Brief Summary
The purpose of this study is to determine whether chenodeoxycholic acid decreases de novo hepatic lipogenesis, hepatic fat content, hepatic triglyceride production and plasma triglyceride concentratio...
Detailed Description
Insulin resistance has been found to be the key pathophysiological factor of the metabolic syndrome and may precede the onset of impaired glucose tolerance, diabetes and dyslipidemia. Recently, nonalc...
