiation cosmique; Domaine énergie GeV; Perte énergie; Proton; Spectrométrie IR; Section efficace; Vent solaire; Rayonnement cosmique; Pouvoir arrêt; Processus moléculaireHeavy ions; Ion irradiation; Ice; Cosmic irradiation; GeV range; Energy losses; Protons; Infrared spectroscopy; Cross sections; Solar wind; Cosmic radiation; Stopping power; Molecular processIrradiación ión; Irradiación cósmica; Proceso molecularINIST-14176.35400017182057022009-0371287

Context. TWA22 was initially regarded as a member of the TW Hydrae association (TWA). In addition to being one of the youngest (≃8 Myr) and nearest (≃20 pc) stars to Earth, TWA22 has proven to be very interesting after being resolved as a tight, very lowmass binary. This binary can serve as a very useful dynamical calibrator for pre-main sequence evolutionary models. However, its membership in the TWA has been recently questioned despite due to the lack of accurate kinematic measurements. Aims. Based on proper motion, radial velocity, and trigonometric parallax measurements, we aim here to re-analyze the membership of TWA22 to young, nearby associations. Methods. Using the ESO NTT/SUSI2 telescope, we observed TWA22 AB during 5 different observing runs over 1.2 years to measure its trigonometric parallax and proper motion. This is a part of a larger project measuring trigonometric parallaxes and proper motions of most known TWA members at a sub-milliarcsec level. HARPS at the ESO 3.6 m telescope was also used to measure the system's radial velocity over 2 years. Results. We report an absolute trigonometric parallax of TWA22 AB, π = 57.0 ± 0.7 mas, corresponding to a distance 17.5 ± 0.2 pc from Earth. Measured proper motions of TWA 22AB are μα cos(δ)= -175.8 ± 0.8 mas/yr and μδ = -21.3 ±0.8 mas/yr. Finally, from HARPS measurements, we obtain a radial velocity Vrad = 14.8 ±2.1 km s-1. Conclusions. A kinematic analysis of TWA22 AB space motion and position implies that a membership of TWA22 AB to known young, nearby associations can be excluded except for the β Pictoris and TW Hydrae associations. Membership probabilities based on the system's Galactic space motion and/or the trace-back technique support a higher chance of being a member to the β Pictoris association. Membership of TWA22 in the TWA cannot be fully excluded because of large uncertainties in parallax measurements and radial velocities and to the uncertain internal velocity dispersion of its members.

This paper is a proposal to embed tree-shaped vasculatures in a wall designed such that the wall withstands without excessive hot spots the intense heating that impinges on it. The vasculature is a quilt of square-shaped panels, each panel having a tree vasculature that connects the center with the perimeter. The coolant may flow in either direction, center-perimeter, or perimeter-center, although here only the center-perimeter flow direction is illustrated. Numerical simulations of conjugate heat and fluid flow in three directions show that it is possible to determine all the optimal geometric features of vasculatures with up to three levels of bifurcation (n = 3). The global performance is evaluated in terms of the overall thermal resistance, pressure difference, flow resistance and pumping power. The improvements in global performance diminish as the number of bifurcation levels increases. No flow architecture is universally superior. The dendritic designs are superior at the low and high ends of the pressure difference range. The radial designs are superior at intermediate pressure difference numbers.

Context. The cosmic time around the z ˜ 1 redshift range appears crucial in the cluster and galaxy evolution, since it is probably the epoch of the first mature galaxy clusters. Our knowledge of the properties of the galaxy populations in these clusters is limited because only a handful of z ˜ 1 clusters are presently known. Aims. In this framework, we report the discovery of a z ˜ 0.87 cluster and study its properties at various wavelengths. Methods. We gathered X-ray and optical data (imaging and spectroscopy), and near and far infrared data (imaging) in order to confirm the cluster nature of our candidate, to determine its dynamical state, and to give insight on its galaxy population evolution. Results. Our candidate structure appears to be a massive z ˜ 0.87 dynamically young cluster with an atypically high X-ray temperature as compared to its X-ray luminosity. It exhibits a significant percentage (˜90%) of galaxies that are also detected in the 24 μm band. Conclusions. The cluster RXJ1257.2+4738 appears to be still in the process of collapsing. Its relatively high temperature is probably the consequence of significant energy input into the intracluster medium besides the regular gravitational infall contribution. A significant part of its galaxies are red objects that are probably dusty with on-going star formation.

Astronomy and astrophysics : (Berlin. Print); ISSN 0004-6361; Coden AAEJAF; France; Da. 2009; Vol. 503; No. 2; Pp. 399-408; Bibl. 1/2 p.AnglaisContext. The cosmic time around the z ˜ 1 redshift range appears crucial in the cluster and galaxy evolution, since it is probably the epoch of the first mature galaxy clusters. Our knowledge of the properties of the galaxy populations in these clusters is limited because only a handful of z ˜ 1 clusters are presently known. Aims. In this framework, we report the discovery of a z ˜ 0.87 cluster and study its properties at various wavelengths. Methods. We gathered X-ray and optical data (imaging and spectroscopy), and near and far infrared data (imaging) in order to confirm the cluster nature of our candidate, to determine its dynamical state, and to give insight on its galaxy population evolution. Results. Our candidate structure appears to be a massive z ˜ 0.87 dynamically young cluster with an atypically high X-ray temperature as compared to its X-ray luminosity. It exhibits a significant percentage (˜90%) of galaxies that are also detected in the 24 μm band. Conclusions. The cluster RXJ1257.2+4738 appears to be still in the process of collapsing. Its relatively high temperature is probably the consequence of significant energy input into the intracluster medium besides the regular gravitational infall contribution. A significant part of its galaxies are red objects that are probably dusty with on-going star formation.001E03Evolution amas; Amas galaxies; Evolution galaxies; Observation RX; Amas jeune; Déplacement vers le rouge; Galaxies; Spectrométrie; Haute température; Luminosité; Matière intraamas; Formation stellaire; Amas stellaireCluster evolution; Galaxy clusters; Galaxy evolution; X ray observation; Young cluster; Red shift; Galaxies; Spectroscopy; High temperature; Luminosity; Intracluster matter; Star formation; Star clustersEvolución galaxias; Observación RX; Cúmulo joven; Alta temperatura; Materia intracúmuloINIST-14176.35400018763814009009-0378710

Objectives: To improve the understanding of serogroup Y invasive meningococcal disease (IMD) in Latin America, particularly IMD molecular epidemiology; 166 Y serogroup isolates received at the National Reference Laboratories of Argentina, Brazil, Chile, Colombia, and Costa Rica during 2000-2006 were characterized by their molecular markers. Methods: This analysis included serological assays to determine serogroup/serotype/serosubtype, DNA sequencing and genotyping of the porB and/or porA genes, multilocus sequence typing (MLST) and fetA allele determination. Results: Sixteen different antigenic combinations were observed. Sixty-two (37.3%) isolates were NT:P1.5 and 36 (21.7%) isolates were 14:NST. Thirty-two different STs appeared, but 3 STs (ST-1624, ST-23, and ST-5770) accounted for 69.9% (116) of the strains. Most of the IMD isolates belonged to the ST-23, ST-167 clonal complexes or the group composed by ST-5770 and related STs. Conclusions: Isolates obtained in Colombia and Costa Rica were similar to that of the United States, in that most sequence types belonged to the ST-23 clonal complex. IMD isolates found in Argentina appear to be the result of an independent event and did not spread from nearby countries, being the sequence type ST-1624 (ST-167 clonal complex) the most frequently found. We were unable to correlate an antigenic shift of outer membrane proteins with an increase of serogroup Y meningococcal cases in our collection of isolates.

A retrospective survey was conducted to characterize β-lactamases in a collection of 43 ceftazidime-resistant Pseudomonas aeruginosa isolates recovered from patients with bloodstream infections hospitalized at a Brazilian teaching hospital between January and December 2005. Resistance rates for carbapenems, aminoglycosides, and quinolones were over 80%, with only colistin remaining active against all isolates. Pulsed-field gel electrophoresis analysis identified seven different genotypes. AmpC overproduction was found to be the sole β-lactamase-mediated mechanism responsible for ceftazidime resistance in four isolates (9.3%). Nine isolates (20.9%) produced an extended-spectrum β-lactamase (ESBL), either GES-1 (n = 7, 16.3%) or CTX-M-2 (n = 2, 4.6%). Carbapenemase activity was detected in 30 (70%) additional isolates. Among those isolates, two isolates (4.6%) produced the ESBL GES-5, possessing the ability to hydrolyze imipenem; a single isolate (2.3%) produced the metallo-β-lactamase (MBL) IMP-1; and 27 isolates produced the MBL SPM-1 (62.8%). None of the isolates coproduced both ESBL and MBL. Insertion sequence elements ISCR4 and ISCR1 were associated with blaSPM-1 and MoCTX-M-2 genes, respectively, whereas the blaGES-1 and blaGES-5 genes were part of class 1 integron structures. This study underlines the spread of MBL- and ESBL-producing P. aeruginosa isolates as an important source of ceftazidime resistance in Brazil.

