The objective of the study was to ascertain whether human health beneficial omega-3 long-chain (≥C20) polyunsaturated fatty acid (n-3 LC-PUFA) content in heart, kidney and liver can be enhanced by supplementing prime lambs with graded levels of canola and flaxseed oil. Health status of the lambs, as a consequence of the supplementation, was also investigated by examining their plasma metabolites. Sixty purebred and first-cross lambs were allocated to one of five treatments of lucerne hay basal diet supplemented with isocaloric and isonitrogenous wheat-based pellets without oil inclusion (Control) or graded levels of canola oil at 2...

Depression, anxiety and other affective disorders are globally widespread and severely debilitating human brain diseases. Despite their high prevalence and mental health impact, affective pathogenesis is poorly understood, and often remains recurrent and resistant to treatment. The lack of efficient antidepressants and presently limited conceptual innovation necessitate novel approaches and new drug targets in the field of antidepressant therapy. Areas covered: Herein, the authors discuss the emerging role of neuro-immune interactions in affective pathogenesis, which can become useful targets for CNS drug discovery, including modulating neuroinflammatory pathways to alleviate affective pathogenesis...

New generation vaccines, based on isolated antigens, are safer than traditional ones, comprising the whole pathogen. However, major part of purified antigens has weak immunogenicity. Therefore, elaboration of new adjuvants, more effective and safe, is an urgent problem of vaccinology. Tubular immunostimulating complexes (TI-complexes) are a new type of nanoparticulate antigen delivery systems with adjuvant activity. TI-complexes consist of cholesterol and compounds isolated from marine hydrobionts: cucumarioside A2-2 (CDA) from Cucumaria japonica and monogalactosyldiacylglycerol (MGDG) from marine algae or seagrass...

Oxidative stress-induced growth inhibitor 1 (OSGIN1), a tumor suppressor, inhibits cell proliferation and induces cell death. N-6 and n-3 PUFAs protect against breast cancer, but the molecular mechanisms of this effect are not clear. We investigated the effect of n-6 and n-3 PUFAs on OSGIN1 expression and whether OSGIN1 is involved in PUFA-induced apoptosis in breast cancer cells. We used 100 μM of n-6 PUFAs including arachidonic acid, linoleic acid, and gamma-linolenic acid and n-3 PUFAs including alpha-linolenic acid, eicosapentaenoic acid, and docosahexaenoic acid (DHA)...

Periparturient dairy cows experience an increased incidence and severity of several inflammatory-based diseases such as mastitis and metritis. Factors associated with the physiological adaptation to the onset of lactation can impact the efficiency of the inflammatory response at a time when it is most needed to eliminate infectious pathogens that cause these economically important diseases. Oxidative stress, for example, occurs when there is an imbalance between the production of oxygen radicals during periods of high metabolic demand and the reduced capabilities of the host's antioxidant defenses...

The experiment was conducted to test the hypothesis that the replacement of cereal with low-starch feed ingredients in lambs' finishing diets supplemented with oils could prevent the accumulation of -10-18:1 in meat. Forty lambs were fed 1 of 4 diets supplemented with soybean oil (5.9%) and fish oil (1%) for 6 wk before slaughter. The control (CON) diet contained 43% barley, and in the other diets, barley was completely replaced by dehydrated citrus pulp (DCP), dehydrated sugar beet pulp (DBP), or soybean hulls (SH)...

REVIEW
Kayla R Zehr, Mary K Walker
Epidemiology studies and clinical trials show that omega-3 polyunsaturated fatty acids (n-3 PUFAs) can prevent atherosclerotic morbidity and evidence suggests this may be mediated by improving endothelial dysfunction. Endothelial dysfunction is characterized by reduced vasodilation and a pro-inflammatory, pro-thrombotic state, and is an early pathological event in the development of atherosclerosis. Flow-mediated dilation (FMD), a gold standard for assessing endothelial dysfunction, is a predictor of future cardiovascular events and coronary heart disease risk...

