The assay of catalases and peroxidases.
TLDR
Two methods are described for the catalase assay by disappearance of peroxide are: ultraviolet spectrophotometry and permanganate titration and indirect measurements of the decrease of light absorption caused by the decomposition of hydrogen peroxide byCatalase.
The mitochondrial generation of hydrogen peroxide. General properties and effect of hyperbaric oxygen.
TLDR
It is postulated that in addition to the well-known flavin reaction, formation of H( 2)O(2) may be due to interaction with an energy-dependent component of the respiratory chain at the cytochrome b level.
The cellular production of hydrogen peroxide.
TLDR
The cytochrome c peroxidase assay is suitable for use with subcellular fractions from tissue homogenates as well as with pure enzyme systems to measure H(2)O( 2) generation and can be made on the basis of the rates with the isolated fractions under physiological conditions.
Time resolved reflectance and transmittance for the non-invasive measurement of tissue optical properties.
TLDR
A simple model is developed, based on the diffusion approximation to radiative transfer theory, which yields analytic expressions for the pulse shape in terms of the interaction coefficients of a homogeneous slab.
The respiratory chain and oxidative phosphorylation.
TLDR
How the respiratory chain and oxidative phosphorylation works and which substances may disable it are explained.
Validation of near-infrared spectroscopy in humans.
TLDR
760-800 nm absorption is closely correlated with venous oxygen saturation, minimally affected by skin blood flow, altered by changes in limb perfusion, and primarily derived from deoxygenated hemoglobin and not myoglobin.
Recovery from exercise-induced desaturation in the quadriceps muscles of elite competitive rowers.
TLDR
The Hb/Mb resaturation times provide a noninvasive localized indication of the degree of O2 delivery stress as evoked by rowing ergometry and may provide directions for localized muscle power output improvement for particular individuals in rowing competitions.