Longinos Navás a décrit approximativement 680 espèces de Chrysopidae. Les spécimens type porte-nom conservés au Muséum national d'Histoire naturelle à Paris (MNHN) représentent environ le quart de ces espèces (soit 174). Ci-après, nous fournissons les données concernant les spécimens types, ainsi que l'historique des changements de nom pour chacune des espèces décrites par Navás et conservées dans les collections entomologiques du MNHN. En plus des 5 holotypes et 58 lectotypes précédemment identifiés de ces collections, 13 holotypes sont nouvellement reconnus, 88 lectotypes sont désignés, et des syntypes sont identifiés pour 10 espèces. Les nouvelles synonymies suivantes sont proposées: Chrysopa aroguesina Navàs, 1929 est un synonyme junior de Ungla laufferi (Navás 1922); Chrysopa camposana Navás, 1935 est un synonyme junior de Ceraeochrysa valida (Banks, 1895); Ceraeochrysa (= Chrysopa) caligata (Banks, 1946) est un synonyme junior de Ceraeochrysa cornuta (Navás, 1925); Chrysopa dampfina Navás 1928 est un synonyme junior de Chrysopodes (Chrysopodes) figuralis (Banks, 1915); Nodita morenoi Navás, 1934 est un synonyme junior de Leucochrysa (Nodita) camposi (Navàs, 1933); Chrysopa rochina Navás, 1915 est un synonyme junior de Ceraeochrysa cincta (Schneider, 1851); Dichochrysa sjostedti [= Chrysopa sjoestedti] (van der Weele, 1910) est un synonyme junior de Dichochrysa nubilata (Navás, 1910). Les nouvelles combinaisons sont établies pour les cinq espèces suivantes: Chrysopodes (Chrysopodes) apurinus (Navás, 1935), Plesiochrysa climacia (Navás, 1935), Ungla favrei (Navás, 1935), Chrysopodes (Chrysopodes) geayi (Navás, 1910), et Ungla laufferi (Navás, 1922). Nous donnons la liste des six types de Navás réputés pour être au Muséum qui n'ont pas été retrouvés. Huit noms d'espèces devront être considéres comme des nomina dubia: jusqu'à ce que les types soient trouvés ou que des néotypes soient désignés, ce sont: Ancylopteryx alluaudi Navás, 1910; A. elgonica Navás, 1936; Chrysopa aegyptiaca Navás, 1915; C. nymphulina Navás, 1915; C. ricciana Navás, 1910; C. rothschildi Navás, 1915; C. silvana Navás, 1913; Nothochrysa sordidata Navás, 1908.

Background and Purpose-Diagnostic delay of cerebral vein and dural sinus thrombosis may have an impact on outcome. Methods-In the International Study on Cerebral Vein and Dural Sinus Thrombosis (ISCVT) cohort (624 patients with cerebral vein and dural sinus thrombosis), we analyzed the predictors and the impact on outcome of diagnostic delay. Primary outcome was a modified Rankin Scale score >2 at the end of follow-up. Secondary outcomes were modified Rankin Scale score 0 to 1 at the end of follow-up, death, and visual deficits (visual acuity or visual field). Results-Median delay was 7 days (interquartile range, 3 to 16). Patients with disturbance of consciousness (P<0.001) and of mental status (P=0.042), seizure (<0.001), and with parenchymal lesions on admission CT/MR (P<0.001) were diagnosed earlier, whereas men (P=0.01) and those with isolated intracranial hypertension syndrome (P=0.04) were diagnosed later. Between patients diagnosed earlier and later than the median delay, no statistically significant differences were found in the primary (P=0.33) and in secondary outcomes: modified Rankin Scale score 0 to 1 (P=0.86) or deaths (P=0.53). Persistent visual deficits were more frequent in patients diagnosed later (P=0.05). In patients with isolated intracranial hypertension syndrome, modified Rankin Scale score >2 at the end of follow-up was more frequent in patients diagnosed later (P=0.02). Conclusions-Diagnostic delay was considerable in this cohort and was associated with an increased risk of visual deficit. In patients with isolated intracranial hypertension syndrome, diagnostic delay was also associated with death or dependency.

In this work, we present the cyclohexane oxidation catalyzed by the mononuclear 1,10-phenantroline Cu(II) complexes: [Cu(phen)3]Cl2.7H2O (1), [Cu(phen)2Cl]Cl.5H2O (2), [Cu(phen)Cl2](3). using hydrogen peroxide as oxidant, in acetonitrile:water (3.5:1) solution. The reactions were carried out at temperatures ranging from 25 °C to 70 °C. All complexes were able to oxidize cyclohexane into cyclohexanol and cyclohexanone with low to moderate yields. Adipic acid was also formed in the reaction. The highest conversion was obtained with the system [Cu(phen)2Cl]Cl/H2O2/70 °C. with 67% total yield. Furthermore, these complexes were also able to oxidize toluene at room temperature.

A heparin-binding hemagglutinin (HBHA) expressed on the surface of Mycobacterium tuberculosis is an antigenic protein that has been implicated in bacterial adherence to epithelial cells and systemic dissemination. In this study, the potential role of the Mycobacterium leprae HBHA (ML-HBHA) homologue in leprosy was investigated. Initially, the in vivo expression of HBHA and its association with the M. leprae cell envelope was confirmed by immunoblotting and proteomic analysis. Mycobacterium leprae recombinant HBHA (rML-HBHA) bound to a heparin-Sepharose column, and its capacity to act as an adhesin was demonstrated in experiments showing that the exogenous addition of the protein to latex beads or to M. leprae cells promotes a dramatic increase in association with epithelial cells. Finally, serum anti-HBHA immunoglobulin G levels were investigated in individuals infected with M. leprae.

The objective of this study was to compare the floristic composition and species diversity existing in the seedbanks of forests and pastures. The seedbanks were sampled in three forest and three pastures areas in a community of smallholder farmers, in Pará state, Brazil. Seedling emergence in a glasshouse was used to quantify and identify the seeds. The total densities and diversity of the seedbanks were not significantly different among the pastures and forests, but the floristic composition was different. The herbaceous species predominated in both the pastures and the forests, but in the forest the abundance of shrub and tree was higher than herb. The seed density of several pioneer woody species was higher in the forests and the density of several herbaceous species was greater in the pastures. The influence of the forest species on the pastures and of the pastures species on the forests is a result of the initial process of human occupation and illustrates a dynamic that can lead to both the conservation of forest species and the spread of weed species. Actions should be carried out to avoid disturbance in the forests and improve biodiversity preservation in rural areas.

Context. HIP 96515 A is a double-lined spectroscopic binary included in the SACY catalog as a potential young star. It has a visual companion (CCDM 19371-5134 B, HIP 96515 B) at 8".6. If bound to the primary, the optical and infrared colors of this wide companion are consistent with those of a white dwarf. Aims. We attempt to characterize the system HIP 96515 A&B by studying each of its components. Methods. We analyzed spectroscopic and photometric observations of HIP 96515 A and its visual companion, HIP 96515 B. To confirm the system as a common proper-motion pair, we analyzed the astrometry of the components using high-angular resolution infrared observations obtained within a time span of two years, and archival astrometry. Results. The high-resolution optical spectrum of HIP 96515 A was used to derive a mass ratio, M2/M1, close to 0.9. The optical lightcurve of HIP 96515 A shows periodic variations with Porbital = 2.3456 days, revealing that HIP 96515 A is an eclipsing binary with preliminary orbital parameters of i = 89°.0 ± 0°.2, and M1 = 0.59 ± 0.03 M◦. and M2 = 0.54 ± 0.03 M◦., for the primary and secondary, respectively, at an estimated distance of 42 ± 3 pc. This is a new eclipsing binary with component masses below 0.6 M◦.. Multi-epoch observations of HIP 96515 A&B show that the system is a common proper-motion pair. The optical spectrum of HIP 96515 B is consistent with a pure helium atmosphere (DB) white dwarf. The comparison with evolutionary cooling sequence models provides Teff,wD = 19 126 ± 195 K, log gwD = 8.08, MWD/M◦. = 0.6, and a distance of ˜46 pc. The estimated WD cooling age its ˜ 100 Myr and the total age of the object (including the main-sequence phase) is ˜400 Myr. Finally, if HIP 96515 A&B are coeval, and assuming a common age of ˜400 Myr, the comparison of the masses of the eclipsing binary members with evolutionary tracks shows that they are underestimated by ˜15% and 10%, for the primary and secondary, respectively.

This paper deals with the application of smooth Karhunen-Loève decomposition (SKLD) procedure applied to random fields. The SKLD is obtained by solving a generalized eigenproblem defined by combining the covariance matrix of the random field with that of the associated time-derivative random field. The main properties of the SKLD procedure thus obtained are described and compared with the classical Karhunen--Loève decomposition. The SKLD is then applied to the responses of randomly excited vibrating systems in order to perform modal analysis. The resulting SKLD characteristics are discussed, in the case of linear vibrating systems subjected to white noise excitation, in terms of normal modes.

The main properties of the SKLD procedure thus obtained are described and compared with the classical Karhunen--Loève decomposition. The SKLD is then applied to the responses of randomly excited vibrating systems in order to perform modal analysis. The resulting SKLD characteristics are discussed, in the case of linear vibrating systems subjected to white noise excitation, in terms of normal modes.001B40F30MExcitation aléatoire; Vibration aléatoire; Mode propre; Transformation Karhunen Loeve; Approche probabiliste; Matrice covariance; Matrice aléatoire; Analyse modale; Bruit blanc; .Random excitation; Random vibration; Eigenmode; Karhunen Loeve transformation; Probabilistic approach; Covariance matrix; Random matrix; Modal analysis; White noiseExcitación aleatoria; Vibración aleatoria; Modo propio; Transformación Karhunen Loeve; Enfoque probabilista; Matriz covariancia; Matriz aleatoria; Análisis modal; Ruido blancoINIST-11530.35400018725540001009-0386491

A series of 5-aryl and 3,5-diaryl-2-amino-1,4-pyrazines and the derived imidazopyrazinones has been synthesized to study the chemical oxidative degradation of the bicyclic systems in vitro. Imidazopyrazinones mainly degraded following two independent pathways producing their precursors, namely aminopyrazines, and the corresponding amidopyrazines, respectively. Despite the fact that there is no influence of the substituent of the 3-aryl group on the ratio of the products aminopyrazine/amidopyrazine, diarylimidazopyrazinones and diarylaminopyrazines are good antioxidants in vivo. They protected against microvascular damages in ischemia/reperfusion with similar efficiencies.

