Haseki Tıp Bülteni, 2016 Aim: This biomedical study tested the effect of erythropoietin (Epo) in rat model, especially in a hypoxia-reoxygenation one. The trend of this factor was evaluated hematologically using serum mean platelets volume (MPV) values. Methods: Forty rats with

Myocardial Damage Induced by Uncontrolled Reoxygenation [PDF]
Asian Cardiovascular and Thoracic Annals, 2000 To evaluate myocardial impairment induced by uncontrolled reoxygenation, the effects of hypoxia-reoxygenation were compared with ischemia-reperfusion in isolated rat hearts. After stabilization, 2 groups (n = 8) of Langendorff-perfused rat hearts were exposed to 40 minutes of ischemia (10% of baseline flow) or hypoxia (10% of ...

The Contribution of Reoxygenation to Ischemic Brain Damage [PDF]
Journal of Cerebral Blood Flow & Metabolism, 1991 This study examined the hypothesis that the level of postischemic reperfusion affects the severity of the resulting neuronal necrosis. In rats, tissue Po 2 % was monitored as an index of flow (reoxygenation) at four cortical sites by chronically implanted platinum electrodes.

Studies of hypoxemic/reoxygenation injury: without aortic clamping. II. Evidence for reoxygenation damage. [PDF]
The Journal of thoracic and cardiovascular surgery, 1995 This study tested the hypothesis that the developing heart is susceptible to oxygen-mediated damage after reintroduction of molecular oxygen and that this "unintended" reoxygenation injury causes lipid peroxidation and functional depression that may contribute to perioperative cardiac dysfunction.

Studies of hypoxemic/reoxygenation injury: with aortic clamping. XII. Delay of cardiac reoxygenation damage in the presence of cyanosis: a new concept of controlled cardiac reoxygenation. [PDF]
The Journal of thoracic and cardiovascular surgery, 1995 Twenty-one immature piglets (< 3 weeks old) underwent 30 minutes of aortic clamping with hypocalcemic glutamate/aspartate blood cardioplegia. Six piglets underwent hyperoxemic cardiopulmonary bypass and blood cardioplegia without preceding hypoxemia (control).

Stresses, 2023 Hypoxic stress, caused by the low cellular oxygen in the events of flooding or waterlogging, limits crop productivity in many regions of the world. Hypoxic stress in plants is often dynamic and followed by a reoxygenation process that returns the oxygen ...

Down-regulation of NDRG1 promotes migration of cancer cells during reoxygenation.
PLoS ONE, 2011 One characteristic of tumor microenvironment is oxygen fluctuation, which results from hyper-proliferation and abnormal metabolism of tumor cells as well as disorganized neo-vasculature. Reoxygenation of tumors can induce oxidative stress, which leads to

Novel Targets in a High-Altitude Pulmonary Hypertension Rat Model Based on RNA-seq and Proteomics
Frontiers in Medicine, 2021 High-altitude pulmonary hypertension (HAPH) is a complication arising from an inability to acclimatize to high altitude and is associated with high morbidity and mortality.
