Résumé : We studied the effects of a lactic acid bacterium, Pediococcus acidilactici (strain MA 18/5M, CNCM), as a dietary probiotic on growth performance and some nutritional and microbiological aspects of the shrimp Litopenaeus stylirostris. Experimental shrimp culture was carried out over 10 weeks, using floating cages of 14 m(2) each set in earthen ponds, in a New Caledonia farm affected by "Summer syndrome", a septicaemic vibriosis caused by Vibrio nigripulchritudo. The experiment design testing probiotic-coated pellets against control was replicated in two earthen ponds. High mortalities, characteristic of Summer syndrome, were observed during the first 2 weeks of the trial. The probiotic improved production in the treated cages from both ponds with increases in the survival rate (7% and 15% respectively) and final biomass (8% and 12% respectively). No differences were recorded among treatments on growth performances, but significant lower food conversion ratios were obtained with probiotic treatment. After 5 weeks of rearing, the Hepatosomatic Index and the adjusted dry weight of the digestive gland were significantly increased by 10% and by 9% respectively in shrimps treated with probiotic. In the meantime, the specific activities of alpha amylase and trypsin in the digestive gland showed a significant effect of the probiotic treatment with respective increases by 35% and 55%. The rise in total trypsin activity following morning feeding was also enhanced by the probiotic treatment (P < 0.001). The highest concentration of probiotic (between 10(4)-10(5) CFU g(-1) of fresh gut) in the shrimp gut was obtained 2 h after feeding. The concentration remained high for 4 h after feeding before decreasing until the next meal. Total bacterial counts on Marine agar and TCBS in the gut were significantly lowered by the probiotic treatment over the 10 weeks of the experiment. Additionally, during the first 2 weeks, prevalence and load of V nigripulchritudo strains in haemolymph was lower in animals fed with the probiotic diet. This study demonstrated, under pond conditions, that feeding shrimp with live terrestrial lactic acid bacteria can be an effective treatment for improving shrimp culture affected by vibriosis.

Résumé : The study, which is based on repetitive bathymetric surveys, assesses changes and effects of one of the most important floods recorded in the Rhone Delta area: bottom morphology and sediment distribution in the Rhone outlet after the December 2003 flood are discussed by comparison between Digital Terrain maps (DTMs) of November 2003 and January 2004. The post-flood morphology shows that the whole of the system is active, mainly in the east. The channel of the Rhbne has been hollowed out on the left bank by more than 5 m, the eastern coast of the mouth has retreated 400 m, the mouth-bar has prograded 200 m and the slope of the delta front has increased by 0.19. The overlay of pre- and post-flood DTMs makes it possible to estimate the total volume deposited in the [0 to -20 m] zone as +7.8 X 10(6) m(3) (i.e. 0.88 m(3) m(-2)), which corresponds to 4 X 10(6) t of sediment. These values are compared with the average annual volume of 0.47 X 10(6) m(3) yr(-1) of sediment deposited in this zone between 1995 and 2003, as well as the average sediment load estimated at the Arles station (50 km upstream) for this flood event (3.1 x 10(6) t to 5.3 x 10(6) t). The acquisition of bathymetric measurements immediately before and after a major flood allows more than a simple morphological description; in addition, an analysis of the solid load transfer processes towards the prodelta is achievable. Three mechanisms are highlighted. Most of the material eroded in the channel and supplied to the delta front corresponds to fine sediment that drape homogeneously over the pre-flood morphology of the delta front. The transit of the coarsest sediment (primarily sand) is slowed down in the channel of the Rh6ne: this sediment builds up in relatively small areas, leading to the formation of gullies on the prodelta slope. The gullies have fixed positions and disappear gradually towards the west, following the progressive migration of the active band towards the east. These old features are not reactivated by floods occurring after their formation. During the flood, only a small volume of coarse sediment bypasses through the gullies, and the fine deposits are remobilised rapidly or compacted. Flood input concerns essentially the delta front, which traps 90% of the fluvial solid discharge between 0 and 20 m depth. The coarse prodelta supply is then due mainly to mass movements of unconsolidated material deposited beforehand on the top of the delta front. Consequently, the main nourishment of the prodelta does not occur directly during and/or immediately after a flood event, but is delayed by sediment being temporarily trapped on the delta front.

