Plasma polyunsaturated fatty acid profile and delta-5 desaturase activity are altered in patients with type 2 diabetes.

The association between imbalance of polyunsaturated fatty acids (PUFAs), especially low plasma n-3 to n-6 PUFA ratio, and risk of cardiovascular diseases is well known. A balance of plasma PUFAs is determined not only by dietary fatty acid intake, but also by the endogenous fatty acid metabolism, which could be dysregulated by diabetes. In this study, we investigated the plasma n-3 and n-6 PUFA profile and fatty acid desaturase activity in patients with type 2 diabetes (T2D).

Anticolorectal cancer activity of the omega-3 polyunsaturated fatty acid eicosapentaenoic acid.

Oral administration of the omega-3 fatty acid eicosapentaenoic acid (EPA), as the free fatty acid (FFA), leads to EPA incorporation into, and reduced growth of, experimental colorectal cancer liver metastases (CRCLM).

Prevalence and mechanism of polyunsaturated aldehydes production in the green tide forming macroalgal genus Ulva (Ulvales, Chlorophyta).

Lipoxygenase/hydroperoxide lyase mediated transformations convert polyunsaturated fatty acids into various oxylipins. First, lipoxygenases catalyze fatty acid oxidation to fatty acid hydroperoxides. Subsequently, breakdown reactions result in a wide array of metabolites with multiple physiological and ecological functions. These fatty acid transformations are highly diverse in marine algae and play a crucial rule in e.g, signaling, chemical defense, and stress response often mediated through polyunsaturated...

Erythrocyte Phospholipid and Polyunsaturated Fatty Acid Composition in Diabetic Retinopathy.

Long chain polyunsaturated fatty acids (LCPUFAs) including docosahexaenoic acid and arachidonic acid are suspected to play a key role in the pathogenesis of diabetes. LCPUFAs are known to be preferentially concentrated in specific phospholipids termed as plasmalogens. This study was aimed to highlight potential changes in the metabolism of phospholipids, and particularly plasmalogens, and LCPUFAs at various stages of diabetic retinopathy in humans.

Five Decades with Polyunsaturated Fatty Acids: Chemical Synthesis, Enzymatic Formation, Lipid Peroxidation and Its Biological Effects.

Dietary Fat and Fatty Acid Profile Are Associated with Indices of Skeletal Muscle Mass in Women Aged 18-79 Years.

Age-related loss of skeletal muscle mass results in a reduction in metabolically active tissue and has been related to the onset of obesity and sarcopenia. Although the causes of muscle loss are poorly understood, dietary fat has been postulated to have a role in determining protein turnover through an influence on both inflammation and insulin resistance. This study was designed to investigate the cross-sectional relation between dietary fat intake, as dietary percentage of fat energy (PFE) and fatty acid ...

Interactions Between the Dietary Polyunsaturated Fatty Acid Ratio and Genetic Factors Determine Susceptibility to Pediatric Crohn's Disease.

Increased dietary ratios of ω6/ω3 poly-unsaturated fatty acids (PUFAs) have been implicated in pathogenesis of Crohn's disease (CD), but epidemiologic data are limited. We investigated whether variants of genes that control PUFA metabolism (CYP4F3, FADS1, and FADS2), along with the dietary ratio of ω6/ω3, confers susceptibility to CD. Based on data from 182 children newly diagnosed with CD and 250 controls, we found that children who consumed a higher dietary ratio of ω6/ω3 were susceptible for CD if ...

This study was conducted to compare fatty acid composition and content of conjugated linoleic acid (CLA) in different regions of sheep carcasses. Lambs of the Dağlıç breed were used for this purpose. Subsequent to a 68-day period of intensive fattening, fatty acids were examined in samples taken from the legs, shoulders, breasts, and ribs of lamb carcasses. According to the analysis, in leg, shoulder, breast, and rib, respectively, total saturated fatty acids (SFA) were found to be 40.38, 42.69, 42.56, a...

Cytochrome P450 2C8 ω3-Long-Chain Polyunsaturated Fatty Acid Metabolites Increase Mouse Retinal Pathologic Neovascularization--Brief Report.

Regulation of angiogenesis is critical for many diseases. Specifically, pathological retinal neovascularization, a major cause of blindness, is suppressed with dietary ω3-long-chain polyunsaturated fatty acids (ω3LCPUFAs) through antiangiogenic metabolites of cyclooxygenase and lipoxygenase. Cytochrome P450 epoxygenases (CYP2C8) also metabolize LCPUFAs, producing bioactive epoxides, which are inactivated by soluble epoxide hydrolase (sEH) to transdihydrodiols. The effect of these enzymes and their metabol...

Fatty Acid and Volatile Oil Compositions of Allomyrina dichotoma Larvae.

Thirty-two different volatile oils were identified from Allomyrina dichotoma (A. dichotoma) larvae by gas chromatography/mass spectrometry (GC/MS).

Methods: One hundred and seventy Taiwanese diabetic patients were enrolled. The correlations between biochemical data and diet composition (from 24-hour recall of intake food) of these patients were explored (Spearman correlation, p < 0.05). Diet components were also correlated with each other to show diet characteristics of diabetic patients in Taiw...

Serum level changes of long chain-polyunsaturated fatty acids in patients undergoing periodontal therapy combined with one year of omega-3 supplementation: a pilot randomized clinical trial.

