Risso’s dolphins, pilot whales and sperm whales rarely strand in the northwestern Mediterranean. Thus, their feeding ecology, through the analysis of stomach contents, is poorly known. The aim of this study was to gain further insight into the segregation/superposition of the diet and habitat of Risso’s dolphins, pilot whales and sperm whales using chemical tracers, namely, stable isotopes (d13C, d15N) and orga- nochlorines. Significantly different d15N values were obtained in Risso’s dolphins (11.7 ± 0.7‰), sperm whales (10.8 ± 0.3‰) and pilot whales (9.8 ± 0.3‰), revealing different trophic levels. These differences are presumably due to various proportions of Histioteuthidae cephalopods in each toothed whale’s diet. Similar d13C contents between species indicated long-term habitat superposition or corroborated impor- tant seasonal migrations. Lower congener 180 concentrations (8.20 vs. 21.73 lg.g􏰀1 lw) and higher tDDT/ tPCB ratios (0.93 vs. 0.42) were observed in sperm whales compared with Risso’s dolphins and may indi- cate wider migrations for the former. Therefore, competition between these species seems to depend on different trophic levels and migration patterns. [less ▲]

À la Renaissance, le trésor ne disparaît pas au profit de la collection, telle qu’elle se (re)déploie à partir de la seconde moitié du XIVe siècle. En témoigne le trésor que les rois de France ont détenu au XVIe siècle. Sous le règne de François Ier, les pièces précieuses et coûteuses sont conservées dans le château de Blois, puis dans la chambre du trésor des bagues de Fontainebleau. Sous Charles IX, quand sévissent les guerres de religion, le trésor est mis à l’abri dans la forteresse de la Bastille. Il n’en n’est pas pour autant progressivement démembré : donnés ou envoyés à la fonte, de nombreux objets quittent alors le domaine royal. Quand Henri IV monte sur le trône de France, le trésor des rois Valois a pratiquement disparu. Pour le reconstituer, le premier Bourbon puise dans le trésor des rois de Navarre, qui devient ainsi le trésor des rois de France. Comme auparavant, tout en donnant à voir le faste de la cour et sa puissance, le trésor constitue donc une réserve de matières précieuses que l’on peut, au besoin, monnayer, offrir, fondre ou mettre en gage. Progressivement toutefois, il convient de démontrer aussi son savoir culturel. Dès lors, d’autres objets forcent l’admiration. Il s’agit de petites antiquités, de naturalia, d’objets exotiques, mais aussi de tableaux et de sculptures, c’est-à-dire des pièces dont la valeur est désormais plutôt déterminée par l’esthétique ou par l’origine lointaine et mystérieuse que par la préciosité du matériau utilisé pour sa confection.

Depuis la parution en 1966 de L’analyse structurale du récit, l’usage que fait le discours d’information du récit a donné lieu à un très grand nombre de travaux. Emportée par ce succès, la notion de récit y subit par ailleurs un fléchissement conceptuel qui peut aller jusqu’à désigner la « super forme » implicite à laquelle les médias de masse renverraient nécessairement lorsqu’ils relaient événements ou informations. Un important ensemble de recherches ( inspirées des théories littéraires, notamment la narratologie, des recherches sur le récit « postmoderne » ou, plus récemment, du travail de Paul Ricoeur ou Michel de Certeau sur les liens entre récit et vie quotidienne), ont fait évoluer la manière dont la catégorie « récit » est susceptible de questionner le discours d’information. Cet article propose une lecture épistémologique de cette évolution, et rend compte des conditions d’émergence des enjeux actuellement questionnés dans l’étude des récits d’information. Il montre comment se sont imposées les questions liant récit, mythe et histoire collective puis, plus récemment, récit et fiction, et expose les raisons pour lesquelles, aujourd’hui, ces questions sont déportées vers une approche plus pragmatique, centrée sur la narration en tant qu’elle est un processus de médiation. L’ensemble de ces réflexions impose de clarifier une situation notionnelle parfois confuse ; l’article propose ainsi de réarticuler ensemble récit et narration en leur adjoignant la notion de récitation.

Consciousness has been related to the amount of integrated information that the brain is able to generate. In this paper, we tested the hypothesis that the loss of consciousness caused by propofol anesthesia is associated with a significant reduction in the capacity of the brain to integrate information. To assess the functional structure of the whole brain, functional integration and partial correlations were computed from fMRI data acquired from 18 healthy volunteers during resting wakefulness and propofol-induced deep sedation. Total integration was significantly reduced from wakefulness to deep sedation in the whole brain as well as within and between its constituent networks (or systems). Integration was systematically reduced within each system (i.e., brain or networks), as well as between networks. However, the ventral attentional network maintained interactions with most other networks during deep sedation. Partial correlations further suggested that functional connectivity was particularly affected between parietal areas and frontal or temporal regions during deep sedation. Our findings suggest that the breakdown in brain integration is the neural correlate of the loss of consciousness induced by propofol. They stress the important role played by parietal and frontal areas in the generation of consciousness. [less ▲]

