Calagem e diagnose foliar em sorgo sacarino (Sorghum bicolor L. moench)

Os efeitos da aplicação de cinco níveis de calcário dolomítico (0 - 1,25 - 2,50-5,00 e 10,00 t/ha) foram estudados em um Latossol Vermelho Escuro textura média. A calagem aumentou a produção de colmos de sorgo sacarino, sendo que as produções mais elevadas foram obtidas quando a soma de cálcio e magnésio, saturação em bases e valor pH do solo eram, respectivamente, 2,93 meq/100 cm³, 59% e 5,71. Foram observados desequilíbrios na nutrição potássica com a aplicação de 10 t/ha de calcário dolomítico. Os níveis críticos de Mg nas folhas + 4e + 3, coletadas, respectivamente, aos 45e 83 dias, foram 0,19 e 0,31% A qualidade do caldo não foi alterada significativamente pelas doses de calcário dolomítico empregadas.

Histoire du canon du Nouveau Testament

(Résumé de l'ouvrage) Cette Introduction informe ses lecteurs des questions essentielles abordées dans l'étude des vingt-sept livres du Nouveau Testament. Chacun d'eux fait ici l'objet d'un chapitre qui développe les rubriques suivantes : présentation littéraire de l'écrit, milieu et circonstances historiques de sa production, composition littéraire, visée théologique et indications bibliographiques. Regroupant des exégètes francophones de sensibilité protestante et catholique, cet ouvrage est devenu un manuel de référence. Pour sa 4e édition, il a été adapté à l'actualité des recherches en Nouveau Testament et offre les bibliographies les plus récentes. Un nouveau chapitre, « De Jésus aux évangiles », a également été introduit. Daniel Marguerat y aborde la période la plus obscure du premier christianisme : celle qui sépare la mort de Jésus de l'écriture du plus ancien évangile.

La Bible se raconte : initiation à l'analyse narrative

La Bible est l'un des plus fabuleux trésors d'histoires de l'humanité. Car depuis la nuit des temps, les croyants racontent. Mais pas n'importe quoi. Longuement façonnés dans l'oralité, patiemment rédigés, les récits bibliques obéissent à de subtiles règles de composition. Derrière les histoires apparemment naives se cache la fine stratégie d'un narrateur. Grâce à ses qualités pédagogiques, le livre de Daniel Marguerat et Yvan Bourquin s'est imposé comme un manuel de référence pour l'initiation à l'analyse narrative des textes bibliques. Il a été traduit en plusieurs langue. Pour cette 4e édition, l'étude de l'intrigue et de la construction des personnages a été renouvelée. Avec clarté, ses auteurs ont aménagé un parcours qui permet de découvrir les outils de l'analyse narrative, d'étudier leur application, d'évaluer leur efficacité. Toute la magie de la lecture biblique s'en trouve éclairée.

Multiple adenosine 3',5'-cyclic [corrected] monophosphate response element DNA-binding proteins generated by gene diversification and alternative exon splicing.

The protein sequence deduced from the open reading frame of a human placental cDNA encoding a cAMP-responsive enhancer (CRE)-binding protein (CREB-327) has structural features characteristic of several other transcriptional transactivator proteins including jun, fos, C/EBP, myc, and CRE-BP1. Results of Southwestern analysis of nuclear extracts from several different cell lines show that there are multiple CRE-binding proteins, which vary in size in cell lines derived from different tissues and animal species. To examine the molecular diversity of CREB-327 and related proteins at the nucleic acid level, we used labeled cDNAs from human placenta that encode two different CRE-binding proteins (CREB-327 and CRE-BP1) to probe Northern and Southern blots. Both probes hybridized to multiple fragments on Southern blots of genomic DNA from various species. Alternatively, when a human placental c-jun probe was hybridized to the same blot, a single fragment was detected in most cases, consistent with the intronless nature of the human c-jun gene. The CREB-327 probe hybridized to multiple mRNAs, derived from human placenta, ranging in size from 2-9 kilobases. In contrast, the CRE-BP1 probe identified a single 4-kilobase mRNA. Sequence analyses of several overlapping human genomic cosmid clones containing CREB-327 sequences in conjunction with polymerase chain reaction indicates that the CREB-327/341 cDNAs are composed of at least eight or nine exons, and analyses of human placental cDNAs provide direct evidence for at least one alternatively spliced exon. Analyses of mouse/hamster-human hybridoma DNAs by Southern blotting and polymerase chain reaction localizes the CREB-327/341 gene to human chromosome 2. The results indicate that there is a dichotomy of CREB-like proteins, those that are related by overall structure and DNA-binding specificity as well as those that are related by close similarities of primary sequences.

