Drosophila were examined to see if there is an increase in damage associated with free radical activity in older flies. The levels of superoxide radical and of lipid peroxides were higher in membrane samples from older flies. Also, in older Drosophila there was a significant decrease in membrane fluidity, as determined by fluorescence polarization, and an(More)
Previously our study has demonstrated that long-term treadmill exercise improved cognitive deficit in APP/PS1 transgenic mice of Alzheimer's disease (AD) paralleled by enhanced long-term potentiation (LTP). The present study was undertaken to further investigate whether the treadmill running could inhibit the progression of Alzheimer's disease (AD)-like(More)
Alzheimer's disease (AD) is a progressive neurodegenerative disease clinically characterized by learning and memory function deterioration. While it is well established that exercise can improve cognitive performance in AD, there have been few basic cellular and molecular mechanisms research performed to test the interaction between exercise and AD. In this(More)
OBJECTIVE To estimate the effect of aluminum on hippocampal intracellular Ca²+ concentration and expression of phospholipase C (PLC) and NMDA receptor α (NMDARα) genes in hippocampus as well as the neural behaviors in weaning rats through subchronic exposure in order to explore the mechanism which aluminum impaired the ability of learning and memory of(More)
