The extensive oxygen gradient between the air we breathe (Po2~ 21 kPa) and its ultimate
distribution within mitochondria (as low as~ 0.5–1 kPa) is testament to the efforts expended …

The concentration of hydrogen peroxide (H 2 O 2) in blood and plasma is a measurement
that has often been made, but the absolute values remain unsettled due the great variability …

The primary β-globin gene mutation that causes sickle cell disease (SCD) has significant
pathophysiological consequences that result in hemolytic events and the induction of the …

The discovery of oxygen is considered by some to be the most important scientific discovery
of all time—from both physical–chemical/astrophysics and biology/evolution viewpoints. One …

Enzyme catalase seems to be the main regulator of hydrogen peroxide metabolism.
Hydrogen peroxide at high concentrations is a toxic agent, while at low concentrations it …

Abstract Peroxiredoxin 2 (Prx2), a thiol-dependent peroxidase, is the third most abundant
protein in the erythrocyte, and its absence in knock-out mice gives rise to hemolytic anemia …

Decomposition of hydrogen peroxide (H2O2) at physiological levels was studied in human
erythrocytes by means of a recently developed sensitive H2O2 assay. The exponential …

Aneurysmal subarachnoid hemorrhage frequently results in complications including
intracranial hypertension, rebleeding and vasospasm. The extravasated blood is …

Iron can be a detrimental catalyst in biological free radical oxidations. Because of the high
physiological ratio of [O2]/[H2O2](≥ 103), we hypothesize that the Fenton reaction with pre …