La logistique américaine est la plus développée et la moins coûteuse du monde. L'utilisation de modes de transport diversifiés est un facteur essentiel pour réduire les coûts totaux en Amérique du Nord. À l'opposé, au Brésil, ces coûts sont très élevés parce que le pays dépend principalement du transport routier.

Inactivating germline mutations in phosphodiesterase 11A (PDE11A) have been implicated in adrenal tumor susceptibility. PDE11A is highly expressed in endocrine steroidogenic tissues, especially the testis, and mice with inactivated Pde11α exhibit male infertility, a known testicular germ cell tumor (TGCT) risk factor. We sequenced the PDE11A gene-coding region in 95 patients with TGCT from 64 unrelated kindreds. We identified 8 nonsynonymous substitutions in 20 patients from 15 families: four (R52T, F258Y, G291R, and V820M) were newly recognized, three (R804H, R867G, and M878V) were functional variants previously implicated in adrenal tumor predisposition, and one (Y727C) was a known polymorphism. We compared the frequency of these variants in our patients to unrelated controls that had been screened and found negative for any endocrine diseases: only the two previously reported variants, R804H and R867G, known to be frequent in general population, were detected in these controls. The frequency of all PDE11A-gene variants (combined) was significantly higher among patients with TGCT (P = 0.0002), present in 19% of the families of our cohort. Most variants were detected in the general population, but functional studies showed that all these mutations reduced PDE activity, and that PDE11A protein expression was decreased (or absent) in TGCT samples from carriers. This is the first demonstration of the involvement of a PDE gene in TGCT, although the cyclic AMP signaling pathway has been investigated extensively in reproductive organ function and their diseases. In conclusion, we report that PDE11A-inactivating sequence variants may modify the risk of familial and bilateral TGCT.

In conclusion, we report that PDE11A-inactivating sequence variants may modify the risk of familial and bilateral TGCT.002B02R; 002B04; 002B20B02Mutation; Génétique; Facteur risque; Bilatéral; Cancer du testicule; Tumeur germinale du testiculePathologie de l'appareil génital mâle; Pathologie du testicule; Tumeur maligne; CancerMutation; Genetics; Risk factor; Bilateral; Testicle cancer; Testicular germ cell tumorMale genital diseases; Testicular diseases; Malignant tumor; CancerMutación; Genética; Factor riesgo; Bilateral; Cáncer del testículo; Tumor germinal de testículoINIST-5088.35400018764291006009-0389452

Chromosomal rearrangements of the human MLL gene are associated with high-risk pediatric, adult and therapy-associated acute leukemias. These patients need to be identified, treated appropriately and minimal residual disease was monitored by quantitative PCR techniques. Genomic DNA was isolated from individual acute leukemia patients to identify and characterize chromosomal rearrangements involving the human MLL gene. A total of 760 MLL-rearranged biopsy samples obtained from 384 pediatric and 376 adult leukemia patients were characterized at the molecular level. The distribution of MLL breakpoints for clinical subtypes (acute lymphoblastic leukemia, acute myeloid leukemia, pediatric and adult) and fused translocation partner genes (TPGs) will be presented, including novel MLL fusion genes. Combined data of our study and recently published data revealed 104 different MLL rearrangements of which 64 TPGs are now characterized on the molecular level. Nine TPGs seem to be predominantly involved in genetic recombinations of MLL: AFF1/AF4, MLLT3/ AF9, MLLT1/ENL, MLLT10/AF10, MLLT4/AF6, ELL, EPS15/AF1P, MLLT6/AF17 and SEPT6, respectively. Moreover, we describe for the first time the genetic network of reciprocal MLL gene fusions deriving from complex rearrangements.

We report on the study of a magnetic dislocation in pure chromium. Coherent X-ray diffraction profiles obtained on the incommensurate Spin Density Wave (SDW) reflection are consistent with the presence of a dislocation of the magnetic order, embedded at a few micrometers from the surface of the sample. Beyond the specific case of magnetic dislocations in chromium, this work may open up a new method for the study of magnetic defects embedded in the bulk.

A novel multiplexing technique for angular estimation that avoids the use of switches and multiple RF chains is presented. The principle of operation is as simple as connecting cables of different electrical lengths to the antennas. The advantages are simplicity and fast measurements, which enables the study of time-variant channels. If the duration of the excitation signal is less than a certain limit (which depends on the delays introduced by cables and on the delay spread of the propagation channel), the technique performs a time-domain multiplexing. However, the technique is especially interesting in the case that the excitation signal duration exceeds this limit. In that case, it requires the frequency of the signal to increase or to decrease linearly in time, regardless if the variation is discrete or continuous in time. The post-processing of the receiver output used to separate the signals corresponding to each antenna is detailed in this study. Once separated, the signals can be processed with a high-resolution algorithm to estimate the direction of departure and the direction of arrival. To validate the capability of this method, simulation results and measurements in an anechoic chamber are presented.

Background Recently, there has been an increase in the incidence of cutaneous leishmaniasis (CL), which represents an important health problem. This increase may be related to the epidemiologic expansion of the infective agent and the increase in tourism in tropical areas. The difficulty in clinical diagnosis, mainly in areas in which CL is not the first consideration of local physicians, has intensified efforts to describe diagnostic tests, which should be specific, sensitive, and practical. Amongst the new tests described are those including nucleic acid amplification (polymerase chain reaction, PCR) and immunohistochemistry (IHC). Methods In this study, we evaluated the sensitivity of a PCR based on small subunit (SSU) ribosomal DNA, in comparison with IHC using Leishmania spp. antibodies, in biopsies embedded in paraffin. Result The results indicated a total sensitivity of 96% (90.9% with PCR and 68.8% with IHC), showing the possibility of using paraffin-embedded biopsies to diagnose CL. Conclusion We propose the use of the two tests together as a routine protocol for diagnosis. This would require the provision of local medical services to perform molecular biology techniques and adequate Leishmania antibodies.

The relatively large number of nearby radio-quiet and thermally emitting isolated neutron stars (INSs) discovered in the ROSAT All-Sky Survey, dubbed the "Magnificent Seven", suggests that they belong to a formerly neglected major component of the overall INS population. So far, attempts to discover similar INSs beyond the solar vicinity failed to confirm any reliable candidate. The good positional accuracy and soft X-ray sensitivity of the EPIC cameras onboard the XMM-Newton satellite allow us to efficiently search for new thermally emitting INSs. We used the 2XMMp catalogue to select sources with no catalogued candidate counterparts and with X-ray spectra similar to those of the Magnificent Seven, but seen at greater distances and thus undergoing higher interstellar absorptions. Identifications in more than 170 astronomical catalogues and visual screening allowed us to select fewer than 30 good INS candidates. In order to rule out alternative identifications, we obtained deep ESO-VLT and SOAR optical imaging for the X-ray brightest candidates. We report here on the optical follow-up results of our search and discuss the possible nature of 8 of our candidates. A high X-ray-to-optical flux ratio together with a stable flux and soft X-ray spectrum make the brightest source of our sample, 2XMM J104608.7-594306, a newly discovered thermally emitting INS. The X-ray source 2XMM J010642.3+005032 has no evident optical counterpart and should be further investigated. The remaining X-ray sources are most probably identified with cataclysmic variables and active galactic nuclei, as inferred from the colours and flux ratios of their likely optical counterparts. Beyond the finding of new thermally emitting INSs, our study aims at constraining the space density of this Galactic population at great distances and at determining whether their apparently high density is a local anomaly or not.

OBJECTIVES To examine the accuracy of the World Health Organization immunological criteria for virological failure of antiretroviral treatment. METHODS Analysis of 10 treatment programmes in Africa and South America that monitor both CD4 cell counts and HIV-1 viral load. Adult patients with at least two CD4 counts and viral load measurements between month 6 and 18 after starting a non-nucleoside reverse transcriptase inhibitor-based regimen were included. WHO immunological criteria include CD4 counts persistently <100 cells/μl, a fall below the baseline CD4 count, or a fall of >50% from the peak value. Virological failure was defined as two measurements >10 0000 copies/ml (higher threshold) or ≥500 copies/ml (lower threshold). Measures of accuracy with exact binomial 95% confidence intervals (CI) were calculated. RESULTS A total of 2009 patients were included. During 1856 person-years of follow up 63 patients met the immunological criteria and 35 patients (higher threshold) and 95 patients (lower threshold) met the virological criteria. Sensitivity [95% confidence interval (CI)] was 17.1% (6.6-33.6%) for the higher and 12.6% (6.7-21.0%) for the lower threshold. Corresponding results for specificity were 97.1% (96.3-97.8%) and 97.3% (96.5-98.0%), for positive predictive value 9.5% (3.6-19.6%) and 19.0% (10.2-30.9%) and for negative predictive value 98.5% (97.9-99.0%) and 95.7% (94.7-96.6%). CONCLUSIONS The positive predictive value of the WHO immunological criteria for virological failure of antiretroviral treatment in resource-limited settings is poor, but the negative predictive value is high. Immunological criteria are more appropriate for ruling out than for ruling in virological failure in resource-limited settings.

