Acquired azole resistance in opportunistic fungi causes severe clinical problems in immunosuppressed individuals. This study investigated the molecular mechanisms of azole resistance in clinical isolates of Candida glabrata. Six unmatched strains were obtained from an epidemiological survey of candidiasis in immunocompromised hosts that included azole and amphotericin B susceptible and azole re...

Epidemiological and animal-based investigations have indicated that the development of skin cancer is in part associated with poor dietary practices. Lipid content and subsequently the derived fatty acid composition of the diet are believed to play a major role in the development of tumorigenesis. Omega 3 (omega3) fatty acids, including docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA)...

background and objectives: probiotic bacteria are able to absorb fatty acids present in the culture medium and convert them into intracellular fatty acids, which may affect the physicochemical properties of probiotics. subsequently, changing the composition of cellular fatty acids of probiotics improves the electron acceptance capacity of these microorganisms, and results in an increased adhesi...

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...

this study carried out to determine the differences between oil content and fatty acid compositions of 12 exotic and 6 local safflower genotypes. the experiments were arranged in randomized complete blocks design with three replications in research station of ferdowsi university of mashhad. the results of variance analysis showed that the differences of seed yield, oil content and fatty acid co...

A most effective and less energy demanding method of producing fatty esters, diol esters, by esterifying fatty acids, with neopentyl and ethylenglycol alcohols in the presence of an acidic ion exchange resin catalyst(polyestyrendivinylbenzensulfated) was investigated at elevated temperature. In this process an azeotroping agent, toluene, was used to facilitate continuous removal of water by dis...

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...

Evaluation of four safflower (Carthamus tinctorius L.) genotypes for oil content and fatty acidcomposition showed that oil content varied from 22.16 to 34.39% and the highest seed oilcontent was obtained from Isfahan14 genotype (34.39%, respectively). Among those fatty acidswere detected, linoleic acid (75.81- 77.86%) was the predominant fatty acid followed by oleic(12.57–13.75%), palmitic (6.0...

ba ckground: although some studies have shown positive effects of omega-3 fatty acid supplementation on nutritional status of cancer patients undergoing different treatments, there is no consistency in results. the aim of this study was to examine the effects of omega-3 fatty acid on the nutritional status of gastric cancer patients during the course of chemotherapy. m ethods : in a double-blin...
