and developed by Ames et al. (5) three decades ago. In vitro experiments showed that UA is a potent scavenger of singlet oxygen, peroxyl radicals (RO∘22°), and hydroxyl radicals (5). It also protects the cell from oxidative damage by...

metal chelating property of DMSA is due to the presence of vicinal dithiol groups that may also act as an oxygen radical scavenger and thus inhibit lipid peroxidation, giving an added advantage of fighting heavy metal induced oxidative...

in (or near) mitochondria [42]. We have explored the possibility that PA could serve as a free radical scavenger. ORAC (oxygen radical absorbance capacity), TEAC (trolox equivalent antioxidant capacity), and hydrogen peroxide AOC assays...

normal oxygen metabolism or are induced by exogenous damage [122]. Eventually, these excess ROS can produce unadorned oxidative stress to the bacterial cell membrane leads to increased permeability, nucleic acid damage and oxidation of...

of oxygen. Similarly in the gut, indole pyruvate generated by transamination of tryptophan may thus be applied as electron acceptor and reduced to ILA by action of the ILA dehydrogenase (Fig. 2). Such fine-tuning reactions might thus...

reactive oxygen species (ROS)/reactive nitrogen species (RNS) generation. Free radical-mediated oxidative stress, together with apoptosis, is often activated in tumor cells by melatonin [76]. Given that melatonin is present perhaps in...
