We have developed an automated method for measuring high-density lipoprotein (HDL)-cholesterol in serum without prior separation, using polyethylene glycol (PEG)-modified enzymes and sulfated alpha-cyclodextrin. When cholesterol esterase and cholesterol oxidase enzymes were modified with PEG, they showed selective catalytic activities towards lipoprotein fractions, with the reactivity increasin...

  Purpose: Ascorbic acid has protective effects against coronary heart disease. These effects are   attributed to its antioxidant properties and its relation to plasma lipids. This study investigated the   effects of supplementing one gram of vitamin C per day on the serum serum lipoproteins of   healthy 18 to 55 years old individuals in Iran.   Materials and Methods: This study was conducted o...

BACKGROUND Low plasma 25-hydroxyvitamin D [25(OH)D] levels are associated with high cardiovascular risk. This may be because that low 25(OH)D levels are associated with high levels of atherogenic lipoproteins, but whether these 2 risk factors are genetically associated is unknown. We tested this hypothesis. METHODS AND RESULTS Using a Mendelian randomization approach, potential genetic associ...

Concentrations of apoprotein A in whole serum, and cholesterol and phospholipids concentrations in the high-density lipoprotein fraction of serum were measured after the precipitation of low-density and very-low-density lipoproteins with sodium phosphotungstate-Mg2+ in 23 patients with liver cirrhosis, 19 patients with extrahepatic biliary obstruction, and 20 healthy control subjects. Patients ...

OBJECTIVE Toremifene and tamoxifen have been used for adjuvant therapy in post-menopausal patients with breast cancer in Japan. Dyslipidemias are common in post-menopausal women. However, limited data are available on the effects of these agents on lipid profiles in Japanese patients. The Japan Toremifene Cooperative Study Group has been conducting a Phase III randomized trial of post-menopausa...

During the period 1971 to 1975, the cholesterol content of lipoprotein density classes were measured in 2415 male and female Framingham Heart Study participants and 4342 of their offspring and offspring spouses who were free of coronary heart disease. In this first of three papers, the univariate and bivariate distributions of high density lipoprotein cholesterol, low density lipoprotein choles...

The plasma appearance of newly synthesized cholesterol in anhepatic laboratory diet-fed rats was 10% of the intact rat. In intact rats this cholesterol was mainly ester in lower density lipoproteins, but for anhepatic rats it was virtually only free in high density lipoprotein. Chylomicron cholesterol ester was removed much more slowly from anhepatic than control plasma and returned primarily a...

BACKGROUND Mycosis fungoides, the most common subtype of cutaneous T-cell lymphoma, is more common in patients aged 45-55. OBJECTIVE Cardiovascular risk factors have been investigated in several skin diseases. However, the relation between cardiovascular diseases and mycosis fungoides remains unclear. Therefore, the aim of this study was to assess cardiovascular risk factors in patients with ...

Background The global prevalence of type 2 diabetes is increasing. Dyslipidaemia is a known complication of diabetes mellitus manifesting frequently as cardiovascular diseases and stoke. Elevation of small, dense low density lipoprotein has been recognised as a component of the atherogenic lipoprotein phenotype associated with cardiovascular complications. We speculate that the elevation of thi...
