Journal ArticleDOI
Role of free fatty acids and insulin in determining free fatty acid and lipid oxidation in man.
TL;DR: When the plasma FFA concentration is maintained unchanged by heparin infusion, insulin has no direct effect on FFA turnover and disposal, which suggests that plasma F FA oxidation is primarily determined by the plasmaFFA concentration, while net lipid oxidation is regulated by both the Plasma FFA and the insulin level.
Journal ArticleDOI
Effect of physiologic hyperinsulinemia on glucose and lipid metabolism in cirrhosis.
TL;DR: It is suggested that chronic hyperinsulinism may be responsible for the insulin resistance observed in cirrhosis and with low-dose insulin infusion, plasma FFA oxidation and turnover failed to suppress normally in cirrhotics.
Journal ArticleDOI
Glucose and insulin metabolism in cirrhosis.
TL;DR: The hyperinsulinemia results from three abnormalities: diminished hepatic extraction, portosystemic/intrahepatic shunting, and enhanced insulin secretion, which reflects a disturbance in glycogen synthesis.
Journal ArticleDOI
Glucose metabolism in cirrhosis: a review with some perspectives for the future.
Journal ArticleDOI
Leucine metabolism in IDDM: Role of insulin and substrate availability
TL;DR: In conclusion, insulin-mediated glucose metabolism is severely impaired in subjects with both poorly controlled and well-controlled IDDM, whereas the effect of acute insulin infusion on leucine turnover is normal, and combined hyperaminoacidemia/hyperinsulinemia stimulated NOLD to a similar extent in both IDDM and control subjects.