Single phase polycrystalline thin films of multiferroic BiMn2O5 have been prepared on an LaAl03 (LAO) substrate using the pulsed laser deposition technique. X-ray diffraction and Raman scattering data show that the films are highly strained and have a single phase orthorhombic structure. Near edge x-ray absorption fine structure data of the O K-edge and the Mn L3,2-edge show no change in the electronic structure and the valence state of the BiMn2O5 thin films from that of the bulk. However, magnetic measurements performed over a wide range of temperature (2-300 K) and field (0-2 T) demonstrate a spectacular change in the magnetic behaviour of the BiMn2O5 thin films compared with the bulk. The zero field cooled magnetization confirms the antiferromagnetic transition, similar to the bulk sample, whereas field cooled magnetization data, surprisingly, show spin glass (SG) behaviour. The antiferromagnetic ordering at low temperature (5 K) is confirmed from M-H hysteresis measurements. Atomic force microscopy (AFM) measurement used to study the surface morphology shows unevenly spaced patterns of size ∼ 1-2 μm, separated by ridges of peak-to-valley height ∼40 nm. The observed magnetic behaviour is explained in the context of the highly strained structure of the films as observed by XRD, Raman scattering and AFM data.

The paper discusses the availability of biomass in Brazil to supply charcoal to the steel industry on the bases of an initial global assessment of land potentially available for plantations and of Brazilian data that allows refining the assessment and specifying the issue of practical availability. Technical potentials are first assessed through a series of simple rules against direct competition with agriculture, forests and protected areas, and of quantitative criteria, whether geo-climatic (rainfall), demographic (population density) or legal (reserves). Institutional, social and economic factors are then identified and discussed so as to account for the practical availability of Brazilian biomass through six criteria. The ranking of nine Brazilian States according to these criteria brings out the necessary trade-offs in the selection of land for plantations that would efficiently supply charcoal to the steel industry.

The integration to steady state of many initial value ODEs and PDEs using the forward Euler method can alternatively be considered as gradient descent for an associated minimization problem. Greedy algorithms such as steepest descent for determining the step size are as slow to reach steady state as is forward Euler integration with the best uniform step size. But other, much faster methods using bolder step size selection exist. Various alternatives are investigated from both theoretical and practical points of view. The steepest descent method is also known for the regularizing or smoothing effect that the first few steps have for certain inverse problems, amounting to a finite time regularization. We further investigate the retention of this property using the faster gradient descent variants in the context of two applications. When the combination of regularization and accuracy demands more than a dozen or so steepest descent steps, the alternatives offer an advantage, even though (indeed because) the absolute stability limit of forward Euler is carefully yet severely violated.

The first generation anionic iron(III) porphyrin [Fe(TSPP)] and the second generation anionic complexes [Fe(TDFSPP)], [Fe(TCFSPP)], and [Fe(TDCSPP)] were immobilized into three-dimensionally macroporous layered double hydroxide (3DM-LDH), using the direct reconstruction of 3DM-LDH from macroporous mixed oxides MOX or the anionic exchange on DDS intercalated 3DM-LDH. The macroporous layered double hydroxides were obtained at the surface of nanometric polystyrene spheres, which were synthesized by an inverse opal method. Polystyrene was removed after calcination in oxidizing atmosphere, nanostructured mixed oxides (3DM-MOX)were obtained,which after reconstruction give origin to macroporous layered double hydroxide (3DM-LDH). Following metalloporphyrin immobilization, the resulting materials were characterized by powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), UV-vis (glycerin mull) spectroscopy, attenuated total reflectance Fourier transform infrared spectroscopy (ATR/FTIR), and electron paramagnetic resonance (EPR). Results revealed that the complexes are either immobilized at the surface of the macroporous layered double hydroxide or intercalated between the layers, displacing some dodecylsufate anions. The obtained materials were investigated as catalysts for oxidation reactions, to find out whether they function as cytochrome P-450 models.

A, Chemical; ISSN 1381-1169; Pays-Bas; Da. 2009; Vol. 310; No. 1-2; Pp. 42-50; Bibl. 86 ref.AnglaisThe first generation anionic iron(III) porphyrin [Fe(TSPP)] and the second generation anionic complexes [Fe(TDFSPP)], [Fe(TCFSPP)], and [Fe(TDCSPP)] were immobilized into three-dimensionally macroporous layered double hydroxide (3DM-LDH), using the direct reconstruction of 3DM-LDH from macroporous mixed oxides MOX or the anionic exchange on DDS intercalated 3DM-LDH. The macroporous layered double hydroxides were obtained at the surface of nanometric polystyrene spheres, which were synthesized by an inverse opal method. Polystyrene was removed after calcination in oxidizing atmosphere, nanostructured mixed oxides (3DM-MOX)were obtained,which after reconstruction give origin to macroporous layered double hydroxide (3DM-LDH).

Cellulose cassava bagasse nanofibrils (CBN) were directly extracted from a by-product of the cassava starch (CS) industry, viz. the cassava bagasse (CB). The morphological structure of the ensuing nanoparticles was investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM), atomic force microscopy (AFM), presence of other components such as sugars by high performance liquid chromatography (HPLC), thermogravimetric analysis (TGA), and X-ray diffraction (XRD) experiments. The resulting nanofibrils display a relatively low crystallinity and were found to be around 2-11 nm thick and 360-1700 nm long. These nanofibrils were used as reinforcing nanoparticles in a thermoplastic cassava starch matrix plasticized using either glycerol or a mixture of glycerol/sorbitol (1:1 ) as plasticizer. Nano-composite films were prepared by a melting process. The reinforcing effect of the filler evaluated by dynamical mechanical tests (DMA) and tensile tests was found to depend on the nature of the plasticizer employed. Thus, for the glycerol-plasticized matrix-based composites, it was limited especially due to additional plasticization by sugars originating from starch hydrolysis during the acid extraction. This effect was evidenced by the reduction of glass vitreous temperature of starch after the incorporation of nanofibrils in TPSG and by the increase of elongation at break in tensile test. On the other hand, for glycerol/sorbitol plasticized nanocomposites the transcrystallization of amylopectin in nanofibrils surface hindered good performances of CBN as reinforcing agent for thermoplastic cassava starch. The incorporation of cassava bagasse cellulose nanofibrils in the thermoplastic starch matrices has resulted in a decrease of its hydrophilic character especially for glycerol plasticized sample.

Nous avons examiné l'impact de l'utilisation traditionnelle de la terre par les Amérindiens Wayanas de Guyane Française en utilisant les fourmis comme bio-indicateurs. Ces fourmis ont été capturées grâce à une méthode d'échantillonnage rapide et les résultats analysés au moyen de cartes auto-organisatrices de Kohonen (SOM). Nous avons échantillonné: (1) le village Wayana; (2) une plantation de manioc; (3) une plantation abandonnée depuis 6 ans; (4) un fragment de forêt près du village; (5) une ripisylve ; et (6) une forêt primaire. La diversité des fourmis décroît en fonction du degré de perturbation de l'habitat. Le SOM permet de suivre la succession écologique entre les six habitats. Le protocole utilisé est robuste car les mêmes conclusions sont atteintes après contrôle utilisant une information fragmentaire.

BACKGROUND: In patients with chronic-phase chronic myeloid leukemia (CP-CML), imatinib resistance is of increasing importance. Imatinib dose escalation was the main treatment option before dasatinib, which has 325-fold more potent inhibition than imatinib against unmutated Bcr-Abl in vitro. Data with a minimum of 2 years of follow-up were available for the current study of dasatinib and high-dose imatinib in CP-CML resistant to imatinib at daily doses from 400 mg to 600 mg. METHODS: A phase 2, open-label study was initiated of 150 patients with imatinib-resistant CP-CML who were randomized (2:1) to receive either dasatinib 70 mg twice daily (n = 101) or high-dose imatinib 800 mg (400 mg twice daily; n = 49). RESULTS: At a minimum follow-up of 2 years, dasatinib demonstrated higher rates of complete hematologic response (93% vs 82%; P = .034), major cytogenetic response (MCyR) (53% vs 33%; P=.017), and complete cytogenetic response (44% vs 18%; P =.0025). At 18 months, the MCyR was maintained in 90% of patients on the dasatinib arm and in 74% of patients on the high-dose imatinib arm. Major molecular response rates also were more frequent with dasatinib than with high-dose imatinib (29% vs 12%; P = .028). The estimated progression-free survival also favored dasatinib (unstratified log-rank test; P =.0012). CONCLUSIONS: After 2 years of follow-up, dasatinib demonstrated durable responses and improved response and progression-free survival rates relative to high-dose imatinib.

