Reactive oxygen and nitrogen species (RONS) are produced by several endogenous and
exogenous processes, and their negative effects are neutralized by antioxidant defenses …

Reactive oxygen species (ROS) initially considered as only damaging agents in living
organisms further were found to play positive roles also. This paper describes ROS …

DNA damage and DNA repair may mediate several cellular processes, like replication and

Of the four native nucleosides, 2′-deoxyguanosine (dGuo) is most easily oxidized. Two
lesions derived from dGuo are 8-oxo-7, 8-dihydro-2′-deoxyguanosine (8-oxodGuo) and 2 …

Abnormal spermatozoa frequently display typical features of oxidative stress, ie excessive
level of reactive oxygen species (ROS) and depleted antioxidant capacity. Moreover, it has …

In living organisms production of reactive oxygen species (ROS) is counterbalanced by their
elimination and/or prevention of formation which in concert can typically maintain a steady …
