Using 2-16% gradient gel electrophoresis, we examined low density lipoprotein (LDL) particle size in relation to plasma lipoproteins in 1,168 women and 1,172 men from the Framingham Offspring Study. In addition, we studied the effect of dietary intake on LDL size in a subset of the population. Seven LDL size peaks were identified, with the largest, LDL 1, being found in the density range 1.019-...

Familial Hypercholesterolemia (FH) is a genetic disorder, an expression of defect in the gene that responsible for production LDL-C receptor. The current study was designed to determine FH patients city Sulaymaniyah both sexes. included 213 samples, number males 99 and females 114, sexes ranged from (30-79) years.The results cholesterol, triglyceride, high density lipoprotein (HDL-C), low-densi...

According to the low-density-lipoprotein (LDL) receptor hypothesis, development of atherosclerosis is caused by a high concentration of LDL-cholesterol in the blood, and lowering LDLcholesterol reverses, or at least retards, atherosclerosis, thus preventing cardiovascular disease. As a scientific hypothesis, it is open to falsification: if the concentration of LDL-cholesterol or total cholester...

The influence of a high-cholesterol diet on the atherogenicity of the low-density lipoprotein (LDL) particle was examined by measuring LDL peak diameter and composition, LDL susceptibility to oxidation, and the distribution of cholesterol between LDL subclasses. The crossover intervention randomly assigned 27 premenopausal women and 25 men (18 to 50 years) to an egg (640 mg/d additional dietary...

We have conducted a dietary trial in 54 men and 51 women with a wide range of fasting cholesterol values to examine the use of low density lipoprotein (LDL) particle size to predict the lipoprotein response to dietary fat and cholesterol. After a 2-week low fat period, subjects were given two liquid supplements in addition to their low fat diet for 3 weeks each, one containing 31-40 g of fat an...

These studies were undertaken to examine the effect of aging on low density lipoprotein (LDL) metabolism in the male hamster. When the hamsters were maintained on a low-cholesterol, low-triglyceride diet, rates of LDL transport in the various tissues of the body and plasma LDL-cholesterol concentrations remained constant over the entire life span (1-24 months) of the hamster. In contrast, rates...

Cultured human smooth muscle and adventitial cells were incubated with human serum and low density lipoprotein (LDL) to study the uptake and accumulation of cholesterol ester from exogenous LDL. The cellular total cholesterol varied with the amount of LDL cholesterol in the medium. The cholesterol ester content increased 4-fold after 2 hours of incubation. A 6-fold rise occurred by 24 hours and...

Aim: According to studies, the individual cardiovascular disease (CVD) risk is predicted and low density lipoprotein cholesterol (LDL
 cholesterol) sub-group concentration better than LDL cholesterol. High fat intakes are generally considered pose a risk
 on CVD. The purpose of this study analogize pre post diet with LowFat LowCholesterol
 written prescription dyslipidemic sicks ...

OBJECTIVE Evidence favors apolipoprotein B (apoB) over LDL cholesterol as a predictor of cardiovascular events, but data are lacking on coronary artery calcification (CAC), especially in type 2 diabetes, where LDL cholesterol may underestimate atherosclerotic burden. We investigated the hypothesis that apoB is a superior marker of CAC relative to LDL cholesterol. RESEARCH DESIGN AND METHODS W...
