More than 1 million permanent pacemakers are implanted worldwide each year, half of which are in patients with high-grade atrioventricular block. Pacemakers provide adequate frequency support in the initial stage, but traditional right ventricular (RV) pacing may lead to or aggravate left ventricular dysfunction and arrhythmia. Several potential risk factors for heart failure and arrhythmias after pacemaker surgery have been identified, but their occurrence remains difficult to predict clinically.

Background: Transcranial ultrasound stimulation (TUS) has shown promising prospects as a non-invasive neuromodulation technique for both animals and humans. However, ultrasonic propagation characteristics within the brain differ significantly from those in free space. There is currently a lack of comprehensive studies on the effects of skull thickness on focal point position, full width at half maximum (FWHM), and acoustic intensity.

Article Synopsis
- Recent algal blooms threaten aquatic ecosystems, making eco-friendly algae-inhibiting methods, such as using allelopathic substances, valuable for water restoration.
- This study focused on extracting flavonoids from Zanthoxylum bungeanum leaves and examining their effects on Microcystis aeruginosa algae.
- Optimal extraction conditions were found, and results indicated that these leaf extracts not only have good antioxidant activity but also disrupt photosystem II activity in algae, providing promising insights for controlling algal blooms and developing new algae-inhibiting agents.
