...Brittney G. Borowiec; Graham R. Scott ABSTRACT Hypoxia is common in aquatic environments, and exposure to hypoxia followed by re-oxygenation is often believed to induce oxidative stress. However, there have been relatively few studies of reactive oxygen species (ROS) homeostasis and oxidative...

... ) by examining covariation in VTG with the ovarian cycle, and relative to reactive oxygen species (ROS) including baseline superoxide (bSO). Plasma VTG decreased prior to ovulation, when VTG is deposited into follicles. VTG, however, remained elevated post-ovulation when no longer necessary for yolk provisioning...

...Gigi Y. Lau; Jeffrey G. Richards ABSTRACT Environmental hypoxia presents a metabolic challenge for animals because it inhibits mitochondrial respiration and can lead to the generation of reactive oxygen species (ROS). We investigated the interplay between O 2 use for aerobic respiration and ROS...

... was enhanced by high-salt exposure in YSM tissue. Moreover, the reduction in expression of HIF2 and FGF2 genes might cause high-salt-suppressed angiogenesis. Interestingly, we show that high-salt exposure causes excess generation of reactive oxygen species (ROS) in the heart and YSM tissues, which could...

... species (ROS) in disused muscles may lead to oxidative stress, which in turn is associated with increased atrophic or apoptotic signalling and/or oxidative damage to the muscle and thus muscle disuse atrophy. Increases in the rate of oxygen consumption likely increase the overall generation of ROS in vivo...

... oxidation of lipids `lipidperoxidation' commences with lipid radical production and leads to the accumulation of stable degradation products, such as malondialdehyde ( Sies,1986 ). During exercise elevated metabolic rates can lead to higher ROS generation and thus higher lipidperoxidation. However...

.../recovery. Our data suggest that p38 MAPK inhibits ERK activity at the level of MEK during chemical anoxia. During recovery, we demonstrated the requirement for ROS, produced via a NAD(P)H oxidase-like activity for reactivation of ERK in a Raf-independent manner. We speculate that ROS results...