Imatinib dose escalation was the main treatment option before dasatinib, which has 325-fold more potent inhibition than imatinib against unmutated Bcr-Abl in vitro. Data with a minimum of 2 years of follow-up were available for the current study of dasatinib and high-dose imatinib in CP-CML resistant to imatinib at daily doses from 400 mg to 600 mg. METHODS: A phase 2, open-label study was initiated of 150 patients with imatinib-resistant CP-CML who were randomized (2:1) to receive either dasatinib 70 mg twice daily (n = 101) or high-dose imatinib 800 mg (400 mg twice daily; n = 49). RESULTS: At a minimum follow-up of 2 years, dasatinib demonstrated higher rates of complete hematologic response (93% vs 82%; P = .034), major cytogenetic response (MCyR) (53% vs 33%; P=.017), and complete cytogenetic response (44% vs 18%; P =.0025). At 18 months, the MCyR was maintained in 90% of patients on the dasatinib arm and in 74% of patients on the high-dose imatinib arm. Major molecular response rates also were more frequent with dasatinib than with high-dose imatinib (29% vs 12%; P = .028). The estimated progression-free survival also favored dasatinib (unstratified log-rank test; P =.0012). CONCLUSIONS: After 2 years of follow-up, dasatinib demonstrated durable responses and improved response and progression-free survival rates relative to high-dose imatinib.002B04; 002B19BDasatinib; Anticancéreux; Dose forte; Imatinib; Protein-tyrosine kinase; Inhibiteur enzyme; Essai clinique phase II; Leucémie myéloïde chronique; Résistance traitement; Etude longitudinale; Randomisation; CancérologieTransferases; Enzyme; Inhibiteur de la tyrosine kinase; Inhibiteur multikinase; Hémopathie maligne; Cancer; Syndrome myéloprolifératifDasatinib; Antineoplastic agent; High dose; Imatinib; Protein-tyrosine kinase; Enzyme inhibitor; Phase II trial; Chronic myelogenous leukemia; Treatment resistance; Follow up study; Randomization; CancerologyTransferases; Enzyme; Tyrosine kinase inhibitor; Multikinase inhibitor; Malignant hemopathy; Cancer; Myeloproliferative syndromeDasatinib; Anticanceroso; Dosis fuerte; Imatinib; Protein-tyrosine kinase; Inhibidor enzima; Ensayo clínico fase II; Leucemia mieloidea crónica; Resistencia tratamiento; Estudio longitudinal; Aleatorización; CancerologíaINIST-2701.35400017109027012009-0402349

Cover crops in direct seeding mulch-based cropping (DMC) systems can be an effective tool to optimize N management for crop production in the Brazilian cerrados. The objective of this study was to determine the effect of four cover crops on maize (Zea mays L.) grain yields in two fields that had been under DMC for 3 and 14 yr. We hypothesized that cover crops would optimize N supply to the maize crop, thereby leading to increased yields. Cover crop treatments were: bare fallow (BF), pigeon pea (PP) [Cajanus cajan (L.) Huth], pearl millet [Pennisetum glaucum (L.) R. Br.]-Congo signal grass (PM-CS) (Brachiaria ruziziensis Germain & Evrard), pigeon pea-finger millet (PP-FM) [Eleusine coracana (L.) Gaertn.], and sorghum (S) [Sorghum bicolor (L.) Moench]. Experiments were conducted during the 2003-2004 and 2004-2005 growing seasons. In 2003-2004 on the DMC-14 field, cover crops increased N uptake of zero-N fertilized maize with 25 to 66 kg N ha-1 compared to BF, which resulted in an increase in grain yield of 0.4 to 2.4 Mg ha-1. Effects on fertilized maize were much less. The highest yield benefits were obtained with pigeon pea and sorghum as sole cover crop. No significant cover crop effects were recorded in 2004-2005. Nitrogen losses under maize estimated on the basis of a simple soil mineral nitrogen balance ranged from 40 to 90 kg N ha-1 in 2003-2004, while they were smaller in 2004-2005 (10-25 kg N ha-1), presumably due to the lower rainfall. Cover crops can have an immediate positive effect on maize productivity under DMC in the cerrados, provided that they are sown immediately after harvest of the main crop.

The surface of ramie cellulose whiskers has been chemically modified by grafting organic acid chlorides presenting different lengths of the aliphatic chain by an esterification reaction. The occurrence of the chemical modification was evaluated by FTIR and X-ray photoelectron spectroscopies, elemental analysis and contact angle measurements. The crystallinity of the particles was not altered by the chain grafting, but it was shown that covalently grafted chains were able to crystallize at the cellulose surface when using C18. Both unmodified and functionalized nanoparticles were extruded with low density polyethylene to prepare nanocomposite materials. The homogeneity of the ensuing nanocomposites was found to increase with the length of the grafted chains. The thermomechanical properties of processed nanocomposites were studied by differential scanning calorimetry (DSC), dynamical mechanical analysis (DMA) and tensile tests. A significant improvement in terms of elongation at break was observed when sufficiently long chains were grafted on the surface of the nanoparticles. It was ascribed to improved dispersion of the nanoparticles within the LDPE matrix.

Territorial governance has become a major issue for public authorities. Studying the information generated by implementing sustainable agricultural contracts (SAC) on Reunion Island (Île de la Réunion) has contributed to the development of new types of territorial governance projects. The surveys conducted with rural development actors have revealed that learning was significant both at the individual and collective levels. This mainly involves organisational learning processes. The SAC toot has been used for developing a new type of governance, by coordinating actors with different interests and logics. This process has developed the practical and organisational practices of actors. But it has not modified their values (common project) or the development model. Thus, we believe that in order to promote 'dual loop' learning, implementing a local project is essential as it gives a meaning to the actions being carried out.

Studying the information generated by implementing sustainable agricultural contracts (SAC) on Reunion Island (Île de la Réunion) has contributed to the development of new types of territorial governance projects. The surveys conducted with rural development actors have revealed that learning was significant both at the individual and collective levels. This mainly involves organisational learning processes. The SAC toot has been used for developing a new type of governance, by coordinating actors with different interests and logics. This process has developed the practical and organisational practices of actors. But it has not modified their values (common project) or the development model. Thus, we believe that in order to promote 'dual loop' learning, implementing a local project is essential as it gives a meaning to the actions being carried out. As a result, the governance process would be reinforced.002A14D06002A32C01B1Apprentissage01Learning01Aprendizaje01Gouvernance02Governance02Gobernanza02Ile RéunionNG03Reunion islandNG03Isla ReuniónNG03Modèle04Models04Modelo04Milieu rural05Rural environment05Medio rural05Agriculture06Agriculture06Agricultura06Développement durable07Sustainable development07Desarrollo sostenible07Iles Océan IndienNGIndian Ocean IslandsNGIslas Océano IndicoNG292OTOOTOPASCAL 09-0406136 INISTWhat connection is there between the learning process and territorial governance?

Meloidogyne incognita is a nematode responsible for huge losses of economically important crops. The control of this pathogen is heavily centered on chemical nematicides, which are toxic to humans and environment, besides being very expensive. Alternatively, resistant varieties of cotton generated from conventional breeding programs represent an attractive strategy for the control of M. incognita. In this context, the goal of the work reported here was to analyze the gene expression profile of one resistant and one susceptible cotton genotype infected with M. incognita aiming to understand the mechanisms involved in resistance. EST libraries of cotton in both resistant and susceptible to infection by M. incognita were constructed and sequenced, generating 2261 sequences that were assembled into 233 contigs and 1593 singlets. Genes differentially expressed were observed in both resistant and susceptible cotton. Twenty genes were found to be expressed exclusively in the resistant cotton genotype, with functions related to pathogen recognition, signal transduction, defense mechanisms and protein synthesis transport and activation. The coordinated action of these genes suggests the existence of a complex defense pathway towards nematode attack in cotton. Our data indicate some candidate genes for validation and use through transformation in other agronomically important plants.

In the semi-arid Brazilian Northeast, the exploitation of alluvial aquifers for irrigation and domestic supply to rural communities over the last 10 years has upset the traditional mechanisms of water resources management. In the Forquilha watershed (221 km2 ; 5°17"S, 39°30"W), the two main water resources are reservoirs (with a capacity exceeding 0.9-6.7 x 106 m3), used for domestic water supply only, and an alluvial aquifer (2.3 x 106 m3), used for irrigation and domestic water supply. From 1998 to 2006, the irrigated area with alluvial groundwater increased from 0 to 75 ha, and the fraction of population supplied through domestic water networks, using reservoirs and the aquifer, increased from 1% to 70%. Based on physical and socioeconomic issues, three main water territories have been defined ("Aquifer", "Reservoirs", and "Disperse Habitat"). Considering the next 30 years with a realistic population growth, three hypotheses regarding irrigated area (i.e., 0, 75, or 150 ha), and several possible water-management scenarios, hydrological balance models were built and used to simulate the different impacts on water resource availability and salinity. Simulation results showed that, in all cases, releases from the upstream main reservoir are necessary to keep reservoir salinity below 0.7 g L-1 and for guaranteeing domestic needs in the whole watershed. As a consequence, a management approach that takes into account the interrelations among the three territories is necessary. Moreover, the simulations showed that the area of irrigated fields cannot exceed the current extent (75 ha), or serious restrictions on water availability and salinity will take place. Moreover, important socioeconomic problems are expected, including a high cost of palliative water supply with tank trucks from external sources.

