Effects of Exercise Training on Anxious-Depressive-like Behavior in Alzheimer Rat.

Purpose: This study aimed to examine the effects of treadmill training on anxious-depressive-like behaviors of transgenic Alzheimer rats in the early stage of Alzheimer's disease (AD) and provided evidence of exercise in alleviating fear-avoidance behavior deficits.

Methods: Male 2-month-old TgF344-AD and wild-type rats were divided into wild-type (n = 9), AD (n = 8), and AD + treadmill exercise (Exe) groups (n = 12). After 8 months of exercise, the passive avoidance test, Barnes maze task, novel object recognition test, and object location test were used to measure learning and memory function.

Photobiomodulation Therapy Attenuates Hypoxic-Ischemic Injury in a Neonatal Rat Model.

Photobiomodulation (PBM) has been demonstrated as a neuroprotective strategy, but its effect on perinatal hypoxic-ischemic encephalopathy is still unknown. The current study was designed to shed light on the potential beneficial effect of PBM on neonatal brain injury induced by hypoxia ischemia (HI) in a rat model. Postnatal rats were subjected to hypoxic-ischemic insult, followed by a 7-day PBM treatment via a continuous wave diode laser with a wavelength of 808 nm.

Tert-butylhydroquinone post-treatment attenuates neonatal hypoxic-ischemic brain damage in rats.

Hypoxic-ischemic (HI) encephalopathy is a leading cause of dire mortality and morbidity in neonates. Unfortunately, no effective therapies have been developed as of yet. Oxidative stress plays a critical role in pathogenesis and progression of neonatal HI.
