The ratio of omega-3 to omega-6 fatty acids, especially the long-chain eicosapentaenoic acid (EPA) + docosahexaenoic acid (DHA) to arachidonic acid (AA) ratio, is inversely associated with breast cancer risk. We measured the association between cytologic atypia, a biomarker for short-term risk of breast cancer development, and omega-3 and omega-6 fatty acid intake and levels in blood and breast...
OBJECTIVE To review systematically the evidence for an effect of long chain and shorter chain omega 3 fatty acids on total mortality, cardiovascular events, and cancer. DATA SOURCES Electronic databases searched to February 2002; authors contacted and bibliographies of randomised controlled trials (RCTs) checked to locate studies. REVIEW METHODS Review of RCTs of omega 3 intake for (3) 6 mo...
BACKGROUND Omega-3 fatty acids are known to prevent cardiac death. However, previous observational studies have suggested that omega-3 fatty acids are associated with cancer risk in adults. We conducted a meta-analysis based on randomized controlled trials to evaluate the effect of omega-3 fatty acids on the risk of cancer incidence, nonvascular death, and total mortality. METHODS In February...
Background and Objectives: There are conflicting data on the effects of different types of fat on aortic atherosclerosis. This study used Wister rats to compare the atherogenic effects of a standard diet with a diet containing fish oil and another diet containing mixed oils (typical of the current consumption pattern in Iran). Methods: Thirty female Wistar rats were randomly assigned to three ...
The fatty acid composition of the intramuscular lipids of cattle, pigs and birds were determined relative to breed and feeding regime. The cattle included Yellow Cattle, Hereford and Japanese Black; pigs included Wild-boar, Touyuens and Yorkshires; the birds were Wild-birds, Jungle-fowl and broilers. The pen fed animals such as Japanese Black cattle and Yorkshire pigs had a higher amounts of ol...

لوله ورتکس یک وسیله ساده مکانیکی است که فاقد قسمت های متحرک بوده ویکی از تجهیزات مورد استفاده در سیستم تبرید می باشد، که در آن یک سیال پرفشار از طریق نازل های ورودی وارد لوله ورتکس شده و به دو جریان با دمای کمتر، و بیشتر از دمای ورودی منشعب می شودبدین صورت می توان دماهای تا 40- درجه سلسیوس را ایجاد کرد.اگرچه با وجود اینکه تاکنون مطالعات تجربی زیادی بر روی عملکرد لوله ورتکس صورت گرفته است اما هم...
Omega-3 fatty acids are important for several neuronal and cognitive functions. Altered omega-3 fatty acid status has been implicated in reduced resistance to stress and mood disorders. We therefore evaluated the effects of repeated restraint stress (6 h/day for 21 days) on adult rats fed omega-3 deficient, control or omega-3 enriched diets from conception. We measured body weight, plasma corti...
background and purpose: recent reports suggest that increased homocysteine is a risk factor for heart disease. on the other hand, regular exercise and supplementation of omega-3 fatty acids have been effective in reducing these diseases. the purpose of this study was to evaluate the interaction effect of 8 weeks of aerobic training and omega-3 fatty acid supplementation on plasma homocysteine c...
