BACKGROUND AND PURPOSE Cerebral hypoxic ischemia (HI) is an important cause of brain injury in the newborn infant. Adenosine is believed to protect against HI brain damage. However, the roles of the different adenosine receptors are unclear, particularly in young animals. We examined the role of adenosine A2A receptors (A2AR) using 7-day-old A2A knockout (A2AR(-/-)) mice in a model of HI. MET...

The aging brain is often characterized by the presence of multiple comorbidities resulting in synergistic damaging effects in the brain as demonstrated through the interaction of Alzheimer's disease (AD) and stroke. Gangliosides, a family of membrane lipids enriched in the central nervous system, may have a mechanistic role in mediating the brain's response to injury as their expression is alte...

main goal in the management of patients with severe traumatic brain injury (tbi) is control of intracranial pressure (icp). decompressive craniectomy is an accepted technique for control of refractory intracranial hypertension in patients with severe tbi. because of high complication rate after decompressive craniectomy, new techniques such as basal cisternostomy have developed. we herein repor...

conclusions a long-term longitudinal study encompassing integrated research is needed to fully understand the traumatic experiences of caregivers. unless research on tbi or dai trauma is given its proper attention, the burden of trauma and injury on societies will continue to exacerbate globally. context as with care giving and rehabilitation in chronic illnesses, the concern with traumatic bra...

the serotonin (5-ht) receptors are a group of g protein-coupled receptors (gpcrs) and ligand-gated ion channels that found in the central and peripheral nervous systems. 5ht receptor can substantially influence brain functions such as learning and memory, perception of the environment, mood states, and responses to alcohol and other drugs of abuse. lysergic acid diethylamide (lsd) as a 5ht rece...

conclusions although ceiling effects should be considered for rehabilitation targets, the two-factor model of fim (motor and cognitive independence) has an eligible fitness for iranian patients with tbi. results the results of this study showed that the floor effect was not observed; however, ceiling effects were observed for the fim total score and its subscales. the confirmatory factor analys...

BACKGROUND We examined the influence of low-dose alcohol consumption on cerebral ischemia/reperfusion (I/R) injury in mice and a potential mechanism underlying the neuroprotective effect of low-dose alcohol consumption. METHODOLOGY/PRINCIPAL FINDINGS C57BL/6 J mice were fed a liquid diet without or with 1% alcohol for 8 weeks, orally treated with rosiglitazone (20 mg/kg/day), a peroxisome pro...

BACKGROUND Unilateral spatial inattention (USI) (a.k.a. neglect, unilateral neglect, visual neglect) is a common occurrence after stroke. It can also occur subsequent to traumatic brain injury. Insult to the right inferior (posterior) parietal cortex is the structure that is virtually always involved, although other brain areas have been implicated. The major consequence of USI is that the pati...

We used positron emission tomography in healthy volunteers to test hemispheric rivalry theories for normal and pathological spatial attention, which provide an influential account of contralesional extinction on bilateral stimulation after unilateral brain injury. Subjects reported visual characters presented either unilaterally or bilaterally. An extinction-like pattern was found behaviorally,...

Polydatin is a key component of Polygonum cuspidatum, a herb with medical and nutritional value. The present study investigated the protective effect of polydatin against learning and memory impairment in neonatal rats with hypoxic-ischemic brain injury (HIBI). The unilateral common carotid artery ligation method was used to generate neonatal HIBI rats. Y-maze testing revealed that rats with HI...
