An association between manganese superoxide dismutase polymorphism and outcome of chemotherapy in acute myeloid leukemia

Haematologica, 2006
Manganese superoxide dismutase (MnSOD) protects cells against oxidative stress by eliminating superoxides. Hypothetically, decreased MnSOD levels in cancer might lead to increased oxidative stress and, thus, to increased sensitivity of cells to ...

Spectrally Coordinated Plasmonic–Photothermal Photocatalysts for Mineralization of Mixed Indoor VOCs Under White LED Illumination

Advanced Materials, EarlyView.
A plasmonic–photothermal–photocatalytic hybrid comprising Cu(II)‐grafted TiO2, yolk–shell Au@SiO2, and reduced graphene oxide sheets (CuT/AuSi‐GS) harvests full‐spectrum white light‐emitting diode (LED) light via complementary photocatalytic oxidation, localized surface‐plasmon‐resonance‐induced electric‐field enhancement, and photothermal acceleration.

Antioxidants as supplements during drug-induced thrombocytopenia: a comparative analysis of Vanillic acid, L-carnitine and Caripill™ [PDF]

The Ukrainian Biochemical Journal
Drug-induced thrombocytopenia (DIT) is a disorder where platelet count declines as an adverse effect of therapeutic drugs. Plant extract of C. papaya Caripill™ is known to elevate platelet count under thrombocytopenic conditions.

Pivotal role of superoxides generated in the mitochondrial respiratory chain in peroxynitrite-dependent activation of phospholipase A2.

, 2002
Exposure of PC12 cells to reagent peroxynitrite promotes the release of arachidonic acid (AA) mediated by activation of phospholipase A(2) [Guidarelli, Palomba and Cantoni (2000) Br. J. Pharmacol. 129, 1539-1542].

Defect‐Driven Charge Separation in Ba‐Doped SrTiO3: Correlating Photoelectrochemical Performance With Dye‐Selective Photocatalysis

Advanced Materials Interfaces, EarlyView.
Ba‐doped SrTiO3 perovskites establish a direct correlation between photoelectrochemical activity and photocatalytic performance. Optimized Ba0.5Sr0.5TiO3 exhibits enhanced charge separation, photocurrent generation, and visible‐light‐driven dye degradation through defect‐induced oxygen vacancies and lattice distortion.

Superoxide and superoxide dismutase in red blood cells.

The St. Luke's Hospital gazette, 1976
In 1969 a previously obscure copper protein of red blood cells, erythrocuprein, was shown to catalyse the dismutation of superoxide radicals. Erythrocuprein thus became superoxide dismutase and the object of intensive study. Superoxide dismutase is typically an enzyme of aerobic organisms which utilize oxygen as the major electron acceptor.