Many northern Inuit communities rely on traditional food as major source of nourishment. An essential part of the traditional Arctic diet is marine mammals such as ringed seals or beluga. Being top predators, these animals are often highly contaminated with various toxins. In contrast, some tissues of marine mammals are also characterized by high amounts of n3-PUFAs (omega-3 polyunsaturated fatty acids). Here, we try to balance the risks associated with the consumption of different tissue types of ringed seals in terms of the neurotoxin monomethylmercury (MMHg) with the benefits of consumption due to high n3-PUFA concentrations...

Dietary deficiency of n-3 polyunsaturated fatty acids (PUFAs) is involved in the pathophysiology and etiology of major depressive disorder. Supplementation with docosahexaenoic acid (DHA) exerts antidepressant-like effect; however, the molecular mechanism of DHA action remains unclear. Here we examined the effects of DHA on the modulation of glial cell line-derived neurotrophic factor (GDNF), which is essential for neural development, plasticity, neurogenesis, and survival. We demonstrated that DHA treatment significantly increased GDNF release in a concentration dependent manner in rat C6 glioma cells (C6 cells) and primary cultured rat astrocytes, which is also associated with increased expression of GDNF mRNA...

The quality of dietary lipids in the maternal diet can programme the offspring to diseases in later life. We investigated whether the maternal intake of palm oil or interesterified fat, substitutes for trans-unsaturated fatty acids (FA), induces metabolic changes in the adult offspring. During pregnancy and lactation, C57BL/6 female mice received normolipidic diets containing partially hydrogenated vegetable fat rich in trans-unsaturated fatty acids (TG), palm oil (PG), interesterified fat (IG) or soyabean oil (CG)...

Background: Replacement of saturated fatty acids (SFAs) with unsaturated fatty acids (UFAs), especially polyunsaturated fatty acids (PUFAs), has been associated with a lower risk of ischemic heart disease (IHD). Whether this replacement is beneficial for drug-treated patients with cardiac disease is not yet clear.Objective: In a prospective study of Dutch patients with cardiac disease (Alpha Omega Cohort), we examined the risk of cardiovascular disease (CVD) and IHD mortality when the sum of SFAs and trans fatty acids (TFAs) was theoretically replaced by total UFAs, PUFAs, or cis monounsaturated fatty acids (MUFAs)...

We estimated the heritabilities (h 2) and genetic and phenotypic correlations among individual and groups of fatty acids, as well as their correlations with six important carcass and meat-quality traits in Korean Hanwoo cattle. Meat samples were collected from the longissimus dorsi muscles of 1000 Hanwoo steers that were 30-month-old (progeny of 85 proven Hanwoo bulls) to determine intramuscular fatty acid profiles. Phenotypic data on carcass weight (CWT), eye muscle area (EMA), back fat thickness (BFT), marbling score (MS), Warner-Bratzler shear force (WBSF) and intramuscular fat content (IMF) were also investigated using this half-sib population...

Profound alterations in the lipid profile of raft and non-raft plasma membrane microdomains were found when RAW264.7 macrophages were supplemented with polyunsaturated fatty acids (PUFAs) in physiologically relevant concentrations. For the first time lipids in the detergent-free isolated membrane domains of phagocytic immune cells were characterized by mass spectrometry. The extent of remodeling of the membrane lipids differed with different n3 and n6 PUFA supplements. The mildest effects were detected for -linolenic acid (LNA) and linoleic acid (LA), the C18 precursors of the n3 and n6 families, respectively...

BACKGROUND: Homocystinuria due to cystathionine beta synthase (CBS) deficiency presents with a wide clinical spectrum. Treatment by the enteral route aims at reducing homocysteine levels by using vitamin B6, possibly methionine-restricted diet, betaine and/or folate and vitamin B12 supplementation. Currently no nutritional guidelines exist regarding parenteral nutrition (PN) under acute conditions. METHODS: Exhaustive literature search was performed, in order to identify the relevant studies describing the pathogenesis and nutritional intervention of adult classical homocystinuria requiring PN...
