miR‑128 is upregulated in epilepsy and promotes apoptosis through the SIRT1 cascade.

The present study aimed to examine the functional and molecular effects of miR‑128 in epilepsy, in order to investigate its potential protective mechanisms. Firstly, miR‑128 expression in rats with lithium chloride‑induced epilepsy was demonstrated to be increased compared with the control rats. Subsequently, results from an in vitro epilepsy model demonstrated that overexpression of miR‑128 promoted nerve cell apoptosis, increased the protein expression of tumor protein p53, BCL2 associated X (Bax) and Cytochrome c, and enhanced caspase‑3/9 activity, whereas it suppressed the protein expression of sirtuin 1 (SIRT1).

Prior transient ischemic attacks may have a neuroprotective effect in patients with ischemic stroke.

Introduction: Although functional recovery and survival after ischemic infarction seem to improve in patients with prior transient ischemic attack (TIA), little is known about the role of characteristics of prior TIA in subsequent cerebral infarction. Thus, the objective of this study was to explore how the characteristics of prior TIA have a neuroprotective effect on patients with ischemic stroke.

Material And Methods: A total of 221 patients admitted consecutively to a primary care center for first-ever ischemic stroke were divided into two groups on the basis of the presence or absence of prior TIAs.

(2R,3S)-Pinobanksin-3-cinnamate improves cognition and reduces oxidative stress in rats with vascular dementia.

This study investigated the neuroprotective effects of (2R,3S)-pinobanksin-3-cinnamate (PNC) in rats with occlusion-damaged bilateral common carotid arteries. Administration with PNC (5 and 10 mg/kg/day) for 5 weeks significantly improved the behavioral performance of rats with vascular dementia, as showed in the Morris water maze test by shortening the escape latency and latency of crossing, completing more platform crossings, as well as spending more time in the target zone. Further evaluations found that PNC could markedly decrease malondialdehyde levels, enhance superoxide dismutase activity and glutathione levels, and decrease the release of cytochrome c as well as the activities of caspases.
