Clinical descriptive and long‐term outcome of melanocytic uveal lesions in young dogs: 40 cases (45 eyes) including 13 cases of sector iridectomy

Veterinary Ophthalmology, Volume 28, Issue 2, Page 371-385, March 2025.
Abstract Purpose To describe the clinical features surgical technique, early and long‐term outcome with or without surgery, and histopathological findings of melanocytic anterior uveal lesions in young dogs. Methods Medical records of dogs at a guide dog facility removed from training due to a pigmented iris lesion were reviewed from 2014 to 2021 ...

Pulmonary arterial mechanoreceptors mediate sustained sympathoexcitation during high altitude hypoxia in humans

Experimental Physiology, EarlyView.
Abstract Sympathetic nervous system activation is a hallmark of high‐altitude hypoxia, yet the afferent mechanisms remain incompletely defined. We examined the relative contributions of pulmonary arterial mechanoreceptors and carotid chemoreceptors – two excitatory pathways co‐activated by hypoxia – to sustained sympathoexcitation at altitude.

A NEW MODEL OF TRANSIENT ISCHEMIA OF RABBIT EYES AND A QUANTITATIVE ASSESSMENT OF ISCHEMIA DEGREE USING OPHTHALMOPLETHYSMOGRAPHY

Российский офтальмологический журнал, 2018
Purpose: to create a model of transient eye ischemia in order to study the effectiveness of drugs affecting the intensity of ocular blood flow in ischemic conditions, and to develop a method of quantifying the extent of ischemia.

Oxidative stress and impaired cardiovagal baroreflex sensitivity in young adults with post‐traumatic stress disorder

Experimental Physiology, EarlyView.
Abstract Post‐traumatic stress disorder (PTSD) is associated with elevated cardiovascular disease (CVD) risk, yet the underlying physiological characterization in young adults remain unclear. This study examines whether autonomic and/or vascular dysfunction predominates as an early precursor to CVD development in young adults with PTSD and explores the

TMEM16A channel signalling microdomains in the regulation of vascular function

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic representation of TMEM16A channel signalling microdomains. Calcium influx or calcium release from the endoplasmic/sarcoplasmic reticulum (ER/SR) activates TMEM16A channels through interactions with regulatory proteins in vascular smooth muscle cells or endothelial cells. TMEM16A channel activation drives chloride efflux,

Update on cellular expression and function of ANO1 channels in urethral smooth muscle

The Journal of Physiology, EarlyView.
Abstract figure legend Activation of ANO1 channels and resulting Cl− efflux are suggested to modulate urethral smooth muscle contractility by enhancing Ca2+ influx via voltage‐dependent Ca2+ entry and resulting contraction in urethral smooth muscle cells.

Haemodynamic‐energetic mechanism of sudden cardiac death in severe aortic stenosis: A modelling study

The Journal of Physiology, EarlyView.
Abstract figure legend A sudden decrease in total peripheral resistance (TPR), as observed during vasovagal syncope, leads to a reduction in aortic systolic pressure (AO pressure) and afterload. In healthy individuals, the consequent decrease in left ventricular systolic pressure (LV pressure) lowers stroke work and myocardial energy expenditure.

Effectiveness of cyclopentolate 1% compared to the combination of cyclopentolate 1%, tropicamide 1%, and phenylephrine 10% in cycloplegic refractive examination

Journal of Clinical Ophthalmology and Research
Context: Refractive errors in children require appropriate eyeglass correction. Cycloplegic refraction is a method used to determine eyeglass prescriptions in children due to their high accommodative power.

Pulsed Electric Field Processing Enhances the Endothelial Bioefficacy of Red Beet (Beta vulgaris L.) Extracts by Restoring Endothelial Nitric Oxide Synthase–Nitric Oxide Signaling in High‐Fat Diet Rats

eFood, Volume 7, Issue 4, August 2026.
Pulsed electric field (PEF) processing qualitatively reshapes the phytochemical profile of red beet extracts, resulting in enhanced endothelial bioefficacy. Compared with conventional extraction, PEF‐treated extracts more effectively restore nitric oxide signaling, suppress endothelial inflammation, and normalize vascular structure in high‐fat diet ...
