Effect of glucose on plasma concentrations of individual non-esterified fatty acids of non-diabetic and insulin-independent diabetic men.
The composition of plasma non-esterified fatty acids was investigated during glucose tolerance tests to determine changes in individual fatty acid concentrations after glucose administration and to determine whether differences existed between the individual fatty acid concentrations of maturity-onset diabetic and non-diabetic men. The mean fasting total nonesterified fatty acid concentration o...
متن کاملInsulin Acutely Inhibits Intestinal Lipoprotein Secretion in Humans in Part by Suppressing Plasma Free Fatty Acids
OBJECTIVE Intestinal lipoprotein production has recently been shown to be increased in insulin resistance, but it is not known whether it is regulated by insulin in humans. Here, we investigated the effect of acute hyperinsulinemia on intestinal (and hepatic) lipoprotein production in six healthy men in the presence and absence of concomitant suppression of plasma free fatty acids (FFAs). RES...
متن کاملPlasma glucose, non-esterified fatty acids and amino acids in Huntington's chorea.
1. The metabolic responses to an oral glucose tolerance test (100 g) and an intravenous insulin provocation test (0-1 i.u./kg) were studied in nine control subjects and nine patients with Huntington's chorea. 2. Plasma glucose responses to these stimuli were identical in both groups. 3. High fasting concentrations of non-esterified fatty acid (NEFA) were recorded in the choreic patients when co...
متن کاملFatty acids and insulin secretion.
It has long been recognized that acute elevation of non-esterified fatty acids (NEFA) stimulates insulin secretion to a moderate extent both in vitro and in vivo. The effects of longer-term exposure to elevated fatty acids have, however, been investigated only recently. Our own studies in the rat have documented the time dependence of NEFA effects, with inhibition of glucose-induced insulin sec...
متن کاملAcute elevation of plasma non-esterified fatty acids increases pulse wave velocity and induces peripheral vasodilation in humans in vivo.
Plasma NEFA (non-esterified fatty acid) concentrations are elevated in patients with obesity. In the present study we first aimed to provide an integral haemodynamic profile of elevated plasma NEFAs by the simultaneous assessment of blood pressure, pulse wave velocity, FBF (forearm blood flow) and sympathetic nervous system activity during acute elevation of NEFAs. Secondly, we hypothesized tha...
