Australian research conducted in 2009 by subjecting in vitro samples of human spermatozoa to radio-frequency radiation at 1.8 GHz and specific absorption rates (SAR) of 0.4 to 27.5 W/kg showed a correlation between increasing SAR and decreased motility and vitality in sperm, increased oxidative stress and 8-Oxo-2'-deoxyguanosine markers, stimulating DNA base adduct formation and increased DNA fragmentation.
He was first to work on nicotine and its effect on oxidative stress in Bidi (Hand rolled cigarette in Tendu leaves) workers.
Adaptogenic effect of some herbs may hold certain merit on account of the ability of the substances to increase the bodies own response to oxidative stress, such as gynostemma pentaphyllum or poor-man's ginseng, which has been shown to increase the body's innate response by increased production of superoxide dismutase (SOD).
The studies are the first to show that oxidative stress that would otherwise trigger or enhance Aspergillus flavus aflatoxin production can be stymied by caffeic acid.
