Turnover of 125I-low density lipoprotein (LDL) and of 131I-high density lipoprotein (HDL) was determined before and after end-to-side portacaval shunt in eight swine. LDL (d 1.019-1.063) and HDL (d.1.09-1.21) were isolated by ultracentrifugation and iodinated by the iodine monochloride technique. Immediately postoperatively there was no consistent change in the fractional catabolic rate (FCR) o...

OBJECTIVE Progression of carotid intima-media thickness (CIMT) is a surrogate indicator for the early stages of atherosclerosis. METHODS The study investigated relationships between baseline lipoprotein cholesterol, triglyceride (TG), and apolipoprotein (Apo) B levels assessed with density gradient ultracentrifugation (DGU) and progression of posterior wall common CIMT in men (45-75 years of ...

To determine if plasma lipoproteins interact and therefore possibly regulate intestinal lipoprotein metabolism, we investigated the binding, internalization, and degradation of 125I-labeled low density lipoprotein (LDL) and high density lipoprotein (HDL) by enzyme-dispersed rat intestinal mucosal cells. Both human and rat LDL and HDL were bound, internalized, and degraded in a concentration-dep...

The prevalence of vascular disease among 154 diabetic patients was analysed in relation to the serum concentrations of individual lipoproteins. Overal the presence of vascular disease (59 cases) was positively associated with serum cholesterol and low-density-lipoprotein cholesterol but negatively associated with high-density-lipoprotein (HDL) cholesterol. The negative relation between HDL and ...

Decreases in high-density lipoprotein cholesterol (HDL-C) levels are associated with an increased risk of coronary artery disease (CAD), whereas increased HDL-C levels are related to a decreased risk of CAD and myocardial infarction. Although HDL prevents the oxidation of low-density lipoprotein under normal conditions, it triggers a structural change, inhibiting antiarteriosclerotic and anti-i...

A systematic review and meta-analysis of Mendelian randomization studies using Medline, Cumulative Index to Nursing Allied Health Literature Complete, Scopus databases. Sixteen involving 34,050 patients with an abdominal aortic aneurysm (AAA) 2,205,894 controls were included. Meta-analyses suggested that a 1 standard deviation increase in high-density lipoprotein cholesterol (HDL-C) significant...

Herein we report a sensor array based on quartz crystal microbalance (QCM) to simultaneously detect two biomarkers, namely low-density lipoprotein (LDL), and high-density lipoprotein (HDL). Selective recognition takes place through molecularly imprinted polymers (MIP) with both MIPs and corresponding non-imprinted polymer (NIP) as reference electrode. Sensor array performs highly appreciably in...

to evaluate the effectiveness of conjugated estrogen (premarin) and progesterone in twenty-one postmenopausal women who had been menopause one year, we tested during a 6-month period the serum lipoprotein levels in subjects who offered by premarin in dosage of 0.625 milligram for days 1 to 25 and oral medroxy progestrone acetste for days 15 to 25 of a 30-day cycle. twenty-one subjects completed...

OBJECTIVE To determine whether obesity and insulin resistance associate with changes in the protein content of high-density lipoprotein (HDL) in 2 different groups of men by using targeted proteomics. METHODS AND RESULTS Insulin resistance and obesity are hallmarks of type 2 diabetes mellitus and the metabolic syndrome, which confer an increased risk of cardiovascular disease. Recent studies ...
