Des histories de famille. La dévotion aux Trois Maries en France du XIVe au XVe siècle. Textes et images

La légende des Trois Maries, les demi-soeurs nées du trinubium de sainte Anne, fut largement diffusée à partir du XIIIe siècle par la Légende dorée de Jacques de Voragine. L’émergence précoce du culte et de l’iconographie des Trois Maries à Paris, à partir du milieux du XIVe siècle, a été favorisée par la rencontre entre un miracle de guérison, en ordre religieux: les Carmes, en quête de légitimation et une reine de France: Jeanne d’Evreux, dont la descendance fut exclue de la succession au trône. L’iconographie des Trois Maries, dont Jean Venette, auteur carme, raconta l’histoire dans un long récit versifi é, est attestée dans les manuscrits et sur d’autres supports.

Mitral restenosis in the early postoperative period of a patient with systemic lupus erythematosus

A forty eight year old woman, who had undergone mitral comissurotomy and subsequently developed early restenosis, presented with major comissural fusion and verrucous lesions on the cuspid edges of the mitral valve, with normal subvalvar apparatus. Patient did well for the first six months after surgery when she began to present dyspnea on light exertion. A clinical diagnosis of restenosis was made, which was confirmed by an echocardiogram and cardiac catheterization. She underwent surgery, and a stenotic mitral valve with verrucous lesions suggesting Libman-Sacks' endocarditis was found. Because the diagnosis of systemic lupus erythematosus (SLE) had not been confirmed at that time, a bovine pericardium bioprosthesis (FISICS-INCOR) was implanted. The patient did well in the late follow-up and is now in NYHA Class I .

Pressao arterial elevada em criancas e sua correlacao com tres definicoes de obesidade infantil

FUNDAMENTO: Diversos autores correlacionaram o aumento do risco cardiovascular com o estado nutricional, porém existem diferentes critérios para a classificação de sobrepeso e obesidade em crianças. Objetivos: Avaliar o desempenho de três critérios de classificação nutricional em crianças, como definidores da presença de obesidade e preditores de níveis pressóricos elevados em escolares. MÉTODOS: Oitocentas e dezessete crianças de 6 a 13 anos matriculadas em escolas públicas do município de Vila Velha (ES) foram submetidas a avaliação antropométrica e de pressão arterial. A classificação quanto ao estado nutricional foi estabelecida mediante dois critérios internacionais (CDC/NCHS 2000 e IOTF 2000) e um critério brasileiro (Conde e Monteiro 2006). RESULTADOS: A prevalência de excesso de peso foi maior quando utilizado o critério de Conde e Monteiro (27%), e menor pelo critério do IOTF (15%). Pressão arterial elevada foi observada em 7,3% das crianças. Identificou-se forte associação entre a presença de excesso de peso e a ocorrência de níveis pressóricos elevados, independentemente do critério utilizado (p < 0,001). O critério que demonstrou maior sensibilidade em prever PA elevada foi o de Conde e Monteiro (44%), enquanto o de maior especificidade (94%), além de maior acurácia geral (63%), foi o do CDC. CONCLUSÕES: A prevalência de excesso de peso em crianças brasileiras é maior quando utilizado o critério de classificação de Conde e Monteiro, e menor quando utilizado o critério do IOTF. O critério de classificação brasileiro demonstrou ser o mais sensível como preditor de risco de PA elevada nessa amostra.

Le code-switching comme ressource stratégique pour la gestion de l'interaction multilingue : coordination et leadership dans un groupe de travail

In this article, we analyze a multilingual interaction in a students' working group and hypothesize a correlation between management of languages in interaction and leadership. We consider Codeswitching as one of the most relevant observables in multilingual interaction and attempt to analyze how it is used by speakers. After a brief presentation of three theoretical and analytical conceptions of Code-switching in interaction (Auer, Mondada & Myers Scotton), we define Code-switching as an interactional, strategical, multilingual resource exploited by speakers to achieve various interactionaland non interactional goals. We then show in two CA-like analysis how multilingual strategical resources occur in the interactional practices of the analyzed working group, and how they are exploited by speakers in order to organize interaction, work, tasks, and to construct one's leadership.We also consider the metadiscourses of the students about their own practices and multilingualism in general, in order to confront them to their actual multilingual practices. We draw the hypothesis that discrepancies observed between metadiscourses and practices can be explained through the development of (meta)discourses showing a unilingual conception in describing multilingual practices.

