There is emerging evidence that Omega-3 polyunsaturated fatty acids (PUFA) supplements can decrease aggression. However, experimental studies with adults from non-specific populations are scarce. We hypothesized that Omega-3 supplements would decrease self-reported aggression among non-clinical participants. In a double-blind randomized trial, two groups of participants (N = 194) aged 18-45 from the general population followed a 6-weeks treatment with 638mg docosahexaenoic acid (DHA) and 772mg eicosapentaenoic acid (EPA) per day or the equivalent quantity of copra oil (placebo)...

Elderly and patients affected by chronic diseases face a high risk of muscle loss and impaired physical function. Omega 3 fatty acids (FA) attenuate inflammation and age-associated muscle loss, prevent systemic insulin resistance and improve plasma lipids, potentially impacting on sarcopenia. This paper aims to review recent randomized clinical studies assessing the effects a chronic omega 3 FA supplementation on inflammatory and metabolic profile during conditions characterized by sarcopenia (aging, insulin resistance, type 2 diabetes, chronic renal failure)...

The regular consumption of long-chain omega-3 polyunsaturated fatty acids (LCO3-PUFAs) results in general health benefits. The intake of LCO3-PUFAs has been reported to contribute to bone metabolism. We aimed to investigate the relationships between dietary intakes of LCO3-PUFAs and bone mineral density (BMD) in Spanish women aged 20-79 years old. A total of 1865 female subjects (20-79 years old) were enrolled, and lumbar (L2, L3, L3 and total spine), hip (femoral neck (FN), femoral trochanter (FT) and Ward's triangle (WT)) bone mineral density (BMD) were measured by dual energy X-ray absorptiometry (DXA)...

OBJECTIVES: The association between circulating biomarkers of red blood cells (RBC) omega-3 polyunsaturated fatty acids (PUFAs) and cerebral white matter hyperintensities (WMH) on the brain MRI remains yet unclear. We investigated the cross-sectional and prospective associations of RBC omega-3 PUFAs with WMH in dementia-free older adults with subjective memory complaints. DESIGN: Participants were 234 older adults with assessments for both PUFA and MRI near to baseline; among them, 79 also had an MRI assessment at 3-year follow-up...

Duchenne muscular dystrophy (DMD) is a progressive and fatal disease, characterized by the absence of dystrophin, muscle degeneration and cardiorespiratory failure. Creatine kinase is the classic marker to screen for DMD. However, other markers are needed to follow disease progression and to evaluate the response to therapy over longer periods. In the present study, we aim to identify interleukins in the plasma of the mdx mice model of DMD that could serve as biomarkers to monitor dystrophy progression, at distinct stages of the disease (1, 3 and 8 months of age)...

BACKGROUND: Although statins reduce cardiovascular events, residual risk remains. Therefore, additional modalities are needed to reduce risk. We evaluated the effect of eicosapentaenoic acid and docosahexaenoic acid in pharmacologic doses added to statin treatment on coronary artery plaque volume. METHODS AND RESULTS: A total of 285 subjects with stable coronary artery disease on statins were randomized to omega-3 ethyl-ester (1.86 g of eicosapentaenoic acid and 1...

Abdominal pain is one of the key symptoms of irritable bowel syndrome (IBS). Studies have indicated an increase in the incidence of IBS in Asia. However, yet the pathophysiology of this disease remains unknown. Women are more likely to develop the condition than men, especially the constipation-predominant type. Essential fatty acid (EFA) malnutrition is one of several theories discussing the mechanism of IBS.The authors hypothesized that significant EFA deficiency may cause abdominal pain in patients with IBS...

BACKGROUND: Regular fish and omega-3 consumption may have several health benefits and are recommended by major dietary guidelines. Yet, their intakes remain remarkably variable both within and across populations, which could partly owe to genetic influences. OBJECTIVE: To identify common genetic variants that influence fish and dietary eicosapentaenoic acid plus docosahexaenoic acid (EPA+DHA) consumption. DESIGN: We conducted genome-wide association (GWA) meta-analysis of fish (n = 86,467) and EPA+DHA (n = 62,265) consumption in 17 cohorts of European descent from the CHARGE (Cohorts for Heart and Aging Research in Genomic Epidemiology) Consortium Nutrition Working Group...

Polyunsaturated fatty acids omega-3 (n-3 PUFA), such as docosahexaenoic acid (DHA), have been shown to prevent, and partially reverse, neurotoxin-induced nigrostriatal denervation in animal models of Parkinson's disease (PD). However, the accumulation of α-synuclein (αSyn) in cerebral tissues is equally important to the pathophysiology. To determine whether DHA intake improves various aspects related to synucleinopathy, ninety male mice overexpressing human αSyn under the Thy-1 promoter (Thy1-αSyn) were fed one of three diets (specially formulated control, low n-3 PUFA or high DHA) and compared to non-transgenic C57/BL6 littermate mice exposed to a control diet...

Classically, polyunsaturated fatty acids (PUFA) were largely thought to be relatively inert structural components of brain, largely important for the formation of cellular membranes. Over the past 10 years, a host of bioactive lipid mediators that are enzymatically derived from arachidonic acid, the main n-6 PUFA, and docosahexaenoic acid, the main n-3 PUFA in the brain, known to regulate peripheral immune function, have been detected in the brain and shown to regulate microglia activation. Recent advances have focused on how PUFA regulate the molecular signaling of microglia, especially in the context of neuroinflammation and behavior...

OBJECTIVES: Elevated total plasma homocysteine is a risk factor for Alzheimer's disease (AD) and there is some evidence that omega-3 polyunsaturated fatty acids (n-3 PUFAs) can modulate the effects of homocysteine-lowering B vitamins on AD related pathologies. Hence we investigated the relationship between total plasma homocysteine and cortical β-amyloid (Aβ) in older adults at risk of dementia. The role of erythrocyte membrane n-3 PUFAs (omega 3 index) on this relationship was also explored...

Coenzyme Q10 (CoQ10) is a vitamin-like oil-soluble molecule that has anti-oxidant and anti-ageing effects. To determine the most optimal CoQ10 delivery vehicle, CoQ10 was solubilised in both water and fish oil, and formulated into hydrogel, oleogel and bigel. Permeability of CoQ10 from each formulation across porcine ear skin was then evaluated. Furthermore, the effects of the omega-3 fatty eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids from fish oil on skin permeation were investigated by means of nuclear magnetic resonance (NMR) and computerised molecular modelling docking experiments...

Utilization of nutrients to improve overall heifer health is of interest because of the importance of replacement heifers to the dairy industry. The objective of our study was to compare the effect of supplementation of dietary n-3 and n-6 fatty acids (FA) on FA concentrations in peripheral blood mononuclear cells (PBMC) of Holstein calves. Twenty-seven Holstein heifer calves (107 ± 2.6 d of age; 142.6 ± 6.5 kg of body weight) from the university research and teaching herd were randomly assigned to a common TMR supplemented with 1 of 3 treatments: Ca salts of flaxseed FA (Virtus Nutrition, Corcoran, CA) containing 35% 18:3 n-3 (N3), Ca salts of soybean FA (Virtus Nutrition) containing 50% 18:2 n-6 (N6), or a 50:50 mix of N3 and N6...
