Methods: Forty rats were divided into five groups: sham-control, TBD, TBD + phloretin (80 mg/kg/dose intraperitoneally at 30 minutes and on days 2/3 post-TBD), TBD + hPRP (80μL by left intra-carotid-artery injection at 3 hours post-TBD), and TBD + phloretin + hPRP. Cerebral tissues were harvested on day 28 post-TBD for analysis.

Results: Brain MRI on day 28 showed the lowest BHV in the sham-control group and the highest in the TBD group.

Melatonin rescues cerebral ischemic events through upregulated tunneling nanotube-mediated mitochondrial transfer and downregulated mitochondrial oxidative stress in rat brain.

Background: Cerebral ischemic events, comprising of excitotoxicity, reactive oxygen production, and inflammation, adversely impact the metabolic-redox circuit in highly active neuronal metabolic profile which maintains energy-dependent brain activities.
