TLDR
Findings indicate that at normothermic rest, the decoding rule from vasoconstrictor skin SNA to skin blood flow of skin is characterized by low-pass filter with 3-4s of pure time delay, and that the vasoconStrictorskin SNA contributes to a half of fluctuation of skinBlood flow in the condition.About:

Blood Flow Oscillations at a Frequency of about 0.1 Hz in Skin Microvessels Do Not Reflect the Sympathetic Regulation of Their Tone
TL;DR: Wavelet analysis of blood flow oscillations recorded with laser Doppler flowmetry in finger glabrous skin microvessels with different variations in the syndromes of hand and foot sympathectomy and denervation found no appreciable influence of the sympathetic vasomotor activity and the corresponding influence of catecholamines on the amplitude and frequency of vasomotions.

Analysis of sympathetic neural discharge in rats and humans
TL;DR: The aim of this paper is to address some aspects related to the recording, analysis and interpretation of sympathetic activity in rats and humans, with special emphasis on analysis in the frequency domain.

Closed‐loop spontaneous baroreflex transfer function is inappropriate for system identification of neural arc but partly accurate for peripheral arc: predictability analysis
TL;DR: Although the spontaneous baroreflex transfer function obtained by closed‐loop analysis has been believed to represent the neural arc function, it is inappropriate for system identification of the neural arcs but is essentially appropriate for the peripheral arc under resting condition, when compared with open‐loop transfer functions that have good predictabilities of time‐series output dynamics from input signals.

TL;DR: It is concluded that NIRTRS can provide useful information for assessing BAT-d in a simple, rapid, non-invasive way, although further validation study is still needed.

Efficacy of Aspirin on Improvement of Peripheral Blood Circulation in Mice
TL;DR: Findings indicate that whole-body cooling is characterized by peripheral circulatory disturbance, which also influences the efficacy of aspirin in improving the peripheral blood circulation.

Primer of biostatistics
TL;DR: The text focuses on practical areas of statistics in terms of their relevance to biomedical applications, statistical hypothesis testing and estimation and an easy-to-use menu-driven program which performs 17 commonly used statistical tests featured in the text.

General Characteristics of Sympathetic Activity in Human Skin Nerves
TL;DR: The sympathetic activity was not pulse synchronous as in muscle nerves and the spontaneous sympathetic volleys occurred largely independently of spontaneous blood pressure variations, indicating a relative lack of baroreflex control of the vasoconstrictor outflow to the skin.

Peripheral Sympathetic Neural Activity in Conscious Humans
B G Wallin,J Fagius +1 more
TL;DR: Only two sub divisions of the anatomically multifaceted sympathetic nervous system are accessible to study and the results have allowed a number of conclusions, not only about peripheral sympathetic function but also about reflex patterns and hence general principles of sympathetic regulation.

Laser-Doppler measurement of skin blood flow: comparison with plethysmography
TL;DR: LDF appears to provide a good indicator of the response pattern of SkBF from the region of illuminated skin, however, variability in the relationship to total SkBF and uncertainties in the value of LDF at zero SkBF make quantitative use difficult.
