Theory and empirical studies suggest that cannibalism in age-structured populations can regulate recruitment depending on the intensity of intraspecific competition between cannibals and victims and the nature of the cannibalism window, i.e., which size classes interact as cannibals and victims. Here we report on a series of experiments that quantify that window for age-structured populations of salamander larvae and paedomorphic adults. We determined body size limits on cannibalism in microcosms and then the consumptive and nonconsumptive (injuries, foraging and activity, diet, growth) effects on victims in mesocosms with seminatural levels of habitat complexity and alternative prey. We found that cannibalism by the largest size classes (paedomorphs and >age 3+yr larvae) occurs mainly on young-of-the-year (YOY) victims. Surviving YOY and other small larvae had increased injuries, reduced activity levels, and reduced growth rates in the presence of cannibals. Data on YOY survival in an experiment in which we manipulated the density of paedomorphs combined with historical data on the number of cannibals in natural populations indicate that dominant cohorts of paedomorphs can cause observed recruitment failures. Dietary data indicate that ontogenetic shifts in diet should preclude strong intraspecific competition between YOY and cannibals in this species. Thus our results are consistent with previous empirical and theoretical work that suggests that recruitment regulation by cannibalism is most likely when YOY are vulnerable to cannibalism, but have low dietary overlap with cannibals. Understanding the role of cannibalism in regulating recruitment in salamander populations is timely given the widespread occurrences of amphibian decline. Previous studies have focused on extrinsic (including anthropogenic) factors that affect amphibian population dynamics, whereas the data presented here combined with long-term field observations suggest the potential for intrinsically driven population cycles.

The long pentraxin 3 (PTX3) plays an important role in host defence and its over-expression may contribute to airway injury. The aim of the present study was therefore to characterize in more detail PTX3 and its expression in the horses airway. Six healthy horses and six horses affected by recurrent airway obstruction (R.A.O.) were submitted to a dusty environment challenge. PTX3 DNA and cDNA were cloned and sequenced. PTX3 expression was evaluated by RT-qPCR, western blotting and immuno-histochemistry in bronchoalveolar lavage fluid (BALF) cells, BALF supernatant and bronchial epithelial cells. An alternative splicing of the second exon of PTX3 occurred, resulting in two forms of the protein: spliced (32 kDa) and full length (42 kDa). PTX3 was detected in BALF macrophages, neutrophils and bronchial epithelial cells. It was over-expressed in the BALF supernatant from R.A.O.-affected horses in crisis. However, dust was unable to induce PTX3 in BALF cells ex vivo, indicating that dust is an indirect inducer of PTX3. Dust exposure in-vivo induced PTX3 in BALF macrophages but there was no significant difference between healthy and R.A.O.-affected horses. Conversely, PTX3 was over-expressed in the bronchial epithelial cells from R.A.O-affected horses in crisis. These data indicate a differential regulatory mechanism in inflammatory and bronchial epithelial cells and offer therapeutically interesting perspectives. [less ▲]

Climatic variations happen at all time scales and since the origins of these variations are usually of very complex nature, climatic signals are indeed chaotic data. The identification of the cycles induced by the natural climatic variability is therefore a knotty problem, yet the knowing of these cycles is crucial to better understand and explain the climate (with interests for weather forecasting and climate change projections). Due to the non-stationary nature of the climatic time series, the simplest Fourier-based methods are inefficient for such applications (see e.g. Titchmarsh (1948)). This maybe explains why so few systematic spectral studies have been performed on the numerous datasets allowing to describe some aspects of the climate variability (e.g. climatic indices, temperature data). However, some recent studies (e.g. Matyasovszky (2009); Paluš & Novotná (2006)) show the existence of multi-year cycles in some specific climatic data. This shows that the emergence of new tools issued from signal analysis allows to extract sharper information from time series. Here, we use a wavelet-based methodology to detect cycles in air-surface temperatures obtained from worldwide weather stations, NCEP/NCAR reanalysis data, climatic indices and some paleoclimatic data. This technique reveals the existence of universal rhythms associated with the periods of 30 and 43 months. However, these cycles do not affect the temperature of the globe uniformly. The regions under the influence of the AO/NAO indices are influenced by a 30 months period cycle, while the areas related to the ENSO index are affected by a 43 months period cycle; as expected, the corresponding indices display the same cycle. We next show that the observed periods are statistically relevant. Finally, we consider some mechanisms that could induce such cycles. This chapter is based on the results obtained in Mabille & Nicolay (2009); Nicolay et al. (2009; 2010). [less ▲]

Structure, magnetic and magnetocaloric properties of poly- and nanocrystalline La0.5Ca0.5MnO3 manganites prepared by the citrate sol–gel method are studied in a broad temperature range. The Arrott plots show that the phase transition is of the second order. The cooling efficiency of 93–97 J/kg is found for the poly- and nanocrystalline samples. The relatively weaker magnetocaloric effect in nanocrystalline La0.5Ca0.5MnO3 is spread over temperature range almost three times broader than for the polycrystalline one. Charge ordering effects decay in manganites with grain sizes below 150 nm. [less ▲]

Le réseau microvasculaire de la peau joue des rôles physiologiques majeurs en oxygénant les tissus et en permettant des échanges thermiques finement régulés. Son parcours résistif et capacitif module les résistances périphériques au débit sanguin. La microvascularisation est sous l’influence de divers facteurs, mais globalement, elle semble presque immuable dans la peau saine. En revanche, certaines circonstances pathologiques engendrent des hyperplasies ou des hypoplasies vasculaires. Parfois aussi, le réseau semble garder son extension normale, mais sa structure intime est remaniée. Cette revue est un florilège d’aspects microscopiques associés à des perturbations majeures de la fonctionnalité vasculaire cutanée. [less ▲]

L'objectif du séminaire est d'amener les acteurs présents (éditeurs de chaînes, journalistes, politiques) à débattre de la question du cordon sanitaire et ainsi mettre à plat les différentes interprétations qui en sont données. A terme ces réflexions serviront de cadre au Collège d'avis du CSA qui devra revoir le règlement relatif aux programmes de radio et télévision en période électorale. Il s'agit de proposer des perspectives et questions par rapport au fait de donner ou non la parole à l'extrême droite dans les médias. Plus précisément, il s'agit d'interroger la responsabilité sociale et éditoriale des médias en éclairant le rôle que les médias et les journalistes jouent concrètement dans le succès électoral de l'extrême droite (à partir d'une analyse discursive de la couverture médiatique des présidentielles françaises de 2002).

À travers l’étude des termes grecs "iatreion" et "ergastèrion", cet article a pour objectif d’élucider non seulement les dénominations, mais aussi le statut et le fonctionnement des lieux d’exercice des médecins grecs. L’enquête se fonde sur les occurrences de ces deux mots relevées dans la documentation papyrologique, épigraphique et littéraire. Malgré un corpus réduit, la confrontation des diverses sources permet de donner une image assez précise de l’organisation et du rôle joué par le "iatreion", des maux qui y étaient soignés et des traitements qui y étaient appliqués par les médecins. Quant à l’"ergastèrion", trois témoignages, un papyrus et surtout deux inscriptions découvertes à Métaponte et Magnésie du Méandre, suggèrent l’utilisation exceptionnelle de ce terme dans un contexte médical ; il semble alors désigner un centre de soins de taille plus importante, où exerçaient plusieurs médecins.
