Cerebral ischemia is a leading cause of ischemic stroke, which may lead to severe disability and mortality worldwide. There are some key factors concerned in cardioprotection, such as peroxisome proliferator‑activated receptor γ (PPARγ), a ligand binding transcription factor involved in various biological functions including atherosclerosis, vascular dysfunction and hypertension, and baculovira...

Traumatic brain injury (TBI) leads to important and deleterious neuroinflammation, as evidenced by indicators such as edema, cytokine production, induction of nitric oxide synthase, and leukocyte infiltration. After TBI, cerebral vascular endothelial cells play a crucial role in the pathogenesis of inflammation. In our previous study, we proved that simvastatin could attenuate cerebral vascular...

BACKGROUND AND PURPOSE Therapeutic angiogenesis aims at improving cerebral blood flow by amplification of vascular sprouting, thus promoting tissue survival under conditions of subsequent ischemia. It remains unknown whether induced angiogenesis leads to the formation of functional vessels that indeed result in hemodynamic improvements. Observations of hemodynamic steal phenomena and disturbed ...

An 87-year-old woman presented with a 3-month history of fever, edema of the lower legs, and gait disturbance. A laboratory examination revealed high serum levels of myeloperoxidase-specific antineutrophil cytoplasmic antibody (MPO-ANCA). Although microscopic polyangiitis was initially suspected and treated, the patient subsequently developed transient hemiparesis and disturbed consciousness. B...

Physical exercise is any bodily activity to enhance or maintain physical fitness and overall health and wellness. A series of associated studies have demonstrated that physical exercise could alleviate the infarct volume, increase the collateral circulation, promote endothelial progenitor cells, improve cerebral blood flow after cardiovascular and cerebrovascular diseases. In this review, we su...

Hydroperoxide-induced oxidative stress is assumed to be involved in vasospasm of cerebral arteries after subarachnoid hemorrhage. In order to study underlying mechanisms the effects of H2O2 and tert butylhydroperoxide on contractile functions as well as on free radical production of anterior cerebral artery from pig were investigated. The hydroperoxides increased in a similar dose-dependent art...

KCNK2 was previously shown to regulate immune-cell trafficking into the central nervous system (CNS). Kcnk2-/- mice demonstrated a more severe disease course in experimental autoimmune encephalomyelitis, an animal model of multiple sclerosis, due to an increased immune-cell migration into the CNS. An upregulation of the cellular adhesion molecules ICAM1 and VCAM1 on brain endothelial cells in K...

PURPOSE To determine the appropriate concentration of papaverine for therapeutic intraarterial infusion against cerebral vasospasm. METHODS We investigated histopathologic changes in cerebral arteries and brain tissue of normal Wistar rats that had received infusions of papaverine via the carotid artery. Rats were infused with 0.20 mL papaverine (concentration, 0.4% to 4.0%) via the internal ...

Fifteenth of Cronobacter sakazakii were obtained from previous studies isolates (infant formula, spinal fluid and bloods). The newborn mice number was 15 obtaining healthy the Iraqi Center for Cancer Medical Genetics whose ages ranged between 10-17 days their weights 8.5 ± 1.25 gm, divided into 3 groups. samples cut placed in formalin, then stabilizer concentrations alcohol (70%, 80%, 90%,100%)...

The adhesion of infected red blood cells (iRBCs) to human endothelium is considered a key event in the pathogenesis of cerebral malaria and other life-threatening complications caused by the most prevalent malaria parasite Plasmodium falciparum. In the past 30 years, 14 endothelial receptors for iRBCs have been identified. Exposing 10 additional surface proteins of endothelial cells to a mixtur...
