The multifaceted roles of ketones in physiology

open access: yesExperimental Physiology, EarlyView.
Abstract The production of ketones, referred to as ketogenesis, plays an essential role in maintaining energy homeostasis during prolonged fasting/starvation, which primarily stems from its ability to serve as a fuel source to support neuronal ATP production, thereby limiting muscle wasting. Over the years, the field has come to appreciate that ketones

The role of orexin A in the pathogenesis of ischaemic stroke at high altitude

open access: yesExperimental Physiology, EarlyView.
Schematic illustration of the experimental design. This study investigated the role of Orexin A in the pathogenesis of ischemic stroke at high altitude. Abstract Orexin offers protection against cerebral ischaemia–reperfusion injury, with high altitude playing a key role in modulating its expression.

Combined effects of normobaric hypoxia and cold on respiratory system responses to high‐intensity exercise

open access: yesExperimental Physiology, EarlyView.
Abstract Cold temperatures (<−15°C) increase exercise‐induced bronchoconstriction (EIB), while hypoxic‐induced hyperventilation exacerbates respiratory muscle fatigue for a given exercising task. This study aimed to determine the individual and combined effects of cold and normobaric hypoxia on the respiratory system responses to high‐intensity ...

Effects of acute selective cyclooxygenase‐2 inhibition on skeletal muscle microvascular oxygenation and exercise tolerance

open access: yesExperimental Physiology, EarlyView.
Abstract The cyclooxygenase (COX) pathway regulates vascular tone and, therefore, local O2 delivery‐utilization matching. The two main isoforms, COX‐1 and COX‐2, may promote opposing effects on contracting muscle O2 transport in health by inducing vasoconstriction and vasodilatation, respectively.
