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...

This study was conducted to evaluate the antimicrobial and antioxidant activities of the hexane and methanol extracts of the aboveground parts and roots of some Astragalus species grown in the vicinity of Erzurum, located in the eastern Anatolia, Turkey. The methanol extract, which was obtained from the aboveground parts of Astragalus species, exhibited mild free radical scavenging activity pro...

Oils and fats are substances that are important nutritionally and have important role and impact on human health. Energy consumption and preservation in respect of food industry and the increase in the world population and search for new sources of oils and fats to full fill the need of the society particulary the nutritional requirements have introduced this research topic. Therefore aim of th...

Human or rat microsomal 5 alpha-reductase activity, as measured by enzymic conversion of testosterone into 5 alpha-dihydrotestosterone or by binding of a competitive inhibitor, [3H]17 beta-NN-diethulcarbamoyl-4-methyl-4-aza-5 alpha-androstan-3-one ([3H]4-MA) to the reductase, is inhibited by low concentrations (less than 10 microM) of certain polyunsaturated fatty acids. The relative inhibitory...

background & aim: purslane (portulaca oleracea l.), belongs to the portulacaceace family, grows in many parts of iran. results of previous studies were indicated purslane is a rich source of essential fatty acids of omega-3 and omega-6.  portulaca oleracea is a widespread weed, being the eighth common plants of the world. the aim of current study was to compare the essential fatty acids com...

Cellular damage caused by reactive oxygen species has been implicated in several diseases, thus establishing a significant role for antioxidants in maintaining human health. Acetone, methanol, and hot water extracts of Pleurotus citrinopileatus were evaluated for their antioxidant activities against β-carotene-linoleic acid and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals, reducing power, ferr...

Pleurotus cornucopiae has been widely used in nutritional and medicinal purposes. This study was initiated to screen the antioxidant activities, tyrosinase inhibitory effects on the fruiting bodies of P. cornucopiae extracted with acetone, methanol and hot water. The antioxidant activities were performed on β-carotene-linoleic acid, reducing power, DPPH, ferrous ions chelating abilities, and xa...
