Une certaine idée romantique du style a contribué, depuis le début du XIXe siècle, à développer une conception singularisante du style, qui associe celui-ci à l'expression d'une originalité de l'individu écrivant. Que faire alors de cette conception de la singularité en sociologie de la littérature, discipline qui privilégie l’explication par le collectif et s’attache à situer chaque pratique dans le tout social ? Comment retrouver les traces de l’individu social dans la matière verbale ou la trace écrite qu’il produit ? L’expression et la saisie d’une subjectivité, censées être le propre du style, sont-elles objectivables ? Dans quelle mesure les styles peuvent-ils rencontrer les dynamiques collectives ? Cet article propose un état de la question et quelques pistes méthodologiques à la lumière des approches sociales du littéraire. [less ▲]

Using first-principles calculations, we analyze the structural properties of tungsten trioxide WO3. Our calculations rely on density functional theory and the use of the B1-WC hybrid functional, which provides very good agreement with experimental data. We show that the hypothetical high-symmetry cubic reference structure combines several ferroelectric and antiferrodistortive (antipolar cation motions, rotations, and tilts of oxygen octahedra) structural instabilities. Although the ferroelectric instability is the largest, the instability related to antipolar W motions combines with those associated to oxygen rotations and tilts to produce the biggest energy reduction, yielding a P21/c ground state. This nonpolar P21/c phase is only different from the experimentally reported P c ground state by the absence of a very tiny additional ferroelectric distortion. The calculations performed on a stoichiometric compound so suggest that the low-temperature phase of WO3 is not intrinsically ferroelectric and that the experimentally observed ferroelectric character might arise from extrinsic defects such as oxygen vacancies. Independently, we also identify never observed R3m and R3c ferroelectric metastable phases with large polarizations and low energies close to the P 21 /c ground state, which makes WO3 a potential antiferroelectric material. The relative stability of various phases is discussed in terms of the anharmonic couplings between different structural distortions, highlighting a very complex interplay. [less ▲]

The Wels originates from central and East-Europe. It was introduced in Europe as early as the Middle Ages and in France the species has been released many times since the 19th century. It invaded the Loire river basin at the end of the last century. It is the largest predatory freshwater fish in Europe. Considering its recent increase in numbers and of range and its feeding behaviour, the Orleans museum coordinated a study of the species in the Loire valley from 2011 to 2014 in order to better know the species ecology and especially its choice of prey and food intake. The stomach contents from a sample of 60 individuals of all sizes, captured using nets, were analysed. It feeds on a wide variety of species, more than 23 were found during this study, mainly fish. Anadromous Fish and Lamprey made up an important part of the food intake (66%). [less ▲]

The collection of early medieval window glass found in the abbey of Baume-les-Messieurs (Jura, France) is exceptional because it dates to the end of the eighth century, and due to the number of fragments as well as their state of conservation. Different colours and forms have been identified. These pieces are a rare opportunity to address the glass craft, its recipes and techniques for a phase of its history that has remained little known. Analyses in PIXE–PIGE prove that, in addition to fragments from two soda glass items, the pieces are made from wood-ash glass. Most of them probably came from the same production and the raw material is present in the region. At this early stage of wood-ash glass production, the glassmakers had mastered the glass as well as the colour processes. [less ▲]

