Nucleoredoxin Plays a Key Role in the Maintenance of Retinal Pigmented Epithelium Differentiation

open access: yesAntioxidants, 2022
Nucleoredoxin (Nrx) belongs to the Thioredoxin protein family and functions in redox-mediated signal transduction. It contains the dithiol active site motif Cys-Pro-Pro-Cys and interacts and regulates different proteins in distinct cellular pathways. Nrx

Delayed cardioplegic reoxygenation reduces reoxygenation injury in cyanotic immature hearts

open access: yesThe Annals of Thoracic Surgery, 1998
Hypoxemic developing hearts are susceptible to oxygen-mediated damage that occurs after reintroduction of molecular oxygen. This unintended hypoxemic/reoxygenation injury leads to lipid peroxidation and membrane damage and may contribute to postoperative cardiac dysfunction.

The therapeutic effect of controlled reoxygenation on chronic hypoxia-associated brain injury

open access: yesBiology Open, 2019
Cardiopulmonary bypass (CPB) is the most general technique applied in congenital heart disease (CHD). However, standard CPB poses a specific pathologic condition for patients during surgery: exposure to reoxygenation.

Roles for Plant Mitochondrial Alternative Oxidase Under Normoxia, Hypoxia, and Reoxygenation Conditions

open access: yesFrontiers in Plant Science, 2020
Alternative oxidase (AOX) is a non-energy conserving terminal oxidase in the plant mitochondrial electron transport chain (ETC) that has a lower affinity for oxygen than does cytochrome (cyt) oxidase.

The effect of erythropoietin on calcium levels during hypoxia reoxygenation injury in rats

open access: yesGeriatric Care, 2016
This experimental study examined the effect of erythropoietin (Epo) on rat model and particularly in a hypoxia-reoxygenation protocol. The effect of that molecule was studied biochemically using blood mean calcium levels (Ca++). Forty rats of mean weight

Metabolomic and Lipidomic Analysis of the Colorectal Adenocarcinoma Cell Line HT29 in Hypoxia and Reoxygenation

open access: yesMetabolites, 2023
The poor availability of oxygen and nutrients in malignant tumors drives the activation of various molecular responses and metabolic reprogramming in cancer cells. Hypoxic tumor regions often exhibit resistance to chemotherapy and radiotherapy.

Myocardial Damage Induced by Uncontrolled Reoxygenation [PDF]

open access: yesAsian 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 ...

Glutathione Depletion Disrupts Redox Homeostasis in an Anoxia-Tolerant Invertebrate

open access: yesAntioxidants, 2023
The upregulation of endogenous antioxidants is a widespread phenomenon in animals that tolerate hypoxia/anoxia for extended periods. The identity of the mobilized antioxidant is often context-dependent and differs among species, tissues, and stresses ...
