background: stearic acid is known as a potent anti-inflammatory lipid. this fatty acid has profound and diverse effects on liver metabolism. the aim of this study was to investigate the effect of stearic acid on markers of hepatocyte transplantation in rats with acetaminophen (apap)-induced liver damage. methods: wistar rats were randomly assigned to 10-day treatment. stearic acid was administe...

Background and Objective: An everted intestinal sac (EGS) technique has been used to extensively estimate the transport and intestinal absorption in rats. Therefore, a number of factors such as pH and the nature of solvent may play an important role in fatty acid uptake by entrocytes. There are reports indicating that fatty acid transport is affected by many biochemical parameters including tra...

serum fatty acids on 30 healthy lranian women were detemined by a gas chromatographic method. oleic and stearic acids were used as standards. the mean values were myristic acid 5. 7% , palmitic acid 43% , palmitoleic acid 5.3% , stearic acid 8% , oleic acid 21. 3% and linleic acid 16.4% of total fatty acid serum contents.

Stearic acid nanoparticles were prepared in this study by melt-homogenization to investigate the possibility of them as a new kind of drug carrier system. Some physicochemical properties of stearic acid nanoparticles were studied and morphology examined by transmission electron microscope. Cyclosporin A as a model drug was then encapsulated into stearic acid nanoparticles. Following the establi...

اهمیت مطالعه در خصوص گیاهان دارویی از آنجا حاصل می شود که، یک و یا بخش هایی از این گیاهان حاوی مواد ارزشمند دارویی، غذایی و بهداشتی است. سنتز هر یک از این مواد موثره، فرآیندی طولانی و هزینه بر است. در این تحقیق، روغن کنجد با استفاده از امواج التراسونیک استخراج و سپس با gc/ms شناسایی شد. استفاده از این امواج در استخراج ترکیبات مختلف از بافت های گیاهی راندمان عمل و سرعت فرآیند استخراج را افزایش...

Saturated fatty acids (SFAs), significant components of both enteral/parenteral nutritional formulations (including diet), are linked to cardiovascular disease complications, such as atherosclerosis. We investigated whether oleic acid (C18:1n-9) reduces the growth inhibitory and pro-inflammatory effects of the stearic acid (C18:0) in human aortic endothelial cells (HAEC). Stearic acid induced g...

Stearic acid is a long-chain saturated fatty acid. However, in contrast with other saturated fatty acids, stearic acid apparently does not raise serum cholesterol concentrations. Studies carried out three decades ago provided strong suggestive evidence that this was the case. More recent investigations that specifically compared stearic acid with other fatty acids in human studies have confirme...

Stearic acid (C18:0) is a long chain dietary saturated fatty acid that has been shown to reduce metastatic tumor burden. Based on preliminary observations and the growing evidence that visceral fat is related to metastasis and decreased survival, we hypothesized that dietary stearic acid may reduce visceral fat. Athymic nude mice, which are used in models of human breast cancer metastasis, were...

Unlike other saturated fatty acids, dietary stearic acid does not appear to raise plasma cholesterol. The reason for this remains to be established, although it appears that it must be related to inherent differences in the metabolism of the fatty acid. In the present study, we have looked at the metabolism of palmitic acid and stearic acid, in comparison with oleic acid, by cultured hamster he...
