Long-distance wolf recolonization of France and Switzerland inferred from non-invasive genetic sampling over a period of 10 years

In the early 1900s, the wolf (Canis lupus) was extirpated from France and Switzerland. There is growing evidence that the species is presently recolonizing these countries in the western Alps. By sequencing the mitochondrial DNA (mtDNA) control region of various samples mainly collected in the field (scats, hairs, regurgitates, blood or tissue; n = 292), we could (1) develop a non-invasive method enabling the unambiguous attribution of these samples to wolf, fox (Vulpes vulpes) or dog (Canis familiaris), among others; (2) demonstrate that Italian, French and Swiss wolves share the same mtDNA haplotype, a haplotype that has never been found in any other wolf population world-wide. Combined together, field and genetic data collected over 10 years corroborate the scenario of a natural expansion of wolves from the Italian source population. Furthermore, such a genetic approach is of conservation significance, since it has important consequences for management decisions. This first long-term report using non-invasive sampling demonstrates that long-distance dispersers are common, supporting the hypothesis that individuals may often attempt to colonize far from their native pack, even in the absence of suitable corridors across habitats characterized by intense human activities.

Etude prospective d'évaluation psychiatrique et pédagogique dans un service pour adolescents de la Fondation Santé des Etudiants de France. Méthodologie et résultats préliminaires [Prospective study of psychiatric and pedagogic evaluation of the adolescent service of the Student Health Foundation of France. Methodology and preliminary results].

The present prospective study, with a five-year follow-up, presents an extensive psychiatric and educational assessment of an adolescent population (N = 30) in the age range 14-20, suffering from several psychiatric disorders, though apt to follow a normal academic program. The residential settings where the study took place provide both psychiatric and schooling facilities. In this environment, what is the effectiveness of long-term hospitalization? Are there any criteria for predicting results? After discharge, could social adjustments difficulties be prevented? Assessment instruments are described and the results of one preliminary study are presented. The actual data seems to confirm the impact of the special treatment facilities combining schooling and psychiatric settings on the long term outcome of adolescents.

A human MYBPC3 mutation appearing about 10 centuries ago results in a hypertrophic cardiomyopathy with delayed onset, moderate evolution but with a risk of sudden death.

BACKGROUND: Hypertrophic Cardiomyopathy (HCM) is a genetically heterogeneous disease. One specific mutation in the MYBPC3 gene is highly prevalent in center east of France giving an opportunity to define the clinical profile of this specific mutation. METHODS: HCM probands were screened for mutation in the MYH7, MYBPC3, TNNT2 and TNNI3 genes. Carriers of the MYBPC3 IVS20-2A>G mutation were genotyped with 8 microsatellites flanking this gene. The age of this MYBPC3 mutation was inferred with the software ESTIAGE. The age at first symptom, diagnosis, first complication, first severe complication and the rate of sudden death were compared between carriers of the IVS20-2 mutation (group A) and carriers of all other mutations (group B) using time to event curves and log rank test. RESULTS: Out of 107 HCM probands, 45 had a single heterozygous mutation in one of the 4 tested sarcomeric genes including 9 patients with the MYBPC3 IVS20-2A>G mutation. The IVS20-2 mutation in these 9 patients and their 25 mutation carrier relatives was embedded in a common haplotype defined after genotyping 4 polymorphic markers on each side of the MYBPC3 gene. This result supports the hypothesis of a common ancestor. Furthermore, we evaluated that the mutation occurred about 47 generations ago, approximately at the 10th century.We then compared the clinical profile of the IVS20-2 mutation carriers (group A) and the carriers of all other mutations (group B). Age at onset of symptoms was similar in the 34 group A cases and the 73 group B cases but group A cases were diagnosed on average 15 years later (log rank test p = 0.022). Age of first complication and first severe complication was delayed in group A vs group B cases but the prevalence of sudden death and age at death was similar in both groups. CONCLUSION: A founder mutation arising at about the 10th century in the MYBPC3 gene accounts for 8.4% of all HCM in center east France and results in a cardiomyopathy starting late and evolving slowly but with an apparent risk of sudden death similar to other sarcomeric mutations.