Résumé : International audience
The present study is a contribution to the "neXt50 challenge", a coordinated effort across C-HPP teams to identify the SO most tractable missing proteins (MPs) on each chromosome. We report the targeted search of 38 theoretically detectable MPs from chromosomes 2 and 14 in Triton X-100 soluble and insoluble sperm fractions from a total of 15 healthy donors. A targeted mass spectrometry-based strategy consisting of the development of LC-PRM assays (with heavy labeled synthetic peptides) targeting 92 proteotypic peptides of the 38 selected MPs was used. Out of the 38 selected MPs, 12 were identified with two or more peptides and 3 with one peptide after extensive SDS-PAGE fractionation of the two samples and with overall low-intensity signals. The PRM data are available via ProteomeXchange in PASSEL (PASS01013). Further validation by immunohistochemistry on human testes sections and cytochemistry on sperm smears was performed for eight MPs with antibodies available from the Human Protein Atlas. Deep analysis of human sperm still allows the validation of MPs and therefore contributes to the C-HPP worldwide effort. We anticipate that our results will be of interest to the reproductive biology community because an in-depth analysis of these MPs may identify potential new candidates in the context of human idiopathic infertilities.

Résumé : International audience
ABSTRACT: Environmental exposures during pregnancy and early life may have adverse health effects. Single birth cohort studies often lack statistical power to tease out such effects reliably. To improve the use of existing data and to facilitate collaboration among these studies, an inventory of the environmental exposure and health data in these studies was made as part of the ENRIECO (Environmental Health Risks in European Birth Cohorts) project. The focus with regard to exposure was on outdoor air pollution, water contamination, allergens and biological organisms, metals, pesticides, smoking and second hand tobacco smoke (SHS), persistent organic pollutants (POPs), noise, radiation, and occupational exposures. The review lists methods and data on environmental exposures in 37 European birth cohort studies. Most data is currently available for smoking and SHS (N=37 cohorts), occupational exposures (N=33), outdoor air pollution, and allergens and microbial agents (N=27). Exposure modeling is increasingly used for long-term air pollution exposure assessment; biomonitoring is used for assessment of exposure to metals, POPs and other chemicals; and environmental monitoring for house dust mite exposure assessment. Collaborative analyses with data from several birth cohorts have already been performed successfully for outdoor air pollution, water contamination, allergens, biological contaminants, molds, POPs and SHS. Key success factors for collaborative analyses are common definitions of main exposure and health variables. Our review emphasizes that such common definitions need ideally be arrived at in the study design phase. However, careful comparison of methods used in existing studies also offers excellent opportunities for collaborative analyses. Investigators can use this review to evaluate the potential for future collaborative analyses with respect to data availability and methods used in the different cohorts and to identify potential partners for a specific research question.