Moreover, important socioeconomic problems are expected, including a high cost of palliative water supply with tank trucks from external sources.002A32C03Simulation; Multifonctionnalité; Approvisionnement eau; Bassin versant; Stratégie; Gestion eau; Gestion ressource eau; Nappe eau; Modélisation; Zone semi aride; Utilisation; Aménagement hydraulique; Ingénierie environnement; Eau disponible; Scénario (modélisation)Zone climatique; Milieu arideSimulation; Multifunctionality; Water supply; Watershed; Strategy; Water management; Water resource management; Aquifers; Modeling; Semi arid zone; Use; Water engineering; Environmental engineering; Water availability; Scenario (modeling)Climatic zone; Arid environmentSimulación; Multifuncionalidad; Alimentación agua; Cuenca; Estrategia; Gestión del agua; Gestión recurso agua; Capa agua; Modelización; Zona semiárida; Uso; Aprovechamiento hidráulico; Ingeniería ambiental; Disponibilidad del agua; Scenario (modelización)INIST-15970.35400018859018001009-0408103

The objective of this study was to assess whether defence responses in coffee (Coffea arabica) were linked to a specific developmental stage of the rust fungus Hemileia vastatrix. Histological observations in compatible and incompatible high-yielding Brazilian coffee cultivars showed that the fungus produced 'pioneer' haustoria in adjacent and subsidiary stomatal cells soon after entering the stomata, followed by later developed 'secondary haustoria' which invade mesophyll cells. In the incompatible interaction between Race II and cv. Tupi, a strong and transient H2O2 generation at infection sites was detected at 39 h post inoculation (hpi) during secondary haustoria formation. In addition, clear-cut differences in defence gene expression between compatible and incompatible interactions were only observed during the secondary haustoria formation. Transcripts of the pathogenesis-related (PR) genes CaPR1b and CaPR10 accumulated to maximal levels at 39 hpi (38- and 86-fold, respectively) in the incompatible interaction, but stayed at low levels in the compatible interaction. In contrast, the CaWRKY1 gene and the CaRLK gene were only induced in the susceptible cultivar. These results indicated that the specific resistance of cv. Tupi was expressed after differentiation of the H. vastatrix secondary haustoria. Analysis showed no evidence of specific recognition of coffee rust at the pioneer haustoria stage, suggesting that haustoria components are not recognized by, or not secreted into, the subsidiary and adjacent cells of the stomata. Additionally, the present study provides new insights into the colonization process of the coffee rust fungus.

Although the majority of patients with chronic upper airway diseases have controlled symptoms during treatment, many patients have severe chronic upper airway diseases (SCUADs). SCUAD defines those patients whose symptoms are inadequately controlled despite adequate (ie, effective, safe, and acceptable) pharmacologic treatment based on guidelines. These patients have impaired quality of life, social functioning, sleep, and school/work performance. Severe uncontrolled allergic rhinitis, nonallergic rhinitis, chronic rhinosinusitis, aspirin-exacerbated respiratory diseases, or occupational airway diseases are defined as SCUADs. Pediatric SCUADs are still unclear. In developing countries SCUADs exist, but risk factors can differ from those seen in developed countries. Comorbidities are common in patients with SCUADs and might increase their severity. The present document is the position of a group of experts considering that SCUADs should be considered differently from mild chronic upper airway diseases. It reviews the state of the art, highlighting gaps in our knowledge, and proposes several areas for a better understanding, prevention, and management of SCUADs. This document can also serve to optimize the pharmacoeconomic evaluation of SCUADs by means of comparison with mild chronic upper airway diseases.

In this paper, a detailed study of the capacitance spectra obtained from Au/doped-polyaniline/Al structures in the frequency domain (0.05 Hz-10 MHz), and at different temperatures (150-340 K) is carried out. The capacitance spectra behavior in semiconductors can be appropriately described by using abrupt cut-off models, since they assume that the electronic gap states that can follow the ac modulation have response times varying rapidly with a certain abscissa, which is dependent on both temperature and frequency. Two models based on the abrupt cutoff concept, formerly developed to describe inorganic semiconductor devices, have been used to analyze the capacitance spectra of devices based on doped polyaniline (PANI), which is a well-known polymeric semiconductor with in-numerous potential technological applications. The application of these models allowed the determination of significant parameters, such as Debye length (≃20 nm), position of bulk Fermi level (≃320 meV) and associated density of states (≃2 x 1018 eV-1 cm-3), width of the space charge region (≃70 nm), built-in potential (≃780 meV), and the gap states' distribution.

We aimed to evaluate the prognostic significance of traditional clinical predictors in osteosarcoma through an international collaboration of 10 teams of investigators (2680 patients) who participated. In multivariate models the mortality risk increased with older age, presence of metastatic disease at diagnosis, development of local recurrence when the patient was first seen, use of amputation instead of limb salvage/wide resection, employment of unusual treatments, use of chemotherapeutic regimens other than anthracycline and platinum and use of methotrexate. It was also influenced by the site of the tumour. The risk of metastasis increased when metastatic disease was present at the time the patient was first seen and also increased with use of amputation or unusual treatment combinations or chemotherapy regimens not including anthracycline and platinum. Local recurrence risk was higher in older patients, in those who had local recurrence when first seen and when no anthracycline and platinum were used in chemotherapy. Results were similar when limited to patients seen after 1990 and treated with surgery plus combination chemotherapy. This large-scale international collaboration identifies strong predictors of major clinical outcomes in osteosarcoma.

Rationale: Advances in spirometry measurement techniques have made it possible to obtain measurements in children as young as 3 years of age; however, in practice, application remains limited by the lack of appropriate reference data for young children, which are often based on limited population-specific samples. Objectives: We aimed to build on previous models by collating existing reference data in young children (aged 3-7 yr), to produce updated prediction equations that span the preschool years and that are also linked to established reference equations for older children and adults. Methods: The Asthma UK Collaborative Initiative was established to collate lung function data from healthy young children aged 3 to 7 years. Collaborators included researchers with access to pulmonary function test data in healthy preschool children. Spirometry centiles were created using the LMS (λ, μ, σ) method and extend previously published equations down to 3 years of age. Measurements and Main Results The Asthma UK centile charts for spirometry are based on the largest sample of healthy young Caucasian children aged 3-7 years (n = 3,777) from 15 centers across 11 countries and provide a continuous reference with a smooth transition into adolescence and adulthood. These equations improve existing pediatric equations by considering the between-subject variability to define a more appropriate age-dependent lower limit of normal. The collated data set reflects a variety of equipment, measurement protocols, and population characteristics and may be generalizable across different populations. Conclusions: We present prediction equations for spirometry for preschool children and provide a foundation that will facilitate continued updating.

We examined the influence of land use change, tillage system and soil texture on organic carbon (C) stocks and on organic matter composition of tropical and subtropical soils from Brazil at four long-term experiments (11-25 years) based on fine- and coarse-textured soils. Soil samples were collected from the 0-5, 5-10 and 10-20 cm layers of conventional tillage (CT) and no-till (NT) plots, and of the adjoining soil under native vegetation (NV) of Cerrado (tropical) or grassland (subtropical). Conversion of NV to CT resulted in losses of 7-29% of the original C stock of 0-20 cm; conversion to NT increased this C stock by 0-12% compared with CT. Organic matter composition of the 0-5 cm layer, assessed by solid state CPMAS-13C-NMR, ESR and laser induced fluorescence spectroscopies, was affected by land use and tillage systems. Conversion of NV to CT decreased O-alkyl and increased aromatic, carbonyl, aromatic/O-alkyl ratio, free radicals concentration and fluorescence signal. The opposite trend was observed when NT replaced CT. The relative losses and gains of C and qualitative changes resulting from land use and tillage were less evident in fine- than in coarse-textured soils, suggesting a greater resistance and a smaller resilience of fine- compared with coarse-textured soils. The direct relation between increase in C stock and increase in potentially labile moieties (e.g. O-alkyl) and the decrease in more recalcitrant moieties (e.g. aromatics) in NT soils suggests that spatial inaccessibility by aggregates is playing a major role, compared with selective preservation, in promoting C accumulation in NT soils.

To further understand the impact of tillage on carbon dioxide (CO2) emission, we compare the performance of two conceptual models that describe CO2 emission after tillage as a function of the non-tilled emission plus a correction resulting from the tillage disturbance. The models assume that C in the readily decomposable organic matter follows a first-order reaction kinetics equation as dCson(t)/dt = - kCsoil(t) and that soil C-CO2 emission is proportional to the C decay rate in soil, where Csoil(t) is the available labile soil C (g m-2) at any time (t) and k is the decay constant (time-1). Two possible relationships are derived between non-tilled (FNT) and tilled (FT) soil fluxes: FT = FNT + a1 e-a2t(model 1) and FT = a3FNT e-a4t (model 2), where t is time after tillage. The difference between these two models comes from an assumption related to the k factor of labile C in the tilled plot and its similarity to the k factor of labile C in the non-till plot. Statistical fit of experimental data to conceptual models showed good agreement between predicted and observed CO2 fluxes based on the index of agreement (d-index) and with model efficiency as large as 0.97. Comparisons reveal that model 2, where all C pools are assigned the same k factor, produces a better statistical fit than model 1. The advantage of this modelling approach is that temporal variability of tillage-induced emissions can be described by a simple analytical function that includes the non-tilled emission plus an exponential term, which is dependent upon tillage and environmental conditions.

Two hundred fifty-seven nalidixic acid-resistant enterobacterial isolates were collected in a Brazilian community from January 2000 to May 2005 to determine the prevalence of plasmid-encoded extended-spectrum β-lactamases. The blaCTX-M genetic environment was determined by polymerase chain reaction and sequencing. Eleven isolates (4.2%) harbored a blaCTX-M-2 gene, 3 isolates blaCTX-M-9, 2 isolates blaCTX-M-8, and 6 isolates blaSHV-5. Two novel blaCTX-M-2 variants, namely, blaCTX-M-74 and blaCTX-M-75, were identified.

