Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI

Experimental Physiology, EarlyView.
Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

Integrative cardiovascular dose–response to graded lower‐body negative pressure

Experimental Physiology, EarlyView.
ABSTRACT Lower‐body negative pressure (LBNP) has been posited as a potential spaceflight countermeasure to counteract the physiological deconditioning related to fluid shifts in microgravity. However, open questions remain regarding the magnitude of LBNP that should be applied.

Systolic‐dominant coronary flow in rats and mice: Challenging the diastolic paradigm across conscious and anaesthetized states

Experimental Physiology, EarlyView.
Abstract Extensive research in humans, dogs, rabbits, rats, mice and other mammals has consistently demonstrated that coronary blood flow (CBF) peaks during ventricular diastole. For example, studies using transthoracic Doppler echocardiography in anaesthetized rats and mice, isolated blood‐perfused rat hearts and Doppler probes sutured to the ...

Aortic and cardiovascular remodelling after thoracic endovascular aortic repair for blunt traumatic aortic injury in younger patients: A narrative review of physiological and clinical outcomes

Experimental Physiology, EarlyView.
Abstract Blunt traumatic aortic injury (BTAI) is severe, often fatal in younger populations due to high‐energy deceleration mechanisms. Thoracic endovascular aortic repair (TEVAR) has revolutionised BTAI treatment, surpassing the previously standard open surgical repair in mortality and complication rates.

Time‐course analysis of cerebral circulation and cardiorespiratory responses to acute central blood volume reduction in healthy young males

Experimental Physiology, EarlyView.
Abstract Central blood volume (CBV) reduction challenges circulatory and respiratory homeostasis, particularly during the initial compensatory phase (0–2 min), when rapid physiological adaptations occur. In this study, we examined dynamic cardiorespiratory responses to CBV reduction using lower‐body negative pressure (LBNP) in 11 healthy young males ...
