The molecular mechanism underlying the role of hippocampal hilar interneuron degeneration in temporal lobe epilepsy (TLE) remains unclear. Especially, very few studies have focused on the role of neuronal nitric oxide synthase (nNOS, encoded by Nos1) containing hilar interneurons in TLE. In the present study, Nos1 conditional knockout mice were constructed, and we found that selective deletion of Nos1 in hilar interneurons rather than dentate granular cells (DGCs) triggered epileptogenesis.

However, current analgesics and antidepressants exhibit limited efficacy for this comorbidity. The present study aimed to investigate the effect of ketamine on the comorbidity of inflammatory pain and consequent depression-like behaviors in a rat model established by intraplantar administration of complete Freunds adjuvant (CFA).

Tert-butylhydroquinone (tBHQ), a commonly used nuclear factor erythroid 2-related factor 2 (Nrf2) activator, was found to significantly enhance autophagy activation. The aim of this study was to explore the effect of tBHQ treatment on early stage brain injury at 24 h after SAH.

Hydrocephalus can lead to high intracranial pressure, which in turn results in disturbance of consciousness, cerebral hernia, and even death. Hydrocephalus management is important in the treatment of pineal region tumors.

However, the underlying mechanisms are poorly understood. Here we assessed the effect of zinc on ubiquitin conjugation and subsequent neurodegeration following traumatic brain injury (TBI).

The expression pattern of PGC-1α after traumatic brain injury (TBI) has not been studied.
Materials And Methods: Ninety male ICR mice (28-32 g) were randomly assigned to six groups: sham, 3, 6, 12, 24 and 48 hours after TBI.
