Oxygen Activation and Radical Transformations in Heme Proteins and Metalloporphyrins [PDF]

, 2018
As a result of the adaptation of life to an aerobic environment, nature has evolved a panoply of metalloproteins for oxidative metabolism and protection against reactive oxygen species. Despite the diverse structures and functions of these proteins, they

Transnitrosation Signals Oxyhemoglobin Desaturation [PDF]

Circulation Research, 2008
See related article, pages 545–553 Erythrocytes dilate peripheral blood vessels as a function of oxyhemoglobin desaturation.1 This effect increases regional blood flow to hypoxic tissues. The mechanisms underlying the peripheral vasodilatory effects of desaturating erythrocytes are incompletely understood but do not involve activation of local ...

The oxyhemoglobin reaction of nitric oxide [PDF]

Proceedings of the National Academy of Sciences, 1999
The oxidation of nitric oxide (NO) to nitrate by oxyhemoglobin is a fundamental reaction that shapes our understanding of NO biology. This reaction is considered to be the major pathway for NO elimination from the body; it is the basis for a prevalent NO assay; it is a critical feature in the modeling of NO diffusion in the circulatory ...

Hematological and Morphological Analysis of the Erythropoietic Regenerative Response in Phenylhydrazine-induced Hemolytic Anemia in Mice [PDF]

, 2008
In this study we developed a mouse model of Phenylhydrazine (PHZ) -induced hemolytic anemia to study  erythropoietic regenerative response through clinical, pathological, and morphological studies. Hemolytic  anemia was induced in female mice (CF1) using

Identification of the intermediate allosteric species in human hemoglobin reveals a molecular code for cooperative switching [PDF]

, 1991
The 10 ligation species of human cyanomethemoglobin were previously found to distribute into three discrete cooperative free energy levels according to a combinatorial code (i.e., dependent on both the number and configuration of ligated subunits ...