The imidazoline receptors and the central regulation of the arterial blood pressure: a minireview

Recently, we proposed the hypothesis according to wich the central hypotensive effect of clonidine and related substances could be related to an action upon specific receptors, requiring the imidazoline or imidazoline-like structures, rather than alpha2-adrenoceptors. Since then, direct evidences have been accumulated to confirm the existence of a population of imidazoline specific binding sites in the brainstem of animals and man, more precisely in the Nucleus Reticularis Lateralis (NRL) region of the ventrolateral medulla (VLM), site of the antihypertensive action of clonidine. The purification of the putative endogenous ligand of the imidazoline receptors - named endazoline - is currently being attempted from human brain extracts. This new concept might at last lead to the expected dissociation of the pharmacological mechanisms involved, on the one hand, in the therapeutic antihypertensive effect, and on the other, in their major side-effect, which is sedation. In fact, it has been recently confirmed that hypotension is mediated by the activation of imidazoline preferring receptors (IPR) within the NRL region, while sedation is attributed to the inhibition of alpha2-adrenergic mechanisms in the locus coeruleus, which is involved in the control of the sleep-waking cycle. The IPRmay constitute on interesting target for new drugs in the treatment of arterial hypertension. Finally, dysfunctions of this modulatory system which could be involved in the pathophysiologyof some forms of the hypertensive disease are under investigation.

Être affecté : petite phénoménologie de la « prophétie » charismatique (et de ses conséquences)

Jeanne Favret-Saada a bousculé un présupposé courant en sciences sociales faisant équivaloir le regard scientifique avec le fait d'observer le phénomène investigué depuis l'extérieur. Or, un tel régime de description peine à restituer des pratiques qui semblent exotiques, voire incroyables pour l'observateur détaché, alors qu'elles apparaissent crédibles aux acteurs sociaux. À ce point, l'engagement de l'ethnographe - jusque dans ses affects - s'avère central pour ressaisir la vraisemblance d'un monde social - sans pour autant endosser son ontologie. Cet article explore cette problématique en s'intéressant à la « prophétie » charismatique comme modalité, pour des évangéliques, de faire saillir la présence de Dieu à même leur vie et au sein du monde. Couplant une phénoménologie de l'expérience religieuse à une approche pragmatiste, on s'interrogera sur les conséquences politiques, pour la communauté nationale, de ce surgissement de la divinité.

Multilocus sequence analysis reveals the genetic diversity of European fruit tree phytoplasmas and supports the existence of inter-species recombination

The genetic diversity of three temperate fruit tree phytoplasmas ‘Candidatus Phytoplasma prunorum’, ‘Ca. P. mali’ and ‘Ca. P. pyri’ has been established by multilocus sequence analysis. Among the four genetic loci used, the genes imp and aceF distinguished 30 and 24 genotypes, respectively, and showed the highest variability. Percentage of substitution for imp ranged from 50 to 68% according to species. Percentage of substitution varied between 9 and 12% for aceF, whereas it was between 5 and 6% for pnp and secY. In the case of ‘Ca P. prunorum’ the three most prevalent aceF genotypes were detected in both plants and insect vectors, confirming that the prevalent isolates are propagated by insects. The four isolates known to be hypo-virulent had the same aceF sequence, indicating a possible monophyletic origin. Haplotype network reconstructed by eBURST revealed that among the 34 haplotypes of ‘Ca. P. prunorum’, the four hypo-virulent isolates also grouped together in the same clade. Genotyping of some Spanish and Azerbaijanese ‘Ca. P. pyri’ isolates showed that they shared some alleles with ‘Ca. P. prunorum’, supporting for the first time to our knowledge, the existence of inter-species recombination between these two species.

Monitoring de la problématique du cannabis en Suisse: étude sentinelle 2004-2009

Le monitoring de la problématique du cannabis en Suisse constitue un ensemble de travaux qui permettent le suivi de la situation au niveau national et qui sont mis en oeuvre par un consortium d'institutions de recherche. Ce monitoring comprend l'étude présentée dans ce rapport, l'étude sentinelle. Celle-ci s'intéresse à l'évolution de la situation en matière de cannabis ainsi qu'à la gestion de cette situation au niveau local. Il s'agit de répondre aux questions suivantes : - quelle est la situation en matière de consommation de cannabis et de marché et quelle est son évolution ? - quels sont les principaux problèmes rencontrés sur le terrain ? - quelles sont les mesures et interventions qui ont été développées dans ce domaine ? Pour y répondre, on a choisi de suivre la situation dans quatre cantons suisses dits "sentinelle" (St-Gall, Tessin, Vaud, Zurich). Les critères de choix de ces cantons font appel à leur taille, au rapport ville/campagne et à la présence de frontière avec des états voisins, à la langue, au type de politique drogue pratiqué. Dans chaque canton on a constitué des panels d'experts formés par des profes-sionnels de terrain dans trois domaines différents (santé et social, école, police et justice). Leurs observations ainsi que les données cantonales disponibles sont récoltées et discutées lors d'un workshop et analysées sur plusieurs années. Le présent rapport fait état des résultats des quatre workshops de suivi (2005, 2006, 2008, 2009). [Résumé, p. 5]
