Influence of facial cooling on carotid body tonic activity and sensitivity

open access: yesExperimental Physiology, EarlyView.
Abstract Facial cooling can increase ventilation and augment the hypoxic ventilatory response. Whole body cooling increases both carotid body tonic activity and sensitivity; however, whether isolated facial cooling induces similar carotid body hyperexcitability was unknown.

Lower cerebral blood flow but not cerebrovascular response in elastin haploinsufficient mice

open access: yesExperimental Physiology, EarlyView.
Abstract Elastin insufficiency is associated with structural differences in the large elastic arteries and cerebral artery dysfunction. However, previous studies have not assessed potential sex differences in cerebrovascular function. We measured cerebral blood flow (CBF) using arterial spin labeling MRI at rest and in response to hypercapnia challenge

Cerebrovascular regulation during heat stress

open access: yesExperimental Physiology, EarlyView.
Abstract Given that the brain is a highly metabolic organ and is enclosed by the skull, effective regulation of cerebral blood flow (CBF), not only for oxygen and nutrients supply but also as a means of convective heat exchange, is critical for preventing excessive elevations in brain temperature.

Passive hyperthermia increases blood circulation in specific regions, largely independent of conduit artery mechanics and cardiac performance

open access: yesExperimental Physiology, EarlyView.
Abstract Passive hyperthermia increases net peripheral and systemic blood flow in humans and other animals, yet the underlying haemodynamic forces that selectively accelerate blood movement remain incompletely characterized. Wave intensity analysis offers insight into the respective contributions of the heart and the vascular system to changes in blood

Branch retinal artery occlusion due to patent foramen ovale in a teenager

open access: yesExperimental Physiology, EarlyView.
Abstract This report demonstrates the diagnostic evaluation and clinical management of a 16‐year‐old girl who developed branch retinal artery occlusion secondary to patent foramen ovale. The goal is to increase awareness of this rare presentation in adolescents among clinicians, with a summary of the important clinical features, multimodal imaging ...

Effect of repeated hot water immersion on cognitive performance, cerebrovascular function, sleep and biomarkers of neurodegeneration in older adults

open access: yesExperimental Physiology, EarlyView.
Abstract Ageing is associated with cognitive decline and increased risk of developing neurodegenerative disease. Repeated passive heating, using hot water immersion (HWI), may improve cognitive performance via improved cerebral oxygenation, but this is yet to be examined in older adults.

Exercise‐induced miR‐126 expression improves vascular health in prediabetes: A randomized controlled trial

open access: yesExperimental Physiology, EarlyView.
Abstract In this study, we investigated whether a structured aerobic exercise programme could enhance microRNA‐126 (miR‐126) expression and improve subclinical atherosclerosis markers [carotid intima–media thickness (CIMT) and ankle–brachial index (ABI)] in individuals with prediabetes.
