La réhabilitation psychosociale a l'aube du XXIème siècle: II: Modalités thérapeutiques ou réhabilitatives et dispositif institutionnel

The main goal of psychosocial rehabilitation is to compensate the vulnerability underlying psychiatric disorders through intermediate institutions when the persistence and recurrence of these disorders have led to social and professional exclusion. Intermediate institutions refer to services which allow transition between the state of dependence on the hospital to the state of relative autonomy in social community. Psychosocial rehabilitation is a comprehensive approach which link the type of interventions: treatment, rehabilitation and support integrated in multimodal and individualized programs. A study of the out-patients followed by the rehabilitation unit of the psychiatric department in Lausanne has shown that provision of services is divided into 60% for rehabilitation, 20% for treatment and 20% for support independently of the psychiatric disorders. The implementation of these programs necessitates institutional support from psychiatric hospital to outpatient clinics through different types of facilities in order to offer a medical and psychosocial device of rehabilitation into the community

Task-dependent influence of genetic architecture and mating frequency on division of labour in social insect societies.

Division of labour is one of the most prominent features of social insects. The efficient allocation of individuals to different tasks requires dynamic adjustment in response to environmental perturbations. Theoretical models suggest that the colony-level flexibility in responding to external changes and internal perturbation may depend on the within-colony genetic diversity, which is affected by the number of breeding individuals. However, these models have not considered the genetic architecture underlying the propensity of workers to perform the various tasks. Here, we investigated how both within-colony genetic variability (stemming from variation in the number of matings by queens) and the number of genes influencing the stimulus (threshold) for a given task at which workers begin to perform that task jointly influence task allocation efficiency. We used a numerical agent-based model to investigate the situation where workers had to perform either a regulatory task or a foraging task. One hundred generations of artificial selection in populations consisting of 500 colonies revealed that an increased number of matings always improved colony performance, whatever the number of loci encoding the thresholds of the regulatory and foraging tasks. However, the beneficial effect of additional matings was particularly important when the genetic architecture of queens comprised one or a few genes for the foraging task's threshold. By contrast, a higher number of genes encoding the foraging task reduced colony performance with the detrimental effect being stronger when queens had mated with several males. Finally, the number of genes encoding the threshold for the regulatory task only had a minor effect on colony performance. Overall, our numerical experiments support the importance of mating frequency on efficiency of division of labour and also reveal complex interactions between the number of matings and genetic architecture.

Philosophie du nom et glorification du nom en Russie au début du XX ème siècle

Les glorificateurs russes du nom avancent des arguments nombreux pour affirmer une autre vision sur le mot et son origine et sur la langue en général. Ainsi la référence sur la nature divine du mot et de la langue, l'unité de la forme et du contenu, le lien étroit entre le mot et la pensée ou le sens. Ils ont voulu poser la question de l'ontologie de la langue pour éclaircir certains problèmes de son emploi. Rappelons, que cette réflexion fut entamée par les penseurs antiques, notamment par Platon et Aristote, continué aux premières décennies du christianisme, et reprise par la philosophie russe au début du XIXe siècle.

The fine-scale architecture of structural variants in 17 mouse genomes.

BACKGROUND: Accurate catalogs of structural variants (SVs) in mammalian genomes are necessary to elucidate the potential mechanisms that drive SV formation and to assess their functional impact. Next generation sequencing methods for SV detection are an advance on array-based methods, but are almost exclusively limited to four basic types: deletions, insertions, inversions and copy number gains. RESULTS: By visual inspection of 100 Mbp of genome to which next generation sequence data from 17 inbred mouse strains had been aligned, we identify and interpret 21 paired-end mapping patterns, which we validate by PCR. These paired-end mapping patterns reveal a greater diversity and complexity in SVs than previously recognized. In addition, Sanger-based sequence analysis of 4,176 breakpoints at 261 SV sites reveal additional complexity at approximately a quarter of structural variants analyzed. We find micro-deletions and micro-insertions at SV breakpoints, ranging from 1 to 107 bp, and SNPs that extend breakpoint micro-homology and may catalyze SV formation. CONCLUSIONS: An integrative approach using experimental analyses to train computational SV calling is essential for the accurate resolution of the architecture of SVs. We find considerable complexity in SV formation; about a quarter of SVs in the mouse are composed of a complex mixture of deletion, insertion, inversion and copy number gain. Computational methods can be adapted to identify most paired-end mapping patterns.

