BACKGROUND Gene expression analysis is an invaluable tool in the study of diabetic glomerulosclerosis. The necessary denominator for the quantitative expression of a specific gene is the expression level of a second gene that is presumed to remain unchanged. Thus, it is critical that the stability of this housekeeping gene in diabetic glomeruli or in(More)
Left ventricular function, resting electrocardiograms, and Holter recordings were systematically examined in 25 consecutively hospitalized, seriously ill, emaciated adolescents with anorexia nervosa. We failed to observe serious arrhythmias, abnormal prolongation of QT interval, conduction abnormalities, or depression in left ventricular systolic function.
BACKGROUND Sulfonylurea agents exert their physiologic effects via binding to specific sulfonylurea receptors (SUR) in adenosine triphosphate-sensitive potassium (K(ATP)) channels. Mesangial cells express K(ATP) and respond to sulfonylureas by altering glucose metabolism, elevating intracellular calcium and contracting. A putative endogenous sulfonylurea,(More)
BACKGROUND Previously, we showed the expression of a unique sulfonylurea receptor (SUR) and its putative endogenous ligand, alpha-endosulfine, in mesangial cells and isolated glomeruli. Further, this ligand was up-regulated by high glucose concentration. To investigate the possible role of alpha-endosulfine up-regulation in diabetes, we administered(More)
Angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) therapy in hypertensive diabetic patients with macroalbuminuria, microalbuminuria, or normoalbuminuria has been repeatedly shown to improve cardiovascular mortality and reduce the decline in glomerular filtration rate. Renin-angiotensin-aldosterone system (RAAS) blockade in(More)
