The small arteries (prearteriolar vessels with lumen diameter less than approximately 500
microns) contribute importantly to and participate actively in the regulation of the peripheral …

The application of methods drawn from nonlinear and stochastic dynamics to the analysis of
cardiovascular time series is reviewed, with particular reference to the identification of …

Biomedical photonics is defined as the science of harnessing light and other forms of radiant
energy to address problems in medicine and biology. The field has experienced explosive …

The wavelet transform technique, a time-frequency method with logarithmic frequency
resolution, was used to analyze oscillations in human peripheral blood flow measured by …

Spectral analysis of the laser Doppler flow (LDF) signal in the frequency interval from 0.0095–
2.0 Hz reveals blood flow oscillations with frequencies around 1.0, 0.3, 0.1, 0.04 and 0.01 …

Contemporary measurement techniques permit the non-invasive observation of several
cardiovascular functions, both from the central and peripheral points of view. We show that …

The purpose of the present study was to compare the effects of endothelium-dependent
[acetylcholine (ACh)] and endothelium-independent [sodium nitroprusside (SNP)] …

Nitric oxide (NO) and prostaglandines (PGs) are important in regulation of vascular tone and
blood flow. Their contribution in human cutaneous circulation is still uncertain. We inhibited …

We have used the wavelet transform to evaluate the time-frequency content of laser-Doppler
flowmetry (LDF) signals measured simultaneously on the surfaces of free microvascular …

The report reviews individual‐related variables (age, sex. race, anatomical site), intra‐and
inter‐individual variation (temporal, physical and mental activity, food and drugs), and …
