Atrial fibrillation ablation with bipolar clamp has proved to be effective for patients with valvular atrial fibrillation. However, left pulmonary vein ablation with bipolar clamp through right minithoracotomy was considered difficult or impossible. In this report, we described a novel technique of performing concomitant Maze IV ablation procedure entirely by bipolar clamp through right minithoracotomy. Left pulmonary vein ablation with bipolar clamp was performed through an established channel and a natural space. This technique has proved to be safe and feasible and to have good clinical outcomes that may deserve further use for patients with atrial fibrillation and mitral valve disease.

During retinal visual processing, rod bipolar cells (RBC) transfer scotopic signals from rods to AII amacrine cells as second-order neurons. Elucidation of the RBC's excitation/inhibition is essential for understanding the visual signal transmission. Excitation mechanisms via mGluR6 and voltage-gated Ca2+ channels in the RBCs and GABAergic inhibitory synaptic inputs have been studied in previous studies.

Olanzapine, an atypical antipsychotic, is widely used in the treatment of schizophrenia and bipolar disorder due to its modulation of dopamine and serotonin receptor systems. While its primary action involves antagonism of dopamine D2 and serotonin 5-HT (5-hydroxytryptamine)A receptors, recent evidence suggests that olanzapine also inhibits 5-HT receptors, which are ligand-gated ion channels involved in synaptic transmission in central and peripheral nervous systems. The present study aimed to investigate the action of olanzapine on 5-HT receptor-mediated currents using whole-cell voltage-clamp recordings in NCB-20 neuroblastoma cells.

This study presents an innovative dual closed-loop DC control system for intelligent electric vehicle (EV) charging infrastructure, designed to address the challenges of high power factor, low harmonic pollution, and high efficiency in EV charging applications. The research implements a three-level Pulse Width Modulation (PWM) rectifier with a diode-clamped topology and Insulated-Gate Bipolar Transistors (IGBTs), achieving a power factor of 0.99, a total harmonic distortion (THD) of 1.
