Arachidonic Acid, but Not Omega-3 Index, Relates to the Prevalence and Progression of Abdominal Aortic Aneurysm in a Population-Based Study of Danish Men.

Animal models support dietary omega-3 fatty acids protection against abdominal aortic aneurysm (AAA), but clinical data are scarce. The sum of red blood cell proportions of the omega-3 eicosapentaenoic and docosahexaenoic acids, known as omega-3 index, is a valid surrogate for long-term omega-3 intake. We investigated the association between the omega-3 index and the prevalence and progression of AAA. We also investigated associations between AAA and arachidonic acid, an omega-6 fatty acid that is a substra...

Whole blood omega-3 fatty acid concentrations are inversely associated with blood pressure in young, healthy adults.

Omega-3 fatty acids (n - 3 FA) may have blood pressure (BP)-lowering effects in untreated hypertensive and elderly patients. The effect of n - 3 FA on BP in young, healthy adults remains unknown. The Omega-3 Index reliably reflects an individuals' omega-3 status. We hypothesized that the Omega-3 Index is inversely associated with BP levels in young healthy adults.

Effects of dietary omega-3 and -6 supplementations on phospholipid fatty acid composition in mice uterus during window of pre-implantation.

Since fatty acid composition of uterus phospholipids is likely to influence embryo implantation, this study was conducted to investigate the effects of dietary omega-3 and -6 fatty acids on implantation rate as well as uterine phospholipid fatty acids composition during mice pre-implantation period. Sixty female mice were randomly distributed into:1) control (standard pellet), 2) omega-3 (standard pellet + 10% w/w of omega-3 fatty acids) and 3) omega-6 (standard pellet + 10% w/w of omega-6 fatty acids)....

Long-chain omega-3 fatty acids and cancer: any cause for concern?

Recently, concerns have been raised with regard to the recommended doses of marine long-chain omega-3 polyunsaturated fatty acids (LC-omega-3 PUFAs) especially in relation to cancer risk and treatment. There is urgent need to clarify this point. This review considers the most recent evidence related to the potential risk of developing cancer with high LC-omega-3 PUFA intakes, and possible research strategies to better elucidate this matter.

Bovine embryo elongation is altered due to maternal fatty acid supplementation.

The pre-implantation period is prone to embryonic losses in bovine. Embryo-maternal communication is crucial to support embryo development. Thereby, factors of the uterine fluid (UF) are of specific importance. The maternal diet can affect the UF composition. Since omega 3 fatty acids (omega 3 FA) are considered to be beneficial for reproduction, we investigated if dietary omega 3 FA affected factors in the UF related to embryo elongation. Angus heifers (n = 37) were supplemented with either 450 g of rume...

Omega-3 supplements reduce self-reported physical aggression in healthy adults.

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 eicosapentaen...

The cardiovascular benefits of indiscriminate supplementation of omega-3 fatty acids; meta-analysis and decision-making approach.

The meta-analysis was conducted to estimate of the cardiovascular benefits of indiscriminate supplementation of omega-3 capsules. The results, expressed in terms of quality adjusted life years (QALY) intuitively understood by the general public, can be the basis for the (personal) decision on whether to take omega-3 supplements.

The phage appeared together with the cultured Weissella ceti during isolation of pathogen from kidney of diseased rainbow trout. The morphological, physiological, proteomic and lytic spectrum were characterized. This phage, named PWc, belonged to the family Siphoviridae and possessed an isometric head (approximat...

Molecular mechanisms of omega-3 fatty acids in the migraine headache.

Migraine is a common chronic inflammatory neurological disease with the progressive and episodic course. Much evidence have shown a role of inflammation in the pathogenesis of migraine. Omega-3 fatty acids are an important components of cell membranes phospholipids. The intake of these fatty acids is related to decrease concentration of C-reactive protein (CRP), proinflammatory eicosanoids, cytokines, chemokines and other inflammation biomarkers. Many of clinical trials have shown the beneficial effect of d...

Editorial: Can omega-3 fatty acids improve executive functioning? Will this reduce ADHD and depression?

Families with children who have neurodevelopmental disorders and mental health problems often opt to use nonmainstream and complementary medicines including dietary supplements. One dietary supplement popular with parents seeking treatment for both depression and ADHD is omega-3 fatty acids. This has led to much research and scientific debate dedicated to examining the efficacy of omega-3 supplementation as a treatment for both depression and ADHD.

Cracking the omega code: hydraulic architecture of the cycad leaf axis.

The leaf axis of members of the order Cycadales ('cycads') has long been recognized by its configuration of independent vascular bundles that, in transverse section, resemble the Greek letter omega (hence the 'omega pattern'). This provides a useful diagnostic character for the order, especially when applied to paleobotany. The function of this pattern has never been elucidated. Here we provide a three-dimensional analysis and explain the pattern in terms of the hydraulic architecture of the pinnately compo...

The reliability of identifying the Omega sign using axial T2-weighted magnetic resonance imaging.

Preoperative identification of the eloquent brain is important for neurosurgical planning. One common method of finding the motor cortex is by localizing "the Omega sign." No studies have tested the reliability of imaging to identify the Omega sign. We identified 40 recent and consecutive patients who had undergone preoperative functional magnetic resonance imaging for identification of the hand motor area prior to tumor resection. We recruited 11 neurosurgical residents of various levels of training and on...

