The effect of gemfibrozil on postprandial lipoprotein metabolism was investigated in a 12-week, randomized, double-blind, placebo-controlled trial in 20 non-insulin-dependent diabetic patients with moderate hypertriglyceridemia. The patients were given a meal containing 78 g of fat and 345,000 units of vitamin A to label chylomicrons and their remnants. Plasma obtained at various times during t...

INTRODUCTION Metabolic syndrome is a powerful predictor of cardiovascular events independent of overt diabetes. Dietary restriction and weight loss modify metabolic syndrome components. This study addresses whether combination pharmacologic therapy focused on dyslipidemia provides additional benefit. METHODS This study examines the effect of 1 year of gemfibrozil, niacin and cholestyramine th...

Treatment decisions related to disease prevention are often based on two conventional and related assumptions. First, an intervention-induced change in a surrogate marker (such as high-density lipoprotein [HDL]-cholesterol) in the desired direction translates into health benefits (such as reduction in coronary events). Second, it is unimportant which interventions are used to alter surrogate ma...

The ability of a drug to cause clinically significant drug-drug interactions due to direct or metabolism-dependent inhibition of cytochrome P450 (CYP) can generally be predicted from in vitro studies with human liver microsomes (HLM) or recombinant CYP enzymes, as recommended by the FDA and other regulatory agencies. This review highlights some examples of system-dependent inhibition of CYP and...

Objectives: Familial chylomicronemia syndrome is characterized by massive accumulation of plasma chylomicrons, which typically results from an absolute deficiency of lipoprotein lipase (LPL). Chylomicronemia in pregnancy is a rare, but serious clinical problem and can be found in patients with underlying molecular defects in the LPL gene. We report the course and treatment of an 18 yr-old primi...

Obesity is associated with cognitive impairments. Long-term mechanisms for this association include consequences of hyperglycemia, dyslipidemia, or other factors comprising metabolic syndrome X. We found that hypertriglyceridemia, the main dyslipidemia of metabolic syndrome X, is in part responsible for the leptin resistance seen in obesity. Here we determined whether triglycerides have an imme...

Peroxisome proliferators induce stearoyl-CoA desaturase activity (EC 1.14.99.5) in liver [Kawashima, Y., Hanioka, N., Matsumura, M. & Kozuka, H. (1983) Biochim. Biophys. Acta 752, 259-264]. We analyzed the changes in stearoyl-CoA desaturase 1 (SCD1) mRNA to further define the molecular mechanism for the induction of stearoyl-CoA desaturase by peroxisome proliferators. SCD1 mRNA was analyzed fro...

This research was purposely to study and determine the physicochemical characteristics, sensory hypocholesterolemic effects of purple sweet potato bread made from flour, starch, fiber-rich flour starch processing waste on white male species Wistar rats conducted in vivo. used a non-factorial randomized block design model with treatment 100% standard feed, 25% mixture bread, combination 50% heal...
