to investigate the impact of overexpression of atnrt2.1 transgene from arabidopsis on nitrate uptake rate and to understand the regulation of endogenous hats by nitrate and glutamine amino acid (gln) in tobacco plants, wild-type and transgenic (f line) plants grown on soil for 4 weeks were transferred to hydroponic culture in a controlled-environment with a 16/8h l:d photoperiod at 24? c/20...

We previously reported that L-glutamine reduces the severity of mucositis caused by chemoradiotherapy in patients with head and neck cancer. However, impact glutamine on anti-tumor effect remains controversial. This study, which included 40 patients, investigated whether influences survival. Radiation therapy (total: 66 or 70 Gy), cisplatin, docetaxel were co-administered for a period 6 weeks. ...

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 composition was me...

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...

Objective(s): Ulcerative colitis (UC) is a kind of complex immune disease, and a major cause of destruction of intestinal barrier and oxidative stress in this field. In this paper, glutamine (Gln) was believed to offer protection against oxidative stress injury in colitis mice.Materials and Methods: Thirty mice were randomly assigned int...

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...
