Various Factors Affecting Plasma Free Amino Acid Concentrations in the Horse
… the diet and sample location, on the resulting plasma free amino acid (PFAA) concentrations in the horse. Six horses were individually fed a complete pelleted diet of 15.1% C.P. at a rate of 1.75% of body weight in either one, two or six meals daily. Horses receiving six meals had more constant …

Movement of plasma free, erythrocyte free, peptide and serum protein amino acids across the gastrointestinal tract and liver of calves
Peptide, plasma free, erythrocyte free and serum protein amino acid arteriovenous differences were quantified across the gastrointestinal tract (GIT) and liver of growing calves during a "steady state" and fasting metabolism. Six Holstein steer calves (136 kg) surgically equipped with cannulae in …

USING THE PLASMA FREE AMINO ACID DOSE RESPONSE METHOD TO DETERMINE METABOLIZABLE PROTEIN CONCENTRATIONS OF LYSINE AND METHIONINE IN RUMEN PROTECTED SUPPLEMENTS
… studies was to propose the acceptance of the plasma free AA dose-response technique as a standardized methodology for evaluating RPAA in lactating dairy cows. Thirteen dose-response Latin square studies using ruminally-cannulated multiparous Holstein cows were conducted. Regression analysis of …

Metal-assisted chemical etching of III-V semiconductors for advanced optoelectronic device fabrication
… is metal-assisted chemical etching (MacEtch), a plasma-free wet etching method that utilizes a metal catalyst in order to enhance directional etching of a semiconductor. MacEtch has found its place in etching a wide variety of semiconductor materials, which expands its application beyond Si …

Investigating the role of transcription factors Nrf2 and Pparα in hepatic lipid metabolism during fasting
… significantly higher, with corresponding lower plasma free fatty acid concentration than their WT counterparts. Upon genetic knockout of Pparα the target genes which were upregulated in the Nrf2-/- animals were not induced in response to fasting, indicating that their increased expression in …

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 …

Time Delayed Protein Complementation
… male rats by measuring growth rates as well as plasma and tissue free amino acids. Diets of pinto beans with rice, corn or wheat were pair-fed in combination or alternating 4 times a day at 6 and 11 am, and 4 and 9 pm for 4 weeks. Plasma, liver and muscle samples were obtained 2 hours …

The acute effects of differential dietary fatty acids on PDHa activity in human skeletal muscle at the onset of exercise
… and following fat loading and at 1 min exercise. Plasma free fatty acids increased from 0.15 ± 0.07 to 0.54 ± 0.19 mM over 5 hours with SFA and from 0.1 1 ± 0.04 to 0.35 ±0.13 mM with PUFA. PDHa activity was unchanged following fat loading, but increased at the onset of exercise in the SFA trial, …

Responses to abomasal infusion of casein, hydrolyzed casein or methionine-lysine and dietary protein degradability in lactating cows
… the caseins in their effects on individual plasma free amino acids. Methionine-lysine infusion increased plasma lysine and taurine, a metabolite of methionine, suggesting that infused methionine was extensively metabolized. Total duodenal nitrogen flow and non-microbial nitrogen flow tended …

Excess leucine in diets for growing pigs negatively affects growth performance, nitrogen balance, and metabolism of branched-chain amino acids and tryptophan
… value of dietary protein was also observed, and plasma urea N (PUN) increased (linear, P < 0.05) as dietary Leu increased. A linear reduction (P < 0.05) in hypothalamic serotonin was observed with increasing dietary Leu. In experiment 2, the objective was to determine effects of dietary Ile and …

Transport and exchange of amino acids from plasma, erythrocytes, peptides and serum proteins across the hindlimb of calves fed soy or urea purified diets
Plasma and erythrocyte (RBC) free amino acids and plasma peptide and serum protein amino acid concentrations and arteriovenous (A/V) differences across the hindlimbs were determined on growing Holstein steer calves (130 kg) fed purified diets containing scy protein or urea as the sole source of …

The Roles of Free Fatty Acids and Inflammation in β-Cell Dysfunction
… to the adverse effects of chronically elevated plasma free fatty acids on β-cell function and mass and plays an important role in type 2 diabetes. The objective of my thesis was to investigate the role of inflammation in fat-induced β-cell dysfunction in vivo. I used in vivo models of 48h …

The effects of linoleate on insulin action in skeletal muscle cells
… in animal models have shown that increases in plasma free fatty acids (FFAs) are associated with reduced IRS-1-signalling, and so it has been postulated that elevated FFA cause insulin resistance by activating pathways that negatively regulate insulin action, including hyper-phosphorylation of …
