Résumé : International audience
The Convective and Orographically- induced Precipitation Study (COPS) is a coordinated international project, comprised of an observational field campaign and a research programme aiming to advance the quality of fore- casts of orographically-induced pre- cipitation by four-dimensional obser- vations and modelling of its life cycle. The COPS field campaign took place during June-July-August 2007 over eastern France and south-western Germany. Its main objective was to provide an unprecedented comprehen- sive set of in situ and remotely-sensed meteorological observations of the entire depth of the troposphere. After a short overview of the project, the paper focuses on the French contribution to the COPS field phase, describes the experimental setup and highlights some key observations.
L’étude des précipitations convectives induites par l’orographie (Cops selon l’acronyme anglais) est un projet inter- national coordonné qui comprend une campagne d’observations de terrain et un programme scientifique et qui vise à améliorer la qualité des prévisions des précipitations orographiques convectives à la fois par l’observation quadridimensionnelle et la modélisa- tion de leur cycle de vie. La campagne de terrain s’est déroulée en juin-juillet- août 2007 sur l’est de la France et le sud-ouest de l’Allemagne. Son objectif majeur était de fournir un jeu d’obser- vations météorologiques, in situ et à distance, aussi complet que possible et sur toute la profondeur de la colonne troposphérique.Après une brève revue d’ensemble du projet, l’article se concentre sur la contribution française à la campagne Cops, décrit le dispositif expérimental mis en œuvre et met en valeur quelques observations clés.

Résumé : International audience
Among infertile couples, approximately half have to face with male infertility. In men with non-obstructive azoospermia, surgical retrieval testicular sperm extraction (TESE) of spermatozoa can be attempted, but with low success rates. A specific biomarker that could predict residual spermatogenesis would obviously be of interest before performing TESE. Thus, our aim was to identify biomarkers of residual spermatogenesis in seminal plasma of patients with non-obstructive azoospermia (NOA) using an isotope-coded protein label (ICPL)-based proteomic strategy coupled with conventional protein assay. This retrospective study was conducted in 40 men with NOA at the University Hospital of Nantes and Proteomics Core facility Biogenouest - Inserm U1085 - IRSET, Rennes, France. Comparative ICPL proteomic screening of frozen seminal plasma and correlation with TESE outcome allowed the identification of some differentially expressed proteins. Among them, lectin galactoside-binding, soluble 3 binding protein (LGALS3BP) expression was further confirmed using conventional protein assay, and its interest as a predictor of TESE outcome was then evaluated and compared with conventional clinical and hormonal markers of residual spermatogenesis. Among the 12 differentially expressed proteins identified with comparative ICPL proteomic strategy, seminal LGALS3BP expression was found to be significantly higher in men with successful TESE. Finally, comparative ICPL proteomic screening of seminal plasma appears to be a promising approach for the identification of biomarkers of residual spermatogenesis. LGALS3BP, associated with clinical and hormonal markers, could potentially be used as a predictive marker of successful TESE outcome in patients with NOA.

Résumé : International audience
We present the 1998-2009 GPS-derived velocity field for the Armenia region based on a survey-mode observation network of 31 GPS sites.We combine our results with previous GPS studies of the region to better assess the deformation of the Lesser Caucasus and Kura basin region. The results show that the Kura basin and the Lesser Caucasus regions are two different blocks, and that the main fault (Pambak-Sevan-Sunik) between these two regions has a right-lateral slip rate of 2±1 mm/yr. This is consistentwithmorphotectonic estimates and suggests a fairly constant slip rate over the last 120-300 ka. The right-lateral slip rate on one of the southern branch of the Pambak-Sevan-Sunik fault is lower than 1 mm/yr and the good agreementwith a geologically estimated slip rate suggests a constant slip rate over the last 1.4 Myr. The Sardarapat and Akhurian faults experience some shortening. This shortening is consistentwith someindependent geological estimates and shows the Arabian push.However, NNW-SSE-orientated faults have an extensional fault normal component instead of the expected shortening due to the Arabia-Eurasia convergence. This substantial extensive strain, and the sharp azimuth change of the velocity vectors between the Arabia promontory and the Lesser Caucasus suggest that processes other than "extrusion", possibly related to old subduction or delamination, contribute to the geodynamics of the region.