Fungal co-culture as a new source of antifungal metabolites

Background: Over the last two decades, mortality from coronary heart disease (CHD) and cerebrovascular disease (CVD) declined by about 30% in the European Union (EU). Design: We analyzed trends in CHD (X ICD codes: I20-I25) and CVD (X ICD codes: I60-I69) mortality in young adults (age 35-44 years) in the EU as a whole and in 12 selected European countries, over the period 1980-2007. Methods: Data were derived from the World Health Organization mortality database. With joinpoint regression analysis, we identified significant changes in trends and estimated average annual percent changes (AAPC). Results: CHD mortality rates at ages 35-44 years have decreased in both sexes since the 1980s for most countries, except for Russia (130/100,000 men and 24/100,000 women, in 2005-7). The lowest rates (around 9/100,000 men, 2/100,000 women) were in France, Italy and Sweden. In men, the steepest declines in mortality were in the Czech Republic (AAPC = -6.1%), the Netherlands (-5.2%), Poland (-4.5%), and England and Wales (-4.5%). Patterns were similar in women, though with appreciably lower rates. The AAPC in the EU was -3.3% for men (rate = 16.6/100,000 in 2005-7) and -2.1% for women (rate = 3.5/100,000). For CVD, Russian rates in 2005-7 were 40/100,000 men and 16/100,000 women, 5 to 10-fold higher than in most western European countries. The steepest declines were in the Czech Republic and Italy for men, in Sweden and the Czech Republic for women. The AAPC in the EU was -2.5% in both sexes, with steeper declines after the mid-late 1990s (rates = 6.4/100,000 men and 4.3/100,000 women in 2005-7). Conclusions: CHD and CVD mortality steadily declined in Europe, except in Russia, whose rates were 10 to 15-fold higher than those of France, Italy or Sweden. Hungary and Poland, and also Scotland, where CHD trends were less favourable than in other western European countries, also emerge as priorities for preventive interventions.

The 19th Ion Channel Meeting. September 2008, France.

The annual meeting of the French Ion Channels Society, held on the Mediterranean coast of France, is aimed at gathering the international scientific community working on various aspects of ion channels. In this report of the 19th edition of the meeting, held in September 2008, we summarize selected symposia on aspects of the ion channel field from fundamental to clinical research. The meeting is an opportunity for leading investigators as well as young researchers to present and discuss their recent advances and future challenges in the ion channel field.

Simultaneous determination of Pu and Am radioisotopes in environmental samples: a tool for determining origin and release date

A radiochemical procedure was developed for the sequential determination of Pu and Am radioisotopes in environmental samples. The radioisotope activities were then used to assess the origin and release date of the environmental plutonium. The radioanalytical procedure is based on the separation of Pu and Am on selective extraction chromatographic resins (Eichrom TEVA and DGA). Alpha sources were prepared by electrodeposition on stainless steel discs, and the alpha emitting radionuclides (238Pu, 239,240Pu and 241Am) were measured by alpha spectrometry. For the determination of the beta emitting 241Pu, the Pu alpha source was leached in hot concentrated nitric acid and the Pu fraction further purified by extraction chromatography on a small column of TEVA resin (100 μg of resin in a pipette tip). 241Pu is then measured by ultra low level liquid scintillation counting. Due to the lack of reference material for 241Pu, the proposed radiochemical method was nevertheless validated using four IAEA reference sediments with information values of 241Pu. The proposed method was then used to determine the 238Pu, 239,240Pu, 241Pu and 241Am activity concentrations in alpine soils of France and Switzerland. The soil is the primary receptor of the atmospheric radioactive fallout and, because of the strong binding interaction with soils particles, the isotopes are little fractionated. Therefore, the activity ratios 241Pu/239+240Pu and 238Pu/239,240Pu in soil samples were used to determine the origin (source) and date of the Pu contamination in the investigated alpine sites. The 241Pu/239,240Pu and 238Pu/239,240Pu activity ratios confirmed that the main origin of Pu in the alpine soils was the global fallout from the nuclear bomb tests (NBT) in the fifties and sixties. Furthermore, the 241Pu/241Am activity ratios were used to determine the age of the Pu contamination, which is also an important data for distinguishing the Pu sources. The estimation of the date of the contamination, by the 241Pu/241Am age-dating method, further confirmed the NBT as the Pu source. However, the 241Pu/241Am dating method was limited to samples where Pu-Am fractionation was insignificant. If any, the contribution of the Chernobyl accident in the studied sites is negligible.

Coronary heart disease and cerebrovascular disease mortality in young adults: recent trends in Europe.

