A crucial step in the understanding of vocal behavior of birds is to be able to classify calls in the repertoire into meaningful types. Methods developed to this aim are limited either because of human subjectivity or because of methodological issues. The present study investigated whether a feature generation system could categorize vocalizations of a bird species automatically and effectively. This procedure was applied to vocalizations of African gray parrots, known for their capacity to reproduce almost any sound of their environment. Outcomes of the feature generation approach agreed well with a much more labor-intensive process of a human expert classifying based on spectrographic representation, while clearly out-performing other automated methods. The method brings significant improvements in precision over commonly used bioacoustical analyses. As such, the method enlarges the scope of automated, acoustics-based sound classification. [less ▲]

Dipeptidyl peptidase-4 (DPP-4) inhibitors offer new options for the management of type 2 diabetes. Direct comparisons with active glucose-lowering comparators in drug-naive patients have demonstrated that DPP-4 inhibitors exert slightly less pronounced HbA(1c) reduction than metformin (with the advantage of better gastrointestinal tolerability) and similar glucose-lowering effects as with a thiazolidinedione (TZD; with the advantage of no weight gain). In metformin-treated patients, gliptins were associated with similar HbA(1c) reductions compared with a sulphonylurea (SU; with the advantage of no weight gain, considerably fewer hypoglycaemic episodes and no need for titration) and a TZD (with the advantage of no weight gain and better overall tolerability). DPP-4 inhibitors also exert clinically relevant glucose-lowering effects compared with a placebo in patients treated with SU or TZD (of potential interest when metformin is either not tolerated or contraindicated), and as oral triple therapy with a good tolerability profile when added to a metformin-SU or pioglitazone-SU combination. Several clinical trials also showed a consistent reduction in HbA(1c) when DPP-4 inhibitors were added to basal insulin therapy, with no increased risk of hypoglycaemia. Because of the complex pathophysiology of type 2 diabetes and the complementary actions of glucose-lowering agents, initial combination of a DPP-4 inhibitor with either metformin or a glitazone may be applied in drug-naive patients, resulting in greater efficacy and similar safety compared with either drug as monotherapy. However, DPP-4 inhibitors were less effective than GLP-1 receptor agonists for reducing HbA(1c) and body weight, but offer the advantage of being easier to use (oral instead of injected administration) and lower in cost. Only one head-to-head trial demonstrated the non-inferiority of saxagliptin vs sitagliptin. Clearly, more trials of direct comparisons between different incretin-based therapies are needed. Because of their pharmacokinetic characteristics, pharmacodynamic properties (glucose-dependent glucose-lowering effect) and good overall tolerability profile, DPP-4 inhibitors may have a key role to play in patients with renal impairment and in the elderly. The role of DPP-4 inhibitors in the therapeutic armamentarium of type 2 diabetes is rapidly evolving as their potential strengths and weaknesses become better defined mainly through controlled clinical trials.

Many animals respond to predation by releasing alarm signals that warn other individuals of the presence of danger in order to reduce the success of predators. While alarm signals may be visual or auditory as well as chemical, alarm pheromones are common, especially among insects and aquatic organisms. In this paper we discuss our current understanding of chemical alarm signaling in a variety of animal groups (including social and pre-social insects, marine invertebrates, fish, and mammals). We also briefly discuss the exploitation of alarm pheromones as foraging cues for natural enemies. [less ▲]

Objective: To assess current habits for surgical hand preparation amongst veterinary surgical specialists and to compare data with current guidelines for hand asepsis techniques. Study design: Survey of veterinary surgical specialists Sample Population: Diplomates of the American (ACVS) and European Colleges of Veterinary Surgeons (ECVS). Methods: An internet based survey of hand preparation methods before surgical procedures was conducted of 1300 listed ACVS and ECVS Diplomates. Results: A 42.6% response rate was obtained. Approximately 80% of respondents use disinfecting soaps as a primary method for hand antisepsis. Of those, 81% use chlorhexidine based scrubs and 7% use a neutral soap followed by a hydroalcoholic solution. Conclusions: Contrary to current recommendations of the World Health Organization and scientific evidence supporting use of hydro-alcoholic rubs for presurgical hand preparation, veterinary surgical specialists still use surgical scrub solutions containing disinfecting soaps.

Evénement majeur, aux retombées sociales, économiques et politiques évidentes, le grand mouvement de grèves de l’hiver 1960-1961 a également été observé par l’étranger et, singulièrement, par la France officielle. Tout en exposant brièvement le regard porté sur les grèves par le Quai d’Orsay, les consulats et l’ambassade de France, cette contribution s’attache surtout à étudier dans quelle mesure la perception des revendications politiques et économiques wallonnes par la France officielle a pu être modifiée, à court et moyen terme, par les grandes grèves et comment les mouvements wallons, à commencer par le Mouvement Populaire Wallon (MPW), ont espéré capitaliser sur ces grèves pour mieux diffuser leur message outre-Quiévrain et y nouer des contacts. Elle envisage enfin les démarches entreprises par la Belgique pour contrer cet "entrisme" du mouvement wallon. [less ▲]

Low-density lipoprotein receptor-related protein-1 (LRP-1) is a plasma membrane scavenger and signaling receptor, composed of a large ligand-binding subunit (515-kDa α-chain) linked to a shorter transmembrane subunit (85-kDa β-chain). LRP-1 cell-surface level and function are controlled by proteolytic shedding of its ectodomain. Here, we identified ectodomain sheddases in human HT1080 cells and demonstrated regulation of the cleavage by cholesterol by comparing the classical fibroblastoid type with a spontaneous epithelioid variant, enriched ∼2-fold in cholesterol. Two membrane-associated metalloproteinases were involved in LRP-1 shedding: a disintegrin and metalloproteinase-12 (ADAM-12) and membrane-type 1 matrix metalloproteinase (MT1-MMP). Although both variants expressed similar levels of LRP-1, ADAM-12, MT1-MMP, and specific tissue inhibitor of metalloproteinases-2 (TIMP-2), LRP-1 shedding from epithelioid cells was ∼4-fold lower than from fibroblastoid cells. Release of the ectodomain was triggered by cholesterol depletion in epithelioid cells and impaired by cholesterol overload in fibroblastoid cells. Modulation of LRP-1 shedding on clearance was reflected by accumulation of gelatinases (MMP-2 and MMP-9) in the medium. We conclude that cholesterol exerts an important control on LRP-1 levels and function at the plasma membrane by modulating shedding of its ectodomain, and therefore represents a novel regulator of extracellular proteolytic activities.-Selvais, C., D'Auria, L., Tyteca, D., Perrot, G, Lemoine, P., Troeberg, L., Dedieu, S., Noël, A., Nagase, H., Henriet, P., Courtoy, P.

Endocrine system disruption has become a subject of great interest over the last few decades, since it has become evident that natural and also synthetic substances can mimic or reduce the activity of endogenous hormones. Compounds with estrogenic activity are an important family of potential endocrine disruptors that have to be monitored either in the food chain or in the environment. Estrogens are known to induce or promote hormonal dependent cancers, to reduce sperm counts and fertility in men and generate the feminization of exposed wildlife populations. The rapid screening of unwanted chemicals in the food chain is beset by difficulties. The number of toxic compounds is very large and no universal method can cope with their diversity. In this work, emergent differential proteomic techniques are used to discover a set of biomarkers for the development of a multiple estrogen contaminants screening test. [less ▲]
