Aims: Serotonergic pathways in the central nervous system (CNS) are activated in the regulation of food intake and body weight. We hypothesized that adipocytes, like other cells of mesenchymal origin, possess serotonin receptors and thus could be regulated by peripherally circulating serotonin.
Methods:In vivo studies: four Sprague–Dawley rats were given daily serotonin (5HT) injections subcutaneously...
To study the mechanisms responsible for the hypotriglyceridemic effect of marine oils, we monitored the effects of high dietary intake of n−3 PUFA on hepatic and muscular β-oxidation, plasma leptin concentration, leptin receptor gene expression, and in vivo insulin action. Two groups of male Wistar rats were fed either a high-fat diet [28% (w/w) of saturated fat] or a high-fat diet containing 10%...
Background. In many pre-eclamptic women the placentation process seems to be disturbed. Our objective was to investigate if disturbed placentation in pre-eclamptic women may be recognized in early second trimester as altered plasma levels of factors involved in the formation of the uteroplacental unit.Methods. In a prospective study of 2190 pregnant women we compared plasma leptin, transforming growth...
Abstract: We investigated the effects of acute starvation on mitogen-induced T-cell activation and Th1/Th2 cytokine responses in rheumatoid arthritis (RA) patients. Ten RA patients with active disease underwent a 7-day fast followed by a 2-week refeeding period. Immunological, hormonal, laboratory and clinical evaluations were carried out on days 0, 7 and 21. Using flow cytometry, mitogen-stimulated...
