In this work, we investigate the role of folding/unfolding equilibrium in protein aggregation and formation of a gel network. Near the neutral pH and at a low buffer ionic strength, the formation of the gel network around unfolding conditions prevents investigations of protein aggregation. In this study, by deploying the fact that in lysozyme solutions the time of folding/unfolding is much shorter than the characteristic time of gelation, we have prevented gelation by rapidly heating the solution up to the unfolding temperature (~80 °

A 51-year-old man with normal left ventricular ejection fraction (LVEF) underwent radiofrequency catheter ablation (RFCA) for long-standing persistent atrial fibrillation (AF). After isolating the pulmonary veins (PV), we attempted to ablate multiple non-PV AF triggers evoked by isoproterenol and performed repetitive intracardiac electrical cardioversion under considerable dose of barbiturate. Finally, administration of pilsicainide was required to maintain sinus rhythm. Sixty minutes after the procedure, initiation of development of rapi
