An age‐associated decline in the role of the sarcoplasmic reticulum and associated calcium‐handling proteins sets the pace for sinoatrial node function

The Journal of Physiology, EarlyView.
Abstract figure legend Stable, responsive pacemaking in the sinoatrial node is driven by the activity of the funny current (membrane clock), interplay of calcium cycling and release from the sarcoendoplasmic reticulum with depolarising sodium‐calcium exchange current (calcium clock). With increasing age, key proteins associated with calcium cycling are

Role of reactive oxygen species in mediating peripheral hypoxic vasodilation and sympathoexcitation at high altitude

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude acclimatisation increases muscle sympathetic nerve activity (MSNA) via activation of the arterial chemoreflex, pulmonary arterial baroreceptors and resetting of the sympathetic vascular baroreflex. However attempting to silence these mechanisms only partially normalises MSNA, implicating other contributory ...

Longer action potential duration in the Purkinje network than in the ventricular myocardium delays retrograde activation of the human His‐Purkinje system

The Journal of Physiology, EarlyView.
Abstract figure legend Activation time (AT) maps from right ventricular apical pacing in a human ventricles model with longer action potential duration in the His‐Purkinje system (HPS) than in the myocardium (MYO). For pacing with a long S1S2 coupling interval (CI), the AT from the myocardial pacing site to the first AT of the HPS (ATMYO) is longer ...

Preoperative Beta‐Hydroxy‐Beta‐Methyl‐Butyrate Supplementation Reduces Mitochondrial Dynamics Proteins and Preserves Hepatic Mitochondrial Function After Partial Hepatectomy in Mice

Acta Physiologica, Volume 242, Issue 5, May 2026.
ABSTRACT Aim The liver exhibits a remarkable regenerative capacity, enabling this organ to maintain homeostasis even after significant injury. However, hepatic regeneration requires sufficient energy to sustain cellular hypertrophy and proliferation, thus ensuring efficient tissue repair.
