The Synthesis and Characterisation of Long-Chain Fatty Acids
… and positional isomers of monounsaturated fatty acids. The view that there may be hazards associated with such oils have occasionally been expressed. Prior to an investigation of the levels of such acids in human tissue and UK dietary fats, the synthesis of a series of these acids, as …

Effect of Long-Chain Fatty Acids on Anaerobic Digestion
An investigation was carried out to study whether long-chain fatty acids (LCFAs) have an effect on digestion of waste sludge under anaerobic conditions. Four different kinds of LCFAs were used in this study. The 18 carbon series with 0, 1, 2 and 3 double bonds were studied to evaluate the degree of …

The analysis of experimental diets for long chain fatty acids
… to determine the amount and distribution of the fatty acids in those diets. Methods and procedures were developed for extracting the fatty acids from the lyophilized food composite composed of plant foods only. The fatty acids were extracted and methylated. Their methyl esters were separated and …

Systemic and Intracellular Trafficking of Long-chain Fatty Acids in Lactating Dairy Cattle
… are used as ration additives to provide omega-3 fatty acids to dairy cows. Supplementing dairy cows with omega-3 fatty acid-rich feeds does not easily increase quantities in milk fat of dairy cows because polyunsaturated fatty acids are biohydrogenated in the rumen. Lipid encapsulation of omega-3 …

Mechanisms of Western-Diet Induced Endothelial Stiffening: Endothelial CD36 and Long-Chain Fatty Acids
Western diet (WD) refers to a diet high in saturated fat and refined carbohydrates. WD is known to be detrimental to cardiovascular health. These studies present novel insights into the mechanism undergirding WD-associated cardiovascular dysfunction: stiffening (an increase in the elastic modulus) …

Long-Chain Fatty Acids Promote Candida albicans Gut Colonization by Restructuring the Fungal Cell Surface
<p><strong>Long-chain fatty acids promote <em>Candida albicans</em> gut colonization by restructuring the fungal cell surface </strong></p> <p>Musfirat Shubaita, BS</p> <p>Advisory Professor: J. Christian Perez, Ph.D.</p> <p>The yeast <em>Candida albicans</em> is a facultative anaerobe residing in …

Effect of Long Chain Fatty Acids on Anaerobic Digestion of Municiapal Sewage Sludge in Completely Mixed Reactors
… production. However, excessive addition of long chain fatty acid, the major content of FOG, has been reported to have inhibitory effects on the anaerobic digestion process and to cause operational challenges. In this study, high purity long chain fatty acids (LCFAs) including linoleic acid, …

Regulation of tumour necrosis factor receptor expression on neutrophils by arachidonic acid and other long chain fatty acids.
… also lipids, such as the pro-inflammatory 00-6 fatty acid, arachidonic acid (AA) and its metabolites. Cellular activation leads to the release of AA from membrane phospholipids. AA regulates the function of many cell types including neutrophils. In view of the known pro-inflammatory properties …

Response of alfalfa to foliar applications of long-chain fatty acids or seed treatments with Chevron XE-1019
Forage crops grown in many parts of the Appalachian region are restricted in yields as a consequence of shallow soils, low levels of essential nutrients, toxic levels of aluminum, and low pH. Therefore, the successful growth of alfalfa in these regions is dependent on either changing existing …

Alteration of Milk Composition in Dairy Cows Fed Supplemental Fat
… in plasma of most other essential amino acids was decreased, nonesterified fatty acids were increased, and glucose and urea N were not altered. In experiment two, the effects of postruminal profile of fatty acids on intake of nutrients, milk production, and milk protein percentage was …

Carnitine and Altered Lipid Metabolism in Iron-Deficient Rats Pre- and Postweaning (Ketogenesis)
… synthesis of carnitine, thereby shunting long-chain fatty acids away from oxidation and ketogenesis into triglyceride synthesis increasing triglyceride levels in serum and liver. The rationale for carnitine involvement is based on two facts: (1) carnitine synthesis in vitro requires …

Increased Anaerobic Digestion Efficiency via the Use of Thermal Hydrolysis
… via their biogas production with and without long chain fatty acid addition and with or without thermal hydrolysis. This research was further carried out in two stages. First a mixture of unsaturated long chain fatty acids (hydrolyzed and unhydrolyzed) was used. The fatty acid mixture included …

Lipid catabolism in Treponema
Members of the genus, Treponema, require long-chain fatty acids for growth in vitro. Serum, added to culture medium, provides a source of long-chain fatty acids. These fatty acids, however, are esterified to triglycerides, phospholipids, and cholesterol. In this study, the major pathways of complex …

Niacin-lipid interactions in lactating dairy cows
… nicotinic acid (12 g/d), calcium salts of long chain fatty acids (3% diet dry matter), and calcium salts of fatty acids with nicotinic acid. Cows received treatment diets from week 2 to week 14 postpartum.

Control of Salmonella Virulence by Microbiota-Derived and Dietary Fatty Acids
… virulence. In this thesis, I describe how fatty acids, derived from both gut microbiota and diet, contribute to attenuation of virulence of enteric pathogen Salmonella. In Chapter 1, I review how dietary and microbiota metabolites affect different aspects of host-microbe interactions. These …

Investigating the Biostimulating Effects of ESO Addition to a TCE Contaminated Site
… Ã -oxidation, microorganisms can break down the long chain fatty acids in vegetable oil into smaller fatty acids such as acetate, propionate, and butyrate. The fermentation of the oil provides reduced conditions as well as a slow release of hydrogen and carbon into the subsurface. This study …

Effects of feeding increasing dietary concentrations of fat on the performance of lactating dairy cows
… control, no fat; control, 3% calcium salts of long-chain fatty acids (Ca-LCFA); control, 6% Ca-LCFA; and control, 9% Ca-LCFA. Dry matter intake and production of milk, milk protein, and solids-not-fat (SNF) were not altered greatly by feeding up to 6% Ca-LCFA in the diet. Nutrient utilization …

Digestion and utilization of nutrients in diets containing feather meal and (or) supplemental fat by lactating dairy cows
… feed intake, and concentrations of AA and long chain fatty acids in blood plasma. Thirty two Holstein cows began a six week trial at the start of the fourth week of lactation. Diets included a control diet (51% forage, 49% concentrate, 16.8% CP, and 19.1% ADF) and diets containing 2.2% …
