objective(s):global cerebral ischemia-reperfusion injury causes loss of pyramidal cells in ca1 region of hippocampus. in this study, we investigated the possible neuroprotective effects of the ethanol extract of cyperus rotundus (eecr) on a model of global transient ischemia in rat, by evaluating the pathophysiology of the hippocampal tissue and spatial memory. materials and methods: treatment ...

Evaluating the impact of Viola spathulata in a rat model brain ischemia/reperfusion by influencing expression level caspase-3 and cyclooxygenase-2

objective(s) opioid abuse is still remained a major mental health problem, a criminal legal issue and may cause ischemic brain changes including stroke and brain edema. in the present study, we investigated whether spontaneously withdrawal syndrome might affect stroke outcomes. materials and methods addiction was induced by progressive incremental doses of morphine over 7 days. behavioral signs...

background: brain hypoxia-ischemia is a human neonatal injury that is considered a candidate for stem cell therapy. methods: the possible therapeutic potential of human umbilical cord blood (hucb) stem cells was evaluated in 14-day-old rats subjected to the right common carotid occlusion, a model of neonatal brain hypoxia-ischemia. seven days after hypoxia-ischemia, rats received either saline ...

Introduction: ischemic preconditioning is one of the most important mechanisms, responsible for the increased brain resistance after stroke. One of the most important candidates to ischemia preconditioning is intermittent normobaric hyperoxia. In this study, the effect of intermittent normobaric hyperoxia on the expression of UCP2 was investigated in a stroke model. Methods: Rats were divid...

in the mammalian, there are three ncx genes (ncx1, ncx2, ncx3), which their three proteins are differentially expressed in distinct regions of the central nervous system, where they might underlie different physiological and pathophysiological functions. ncx is a nine-transmembrane protein which is distributed in the brain widely. ncx operates in a bidirectional way, and exchanges ca2+ and na+ ...

Introduction: Nucleobinding-2 (NUCB2) or nesfatin-1, a newly identified anorexigenic peptide, has antioxidant, anti-inflammatory, and anti-apoptotic properties. Brain ischemia-reperfusion induces irreversible damages, especially in the hippocampus area. However, the therapeutic effects of NUCB2 have not been well investigated in cerebral ischemia. This study was designed for the first time to i...

background: probiotics are microorganisms that may influence brain function via altering brain neurochemistry. new research evidence suggests that probiotic bacteria might protect tissue damage through diminishing the production of free radicals and/or inflammatory cytokines. therefore, this study was designed to evaluate the effects of probiotic bacteria on the prevention or reduction of brain...
