High density lipoprotein (HDL) cholesterol concentrations have been shown to increase with regular endurance exercise and, therefore, can contribute to a lower risk of coronary heart disease in physically active individuals compared with sedentary subjects. Although low HDL cholesterol levels are frequently observed in combination with hypertriglyceridemia, some individuals may be characterized...
هدف از این مطالعه ارزیابی میزان لیپوپروتئین آ در بیماران دیابتی در مقایسه با گروه کنترل بود. همچنین یافتن ارتباط بین کنترل قند خون و چربی های خون با لیپوپروتئین ? در بیماران دیابتی و گروه کنترل. مواد و روش ها: در این مطالعه مورد شاهدی186 فرد 20 تا 70 ساله شامل 100 بیمار دیابت نوع 2 و 24 بیمار دیابت نوع 1 و 62 فرد سالم به عنوان گروه کنترل وارد مطالعه شدند. تمام بیماران دیابتی تحت کنترل قند خو...
مقدمه: با توجه به برخی محدودیتهای استفاده از میزان ldl سرم به عنوان شاخص ارزیابی کننده ی شانس خطر بروز بیماری های کرونر، اخیراً نشان داده شده که آپولیپوپروتئین b بر این شاخص ارجح است. non-hdl-cholestrol که از تفاضل کلسترول تام و hdl سرم به دست می آید، در برگیرنده ی ذرات لیپوپروتئینی آتروژنیک از جمله آپولیپوپروتئین b است و می تواند به عنوان یک شاخص برآورد آپولیپوپروتئین b برای ارزیابی شانس خطر بر...
The ability of high density lipoproteins (HDL) to induce the clearance of cholesteryl esters from cultured cells has been explored. Studies using the J774 mouse macrophage cell line showed that these cells are not stimulated to clear esterified cholesterol upon exposure to HDL. This was observed over a wide range of HDL concentrations (10 to 1000 micrograms/ml HDL protein), and the lack of stim...
RATIONALE High-density lipoprotein (HDL) is a heterogeneous population of particles. Differences in the capacities of HDL subfractions to remove cellular cholesterol may explain variable correlations between HDL-cholesterol and cardiovascular risk and inform future targets for HDL-related therapies. The ATP binding cassette transporter A1 (ABCA1) facilitates cholesterol efflux to lipid-free apo...
The objective of this study was to determine whether high density lipoproteins (HDL) that have been treated with hepatic lipase have an enhanced ability to deliver cholesterol to cells. Human HDL was incubated with rat hepatic lipase, reisolated, and subjected to compositional analysis. Approximately 28% of the HDL phosphatidylcholine was hydrolyzed by the hepatic lipase but no change was detec...
Nauclea latifolia (N. latifolia) and Pteleopsis suberosa (P. suberosa) are two medicinal plants used to treat several pathologies linked oxidative stress. This study aims the effects of ethanolic extracts from those on consequences cholesterolemic overload. Oxidative stress was induced by In vitro antioxidant activity evaluated using DPPH, total phenolic compounds flavonoids assays; while in vi...
Uptake of cholesterol from peripheral cells by nascent small HDL circulating in plasma is necessary to prevent atherosclerosis. This process, termed reverse cholesterol transport, produces larger cholesterol-rich HDL that transfers its cholesterol to the liver facilitating excretion. Most HDL in plasma is cholesterol-rich. We demonstrate that treating plasma with a novel selective delipidation ...
OBJECTIVE Patients with type 2 diabetes mellitus (T2D) have an increased risk of cardiovascular disease, the mechanism of which is incompletely understood. Their high-density lipoprotein (HDL) particles in plasma have been reported to have impaired cholesterol efflux capacity. However, the efflux capacity of HDL from interstitial fluid (IF), the starting point for reverse cholesterol transport,...
