Different animal models have been used to study the effects of prenatal protein undernutrition and the mechanisms by which these occur. In mammals, the maternal diet is manipulated, exerting both direct nutritional and indirect hormonal effects. Chicken embryos develop independent from the hen in the egg. Therefore, in the chicken, the direct effects of protein deficiency by albumen removal early during incubation can be examined. Prenatal protein undernutrition was established in layer-type eggs by the partial replacement of albumen by saline at embryonic day 1 (albumen-deprived group), compared to a mock-treated sham and a non-treated control group. At hatch, survival of the albumen-deprived group was lower compared to the control and sham group due to increased early mortality by the manipulation. No treatment differences in yolk-free body weight or yolk weight could be detected. The water content of the yolk was reduced, whereas the water content of the carcass was increased in the albumen-deprived group, compared to the control group, indicating less uptake of nutrients from the yolk. At embryonic day 16, 20 and at hatch, plasma triiodothyronine (T3), corticosterone, lactate or glucose concentrations and hepatic glycogen content were not affected by treatment. At embryonic day 20, the plasma thyroxine (T4) concentrations of the albumen-deprived embryos was reduced compared to the control group, indicating a decreased metabolic rate. Screening for differential protein expression in the liver at hatch using two-dimensional difference gel electrophoresis revealed not only changed abundance of proteins important for amino acid metabolism, but also of enzymes related to energy and glucose metabolism. Interestingly, GLUT1, a glucose transporter, and PCK2 and FBP1, two out of three regulatory enzymes of the gluconeogenesis were dysregulated. No parallel differences in gene expressions causing the differences in protein abundance could be detected pointing to post-transcriptional or post-translational regulation of the observed differences.

Two previously unknown variable stars in the crowded central region of the globular cluster NGC 6981 are presented. The observations were made using the electron multiplying CCD (EMCCD) camera at the Danish 1.54 m Telescope at La Silla, Chile. The two variableswere not previously detected by conventional CCD imaging because of their proximity to a bright star. This discovery demonstrates that EMCCDs are a powerful tool for performing high-precision time-series photometry in crowded fields and near bright stars, especially when combined with difference image analysis. Based on data collected by MiNDSTEp with the Danish 1.54 m telescope. [less ▲]

In less than ten years, a business property market has emerged in Wallonia. This market first concerned offices and retail units (a sector not studied in this paper) and, more recently, semi-industrial establishments. Its development is largely related to the creation of new demands in physical units, environment and accessibility, as well as in location choices, at both sub-regional and local scales. It has been favoured by the arrival of new property stakeholders from Belgium and abroad (developers, investors and property agents), as well as by public authorities (the Walloon Region and, more importantly, supra-communal, economic development agencies). The emergence of this market is related to the accentuation of territorial contrasts as property development projects usually reinforce strong area [less ▲]

La fièvre catarrhale ovine (FCO) qui s'est développée depuis 2006 en Europe du Nord présente un profil pathologique nouveau, en particulier chez les bovins. L'infection a notamment causé des troubles de la fertilité et de la reproduction. Les conséquences cliniques de l'infection transplacentaire vont de l'avortement aux anomalies congénitales (hydranencéphalie). Les veaux infectés in utero peuvent naître viropositifs, avec des statuts diagnostiques difficiles à interpréter. L'infection expérimentale du veau avec le virus de sérotype 8 reproduit une symptomatologie similaire à celle observée sur le terrain. L'émergence du virus de sérotupe 6 aux Pays-Bas, de même que celle du virus Toggenburg en Suisse posent des questions sur l'évolution du profil pathologique de l'infection des bovins par différent sérotypes ou variants du virus de la FCO.

Un nombre croissant de pays du sud font figure de "gagnants" de la globalisation. C'est le cas de l'Afrique du Sud, du Brésil, de la Chine, de l'Inde ou du Mexique. Alors que d'autres, à l'instar de la Russie, semblent confirmer leur retour comme puissance politique à vocation planétaire. Ces pays dit du "BRICSAM" apparaissent comme des acteurs plus influents et porteurs d'un potentiel de développement économique capable d'occasionner une transformation radicale de l'état du monde et des rapportés de forces dans l'arène politique et économique mondiale. Dès lors l'essor de nouvelles puissances pose la question de la multipolarité de l'ordre mondial. [less ▲]
