Effect of chronic high‐altitude hypoxia on retinal vascular phenotype, choroidal and retinal vasoreactivity in Peruvian highlanders

Experimental Physiology, EarlyView.
Abstract High‐altitude chronic hypoxia can induce excessive erythrocytosis (EE, defined as a haemoglobin concentration of ≥21 g/dL in men), leading to hyperviscosity and promoting endothelial dysfunction. We aimed to assess whether EE affects the retinal vascular phenotype and the ophthalmological vascular response to CO2.

The contribution of peripheral nerves to the pleasure from scratching an itch: Evidence from a neuronopathy participant

The Journal of Physiology, EarlyView.
Abstract figure legend Acute itch was experimentally induced using histamine and cowage in control participants (with no neuronopathy) and in IW, a participant with a large‐fibre sensory neuronopathy resulting in the loss of Aβ afferent function below C3, at the same time as largely preserving Aδ and C‐fibre function.

Short‐ and Long‐Term Impact of Exogenous Hormones on Thermoregulation in Women

American Journal of Human Biology, Volume 38, Issue 9, September 2026.
ABSTRACT Objectives How the body changes its methods of thermoregulation as part of the female ovarian cycle is a crucial aspect of human adaptive strategies to negotiate variable environments and tasks. The use of exogenous hormones to manage the ovarian cycle is a regular part of modern life but its long‐term impact on thermoregulation, particularly ...

Laser-Doppler flowmetry for estimating liver blood flow

, 1988
Whether laser-Doppler flowmetry can be used to monitor liver blood flow was evaluated in a porcine model in which portal venous blood flow was followed indirectly by electromagnetic flowmetry applied to the superior mesenteric artery, and total hepatic ...

EVALUATION OF BLOOD FLOW DISTURBANCES IN DIABETIC PATIENTS BY LASER DOPPLER FLOWMETRY

Zdravniški Vestnik, 2003
Background. The aim of this study was to investigate patients with non-insulin dependent diabetes by laser Doppler flowmetry in order to asses changes in the peripheral flow regulation during hemodynamics tests as evidence of impaired auto-regulation of ...

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 ...

Melatonin Improves Cognitive Function and Suppresses Excessive Mitophagy in Rats With Vascular Dementia

CNS Neuroscience &Therapeutics, Volume 32, Issue 9, September 2026.
CCH in BCCAO‐operated rats induces excessive hippocampal mitophagy and caspase‐3 upregulation. Two‐week daily melatonin treatment promotes CBF recovery, inhibits excessive mitophagy, and reduces caspase‐3 expression levels. These mechanisms may be associated with melatonin‐mediated amelioration of cognitive dysfunction in VaD rats.

Laser Doppler Assessment of Vasomotor Axon Reflex Responsiveness to Evaluate Neurovascular Function

Frontiers in Neurology, 2017
The vasomotor axon reflex can be evoked in peripheral epidermal nociceptive C-fibers to induce local vasodilation. This neurogenic flare response is a measure of C-fiber functional integrity and therefore shows impairment in patients with small fiber ...

Evaluation of Laser Doppler Flowmetry in Renal Transplantation

Journal of Clinical Laser Medicine & Surgery, 1994
Renal grafts are presently evaluated based on the surgeon's observation of the organ microcirculation. Effectiveness of organ microcirculation has traditionally been accomplished through evaluation of the appearance of the graft. Laser doppler flowmetry (LDF) has been suggested as a possible means to determine graft effectiveness.
