This study consists in identifying and testing potential inorganic substitutes to carbon based materials commonly used as adsorbents for the removal of organic pollutants such as dioxins and furans released from Municipal Solid Waste Incinerators (MSWI). Although carbon materials enable to reach the current regulation in terms of dioxins and furans emissions, they exhibit a potential auto ignition risk when present in hot flue gases. Here, the adsorption potential of carbon based products is compared to the one of some inorganic materials. Chlorobenzene was chosen as a reference molecule to compare the removal performance of the different adsorbents. This comparison was based on the determination of the adsorption energies derived from temperature programmed desorption (TPD) experiments. In the first part of this study, five inorganic materials were selected according to their chlorobenzene adsorption performance compared to those of carbon based products currently used to remove micropollutants from MSWI flue gases. In the second part of the study, the influence of the inlet concentration of adsorbate on the adsorption potential of sorbents is investigated. Actually, the organic compound concentration was decreased in order to be closer to those met in MSWI. Furthermore, the adsorption experiments were performed with other adsorbates whose molecular mass or chlorine content are higher. Thanks to these adsorption results a new organic free formulation has been proposed for the removal of micropollutants. Tests carried out on an industrial scale, demonstrated that this product enables to reach the current norm concerning dioxins and furans emissions. (C) 2004 Elsevier Ltd. All rights reserved.

During more than 20 years, estrogens replacement therapy (ERT) has been consistently regarded as the first choice for prevention of trabecular and cortical bone loss in postmenopausal women. However, there are more doubts upon the unequivocal demonstration of the anti-fracture efficacy of ERT, at the spine and hip. Controlled clinical trials and systematic reviews were retrieved, using Medline 1970-2002 and EMBASE 1980-2002. There is a convergent body of evidence that estrogens could significantly reduce the risk of vertebral and non-vertebral fractures, providing this treatment is started early after the menopause and pursued indefinitely. In the recent perspective of the published studies, reevaluating the non-skeletal benefits and harms of ERT in post-menopausal women, other chemical entities might be better options to be used for the specific purpose of preventing or treating post-menopausal osteoporosis.

Tachycardias arise from an arrhythmogenic substrate triggered by a random factor (generally an extrasystole) and modulated by the autonomic nervous system. The three components are interactive, but their intensity and conjunction vary continuously. During the last decade, major achievements have been made to clarify definition and classification of data reported in the literature, helping our understanding of the mechanisms of ventricular arrhythmias. Nowadays, the pathophysiology of cardiac arrhythmias is well-known at the cellular and molecular ion channel activity. The progress of epidemiology and molecular genetics have allowed a better knowledge of the genotype-phenotype correlation in young patients presenting syncopes due to torsades de pointes or polymorphic ventricular tachychardia episodes which may degenerate into ventricular fibrillation and cause sudden death. The data of numerous large prospective randomised studies have led to more rational treatments with the progressive withdrawal of class I antiarrhythmics and their replacement by betablocking agents. The surgical approach of ventricular tachycardia has been overcome by the automatic implantable defibrillator and in some well-defined clinical situations, catheter ablation is used. [less ▲]

Glutathione S-transferases (GST) play an important role in the detoxification of many substances including organic pollutants and plant secondary metabolites. We compared the GST of two syrphid species, the aphidophagous Syrphus ribesii and the saprophagous Myathropa florea to assess the relation between feeding type and GST patterns. Differences between the GST of the hoverfly species were observed after purification by affinity chromatography, SDS-PAGE and kinetic studies. While the specific activities of the purified enzymes were different, the purification yields were similar. The variation in specific activities was related to the presence of different isoenzymes in both syrphid species by SDS-PAGE. While two bands of 24 and 32 kDa were observed for M. florea, one more band of 26 kDa was present in S. ribesii. When a range of substrate and glutathione concentrations was tested, differences in Km and Vmax between the glutathione S-transferases from both hoverfly species were also observed. These results are discussed in terms of adaptations to the feeding habit and the habitat of the two syrphid species. [less ▲]

Glycerol-3-phosphate (glycerol-3P) is a primary substrate for triacylglycerol synthesis. In the present study, changes in the levels of glycerol-3P during rape (Brassica napus L.) seed development and the influence of manipulating glycerol-3P levels on triacylglycerol synthesis were investigated. (i) Glycerol-3P levels were high in young seeds and decreased during seed development at 30 and 40 days after flowering (DAF), when lipid accumulation was maximal. (ii) To manipulate glycerol-3P levels in planta, various concentrations of glycerol were injected directly into 30-DAF seeds, which remained otherwise intact within their siliques and attached to the plant. Injection of 0-10 nmol glycerol led to a progressive increase in seed glycerol-3P levels within 28 h. (iii). Increased levels of glycerol-3P were accompanied by an increase in the flux of injected [14C]sucrose into total lipids and triacylglycerol, whereas fluxes to organic acids, amino acids, starch, protein and cell walls were not affected. (iv) When [14C]acetate was injected into seeds, label incorporation into total lipids and triacylglycerol increased progressively with increasing glycerol-3P levels. (v) There was a strong correlation between the level of glycerol-3P and the incorporation of injected [14C]acetate and [14C]sucrose into triacylglycerol. (v) The results provide evidence that the prevailing levels of glycerol-3P co-limit triacylglycerol synthesis in developing rape seeds. [less ▲]