Résumé : In most of marine fishes cultured, larvae in their early development are fed with live prey (rotifer and/or artemia). In hatcheries, culture of these preys is labour consuming, needs specific facilities and represent an important part of production cast. On the other hand, world artemia production is subjected to fluctuation of harvest in the wild which could Iimit fish farming industry in the near future. A dried formula adapted to marine fish larvae has been perfected by Ifremer's center of Brest (France) and is distributed by a feeding company since 1999. This artificial microbound diet has been successfully tested on several temperate fishes such as European seabass (Dicentrarchus labrax), Atlantic cod (Gadus morhua) or European seabream (Sparus aurata) in a co-feeding (i.e. artemia and dried diet) strategy. Experiments described here were carried out ta evaluate the performances obtained during total substitution of artemia by this diet in Red drum (Sciaenops ocellatus) larval culture. ln 2004 and 2005, four experiments were conducted on feed technology aspects (experimental or industrial manufacturing), weaning strategy (direct or co-feeding) and feed distribution method (prototypes or classical self feeder) in comparison to the standardized method using live preys. At the end of larval phase (day 15) and at day 30, end of nursery phase (0.6 g), survival relative to control (RTC) was respectively 96.9% and 111.0% in the best treatment. Concerning growth, the weight RTC reached at day 15 and day 30 was respectively 82.8% and 72.4%. However, it is important to note that rearing protocols have to be adapted ta the use of these micro pellets in order toprevent degradation of culture quality. These results show that this new product can be applied on industrial scale in private hatcheries. But further research is needed ta evaluate replacement of rotifers by this dried formula in order to completely eliminate live prey in larval culture of Red drum.
Dans la plupart des poisons marins élevés, les larves sont nourries avec des proies vivantes (rotifères et/ou artémia) au début de leur développement. Dans les écloseries, la culture de ces proies est consommatrice de main d'oeuvre, nécessite des installations spécifiques et entre pour une part importante dans le coût de production. Par ailleurs, la production mondiale d'artémia est dépendante de la fluctuation des récoltes dans le milieu naturel, ce qui pourrait gêner la filière piscicole marine dans un futur proche. Une formulation alimentaire inerte adaptée aux larves de poisson marin a été mise au point par le centre Ifremer de Brest (France) et est commercialisée par un provendier depuis 1999. Ces microparticules artificielles ont été testée avec succès sur plusieurs poissons tempérés comme le bar européen (Dicentrarchus labrax), la morue atlantique (Gadus morha) ou la daurade européenne (Sparus aurata) dans un contexte de co-feeding (i.e. artémia et aliment inerte). Les expériences décrites ici ont été menées afin d'évaluer les performances obtenues lors de la substitution totale des artémia par cet aliment dans l'élevage larvaire de l'ombrine (Sciaenops ocellatus). En 2004 et 2005, quatre expériences ont été menées sur l'aspect technologie alimentaire (fabrication expérimentale ou industrielle), la stratégie de sevrage (direct ou co-feeding) et le mode de distribution de l'aliment (distributeur classique ou prototypes) en comparaison au standard sur proies vivantes. En fin de phase larvaire (jour 15) et au jour 30 après une phase de prégrossissement (0.6g), la survie par rapport au témoin (RTC) était respectivement de 96.9% et 111 .1% dans le meilleur traitement. Concernant la croissance, les poids obtenus aux jours 15 et 30 atteignaient respectivement 82.8% et 72.4%. Cependant il est important de relever que les protocoles d'élevage doivent être adaptés à l'utilisation de ces microparticules afin de prévenir une dégradation de la qualité d'élevage. Ces résultats montrent que ce nouveau produit peut être appliqué à l'échelle industrielle dans les écloseries privées. Cependant, les recherches doivent être poursuivies pour évaluer les possibilités de remplacement des rotifères par ces aliments inertes afin de s'affranchir complètement de l'utilisation de proies vivantes dans l'élevage larvaire de l'ombrine.

Résumé : Fish culture (seabass, turbot...) on the French metropolitan coast, and shrimp culture in the overseas territories (essentially New Caledonia and Tahiti) are subject to a regular development through land based farms. Three thematic of research on aquaculture ponds are carried out in CREMA-L’Houmeau, in collaboration with producers. The aim of the first one is to determine the optimal rearing conditions (stocking density, water renewal rate, input of oxygen, rate of feeding...) which allow to minimise the quantity of wastes for a similar final biomass. The second part aims to reduce the nutrient loading in the effluent, through open-air treatments: sedimentation ponds, foam fractionation, mass production of phytoplankton, and rearing of molluscs on the produced phytoplankton. The third part concerns research aiming to model the “ production - treatment - valorisation ” relationships.

Résumé : International audience
Background: The Ras/Raf/MEK/ERK signaling pathway is involved in essential cell processes and it is abnormally activated in similar to 30 % of cancers and cognitive disorders. Two ERK isoforms have been described, ERK1 and ERK2; ERK2 being regarded by many as essential due to the embryonic lethality of ERK2 knock-out mice, whereas mice lacking ERK1 are viable and fertile. The controversial question of why we have two ERKs and whether they have differential functions or display functional redundancy has not yet been resolved. Results: To investigate this question we used a novel approach based on comparing the evolution of ERK isoforms' sequences and protein expression across vertebrates. We gathered and cloned erk1 and erk2 coding sequences and we examined protein expression of isoforms in brain extracts in all major clades of vertebrate evolution. For the first time, we measured each isoforms' relative protein level in phylogenetically distant animals using anti-phospho antibodies targeting active ERKs. We demonstrate that squamates (lizards, snakes and geckos), despite having both genes, do not express ERK2 protein whereas other tetrapods either do not express ERK1 protein or have lost the erk1 gene. To demonstrate the unexpected squamates' lack of ERK2 expression, we targeted each ERK isoform in lizard primary fibroblasts by specific siRNA-mediated knockdown. We also found that undetectable expression of ERK2 in lizard is compensated by a greater strength of lizard's erk1 promoter. Finally, phylogenetic analysis revealed that ERK1 amino acids sequences evolve faster than ERK2' s likely due to genomic factors, including a large difference in gene size, rather than from functional differences since amino acids essential for function are kept invariant. Conclusions: ERK isoforms appeared by a single gene duplication at the onset of vertebrate evolution at least 400 Mya. Our results demonstrate that tetrapods can live by expressing either one or both ERK isoforms, supporting the notion that ERK1/2 act interchangeably. Substrate recognition sites and catalytic cleft are nearly invariant in all vertebrate ERKs further suggesting functional redundancy. We suggest that future ERK research should shift towards understanding the role and regulation of total ERK quantity, especially in light of newly described erk2 gene amplification identified in tumors.

