Studies on the fatty acid composition of human serum with special reference to the influence of hormones and other agents
A modified technique for separation of serum free fatty acids (FFA), t riglycerides, phospholipids and cholesterol esters by adsorption chromatography on a system of two columns, silicic acid and Florisil, has been elaborated for preparing samples for gas-liquid chromatographic analysis of serum …

Soybean Oil Deacidification Using Membrane Separation and Supercritical Carbon Dioxide
… of soybean oil triacylgycerols (TAGS) and added free fatty acids (FFA as oleic acid) was used. An evaluation of the solubility of soybean oil, oleic acid and linoleic acid in supercritical carbon dioxide provided the appropriate temperature and pressure conditions to use for the membrane …

Various factors that affect hydrolytic rancidity in rice bran
… active lipases. To assess the loss of quality, free fatty acids (FFA) in raw bran were measured over 48 hour period. Cultivar, farming technique, harvest year, milling conditions and degree of milling (DOM) were the factors examined for their effects on FFA of raw bran. Rice bran samples were …

The effect of free fatty acids on endothelial cells
… (OxLDL) molecules e.g. oxidized polyunsaturated fatty acids (PUFAs), or saturated free fatty acids (FFA) are alone sufficient to decrease endothelial cells. This hypothesis was tested by incubating porcine aortic endothelial cells (PAECs) with various oxidized PUFAs and saturated FFAs. Twenty …

Factors Affecting the Development of Lipase Flavor in Butter
… by acid degree value (ADV), and free fatty acids (FFA) using a colorimetric procedure. Age of the cream had a significant effect (P< .01) on FFA and. ADV .levels, whereas heat treatment .of the cream had a significant effect (P< .01) on flavor only. Storage time had a significant …

Inhibition of Free fatty acid-Induced Insulin Resistance by Rosemary Extract: Investigation of the Mechanisms Involved
Excess of plasma free fatty acids (FFA) are highly associated with insulin resistance and are a major risk factor for the development of type 2 diabetes mellitus. This thesis investigates the effect of rosemary extract and rosemary extract polyphenols carnosic acid (CA), rosmarinic acid (RA) and …

Value of Raisins for Reduction of Oxidative Stress, Endothelial Dysfunction, and Inflammation in Obesity
… molecule-1, sVCAM-1), and metabolic measures (free fatty acids (FFA), triacylglycerol (TAC), glucose, insulin). Urinary 8-isoPGF2α decreased 22% and ORAC increased 3% pre to post interventions combined. Postprandial metabolic responses differed by gender, males surpassed females for several …

The effect of fasting on anti-inflammatory mediators, IL-1RA and IL-1R2, and their role in resistance to sickness behaviors in mice
… signaling. Here we also demonstrate that free fatty acids (FFA) are increased in the plasma as a consequence of fasting. Using palmitic acid injection to mimic fastings FFA increase, we elucidated a novel mechanism by which IL-1R2 is up-regulated. This method showed increased IL-1R2 gene …

Mechanisms underlying lipotoxicity and glucotoxicity in pancreatic islets
… exposure of pancreatic islets to a high level of free fatty acids (FFA) or glucose negatively modulates islet hormone release, the identities of signals mediating these effects are not yet fully clarified. The overall objective of this study was to investigate signal transduction pathways involved …

The supercritical fluid extraction and chromatographic analysis of fatty acids in blue cheese
… is largely due to the short and medium chain fatty acids, methyl ketones and secondary alcohols. The free fatty acids contribute flavor themselves and are also precursors of methyl ketones. Lipase action during the cheese ripening leads to formation of free fatty acids (FFA). The short chain …

A Multi-Organ Role for Nocturnin in Post-Transcriptional Regulation of RNA
… in response to cold by diverting glucose and free fatty acids (FFA) to the mitochondria. In this study, Nocturnin's potential role in post-transcriptional regulation of synaptic plasticity is also investigated. Activity-dependent local protein translation in the dendrites is thought to be an …

The effects of added dietary fat on young exercising horses
… glucose, cholesterol, total serum protein, and free fatty acids (FFA). Muscle biopsies were taken before and after exercise during the SETs on wk 1 and wk 12. Differences between wk 0, 6, and 12 in blood levels were found: lactate (P < .01) and glucose (P < .001) decreased, while cholesterol (P …

Application of chromatographic and spectroscopic techniques in the evaluation of the lipid fraction of animal products
… (CGC) was employed not only to determine the fatty acids profile but also, after solid phase extraction, the amount of free fatty acids (FFA), diglycerides (DG), sterols (cholesterol and phytosterols) and cholesterol oxidation products (COPs). To determine hydroperoxides, primary products of …

Metabolic effects of incremental exercise on Arabian horses fed diets containing corn oil and soy lecithin
… also result in increases in the utilization of free fatty acids for fuel during exercise and sparing of muscle glycogen. Phosphatidylcholine, the main component of lecithins, can influence muscle contraction and improve endurance capacity during exercise. When it is combined with corn oil in a …

Carbohydrate loading and its effect on ECG responses
… No changes were noted in blood pressures, serum free fatty acids (FFA) and post exhaustive run body weights for diets not pre/post exercise bouts. Serum glucose was significantly higher for the pre-run high-CHO diet when compared to the mixed and high-fat diets pre-run values, yet it remained …

Impact of the chromatin remodeller SMARCAD1 on murine intestinal intraepithelial lymphocyte and white adipose tissue biology.
… these mice showed elevated triglyceride (TG) and free fatty acids (FFA) levels. Transcriptomic analysis by RNA-seq of whole-WAT revealed an elevation in macrophage-related markers in knockout mice, which was confirmed by flow cytometry. As a number of reports have implicated SMARCAD1 in stem cell …

Effects of UV Irradiation on the Reduction of Bacterial Pathogens and Chemical Indicators of Milk
… sensory studies indicated that the increase of free fatty acids (FFA) was not enough to cause detectable off-odors in the milk. Solid phase microextraction and gas chromatography (SPME-GC) was utilized to quantify the production of volatile compounds that were formed due to UV processing. The …