Objectifs : Le contrôle de la pression artérielle (PA) chez le patient hémodialysé (HD) est un enjeu majeur en raison des résultats controversés sur les risques cardiovasculaires qui y sont associés. Cependant, la mesure de la PA dans cette population est difficile à appréhender au vu de sa grande variabilité. L’exactitude des mesures péridialytiques (enregistrées dans l’unité d’HD pendant la séance) est souvent remise en question. L’objectif de notre étude est d’établir la contribution et la concordance entre deux techniques de mesure ambulatoire pour détecter la PA non contrôlée chez ces patients HD. Il s’agit du monitoring ambulatoire interdialytique de 44h (MAPA) et de l’automesure au domicile (HBPM) pendant une durée variable de 3, 5 et 7 jours. Méthodologie : 43 patients hémodialysés chroniques (H=28, F = 15), avec une moyenne de 68,3±13 ans ont réalisé une MAPA de 44h (Spacelabs 90207), de la fin d’une séance d’HD au début de la suivante, immédiatement suivie par une automesure de 7 jours (Omron M6). Les mesures péridialytiques étaient la moyenne des PA pré-dialyse ou post-dialyse enregistrées sur 2 semaines (6 séances d’HD). L’hypertension était définie par une PA égale ou supérieure à 140/90 mmHg pour la PA pré-HD, 130/80 mmHg pour la PA post-HD, 130/80 mmHg pour la MAPA de 44 h et 135/85 mmHg pour l’HBPM. Résultats : Nous avons constaté de bonnes corrélations entre la MAPA et l’HBPM pour le diagnostic de l’hypertension chez le patient HD. Comparées aux PA péridialytiques, les 2 techniques ambulatoires ont permis d’identifier la même proportion d’hypertension masquée et d’hypertension de la blouse blanche (25%). La plus grande précision de diagnostic sur le status tensionnel est retrouvée pour les plus longues périodes d’enregistrement (44h pour la MAPA et 7 jours pour l’HBPM). Les plus courtes périodes étaient mieux tolérées par les patients mais moins précises pour détecter l’hypertension. L’automesure était plus appréciée que la MAPA de 44h. Conclusion : La MAPA et l’automesure ont permis d’identifier un quart de patients avec un phénotype particulier d’hypertension, qui n’aurait pas été classé correctement en se fiant uniquement aux mesures péridialytiques. L’automesure devrait être recommandée en première ligne chez le patient HD (au moins une semaine/mois). Cependant, la MAPA fournit des informations uniques comme la PA nocturne et pourrait être proposée, idéalement une fois par an, chez tous les patients. [less ▲]

In the Tunisian south, the heated greenhouses are an important axis of development of agriculture thanks to the big geothermal potential of this zone. Currently, this sector suffers from several phytosanitary problems. In the last years, a new insect, Tuta absoluta, threaten the cultures of cultivated tomatoes in heated greenhouses. To improve control of T. absoluta, the effectiveness of pheromone traps (associated or not with a source of light) and luminous traps (associated or not with water, with limed buckets for limed covers) were compared. The results show that the traps with pheromones significantly catch more adults of T. absoluta compared to all the other types of traps (average number of trapped adults of T. absoluta = 73.4 (± 142)). The luminous traps associated with water, with limed buckets as with limed covers show, as for them, an intermediate effectiveness. In spite of this slightly less effectiveness, the luminous traps have the advantage of low costs of production as well as the advantage of simultaneously capturing males and females of T. absoluta.

Continuous-flow micro- and mesofluidic reactors come with inherent properties that can be advantageously utilized for expanding the horizon of preparative chemistry. Accurate control over local process parameters, even under extreme conditions, inherent safety, production homogeneity and seamless scale-up are amongst the most important assets of continuous-flow chemistry. Besides, flow chemistry enables the design of efficient multistep processes with significantly reduced footprints. In this note, we discuss some of the most fascinating aspects of continuous-flow micro- and mesofluidic reactors in the specific context of preparative organic chemistry. [less ▲]

Insects, particularly those belonging to the family Acrididae (grasshoppers), are commonly consumed as human food in many parts of the world. Grasshoppers of the species Chorthippus parallelus are abundantly found throughout Europe. However, these insects were not consumed by Europeans till now, but could possibly be used as human food, which is why we investigated their chemical composition. We found that they contain high level of proteins (69%), with an excellent amino acid profile and protein digestibility (97%). Furthermore, specimens of C. parallelus have an interesting fatty acids profile and minerals composition. Preliminary toxicity assessment indicates that these insects do not exhibit toxicity towards neutrophil cells (white blood cells). These data suggest that C. parallelus could be considered for human consumption. Rearing trials done during the study show that commercial rearing could be developed to produce sufficient biomass for sustaining human consumption. [less ▲]

