... superoxide dismutase (SOD) activity, in Atlantic salmon acclimated at 12°C and 20°C The integrity of the mitochondrial outer membrane was altered by test temperature (two-way ANOVA, F =9.137, P =0.0116), but not by acclimation temperature (two-way ANOVA, F =0.4310, P =0.5250). For example...

... was accompanied by a significant increase in superoxide dismutase (SOD) and catalase (CAT) activity as a consequence of induction of corresponding genes. HEA exposure also led to the stimulation of NO production due to induction of inducible nitric oxide synthase (iNOS) activity, as a consequence of up-regulation...

...) composition between groups. Hypoxia acclimation did not alter mitochondrial coupled or uncoupled respiration, or respiratory control ratio, ROS release rates, P 50 or superoxide dismutase activity. However, it increased citrate synthase activity (by ∼20%), increased the sensitivity of mitochondrial...

... and Ṗ CO 2 have on the level of protein damage in Trematomus bernacchii, Pagothenia borchgrevinki and Trematomus newnesi , and combined these measurements with changes in total enzymatic activity of catalase (CAT) and superoxide dismutase (SOD) in order to gauge tissue-specific changes in antioxidant...

...A. M. Tarrant; A. M. Reitzel; C. K. Kwok; M. J. Jenny Organisms are continuously exposed to reactive chemicals capable of causing oxidative stress and cellular damage. Antioxidant enzymes, such as superoxide dismutases (SODs) and catalases, are present in both prokaryotes and eukaryotes and provide...

These results strongly suggest that the larval construction behaviour triggered the production...

By contrast, the activities ( V max )of enzymes involved in aerobic performance, phosphofructokinase, hexokinase,pyruvate kinase and cytochrome c oxidase, did not increase in the flight muscles of hive bees, young foragers, mature...

...Adam P. Starrs; Sandra Orgeig; Christopher B. Daniels; Margaret Davies; Olga V. Lopatko SUMMARY The activities of the pulmonary antioxidant enzymes (AOE), superoxide dismutase (SOD), glutathione peroxidase (GPx) and catalase, increase in the final 10–20 % of gestation in the mammalian lung...

... and the physico-chemical conditions of this dark, poorly oxygenated environment, the meso- and bathypelagic waters of the oceans might be considered as refuges against oxidative dangers. This hypothesis prompted us to investigate the activities of the three essential enzymes (superoxide dismutase, SOD; catalase...

...Irwin Fridovich ABSTRACT During its reduction to water, O 2 readily gives rise to dangerously reactive intermediates. This threat is diminished by families of defensive enzymes which include the superoxide dismutases, catalases and peroxidases. Free radical chain reactions are controlled...
