KairoSight-3.0 is a software package for semi-automated analysis of cardiac optical mapping data, providing accurate measurements of electrophysiology, calcium transients, and excitation-contraction coupling.

This study shows DEHP exposure impairs cardiac function in rats, with dose- and time-dependent effects on conduction and rhythm.

This study examines the effects of chronic phthalate exposure on rodent anxiety and cognition, finding increased anxiety-like behaviors and HPA-axis dysregulation without cognitive impairment.

This study compares the effects of bisphenol analogues on cardiac electrophysiology, finding BPA and BPF inhibit ion channels more than BPS.

This study shows that older red blood cell units affect cardiac electrophysiology, likely due to biochemical changes, including hyperkalemia, and highlights risks for certain patient groups.

The paper introduces a method to simultaneously map cardiac voltage and calcium using a single camera and path splitter, achieving high spatiotemporal resolution in whole heart preparations.

This study examines age-related changes in cardiac electrophysiology and calcium handling in rats, finding slowed conduction, prolonged action potentials, and altered gene expression in immature hearts.