Evidence of new risk genetic factor to systemic lupus erythematosus: the UBASH3A gene

The ubiquitin associated and Src-homology 3 (SH3) domain containing A (UBASH3a) is a suppressor of T-cell receptor signaling, underscoring antigen presentation to T-cells as a critical shared mechanism of diseases pathogenesis. The aim of the present study was to determine whether the UBASH3a gene influence the susceptibility to systemic lupus erythematosus (SLE) in Caucasian populations. We evaluated five UBASH3a polymorphisms (rs2277798, rs2277800, rs9976767, rs13048049 and rs17114930), using TaqMan® allelic discrimination assays, in a discovery cohort that included 906 SLE patients and 1165 healthy controls from Spain. The SNPs that exhibit statistical significance difference were evaluated in a German replication cohort of 360 SLE patients and 379 healthy controls. The case-control analysis in the Spanish population showed a significant association between the rs9976767 and SLE (Pc = 9.9E-03 OR = 1.21 95%CI = 1.07-1.37) and a trend of association for the rs2277798 analysis (P = 0.09 OR = 0.9 95%CI = 0.79-1.02). The replication in a German cohort and the meta-analysis confirmed that the rs9976767 (Pc = 0.02; Pc = 2.4E-04, for German cohort and meta-analysis, respectively) and rs2277798 (Pc = 0.013; Pc = 4.7E-03, for German cohort and meta-analysis, respectively) UBASH3a variants are susceptibility factors for SLE. Finally, a conditional regression analysis suggested that the most likely genetic variation responsible for the association was the rs9976767 polymorphism. Our results suggest that UBASH3a gene plays a role in the susceptibility to SLE. Moreover, our study indicates that UBASH3a can be considered as a common genetic factor in autoimmune diseases.

L'exception sportive : champions noirs et culture coloniale (1900-1939)

4e de couv.: Comment la France a-t-elle été colonisée par son Empire ? En traitant du fait national tel qu'il a été modelé par l'idéologie coloniale, ce livre renverse les perspectives. Pour légitimer leurs lointaines conquêtes, la monarchie, l'empire et la république ont conçu, organisé, relayé auprès des Français une culture coloniale. Le cinéma et le théâtre, le sport et l'école, la littérature et la presse, les arts, la publicité, la chanson, sans oublier l'armée, les comités coloniaux, les expositions se sont chargés de diffuser quêtes scientifiques, fascinations exotiques, fiertés patriotiques ainsi qu'intérêts économiques et politiques. A l'heure où la France éprouve la difficulté de rassembler dans un destin commun des mémoires divisées, ce sont les grandes lignes de ce "passé qui ne passe pas" et les méandres d'une utopie coloniale que ce recueil retrace, de la première abolition de l'esclavage aux présents débats sur la "repentance". Une somme.

Cardiac raptor ablation impairs adaptive hypertrophy, alters metabolic gene expression, and causes heart failure in mice.

