Anoxia-reoxygenation versus ischemia in isolated rat lungs

, 1997
Oxidant generation in anoxia-reoxygenation and ischemia-reperfusion was compared in isolated rat lungs. Anoxia-reoxygenation was produced by N2 ventilation followed by O2 ventilation. After anoxia, lung ATP content was decreased by 59%.

Protection from reoxygenation injury by inhibition of rac1.

, 1998
We demonstrate that adenoviral-mediated gene transfer of a dominant negative rac1 gene product (N17rac1) inhibits the intracellular burst of reactive oxygen species (ROS) that occurs after reoxygenation of vascular smooth muscle cells.

Reoxygenation after severe hypoxia induces cardiomyocyte hypertrophy in vitro: activation of CREB downstream of GSK3beta

, 2004
In vivo, left ventricular remodeling after myocardial infarction involves hypertrophy generally attributed to increased cardiac workload. We hypothesized that hypoxia/reoxygenation directly induces cardiomyocyte hypertrophy and studied several ...

Phosphoproteomic changes in response to anoxia are tissue-specific in the anoxia-tolerant crucian carp (Carassius carassius)

Frontiers in Physiology
Crucian carp (Carassius carassius), a freshwater fish, can survive chronic anoxia for several months at low temperatures. Consequently, anoxia-related physiological and biochemical adaptations in this species have been studied for more than half a ...

Effects of hypoxia and reoxygenation on arterial blood parameters.

, 2018
Values are given for baseline (min 0), during hypoxia (min 2 to min 14) and during reoxygenation (min 15 to min 23) in controls (blue) and after α1A-adrenergic blockade (red) for (A) pH, (B) partial pressure of carbon dioxide (pCO2), (C) partial pressure

Hypoxia-reoxygenation impairs endothelium-dependent relaxation in isolated rat aorta

, 1996
The effects of hypoxia followed by reoxygenation on endothelium-dependent relaxation in isolated rat aorta were investigated. Acetylcholine (ACh, 3 nM-10 microM) and calcium ionophore A-23187 (3 nM-300 nM)-induced endothelium-dependent vasorelaxation of

Hypoxic preconditioning reduces reoxygenation injuries via PI3K in respiratory muscle

, 2014
Reperfusion of hypoxic skeletal muscle adversely affects muscle function. Currently, there is no effective method to prevent this damage. In heart research, these injuries may be attenuated by preconditioning treatment.

Exposure to high altitude leads to disturbances in host metabolic homeostasis: study of the effects of hypoxia-reoxygenation and the associations between the microbiome and metabolome

mSystems
This study investigated alterations in hematological parameters, gut microbiota composition, and fecal and plasma metabolic profiles among high-altitude residents during reoxygenation periods of 1 week, 1 month, and 4 months to elucidate the effects of ...