The dynamics of microbial stress response in intensive cultivation conditions remains not completely understood. In this work, two green fluorescent protein (GFP) transcriptional reporters have been used as biosensors of the heterogeneities generated in a two-compartment scale-down reactor. The stress promoters have been chosen for their responsiveness to carbon limitation corresponding to the global substrate profiles encountered in intensive fed-batch cultures. From our results, it can be concluded that the exposure of microbial cells to substrates heterogeneities tends to decrease the GFP expression level in fed-batch mode. Fluorescence intensities have been monitored at the single cell level by using flow cytometry. During the course of the fed-batch culture, a drop at the level of the intracellular GFP content has been observed for the two scale-down operating conditions and for the two promoters sensitive to substrate limitation (rpoS and csiE). The fluorescence drop can be attributed to the repression of these promoters but also to the release of GFP to the extracellular medium according to the increase of the fluorescence level of the supernatant. This leakage has been observed for all the operating conditions, i.e. the scale-down reactors and the culture operating in the normal mode, i.e. in a well-mixed bioreactor. Interestingly, GFP leakage is more pronounced in the case of the cultures operated in the normal mode. Indeed, staining by propidium iodide tends to be more elevated for the microbial cells cultured under the normal mode by comparison with those cultured in scale-down conditions, indicating a higher permeability of the membrane. These results suggest that GFP microbial biosensors could be used to detect simultaneously mixing imperfections and their impact on the viability of microorganisms. [less ▲]

Le rôle joué par les femmes de pouvoir au Moyen Âge et au tout début de la Renaissance dans la commande d’œuvres artistiques et culturelles constitue un champ de recherche de plus en plus prolifique. La présente collection d’articles, suscitée par une journée d’études intitulée "Le mécénat féminin en France et en Bourgogne (XVe-XVIe siècles). Nouvelles perspectives", qui a eu lieu à l’Université de Liège en 2010, illustre l’importance des femmes mécènes, en France et en Bourgogne, dans les domaines de l’architecture, de l’orfèvrerie, des manuscrits enluminés, de la peinture et de la sculpture, ainsi que dans la traduction et dans l’organisation des cérémonials. Dans leurs fonctions respectives, celles de reine, reine mère, duchesse, régente, dame d’honneur, les femmes font usage des œuvres d’art et des rites pour promouvoir leurs intérêts personnels et dynastiques, confrontées qu’elles sont aux difficultés liées à leur sexe et à leur statut de femme de pouvoir, ou à des difficultés telles que les rivalités, la guerre, ou la folie. Même s’il est clair que les cours française et bourguignonne constituent l’espace le plus favorable à l’efflorescence du mécénat féminin, cette collection démontre toutefois l’existence d’un même phénomène, important, en dehors des sphères royales.

The goal of RIC allo-SCT is to harness the graft-versus-leukemia (GVL) effect, while minimizing toxicities and the risk of GVHD. However, prior studies have shown a lower risk of relapse in AML patients (pts) who experienced chronic GVHD after RIC allo-SCT versus in those who did not. Here, we investigated the impact of occurrence of GVHD on transplantation outcomes in a large cohort of AML pts given allogeneic PBSC after RIC conditioning. Data from 1859 AML pts in first (n=1439) or second (n=420) CR transplanted between 2000 and 2009 following a RIC regimen at EBMT affiliated centres were analyzed. Pts were given PBSC from HLA-identical sibling (MRD, n=1208), or from HLA-matched unrelated donors (MUD, n=651). Median pt age at transplantation was 56 y (range, 18–77). 338 male pts were given grafts from female donors. RIC was based on low-dose TBI in 520 (28%) pts, while the remaining pts received chemotherapy-based RIC. ATG was given in 269 (22%) MRD and in 267 (41%) MUD recipients, respectively, while 151 (13%) MRD and 165 (25%) MUD recipients received in-vivo T cell depletion with alemtuzumab. The impact of chronic GVHD on relapse risk, non-relapse mortality (NRM), leukemia-free survival (LFS), and overall survival (OS) was assessed using time-dependent multivariate Cox models and in a landmark analysis at 18 months after transplant. Three-year incidences of relapse, NRM, LFS and OS were 34±1%, 15±1%, 51±2% and 60±2% in MRD recipients, respectively, and 34±2% (p=NS), 24±2% (P<0.001), 42±2% (P=0.001) and 47±2% (P=0.001) in MUD recipients, respectively. Grade II, III and IV acute GVHD were observed in 133 (11%), 61 (5%) and 30 (2%) MRD recipients and in 119 (18%), 41 (6%) and 24 (4%) MUD recipients, respectively. The 3-y cumulative incidence of chronic GVHD was 47%. Fifty-three percent of patients with chronic GVHD had extensive chronic GVHD, while the remaining 47% had limited chronic GVHD. In multivariate analyses, occurrence of grade II-IV acute GVHD was associated with a lower risk of relapse (HR=0.8; P=0.04), a higher risk of chronic (HR=2.2; P<0.001) and extensive chronic GVHD (HR=2.8; P<0.001), a higher risk of NRM (HR=2.4 P<0.001), a worsened LFS (HR=1.3; P=0.01), and a worsened OS (HR=1.5; P<0.001). In multivariate time-dependent analyses, occurrence of limited chronic GVHD was associated with a lower risk of relapse (HR=0.7; P=0.05), comparable NRM (HR=1.4; P=0.16), comparable LFS (HR=0.9; P=0.29) and better OS (HR=0.5; P<0.001), while occurrence of extensive chronic GVHD was associated with a lower risk of relapse (HR=0.6; P=0.01), higher NRM (HR=3.2; P<0.001), a trend for worsened LFS (HR=1.3; P=0.06) and comparable OS (HR=0.9; P=0.34). The median interval from transplantation to occurrence of chronic GVHD was 163 (range, 100–1545) days. To further assess the graft-versus-leukemia effect of chronic GVHD, we performed a landmark analysis in patients who were leukemia-free at 18 months after transplantation (n=776). Median follow-up from this landmark time-point was 24 (range, 0.1–112) months. Two-year relapse, NRM, LFS and OS were 16±2%, 2.5±1%, 82±2%, and 89±2%, respectively, in patients without chronic GVHD before the landmark time-point, versus 9±1% (P=0.001), 8±1% (P<0.001), 83±2% (P=0.65), and 86±2% (P=0.38), respectively, in patients with chronic GVHD before the landmark time-point.In conclusion, in this cohort of AML patients transplanted in remission, occurrence of chronic GVHD was associated with a lower risk of relapse that translated to better OS in patients with limited chronic GVHD but not in those with extensive chronic GVHD who experienced higher long term NRM, highlighting the need for long term prospective assessment of long term effects and quality of life in patients receiving RIC allo-SCT.

