Dietary long-chain polyunsaturated fatty acids affect plasma and tissue lipids in chickens
… how dietary lipid sources influence lipid and polyunsaturated fatty acid (PUFA) metabolism when fed to young, growing chickens. In the first experiment, commercial meat-type chickens were fed one of four dietary lipids: 1) linseed oil (LO); 2) menhaden oil (MO); 3) soybean oil (SBO); or 4) …

The importance of long chain polyunsaturated fatty acids for fetal immune system maturation and function
Long chain polyunsaturated fatty acids (LCPUFAs) are important structural components in the cell membrane and a deficiency in these fatty acids have been linked to clinical complications. In addition, omega 3 and omega 6 LCPUFAs are biologically active substrates for the synthesis of regulators of …

Effects of dietary alpha linolenic acid on biosynthesis of N-3 long chain polyunsaturated fatty acids in animals.
Omega-3 (n-3) long chain polyunsaturated fatty acids (LCPUFA), particularly eicosapentaenoic acid (EPA, 20:5n-3) and docosahexaenoic acid (DHA, 22:6n-3), are important for normal health as well as growth and brain development in humans. These fatty acids can be consumed in the diet directly, or …

IMPROVING LARVAL SUNSHINE BASS PRODUCTION THROUGH SUPPLEMENTATION OF FEMALE WHITE BASS BROODSTOCK DIETS WITH LONG-CHAIN POLYUNSATURATED FATTY ACIDS
… research has focused primarily on lipid and fatty acid requirements and their effects on reproductive conditioning due to the importance of these nutrients in providing metabolic energy and structural elements, i.e. for phospholipids for embryonic development. Development of suitable …

Investigation on the Antioxidant Capabilities of Spice Extracts in Inhibition of Long Chain Polyunsaturated Fatty Acids Oxidation and Cholesterol
Antioxidant capabilities of the spice extract of ginger, oregano, rosemary and turmeric were evaluated by monitoring inhibition of DHA and EPA in a menhaden fish oil model and cholesterol oxidation model system. The spice extracts were mixed with the fish oil at 1, 2.5 and 5 % (w/w) and 1, 2.5 and …

Human brain lipid fatty acid composition in relation to infant diet
… dying of sudden infant death syndrome. The fatty acid composition was analysed in these tissues by gas liquid chromatography after extraction and derivatisation. The subjects were divided according to their dietary history, either breast or formula feeding. Formula-fed infants were further …

An Investigation into Long-Chain Polyunsaturated Essential Fatty Acids, Event Related Potential Assessments of Brain Function and Behavioural Measures in Children and Adolescents with and without Attention Deficit Hyperactivity Disorder
… PhD research project investigated differences in long-chain polyunsaturated fatty acids (LC-PUFA) between male adolescents with and without ADHD, and the relationship between these and performance and event related potential (ERP) assessments of brain function and clinical behavioural measures. …

The production of VLCPUFAs in plants
Very long-chain polyunsaturated fatty acids (VLCPUFAs) wie Eicosapentaensäure (EPA) oder Docosahexaensäure (DHA) sind gesundheitsfördernde Bestandteile der menschlichen Ernährung. Wegen Überfischung und Verschmutzung der Meere ist Seefisch als die Hauptquelle dieser wichtigen Fettsäuren jedoch …

Oxidation and Textural Characteristics of Butter and Ice Cream with Modified Fatty Acid Profiles
… shown that milkfats containing higher levels of long chain polyunsaturated fatty acids have lower melting points and decreased solid fat contents which leads to softer-textured products. An increased risk of higher oxidation rates can be a disadvantage of high levels of polyunsaturated fatty …

Biomarkers of fat intake
… thesis reviews the previous use of biomarkers of fatty acid intake and concludes that there is a lack of supporting evidence from large randomized controlled trials (RCT) of sufficient duration for their use to be justified. The hypothesis that fatty acid biomarkers are robust indices of the …

Regulation of glucose -6 -phosphate dehydrogenase by polyunsaturated fatty acids in cultured rat hepatocytes
… understand the molecular mechanism(s) by which polyunsaturated fatty acids inhibit gene expression of the lipogenic enzymes. The model enzyme which we are using to study this phenomenon is liver glucose-6-phosphate dehydrogenase (G6PD). In order to determine if regulation of G6PD occurred at a …

Investigating the Relation Between Genetic Variation in FADS1 & FADS2 with the LCPUFA Content of Extracellular Vesicles from Human Milk
… FADS1 and FADS2 may impact the concentrations of long-chain polyunsaturated fatty acids (LCPUFA) in human milk EVs. As integral components of the lipid membrane, the specific composition or balance of LCPUFAs may impact the bioavailability of EVs in newborns consuming human milk. The objective of …

Coastal resources and nutrition among Middle Stone Age hunter-gatherers in the Southwestern Cape
… on the macronutrient, micronutrient and fatty acid content of marine and terrestrial resources available to Middle Stone Age hunter-gatherers in the southwestern Cape, and examines the role of coastal and terrestrial foods in the diets of early modern humans in the region. The collection, …

Computational studies on polyunsaturated fatty acid uptake and its effects on antimicrobial resistance
… cholera, has the ability to uptake and utilize long chain polyunsaturated fatty acids up to 22 carbon atoms long. Before this discovery was made, conventional belief was that fatty acids of greater than 18 carbons long were toxic to bacteria. Further investigations have revealed that this uptake …

Functional Analysis of Dehydratase Domains of a Polyunsaturated fatty acid Synthase from Thraustochytrium sp. by Mutagenesis
Very long chain polyunsaturated fatty acids (VLCPUFAs), such as docosahexaenoic acid (DHA, 22:6-4,7,10,13,16,19) and eicosapentaenoic acid (EPA, 20:5-5,8,11,14,17), are essential for humans and animals since they are parts of the cell membrane and are involved in mediating various physiological …

Evaluation of biomass from the halotolerant microalga Dunaliella salina as an animal feed additive with immune-modulatory activity
… to contain a full complement of essential amino acids. Heavy metals present were found to be below the maximum permitted levels for foodstuffs. The presence of residual carotenoids (0.42 ± 0.012 % AFDW), starch (54.13 ± 0.81 % AFDW) and long-chain polyunsaturated fatty acids (LCPUFAs) such as …

RESOURCE SUBSIDIES ACROSS THE AQUATIC-TERRESTRIAL BOUNDARIES OF TEMPORARY PONDS
… of similar resources in the recipient habitat. Long-chain polyunsaturated fatty acids (LC-PUFAs) are necessary for proper physiological function, are unevenly distributed across the landscape, and animals differ greatly in their ability to synthesize them de novo. This creates the potential for …

Studies on polyunsaturated fatty acid content and lipid peroxidation in preterm infant nutrition from non-maternal sources.
Long-chain polyunsaturated fatty acids (LCPUFAs) are essential for infants’ health and development. Preterm infants have particularly high requirements for LCPUFAs, due to premature interruption of the maternal-foetal transfer. Research suggests that current feeding practices are insufficient to …