Aims In acute coronary syndromes (ACS), the optimal revascularization strategy for unprotected left main coronary disease (ULMCD) has been little studied. The objectives of the present study were to describe the practice of ULMCD revascularization in ACS patients and its evolution over an 8-year period, analyse the prognosis of this population and determine the effect of revascularization on outcome. Methods Of 43 018 patients enrolled in the Global Registry of Acute Coronary Events (GRACE) between 2000 and 2007, and results 1799 had significant ULMCD and underwent percutaneous coronary intervention (PCI) alone (n = 514), coronary artery bypass graft (CABG) alone (n = 612), or no revascularization (n = 673). Mortality was 7.7% in hospital and 14% at 6 months. Over the 8-year study, the GRACE risk score remained constant, but there was a steady shift to more PCI than CABG over time. Patients undergoing PCI presented more frequently with ST-segment elevation myocardial infarction (STEMI), after cardiac arrest, or in cardiogenic shock; 48% of PCI patients underwent revascularization on the day of admission vs. 5.1 % in the CABG group. After adjustment, revascularization was associated with an early hazard of hospital death vs. no revascularization, significant for PCI (hazard ratio (HR) 2.60, 95% confidence interval (CI) 1.62-4.18) but not for CABG (1.26, 0.72-2.22). From discharge to 6 months, both PCI (HR 0.45, 95% Cl 0.23-0.85) and CABG (0.11, 0.04-0.28) were significantly associated with improved survival in comparison with an initial strategy of no revascularization. Coronary artery bypass graft revascularization was associated with a five-fold increase in stroke compared with the other two groups. Conclusion Unprotected left main coronary disease in ACS is associated with high mortality, especially in patients with STEMI and/or haemodynamic or arrhythmic instability. Percutaneous coronary intervention is now the most common revascularization strategy and preferred in higher risk patients. Coronary artery bypass graft is often delayed and performed in lower risk patients, leading to good 6-month survival. The two approaches therefore appear complementary.

Establishment of pine (Pinus spp.) plantations on grasslands could increase carbon (C) sequestration to counteract increased atmospheric carbon dioxide concentrations. In the grasslands of the southern Brazilian highland (Campos), large areas have been converted to Pinus plantations over the last 30 years. In order to assess the impact of this land-use change on the amount and composition of soil organic matter (SOM), we investigated a grassland pasture site (G), and both an 8-year-old (P8) and a 30-year-old (P30) plantation with Pinus taeda. Soil samples down to 45 cm were analysed for texture, pH, soil organic carbon (SOC) and total nitrogen (Ntot) concentrations. Chemical composition of SOM was determined by using cross-polarization magic angle spinning (CPMAS) 13C NMR spectroscopy. We analysed for stable C isotope (δ13C) and assessed the lignin composition by CuO oxidation. Additionally, contents of pyrogenic organic material (PyOM) were determined because the Campos is regularly burnt. Both pine plantations revealed relatively small SOC concentrations in the mineral soil of 72.6 mg g-1 (P8) and 56.8 mg g-1 (P30) and Ntot concentrations of 4.0 mg g-1 (P8) and 2.9 mg g-1 (P30) for the A horizon, while grassland showed significantly (P < 0.01) larger contents of 100.2 mg g-1 for SOC and 5.9 mg g-1 for Ntot. Accumulation of litter layers suggests decreased input of organic material into the mineral soil under pine, which was confirmed by the δ13C values and lignin composition. Smaller contents of vanillyl- (V), syringyl- (S), and cinnamyl (C)-phenols, smaller ratios of S/V and C/V, and smaller ratios of acidic to aldehydic forms of V and S phenols indicated a high degree of decomposition of residual grass-derived SOM in the upper part of the mineral soil (0-10 cm) under pine plantations. This was confirmed by CPMAS 13C NMR spectroscopy, showing an increasing Alkyl C/O-Alkyl C ratio at the same depth. No significant changes in the contents of PyOM could be detected, but all sites tended to show the greatest concentrations at deeper soil depths > 15 cm, indicating a vertical relocation of PyOM. The results suggest that decomposition of residual SOM originating from grassland species contributes to the decrease of SOC and Ntot and to an acidification in the topsoil under pine plantations. We also suggest that slow litter decomposition and incorporation and the absence of fires at the plantations are additional reasons for the reduced amount of SOM. Depletion of SOM and the acidification of the topsoil may reduce the availability and supply of nutrients and diminish the C sequestration potential of the mineral soil.

In order to assess the impact of this land-use change on the amount and composition of soil organic matter (SOM), we investigated a grassland pasture site (G), and both an 8-year-old (P8) and a 30-year-old (P30) plantation with Pinus taeda. Soil samples down to 45 cm were analysed for texture, pH, soil organic carbon (SOC) and total nitrogen (Ntot) concentrations. Chemical composition of SOM was determined by using cross-polarization magic angle spinning (CPMAS) 13C NMR spectroscopy. We analysed for stable C isotope (δ13C) and assessed the lignin composition by CuO oxidation. Additionally, contents of pyrogenic organic material (PyOM) were determined because the Campos is regularly burnt. Both pine plantations revealed relatively small SOC concentrations in the mineral soil of 72.6 mg g-1 (P8) and 56.8 mg g-1 (P30) and Ntot concentrations of 4.0 mg g-1 (P8) and 2.9 mg g-1 (P30) for the A horizon, while grassland showed significantly (P < 0.01) larger contents of 100.2 mg g-1 for SOC and 5.9 mg g-1 for Ntot. Accumulation of litter layers suggests decreased input of organic material into the mineral soil under pine, which was confirmed by the δ13C values and lignin composition. Smaller contents of vanillyl- (V), syringyl- (S), and cinnamyl (C)-phenols, smaller ratios of S/V and C/V, and smaller ratios of acidic to aldehydic forms of V and S phenols indicated a high degree of decomposition of residual grass-derived SOM in the upper part of the mineral soil (0-10 cm) under pine plantations. This was confirmed by CPMAS 13C NMR spectroscopy, showing an increasing Alkyl C/O-Alkyl C ratio at the same depth. No significant changes in the contents of PyOM could be detected, but all sites tended to show the greatest concentrations at deeper soil depths > 15 cm, indicating a vertical relocation of PyOM. The results suggest that decomposition of residual SOM originating from grassland species contributes to the decrease of SOC and Ntot and to an acidification in the topsoil under pine plantations. We also suggest that slow litter decomposition and incorporation and the absence of fires at the plantations are additional reasons for the reduced amount of SOM. Depletion of SOM and the acidification of the topsoil may reduce the availability and supply of nutrients and diminish the C sequestration potential of the mineral soil.001E01P03; 002A32B03B3; 226C03Déplétion; Diminution; Prairie; Science terre; Science du sol; Pinus taeda; Carbone organique; Azote organique; Brésil; Sol; PlantationsConiferales; Gymnospermae; Spermatophyta; Amérique du Sud; Arbre forestier résineux; Arbre forestier; Plante ligneuse; Végétal; Matière organiqueDepletion; Decrease; grasslands; Earth science; Soil science; Pinus taeda; organic carbon; Organic nitrogen; Brazil; soils; PlantationsConiferales; Gymnospermae; Spermatophyta; South America; Softwood forest tree; Forest tree; Woody plant; Vegetals; organic materialsDepleción; Disminución; Pradera; Ciencia tierra; Ciencia del suelo; Pinus taeda; Carbono orgánico; Nitrógeno orgánico; Brasil; Suelo; PlantationesINIST-2402.35400018611450005009-0414862

Physicochemical and morphological properties of açai powder produced with different carrier agents were evaluated in this work. Powders were produced by spray drying, using maltodextrin 10DE, maltodextrin 20DE, gum arabic and tapioca starch as carrier agents. Powder characterisation included analysis of moisture content, water activity, solubility, hygroscopicity, particle size distribution, morphology, total polyphenolics and antioxidant activity. Results showed that the samples produced with maltodextrin 20DE and gum arabic presented the smallest size and highest hygroscopicity. The powder produced with tapioca starch exhibited the lowest hygroscopity and solubility, and the highest mean diameter. With regard to morphology, all particles exhibited spherical and shrivelled surfaces, except those produced with tapioca starch, which exhibited rounded and smooth surfaces. Powders produced with maltodextrins and gum arabic showed high polyphenolic retention and antioxidant activity preservation after storage at 40 °C for 15 days, while for the particles produced with tapioca starch, this protective effect was less pronounced.

CADRE: Prisons de l'état de Rio de Janeiro (RJ) de haute endémicité tuberculeuse. MÉTHODES: Un dépistage radiologique de la tuberculose (TB) a été réalisé chez 1696 détenus à leur entrée dans trois prisons de RJ. La radio de thorax a été suivie d'un examen bactériologique des crachats (frottis, culture) en cas d'anomalie radiologique pulmonaire, pleurale ou médiastinale. Le diagnostic de TB a reposé sur la bactériologie ou, en cas de négativité, sur la réponse au traitement antituberculeux. RÉSULTATS: La prévalence de la TB était de 2,7%, et 32/46 cas identifiés étaient bactériologiquement confirmés, dont 19 cas par une bacilloscopie positive. Les lésions radiologiques étaient fréquemment étendues.

