Does isoproterenol promote Rapid Ryanodine Receptor Movement to Bridging Integrator 1 ( BIN1 ) -Organized Dyads?
On β-AR activation, reorganization of BIN1-induced microdomains recruits P-RyR into dyads, increasing the calcium transient while preserving electric stability. When BIN1 is reduced as in human acquired heart failure, acute stress impairs microdomain formation, limiting contractility and promoting arrhythmias.
Especially in wedge resection, the microwave tissue coagulator achieved safe resection without vascular control which differs from other new techniques. However, in larger resections, a combination with other techniques may be necessary to decrease blood loss and the rate of complications.
