Diets high in polyunsaturated fatty acids may protect against duodenal ulcer, possibly through inhibiting the growth of Helicobacter pylori. This hypothesis was tested in vitro by incubating H pylori microaerophilically with a range of polyunsaturated fatty acids. omega-3 Linolenic acid significantly, but reversibly, inhibited growth at 1.8, 2.5, and 5 x 10(-4) M (p < 0.01), while concentration...

Deficiency of omega 3 long-chain polyunsaturated fatty acids (LCPUFAs) in vertebrates produces subtle adverse effects on visual and neural function. Preterm infants 1) are deprived of vital intrauterine fat accretion during late pregnancy, 2) must rely solely on formula for fatty acid supplies if not breastfed, and 3) may have limited postnatal desaturase activity. In a study to evaluate the ne...

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 f...

The oxidation rates of lauric, myristic, palmitic, stearic, oleic, alpha-linolenic, linoleic, kappa-linolenic, dihomo-gamma-linolenic and arachidonic acids were studied by use of a radioisotope tracer technique in weanling rats at rest in a metabolism chamber over 24 h. Of the saturated fatty acids, lauric acid (12:0) was the most efficient energy substrate: the longer the chain length of the s...

in order to study the effects of artichoke leaf powder on the quality parameters of thigh and breast meat and the fatty acids profile of breast meat, 240 day-old japanese quails were used. the brids were assigned to 4 treatments including basal diet (control), basal diet supplemented with levels of 15 and 30 g/kg artichoke powder and 300 mg/kg vitamin e with 4 replicates for each treatment in a...

Squids belong to the cephalopod family, which composes more than 5% of the total annual fishing volume of southern Iran as by- products; however, these do not have significant usage in Iran. This product was studied to extract the high-value products, i.e. marine oils rich in unsaturated multiple-band fatty acids from 50kg squid (Loligo loligo) obtained from Chabahar fishing port and transferre...

omega-3 fatty acids (fas) have been shown to prevent cardiovascular disease. the most commonly used omega-3 fatty acids like eicosapentaenoic acid (epa) and docosahexaenoic acid (dha) are highly vulnerable to oxidation and therefore, have short shelf life. recent advances in nanoliposomes provided a biocompatible system for stabilizing omega-3 fas. several methods could be implemented to prepar...

All fats, including saturated fatty acids, have important roles in the body. However, the most important fats are those that the body cannot make and thus must come from the food we eat. These essential fatty acids (EFAs) are based on linoleic acid (omega-6 group) and alpha-linolenic acid (omega-3 group). We need both groups of essential fatty acids to survive. For various reasons EFA deficienc...
