Diagnostics of Microcirculatory Disorders in Children with Infectious Pathology

Проблемы особо опасных инфекций, 2012
Laser Doppler flowmetry method (LDF) was used to examine children (43 patients with enteroviral infection, 34 patients with Astrakhan rickettsial fever, and 40 healthy controls).

Laser Doppler Flowmetry in Manual Medicine Research

Journal of Osteopathic Medicine, 2014
Abstract Laser Doppler flowmetry (LDF) is commonly used in combination with reactivity tests to noninvasively evaluate skin sympathetic nerve activity and skin microvascular function. In manual medicine research, LDF has been used as a marker for global peripheral sympathetic nervous system function, but these results ...

Quantifying microvascular responses to local heating using optical coherence tomography: Comparison between skin sites and sex differences

Experimental Physiology, EarlyView.
Summary of the study design, metholodgy, results and conclusions. Abstract Due to a lack of technical capacity to directly visualise and quantify microvessels in the skin, little is known regarding regional and/or sex differences. We compared diameter, velocity, flow and density at four regional sites using a novel optical coherence tomography (OCT ...

Quantifying skin microvascular function responses to distinct forms of heat stress in humans using optical coherence tomography

Experimental Physiology, EarlyView.
Abstract Optical coherence tomography (OCT) enables visualization and quantification of the cutaneous microvasculature, yet no study has compared responses to distinct forms of heating in humans. We hypothesized that local skin heating (LH) would evoke larger responses in microvascular diameter, velocity, flow and density than passive whole‐body ...

A computational model for retinal haemodynamics under gravitational and postural variations

The Journal of Physiology, EarlyView.
Abstract figure legend The haemodynamic impact of gravitational and postural changes on the retina, and its relevance to spaceflight associated neuro‐ocular syndrome (SANS), remains incompletely characterized. This study assesses retinal haemodynamics from upright to head‐down tilt using a lumped‐parameter model that dynamically couples intraocular ...

Laser Doppler flowmetry in the optic nerve

Experimental Eye Research, 1992
Laser Doppler flowmetry (LDF) is a technique that measures relative average velocity, number and flux (number times velocity) of red blood cells in a tissue. In this paper, we demonstrate its application in the optic nerve head tissue, describe the laser delivery and light scattering detection schemes and investigate the effect of the distance between ...

Functional Segregation of Pancreatic Microcirculation Reveals Sex‐Dependent Microhemodynamic Signatures

Comprehensive Physiology, Volume 16, Issue 2, April 2026.
Pancreatic exocrine microcirculation exhibits sexual dimorphism arising from steroid–genetic interactions. Laser Doppler flowmetry combined with wavelet analysis identifies a male passive coupling phenotype aligned with systemic pressure and a female active vasomotion phenotype driven by ERβ‐mediated, NO‐dependent oscillations.

Restricting Synaptotagmin‐3 Internalization Mitigates Cerebral Ischemia/Reperfusion Injury by Curtailed Neuronal Apoptosis and Microglial Re‐Programming

CNS Neuroscience &Therapeutics, Volume 32, Issue 3, March 2026.
Restriction of Syt3 internalization by peptide 3Y conferred robust neuroprotection against cerebral ischemia/reperfusion injury. Mechanistically, 3Y suppressed neuronal apoptosis fundamentally, and additionally, these salvaged neurons orchestrated and remodulated the transformation of surrounding microglia toward an anti‐inflammatory and ...

Ferroptosis‐Driven Neuronal Damage Exacerbation in Diabetic Stroke: Implications of SLC7A11 Inhibition

CNS Neuroscience &Therapeutics, Volume 32, Issue 3, March 2026.
The current study uncovered aggravated cerebral ischemic injury and neurological dysfunction following diabetic stroke, in which ferroptosis was involved. SLC7A11 expression was inhibited in the early stages of reperfusion during diabetic stroke, and both ferroptosis inhibitors and neuron‐specific enforced expression of SLC7A11 mitigated neuronal lipid
