Photosensitization-induced Calcium Overload in Cardiac Cells: Direct Link to Membrane Permeabilization and Calcium Influx

The purpose of the present study was to gain new insight regarding the role membrane permeabilization plays in the photosensitization-induced increase in intracellular calcium concentration. During continuous rose bengal photosensitization we monitored the contractile state (relaxed or hypercontract...
