the present study examined the antioxidant defense of glutamine on plasma and liver antioxidant status in broilers under phs with respect to changes in the levels of lipid peroxidation marker malondialdehyde (mda), total antioxidant status (tas) and the activities of anti peroxidative enzymes [superoxide dismutase (sod) and glutathione dependent antioxidant enzymes glutathione peroxidase (gpx)]...

The molecular dynamics and density functional theory (DFT) can be applied to discriminate electrocatalyst’s electron transfer (ET) properties. It will interesting the ET properties of green electrocatalysts such as amino acids. Here, we have used DFT compare electrocatalytic abilities asparagine glutamine at carbon paste electrode interface. Cyclic voltammetric results reveal that activities as...

Regulation of glutamine synthetase activity was studied in a glutamine-independent subclone of the hepatoma tissue culture cell line. In cells of this subclone glutamine synthetase activity was elevated by the synthetic corticosteroid hormone, dexamethasone, and depressed by glutamine. The increase in glutamine synthetase activity due to the addition of dexamethasone and that due to removal of ...

Introduction: The aim of this study was to evaluate effects of 7 day glutamine supplementation on exercise-induced oxidative stress and muscle damage. Methods: Nineteen healthy, nonsmoking, young men were recruited to participate in this study. Participants were randomized in a double-blind placebo-controlled fashion into 2 groups: Glutamine (G group) (n=9) and placebo (P group) (n=10). Subj...

Background: The present study was conducted to investigate the possible effects of L-carnitine and glutamine and their synergistic effects on male soccer athletes. Methods: 28 male soccer players (21.1 ± 0.7 y) were enrolled in a randomized pre and post intervention, double-blind design. Before the intervention, their performances were assessed by Bruce protocol, and their body compositi...

Glutamine carbon entry into the tricarboxylic acid (TCA) cycle was assessed in small intestinal epithelial cells by measuring CO2 production from [1-14C]glutamine, and these data together with [U-14C]glutamine data were used to calculate fractional oxidation rates for glutamine. CO2production from either [1-14C]glutamine or [U-14C]glutamine showed saturation kinetics, and the concentration need...

This study examined the regulation of glutamine synthetase protein levels, in response to changes in external glutamine concentration, in mouse C2C12 skeletal muscle cells. Glutamine, at concentrations as low as 0.25 mmol/L, downregulated endogenous and exogenous (plasmid encoded) glutamine synthetase with maximal effect at 2 mmol/L. Glutamine appears to act by changing the stability of the glu...

  Objective(s): The purpose of the present study was to examine the effects of L-glutamine on electromyographic (EMG) activity of the quadriceps muscle injured by eccentric exercise (EE).   Materials and Methods: Seventeen healthy men (age: 22.35±2.27 yr; body mass: 69.91±9.78 kg; height: 177.08±4.32 cm) were randomly and double-blind study with subjects assigned to either an L-glutamine supple...
