Facteurs pronostiques impliqués dans l'insuffisance pancréatique exocrine canine (étude de 320 cas cliniques (2006-2012))

L insuffisance pancréatique exocrine est une maladie qui touche particulièrement le Berger Allemand, le Colleys, le Cavalier King Charles, le Chow Chow, l Eurasier et le Terre Neuve, causant diarrhée chronique et amaigrissement. L utilisation de gélules gastrorésistantes à haute activité enzymatique pour le traitement, améliore significativement la réponse thérapeutique. Par ailleurs, le pronostic est moins favorable s il existe une hypovitaminose B12 qui doit être impérativement corrigée par voie parentérale. Le suivi régulier des chiens atteints d IPE ainsi que la bonne observance du traitement sont indispensables à la gestion de cette maladie chronique nécessitant un traitement couteux à vie.NANTES-Ecole Nat.Vétérinaire (441092302) / SudocSudocFranceF

Diversity of nematode assemblages along a Mediterranean deep-sea transect.

The diversity of the nematode assemblages along a Mediterranean transect off Calvi, Corsica, Mediterranean Sea (depth range 160 to 1220 m) was very high. There was no clear trend in species diversity with station depth, and diversity at the station located on the continental shelf was not markedly lower than that at the deep-sea stations. However, diversity decreased with increasing depth into the sediment. As with the macrofauna, nematode assemblages in the Mediterranean is explained by a slight dominance of some species, while no species are dominant in the Bay of Biscay. Generic (between-genus) diversity was much higher than the average species diversity within genera, indicating that the high overall species diversity was not caused by large numbers of closely related co-existing species. Since species abundances are low, mate location for amphimictically reproducing species can impose an important metabolic cost on the organism. However, there are no indications that parthenogenesis is important in deep-sea nematodes

Cultural Studies and Critical Literacies

This article introduces a special issue on the topic of Cultural Studies and Critical Literacies. The collection of articles is drawn from the central theme of the inaugural Summer Institute of the Association for Cultural Studies: to explore the implications of studying literacy by combining perspectives from cultural studies and (critical) literacy studies. The issue also serves to map current trends in cultural studies by sharing and extending some of the discussions that took place at the Institute with the larger cultural studies community. In this introduction, we will revisit work undertaken at the intersection of literacy studies and cultural studies, including the phenomenon of multiliteracies, in order to set the scene for our collection of articles that focuses on different contemporary ‘uses’ of literacy

Penicillium and Talaromyces spp. emerging pathogens in dogs since 1990s

Abstract Penicillium and Talaromyces spp. are environmental saprophytic molds rarely encountered as infectious agents in humans and animals. This article summarizes the clinical features, treatment, and outcomes of proven infections caused by Penicillium or Talaromyces in four dogs in France. Two dogs had disseminated infections, while the other two had a localized form. All dogs had positive histopathological results showing the presence of hyaline septate hyphae and a positive fungal culture with typical Penicillium conidiophores. Talaromyces georgiensis (n = 1), Penicillium labradorum (n = 2), and Penicillium from section Ramosa series Raistrickiorum (n = 1), were identified based on Internal Transcribed Spacer (ITS) Sanger sequencing. The dogs were initially treated with ketoconazole or itraconazole. Second-line treatment was initiated in three dogs, but after several relapses, the prognosis remained poor. Since the 1990s, 18 cases of Penicillium or Talaromyces infections in dogs have been described worldwide. This series of four reports brings new cases to those already reported in the literature, which are probably underestimated in the world

Limitation of size by hypoxia in the fruit fly Drosophila melanogaster

The size of an organism is of fundamental importance in all biological processes. It dictates many of the critical interactions and physical factors that delimit the envelope within which an organism can grow. We investigated the effects of reduced oxygen on size and development in the fruit fly Drosophila melanogaster, and showed that limiting the oxygen in the environment limits both whole animal and cell size. When oxygen levels were reduced from 20% in nitrogen to 15%, 10% and 7.5%, there was a linear decrease in both male and female mass. Both cell size and cell number decreased in low oxygen, but changes in cell size accounted for a larger proportion of the overall change in fly size. Cell numbers decreased by a maximum of 11% between flies reared in 20% oxygen and those reared in 7.5% oxygen, whereas cell surface area decreased by 17%. Low oxygen levels increased development time and mortality, but reduced fecundity. Reducing the level of oxygen available significantly slowed development times, with flies reared in 10% oxygen emerging on average 1.5 days later than those in 20% oxygen. The effect of oxygen on size is reversible during embryonic and larval development up to the pupal stage, when final size is set
