OBJECTIVE
To study the effect of L-alanyl-L-glutamine (Ala-Gln) on the levels of insulin-like growth factor-1 (IGF-1) and IGF-1 receptor (IGF-1R) in the intestinal tissues of low-birth-weight (LBW) newborn rats with hypoxia/reoxygenation-induced intestinal injury.
METHODS
Pregnant rats were fed with
Glucose and glutamine are essential energy metabolites for brain tumor growth and survival under both normoxic and hypoxic conditions. Both metabolites can contribute their carbons to lipid biosynthesis. We used uniformly labeled [(14)C]-U-D-glucose and [(14)C]-U-L-glutamine to examine the profile
OBJECTIVE
Necrotizing enterocolitis (NEC) is a multifactorial syndrome in the neonate. Enteral feeding practices are an important component of gastrointestinal injury in neonatal NEC. In the present study, we examined the protective effect of oral supplementation with L-glutamine, an important
In clinical conditions, amino acid supplementation is applied to improve contractile function, minimize ischemia/reperfusion injury, and facilitate postoperative recovery. It has been shown that glutamine enhances myocardial ATP/APD (action potential duration) and glutathione/oxidized glutathione
Endothelial cells were obtained from the aortas of Wistar rats by collagenase digestion. Cells were grown to confluence in medium 199 enriched with L-glutamine but without specific growth factors. Cells were subcultured into 35 mm dishes or 25 cm2 flasks coated with fibronectin. For cell growth
Not much is known about effects of gestational alcohol exposure on maternal and fetal cardiovascular adaptations. This study determined whether maternal binge alcohol exposure and L-glutamine supplementation could affect maternal-fetal hemodynamics and fetal regional brain blood flow during the
OBJECTIVE
Hypoxia and the resulting oxidative stress play a major role in postoperative tissue fibrosis. The objective of this study was to determine the effect of l-alanyl-l-glutamine (Ala-Gln) on key markers of postoperative tissue fibrosis: hypoxia-inducible factor (HIF) 1α and type I
Novel nootropic compounds, nooglutyl (N-5-hydroxy(nicotinoyl)-L-glutamine acid, 25 mg/kg/day) and L-pyroglutamyl-D-alanine amide (1 mg/kg/day) administered intracutaneously from the 8th to 20th day of life prevent from movement hyperactivity in "open field", disturbances in ability to training and
Glycyl-L-glutamine (Gly-L-Gln), or beta-endorphin-(30-31) [beta-End-(30-31)], is synthesized through the post-translational processing of beta-End-(1-31). Evidence that gly-L-gln is a prominent end product of beta-End-(1-31) processing in cardioregulatory regions of rat brain prompted us to
Tumor ischemia participates in angiogenesis and cancer progression through cellular responses to hypoxia and nutrient deprivation. However, the contribution of amino acids limitation to this process remains poorly understood. Using serum-free cell culture conditions, we tested the impact of
In order to investigate the effects of L-glutamine on the gut blood flow and oxygen consumption after burn, 14 mini-swines were randomly and equally divided into Non-Gln group and Gln group (which was supplied with L-glutamine, 0.64 g/kg day). Gut blood flow and oxygen consumption were continuously
The virulence of Mycobacterium tuberculosis is intimately related to its distinctive cell wall. The biological significance of poly-α-L-glutamine (PLG), a component in the cell wall of virulent mycobacteria, has not been explored adequately. The focus of this study is to investigate the role of a
The management of sickle cell disease (SCD) and its complications in the COVID-19 era is very challenging. The recurrent sickling process in SCD causes tissue hypoxemia and micro-infarcts, resulting in end organ damage. Since the outbreak of SARS-CoV-2 pandemic, little data has been published about
OBJECTIVE
Serious trauma to the body often is associated with changes in protein metabolism in multiple organs and tissues. Clinically, the catabolic response results in a generalized negative nitrogen balance. Nutrition support has been an important component of the care of seriously traumatized
Hydrogen sulfide (H(2)S), a bacterial metabolite present in the lumen of the large intestine, is able to exert deleterious effects on the colonic epithelium. The mechanisms involved are still poorly understood, the reported effect of sulfide being its capacity to reduce n-butyrate beta-oxidation in
