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...

Heme detoxification through crystallization into hemozoin has been suggested as a good target for the development of screening assays for new antimalarials. However, comparisons among the data obtained from different experiments are difficult, and the IC(50) values (the concentrations of drug that are required to inhibit 50% of hemozoin formation) for the same drug vary widely. We studied the e...

Objectives: Potato (Solanum tuberosum L.), as a whole food, contains high levels of vitamins and important antioxidants including phenolic acids, carotenoids and flavonoids. The objective of this study was to determine the total phenolic content and antioxidant activities of three common potatoes (Solanum tuberosum) cultivars in Iran i.e., Savalan, Agria and Sante. Materials and Methods: Pheno...

To explore the antioxidant potential of hen egg white lysozyme N-acetylmuramide Glycan hydrolase in full fat Mozzarella cheese, an experiment was conducted where control sample brined without addition lysozyme; while four samples were along with 0.02%;w/v (T1), 0.04%;w/v (T2), 0.06%;w/v (T3) and 0.08%;w/v (T4) lysozyme. The cheese measured through several methods, including 2, 2-azino-bis (3-et...

antioxidants are vital substances which possess the ability to protect the body from damage caused by free radical induced oxidative stress. a variety of free radical scavenging antioxidants exist within the body which many of them are derived from dietary sources like fruits, vegetables and teas. in this study the antioxidant activity and radical scavenging activity of methanolic extracts of s...

agaricus bisporus and agaricus bitorquis are among most favorite mushrooms of the world. mineral contents, proximate composition and fatty acid profile of these mushrooms were determined for evaluation of their dietary value. na, k and li contents were high, while cr, cu, pb, co, zn, mn and ni concentrations were low in both agaricus bisporus and agaricus bitorquis. proximate analysis showed th...
