Le cannibalisme est issu d’une déformation linguistique de la terminologie Arawak (Amérindiens des Antilles) caribal qui signifie courageux. Christophe Colomb l’emploie pour désigner les Indiens des Caraïbes réputés pour être des mangeurs d’hommes. Le cannibalisme est largement répandu au sein du règne animal. Sa pratique au sein de l’espèce humaine remonte au Paléolithique et persiste encore dans certaines sociétés actuelles, bien qu’elle ne répond pas exclusivement à des besoins alimentaires comme chez les autres espèces animales. Au regard de sa large distribution, il y a lieu de s’interroger sur les causes, origines et avantages évolutifs de ce comportement au sein du règne animal. Le cannibalisme est induit soit par des facteurs écologiques directement liés à une insuffisance des ressources alimentaires, à de fortes densités d’individus et à une hétérogénéité structurale de la population, soit par des facteurs sociaux comme des besoins de reproduction, ou des contraintes de soins parentaux face à une progéniture trop nombreuse. Les avantages de ce comportement sont les gains nutritionnel et énergétique, les gains de territoire pour vivre et se développer. Par contre, les inconvénients résident dans la réduction des effectifs et de la variabilité génétique de la population, ainsi que dans la possibilité de transmission de parasites, virus et de maladies.

Case reports are the most accessible publications to the medical student or the practitioner. The appropriate selection of the clinical case that deserves publication is an important first step in the process. Afterwards, the report of the case requests much attention, as far as both content and presentation are concerned. The key-message emerging from the clinical case should be emphasized and supported by a clear-cut argumentation. Such an exercise, which might appear difficult at first glance, represents a valuable training for further more complex scientific publications. Here we give some practical advices to help the student or the practitioner who would like to present or publish a case report. [less ▲]

This is a retrospective analysis of medical records in 4 Belgian diabetes centres of 3 cohorts of patients with type 2 diabetes, with data available, respectively, after 3 months < or =163 patients exposed), 6 months (n=77) and 9 months (n=28) with exenatide therapy. This analysis mainly focuses on the 3 and 6 month cohorts. The mean HbA1 level at baseline averaged 9% and decreased by -1.3% and -1.4% at 3 and 6 months, respectively (-1.5% at 9 months). Neither the duration of diabetes nor initial body weight did influence the metabolic response. The decrease in HbA(1c) at 6 months was greater in patients with higher baseline HbA(1c):-0.5%, -1.4% and -2.4% for a baseline HbA(1c) level <8%, 8-10% and >10%, respectively. At 6 months, the composite criterion of a reduction of HbA(1c) by >1% or a final level <7% was reached by 69% of the cohort. Body weight decreased continuously over time, with a mean reduction of -2.1 kg at 3 months and -3.0 kg at 6 months (-4.9 kg at 9 months). The greater the baseline body weight, the greater the weight loss at final evaluation. Minor nausea and more rarely vomiting were observed, essentially during the first months of exenatide treatment. According to this observational study in routine practice, exenatide may be a valuable alternative to insulin for intensification of treatment of patients with type 2 diabetes after failure of oral drug combination, independently of baseline HbA(1c), body weight and duration of diabetes.

ABSTRACT: BACKGROUND: Oviduct epithelial cells (OEC) co-culture promotes in vitro fertilization (IVF) in human, bovine and porcine species, but no data are available from equine species. Yet, despite numerous attempts, equine IVF rates remain low. Our first aim was to verify a beneficial effect of the OEC on equine IVF. In mammals, oviductal proteins have been shown to interact with gametes and play a role in fertilization. Thus, our second aim was to identify the proteins involved in fertilization in the horse. Methods & results In the first experiment, we co-incubated fresh equine spermatozoa treated with calcium ionophore and in vitro matured equine oocytes with or without porcine OEC. We showed that the presence of OEC increases the IVF rates. In the subsequent experiments, we co-incubated equine gametes with OEC and we showed that the IVF rates were not significantly different between 1) gametes co-incubated with equine vs porcine OEC, 2) intact cumulus-oocyte complexes vs denuded oocytes, 3) OEC previously stimulated with human Chorionic Gonadotropin, Luteinizing Hormone and/or oestradiol vs non stimulated OEC, 4) in vivo vs in vitro matured oocytes. In order to identify the proteins responsible for the positive effect of OEC, we first searched for the presence of the genes encoding oviductin, osteopontin and atrial natriuretic peptide A (ANP A) in the equine genome. We showed that the genes coding for osteopontin and ANP A are present. But the one for oviductin either has become a pseudogene during evolution of horse genome or has been not well annotated in horse genome sequence. We then showed that osteopontin and ANP A proteins are present in the equine oviduct using a surface plasmon resonance biosensor, and we analyzed their expression during oestrus cycle by Western blot. Finally, we co-incubated equine gametes with or without purified osteopontin or synthesized ANP A. No significant effect of osteopontin or ANP A was observed, though osteopontin slightly increased the IVF rates. CONCLUSION: Our study shows a beneficial effect of homologous and heterologous oviduct cells on equine IVF rates, though the rates remain low. Furthers studies are necessary to identify the proteins involved. We showed that the surface plasmon resonance technique is efficient and powerful to analyze molecular interactions during fertilization. [less ▲]

la Province de Luxembourg a souhaité que soit menée une réflexion sereine, aussi scientifique et objective que possible, sur les avenirs possibles de l’élevage chez nous. Deux questions fondamentales présidaient la démarche : - au niveau « micro-économique », y a-t-il un avenir chez nous pour l’agriculture ? Autrement dit, est-ce un métier d’avenir, faut-il encore encourager les jeunes à s’y engager ? Comment peuvent-ils espérer gagner leur vie en embrassant cette profession passionnante mais difficile ? - au niveau « macro-économique », comment pouvons-nous influer sur le cours des choses pour préserver la diversité des activités économiques sur le territoire de la province ? Que pouvons-nous faire pour que l’agriculture puisse rester un secteur créateur d’emploi et par ailleurs un moteur de notre vitalité rurale ? Traduites en objet de recherche, ces questions devenaient : - identifier les facteurs qui a court et moyen termes sont susceptibles de conditionner le devenir de l'agriculture ; - identifier les formes et les conditions de viabilité (économique mais aussi acceptation par les intéressés) susceptibles de favoriser l'adaptation de l'agriculture à ces facteurs de changement ; - définir précisément les enjeux économiques et sociaux (qu’y a-t-il à perdre et à gagner dans chaque avenir identifié ?) ; - amener, d’une manière participative, les acteurs concernés (agriculteurs, mais aussi pouvoirs locaux, etc.) à adopter un état d’esprit positif face aux changements proposés afin de leur permettre d’intégrer ces changements.
