Résumé : International audience
Aims: The aims of this study were to compare short-and long-term outcomes for clinical T2N0 oesophageal cancer with analysis of (i) primary surgery (S) versus neoadjuvant therapy plus surgery (NS), (ii) squamous cell carcinoma and adenocarcinoma subsets; and (iii) neoadjuvant chemoradiotherapy versus neoadjuvant chemotherapy.Methods: Data were collected from 30 European centres from 2000 to 2010. Among 2944 included patients, 355 patients (12.1%) had cT2N0 disease; 285 (S) and 70 (NS), were compared in terms of short-and long-term outcomes. Propensity score matching analyses were used to compensate for differences in baseline characteristics.Results: No significant differences between the groups were shown in terms of in hospital morbidity and mortality. Nodal disease was observed in 50% of S-group at the time of surgery, with 20% pN2/N3. Utilisation of neoadjuvant therapy was associated with significant tumour downstaging as reflected by increases in pT0, pN0 and pTNM stage 0 disease, this effect was further enhanced with neoadjuvant chemoradiotherapy. After adjustment on propensity score and confounding factors, for all patients and subset analysis of squamous cell and adenocarcinoma, neoadjuvant therapy had no significant effect upon survival or recurrence (overall, loco-regional, distant or mixed) compared to surgery alone. There were no significant differences between neoadjuvant chemotherapy and chemoradiotherapy in short-or long-term outcomes.Conclusion: The results of this study suggest that a surgery alone treatment approach should be recommended as the primary treatment approach for cT2N0 oesophageal cancer despite 50% of patients having nodal disease at the time of surgery.

Résumé : National audience
Pneumocystis jirovecii (P. jirovecii) est un champignon atypique et transmissible à fort tropisme pulmonaire. La prévalence de P. jirovecii chez les patients atteints de mucoviscidose a été évaluée en Allemagne à 7,4 %, en Espagne à 21,6 % et au Brésil à 38,2 %. En revanche, les données concernant la prévalence de P. jirovecii chez les patients atteints de mucoviscidose en France restent parcellaires en particulier en Bretagne, région où la prévalence de la mucoviscidose est élevée. L’objectif de ce travail a été de déterminer la prévalence de la colonisation de P. jirovecii en Bretagne chez les patients mucoviscidosiques suivis dans les CRCM de Rennes et de Brest-Roscoff. Les expectorations de 86 patients (178 prélèvements) suivis à Rennes et 76 patients (146 prélèvements) suivis à Brest-Roscoff ont été analysées rétrospectivement. La détection de P. jirovecii a été réalisée à l’aide d’une PCR en temps réel ciblant le gène codant pour l’ARN de la grande sous-unité du ribosome de la mitochondrie. P. jirovecii a été détecté chez 3/86 patients (3,5 %) suivis à Rennes et 1/76 patients (1,3 %) suivis à Brest-Roscoff, soit une prévalence globale de 2,5 %. Ces résultats portant sur 2 centres bretons montrent que la prévalence de P. jirovecii chez les patients atteints de mucoviscidose en Bretagne est faible en comparaison de celle observée en Allemagne, en Espagne et au Brésil. Cette étude constitue l’étape préalable indispensable pour déterminer les facteurs de risque d’acquisition du champignon chez les patients mucoviscidosiques et expliquer ces différences de prévalence

Résumé : International audience
Plastids are supported by a wide range of proteins encoded within the nucleus and imported from the cytoplasm. These plastid-targeted proteins may originate from the endosymbiont, the host, or other sources entirely. Here, we identify and characterise 770 plastid-targeted proteins that are conserved across the ochrophytes, a major group of algae including diatoms, pelagophytes and kelps, that possess plastids derived from red algae. We show that the ancestral ochrophyte plastid proteome was an evolutionary chimera, with 25% of its phylogenetically tractable proteins deriving from green algae. We additionally show that functional mixing of host and plastid proteomes, such as through dual targeting, is an ancestral feature of plastid evolution. Finally, we detect a clear phylogenetic signal from one ochrophyte subgroup, the lineage containing pelagophytes and dictyochophytes, in plastid-targeted proteins from another major algal lineage, the haptophytes. This may represent a possible serial endosymbiosis event deep in eukaryotic evolutionary history.

