Context: Cell death and inflammation response have been found to the primary features of acute kidney injury. Objective: The aim of our study is to figure out the molecular mechanism by which hypoxia-reoxygenation injury affects the viability of tubular ...

Tissue changes consistent with oxidative damage in hypoxic/reoxygenated heart tissue have not been well documented. We recently reported that oxidative perturbations were evident in isolated-perfused rat heart tissue subjected to as little as 10 min hypoxia and that these changes were not exacerbated by reoxygenation.

Hypoxia/Reoxygenation Affects Endotoxin Tolerance
Journal of Surgical Research, 1995Pretreatment of animals with sublethal doses of endotoxin renders them tolerant to subsequent endotoxin challenge. Tissue hypoxia following infection may potentiate the immune response to injury. To evaluate the effect of hypoxia/reoxygenation (H/R) on endotoxin tolerance by macrophages, adult CBA mice were pretreated with 10 micrograms/animal of LPS ...

Hypoxia is as an endocrine disruptor, and, in crustaceans, the energy metabolic consequences of hypoxia in the brain tissue are still poorly understood.

Reoxygenation and rehypoxiation in the SCCVII mouse tumor
International Journal of Radiation Oncology*Biology*Physics, 1994To test the hypothesis that, following preferential killing of tumor hypoxic cells, the fraction of hypoxic cells in the tumor will reestablish itself to pretreatment levels (rehypoxiation) with the same kinetics as for reoxygenation.Mouse squamous cell carcinoma VII (SCCVII) tumors were treated with a single dose of 10 Gy or a single dose of the ...

Reoxygenation-induced rigor-type contracture
Journal of Molecular and Cellular Cardiology, 2003The hypothesis tested was that reoxygenation-induced contracture of myocardial cells, a form of reperfusion injury, can be due to a rigor-type mechanism. Isolated adult cardiomyocytes were exposed to 30- or 60-min anoxia (pH 6.4) and reoxygenation (pH 7.4). In cardiomyocytes, cytosolic Ca(2+) and cell length, and in isolated rat hearts left ventricular

Tumor Reoxygenation and Postirradiation Vascular Changes
Radiology, 1978Postirradiation reoxygenation kinetics of the Walker 256 carcinoma were examined and related to radiation-induced changes in tumor vascular functions. Changes in the hypoxic cell component of irradiated Walker tumors may occur by two mechanisms. Reoxygenation of previously hypoxic cells may be due to an increased rate of blood flow in some parts of the

Sodium pump failure in hypoxia and reoxygenation
Journal of Molecular and Cellular Cardiology, 1992Sodium pump measurements have not been previously documented in the intact heart close to the onset of irreversible injury in hypoxia and reoxygenation. In the present experiments, Rb+ uptake was measured in the presence and absence of ouabain in Langendorff-perfused rat hearts. In the presence of ouabain, Rb+ uptake was increased after 10 min hypoxia (

Hypoxia and reoxygenation in human melanoma xenografts
International Journal of Radiation Oncology*Biology*Physics, 1989Tumor hypoxia and reoxygenation pattern following single dose (10.0 Gy) and fractionated (7 fractions of 2.0 Gy, 1 fraction per day) irradiation were studied in five human melanoma xenograft lines using the paired survival curve method. The hypoxic fractions differed significantly among the melanoma lines; they were found to be 6 +/- 3% (E.E.), 22 ...
