Neural stem cells hold the key to innovative new treatments for age-associated degeneration and traumatic injury to the brain and spinal cord. We hypothesized that the in vivo induced pluripotent stem cells or neural stem cells through "forced gene expression" can be used to repair damaged brain areas or treat degenerative diseases. Hopefully, these in vivo patient-specific stem cells can bring...

intracranial hypertension is the largest cause of death in young patients with severe traumatic brain injury. decompressive craniectomy is part of the second level measures for the management of increased intracranial pressure refractory to medical management as moderate hypothermia and barbiturate coma. the literature lack of concepts is their indications. we present a review on the state of t...

cortical spreading depression (csd) are associated with dramatic failure of brain ion homeostasis, efflux of excitatory amino acids from nerve cells, increased energy metabolism and changes in cerebral blood flow. there is strong clinical and experimental evidence to suggest that csd is involved in the mechanism of migraine, stroke, subarachnoid hemorrhage and traumatic brain injury. therefore,...

continuous four hours eeg (electroencephalogram) recordings and its power spectrum analysis using fast fourier transform (fft) in urethane anesthetized male charles foster rats were performed in two groups: open brain injury and p-cpa (para-chlorophenylalanine) pretreated before brain injury, respectively, and compared with the eeg power spectrum of control rats. the eeg power spectrum analysis...

objective(s): preclinical studies show that iron plays a key role in mediating neuronal injury. this study was performedin order to identify the relationship between the serum level of ferritin and severity of the brain injury which occur after an intracerebral hemorrhage (ich). materials and methods:this was a cross sectional descriptive – analytic study, which was conducted on those patients ...

objective(s):this study was carried out to investigate the effects of cox-2 selective inhibitor (celecoxib) or non-selective cox inhibitor (ibuprofen) on gastrointestinal motility. materials and methods: the rats were randomly divided into five groups including: intact, sham, traumatic brain injury (tbi) group (intact rats under tbi), celecoxib group (10 mg/kg), ibuprofen group (10 mg/kg). rats...

background variables derived from electroencephalogram like cerebral state index (csi) have been used to monitor the anesthesia depth during general anesthesia. observed evidences show such variables have also been used as a detector of brain death or outcome predictor in traumatic brain-injured (tbi) patients. objectives the current study was designed to determine the correlation between glasg...

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 ...

Reactive astrogliosis is the process by which astrocytes respond to central nervous system injury or disease. The origin of these cells is under debate. Herein, we contribute to comments regarding our recent report and discuss the context of our findings. One of the main goals in the field of neuroscience is to understand the cellular basis and molecular pathways that underlie injury and diseas...

introduction: following a traumatic brain injury (tbi), the excessive release of proinflammatory cytokines is major cause of cerebral edema that can cause permanent neuronal loss. this study examined the changes in brain concentrations of proinflammatory cytokines il-1, il-6, tnf-α and tgf- after different doses of estrogen or progesterone treatment in brain-injured rats at 6 and 24 h post-in...
