BACKGROUND In previous studies, the neuroprotective effect of 17β-estradiol in diffuse traumatic brain injury has been shown. This study used ICI 182,780, a non-selective estrogen receptor antagonist, to test the hypothesis that the neuroprotective effect of 17β-estradiol in traumatic brain injury is mediated by the estrogen receptors. METHODS The ovariectomized rats were divided into eight g...
BACKGROUND AND PURPOSE Tissue substrates for action of neuroprotective agents may be absent in a significant proportion of strokes. Pathophysiological heterogeneity is a possible contributor to negative neuroprotective trials. METHODS Stroke subtypes and their individual outcomes in neuroprotective trial control populations were used to derive models incorporating accuracy of clinical classif...
objective(s) previous studies have demonstrated that pretreatment with alpha-tocotrienol (a-tct) can reduce ischemic damage in mice following middle cerebral artery (mca) occlusion. it is also reported to decrease stroke- dependent brain tissue damage in 12-lox-deficient mice and spontaneously hypertensive rats. in the present study, the neuroprotective effects of a-tct and rosiglitazone (rgz) ...
Retinal neurodegeneration is an early event in the pathogenesis of diabetic retinopathy (DR). Since glucagon-like peptide 1 (GLP-1) exerts neuroprotective effects in the central nervous system and the retina is ontogenically a brain-derived tissue, the aims of the current study were as follows: 1) to examine the expression and content of GLP-1 receptor (GLP-1R) in human and db/db mice retinas; ...

BACKGROUND AND PURPOSE The angiotensin II type 2 receptor (AT(2)R) is implicated to be neuroprotective in stroke, although this premise has not been directly tested. Therefore, we have examined the neuroprotective effect of AT(2)R stimulation after intracerebroventricular administration of AT(2)R agonist CGP42112 in a conscious rat model of stroke. METHODS Spontaneously hypertensive rats were...
traumatic brain injuries may cause some neurological deficits, such as altered level of consciousness or coma, sensory-motor dysfunction, and seizure attacks. the neuroprotective effect of progesterone and erythropoietin has been shown in different types of brain injuries and cerebral ischemia. this study aims to evaluate the probable additional neuroprotective effects of progesterone and eryth...
As the major neurotransmitter in the mammalian central nervous system (CNS), excessive extracellular glutamate (Glu) can activate the Glu receptors and neuronal calcium (Ca2+) overload, then produce neurotoxicity, which is a common pathway for neuronal injury or death, and is associated with acute and chronic neurodegenerative diseases. Therefore, it has been a therapeutic strategy to investiga...
The neuroprotective properties of drugs binding to FKBP12, with and without subsequent inhibition of calcineurin, were investigated in rat models of ischemic embolic stroke. Drug effects on brain infarct volumes evoked by transient middle cerebral artery occlusion (MCAO) and by permanent MCAO were determined in vivo by T2-weighted magnetic resonance imaging and post mortem by triphenyltetrazoli...
The combination of memantine, an N-methyl-d-aspartate (NMDA) receptor antagonist, with an acetylcholinesterase inhibitor (AChEI) is the current standard of care in Alzheimer's disease (AD). Galantamine, an AChEI currently marketed for the treatment of AD, exerts memory-enhancing and neuroprotective effects via activation of nicotinic acetylcholine receptors (nAChRs). Here, we investigated the n...
