N3 FA promote beneficial effects on cardiovascular diseases, but they are highly susceptible to oxidation, which leads to the formation of potentially toxic secondary products. In this study, the antioxidant capacity of natural compounds (sinapic acid and rutin) was evaluated using an accelerated model to oxidize the oils. Five inducers (Temperature, Fe(2+) , AAPH, Ascorbyl palmitate and AMVN) were combined in a factorial design to accelerate the oxidation of three oils (flaxseed, echium and fish) containing different sources of n3 FA...

Context • Psychoneuroimmunology is the interdisciplinary study that links behavioral health with the neuroendocrinal system and investigates that link's bidirectional impact on the human immune system. Mechanistic studies have shown how omega-3 polyunsaturated fatty acids (PUFAs), like those found in fish oil, can modulate key pathways involved in inflammation, sympathetic activity, oxidative stress, transcription factors, and inflammatory cytokine production. Objective • The research team intended to investigate the effects that PUFAs have on the brain and the immune system, including the effects of proinflammatory cytokines and oxidative stress, and their therapeutic benefits in major depressive disorder (MDD) and bipolar disorder, either as an alternative monotherapy or a complementary adjunct treatment...

Dietary consumption of ω-3 polyunsaturated fatty acids (PUFAs), present in fish oils, is known to improve the vascular response, but their molecular targets remain largely unknown. Activation of the TRPV4 channel has been implicated in endothelium-dependent vasorelaxation. Here, we studied the contribution of ω-3 PUFAs to TRPV4 function by precisely manipulating the fatty acid content in Caenorhabditis elegans. By genetically depriving the worms of PUFAs, we determined that the metabolism of ω-3 fatty acids is required for TRPV4 activity...

The aged population is among the highest at risk for ischemic stroke, yet most stroke patients of advanced ages (>80 years) are excluded from access to thrombolytic treatment by tissue plasminogen activator, the only FDA approved pharmacological therapy for stroke victims. Omega-3 polyunsaturated fatty acids (n-3 PUFAs) robustly alleviate ischemic brain injury in young adult rodents, but have not yet been studied in aged animals. This study investigated whether chronic dietary supplementation of n-3 PUFAs protects aging brain against cerebral ischemia and improves long-term neurological outcomes...

INTRODUCTION: Preterm birth accounts for more than 85% of all perinatal complications and deaths. Seventy-five per cent of early preterm births (EPTBs) occur spontaneously and without identifiable risk factors. The need for a broadly applicable, effective strategy for primary prevention is paramount. Secondary outcomes from the docosahexaenoic acid (DHA) to Optimise Mother Infant Outcome trial showed that maternal supplementation until delivery with omega-3 (ω-3) long chain polyunsaturated fatty acid (LCPUFA), predominantly as DHA, resulted in a 50% reduction in the incidence of EPTB and an increase in the incidence of post-term induction or post-term prelabour caesarean section due to extended gestation...

BACKGROUND: Increased consumption of omega-3 (ω-3) fatty acids found in cold-water fish and fish oil has been reported to protect against obesity. A potential mechanism may be through reduction in adipocyte differentiation. Stearidonic acid (SDA), a plant-based ω-3 fatty acid, has been targeted as a potential surrogate for fish-based fatty acids; however, its role in adipocyte differentiation is unknown. This study was designed to evaluate the effects of SDA on adipocyte differentiation in 3T3-L1 cells...

Diabetes-related complications, including cardiovascular disease, retinopathy, nephropathy, and neuropathy, are a significant cause of increased morbidity and mortality among people with diabetes. Previous studies have confirmed that hyperglycemia has pro-oxidative and proinflammatory properties which cause diabetic complications. We hypothesized that supplementation of fish oil emulsion (FOE), rich in omega-3 polyunsaturated fatty acids, to diabetic patients might reduce hyperglycemia-induced pathological changes due to specific properties of FOE...

Unsaturated long-chain fatty acids have been suggested to be beneficial in the context of cardiovascular disorders based in epidemiologic studies conducted in Greenland and Mediterranean. DHA and EPA are omega-3 polyunsaturated fatty acids that are plentiful in fish oil, and oleic acid is an omega-9 monounsaturated fatty acid, rich in olive oil. Dietary intake of these unsaturated long-chain fatty acids have been associated with insulin sensitivity and weight loss, which contrasts with the impairment of insulin sensitivity and weight gain associated with high intakes of saturated long-chain fatty acids...

Omega-3 polyunsaturated fatty acid (ω-3 PUFA)-rich fish oil supplementation has protective effects on heart ischemic injury. Left ventricular (LV) ischemia was induced in rats by permanent ligation of the left coronary artery. Saline, fish oil or soybean oil was administered daily by gavage (3 g kg(-1) b.w.) for 20 days before inducing ischemia. Outcomes were assessed 24 hours after left coronary artery ligation. Pretreatment with fish oil decreased the ω-6/ω-3 fatty acid ratio in the LV. Reduction in infarct size and in the intensity of ventricular systolic dysfunction was found in the fish oil group as compared with the saline or soybean oil groups through echocardiographic evaluation...

Evidence from (31)P magnetic resonance spectroscopy ((31)P MRS) studies suggest that different psychiatric disorders, which typically emerge during adolescence and young adulthood, are associated with abnormalities in mitochondrial bioenergetics and membrane phospholipid metabolism. These disorders are also associated with deficits in omega-3 polyunsaturated fatty acids (n-3 PUFA), including docosahexaenoic acid (DHA) which accumulates in mitochondrial and synaptic membranes. The present study investigated the effects of dietary-induced alterations in brain DHA accrual during adolescence on phospholipid metabolism and bioenergetics in the adult rat brain using (31)P MRS...