"Acheiro-poïétique" du cinéma: le Christ révélé par l'écran

Selon la tradition orientale, les représentations de Jésus trouveraient toutes leur origine dans les images acheiropoïètes, c'est-à-dire dans des figurations de la "Sainte Face" du Christ non faites de main d'homme, mais survenues par apparition divine -sur le voile de Véronique, le Saint Suaire, le mandylion d'Edesse, etc. Ces images qui, pour des théologiens de l'icône tels que Léonide Ouspensky, ne sont rien moins que "la manifestation du miracle fondamental : la venue du Créateur dans sa création" (in L'Image du Christ non faite de main d'homme, 1989), ont toujours été le ferment d'expérimentations multiples chez les peintres et les sculpteurs.Mais la réflexion artistique s'est cristallisée au moment où ces images sont devenues l'apanage de médiums issus de "l'ère de la reproductibilité technique" chère à Benjamin. En effet, les images "théographes" auraient pour spécificité d'être engendrées et de se multiplier par empreinte immédiate: une toile quelconque n'aurait qu'à être touchée par le visage du Christ pour devenir instantanément le support du divin portrait, et acquérir dès lors le "pouvoir reconnu aux acheiropoïètes de créer des doubles de même valeur, par simple contact" (François Boespflug, Dieu et ses images. Une histoire de l'Eternel dans l'art, 2008). Comment mieux faire écho aux principes mêmes de l'image (ciné)photographique, générée par indicialité et reproductibilité? André Bazin a eu l'intuition de cette parenté dans le cadre de sa théorisation sur le pouvoir "révélateur" de l'image (ciné)photographique qui selon lui procéderait "par sa genèse" de "l'ontologie du modèle" et "serait" le modèle; il a évoqué le Saint Suaire de Turin comme rejouant, voire emblématisant cette même "ontologie de l'image photographique" (dans l'article homonyme de 1945). Si Bazin ne développe pas plus avant ses considérations, la corrélation des dispositifs (ciné)photographique et acheiropoïète a connu un questionnement « en actes », au sein des films cherchant à représenter Jésus.Valentine Robert s'intéresse à ces expérimentations, à commencer par un projet de film d'Abel Gance de 1947, resté inachevé, où le suaire de Turin devait se transformer en écran de cinéma. Plusieurs autres productions seront abordées, telles que Civilization ou The Robe, qui explorent les effets visuels permis par la pellicule pour montrer le Christ en surimpression, dans une sorte d'"apparition technologique", ou telles que The Jesus Film ou The Passion of the Christ, dont la projection a été reçue par certains publics comme une apparition sacrée réactualisant l'Incarnation. Les modalités de la représentation des images acheiropoïètes et plus généralement de l'apparition de Jésus à l'écran seront enfin évoquées - de la tradition hollywoodiennes qui consistait à refuser l'accès de la "Sainte Face" à la pellicule et de la rejeter hors-champ jusqu'aux séquences d'Ecce Homo de Scorsese et Zeffirelli, en passant par la révélation visuelle inaugurant The King of Kings, qui pousse à son paroxysme la collusion entre apparition divine et apparition cinématographique.

Le sophiste Dion de Pruse, le bon roi et l'empereur

Cet article porte sur la réflexion politique grecque au sujet du principat et sur les relations entre le sophiste Dion de Pruse (40-50 après J.-C. - après 110 ?) et le pouvoir impérial. Il propose une analyse des discours de Dion qui concernent les modèles de royauté : les quatre discours Sur la royauté (Or. I à IV), l'Agamemnon (Or. LVI), le discours Sur la royauté et la tyrannie (Or. LXII). La première partie examine les circonstances de rédaction ou de prononciation des discours, afin de distinguer différentes étapes dans la pensée politique du sophiste et dans son jugement sur la figure de l'empereur. La deuxième partie étudie les deux images du « bon » roi : le roi imparfait, soumis à reddition de compte ; l'Optimus Princeps. Cette seconde image, beaucoup plus développée, est définie à la fois par un ensemble de vertus et par l'imitation du roi des dieux. La troisième partie analyse les objectifs de Dion, compare sa réflexion avec celles des intellectuels romains du Ier et du IIe siècles, dégage sa position complexe à l'égard du principat et de la figure de Trajan. The paper focuses on Greek political thinking on principate as well as on the relations between the sophist Dio of Prusa (40-50 till 100 A.D. ?) and the imperial power. It analyses Dion's speeches on royal models : the four speeches On Kingship (Or. I to IV), the Agamemnon (Or. LVI) as well as the speech On Kingship and Tyranny (Or. LXII). The first part examines under which circumstances these speeches have been drafted and given, in order to highlight the evolution of the sophist's political thinking and his assessment of the figure of emperor. Secondly, the two images of a good king are examined : the imperfect and accountable king on the one hand, the Optimus Princeps on the other. The latter image, more largely developed, is both defined by a collection of virtues and an imitation of the king of gods. The third and last part analyses Dion's objectives, compares his thoughts with the ones of 1st and 2nd centuries Roman intellectuals and sketches his complex standpoint towards the principate and Trajan.

