Development of vasculature and mRNA expression of 17 pro- or antiangiogenic factors were studied during adipose tissue development in nutritionally induced or genetically determined murine obesity models. Subcutaneous (SC) and gonadal (GON) fat pads were harvested from male C57Bl/6 mice kept on standard chow [standard fat diet (SFD)] or on high-fat diet for 0-15 wk and from male ob/ob mice kept on SFD. Ob/ob mice and C57Bl/6 mice on high-fat diet had significantly larger SC and GON fat pads, accompanied by significantly higher blood content, increased total blood vessel volume, and higher number of proliferating cells. mRNA and protein levels of angiopoietin (Ang)-1 were down-regulated, whereas those of thrombospondin-1 were up-regulated in developing adipose tissue in both obesity models. Ang-1 mRNA levels correlated negatively with adipose tissue weight in the early phase of nutritionally induced obesity as well as in genetically determined obesity. Placental growth factor and Ang-2 expression were increased in SC adipose tissue of ob/ob mice, and thrombospondin-2 was increased in both their SC and GON fat pads. mRNA levels of vascular endothelial growth factor (VEGF)-A isoforms VEGF-B, VEGF-C, VEGF receptor-1, -2, and -3, and neuropilin-1 were not markedly modulated by obesity. This modulation of angiogenic factors during development of adipose tissue supports their important functional role in obesity. [less ▲]

This paper presents an intermediate approach between parametric shape optimization and topology optimization. It is based on using the recent Level Set description of the geometry and the novel eXtended Finite Element Method (XFEM). The method takes benefit of the fixed mesh work using X-FEM and of the curves smoothness of the Level Set description. Design variables are shape parameters of basic geometric features. The number of design variables of this formulation is small whereas various global and local constraints can be considered. The Level Set description allows to modify the connectivity of the structure as geometric features can merge or separate from each other. However no new entity can be introduced. A central problem that is investigated here is the sensitivity analysis and the way it can be carried out efficiently. Numerical applications revisit the classical elliptical hole benchmark from shape optimization. [less ▲]

Communication présentée lors du LXIième congrès de la Société Française de Phoniatrie et des Pathologies de la Communication; Paris, le 9 octobre 2005. Our knowledge of vocal fold structure has profoundly evolved since the description by M.Hirano in 1974 of the laminar organization of the connective tissue of the human vocal fold , the lamina propria. The molecular composition of the extracellular matrix (ECM) of the lamina propria is essential in determining the viscoelastic properties of the tissue. This is particularly true in the superficial layer of the lamina propria ( also called Reinke’s space). With the epithelium, Reinke’s space constitutes the vocal fold main vibrator. In normal subjects, the jelly like structure of the Reinke’s space is due to a very loose fibrous scaffolding and to a balance between the interstitial proteins of the ECM : proteoglycans like decorin and hyaluronic acid and glycoproteins like fibronectin. Vibratory trauma leads , in disease states , to molecular modification of the extracellular matrix of Reinke’s space resulting in benign cordal lesions like nodules, submucosal fibrosis and vocal folds scars. Improving the knowledge of the homeostasis of Reinke’s space ECM can lead to improvement of the therapeutic and prevention strategies of vocal fold benign lesions. The main histologic and viscoelastic characteristics, as well as surgical treatment of cordal nodular lesions and scars are described. The recent researches in the field of regeneration of Reinke’s space are evoked. Rappel des connaissances de la microstructure cordale normale( et en particulier de la structure laminaire de la corde vocale ainsi que la répartition particulière des protéo- et glycosaminoglycans) , de l'altération de celle-ci en cas de nodule cordal et de cicatrice cordale.

Les maladies cardiovasculaires constituent la première cause de décès chez les patients dialysés chroniques. Parmi les facteurs impliqués on trouve les anomalies du métabolisme phosphocalcique. Le but de cette étude est de relier l'incidence de nouvelles calcifications et des décès (22%, n=18) avec les paramètres du métabolisme phosphocalcique au travers d'une étude prospective portant sur les années 2003-2004. L'établissement d'un score de calcification vasculaire précoce (dès la prise en charge en dialyse) permettra un suivi étroit et une adaptation prudente du traitement contrôlant le métaboisme phosphocalcique.

Il y a peu, j'étais au Niger, un pays dont, pour une fois, on parlait abondamment car trois millions de personnes souffraient de malnutrition et risquaient d'y laisser la vie à cause d'une saison des pluies déficitaire dans un pays déjà gangrené par la désertification. Et, après des mois d'indifférence puis de tergiversations, les autres pays du grand village planétaire décidèrent de sauver ces moins nantis. In extremis. Notre mission était d'organiser au mieux la distribution de l'aide alimentaire. Et nous voici déjà confrontés à un problème inattendu : l'insuffisance de véhicules pour transporter les vivres dans les villages les plus reculés et difficiles d'accès. Les quelques 4x4 rapidement réquisitionnés ne suffisaient pas. Un soir de vent de sable, j'ai discuté avec les locaux autour du thé. Au détour de notre conversation, je leur ai appris que nous avions en Belgique de gros bolides aux quatre roues motrices appelés « Touareg ». Etonnés, les touaregs, ceux d'appellation d'origine contrôlée, ont observé le silence et m'ont longuement regardé droit dans les yeux. La lune était notre seule lumière, le vent était retombé, et ce silence n'était perturbé que par les pleurs de quelques enfants affamés ne trouvant pas le sommeil. Le plus vieux d'entre eux esquissa alors un large sourire et me dit : « c'est que vos routes sont en très mauvais état ». Alors, je leur ai dissimulé que nous ne connaissions pas les pistes sinon via les images du Paris-Dakar. J'ai gardé pour moi que les routes ravagées par les ravines ou les nids d'autruches comblés par des immondices pour les rendre un temps soit peu carrossables n'existaient pas chez nous. Je ne leur ai pas dit non plus que Bruxelles comptait plus de véhicules tout-terrain que le Niger. Non, je n'ai rien dit de tout cela. J'ai ébauché à mon tour un large sourire et j'ai goûté au deuxième thé, légèrement sucré, le thé de l'amitié, comme ils disent... [less ▲]

The objective of this study was to evaluate the zootechnical performances (average daily gain, pH of the loin at 45 minutes after slaughter and meat percentage) of Stress-negative Piétrain (Piétrain RéHal) in industrial cross. The effects of genotype (CC, CT TT and Com), sex (male and female), year of fattening (from 1996 to 2004) and cage (37 cages) on the study parameters have been estimated. The observed values ranged from 574.5 to 668.1 g for the average daily gain, from 6.05 to 6.42 for the pH of loin at 45 minutes post mortem, and from 60.10 to 64.29% for the lean percentage. The average daily gain of pig of the commercial line (Com) was higher (from + 87.2 to + 93.7 g), but inversely presented a carcass lean percentage lower than those of CC, CT and TT. The pH of the loin at 45 minutes post mortem of pig CT and Com was similar (6.3 and 6.2 respectively) and hold an intermediate position between CC (6.4) and TT (6.0), even though this value of genotype TT was lower. The male presented a superior growth rate (+ 35.4 g) but a carcass lean percentage inferior (- 1.82 %) to the female one. The sex was not a significant effect on the pH of loin at 45 minutes post mortem (p > 0.05). The fattening year had a significant effect (p < 0.001) on all studied parameters however, without any particularly trend. [less ▲]
