An elevated plasma concentration of lipoprotein (a) [Lp(a)] is an independent risk factor for cardiovascular disease. Life style modification and currently available drugs either fail to effectively lower plasma Lp(a) levels or do not result in clinical benefit. However, lipoprotein apheresis is very efficient in decreasing Lp(a) concentrations. A single apheresis session can acutely decrease L...

T he importance of lipid, lipoprotein, and apolipoprotein risk factors in the prediction, prevention, and regression of atherosclerosis is now well established. The role of elevated low density lipoprotein cholestexol (LDL C) in the development of coronary heart disease (CHD) is supported by evidence from numerous epidemiologic studies, clinical trials, and genetic studies.1-3 High density lipo...

OBJECTIVE To assess lipid profile changes in post-menopausal women treated with testosterone gel. METHODS Thirty-six oophorectomized women on estradiol treatment who received transdermal testosterone gel (5mg daily) were enrolled into our study. Cholesterol, triglycerides, high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), very low density-lipoprotein c...

The use of mixtures of well-defined monoclonal antibodies may represent a step forward in the standardization of immunochemical assays. We developed and optimized working conditions for using such a mixture to determine apolipoprotein A-I in human sera by two independent techniques (electroimmuno- and immunonephelometric-assays). Six monoclonal antibodies, each addressed to distinct epitopes lo...

the intake of antioxidants intake has been reported to be inversely associated with the incidence of coronary artery disease. to clarify the possible role of lipophilic antioxidants in prevention of atherosclerosis, we investigated the effects of lycopene on the susceptibility of low-density lipoprotein (ldl) to oxidative modification. in this study, “lycopene” was added to plasma and incubated...

Background: C-reactive protein (CRP) and lipoprotein (a) (Lp[a]) play essential roles in cardiovascular disease incidence. This study aimed to review the association between the intake of conjugated linoleic acid (CLA) in the form of dietary supplement or enriched food with different treatment durations and the levels of Lp(a) and CRP in human studies.Methods: All the articles published i...

Aim: Aim of the study was to find out the serum lipoprotein(a) in healthy and essential hypertensive subjects along with the lipid levels in them to assess that lipoprotein(a) measurement could help in risk stratification in these newly diagnosed essential hypertensive group. Material &Method: Eighty newly diagnosed essential hypertensive patients and seventy healthy subjects were included in t...

Thirty-one consecutive unselected hyperlipidaemic patients were treated daily with 4 g of nicotinic acid for 6 weeks. The concentrations in serum of lipoprotein Lp(a), and the major lipoprotein classes, were determined before and after the treatment. Nicotinic acid significantly reduced the serum levels of Lp(a) in the whole patient group. Linear regression analysis showed a strong negative rel...

BACKGROUND Elevated levels of oxidized phospholipids (OxPLs) on apolipoprotein B-100 particles (OxPL/apoB) are associated with cardiovascular disease and predict new cardiovascular events. Elevated lipoprotein (a) [Lp(a)] levels are a risk factor for cardiovascular disease in whites and also in blacks if they carry small apolipoprotein(a) [apo(a)] isoforms. The relationship of OxPL/apoB levels ...

The precursor-product relationship of very low density (VLDL) and low density lipoproteins (LDL) was studied. VLDL obtained from normal (NTG) and hypertriglyceridemic (HTG) subjects was fractionated by zonal ultracentrifugation and subjected to in vitro lipolysis. The individual subfractions and their isolated lipolysis products, as well as IDL and LDL, were rigorously characterized. A striking...
