OBJECTIVE
To investigate the effect of L-alanyl-L-glutamine (L-Ala-Gln) preconditioning in an acute cerebral ischemia/reperfusion (I/R) model in gerbils.
METHODS
Thirty-six Mongolian gerbils (Meriones unguiculatus), (60-100g), were randomized in 2 groups (n=18) and preconditioned with saline 2.0 ml
The pathogenesis of brain edema in acute liver failure is poorly understood. We have previously shown that rats with ischemic acute liver failure (portacaval anastomosis followed by hepatic artery ligation) exhibit brain edema and intracranial hypertension, with swelling of cortical astrocytes as
Corneal endothelial disease is a global sight-threatening disease, and corneal transplantation using donor corneas remains the sole therapeutic option. A previous work demonstrated that N (2)-alanyl-glutamine (Ala-Gln) protected against apoptosis and cellular stress, and maintained intestinal tissue
BACKGROUND
Mucosal barrier injury during intestinal preservation (IP) and transplantation favors life-threatening infections. Luminal delivery of solutions containing amino acids or polyethylene glycols (PEGs) may improve preservation results and reduce this injury. We tested if solutions containing
OBJECTIVE
Triamcinolone acetonide (TA) is a corticosteroid that can be used in the treatment of cystoid macular edema (CME) and other ocular inflammatory conditions. This study aims to investigate the degree of cytotoxic effect of TA on human retinal pigment epithelium (ARPE19 cell line) and to
The human genome project has increased the demand for simple experimental systems that allow the impact of gene manipulations to be studied under controlled ex vivo conditions. We hypothesized that, in contrast to adult hearts, neonatal hearts allow long-term perfusion and efficient gene transfer ex
OBJECTIVE
We aimed to evaluate the effects of β-hydroxy-β-methylbutyrate, L-glutamine, and L-arginine (HMB/Glu/Arg) on radiation-induced acute inflammation and mucosal atrophy in the oral mucosa.
METHODS
Twenty-eight rats were divided into four groups. group (G) 1 was defined as control group, and
BACKGROUND
Deltamethrin (DLM) is an insecticide commonly used to protect agricultural crops against pests. QT prolongation with malignant ventricular arrhythmias are amongst the most common cardiovascular complications. DLM intoxication cause decreased level of antioxidant enzymes. Glutamine is the
SN1, a system N amino acid transporter specific for astrocytes, is mainly responsible for export of newly synthesized L-glutamine from the cells. Astrocytic retention of L-glutamine which plays a critical role in ammonia-induced astrocytic swelling resulting in brain edema, could be tentatively
Hyperammonemia is mainly found in hepatic encephalopathy and in genetic defects of the urea cycle or other pathways of the intermediary metabolism. Clinically a difference has to be made between chronic moderate hyperammonemia and acutely increased concentrations. Pathogenetic mechanisms of ammonia
