CONTEXT Next to Alzheimer disease, vascular dementia is the second most common form of dementia in the elderly, yet few specific risk factors have been identified. OBJECTIVE To investigate the relationship of plasma lipids and lipoproteins to dementia with stroke. DESIGN AND SETTING Prospective longitudinal community-based study over a 7-year period (1991-1998). PARTICIPANTS A total of 11...

We identified the first insertion mutation that specifies an apolipoprotein (apo)B truncation, apoB-70.5, in a father and son with hypobetalipoproteinemia (total and low-density lipoprotein [LDL] cholesterol < 5th percentile, plasma apoB levels approximately one third of normal). The mutation is due to insertion of an adenine (A) into a 7-A repeat between cDNA position 9754 and 9760 of the apoB...

The term plasma lipid profile considers measurement of certain components of plasma including total cholesterol (TCh), high density lipoprotein cholesterol (HDL-Ch), triglycerides (Tg), low density blipoprotein cholesterol (LDL-Ch) and very low density lipoprotein cholesterol (VLDL-Ch). TCh consists of all the cholesterol present in different lipoproteins like high density lipoprotein (HDL), lo...

UNLABELLED The aim of our study was to investigate the effects of atorvastatin on serum levels of total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), apolipoprotein A1 (apoA1), apolipoprotein B (apoB) and lipoprotein (a) in patients with primary hyperlipidemia and established coronary heart disease. MATERIAL AND METHODS A group of 96 patients (pts), of both ...

Plasma low density lipoprotein (LDL) comprises multiple discrete subclasses differing in size, density, and chemical composition. A common, heritable phenotype characterized by the predominance of small, dense LDL particles (LDL subclass phenotype B) is associated with relatively increased concentrations of plasma triglycerides, reduced levels of high density lipoprotein, and increased risk of ...

Scavenger receptor BI (SR-BI) is a multiligand cell-surface receptor that plays a central role in high density lipoprotein homeostasis in rodents. To investigate a role for SR-BI in atherosclerosis, mice with attenuated SR-BI expression were crossed with low density lipoprotein (LDL) receptor-deficient mice. Compound-homozygous mutants showed increased plasma cholesterol, surprisingly due prima...

Increased serum level of low-density lipoprotein is associated with coronary artery disease. There are, however, no reports on whether the same is true in hypertensive retinopathy. A cross-sectional comparative study was carried out to evaluate the serum level status of low-density lipoprotein in hypertensive retinopathy, including 30 randomly selected subjects with hypertensive retinopathy; ag...

Despite the well-established observation that substitution of saturated fats for carbohydrates or unsaturated fats increases low-density lipoprotein (LDL) cholesterol in humans and animal models, the relationship of saturated fat intake to risk for atherosclerotic cardiovascular disease in humans remains controversial. A critical question is what macronutrient should be used to replace saturate...

The effect of angiotensin converting enzyme inhibitor, temocapril hydrochloride on the serum lipoproteins, and especially on the size of low density lipoproteins (LDL) of hypertensive diabetic patients, were studied. Temocapril hydrochloride (5 mg/day) was administered to 32 hypertensive type 2 diabetes patients for 16 weeks. During treatment, systolic and diastolic blood pressures decreased si...
