Exaggerated postprandial lipemia is associated with coronary heart disease and type II diabetes, yet few studies have examined the effect of sequential meals on lipoprotein metabolism. We have used 13C-labeled fatty acids to trace the incorporation of fatty acid derived from a meal into apolipoprotein B-100 (apoB-100)-containing lipoproteins and plasma nonesterified fatty acids (NEFA) following...

BACKGROUND AND PURPOSE It has been suggested that a postprandial accumulation of triglyceride-rich lipoproteins promotes the development of atherosclerosis. This study was designed to test the hypothesis that postprandial lipemia is independently associated with intima-media thickening of the extracranial carotid arteries. METHODS Forty-seven middle-aged, moderately hypercholesterolemic indiv...

BACKGROUND Dyslipidemia is associated with cardiovascular morbidities and mortality. Currently, fasting lipid profile determination is used to monitor treatment response. Recently, postprandial lipemia is of increasing interest because of its atherogenic and thrombogenic potential and also was found to be more predictive for cardiovascular diseases. OBJECTIVES To demonstrate postprandial lipe...

A high-fat meal (HFM) induces an increase in blood lipids (postprandial lipemia; PPL), systemic inflammation, and acute airway inflammation. While acute exercise has been shown to have anti-inflammatory and lipid-lowering effects, it is unknown whether exercise prior to an HFM will translate to reduced airway inflammation post-HFM. Our purpose was to determine the effects of an acute bout of ex...

Triglyceride-rich lipoproteins (TRLs) that are modified during alimentary lipemia and their remnants are indicated to play an important role in the development of atherosclerosis. Although recent studies in transgenic and gene knock-out animal models have shed new light on the function of different apolipoproteins (apos) in the metabolism of TRLs and on their respective role in atherogenesis in...

The aims of the study were to investigate associations of the apolipoprotein (apo) A-IV polymorphisms Thr347Ser and Gln360His with anthropomorphic measurements and fasting and postprandial lipids in subjects participating in the European Atherosclerosis Research Study II (EARS II). The allelic frequencies of Ser347 and His360 were 0.185 and 0.067, respectively, in the sample as a whole. There w...

OBJECTIVE The aim of this study was to compare postprandial lipemia, oxidative stress, antioxidant activity, and insulinemia between a three and six isocaloric high-carbohydrate meal frequency pattern in obese women. DESIGN AND METHODS In a counterbalanced order, eight obese women completed two, 12-h conditions in which they consumed 1,500 calories (14% protein, 21% fat, and 65% carbohydrate)...

We know that upper body obesity is associated with metabolic complications, but we don't know how regional body fat distribution influences postprandial lipemia in obese adults. Thus, this study explored the respective effects of android or gynoid types of obesity and fasting triglyceridemia on postprandial lipid metabolism and especially triglyceride-rich lipoproteins. Twenty-four obese and 6 ...
