Members of the Bcl-2 proto-oncogene family have been identified as major modulators of programmed cell death, with Bcl-2 gene products either enhancing or diminishing the likelihood of neuronal survival. This regulation appears to be essential to normal brain development, where programmed cell death may eliminate up to 50% of neurons as a part of selective pruning during formation of neuronal n...

Objective(s): Paeoniflorin (PF) has anti-oxidation, anti-inflammation, anti-apoptosis, and neuroprotection pharmacological effects against ischemic injury. The aim of the present study was to investigate the neuroprotection mechanisms of PF in cerebral ischemia-reperfusion injury rats.Materials and Methods: We established an animal model of cerebral infarct by occlusion of the middle cerebral a...

alzheimer’s disease (ad) is a neurodegenerative disease that was characterized with deposit of beta amyloid (aβ) aggregate in senile plaque. oxidative damage to neurons and loss of cholinergic neurons in forebrain region are observed in this disease. melissa officinalis is a medicinal plant from lamiaceae family, used traditionally in the treatment of cognitive disorders. it has cholinomimetic ...

although uncommon, traumatic optic neuropathy (ton) is an important cause of visual loss. different therapeutic approaches including different dosages of steroids, surgical decompression of optic canal and observation alone have been suggested but there has been no conclusive evidence to establish a standard approach to this devastating cause of visual loss. to determine the effectiveness of in...

objective: recent studies have shown that the use of prolonged and intermittent normobaric hyperoxia (95%) decrease the infarct volume of stroke. the aim of current study was to study the effect of an oxygen radicals-scavenger applied during intermittent normobaric hyperoxia on infarct volume in the rat brain and neurologic deficit. materials and methods: male wistar rats (250-350 g) were divi...

background and objective: sensory neurons have critical role in improvement of functional outcome of any neuroprotective strategy. the herbal medicine nepeta menthoides has been reported to have anti-apoptotic effect on axotomized spinal motoneurons. in the present study, the putative neuroprotective effect of nepeta menthoides on the axotomized dorsal root ganglion sensory neurons in neonate r...

schizophrenia is a debilitating and pervasive mental illness with devastating effects on many aspects of psychological, cognitive and social wellbeing. epidemiological and life-cycle data point to significant differences in the incidence and course of schizophrenia between men and women, suggesting that estrogen plays a “protective” role . adjunctive estrogen therapy has been shown to be effect...

Secondary damage following primary spinal cord injury extends pathology beyond the site of initial trauma, and effective management is imperative for maximizing anatomical and functional recovery. Bisperoxovanadium compounds have proven neuroprotective effects in several central nervous system injury/disease models, however, no mechanism has been linked to such neuroprotection from bisperoxovan...

BACKGROUND AND PURPOSE Isoflurane, administered before or during cerebral ischemia, has been shown to exhibit neuroprotection in animal models of ischemic stroke. However, the underlying mechanism remains to be elucidated. In the present study, we determined whether isoflurane posttreatment provides neuroprotection after neonatal hypoxia-ischemia (HI) in rats and evaluated the role of the sphin...

Ischemic tolerance induced by hyperoxia (HO) can protect against brain injury and neurodegenerative diseases. Although multiple studies demonstrate neuroprotection by HO, the exact mechanism(s) of HO neuroprotection has not been elucidated. Here, I first review related mechanisms of brain ischemia and then data evaluating the neuroprotective effects of HO in focal and global ischemic animal mod...
