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 ...

Sex‐specific differences in mortality and neurocardiac interactions in the Kv1.1 knockout mouse model of sudden unexpected death in epilepsy (SUDEP)

The Journal of Physiology, EarlyView.
Abstract figure legend The Kcna1 knockout mouse model of sudden unexpected death in epilepsy (SUDEP) exhibits sex‐specific differences in SUDEP risk. Female mice exhibit a lower SUDEP risk than males, despite similar seizure characteristics and interictal cardiac function across sexes.

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,

Breathing irregularities and postnatal hypoxaemia in an experimental model of essential hypertension

The Journal of Physiology, EarlyView.
Abstract figure legend Neonatal spontaneously hypertensive rats (SHRs) exhibit inherent respiratory dysfunction in early life, including oscillatory breathing patterns and apnoeic events that cause oxygen desaturation and brain hypoxia, in addition to an impaired hypoxic ventilatory response.

Respiratory Physiotherapy Techniques in Neonatal Intensive Care Units: A Scoping Review

Physiotherapy Research International, Volume 31, Issue 4, October 2026.
ABSTRACT Background and Purpose Certain physiological characteristics increase the susceptibility of newborns, particularly preterm infants, to pulmonary collapse. In addition, newborns are prone to the accumulation of airway secretions, which, even in small volumes, can compromise respiratory function.

Non-invasive biomarkers for detecting progression toward hypovolemic cardiovascular instability in a lower body negative pressure model

Scientific Reports
Occult hemorrhages after trauma can be present insidiously, and if not detected early enough can result in patient death. This study evaluated a hemorrhage model on 18 human subjects, comparing the performance of traditional vital signs to multiple off ...

Dietary Intake of Animal and Plant‐Based Protein on Adiposity Measurements and Body Composition in Pre‐ and Postmenopausal Women: A Systematic Review of Randomized Clinical Trials

The FASEB Journal, Volume 40, Issue 15, 15 August 2026.
Graphical summary of the effects of additional intake of animal and plant proteins on anthropometric and body composition parameters in pre‐ and postmenopausal women. The arrows indicate an increase, decrease, or no significant effect. ABSTRACT This systematic review investigated the effect of protein intake on anthropometric and body composition ...

Evaluation of Five Bioelectrical Impedance Analysis Equations Against Air-Displacement Plethysmography in an Eastern European Population

Applied Sciences
Bioelectrical impedance analysis (BIA) is a widely used and an easy-to-apply method for determining body composition. However, its accuracy depends on population-specific equations.
