Nine cynomolgus monkeys were rotated randomly through four dietary treatments with each treatment lasting 6 weeks. A wash-out period of 4 weeks was maintained between each dietary rotation. The animals were fed diets containing 32% energy fat derived from palm olein (POL), lauric-myristic-rich oil blend (LM), American Heart Association (AHA) rich oil blend and hydrogenated soybean oil blend (tr...

The objective of the study was to assess the association between plasma levels of lipoprotein(a) [Lp(a)] and the presence of angiographically defined coronary artery disease (aCAD). Patients (346 men and 184 women) undergoing selective coronary angiography (SCA) were classified into groups with positive [aCAD(+)] and negative [aCAD(-)] findings and their age, body mass index (BMI), waist circum...

Objective. To investigate the association between serum lipoprotein ratios and insulin resistance in women with polycystic ovarian syndrome (PCOS). Methods. 105 PCOS patients and 109 controls were randomly enrolled in the study. Serum levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol (E2), total testosterone (T), fasting glucose (FBG), fasting insulin (FINS), ser...

Diabetes mellitus is a common endocrine disorder. Anti-diabetic agents from natural and synthetic sources are available for the treatment of this disease. Berberis integerrima is a medicinal shrub used in conventional therapy for a number of diseases. The aim of the present study was to investigate the effects of aqueous extract of Berberis integerrima root (AEBI) on some physiological paramete...

We studied the heterogeneity of high-density lipoproteins (HDL) in plasma of 110 subjects, using three different methods: (a) gradient gel electrophoresis (GGE); (b) electroimmunoassay, to measure the concentration of lipoprotein particles containing apoprotein (apo) AI but no apo-AII (LP AI); and (c) cholesterol esterification rate (FERHDL) in very-low- and low-density lipoprotein-depleted pla...

Changes of lipoprotein secretion and composition in response to CCl4 treatment were studied in monolayer cultures of rat primary hepatocytes. (1) CCl4 decreased secretion of very low density lipoproteins (VLDL) by about 85%, while high density lipoprotein (HDL) secretion was less affected (about 40%). The effect was concentration-dependent. (2) CCl4 significantly inhibited secretion of VLDL- an...

Testosterone administration to men is known to decrease high-density lipoprotein cholesterol (HDL-C) and the subclasses HDL(2) and HDL(3). It also might increase the number of small, dense, low-density lipoprotein cholesterol (LDL-C) particles in hypogonadal men. The decrease in HDL-C and in LDL-C size is potentially mediated by hepatic lipase activity, which hydrolyzes lipoprotein phospholipid...

We assessed lipid and lipoprotein levels in 100 women taking low-dose COCs and a control group of 100 non-users attending the family planning centre Basra Maternity and Child Hospital, Iraq. Venous blood was collected after 12-14 hours fasting, and serum triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and very ...

OBJECTIVE Plasma levels of high-density lipoprotein cholesterol (HDL-C) are strongly inversely associated with coronary artery disease (CAD), and high HDL-C is generally associated with reduced risk of CAD. Extremely high HDL-C with CAD is an unusual phenotype, and we hypothesized that the HDL in such individuals may have an altered composition and reduced function when compared with controls w...
