Relying on methods other than the determination of turnover rate of triglyceride from the curve of plasma triglyceride radioactivity after administration of labeled precursor, we have confirmed that the endogenous hypertriglyceridemia induced by estrogenization of the chick is accompanied by increased production of triglyceride. Chicks estrogenized with diethylstilbestrol became grossly hypertr...

Insulin resistance syndrome, also referred to as the metabolic syndrome or syndrome X, refers to a constellation of common metabolic and cardiovascular disorders (e.g. obesity, type 2 diabetes mellitus, hypertension, and dyslipidemia), which are all cardiovascular risk factors. Insulin resistance can be induced by fructose-rich diet in rats. We investigated the effect of vanadyl sulfate (0.2 mg...

Hypertriglyceridemic subjects were fed diets in which dietary fat calories were held constant, but carbohydrate calories were varied. Three subjects with fasting chylomicronemia (Type V) were given less carbohydrate and four subjects without fasting chylomicronemia (Type IV) were fed diets with more calories as carbohydrate. The restricted carbohydrate intake led to disappearance of chylomicron...

The liver secretes triglyceride-rich VLDLs, and the triglycerides in these particles are taken up by peripheral tissues, mainly heart, skeletal muscle, and adipose tissue. Blocking hepatic VLDL secretion interferes with the delivery of liver-derived triglycerides to peripheral tissues and results in an accumulation of triglycerides in the liver. However, it is unclear how interfering with hepat...

Chronic renal failure (CRF) is associated with hypertriglyceridemia and elevated plasma VLDL and IDL concentrations. These events can be due to either increased production or depressed catabolism of triglyceride-rich lipoproteins. Several studies have documented downregulation of lipoprotein lipase, hepatic triglyceride lipase, and the VLDL receptor, leading to depressed clearance and elevated ...

An interaction between smoking and antipsychotic medications could potentially affect treatment efficacy promote metabolic side effects. We investigated the contribution of status towards Positive Negative Syndrome Scale (PANSS) scores syndrome- related parameters (plasma lipid glucose concentrations, body mass index) among two groups unmedicated patients with psychosis from Croatian population...

In an earlier study it was shown that retinyl palmitate appeared to be a satisfactory label for the core of chylomicrons and their remnants. When chylomicrons were endogenously labeled with retinyl palmitate and pulse-injected into healthy donors, retinyl palmitate was cleared from plasma by a first order process. Its fractional decay constant was very similar to the fractional catabolic rate o...

Changes in VLDL triglyceride and VLDL apo B production were determined semiquantitatively in healthy young men by examining the effect of altering plasma insulin and/or FFA levels on the change in the slopes of the specific activity of VLDL [3H]triglyceride glycerol or the 131I-VLDL apo B versus time curves. In one study (n = 8) insulin was infused for 5 h using the euglycemic hyperinsulinemic ...

Patients with type 2 diabetes are frequently dyslipidemic or hypertriglyceridemic. To assess whether increased intestinal triglyceride input leads to elevated fasting and postprandial triglycerides in type 2 diabetes, we used the codon 54 polymorphism of the fatty acid-binding protein 2 gene, which results in the substitution of threonine (Thr) for alanine and is associated with increased intes...