Les médiations de l'immédiateté : l'individualisme communautaire des assemblées pentecôtistes

Lorsqu'il est amené à témoigner de sa conversion, le membre d'une assemblée pentecôtiste insiste avant tout sur la dimension personnelle de son choix de vie et sur les manifestations divines qui l'ont encouragées et qui l'encouragent encore chaque jour dans cette voie. Avoir fait l'expérience personnelle de l'agir divin est un élément constitutif de tout récit de conversion. Cet article, basée sur des recherches doctorales menées auprès de deux assemblées pentecôtistes de l'Est de la France, cherche à mettre en évidence que cette relation personnelle et intime entre le fidèle et son créateur se construit dans le cadre communautaire : à travers l'harmonisation des récits de conversion et la structuration des réunions de prières assurant par les manifestations charismatiques la mise en présence de l'Esprit Saint au sein de la communauté des fidèles. C'est en effet sur une validation communautaire que reposent en partie les convictions individuelles. When he has to testify of his conversion, the member of a Pentecostal assembly insists above all on the personal dimension of his choice of life and on the divine intervention which has encouraged him and which will encourage him in his everyday life in this way. The personal experience of God's action is a constituent element of any narrative of conversion. This article, based on my PhD researches carried on with two Pentecostal assemblies located in the east of France, tries to highlight that this personal and intimate relation between the believer and his creator is built in the community framework : harmonization of the narratives of conversion, structuralization of the meetings of prayers and charismatic interventions of the Holy Spirit within the community of the believers. Individual convictions are partly based and validated by the community.

Réflexions sur les céramiques fines en Gaule interne de La Tène finale au début du Haut-Empire : comparaisons d'ensembles et essai de caractérisation des phénomènes d'acculturation

Le concept de romanisation ne revêt d'utilité que s'il peut être qualifié, et donc analysé en différents « niveaux », afin de comparer les rythmes et les formes du phénomène dans les régions de l'Empire. Avant même de chercher à tenir un discours global sur la romanisation, il faut donc en étudier les multiples aspects de manière spécifique. C'est dans ce cadre que s'inscrit cette thèse de doctorat dont le but est de quantifier et de qualifier l'acculturation des céramiques fines en Gaule interne (200 BC - 50 AD). Fondée sur un corpus de quelques 130 ensembles, provenant de 21 sites urbains localisés entre le centre ouest de la France, l'Auvergne, le Plateau suisse et le Luxembourg, cette étude se caractérise par la mise en place de nouvelles approches méthodologiques, s'appuyant sur le calcul d'un « indice de romanisation » (quantifiant la romanisation d'un ensemble sur une échelle de 1 à 100) et sur l'analyse des modalités du phénomène. L'examen diachronique et cartographique des résultats obtenus montrant de fortes disparités dans les processus d'acculturation des céramiques fines, des niveaux de romanisation ont pu être définis, dont le principal intérêt est d'ouvrir la comparaison avec les autres aspects de l'acculturation des Gaules (instrumentum culinaire, technique de construction, romanisation de l'anthroponymie...). The concept of Romanisation can only be considered useful if it can be qualified and analysed at different levels in order to compare the acculturation rates, frequency and form of the phenomenon among the regions in the Empire. But before an overview of Romanisation can be considered, its multiple aspects must be examined in a specific manner. Among the French speaking areas, it is only recently that research concerning Gaulish and Roman periods has risked expanding the scope to a supra regional scale. Against this background, the purpose of my doctoral thesis is to examine the qualitative and quantitative aspects of acculturation among Gaulish fine wares (200 BCE - 50 CE). Based on a corpus of 130 assemblages from 21 urban sites from the western centre of France, Auvergne, the Swiss plateau and Luxembourg, the study is characterised by new methodological techniques relying on the calculation of a 'Romanisation index' (quantifying the level of Romanisation of an assemblage on a scale of 1 to 100) and the analysis of the methods of the phenomenon. The diachronic and cartographic examination of the results obtained showed large disparities in the acculturation processes concerning fine wares. The level of Romanisation could be defined, thus allowing a comparison with other aspects of the acculturation process among other aspects of Gaulish culture such as tools, cuisine, construction techniques and Romanisation of anthroponyms.
