introduction: abnormal lipid profile causes maternal mortality and impairs fetal development. this study investigated the effect of ramadan fasting on plasma lipid profile in pregnant women. material and methods: this self-control, cohort study was performed in healthy volunteer fasted pregnant women. serum cholesterol, triglyceride (tg), low density lipoprotein (ldl), high density lipoprotein ...

The importance of low-density lipoprotein (LDL) cholesterol in the development of atherosclerosis has long been recognized, and LDL cholesterol remains the primary target of therapy for the prevention of coronary heart disease. Nevertheless, increasing research attention over the past decade has been devoted to the heterogeneity of LDL particles and the atherogenicity of lipids and lipoproteins...

In addition to low-density lipoproteins, plasma chylomicrons and very-low-density lipoproteins (VLDL) contribute to atherogenesis. When triglyceride-rich particles bind to arterial endothelium and to deendothelialized areas, locally present lipoprotein lipase initiates triglyceride hydrolysis and decreases the size of the adhering particles. Additional changes in composition are brought about b...

Adipose tissue lipoprotein lipase (LPL) is the enzyme responsible for hydrolysis of circulating lipoprotein triacylglycerol (TAG). Successive passages of very-low-density lipoprotein (VLDL) through adipose tissue are thought to produce progressive delipidation of the particles, with the eventual formation of intermediate-density lipoprotein (IDL) and low-density lipoprotein (LDL) [ 1 I . The hy...

A system was developed to measure the mass flow of granular fertilizer material in aerial spreader ducts. The flow process was regarded as the sequential passage of clusters containing multiple particles with varying diameters. An optical sensor was used to measure the cluster lengths on the fly. In a low–density flow regime, the diameter of each particle could be measured individually (this is...

A crude pea (Pisum sativum L. var. Homesteader) mitochrondrial preparation was divided into two equal parts. One part was layered on a Dextran-40 step gradient, and the other on a sucrose step gradient, and they were centrifuged to obtain different bands of particles. The densities at which the particles banded and the mitochondrial respiratory activities of the particles were determined. Dextr...

Mixing of granular solids is invariably accompanied by segregation, however, the fundamentals of the process are not well understood. We analyze density and size segregation in a chute flow of cohesionless spherical particles by means of computations and theory based on the transport equations for a mixture of nearly elastic particles. Computations for elastic particles (Monte Carlo simulations...

the non-enzymatic glycation of low density lipoprotein (ldl) is a naturally occurring chemical modification of apolipoprotein b as a result of condensation between lysine residues and glucose. glycated ldl is poorly recognized by ldl receptors and initiates different processes that can be considered proatherogenic. thus, ldl glycation may contribute in the increased atherosclerotic risk of pati...

objective(s):resveratrol (res) is a polyphenol compound that has been shown a promising cardioprotective effect. however, some reports have yielded conflicting findings. herein, we investigated the anti-atherosclerotic effects of res in apolipoprotein e (apo e)-deficient mice on a high cholesterol diet. materials and methods: firstly, atherosclerosis was induced by feeding a high cholesterol di...
