Many therapies with potential for treatment of brain injury have been investigated. Few types of cells have spurred as much interest and excitement as stem cells over the past few decades. The multipotentiality and self-renewing characteristics of stem cells confer upon them the capability to regenerate lost tissue in ischemic or degenerative conditions as well as trauma. While stem cells have ...

The discovery in the year 2000 that radial glial cells act as neural stem and progenitor cells in development has led to a change in the concept of neural stem cells in the adult brain. Not only are adult stem cells in the neurogenic niches glial in nature, but also glial cells outside these niches display greater potential when reacting to brain injury. Thus, a concept that emerged from develo...

objective(s) gastric ulceration is induced by various forms of stress like surgery, ischemia and trauma. the female sex has more resistance to stress and the gastrointestinal lesions happen fewer than male sex. the purpose of this study was to evaluate the role of estradiol and progesterone on the gastric acid and pepsin levels following traumatic brain injury (tbi) induction. materials and met...

in western countries such as united states data from 2002-2006 showed that at least 1.7 million people sustain a traumatic brain injury (tbi) each year. of those individuals, about 52,000 die, 275,000 are hospitalized, and 1.365 million are treated and released from an emergency department. in 2000, direct medical costs and indirect costs such as lost productivity of totaled an estimated $76.5 ...

traumatic brain injury (tbi) is one of the serious neurodisorders commonly caused by car accidents and sports. preventive measures are highly recommended to reduce the risk and number of tbi cases. after tbi, the primary injury to the brain initiates a secondary injury process that spreads via multiple molecular mechanisms in the pathogenesis of tbi. many studies in animals using cdna microarra...

background neurosurgical treatment and the severity of head injury (hi) can have remarkable effect on patients’ neuropsychiatric outcomes. objectives this research aimed to study the effect of these factors on cognitive functioning, general health and incidence of mental disorders in patients with a traumatic brain injury (tbi). patients and methods in this descriptive, longitudinal study, 206 ...

When brain injury is refractory to aggressive management and is considered nonsurvivable, with loss of consciousness and brain stem reflexes, a brain death protocol may be initiated to determine death according to neurological criteria. Clinical evaluation typically entails 2 consecutive formal neurological examinations to document total loss of consciousness and absence of brain stem reflexes ...

Stem cell studies are being currently widely used in neuroscience particularly for degenerative, developmental, and neoplastic disorders in addition to trauma. Laboratory studies of recurrent glioblastoma multiforme (GBM) stem cell vaccinations have already been completed and a Phase I safety study in human volunteers with recurrent GBM is in progress (1). Findings derived from animal studies w...