CONTEXTE: Dans les pays à faibles revenus, des méthodes économiques de détermination de la sensibilité de Mycobacterium tuberculosis aux antibiotiques sont nécessaires. OBJECTIF: Evaluer la méthode thin layer agar (culture sur agar en couche mince ; TLA) pour la détection rapide de la résistance à la rifampicine (RMP), à l'ofloxacine (OFX) et à la kanamycine (KM) dans des isolats cliniques de M. tuberculosis et de déterminer, par rapport à la méthode de référence, la sensibilité, la spécificité et la durée avant positivité de la méthode TLA. MÉTHODES: On a étudié 147 isolats cliniques de M. tuberculosis. Pour la méthode TLA, on a utilisé une boite de Pétri divisée en quatre quartiers préparée avec de l'agar 7H11 contenant les médicaments correspondants RMP, OFX et KM. Les résultats ont été comparés à la méthode gold standard MGIT960 pour la RMP et à la méthode des proportions sur agar 7H11 pour OFX et KM. RÉSULTATS: La sensibilité et la spécificité pour RMP et OFX ont été de 100% et pour KM, la sensibilité a été de 100% et la spécificité de 98,7%. L'utilisation de la plaque TLA divisée en quatre quartiers permet la détection rapide de la résistance de M. tuberculosis à l'égard des trois médicaments antituberculeux RMP, OFX et KM après une durée médiane de 10 jours. CONCLUSION: La TLA s'est avéré une méthode précise pour la détection de la résistance aux trois médicaments étudiés. Cette méthode plus rapide, d'emploi aisé, fournit une méthode alternative lorsque des techniques plus sophistiquées ne sont pas disponibles dans des contextes à faibles revenus.

The influence of several factors on the hydrolytic activity of lipase, present in the acetone powder from dormant castor seeds (Ricinus communis) was evaluated. The enzyme showed a marked specificity for short-chain substrates. The best reaction conditions were an acid medium, Triton X-100 as the emulsifying agent and a temperature of 30°C. The lipase activity of the acetone powder of different castor oil genotypes showed great variability and storage stability of up to 90%. The toxicology analysis of the acetone powder from genotype Nordestina BRS 149 showed a higher ricin (toxic component) content, a lower 2S albumin (allergenic compound) content, and similar allergenic potential compared with untreated seeds.

Digital cameras are now commonly included in several digital devices such as mobile phones. They are present everywhere and have become the principal image capturing tool. Inherent to light and semiconductors properties, sensor noise [10] continues to be an important factor of image quality [12], especially in low light conditions. Removing the noise with mathematical solutions appears thus unavoidable to obtain an acceptable image quality. However, embedded devices are limited by processing capabilities and power consumption and thus cannot make use of the full range of complex mathematical noise removing solutions. The bilateral filter [6] appears to be an interesting compromise between implementation complexity and noise removing performances. Especially, the Bayer [5] bilateral filter proposed in [I is well adapted for single sensor devices. In this paper, we simulate and optimize the Bayer bilateral filter execution on a common media-processor: the TM3270 [4] from the NXP Semiconductors TriMedia family. To do so we use the TriMedia Compilation System (TCS). We applied common optimization techniques (such as LUT, loop unrolling, convenient data type representation) as well as custom TriMedia operations. We finally propose a new Bayer bilateral filter formulation dedicated to the TM3270 architecture that yields an execution improvement of 99.6% compared to the naive version. This improvement results in real-time video processing at VGA resolution at the 350MHz clock rate.

Purpose Patients with visceral metastases (VM: lung and/or liver metastases) are generally regarded as being less responsive to hormonal therapy, and chemotherapy often becomes the default treatment. This paper reports a subgroup analysis from EFECT (The Evaluation of Faslodex versus Exemestane Clinical Trial) examining the efficacy of fulvestrant and exemestane in patients with or without VM. Methods EFECT is a randomised, double-blind, multicentre, Phase III trial in postmenopausal women with advanced breast cancer progressing or recurring after prior non-steroidal aromatase inhibitor therapy. Results Overall, approximately 57% of patients in EFECT had visceral involvement. Fulvestrant and exemestane demonstrated clinical benefit in 29.1% and 27.2% of patients with VM, respectively. Median duration of response was 13.5 vs 10.8 months and median duration of clinical benefit was 9.9 vs 8.1 months, respectively. Conclusions These results encourage the use of endocrine agents such as fulvestrant in treating patients with advanced breast cancer and VM.

Conclusions These results encourage the use of endocrine agents such as fulvestrant in treating patients with advanced breast cancer and VM.002B20E02Activité biologique01Biological activity01Actividad biológica01FulvestrantNKFR02FulvestrantNKFR02FulvestrantNKFR02Etude comparative03Comparative study03Estudio comparativo03ExémestaneNKFR04ExemestaneNKFR04ExemestanoNKFR04Stade avancé05Advanced stage05Estadio avanzado05Cancer du seinNM06Breast cancerNM06Cáncer del pechoNM06Homme07Human07Hombre07Malade08Patient08Enfermo08Viscère09Viscus09Víscera09Métastase10Metastasis10Metástasis10Donnée11Data11Dato11Essai clinique12Clinical trial12Ensayo clínico12Inhibiteur de l'aromatase13Aromatase inhibitor13Inhibidor aromatase13Anticancéreux23Antineoplastic agent23Anticanceroso23Antagoniste37Antagonist37Antagonista37Antihormone38Antihormone38Antihormona38Antioestrogène39Antiestrogen39Antiestrógeno39Récepteur oestrogène40Estrogen receptor40Receptor estrógeno40Dérivé de l'androstaneFR41Androstane derivativesFR41Androstano derivadoFR41Estrogen synthaseFE42Estrogen synthaseFE42Estrogen synthaseFE42EnzymeFEEnzymeFEEnzimaFEInhibiteur enzyme43Enzyme inhibitor43Inhibidor enzima43Stéroïde44Steroid44Esteroide44Tumeur maligneNM45Malignant tumorNM45Tumor malignoNM45CancerNMCancerNMCáncerNMPathologie de la glande mammaireNM46Mammary gland diseasesNM46Glándula mamaria patologíaNM46Pathologie du seinNM47Breast diseaseNM47Seno patologíaNM47Récepteur hormonal48Hormonal receptor48Receptor hormonal48Régulateur négatif sélectif du récepteur des oestrogènesINC86299OTOOTOPASCAL 09-0417699 INISTActivity of fulvestrant versus exemestane in advanced breast cancer patients with or without visceral metastases: data from the EFECT trialMAURIAC (Louis); ROMIEU (Gilles); BINES (José)Institut Bergonié, Centre Régional de Lutte Contre le Cancer de Bordeaux et du Sud-Ouest, 229 Cours de l'Argonne/33076 Bordeaux/France (1 aut.); Centre Val D'Aurelle-Paul Lamarque/Montpellier/France (2 aut.); Instituto Nacional de Câncer/Rio de Janeiro/Brésil (3 aut.)

Breast cancer research and treatment; ISSN 0167-6806; Coden BCTRD6; Pays-Bas; Da. 2009; Vol. 117; No. 1; Pp. 69-75; Bibl. 15 ref.AnglaisPurpose Patients with visceral metastases (VM: lung and/or liver metastases) are generally regarded as being less responsive to hormonal therapy, and chemotherapy often becomes the default treatment. This paper reports a subgroup analysis from EFECT (The Evaluation of Faslodex versus Exemestane Clinical Trial) examining the efficacy of fulvestrant and exemestane in patients with or without VM. Methods EFECT is a randomised, double-blind, multicentre, Phase III trial in postmenopausal women with advanced breast cancer progressing or recurring after prior non-steroidal aromatase inhibitor therapy. Results Overall, approximately 57% of patients in EFECT had visceral involvement. Fulvestrant and exemestane demonstrated clinical benefit in 29.1% and 27.2% of patients with VM, respectively. Median duration of response was 13.5 vs 10.8 months and median duration of clinical benefit was 9.9 vs 8.1 months, respectively. Conclusions These results encourage the use of endocrine agents such as fulvestrant in treating patients with advanced breast cancer and VM.002B20E02Activité biologique; Fulvestrant; Etude comparative; Exémestane; Stade avancé; Cancer du sein; Homme; Malade; Viscère; Métastase; Donnée; Essai clinique; Inhibiteur de l'aromatase; AnticancéreuxAntagoniste; Antihormone; Antioestrogène; Récepteur oestrogène; Dérivé de l'androstane; Estrogen synthase; Enzyme; Inhibiteur enzyme; Stéroïde; Tumeur maligne; Cancer; Pathologie de la glande mammaire; Pathologie du sein; Récepteur hormonal; Régulateur négatif sélectif du récepteur des oestrogènesBiological activity; Fulvestrant; Comparative study; Exemestane; Advanced stage; Breast cancer; Human; Patient; Viscus; Metastasis; Data; Clinical trial; Aromatase inhibitor; Antineoplastic agentAntagonist; Antihormone; Antiestrogen; Estrogen receptor; Androstane derivatives; Estrogen synthase; Enzyme; Enzyme inhibitor; Steroid; Malignant tumor; Cancer; Mammary gland diseases; Breast disease; Hormonal receptorActividad biológica; Fulvestrant; Estudio comparativo; Exemestano; Estadio avanzado; Cáncer del pecho; Hombre; Enfermo; Víscera; Metástasis; Dato; Ensayo clínico; Inhibidor aromatase; AnticancerosoINIST-20699.35400017197139009009-0417699

Cet article reprend et explique les concepts de thêmata et de fond topique, dans le cadre des modèles théoriques dans lesquels ils ont été définis. Son but est double: a) démontrer que ces concepts possèdent une série de caractéristiques communes et b) expliquer les raisons qui nous conduisent à concevoir l'idée de les articuler. Du point de vue du psychologue social, l'articulation thêmata-fond topique représente un grand avantage, parce qu'elle apporte au chercheur les clés qui lui permettent d'établir une correspondance entre le niveau des représentations et le niveau des lexiques. Un exemple est donné pour illustrer cette correspondance.