Structural boundaries in ecosystems play an important role both in the context of seascape architecture, ecological processes and biodiversity. The Mediterranean Seagrass Posidonia oceanica (L.) Delile is considered an ecosystem engineer species, forming habitats of great ecological value and providing many ecosystem services. This study aims to (1) determine whether there are differences between seagrass-sand corridors edges and the adjacent continuous meadow, and (2) investigate whether anthropogenic pressures can cause disturbances in the measured parameters along the edges and the meadow. We have developed a multidisciplinary approach combining plant physiology, faunal canopy community studies and seagrass structural parameters characterization. We performed in situ chlorophyll fluorescence measurements using a Pulse Amplitude Modulated (Diving-PAM) fluorometry in order to assess the photosynthetic rate of the shoots. Vagile macrofauna of the leaf stratum was sampled by a hand-towed net, and the major taxonomic groups were sorted, counted, and identified. Meadow’s biometric measurements and the epiphytic biomass were also determined. Regarding edge-meadow matrix, results have shown highest differences on matrix structural parameters such as shoot density and shoot type proportions. Shoot density was found to decrease in edges considerably. We found c.a to 60 % plagiotropic shoots on edges while in continuous meadow orthotropics were predominant (up to 90 %). Howerver vagile-fauna population densities and diversity did not differ significantly among stations studied, neither by sites. Photosynthetic rate and leaf surface values also did not show changes between edges and continuous meadow. However, results did show that plagiotropic shoots had higher photosynthetic rate than orthotropics, and also that epiphyte abundance sorted out to be much higher (up to 54 %) on edges. [less ▲]

Summary : Two new classes of oral antidiabetic agents play an increasing role in the management of type 2 diabetes, dipeptidyl peptidase-4 (DPP-4) inhibitors (gliptins) and sodiumglucose cotransporters type 2 (SGLT2) inhibitors (gliflozins). After failure of a monotherapy with metformin (first pharmacological choice in type 2 diabetes), both may offer an alternative to the add-on of a sulphonylurea, especially in patients at risk of hypoglycaemia. However, the choice between a DPP-4 inhibitor and a SGLT2 inhibitor is not easy and should be oriented based upon the individual patient characteristics. The arguments in favour of one or another pharmacological class are discussed, considering a clinical case of a patient with coronary heart disease and type 2 diabetes not well controlled with metformin.

The pestivirus bovine viral diarrhea virus (BVDV) is known to bind to the CD46 molecule, which subsequently promotes entry of the virus. Mapping of the BVD-virion-binding site has shown that two peptides, 66EQIV69 and 82GQVLAL87, located on antiparallel beta sheets in the most distal complement control protein module (CCP1), provide the attachment platform. In the present study, we reveal new CD46-encoding transcripts that are predicted to encode CCP1-containing soluble forms. Further, we show that the serum of most adult cattle contains soluble CD46 (sCD46) and that a recombinant soluble isoform neutralizes BVDV infectivity in an in vitro assay. We have then established an ELISA for determination of plasma sCD46 in a large cohort of animals. Overall, serum sCD46 amounts to 8 ± 18 ng/mL (mean ± SD, n = 440), with a IC [95-105] ranging from 6,4 to 9,8 ng/mL and extreme values between 0 and 178 ng/mL. We found that sCD46 is not detectable in fetal and neonatal sera and that its plasma concentration increases progressively up to adulthood. We also detected high- and low-sCD46 performers and show that this phenotype does not depend of environment. As modern rearing techniques make it possible to disseminate genetically-determined phenotypes very quickly in a population, a large-scale study examining whether high-sCD46 animals provide epidemiological protection against BVDV infection and transmission should be undertaken.

Jeavons syndrome (JS) is an uncommon form of juvenile epilepsy. In some family affected by JS, the gene of importin-8 (IPO8) a member of karyopherin superfamily of proteins, has been found mutated. Karyopherin are known to regulate nucleo-cytoplasmic transport of many proteins. IPO8, a member of the β-karyopherin sub-family, is reported to control the transport Ago-2, c-Jun and Smad-4 for example, three proteins important for brain development. Here, we show that IPO8 is well expressed in mouse brain at embryonic stage. Moreover inhibition of IPO8 mRNA by shRNA in-utéro-electroporation (IUE), impairs early neuroblast migration as weel as IUE overexpression of mutated form of human IPO8. So, abnormal brain development due to IPO8 mutations could be at the origin of Jeavons Syndrome, Chilhood abscence evolving (CAE) and/or juvenile myoclonic epilepsy (JME). [less ▲]
