Several hypotheses concerning consequences of selenium deficiency on iodine metabolism can be proposed on the basis of experimental studies in rats and from epidemiological and experimental studies in humans. By decreasing intracellular GSH peroxidase activity, selenium deficiency may increase hydrogen peroxide (H2O2) supply and lead over several weeks to(More)
OBJECTIVE To investigate the ovarian renin-angiotensin system (RAS) during severe ovarian hyperstimulation syndrome (OHSS). DESIGN Simultaneous sampling of blood and ascitic or peritoneal fluid (PF) during therapeutic paracentesis or laparoscopy. SETTING University Hospital. PATIENTS Twelve patients were investigated: three patients presenting severe(More)
The pathophysiology of ovarian hyperstimulation syndrome (OHSS) remains unclear. Several lines of evidence indicate that OHSS is associated with a stimulation of the renin-angiotensin system (RAS), but its functional significance as well as its role in the pathogenesis of the syndrome are not yet determined. OHSS is associated with high plasma and ascitic(More)
OBJECTIVE To investigate the implications of the ovarian renin-angiotensin system (RAS) in the pathophysiology of the ovarian hyperstimulation syndrome (OHSS) in relation to gonadotropin stimulation and early pregnancy. DESIGN A controlled clinical study comparing blood and simultaneously sampled peritoneal fluid (PF) from patients with severe OHSS and(More)
Local variations in the ovarian renin-angiotensin system were investigated in peritoneal fluid (PF) during normal menstrual cycles and after ovarian stimulation with gonadotropins. PF was collected either during laparoscopy or by transvaginal aspiration before ovocyte retrieval for in vitro fertilization. Renin activity (RA) and angiotensin II(More)
In thyroidectomized rats, the activity of FAD-linked glycerophosphate dehydrogenase was severely diminished in liver homogenates but not affected significantly in pancreatic islet homogenates, whilst the activity of 2-ketoglutarate dehydrogenase was decreased modestly in both liver and islet homogenates. Likewise, in intact islets of thyroidectomized rats,(More)
The proximal promoter regions of the thyroglobulin gene from man, beef, dog and rat were compared by transient expression in primary cultured dog thyrocytes. All four promoter regions were able to control properly the expression of a reporter gene in response to cyclic AMP stimulation. Surprisingly, despite extensive sequence conservation, the(More)
