The oxygen affinity of hemoglobin of both common and 2,3-diphosphoglycerate concentration-purified erythrocyte hemolysates, hemoglobin stability, 2,3-diphosphoglycerate concentration in erythrocytes, morphological blood content were studied in rabbits irradiated with X-rays in a dose of 0.155 C/kg. An increase in the oxygen affinity of common hemolysate hemoglobin at a higher 2,3-diphosphoglycerate concentration on the 1st, 4th day after irradiation and a decrease in the oxygen affinity of both common and purified hemolysate hemoglobin on the 18th-30th day after irradiation were observed. A conclusion is made that disturbance of the hemoglobin function control by 2,3-diphosphoglycerate in irradiated animals is determined by alteration of protein physicochemical properties.

4',5,6,7-tetrahydoxyisoflavone (6-hydroxygenistein, 6-OHG) is a hydroxylated derivative of genistein with excellent antioxidant activity, but whether 6-OHG can protect hypoxia-induced damage is unclear. The objective of current study was to evaluate the protective effect and underling mechanism of 6-OHG against hypoxia-induced injury via network pharmacology and cellular experiments. 6-OHG-related and hypoxia injury-related targets were screened by public databases.

The oxygenases are essential in the bioremediation of xenobiotic pollutants. To overcome cultivability constraints, this study aims to identify new potential extradiol dioxygenases using the functional metagenomics approach. RW1-4CC, a novel catechol 2,3-dioxygenase, was isolated using functional metagenomics approach, expressed in a heterologous system, and characterized thoroughly using state-of-the-art techniques.

The development of a system to leverage molecular oxygen for energy-efficient pathways required several molecular adaptations. The enzymatic reduction of dioxygen to water is one such prominent evolutionary molecular trait. Microbes evolved several enzymes capable of reducing dioxygen and, interestingly, retained multiples of them in their genomes.

The adsorption of small organic molecules on pristine VC MXene and its derivatives is investigated by first-principles density functional theory calculations. By employing state-of-the-art van der Waals (vdW) density functionals, the binding affinity of studied molecules, , CH, CO, and HO on MXene adsorbents is well described by more recent vdW functionals, , SCAN-rvv10. Although both CH and CO are nonpolar molecules, on pristine and oxygen-vacancy surfaces, they show a different range of adsorption energies, in which CH is more inert and has weaker binding than CO.