Résumé : International audience
Introduction Adverse effect of environmental exposures on the pregnancy is now clearly stated in the literature. Chemical, biological, or physical agents are susceptible to influence the onset of the pregnancy, as well as the fetal development. This paper aims to summarize basic knowledge on the topic. Methods A literature review was conducted based on a targeted search on the Medline database. Results Literature data suggested increased risk of congenital malformation, fetal growth, or impaired neurodevelopment. Adverse environmental effects can be observed during the pregnancy, at birth, during the childhood, during the adulthood, and possibly on the next generation. Discussion Prevention tools can be used to limit several domestic, occupational or lifestyle exposures. While emphasizing the importance of the prevention, it is necessary to remind to pregnant women that frequency of adverse pregnancy outcomes remain uncommon, considering the systematic exposures to a large panel of reprotoxicants. © 2017 Elsevier Masson SAS

Résumé : International audience
The island of Taiwan is located on the convergent boundary between the Philippine Sea plate and the Chinese continental margin. It offers very active mountain building and collapsing processes well illustrated by the rugged topography, rapid uplift and denudation, young tectonic landforms, active faulting and numerous earthquakes. In this paper, using simple models, we have estimated vertical movements and associated absolute gravity variations which can be expected along a profile crossing the southern part of the island and probably suffering the highest rates of rising. The two different tectonic styles proposed for the island, thin-skinned and thick-skinned, were taken into account. Horizontal and vertical movements were modeled by an elastic deformation code. Gravity variations due to these deformations are then modeled at a second step. They are dominated by plate and free-air effects, i.e. elevation of the topography, with several mu Gal yr(-1). By comparison, gravity changes generated by mass transfers are weak: maximum 0.1 mu Gal yr(-1) with the thin-skinned tectonic and 0.3 mu Gal yr(-1) with the thick-skinned tectonic. Though elastic rheology has limitations, this modeling offers interesting results on what gravity signal can be expected from the AGTO project (Absolute Gravity in the Taiwanese Orogen), which proposes to study the dynamic of these mountain ranges using absolute gravimetry (AG) and also including relative gravimetry (RG) and GPS measurements.

Ehrlichia is a large genus of obligate intracellular Gram-negative bacteria transmitted by ticks that cause several emerging infectious diseases in humans and are pathogenic on rodents, ruminants, and dogs. Ehrlichia spp. invade and replicate either in endothelial cells, white blood cells, or within midgut cells and salivary glands of their vector ticks. In this review, we discuss the insights that functional studies are providing on how this group of bacteria exploits their host by subverting host innate immunity and hijacking cellular processes.

Résumé : International audience
The Mediterranean hydrometeorological observatory Cévennes-Vivarais (OHM-CV) coordinates hydrometeorological observations (radars, rain gauges, water level stations) on a regional scale in southeastern France. In the framework of OHM-CV, temporary GPS measurements have been carried out for 2 months in autumn 2002, when the heaviest rainfall are expected. These measurements increase the spatial density of the existing permanent GPS network, by adding three more receivers between the Mediterranean coast and the Cévennes-Vivarais range to monitor maritime source of water vapour flow feeding the precipitating systems over the Cévennes-Vivarais region. In addition, a local network of 18 receivers covered an area of 30 by 30 km within the field of view of the meteorological radar. These regional and local networks of permanent and temporary stations are used to monitor the precipitable water vapour (PWV) with high temporal resolution (15 min). Also, the dense local network provided data which have been inverted using tomographic techniques to obtain the 3-D field of tropospheric water vapour content. This study presents methodological tests for retrieving GPS tropospheric observations from dense networks, with the aim of assessing the uncertainties of GPS retrievals. Using optimal tropospheric GPS retrieval methods, high resolution measurements of PWV on a local scale (a few kilometres) are discussed for rain events. Finally, the results of 3-D fields of water vapour densities from GPS tomography are analysed with respect to precipitation fields derived from a meteorological radar, showing a good correlation between precipitation and water vapour depletion areas.

