Panoramic voltage‐sensitive optical mapping of contracting hearts using cooperative multiview motion tracking with 12 cameras

The Journal of Physiology, EarlyView.
Abstact figure legend A panoramic 3D optical mapping system was developed, enabling imaging of action potential waves across the entire strongly deforming ventricular surface of beating isolated hearts. The system comprises 12 high‐speed cameras and a soccerball‐shaped imaging chamber with 48 light‐emitting diodes (LEDs).

Age‐ and sex‐specific modulation of human cardiac electrophysiology by doxorubicin

The Journal of Physiology, EarlyView.
Abstract figure legend DOX differentially impacts cardiac electrophysiology based on sex and age. Sex differences were primarily observed among younger hearts, where action potential duration (APD) prolongation was observed in females, but not in males. Created using BioRender. George, S. (2026) https://BioRender.com/wresf1k Abstract Acute doxorubicin (

Myocardial toxicity in two dogs with natural exposure to ractopamine

Veterinary Record Case Reports, Volume 14, Issue 2, May 2026.
Abstract Two dogs that lived in a farm setting were presented to the Texas A&M University Veterinary Medical Teaching Hospital's Emergency Service exhibiting muscle tremors and ventricular arrhythmias following ingestion of ractopamine, a ß‐2 agonist feed‐additive used in beef cattle, pigs and turkeys intended for slaughter to increase muscle mass.

A Review of Vagus Nerve Stimulation for Disease: Comprehensive Theory and Evidence for Mechanisms of Action

Comprehensive Physiology, Volume 16, Issue 2, April 2026.
Vagus nerve stimulation (VNS) effects span central and peripheral organ systems through diverse mechanistic pathways. This comprehensive review provides a unified synthesis of these mechanisms across neurological, cardiovascular, immunological, metabolic, and gastrointestinal domains, filling a critical gap and serving as a foundational resource for ...

Phenotyping of Fontan‐Associated Renal Physiology and Disease

Comprehensive Physiology, Volume 16, Issue 2, April 2026.
In patients with a Fontan circulation, both kidney function and glomerular injury progressively decline with age, with a stronger decline than in healthy individuals. Additionally, intrarenal haemodynamics in patients with a Fontan circulation demonstrate decreased venous and arterial compliance, evident through elevated venous impedance and renal ...
