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,...

most common hypotheses of seizure initiation are increased neural excitation, decreased inhibition or both. but, the conditions that lead to these activation states not to be clear yet. recent studies challenge traditional concepts and indicate new evidence that a key epileptogenic process may actually begin in the blood vessel. seizures could be initiate by a variety of insults to the brain, s...

cell based therapeutics is one of the most rapidly advancing medical fields, bringing together a range of fields including transplantation, tissue engineering and regeneration, biomaterials and stem cell biology. however, traditional cell-based therapeutics have many limitations, one of which is their harmful effects exhibited on healthy body cells due to their lack of specificity. nanomedicine...

brain death is associated with increased inflammatory cytokines levels and poor graft quality to transplant. we aimed to evaluate the impact of ascorbic acid (aa) on the inflammatory status of brain-dead donors (bdds). forty bdds were randomly divided into two groups. donor treatment (n=20) consisted of 100 mg/kg aa infusion 6 hours before donor operation and subsequent infusion of 100 mg/kg/p6...

our goal in this paper is to describe and compare basic immunopathologic pattern of common demyelinating disorder, that is very important to choose the best treatment. The most common disorders are multiple sclerosis, neuromyelitis optica,Anti MOG associated disease,ADEM and autoimmune encephalitis. ADEM consists of ‘‘sleeves’’ of demyelination centered on small, engorge...

Introduction: It has been suggested physical exercise exerts neuroprotection in traumatic brain injury (TBI). However little information is available about the effect of endurance exercise on brain edema, inflammation and oxidant activity in diffuse TBI. Therefore, we investigated the prophylaxis effect of endurance training against oxidative damage, inflammation and brain edema assoc...

Traumatic brain injury (TBI) is a significant public health concern in our country, because of placing in top three most common causes of death and substantial direct and indirect costs to society. The incidence of TBI in our country is 1.7 times of international incidence. Traumatic brain injury induced by primary and secondary mechanisms that give rise to death and neurologic morbidity in pat...

Traumatic brain injury is considered as one of the main causes of morbidity and mortality worldwide. Apart from primary mechanical injury, Secondary injuries due to inflammation and apoptosis result in great neuronal damage. Current treatments are not able to regenerate the damaged part and prevent future sequels. Using human stem cells with self-assembling scaffolds may be promising in treatme...

Inflammation is a pathologic condition that includes a wide range of diseases namely neurodegenerative diseases. Several natural anti-inflammatory components have been identified in plant extracts used in traditional medicine for the relief of inflammation. Herbal medicine is showing difficulty in crossing the blood-brain barrier (BBB). So that the ability to pass the BBB is the main concern fo...
