Structural changes of eye chorioretinal complex were investigated in 40 adult male outbred albino rats after total transient cerebral ischemia using electron microscopy and morphometric analysis. Furthermore, the influence of a new sterically hindered phenolic antioxidant dibornol on these processes was estimated. Our studies demonstrated that total transient cerebral ischemia in rats resulted in the capillary thrombosis of the choriocapillary lamina of the uvea, structural disturbances of the blood-retinal barrier, degeneration of the retinal neurons and radial glia. Course administration of dibornol was shown to improve the microcirculation and to protect the retinal neuronal structures, pigment epithelium, and radial glia.

Oral nimodipine is the only drug approved in North America for patients with aneurysmal subarachnoid hemorrhage (aSAH). However, bioavailability is variable and frequently poor, leading to fluctuations in peak plasma concentrations that cause dose-limiting hypotension. Furthermore, administration is problematic in patients who cannot swallow.

Mitochondrial quality control is crucial for the homeostasis of the mitochondrial network. The balance between mitophagy and biogenesis is needed to reduce cerebral ischemia-induced cell death. Ischemic preconditioning (IPC) represents an adaptation mechanism of CNS that increases tolerance to lethal cerebral ischemia.

Background: Endothelial dysfunction and inflammation are linked to migraine, which may contribute to atherogenesis and increase the risk of ischemia. In migraineurs, preclinical vascular involvement manifested as compromised structural characteristics of vessel wall has not received enough attention or evaluation.
Objectives: To measure plasma pentraxin 3 as an indicator of endothelial dysfunction in migraine in comparison to controls and to examine its correlation with clinical characteristics, headache severity, and brain magnetic resonance imaging findings.

Background: Continuous electroacupuncture pre-conditioning (EPRC) and post-conditioning (EPOC) effectively improve motor dysfunction after acute cerebral ischemia, but they require multiple treatments. Recently, electroacupuncture per-conditioning (EPEC) has demonstrated neuroprotective effects, indicating that this single-session intervention has short-term efficacy.
Objective: To evaluate the effect of EPEC at Huantiao (GB30) on motor recovery in acute cerebral ischemia mice.
