Cognitive tasks in the human brain are performed by various cortical areas located in the cerebral cortex. The cerebral cortex is separated into different areas in the right and left hemispheres. We consider one human cerebral cortex according to a network composed of coupled subnetworks with small-world properties. We study the burst synchronization and desynchronization in a human neuronal network under external periodic and random pulsed currents. With and without external perturbations, the emergence of bursting synchronization is observed. Synchronization can contribute to the processing of information, however, there are evidences that it can be related to some neurological disorders. Our results show that synchronous behavior can be suppressed by means of external pulsed currents.

Synchrotron light sources are powerful platforms for cutting-edge, multidisciplinary research, with dozens currently in operation, construction or commissioning worldwide. It is widely recognized that different research areas have specific demands for source capabilities. For the majority of synchrotron facilities, delivering high-brightness, high-flux synchrotron radiation stably through high-current electron beams is the primary mode of operation.

Background: Catheter ablation is beneficial in patients with symptomatic persistent atrial fibrillation (PerAF), and pulsed field ablation (PFA) is a promising energy source to safely and durably create ablation lesions. However, catheter-specific "PFA waveforms and designs" result in effectiveness and safety profiles that are not transferable to other PFA technologies. A head-to-head comparison between the dual-energy, wide-footprint lattice-tip (Sphere-9, Medtronic) and pentaspline PFA catheter (Farawave, Boston Scientific) is not yet available.

Sepsis remains a leading cause of critical illness and mortality worldwide, driven by a dysregulated host response to infection and often complicated by persistent tachycardia and cardiovascular dysfunction. Increasing evidence implicates excessive sympathetic activation as a contributor to sepsis-related hemodynamic instability and myocardial injury, prompting growing interest in the use of β-adrenergic blockade as a therapeutic adjunct. This review synthesizes current data on the safety and efficacy of short-acting, cardioselective β-blockers (BBs), particularly esmolol and landiolol, in septic shock.

Mitral regurgitation is the most common valve disease worldwide. Despite its wide success in inoperable or high-risk surgical patients, transcatheter edge-to-edge repair remains limited by some anatomic features and the not negligible rate of significant residual regurgitation. Transcatheter mitral valve replacement has emerged as a viable alternative that promises to overcome these issues, but its development has been progressing slowly.

Medical devices for tricuspid regurgitation have emerged as viable treatment options for patients who do not respond to drug therapy or who are unsuitable for open-heart surgery due to high surgical risk. Recently, numerous new medical devices have been proposed and approved for use. Therefore, comprehensive reviews of the literature on the current medical devices for tricuspid regurgitation are necessary.
