The multifaceted roles of ketones in physiology

Experimental 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

Acute alterations in blood lactate in the setting of transient stress induced myocardial ischaemia

Experimental Physiology, EarlyView.
Abstract An elevation in resting venous blood lactate ([La−]b) levels in conditions of myocardial hypoperfusion is associated with adverse prognosis and survival. This investigation aimed to assess changes in venous [La−]b levels induced by dobutamine stress in the presence and absence of myocardial ischaemia and adverse outcomes at 1 year.

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 ...

Effects of soluble guanylyl cyclase stimulation on muscle oxygenation and exercise capacity in heart failure with mildly reduced ejection fraction

Experimental Physiology, EarlyView.
Abstract Heart failure (HF) with a mildly reduced ejection fraction (HFmrEF; 40%–49%) is present in ≤25% of HF patients. Therapeutic treatment options for HFmrEF‐associated exercise intolerance are limited. Nitric oxide (NO)‐independent stimulation of soluble guanylyl cyclase to improve peripheral vasodilatation offers a novel approach to enhance ...
