Background: The ionic mechanism underlying Brugada syndrome (BrS) arises from an imbalance in transient outward current flow between the epicardium and endocardium. Previous studies report that artemisinin, originally derived from a Chinese herb for antimalarial use, inhibits the Ito current in canines. In a prior study, we showed the antiarrhythmic effects of artemisinin in BrS wedge preparation models.

Article Synopsis
- Chronic inflammation, particularly the role of interleukin-6 (IL-6), is being explored as a target for improving hypertension treatment.
- In a study involving 1,510 participants over six years, it was found that calcium channel blockers (CCBs) with IL-6-lowering properties (specifically amlodipine and barnidipine) resulted in better blood pressure control compared to other CCBs.
- No significant differences were seen in blood pressure control among other antihypertensive classes or across different ethnic groups, indicating a need for further research into IL-6's impact on hypertension management.

Introduction: , the vector of multiple arboviral diseases, is a prime health concern worldwide. The surge in borne diseases emphasizes the urgent need for efficient vector control measures. Synthetic pesticides used traditionally, however, present environmental concerns and issues like resistance development, causing the use of higher chemical doses.

Background Alveolar echinococcosis (AE) is a fatal zoonotic disease distributed mainly in the Northern Hemisphere. At present, its curative treatment relies on surgery, and the development of effective drugs is needed. We previously demonstrated the anti-echinococcal effect of atovaquone (ATV) as a mitochondrial complex III inhibitor in both in vitro and in vivo experiments.

Cardiac alternans (C-ALT) is a phenomenon of alternating strong and weak contractions in the heart and is considered a risk factor for the development of heart failure and arrhythmias. However, no model has been reported that can induce C-ALT in vitro using human cells, and the developmental mechanism of C-ALT has not been studied using human cells. In this study, we successfully induced C-ALT in vitro using human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs).