We aimed to investigate the impact of nonsurgical periodontal treatment combined with one-year dietary supplementation with omega (ω)-3 on the serum levels of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), docosapentaenoic acid (DPA), and arachidonic acid (AA).

Role of docosahexaenoic Acid treatment in improving liver histology in pediatric nonalcoholic Fatty liver disease.

Nonalcoholic fatty liver disease (NAFLD) is one of the most important causes of liver-related morbidity and mortality in children. Recently, we have reported the effects of docosahexaenoic acid (DHA), the major dietary long-chain polyunsaturated fatty acids, in children with NAFLD. DHA exerts a potent anti-inflammatory activity through the G protein-coupled receptor (GPR)120. Our aim was to investigate in pediatric NAFLD the mechanisms underlying the effects of DHA administration on histo-pathological aspec...

Fatty acid metabolism: Implications for diet, genetic variation, and disease.

Cultures across the globe, especially Western societies, are burdened by chronic diseases such as obesity, metabolic syndrome, cardiovascular disease, and cancer. Several factors, including diet, genetics, and sedentary lifestyle, are suspected culprits to the development and progression of these health maladies. Fatty acids are primary constituents of cellular physiology. Humans can acquire fatty acids by de novo synthesis from carbohydrate or protein sources or by dietary consumption. Importantly, regulat...

Interaction of Dietary Fatty Acids with Tumour Necrosis Factor Family Cytokines during Colon Inflammation and Cancer.

Intestinal homeostasis is precisely regulated by a number of endogenous regulatory molecules but significantly influenced by dietary compounds. Malfunction of this system may result in chronic inflammation and cancer. Dietary essential n-3 polyunsaturated fatty acids (PUFAs) and short-chain fatty acid butyrate produced from fibre display anti-inflammatory and anticancer activities. Both compounds were shown to modulate the production and activities of TNF family cytokines. Cytokines from the TNF family (TNF...

Effect of dietary n-3 polyunsaturated fatty acids on transcription factor regulation in the bovine endometrium.

Dietary n-3 polyunsaturated fatty acid (n-3 PUFA) supplementation is postulated to have positive effects on fertility. The impact of dietary n-3 PUFA supplementation on physiological and biochemical processes involved in reproduction is likely to be associated with significant alterations in gene expression in key reproductive tissues which is in turn regulated by transcription factors. Beef heifers were supplemented with a rumen protected source of either a saturated fatty acid or high n-3 PUFA diet per an...

The impact of dietary long chain polyunsaturated fatty acids on bone and cartilage in gilts and sows.

Dietary long chain polyunsaturated fatty acids (PUFA) including arachidonic acid (ARA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) are precursors for several inflammatory mediators. The objective of this study was to characterize the effects of dietary PUFA supplementation on bone, cartilage, and synovial fluid in 2 ages of pigs. Sows and gilts were fed either control corn/soybean meal based diets, or the control diet supplemented with PUFA from Gromega (JBS United, Sheridan, IN). Sows were...

Changes in some physicochemical properties and fatty acid composition of irradiated meatballs during storage.

Meatball samples were irradiated using a (60)Co irradiation source (with the dose of 1, 3, 5 and 7 kGy) and stored (1, 2 and 3 weeks at 4°C) to appraise some physicochemical properties and the fatty acid composition. The physicochemical results showed no significant differences in moisture, protein, fat and ash content of meatballs because of irradiation. However, total acidity, peroxide and thiobarbituric acid (TBA) values increased significantly as a result of irradiation doses and storage period. The ...

Valproate-Induced Liver Injury: Modulation by the Omega-3 Fatty Acid DHA Proposes a Novel Anticonvulsant Regimen.

The polyunsaturated, ω-3 fatty acid, docosahexaenoic acid (DHA), claims diverse cytoprotective potentials, although via largely undefined triggers. Thus, we currently first tested the ability of DHA to ameliorate valproate (VPA)-evoked hepatotoxicity, to modulate its anticonvulsant effects, then sought the cellular and molecular basis of such actions. Lastly, we also verified whether DHA may kinetically alter plasma levels/clearance rate of VPA.

Long-chain polyunsaturated fatty acid supplementation had no effect on body weight but reduced energy intake in overweight and obese women.

Longer-chain polyunsaturated fatty acids may have greater appetite-suppressing effects than shorter-chain, monosaturated, and saturated fatty acids. Because fish oils are predominantly composed of n-3 long-chain polyunsaturated fatty acid and may assist in the treatment of obesity comorbidities, their effect on body weight and body mass index is of interest. We hypothesized that daily supplementation with docosahexaenoic acid (DHA)-rich oil would reduce energy intake and body weight in overweight and obese ...

The Role of Polyunsaturated ω-3 Fatty Acid Eicosapentaenoic Acid-Derived Resolvin E1 (RvE1) in Bone Preservation.

Resolvin E1 (RvE1) is a recently discovered lipid-derived mediator that is endogenously synthesized from the polyunsaturated fatty acid eicosapentaenoic acid. RvE1 is locally generated in response to inflammation where it enhances the resolution phase of inflammation by diminishing neutrophil chemotaxis and by enhancing nonphlogistic macrophage-directed clearance of apoptotic neutrophils. RvE1 was also found to be effective in preventing and restoring bone loss in the inflammatory bone disease periodontitis...