Highly directive switchable nanoantenna array based on dielectric omega particles at terahertz frequencies.

A high-refractive-index dielectric particle with the ability of supporting both electric and magnetic resonances, operating at 1-2 terahertz, is proposed. It is shown that the suggested omega-shaped nanoparticle is able to control the resonance frequencies independently by changing geometrical dimension. It is also demonstrated numerically that an asymmetric omega particle shows a tunable radiation pattern, depending on the incident frequency. The radiation beam can steer in the range of ±30°. The omega p...

Single-step genomic evaluation improves accuracy of breeding value predictions for resistance to infectious pancreatic necrosis virus in rainbow trout.

The aim of this study was to compare the accuracy of breeding values (EBVs) predicted using the traditional pedigree based Best Linear Unbiased Prediction (PBLUP) and the single-step genomic Best Linear Unbiased Prediction (ssGBLUP) for resistance against infectious pancreatic necrosis virus (IPNV) in rainbow trout. A total of 2278 animals were challenged against IPNV and 768 individuals were genotyped using 57 K single nucleotide polymorphism for rainbow trout. Accuracies for both methods were assessed u...

Assessment of the efficacy of omega-3 fatty acids on metabolic and inflammatory parameters in patients with schizophrenia taking clozapine and sodium valproate.

Omega-3 fatty acid (FA) supplementation has been reported to improve several cardio-metabolic risk factors. We aimed to assess the efficacy of omega-3 fatty acids on metabolic and inflammatory indices in patients with schizophrenia who were taking clozapine and sodium valproate. All patients were on a stable dose of 300-400mg of clozapine for 3 months. Subjects were randomized to treatment with either omega-3 fatty acid (4gr/day) or a placebo for 8 weeks. Height, weight, abdominal circumference, serum lipid...

Analysis of the Cochrane Review: Omega-3 Fatty Acids for the Treatment of Dementia. Cochrane Database Syst Rev. 2016;4:CD009002.

Dietary supplementation with omega-3 polyunsaturated fatty acids from fish and plant sources is commonly prescribed as a non-farmacological alternative to improve brain functions and slow down the progression of dementia. This use is mostly based on findings of preclinical studies which established the role of omega-3 polyunsaturated fatty acids in the development and integrity of the brain, as well as epidemiological research that found evidence of malnutrition in patients with dementia. This Cochrane syst...

Oral Omega-3 Supplementation Lowers Intraocular Pressure in Normotensive Adults.

Elevated intraocular pressure (IOP) is the major modifiable risk factor for the sight-threatening eye disease, glaucoma. We investigated whether oral omega-3 supplements affect IOP in normotensive adults.

Water system is a controlling variable modulating bacterial diversity of gastrointestinal tract and performance in rainbow trout.

A two-phase feeding study evaluating performance of rainbow trout and comparing luminal and mucosal gastrointestinal tract (GIT) bacterial community compositions when fed two alternative protein diets in two rearing systems was conducted. Alternative protein diets (animal protein and plant protein diets) balanced with crystalline amino acids: lysine, methionine and threonine or unbalanced, were fed to rainbow trout in two separate water systems (recirculating (RR) and flow-through (FF)) for a period of 16 w...

Biochemical and cognitive effects of docosahexaenoic acid differ in a developmental and SorLA dependent manner.

Beneficial effects of omega-3 fatty acid intake on cognition are under debate as some studies show beneficial effects while others show no effects of omega-3 supplementation. These inconsistencies may be a result of inter-individual response variations, potentially caused by gene and diet interactions. SorLA is a multifunctional receptor involved in ligand trafficking including lipoprotein lipase and amyloid precursor protein. Decreased SorLA levels have been correlated to Alzheimer's disease, and omega-3 f...

Docosahexaenoic acid for reading, working memory and behavior in UK children aged 7-9: A randomized controlled trial for replication (the DOLAB II study).

Omega-3 fatty acids are central to brain-development of children. Evidence from clinical trials and systematic reviews demonstrates the potential of long-chain Omega-3 supplementation for learning and behavior. However, findings are inconclusive and in need of robust replication studies since such work is lacking.

Toxicokinetics of crude oil components in Arctic copepods.

The risk of accidental oil spills in the Arctic is on the rise due to increased shipping and oil exploration activities, making it essential to calibrate parameters for risk assessment of oil spills to Arctic conditions. The toxicokinetics of crude oil components were assessed by exposing one lipid-poor (CIII) and one lipid-rich (CV) stage of the Arctic copepod Calanus hyperboreus to crude oil WSF (water-soluble fraction). Water concentrations and total body residues (BR), as well as lipid volume fractions,...

Treatment with omega-3 polyunsaturated fatty acids does not improve endothelial function in patients with type 2 diabetes and very high cardiovascular risk: A randomized, double-blind, placebo-controlled study (Omega-FMD).

Numerous recent studies conducted in different clinical settings have focused on the benefits of omega-3 polyunsaturated fatty acids (n-3 PUFAs) in the prevention of cardiovascular diseases. There is limited evidence that patients with type 2 diabetes (T2D) and very high cardiovascular risk can also benefit from a high dose of n-3PUFAs, especially those on optimal medical therapy as recommended by the guidelines. The aim of the present study was to assess the impact of high-dose n-3 PUFA treatment on endoth...
