Antioxidants, Volume 6, Issue 1

2017 March - 21 articles

Cover Story: Oxidative stress is an overabundance of free radicals compared to reducing agents and has been associated with a number of chronic diseases. While blood is the conventional biospecimen for examining oxidative stress, a noninvasive approach would be efficacious towards diagnosing pathogenetic conditions that burden the public. Saliva is a fluid found within the mouth and is a readily available biospecimen that can be utilized without rigorous training for collection. Reducing agents, such as vitamin C, and oxidized compounds, such as malondialdehyde, that reflect health can be measured in saliva, suggesting the potential of oral fluid for the analysis of oxidative stress and overall wellness.
