In this study we investigated the effects of a racemic mixture of bupivacaine (RS(+/-)bupivacaine) and its isomers (S(-)bupivacaine and R(+)bupivacaine) on the Ca2+ handling by ventricular myocytes from Wistar rats. Single ventricular myocytes were e

The present paper summarizes new approaches regarding the progress done to the understanding of the interaction of Trypanosoma cruzi-cardiomyocytes. Mannose receptors localized at the surface of heart muscle cell are involved in binding and uptake of

Aims The aim of this study was to investigate whether the sera from chronic chagasic patients (CChPs) with beta-1 adrenergic activity (Ab-b) can modulate ventricular repolarization. Beta-adrenergic activity has been described in CChP. It increases th

Introduction: In chronic chagasic patients sudden death has been reported when QT interval dispersion is increased and antibodies with muscarinic-like activity have been demonstrated to trigger arrhythmias. The aims were to investigate, in vivo and i