Résumé : Martinique is a French overseas department whose economy relies heavily on agriculture. Organochlorine pesticides, mainly chlordecone, were used for banana cultivation to eradicate banana weevil over a period of 40 years. Chlordecone is chemically stable,and has a strong affinity for fatty tissues. It is therefore able to bioaccumulate in animals and thereby represent a threat to ecosystems and man. Soils from banana plantations in Martinique are heavily contaminated with chlordecone. Possible transfer of these molecules from agricultural watersheds to the aquatic environment and the organisms that live in it is feared. The hypothesis that ecosystems of Martinique might be highly contaminated with this organochlorine pesticide was investigated. Chlordecone levels were measured in various freshwater and marine species. Data show a heavy contamination of many carnivorous and detritivorous species (fish and prawns). Concentrations measured in wild or farmed tilapia are among the highest ever reported in the literature. Some coastal species (fish and lobster) were also found to be contaminated, although to a lesser extent. Given the biogeochemical behavior of chlordecone, the most likely route of contamination is food. Detected concentrations in marine organisms are below the tolerated limits established by authorities. however. the impact of other sources of exposure, namely, contaminated water and root vegetables, remains to be investigated.

Résumé : International audience
OBJECTIVE: We hypothesized that, in Human Immunodeficiency Virus and Hepatitis C Virus (HIV/HCV) co-infected patients who did not respond to peg-interferon and ribavirin, a maintenance therapy with peg-interferon could induce fibrosis regression. METHODS: This was a randomized study with two parallel groups. HIV/HCV co-infected patients received peg-interferon α-2a at 180 μg/week or remained on observation for 96 weeks. The primary endpoint was the percentage of patients who experienced a decrease of at least one point in their Metavir fibrosis score between initial and final liver biopsies. Secondary endpoints included plasma fibrosis markers at week 96, occurrence of HCV-related complications, and survival. RESULTS: A total of 52 patients were randomized (peg-interferon: 25; control: 27) including 18 with cirrhosis. The median (interquartile range) age was 44 (40-46) years, and 69% were male. A total of 64% had ALT levels >1.5 normal values, and the CD4 cell count was 391 (296-537) cells/mm(3); 67% of patients had HIV RNA <200 copies/mL at entry. The main endpoint was assessed in 41 patients. Response rates were 3/20 (15%) and 4/21 (19%) in the peg-interferon and control groups, respectively (p = 0.99). There was no significant difference between peg-interferon and control groups on plasma fibrosis markers at the final visit. Severe liver-related complications were observed in 2 and 5 patients in peg-interferon and control groups, respectively. Three deaths were observed, all in the control group. CONCLUSIONS: A maintenance therapy with peg-interferon α-2a over 96 weeks in HIV/HCV co-infected patients, who were non-responders to HCV treatment, did not change liver fibrosis.

Résumé : International audience
Die antike Siedlung von Mandeure und Mathay (Epomanduodurum), welche durch ihre Größe und ihre monumentale Ausstattung als die zweitwichtigste Stadt der Sequaner hinter der Civitashauptstadt Besançon betrachtet wird, ist Gegenstand eines interdisziplinarischen Forschungsprogramms. Dieser Artikel stellt eine Bilanz der Ergebnisse der zwischen 2001 und 2004 durchgeführten Forschungen dar. Im Mittelpunkt der Forschungen der ersten Phase stand der zentralen Teil der Siedlung mit dem Bereich Heiligtum-Theater-spätrömische Befestigung, der für die Problematik der Entstehung, der Entwicklung und dem Ende der römischen Besiedlung besonders interessant ist. Verschiedene, sich ergänzende Projekte wurden eingeleitet: Erforschung des alten Dokumentarbestandes, geophysikalische Prospektionen, geoarchäologische Sondierungen, Plangrabungen, architektonische Untersuchunge. Durch diese Projekte war es möglich, die Kenntnisse über die drei wichtigen Großbauten (Heiligtum-Theater-spätrömische Befestigung) grundsätzlich zu vertiefen und insbesondere die geophysikalischen Prospektionsergebnisse lassen in bemerkenswerter Weise einen dichten Baubestand dieses Stadtteils erkennen. Schließlich konnte die Funktion und die Entwicklung der Flußebene des Doubs in diesem Bereich besser verstanden werden als auch die Art und Weise in welcher die antike Monumentalanlage in diesen einzigartigen natürlichen Rahmen einbezogen wurde.
Since 2001, a collective pluridisciplinary research programme is being undertaken on the antique town of Epomanduodurum in the communes of Mandeure and Mathay. This site is considered like the second one of the Sequani, for its dimensions and the monuments, after the civitas capital, Besançon. This article is an assessment of the investigations conducted between 2001 and 2004. During this period, the central part of the site was studied (sanctuary, theatre, Late fortification area), considered as the most significant for the question of the birth, development and decline of the town. Various complementary approaches have been carried out: study of archives, geophysical and geoarchaeological survey, extent excavations, architectural analyses. They lead to a better understanding of the three main buildings (the Celtic and Gallo-Roman sanctuary, the theatre of the Principate, the Late Antique fortification) and they add considerable informations about the pattern of settlement of this area; so it is possible to detect more precisely the spatial organization and finally to understand how the alluvial plain of the Doubs river was functioning and how the monumental complex has been integrated in such a peculiar landscape.
L'agglomération antique d'Epomanduodurum, située sur les communes de Mandeure et Mathay, et considérée comme la seconde du pays séquane par la taille et la parure monumentale, derrière la capitale de cité, Besançon, fait l'objet d'un programme collectif de recherche, pluridisciplinaire, depuis 2001. Cet article dresse un bilan des résultats des fouilles réalisées entre 2001 et 2004. Dans cette première phase, les investigations ont porté principalement sur la partie centrale du site (secteur sanctuaire-théâtrefortification tardive), perçue comme particulièrement intéressante pour la problématique de la naissance, du développement et du déclin de l'agglomération. Différentes approches complémentaires ont été lancées : étude du fond documentaire ancien, prospections géophysiques, sondages géoarchéologiques, fouilles extensives, études architecturales. Elles ont permis d'approfondir la connaissance des trois principaux édifices (sanctuaire laténien et gallo-romain, théâtre du Haut-Empire, fortification du Bas-Empire), de compléter de façon très notable la trame de l'occupation de ce secteur, et donc d'en mieux percevoir l'organisation spatiale, enfin de mieux comprendre le fonctionnement de la plaine alluviale du Doubs et l'insertion dans ce contexte naturel particulier d'un complexe monumental antique.

