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

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.

Excessive hypercholesterolaemia during pregnancy as a risk factor for endothelial dysfunction in pre‐eclampsia

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Excessive hypercholesterolaemia during pregnancy impairs maternal endothelial function, which, in turn, drives the development of pre‐eclampsia and may also contribute to the increased risk of later‐life cardiovascular disease in women.

Computational analysis to assess hemodynamic forces in descending thoracic aortic aneurysms

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Left: Pre‐processing. First, we perform the segmentation of the Computer Tomography angiorgraphy (angio‐CT) scans of a healthy patient, obtaining the surface of a healthy thoracic aorta with a Type III aortic arch. Then, we build nine ideal configurations with Descending Thoracic Aortic Aneurysm (DTAA), varying the aortic arch ...
