The spin trap 5,5-dimethyl-1-pyrroline-1-oxide (DMPO) alone, as well as DMPO or N-tert-butyl-alpha-phenylnitrone (PBN) in the presence of excess dimethyl sulfoxide (Me2SO), have been used as spin trapping systems for the detection of hydroxyl radical. However, the instability of DMPO and

Sulfur and nitrogen co-doped reduced graphene oxide (rGO) is synthesized by a facile method and demonstrated remarkably enhanced activities in metal-free activation of peroxymonosulfate (PMS) for catalytic oxidation of phenol. Based on first-order kinetic model, S-N co-doped rGO (SNG) presents

We compared oxygenation and anaerobic oxidation reactions of a purified complex of human hemoglobin (Hb) and haptoglobin (Hb-Hp) to those of uncomplexed Hb. Under equilibrium conditions, Hb-Hp exhibited active-site heterogeneity and noncooperative, high-affinity O(2) binding (n(1/2)=0.88, P(1/2)=0.33 mm Hg in

Complex I is a critical site of O(2)(•-) production and the major host of reactive protein thiols in mitochondria. In response to oxidative stress, complex I protein thiols at the 51- and 75-kDa subunits are reversibly S-glutathionylated. The mechanism of
