The beneficial effect of the flavonoid quercetin on behavioral changes in hemi-Parkinsonian rats
Introduction: A large body of experimental evidence supports a role for oxidative stress as a mediator of nerve cell death in Parkinson's disease (PD). Flavonoids like quercetin have been reported to prevent neuronal degeneration caused by increased oxidative burden, therefore, this st...
