Administration of clofibrate to adult mice (20-25 mg of clofibrate/day) increased liver glycerophosphate acyltransferase (EC 2.3.1.15) activity by 2.3-fold within 24 h. This increased glycerophosphate acyltransferase activity was mainly localized in the liver microsomal fraction. Three other hypolipidemic drugs, i.e. Bezafibrate (Boehringer Mannheim Co.), Gemfibrozil (Warner-Lambert Co.) and Wy...

A rise in extracellular D-glucose concentration causes in pancreatic islets a preferential stimulation of aerobic, relative to total, glycolysis. The possible participation in such a phenomenon of a glucose-induced and Ca(2+)-dependent activation of FAD-glycerophosphate dehydrogenase was investigated. In islet homogenates, the activity of the mitochondrial and Ca(2+)-responsive FAD-glycerophosp...

These studies were initiated to ascertain whether, in rat brown adipose tissue as in white, lipolysis is a forerunner and fatty acid esterification an energy-consuming accompaniment of the increased oxygen uptake induced by catecholamines. No evidence could be obtained with brown adipose tissue slices to support this premise. Respiratory processes in homogenates of brown adipose tissue were the...

background periodontium may be able to respond to injuries by regeneration via the function of stem cells. objectives this study sought to assess the differentiation of human periodontal ligament stem cells (pdlscs) into osteoblasts in standard osteogenic medium and in a medium supplemented with 1,25-dihydroxyvitamin d3 (calcitriol). materials and methods in this experimental study, pdlscs were...
