Age and sex-related changes in superoxide dismutase activity in bovine tissues
antioxidative enzymes cows calves bulls age sex
2015/9/15
The influence of age, gender, and type of tissue on superoxide dismutase (SOD) activity in bovine organs and tissues was investigated. The investigated material consisted of fragments of tissues and o...
Mycobacterial catalases, peroxidases, and superoxide dismutases and their effects on virulence and isoniazid-susceptibility in mycobacteria – a review
tuberculosis antituberculotic drugs Mycobacterium tuberculosis
2015/2/5
Mycobacteria are intracellular bacterial parasites which survive and proliferate inside of macrophages for long periods of time. Because mycobacterial survival in macrophages is required for virulence...
Characterization of superoxide dismutase in the rumen bacteriumStreptococcus bovis
Streptococcus bovis paraquat superoxide dismutase glutathione peroxidase
2015/1/26
Superoxide dismutase (SOD) isoenzymes of the rumen bacterium Streptococcus bovis 4/1 were studied. Native PAGE showed a single band of Mn-SOD, unaffected by 10 mM cyanide or 5 mM hydrogen peroxide und...
Rac Activation Induces NADPH Oxidase Activity in Transgenic COSphox Cells and Level of Superoxide Production is Exchange Factor-Dependent
NADPH oxidase Rac
2014/12/12
Transient expression of constitutively active Rac1 derivatives, (G12V) or (Q61L), was sufficient to induce phagocyte NADPH oxidase activity in a COS-7 cell model in which human cDNAs for essential oxi...
Antioxidant activity coefficient, mechanism, and kinetics of different derivatives of flavones and flavanones towards superoxide radical
antioxidant activity coefficient flavonoids binding constant homogeneous kinetics cyclic voltammetry
2014/2/25
A systematic investigation of the electrochemically generated superoxide radical (O2●–) has been conducted in the presence of some flavonoids. Cyclic voltammetry was used to generate O2●– by reducing ...
Cloning, Expression, Characterization, and Computational Approach for Cross-Reactivity Prediction of Manganese Superoxide Dismutase Allergen from Pistachio Nut
cloning cross-reaction Manganese Superoxide Dismutase (MnSOD) pistachio (Pistacia vera)
2010/11/12
The MnSOD gene from pistachio was successfully cloned and expressed in E. coli. The purified pistachio MnSOD was recognized by IgE in 10 (40%) out of the 25 sera tested. Our results also showed that t...
Dynamics of nonphotochemical superoxide production in the Great Barrier Reef lagoon
Dynamics of nonphotochemical superoxide production the Great Barrier Reef lagoon
2014/4/17
Superoxide (O2-) and hydrogen peroxide (H2O2) concentrations ranging from 87 to 1120 pmol L-1 and 5 to 107 nmol L-1, respectively, were measured in samples of surface water from the Great Barrier Reef...
Application of an Oxygen Electrode to Evaluate Superoxide Anion-scavenging Ability
Application Oxygen Electrode Evaluate Superoxide Anion-scavenging Ability
2010/9/15
The ability to scavenge superoxide anion radicals (•O2−) was determined using an oxygen electrode. The method is based on the determination of •O2− generated by the reaction of...
