Dans le cadre des différents thèmes de travail proposés aux membres de la commission de Toxicologie Clinique de la SFTA, une étude est réalisée sur l'identification et la quantification simultanée de 12 benzodiazépines dans le plasma. L'objectif est de tester la robustesse d'une technique d'extraction en l'imposant aux différents participants, les conditions chromatographiques de séparation et le mode de détection restant libres, fonctions de l'équipement de chaque laboratoire. L'étude a été réalisée sur une période de 2 mois et demi. Deux échantillons tests de plasmas surchargés avec 12 benzodiazépines à des concentrations thérapeutiques ou supra-thérapeutiques sont adressés à chaque centre d'investigation en vue de leur évaluation. La technique d'extraction utilise un mélange d'hexane / dichlorométhane en milieu tamponné (pH 9.2) et le loflazépate d'éthyle comme standard interne. Une méthode CLHP avec détecteur à barrette de diode est proposée à défaut par le laboratoire coordonnateur aux participants ne disposant pas de technique d'analyse. Sur les 11 participants, 10 utilisent une technique CLHP, un seul une technique CPG. Parmi les techniques CLHP, 2 d'entre elles associent un détecteur de masse, 7 un détecteur à barrette de diodes, 1 un détecteur UV. La technique CPG est associée à un détecteur de masse. L'analyse des résultats montre que la technique d'extraction proposée a été testée avec succès par 8/11 des participants : 4/11 laboratoires sans erreur et 4/11 laboratoires avec 1 ou 2 résultats exclus. Par contre, 3/11 laboratoires ont rencontré des difficultés majeures : un site par la survenue d'émulsions lors du traitement des échantillons tests (plasmas lyophilisés à reconstituer), un site par manque de temps et d'expérience, le troisième mettant en cause le choix du standard interne en technique CPG, le loflazépate d'éthyle n'ayant pas fait l'objet d'une étude préalable par cette technique.

Le « Plan Mobilisateur TIC » (PMTIC) est né en 2002 de l'initiative de la Ministre wallonne de l'Emploi et de la Formation, Mme Marie Arena. Ce plan est destiné à sensibiliser et à former aux TIC une partie du public des demandeurs d'emploi. Il s'inscrit dans la perspective du sommet de Lisbonne sur la société de la connaissance et dans le contrat d'avenir de la Région wallonne (2002).[...] Le Laboratoire de Soutien à l’Enseignement Télématique (LabSET) de l’Université de Liège s’est vu confier la coordination pédagogique des 109 opérateurs de formation retenus dans le cadre du PMTIC. Cette mission de coordination pédagogique recouvre des tâches nombreuses parmi lesquelles nous pouvons distinguer notamment un suivi sur le terrain des opérateurs, la mise en place de journées de formation continue des formateurs et le développement de modules de formation disponibles en ligne pour les stagiaires.

Corns and callosities are the expression of a peculiar aspect of mecanobiology of the foot. They are more frequent with ageing, particularly in women. These lesions represent a risk factor for the diabetic foot. Prevention measures are important to follow in predisposed individuals. Several medicinal and non medicinal treatments have proven their efficacy. [less ▲]

Baseline Ankle-Brachial Blood Pressure Index (ABI base) was measured in 85 chronic hemodialysis (HD) patients in 2005, giving a 41% prevalence of peripheral arterial disease (ABI < 0.9). The index was measured 1 year later (ABI 1 year) in 69 BD for whom both screening values were available. The evolution of ABI, 1 year apart, was analyzed in relation to major other cardiovascular (CV) risk factors such as hypertension (lIT), pulse pressure (PP), pulse wave velocity (PWV), phosphocalcic metabolism, and lipids.

Three different approaches for the estimation of uncertainty measurements using the same analytical method were compared, namely validation, robustness and inter-laboratory studies. The uncertainty obtained with the robustness study! predicted well the uncertainty of the inter-laboratory study. On the other hand, the uncertainty estimation obtained with the validation study is lower than those obtained with the two other approaches but is still acceptable as long as the analytical method will be used in a single laboratory.

We are interested in investigating the function of Hoxc8 in skeletogenesis during mouse development. Previous studies have shown that deregulation of Hoxc8 expression in the mouse leads to several skeletal defects, such as homeotic transformation in the thoracic vertebrae, abnormal development of the rib cage, and overproliferation of chondrocytes in the hypertrophic area. By deleting a crucial enhancer of Hoxc8 in vivo, we found that precise temporal expression of Hoxc8 is important for determining the correct identity of the vertebral column in early embryos. We also identified downstream targets of Hoxc8 relevant to osteoblast differentiation at later developmental stages. [less ▲]

The rabbit is an essential model in scientific research, particularly in the study of cardiovascular diseases such as hypertension and atherosclerosis and for the investigation of the osteoarticular system. Due to the fact that various factors (environmental, microbial, stress, pain.) can influence data obtained from experiments, special care must be given to housing conditions. Sensory enrichment (olfactive, auditive, visual or tactile stimuli) and physical enrichment (nutritional and social stimuli) allow rabbits to express specific behaviours and reduce stereotypies. This synthesis reminds of the importance of these factors and gives to the researcher some ways to control them. [less ▲]

Several studies have suggested that acetaldehyde, the first product of ethanol metabolism, is involved in the locomotor stimulant effects of ethanol in mice, although it has never been formally tested whether acetaldehyde injected directly into the brain of mice has stimulant properties. Recently, it was also shown in rats that both ethanol and acetaldehyde can induce opposite locomotor effects according to the route of administration. Whereas peripheral administrations of ethanol and acetaldehyde induced locomotor depressant effects, their infusions directly into the brain produced locomotor stimulation. The aim of the present study was to characterize in mice the locomotor effects of ethanol and acetaldehyde injected either peripherally by the intraperitoneal route or centrally into the brain ventricles. Additionally, the effects of ethanol and acetaldehyde were compared in two strains of mice known for their differential sensitivity to the locomotor effects of ethanol, namely Swiss and C57BL/6J mice. Ethanol induced a biphasic effect on locomotor activity in Swiss mice, with stimulant effects at low to moderate doses and depressant effects at higher doses. Such a profile of effects was observed whatever the route of administration, peripheral or central. In C57BL/6J mice, ethanol only induced monophasic depressant effects. In this mouse strain, no evidence of the stimulant effects of ethanol was found after either an i.p. or an i.c.v. administration of ethanol. In contrast to ethanol, acetaldehyde yielded only depressant effects in both strains of mice after both peripheral and central administrations. These results indicate that the route of administration does not alter the locomotor effects of ethanol and acetaldehyde in mice. Additionally, the present study shows that the stimulant properties of acetaldehyde, even after direct infusion into the brain, are not as obvious as previously speculated. [less ▲]

This paper will illustrate the choice of the alloying elements and their content in the current grade. By using sophisticated laboratory examination techniques such as differential thermal analysis, scanning electron microscopy and image analysis, the metallurgical parameters of Aurora grade will be described and compared to those of the Kosmos grade. An attempt will also be made to connect all our laboratory results to the good behaviour of the alloy in operation in the early stands of Hot Strip Mills. [less ▲]

In spring 2000, three events--two political statements by Bill Clinton and Tony Blair and a breakthrough announcement by Celera Genomics--had a major impact on biotechnology stocks. We analyze their effects over a comprehensive set of biopharmaceutical companies, using a composite return-generating model with an industry-specific patent-based factor. Our results show that stocks can be clustered according to their responsiveness to political and scientific events. Furthermore, we emphasize different impacts on the market value of intangible assets for each cluster, suggesting that growth options are valued with different criteria for therapeutics, and technology-based subsectors.