Résumé : National audience
Since the 1950s, Friedman's curves served as reference to guide obstetrical practice around the world. However, recent studies have suggested guidelines based on Freidman's results were too stringent and induce inappropriate and excessive interventionism. The committee aimed to redefine the structure and the normal duration of the labor, as well as the criterion to be fulfilled to consider a labor as abnormal. Several recommendations have been produced based on a systematic literature review. Labor dystocia should not be diagnosed during the latency phase. The beginning of the active phase of the 1st stage of labor has been established between 5 and 6 cm of cervical dilatation, which is later than previously suggested. Rate of cervical dilatation is considered as abnormal below 1 cm per 4 hour during the first part of the active phase, and blow 1 cm per 2 hour above 7 cm of dilatation. A maximum duration for the 2nd stage of labor cannot be defined in the French context, based on the literature. However, exceeding 3 hours, the risk-benefit balance becomes less beneficial. These new guidelines would help to reduce the use of oxytocin and caesarian delivery for labor dystocia. © 2016 Elsevier Masson SAS

Résumé : International audience
Impact of GPS (Global Positioning System) data assimilation is assessed here using a high-resolution numerical weather prediction system at 2.5 km horizontal resolution. The Zenithal Tropospheric Delay (ZTD) GPS data from mesoscale networks are assimilated with the 3DVAR AROME data assimilation scheme. Data from more than 280 stations over the model domain have been assimilated during 15-day long assimilation cycles prior each of the two studied events. The results of these assimilation cycles show that the assimilation of GPS ZTD with the AROME system performs well in producing analyses closer to the ZTD observations in average. Then the impacts of assimilating GPS data on the precipitation forecast have been evaluated. For the first case, only the AROME runs starting a few hours prior the triggering of the convective system are able to simulate the convective precipitation. The assimilation of GPS ZTD observations improves the simulation of the spatial extent of the precipitation, but slightly underestimates the heaviest precipitation in that case compared with the experiment without GPS. The accuracy of the precipitation forecast for the second case is much better. The analyses from the control assimilation cycle provide already a good description of the atmosphere state that cannot be further improved by the assimilation of GPS observations. Only for the latest day (22 November 2007), significant differences have been found between the two parallel cycles. In that case, the assimilation of GPS ZTD allows to improve the first 6 to 12 hours of the precipitation forecast.

Résumé : International audience
The two experiments reported in the present paper concern (i) the differential imagery value of French and Creole and (ii) the influence of language on the recall of sequences of patterned movements in a bilingual population. Creole words were obtained a higher imagery value than French words, certainly because Creole is an oral and vernacular language. Motor recall scores were better when the sequence was presented in Creole compared to French. The generation of visual images by Creole would facilitate the memorization and recall of new sequences of movements. The effect of language on imagery value of words and motor recall among bilingual French–Creole subjects was discussed in terms of nature of information encoding in each language.
Les deux expérimentations relatées dans cet article évaluent la valeur d'imagerie de mots et le rappel moteur d'enchaînements auprès de bilingues français–créole en faisant varier la langue de présentation. Les mots en créole, supposés susciter plus facilement des images mentales visuelles, car le créole est une langue orale et vernaculaire, ont effectivement obtenu une cote plus élevée que les mots français sur l'échelle de valeur d'imagerie. L'évocation d'images visuelles facilitant la mémo-risation et la planification de séquences de mouvements, les performances de rappel obtenues à partir des consignes en créole ont été supérieures à celles obtenues en français. Les effets de la langue de présentation sur la valeur d'imagerie des mots et le rappel moteur d'enchaînements de morphocinè-ses auprès des participants bilingues sont discutés en termes de nature d'encodage de l'information verbale dans chacune des langues.
