... on gamma-aminobutyric acid (GABA) release. Animals that survive anoxia must also tolerate reoxygenation – a major challenge that could cause a massive production of damaging reactive oxygen species (ROS). Here, the handling of succinate, which builds up during anoxia, is critical. Interestingly...

...John O. Onukwufor; Nicole MacDonald; Fred Kibenge; Don Stevens; Collins Kamunde The goal of the present study was to elucidate the modulatory effects of cadmium (Cd) on hypoxia/reoxygenation-induced mitochondrial dysfunction in light of the limited understanding of the mechanisms of multiple...

... species (ROS) upon reoxygenation. Crucian carp appear to exploit this mechanism by upregulating nitrite and other nitrite/NO metabolites ( S -nitroso and iron-nitrosyl compounds) in several tissues when exposed to anoxia. We investigated whether this is a common strategy amongst anoxia-tolerant...

.... Physiological levels of d -glucose did not influence twitch force development for aerobic preparations (1) paced at 0.5 or 1.1 Hz, (2) at 15 or 23°C, (3) receiving adrenergic stimulation or (4) during reoxygenation with or without adrenaline after severe hypoxia. Contractile responses to ryanodine, an inhibitor...

... was measured in heart and brain tissue from short-horned sculpin Myoxocephalus scorpius L. exposed to acute hypoxia and to graded hypoxia and reoxygenation at 8°C. Cardiorespiratory parameters were recorded along with plasma lactate, K + ,Ca 2+ and Na + levels and their relationship to adenosine levels...

... oxidative modification( Toien et al., 2001 ). Indeed,plasma ascorbate concentrations decline in parallel with peak oxygen consumption ( Toien et al.,2001 ), and brain ascorbate concentrations increase significantly towards the end of arousal ( Ma et al.,2004 ). Hypoxia-reoxygenation promotes neuronal...
