Our previous studies revealed that offspring from rat dams fed fish oil (at 8% and 18% energy), developed impaired intestinal barriers sensitizing the colon to exacerbated injury later in life. To discern the mechanism, we hypothesized that in utero exposure to fish oil, rich in n-3 polyunsaturated fatty acid (PUFA), caused abnormal intestinal reparative responses to mucosal injury through diff...

Psychological stress has been shown to modulate immune functions. In this study, we investigated the effect of dietary oils (olive oil, soybean oil, and fish oil) on the social isolation stress-induced modulation of lymphocyte immunological activities in mice. In olive oil-fed, but not soybean oil- or fish oil-fed, mice, a 2-week isolation stress decreased the lymphocyte proliferative response,...

BACKGROUND Effects of fish oil on systematic inflammation in chronic heart failure remain unclear. In this meta-analysis, we aimed to evaluate the influence of fish oil supplementation on circulating levels of inflammatory markers in patients with chronic heart failure. METHODS Human randomized controlled trials, which compared the effects of fish oil supplementation with placebo in patients ...

OBJECTIVES To determine whether high-dose fish oil is superior to low-dose supplementation for symptomatic and structural outcomes in knee osteoarthritis (OA). METHODS A randomised, double-blind, multicentre trial enrolled 202 patients with knee OA and regular knee pain. They were randomised 1:1 to high-dose fish oil (4.5 g omega-3 fatty acids) 15 mL/day or (2) low-dose fish oil (blend of fis...

Fish oil rich in n-3 polyunsaturated fatty acids has been shown to reduce the risk of cardiovascular diseases partly by reduction of blood triglyceride concentration. This favorable effect mainly results from the combined effects of inhibition of lipogenesis by decrease of SREBP-1 and stimulation of fatty acid oxidation by activation of peroxisome proliferator-activated receptor-alpha (PPARalph...

Vegetable oils (VO) are possible substitutes for fish oil in aquafeeds but their use is limited by their lack of omega-3 (n-3) long-chain polyunsaturated fatty acids (LC-PUFA). However, oilseed crops can be modified to produce n-3 LC-PUFA such as eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids, representing a potential option to fill the gap between supply and demand of these important n...

background: in recent years, many studies have been conducted on finding a suitable replacement for fish meal to supply the needs of aquaculture feed industry. objectives: the present study was performed to examine the effect of replacing fish meal and fish oil with plant sources on bacterial counts in intestinal contents and mucus and bacterial composition in beluga sturgeon. methods: beluga s...

During atherogenesis, a pathological accumulation of lipids occurs within aortic intimal macrophages through uptake of oxidised low-density lipoprotein (LDL) via scavenger receptors. Here we investigate whether some of the anti-atherosclerotic effects ascribed to dietary fish oil are mediated through effects on macrophage intercellular adhesion molecule 1 (ICAM-1) and scavenger receptor express...

The protective effect of the (n-3) fatty acids in menhaden fish oil on acute cerebral ischemia was investigated in cats. Cerebral ischemia was produced by ligation of the left middle cerebral artery of cats fed either a basal diet of feline cat chow or the basal diet supplemented with 8% of the calories as menhaden oil for 18-24 days. Fatty acids esters of 20:5 (n-3) were increased and the 18:2...

Abstract—In this study, lipase production has been investigated using submerge fermentation by Aspergillus niger in Kilka fish oil as main substrate. The Taguchi method with an L9 orthogonal array design was used to investigate the effect of parameters and their levels on lipase productivity. The optimum conditions for Kilka fish oil concentration, incubation temperature and pH were obtained 3 ...