Résumé : International audience
Heartwood/sapwood profile and the tradeoff between trunk and crown increment in a natural forest: the case study of a tropical tree (Dicorynia guianensis Amsh., Fabaceae) Key message Sapwood area and the radial growth rate of the trunk follow the same pattern at breast height, with an initial increase and subsequent constant value, resulting from the increasing growth allocation toward the crown rather than tree decline. Heartwood area and heartwood volume in the trunk increase more rapidly after this shift occurs. Abstract Sapwood (SW) and heartwood (HW) are two functionally distinct classifications of wood in perennial stems for which quantities can vary greatly in tropical trees. Numerous positive correlations have been found between the radial growth rate (RGR) and SW quantity; however, variations in the SW/HW quantities have not been studied in light of the ontogenetic variation of RGR. Wood core sampling, intensive measurements of tree structure (number of branches, stem volumes), and radial growth monitoring were performed on an abundant and highly exploited tree species in French Guiana (Dicorynia guianensis) to investigate the relationship between RGR, SW/HW quantity, tree structure, and their variations on the course of a tree's ontogeny. SW area and RGR followed the same pattern of variation throughout tree development, both increasing first and reaching a steady state after 50 cm DBH (diameter at breast height). After this value, we observed a strong increase in both the HW area and HW volume increment, concomitant with a more rapid increase in crown volume. The stabilization of RGR for trees with DBH >50 cm was related not to a tree's decline but rather to an increasing wood allocation to the crown, confirming that RGR at breast height is a poor indicator of whole-tree growth for bigger individuals. We also confirmed that HW formation is an ontogenetic process managing SW quantity that is continuously and increasingly produced within the crown as the tree grows. This study highlights the effect of growth-mediated ontogenetic changes on the localization of water and carbohydrate storage within a tree, resulting from SW and HW dynamics throughout tree ontogeny.

Résumé : International audience
The astronomical and geodetic observatory OCA, located on the karst plateau of Calern (Caussols, France), has been monitoring earth deformation for several years. Two long baseline tiltmeters have been installed in a shaft in 2007, along with classical hydrogeological monitoring tools in order to investigate the relationship between current karst deformation and hydrology. Dye tests have shown that the plateau is drained towards the East, to the spring of Bramafam, except for its Western third. Karst tilting, as recorded by the tiltmeters, is linked to rainfall events. These instruments bring additional information to characterize different reservoirs: the deep karst aquifer of Bramafan with high amplitude oscillations of its water table, up to 100 m, the perched aquifer of Moustiques shaft whose response is attenuated, and several slope aquifers with reduced oscillations (Fontaniers, Castel Bon Pré). Tilt deformation reaches 8 μrad with a definite orientation between N90°E and N100°E. The best correlation between hydrology and tilts is observed for the deep aquifers. If the first autumn rainfall is ineffective on tilt, it recharges the epikarst and refills the reserves. The winter rains cause the water to flush towards the eastern deep aquifer and provokes a quick tilting of the plateau. Finally, the long term variations in tilt and water table show a very good correlation The relationship between current hydrological deformations and tectonics is also analyzed; broken and shifted speleothems in the shafts indicate a general shift of the plateau towards the south.
