Rat hepatoma (Morris 7777) cells modified with either oleic or linoleic acid exhibited greater susceptibility to normal spleen cell-mediated lysis in a 16-hr 51Cr release assay. At effector:target cell ratios of 300:1, the specific lysis of fatty acid-enriched target cells (cultured for 2 days in fatty acid-supplemented medium) by the normal rat spleen cells was 60% higher than the untreated ta...

iran annually exports considerable quantities of nuts such as almonds, hazelnuts, pista-chios and walnuts. the fatty acid profile of these nut oils as an index of their quality was determined using gas chromatography. results indicated that oleic acid (c18:1) was the major fatty acid in almonds (75.37%), hazelnuts (76.21%) and pistachios (60.49%) fol-lowed by linoleic acid (c18:2), whereas in w...

In vitro antioxidant activity of extracts lotus rhizome with different solvent by gradient extraction was determined. The yield and total phenolic content were 1,1-diphenyl-2-picrylhydrazyl hydrate (DPPH) radical scavenging assay β-carotene-linoleic acid conducted to assess the extracts. Results showed that butanol extract highest. order in as follows: water < petroleum ether chloroform ethyl a...

Both the World Health Organization and the International Obesity Task Force have classified the prevalence of obesity as a global epidemic. The primary causes of obesity are sedentary lifestyles and high-fat diets. Such diets are preferred due to their high palatability. Fats are broken down into free fatty acids, such as linoleic and oleic acids. In order to determine the neural pathway respon...

Background & Aim: Osmotic stress in plants lead to increase free radicals and plants use different mechanisms to scavenge these radicals. So, researchers apply stresses especially drought stress to increase secondary metabolites such as phenolics, and antioxidants. One of the valuable medicinal plants is yarrow (Achillea tenuifolia) which is a perennial plant with different medicinal a...

background: considering the wide consumption of some synthetic antioxidants and their probable negative health effects, in this study, the protective effects of satureja hortensis l. extracts in stabilizing soybean oil against oxidation at different concentrations (200 and 400 ppm) were tested. methods: the aerial parts of s. hortensis l. were collected from isfahan province and extracted with ...
