Oxidative stress, which is one of the main harmful mechanisms pathologies including ischemic stroke, contributes to both neurons and endothelial cell damages, leading vascular lesions. Although many antioxidants are tested in preclinical studies, no treatment currently available for stroke patients. Since cerium oxide nanoparticles (CNPs) exhibit remarkable antioxidant capacities, objective dev...

BACKGROUND AND PURPOSE Enhanced vascular permeability attributable to disruption of blood-brain barrier results in the development of cerebral edema after stroke. Using an in vitro model of the brain barrier composed of human brain microvascular endothelial cells and human astrocytes, this study explored whether small GTPase RhoA and its effector protein Rho kinase were involved in permeability...

Spinal cord injury (SCI) actuate to complex cellular and molecular interactions within the central nervous system in a heave to repair the initial tissue damage. The pathophysiology of acute spinal cord injury (SCI) involves primary and secondary mechanisms. Neuroinflammation is an important secondary injury process in SCI. The local inflammatory microenvironment within the injured spinal cord ...

The neuroprotective effects of progesterone after ischemic stroke have been established, but the role of progesterone in promoting cerebrovascular repair remains under-explored. Male Sprague-Dawley rats underwent transient middle cerebral artery occlusion (tMCAO) for 90 min followed by reperfusion for 3 days. Progesterone (8 mg/kg/day) was administered intraperitoneally at 1h after initial occl...

Accumulating evidence indicates that aldosterone plays a critical role in the mediation of oxidative stress and vascular damage. NADPH oxidase has been recognized as a major source of oxidative stress in vasculature. However, the relation between NADPH oxidase in aldosterone-mediated oxidative stress in endothelial cells remains to be ascertained. The present study aimed to investigate the rel...
