The feeding of a diet rich in unsaturated fats to rabbits produced no significant alteration of the serum cholesterol level, while the feeding of a diet rich in saturated fats produced an elevation of the serum cholesterol without the development of experimental atherosclerosis. The addition of unsaturated fnts to a diet rich in cholesterol failed to prevent hypercholesterolemia and experimenta...

BACKGROUND AND AIM Fatty acids acutely stimulate GLP-1 secretion from L-cells in vivo. However, a high fat diet has been shown to reduce the density of L-cells in the mouse intestine and a positive correlation has been indicated between L-cell number and GLP-1 secretion. Thus, the mechanism of fatty acid-stimulated GLP-1 secretion, potential effects of long-term exposure to elevated levels of d...

background: liver fatty acid-binding protein (l-fabp) is the main cytosolic binding site for long chain fatty acids in hepatocytes. fabps enhance the uptake of fatty acids into the cell by increasing their concentration due to decreasing concentration of unbound fatty acids inside the cell. objectives: the aim of this study was to evaluate the effects of dietary unsaturated to saturated fatty a...

A Monte Carlo dynamics (MCD) scheme has been applied in a study of the effects of unsaturated double bonds on the internal conformational dynamics and orientational order of hydrocarbon chains arranged in a monolayer on the surface of an impenetrable interface. The MCD algorithm makes use of the high coordination {2 1 0) lattice for the representation of both sp3 and sp2 valence states of the c...

Liver specific deletion of the tumor suppressor phosphatase and tensin homologue deleted on chromosome 10 (PTEN) induces steatosis and hypersensitivity to insulin. Saturated fatty acids, which induce endoplasmic reticulum stress and cell death, appear to increase PTEN, whereas unsaturated fatty acids which do not induce endoplasmic reticulum stress or cell death reduce this protein. In the pres...

principal function of insulin in the liver is to suppress glucose production when blood glucose concentrations increase. This process is impaired in hepatic insulin resistance and contributes to postprandial hyperglycemia. The development of hepatic insulin resistance is very closely linked to non alcoholic fatty liver disease (NAFLD), and is a major factor in the pathogenesis of type 2 diabete...

1. Rat liver mitochondria oxidizing [16-14C]palmitoylcarnitine accumulate saturated long-chain thiester intermediates which may be detected by radio-g.1.c.2. Time-courses of intermediate accumulation display no product-precursor relationships and the end product, measured as [14C]citrate, is produced without a detectable initial lag. 3. A short pulse of [16-14C]palmitoylcarnitine followed by un...