Les bisses et leurs modes d'organisation au XXIe siècle, un modèle de gestion durable ? : étude de cas à Savièse

Le décalage entre la sacralisation du principe du développement durable et la subsistance de pratiques néfastes pour l'environnement et les ressources naturelles ne va pas sans poser un certain nombre de questions sur les raisons qui expliquent cette situation; cela soulève en particulier la question de la définition exacte de ce qui peut et doit être considéré comme une exploitation durable des ressources. Dans ce contexte, ce travail se propose d'évaluer un mode de gestion dont il a été affirmé à plusieurs reprises qu'il s'agissait d'un «modèle de gestion durable»: les modes d'organisation communautaires liés à l'irrigation par les bisses, ces canaux à ciel ouvert très répandus en Valais. Notre approche, qui se situe dans la continuité des travaux sur les Régimes Institutionnels de Ressources (RIR) et repose sur une conception indéniablement forte de la durabilité, propose une grille d'analyse novatrice à travers l'assimilation des réseaux d'irrigation à des complexes multiressourciels composés des ressources eau, infrastructures (bisse) et sol. L'application rigoureuse de cette grille au cas de Savièse permet - en mettant en évidence les lacunes et les incohérences des modes de gestion qui, en 2010, sont mis en place autour du réseau encore partiellement composé de bisses - de démontrer que leur caractère durable ne va pas de soi et nécessite sans aucun doute une analyse au cas par cas.

Le théâtre de Martheray par Alexandre Perregaux (1803-1805), ou La laborieuse entreprise

De nombreux Lausannois se souviennent encore de l'ancienne chapelle de l'Eglise libre, sise à la rue Langallerie n° 5 à quelques pas du pont Bessières, avant qu'elle ne soit démolie en 1969 pour faire place à un centre commercial. Peu d'entre eux savent cependant que cet édifice fut à l'origine un théâtre, le premier théâtre en pierre construit dans le chef-lieu du Canton de Vaud, inauguré le 15 novembre 1804. L'histoire de cette salle de spectacle étant largement méconnue, notre étude souhaite retracer les circonstances de sa construction, ainsi que les principales tractations et transformations dont elle a fait l'objet, avant de fermer définitivement ses portes en 1860.

The heterotetrameric architecture of the epithelial sodium channel (ENaC).

The epithelial sodium channel (ENaC) is a key element for the maintenance of sodium balance and the regulation of blood pressure. Three homologous ENaC subunits (alpha, beta and gamma) assemble to form a highly Na+-selective channel. However, the subunit stoichiometry of ENaC has not yet been solved. Quantitative analysis of cell surface expression of ENaC alpha, beta and gamma subunits shows that they assemble according to a fixed stoichiometry, with alpha ENaC as the most abundant subunit. Functional assays based on differential sensitivities to channel blockers elicited by mutations tagging each alpha, beta and gamma subunit are consistent with a four subunit stoichiometry composed of two alpha, one beta and one gamma. Expression of concatameric cDNA constructs made of different combinations of ENaC subunits confirmed the four subunit channel stoichiometry and showed that the arrangement of the subunits around the channel pore consists of two alpha subunits separated by beta and gamma subunits.

Le déchirement. Juifs et chrétiens au premier siècle

L'antisémistisme, on le sait, tire notamment son origine de l'opprobre jetée sur les juifs par l'Eglise chrétienne au cours de ses 2000 ans d'histoire. Une chose est de reconnaître cette culpabilité, une autre est de chercher ses racines dans les textes du Nouveau Testament. C'est cette entreprise que cet ouvrage collectif effectue. Plusieurs thèses sont développées ici : - le conflit entre juifs et chrétiens est similaire aux dissensions internes au judaisme du premier siècle (F. Siegert); - l'opposition entre Jésus et les pharisiens est un conflit fratricide entre deux mouvements trop proches pour se tolérer (Ch. Tuckett); - la polémique antijuive de I Thessaloniciens 2 - « Ils (les juifs) déplaisent à Dieu et sont ennemis de tous les hommes »- est un procédé plus rhétorique que réellement polémique (E. Stegmann); - l'antijudaisme néotestamentaire le plus virulent apparaît surtout chez les auteurs judéo-chrétiens à l'enseigne d'un conflit de type familial (U. Luz).

The shared allelic architecture of adiponectin levels and coronary artery disease.

OBJECTIVE: A large body of epidemiologic data strongly suggests an association between excess adiposity and coronary artery disease (CAD). Low adiponectin levels, a hormone secreted only from adipocytes, have been associated with an increased risk of CAD in observational studies. However, these associations cannot clarify whether this relationship is causal or due to a shared set of causal factors or even confounding. Genome-wide association studies have identified common variants that influence adiponectin levels, providing valuable tools to examine the genetic relationship between adiponectin and CAD. METHODS: Using 145 genome wide significant SNPs for adiponectin from the ADIPOGen consortium (n = 49,891), we tested whether adiponectin-decreasing alleles influenced risk of CAD in the CARDIoGRAM consortium (n = 85,274). RESULTS: In single-SNP analysis, 5 variants among 145 SNPs were associated with increased risk of CAD after correcting for multiple testing (P < 4.4 × 10(-4)). Using a multi-SNP genotypic risk score to test whether adiponectin levels and CAD have a shared genetic etiology, we found that adiponectin-decreasing alleles increased risk of CAD (P = 5.4 × 10(-7)). CONCLUSION: These findings demonstrate that adiponectin levels and CAD have a shared allelic architecture and provide rationale to undertake a Mendelian randomization studies to understand if this relationship is causal.
