α‐Adrenergic blockade impairs ductus venosus shunting during an acute period of fetal hypoxaemia without further deficits to cerebral oxygen delivery

open access: yesExperimental Physiology, EarlyView.
Abstract The fetal circulation has unique shunts, including the ductus venosus (DV), the tone of which dictates how much substrate‐rich blood returning from the placenta is streamed preferentially away from the liver and instead towards the heart. Herein, we aimed to use clinically relevant MRI techniques in sheep to measure indirectly induced changes ...

Interpreting peripheral oxygen saturation variability in critical illness: A directional framework adjusted for hypoxia severity

open access: yesExperimental Physiology, EarlyView.
Abstract Peripheral oxygen saturation (SpO2${S_{{\mathrm{p}}{{\mathrm{O}}_2}}}$) exhibits a complex pattern of fluctuations during hypoxia, which can be quantified using entropy measures. SpO2${S_{{\mathrm{p}}{{\mathrm{O}}_2}}}$ entropy analysis provides insights into dynamic physiological regulation by non‐invasively reflecting the body's capacity to ...

Brain strain: Blood flow and metabolism in environmental extremes

open access: yesExperimental Physiology, EarlyView.
Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...

Cardiac remodelling in type 2 diabetes: Pathophysiological mechanisms and opportunities for multiscale computational modelling and simulation

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Overview of multiscale cardiac remodelling in type 2 diabetes and how to model and simulate these changes using a human‐based, multiscale computational framework. Cardiac remodelling in type 2 diabetes occurs at ionic channel, protein, cellular, tissue and whole‐organ level, affecting the electrophysiological function, mechanical
