ARRHYTHMOGENIC DRUGS CAN AMPLIFY SPATIAL HETEROGENEITIES IN THE ELECTRICAL RESTITUTION IN PERFUSED GUINEA-PIG HEART: AN EVIDENCE FROM ASSESSMENTS OF MONOPHASIC ACTION POTENTIAL DURATIONS AND JT INTERVALS.

Non-uniform shortening of the action potential duration (APD90) in different myocardial regions upon heart rate acceleration can set abnormal repolarization gradients and promote arrhythmia.This study examined whether spatial heterogeneities in APD90 restitution can be amplified by drugs with clinically proved proarrhythmic potential (dofetilide, q

Abstract Educational technology-based learning, or e-learning, is expected to play a significant role in medical education due to such advantages as the convenience of a Tank Tops Camis classroom without walls and the flexibility for both learners and teachers to work independently.Small-group teaching is an established educational methodology that

Aiming at addressing the problem that the joints are easily destroyed by the impact torque during the process of space robot on-orbit capturing a non-cooperative spacecraft, a reinforcement learning 4G Antennas control algorithm combined with a compliant mechanism is proposed to achieve buffer compliance control.The compliant mechanism can not only

Intracranial aneurysms (IAs) present a substantial health threat, given the potential for catastrophic ruptures and subarachnoid hemorrhages (SAH).Swift and effective measures for diagnosis and treatment are paramount to enhance patient outcomes and alleviate the associated healthcare burden.In this context, circular RNAs (circRNAs) have emerged as
