This paper presents the results of slurry polymerisation of ethylene that has been initiated by an Al/Ti/Mg-alcohol supported catalyst. Special attention has been paid to the effects of hydrogen, catalyst composition and addition of an α-olefin on catalyst efficiency, molecular weight, crystallinity, and physico-mechanical properties of the final polyolefin. The efficiency of this Al/Ti/Mg catalyst, molecular weight and melting temperature of the formed High Density Polyethylene (HDPE) has been found to decrease as the partial pressure of hydrogen is increased. In parallel, crystallinity and elongation at break of HDPE increase. The composition of this Al/Ti/Mg catalyst has a marked effect on catalyst efficiency, e.g. decrease in the Ti relative content results in an improved efficiency from 86 to 7942 kg PE g-l Ti h-1 as the Mg/Ti molar ratio is increased from 1 to 333. Copolymerisation with 1-octene has also been investigated. When ethylene polymerisation is carried out with this Al/Ti/Mg catalyst at a Mg/Ti ratio of 333, addition of the cr-olefin is responsible for a decrease in the polymerisation rate, which is typical of a negative 'comonomer' effect. This effect is still more pronounced in the presence of H2. Comparison with other catalytic systems has been made in order to understand the role played by the cr-olefin and/or hydrogen on the catalyst efficiency and the physico-mechanical properties of the resulting polyolefins.

Besides classical etiologies of hyperprolactinaemia (pregnancy, pharmacological treatments, pituitary or hypothalamic perturbations), another less known cause may explain a spectacular idiopathic elevation of plasma concentrations of prolactin hormone. Macroprolactinaemia is characterized by the presence of a circulating high molecular weight complex of prolactin with an immunoglobulin G. In this article, we report the cases of 3 female patients for whom size exclusion chromatography technique permitted to give a precise biological diagnosis and to avoid heavy, expensive, time consuming and unnecessary clinical investigations or therapeutic actions. Patients with macroprolactinaemia do not exhibit clinical features of classical hyperprolactinaemia, notably as regard to menstrual and fertility disturbances. [less ▲]

Etiopathogenesis of type 2 diabetes is complex and still partially unknown. Its etiology is determined by the interaction of genetic and environmental factors. The genetic contribution is important, but has a polygenic origin. Obesity, especially when fat mass is preferably located in the abdomen, is the main predisposing factor for type 2 diabetes, and almost 80% of diabetic patients are overweight or obese. The diabetogenic effect of obesity is due to the capacity of excessive fat mass to induce or aggravate insulin resistance. Increasing lack of physical activity is also a contributing factor as it increases insulin resistance. As far as pathophysiology is concerned, the development of type 2 diabetes results from the coexistence of abnormalities of insulin secretion and insulin action. Insulin secretory dysfunction, whose underlying mechanism remains poorly understood, is characterized by a relative defect in circulating insulin levels of variable severity. Resistance to insulin action is located in the liver (increased hepatic glucose production), in the skeletal muscle (decreased muscular glucose uptake) and in the adipose tissue (exaggerated lipolysis with elevated plasma free fatty acids). Changes in life-style habits (weight reduction, regular physical activity) are able to prevent or delay the development of type 2 diabetes. [less ▲]

The etioplast plastid type of dark-grown angiosperms is defined by the accumulation of the chlorophyll (Chi) precursor protochlorophyllide (Pchlide) and the presence of the paracrystalline prolamellar body (PLB) membrane. Both features correlate with the presence of NADFH:Pchlide oxidoreductase (FOR), a light-dependent enzyme that reduces photoactive Pchlide-F655 to chlorophyllide and plays a key role in chloroplast differentiation during greening. Two differentially expressed and regulated FOR enzymes, FORA and FORB, have recently been discovered in angiosperms. To investigate the hypothesis that etioplast differentiation requires FORA, we have constitutively overexpressed PORA and FORB in the Arabidopsis wild type and in the constitutive photomorphogenic cop1-18 (previously det340) mutant, which is deficient in the PLB and Pchlide-F655. In both genetic backgrounds, FOR overexpression increased PLB size, the ratio of Pchlide-F655 to nonphotoactive Pchl[ide]-F632, and the amount of Pchlide-F655. Dramatically, restoration of either FORA or FORB to the cop1 mutant led to the formation of etioplasts containing an extensive PLB and large amounts of photoactive Pchlide-F655. [less ▲]

A l’heure où l’Union européenne prépare un texte qui pourrait rendre l’étiquetage nutritionnel obligatoire d’ici 2014, le présent article réalise un tour d’horizon des législations et pratiques en vigueur au sein de l’Union européenne en matière d’étiquetage nutritionnel. Les différents systèmes de représentation ainsi que les différents types de valeurs de référence sont présentés et discutés. La liste des avantages et inconvénients de chaque option possible sert de base à une réflexion sur les limites des pratiques actuelles et permet de proposer quelques pistes d’amélioration. Les différentes informations présentées visent à la fois à aider à une meilleure compréhension de l’étiquetage nutritionnel par le public non averti, mais aussi à permettre aux professionnels du secteur de poser leurs choix de manière éclairée.