Résumé : International audience
Brecciated and fractured peridotites with a carbonate matrix, referred to as ophicalcites, are common features of mantle rocks exhumed in passive margins and mid-oceanic ridges. Ophicalcites have been found in close association with massive peridotites, which form the numerous ultramafic bodies scattered along the North Pyrenean Zone (NPZ), on the northern flank of the Pyrenean belt. We present the first field, textural and stable isotopic characterization of these rocks. Our observations show that Pyrenean ophicalcites belong to three main types: (1) a wide variety of breccias composed of sorted or unsorted millimeter- to meter-sized clasts of fresh or oxidized ultramafic material, in a fine-grained calcitic matrix; (2) calcitic veins penetrating into fractured serpentine and fresh peridotite; and (3) pervasive substitution of serpentine minerals by calcite. Stable isotopic analyses (O, C) have been conducted on the carbonate matrix, veins and clasts of samples from 12 Pyrenean ultramafic bodies. We show that the Pyrenean ophicalcites are the product of three distinct genetic processes: (1) pervasive ophicalcite resulting from relatively deep and hot hydrothermal activity; (2) ophicalcites in veins resulting from tectonic fracturing and cooler hydrothermal activity; and (3) polymictic breccias resulting from sedimentary processes occurring after the exposure of subcontinental mantle as portions of the floor of basins which opened during the mid-Cretaceous. We highlight a major difference between the eastern and western Pyrenean ophicalcites belonging, respectively, to the sedimentary and to the hydrothermal types. Our data set points to a possible origin of the sedimentary ophicalcites in continental endorheic basins, but a post-depositional evolution by circulation of metamorphic fluids or an origin from relatively warm marine waters cannot be ruled out. Finally, we discuss the significance of such discrepancy in the characteristics of the NPZ ophicalcites in the frame of the variable exhumation history of the peridotites all along the Pyrenean realm.

Résumé : International audience
There are emerging concerns about potential effects on child health and development of early-life exposure to substances such as brominated flame retardants (BFRs), perfluorinated compounds (PFCs), phthalates and phenols (including bisphenol A (BPA)); pregnancy and birth cohort studies are ideally designed to study such concerns prospectively. As part of the ENRIECO project, we evaluated existing human biomonitoring data for these substances in European birth cohorts and develop recommendations for more harmonized methods that will enable combination and comparison of cohort data in the future. The ENRIECO inventory shows that 20 European birth cohorts have measured or are measuring BFRs (N=10), PFCs (N=11), phthalates (N=16) or phenols (N=8). Generally, samples were collected prenatally or at birth and measurements involved few subjects in each cohort (a few hundred maximum). Biological matrices, timing, and analytical methods of the measurements varied between cohorts. Few cohorts have measured at multiple time points or in children. In European cohorts, levels of BFRs were very low and at least 10-fold lower than in US; levels of PFCs and phthalates have decreased over the last decade since the phasing out of certain of these compounds; concentrations of phenols are comparable to those in the US. Although there is little published data in the cohorts now, many measurements are ongoing and we recommend that cohorts start working towards combined and comparison studies. Specific recommendations for use of existing data include the development of conversion models for the different media used for measurement of persistent chemicals, and inter-laboratory comparisons and calibrations. Recommendations for further data collection include more evaluation of exposure to these chemicals in children; repeated measurements of non-persistent chemicals; validation and harmonisation of questionnaires; and the development of mechanisms for fast European birth cohort response for the detection and prioritisation of new chemicals of concern.