Background- Cardiac hypertrophy involves growth responses to a variety of stimuli triggered by increased workload. It is an independent risk factor for heart failure and sudden death. Mammalian target of rapamycin (mTOR) plays a key role in cellular growth responses by integrating growth factor and energy status signals. It is found in 2 structurally and functionally distinct multiprotein complexes called mTOR complex (mTORC) 1 and mTORC2. The role of each of these branches of mTOR signaling in the adult heart is currently unknown. Methods and Results- We generated mice with deficient myocardial mTORC1 activity by targeted ablation of raptor, which encodes an essential component of mTORC1, during adulthood. At 3 weeks after the deletion, atrial and brain natriuretic peptides and β-myosin heavy chain were strongly induced, multiple genes involved in the regulation of energy metabolism were altered, but cardiac function was normal. Function deteriorated rapidly afterward, resulting in dilated cardiomyopathy and high mortality within 6 weeks. Aortic banding-induced pathological overload resulted in severe dilated cardiomyopathy already at 1 week without a prior phase of adaptive hypertrophy. The mechanism involved a lack of adaptive cardiomyocyte growth via blunted protein synthesis capacity, as supported by reduced phosphorylation of ribosomal S6 kinase 1 and 4E-binding protein 1. In addition, reduced mitochondrial content, a shift in metabolic substrate use, and increased apoptosis and autophagy were observed. Conclusions- Our results demonstrate an essential function for mTORC1 in the heart under physiological and pathological conditions and are relevant for the understanding of disease states in which the insulin/insulin-like growth factor signaling axis is affected such as diabetes mellitus and heart failure or after cancer therapy.

A-Kinase Anchoring Protein Lbc Coordinates a p38 Activating Signaling Complex Controlling Compensatory Cardiac Hypertrophy.

In response to stress, the heart undergoes a remodeling process associated with cardiac hypertrophy that eventually leads to heart failure. A-kinase anchoring proteins (AKAPs) have been shown to coordinate numerous prohypertrophic signaling pathways in cultured cardiomyocytes. However, it remains to be established whether AKAP-based signaling complexes control cardiac hypertrophy and remodeling in vivo. In the current study, we show that AKAP-Lbc assembles a signaling complex composed of the kinases PKN, MLTK, MKK3, and p38α that mediates the activation of p38 in cardiomyocytes in response to stress signals. To address the role of this complex in cardiac remodeling, we generated transgenic mice displaying cardiomyocyte-specific overexpression of a molecular inhibitor of the interaction between AKAP-Lbc and the p38-activating module. Our results indicate that disruption of the AKAP-Lbc/p38 signaling complex inhibits compensatory cardiomyocyte hypertrophy in response to aortic banding-induced pressure overload and promotes early cardiac dysfunction associated with increased myocardial apoptosis, stress gene activation, and ventricular dilation. Attenuation of hypertrophy results from a reduced protein synthesis capacity, as indicated by decreased phosphorylation of 4E-binding protein 1 and ribosomal protein S6. These results indicate that AKAP-Lbc enhances p38-mediated hypertrophic signaling in the heart in response to abrupt increases in the afterload.

Etat de santé de la population valaisanne 2010

Sur mandat du Service de la santé publique, l'Observatoire valaisan de la santé (OVS) publie le 4e Rapport sur l'état de santé de la population valaisanne. Selon ce rapport, la population du canton bénéficie d'un très bon état de santé général. L'espérance de vie y est une des meilleures au monde. Les maladies cardiovasculaires et les cancers continuent d'être responsables de près de 2/3 des décès. Pour diminuer l'impact de ces maladies, il est nécessaire de poursuivre sur la voie d'une politique de promotion de la santé et de prévention active et ciblée. Le Conseil d'Etat a adopté un programme-cadre allant dans ce sens. Réalisé par l'OVS en collaboration avec l'Institut universitaire de médecine sociale et préventive de Lausanne (IUMSP), le rapport sur l'état de santé livre une photographie sanitaire de la population valaisanne. Il sert de document de référence au gouvernement pour définir les axes de la politique de promotion de la santé et de prévention pour les années 2011-2014.
