L’Auteur propose ici un panorama de l'artisanat et de l'économie du fer autour des rivages français de la Méditerranée, sur la longue durée. La démarche archéologique intègre une approche archéométrique spécialement adaptée à l’analyse de la sidérurgie ancienne, utilisant métallographie et pétrographie. La question est traitée dans son ensemble, non seulement sur la base des connaissances déjà acquises, à partir d’inventaires bibliographiques précis, mais aussi à partir des études inédites et détaillées de douze contextes métallurgiques « témoins », significatifs de problématiques propres. Ils sont documentés par l’ensemble des données archéologiques et, spécialement, sur la base d’une description rigoureuse des aménagements, du tri de près de 28 000 pièces métallurgiques – objets et scories – et de l’analyse archéométrique de 169 d’entre elles. L’ouvrage se structure autour des trois grandes activités qui se dégagent de la chaîne opératoire de la métallurgie du fer directe : la production du matériau fer (la réduction directe du minerai), la fabrication des objets (forgeage) et le commerce du matériau fer sous une forme semi-finie (la circulation des demi-produits). Ainsi, à travers l’évolution de ces trois types d’activités économiques, il met en évidence les choix et les comportements qui ont été adoptés pour un même exercice, des cadres antiques à l’orée de la réforme carolingienne pour, finalement, contribuer à une meilleure connaissance de l’économie et de la société entre l’époque romaine et le début du Moyen Âge en Gaule du Sud.

An HPLC/UV method was first optimized for the separation and quantitation of human acylated and unacylated (or des-acyl) ghrelin from aqueous solutions. This method was validated by an original approach using accuracy profiles based on tolerance intervals for the total error measurement. The concentration range that achieved adequate accuracy extended from 1.85 to 59.30microM and 1.93 to 61.60microM for acylated and unacylated ghrelin, respectively. Then, optimal temperature, pH and buffer for sample storage were determined. Unacylated ghrelin was found to be stable in all conditions tested. At 37 degrees C acylated ghrelin was stable at pH 4 but unstable at pH 7.4, the main degradation product was unacylated ghrelin. Finally, this validated HPLC/UV method was used to evaluate the binding of acylated and unacylated ghrelin to liposomes. [less ▲]

The aim of this study was to investigate the influence of isoenergetic substitution between the three energy delivering macronutrients in pre-starter diets on performance and intermediary nutrient metabolism in broiler chickens. From hatch until 5 days of age, 600 chicks, collected during peak of hatch, were fed one of the three experimental pre-starter diets with isoenergetic (13 MJ metabolisable energy/kg) substitutions between fat (43 vs. 108 g/kg), protein (126 vs. 240 g/kg) and carbohydrates (391 vs. 510 g/kg). After 5 days, commercial grower and finisher diets were provided. Pre-starter composition influenced body weight until slaughter age, although not statistically verifiable. Broilers fed the low protein (LP) pre-starter had the lowest body weight in relation to chickens on the low carbohydrate or low fat pre-starter diet. After hatch, chicks on the LP pre-starter diet were able to use the residual yolk sac more rapidly to fulfil their protein requirement, which is reflected in small intestine and liver development. Also, plasma metabolite levels were influenced mostly by the LP pre-starter, indicating that the main focus for the requirements of newly hatched chicks should be on proteins. Furthermore, optimal nutrition during the first day's post-hatch should take into account the contribution of the yolk. [less ▲]

In this study, a cell based lattice free modelling framework is proposed to study cell aggregate behaviour in bone tissue engineering applications. The model encompasses cell-to-cell and cell environment interactions such as adhesion, repulsion and drag forces. Oxygen, nutrients, waste products, growth factors and inhibitors are explicitly represented in the model influencing cellular behaviour. Furthermore, a model for cell metabolism is incorporated representing the basic enzymic reactions of glycolysis and the Krebs cycle. Various types of cell death such as necrosis, apoptosis and anoikis are implemented. Finally, an explicit model of the cell cycle controls the proliferation process, taking into account the presence or absence of various metabolites, sufficient space and mechanical stress. Several examples are presented demonstrating the potential of the modelling framework. The behaviour of a synchronised cell aggregate under ideal circumstances is simulated, clearly showing the different stages of the cell cycle and the resulting growth of the aggregate. Also the difference in aggregate development under ideal (normoxic) and hypoxic conditions is simulated, showing hypoxia induced necrosis mainly in the centre of the aggregate grown under hypoxic conditions. The next step in this research will be the application of this modelling framework to specific experimental set-ups for bone tissue engineering applications. (C) 2009 Elsevier Ltd.