The fist lynx were seen in eastern Belgium at the end of the 1990s. Since then, both sightings and tracks have been recorded there and in the Ardenne (south east Belgium). Whether this presence indicates a spontaneous return of individuals deriving from the population reintroduced in Germany or results from illicit releases, it raises the question of the suitability and the carrying capacity of habitats in an area of dense human occupation. Using two software programs, a mapping model to assess habitat characterization, drawn from relevant criteria for this species, was tested to estimate the potential host of the study area, via the determination of areas of suitable habitats, and the dispersion potential of the species, through the identification of the most viable dispersal corridors. The findings of the study (multi criteria analysis of potential host of habitats, identification of corridors of lowest cost, estimation of the potential population...), compiled on the basis mapping model and simulations, suggest that a return of the lynx in Wallonia may be sustainable if supported and managed wisly by the regional administrative services.

Vietnam locates in the Asia-the most active region, where gains the highest economic growth rate and highest milk consumption in the world. Vietnam also ranks the second among the highest milk productivity in the Asia and milk consumption is increasing rapidly. However, the dairy industry in Vietnam is currently able to meet only 22% of domestic demand; the remaining amount has been imported (VOV/VNA, 2008). In addition, raw milk price is very low while retail price is too high. It leads to low effective in the production of the whole chain. This paper is based on the value chain approach within both quantitative and qualitative methods to evaluate a typical fresh value chain in the North of Vietnam in (Moc Chau platation) in 2008 - 2010. The findings show that the dairy plant is the most powerful actor in the chain and it drives the whole chain while power of dairymen is very weak. The value added of the chain is distributed unequally among its actors in whom more benefitable for non-dairy cow producers. In particular, the value added in dairy cow stage would be much lower.

This study investigates the turnover of polysaccharides by heterotrophic bacterioplankton in the northern Bay of Biscay, a productive marine system on the shelf-break of the temperate Atlantic Ocean. Field studies were conducted along the shelf-break south of Ireland and west of France (47° 07' 83'' N, 6° 92' 01'' E and 51° 34' 42'' N, 10° 49' 95'' E) during the development of phytoplankton blooms in late spring. Bacterial biomass production (BBP) near the surface ranged from 0.5 to 27.4 nmol C L-1 h-1 in both years. A direct relationship between BBP and the concentration of total polysaccharides strongly suggests the dependence of bacterial growth on the availability of semi-labile organic matter. Concentrations of combined glucose as well as rate constants of extracellular glucosidase activity and glucose uptake were determined to estimate the actual carbon fluxes from bacterial polysaccharide turnover. Results reveal that the degradation of polysaccharides n the upper 100 m of the water column sustained on average a glucose flux of 2.6 mmol C m-2 d-1 i that was available for bacterial uptake. The mean turnover time for polysaccharides was 170 and 165 days for alpha- and beta-glycosidic linked polymers, respectively. Free glucose, the labile hydrolysate of polysaccharides, had a mean turnover time of 4.5 days and supported 2.2 to 18.4% of BBP. The incorporation of glucose into bacterial biomass was stimulated by the availability of inorganic nitrogen. Overall, our results demonstrate that the bacterial recycling of polysaccharides in the Bay of Biscay generates a relevant flux of organic carbon in microbial food-webs and biogeochemical processes.
