(Andrey V.), Meglinski, I. V. (Igor V.)

The aim of the study was to compare the metabolic activity of brain cortex after the acute hypoxia caused by the impairment of breathing or blood circulation. Male Wistar rats were randomized in two groups: impaired breathing and blood circulation fa

Analysis of changes in blood flow oscillations under different probe pressure using laser Doppler spectrum decomposition

Autor: Kozlov, I. O. (Igor O.), Zherebtsov, E. A. (Evgeny A.), Mezentsev, M. A. (Mikhail A.), Shupletsov, V. V. (Valery V.), Potapova, E. V. (Elena V.), Zherebtsova, A. I. (Angelina I.), Dremin, V. V. (Viktor V.), Dunaev, A. V. (Andrey V.), Meglinski, I. V. (Igor V.)

Presently, in the modern laser Doppler flowmetry (LDF) the distribution of blood perfusion and its changes along the Doppler shift frequencies are simply ignored and/or not properly addressed. Utilizing the registered power spectrum of photocurrent,

Evaluation of microvascular disturbances in rheumatic diseases by analysis of skin blood flow oscillations

Autor: Makovik, I. N. (Irina N.), Dremin, V. V. (Viktor V.), Zherebtsova, A. I. (Angelina I.), Krupatkin, A. I. (Alexander I.), Khakhicheva, L. S. (Lyudmila S.), Muradyan, V. F. (Vadim F.), Meglinski, I. V. (Igor V.), Dunaev, A. V. (Andrey V.)

Laser Doppler flowmetry (LDF), tissue reflectance oximetry (TRO) and pulse oximetry (PO) and cold pressor test (CPT) were used to assess the microcirculation parameters and the activation of regulatory mechanisms. LDF and TRO samples wavelet transfor

Influence of probe pressure on diffuse reflectance spectra of human skin measured in vivo

Autor: Popov, A. P. (Alexey P.), Bykov, A. V. (Alexander V.), Meglinski, I. V. (Igor V.)

Mechanical pressure superficially applied on the human skin surface by a fiber-optic probe influences the spatial distribution of blood within the cutaneous tissues. Upon gradual load of weight on the probe, a stepwise increase in the skin reflectanc