Primary cutaneous lymphomas are distinguished by singular clinical, histological and prognostic features that are not shared by other lymphomas originating from the lymphoid tissues. This review is an update of the current concepts about the biology, diagnosis and treatment of mycosis fungoides, the most frequent entity among the primary cutaneous T cell lymphomas. It is currently established that mycosis fungoides originates from T lymphocytes normally homing the dermis. Such a situation implies that treatments at least in the initial stages of the disease, should primarily target the skin without searching for an impact on internal lymphoid tissues. [less ▲]

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.

This article presents a new interpretation of the temple M's content placed in the so-called sanctuary of Asklepios in Emporion. The sculptures are related to an inscription of the area and also to a sigilado glass and chandeliers that come from the Roman city. All this proves the presence of an Egyptian worship in Emporion more complex than earlier. [less ▲]

Host protection to helminth infection requires IL-4Rα signalling and the establishment of finely regulated Th2 responses. In the present study, the role of IL-4Rα-responsive T cells in Schistosoma mansoni egg-induced inflammation was investigated. Egg-induced inflammation in IL-4Rα-responsive BALB/c mice was accompanied with Th2-biased responses, whereas T cell-specific IL-4R-deficient BALB/c mice (iLckcreIl4ra−/lox) developed Th1-biased responses with heightened inflammation. The proportion of Foxp3+ Tregs in the draining lymph node of control mice did not correlate with the control of inflammation and was reduced in comparison to T cell-specific IL-4R-deficient mice. This was due to IL-4-mediated inhibition of CD4+Foxp3+ Tregs conversion, demonstrated in adoptively transferred Rag2−/− mice. Interestingly, reduced footpad swelling in Il4ra−/lox mice was associated with the induction of IL-4 and IL-10-secreting CD4+CD25−CD103+Foxp3− cells, confirmed in S. mansoni infection studies. Transfer of IL-4Rα-responsive CD4+CD25−CD103+ cells, but not CD4+CD25high or CD4+CD25−CD103− cells, controlled inflammation in iLckcreIl4ra−/lox mice. It finally turned out that the control of inflammation depended on IL-10, as transferred CD4+CD25−CD103+ cells from IL-10-deficient mice were not able to effectively downregulate inflammation. Together, these results demonstrate that IL-4 signalling in T cells inhibits Foxp3+ Tregs in vivo and promotes CD4+CD25−CD103+Foxp3− cells that control S. mansoni egg-induced inflammation via IL-10.

We prove that the equivalence between Vershik’s standardness criterion and the I-cosiness criterion for a filtration in discrete, negative time, holds separately for each random variable. This gives a strengthening and a more direct proof of the global equivalence between these two criteria. We also provide more elementary original propositions on Vershik’s standardness criterion, while emphasizing that similar statements for I-cosiness are sometimes not so obvious. [less ▲]

This study evaluated the contribution of implementation intentions over the constructs of the theory of planned behaviour in testing a confirmatory model explaining the relationships between antecedents of academic achievement for university students. It was found that the effects of intention to perform and its classic antecedents on exams performance were mediated by implementation intentions with a considerable increase of amount of explained variance above the contribution of the constructs of planned behaviour theory. This paper is organized as follows. We first introduce the construct of intention, particularly in the context of the well documented model of the theory of planned behaviour (TPB). The limitation of this model will be explained and a basic distinction it does not consider will be pointed to: forming an intention vs. implementing it. Then we present the Heckhausen and Gollwitzer's Action Phases Model (APM) and the construct of implementation intention. The results of experimental and correlational researches on the predictive power of this construct, especially in the educational domain, will be discussed. Thirdly, we propose an integrative model which fills the gap between TPB and performance by introducing implementation intentions from unwanted inner states. Fourthly, we give the results of an experimental research aiming in testing this model conducted in an educational settings and using a confirmatory design (Structural Equation Modelling). In the end, we insist on the implication of these results for students. [less ▲]
