Journal ArticleDOI
Optical measurements of intracellular oxygen concentration of rat heart in vitro
TL;DR: The results demonstrated that myoglobin is more oxygenated during the systolic and diastolic periods and deoxygenated in the resting period, whereas cytochrome a + a3 is more reduced in systole and diastsole and oxidized in the rested state.
Journal ArticleDOI
Non-synchronous behavior of neuronal activity, oxidative metabolism and blood supply during mental tasks in man
Yoko Hoshi,Hirotaka Onoe,Yasuyoshi Watanabe,Jesper L. R. Andersson,Mats Bergström,Anders Lilja,Bengt Långstöm,Mamoru Tamura +7 more
TL;DR: Are mental tasks always associated with increases in r-CBF and/or CMRO2?
Journal ArticleDOI
Noninvasive quantitative analysis of blood oxygenation in rat skeletal muscle.
TL;DR: Using the isolated perfused rat hindlimb and the fluorocarbon-transfused rat, the optical characteristics of the rat skeletal muscle in the near-infrared region are examined to determine the ratio of absorption coefficients at 700, 730, and 805 nm of oxy- and deoxy-hemoglobins of blood in the thigh muscle.
Journal ArticleDOI
Monte Carlo simulation of light transmission through living tissues
TL;DR: Temporal analyses of the transmittance have illustrated that the differences in the optical density among the slabs having different absorption coefficients with the same scattering coefficient vary linearly with time, thus verifying the microscopic Beer-Lambert law in highly scattering media when temporally resolved measurement is used.
Journal ArticleDOI
Some characteristics of the fluorescence lifetime of reduced pyridine nucleotides in isolated mitochondria, isolated hepatocytes, and perfused rat liver in situ.
TL;DR: It is concluded that the changes in fluorescence intensity observed under the various conditions can be simply explained by a change in the amount of reduced pyridine nucleotides in tissues, rather than by changes in the microscopic environment.
