Songorine inhibits mitophagy in chronic heart failure via the TBC1D15/Fis1/Rab7A pathway
Abstract Background and purpose Songorine (SGR) is an alkaloid extracted from Aconitum carichaelii Debx. and has a demonstrated role in cardiac dysfunction. Chronic heart failure (CHF) is a severe clinical syndrome leading to functional impairment and death, primarily due to the deterioration of energy metabolism in cardiomyocytes. However, the precise

Opening closed inward rectifier potassium channel doors
Inwardly rectifying potassium (KIR) channels are essential regulators of membrane potential in excitable and non‐excitable tissues. Although KIR channels exhibit a biophysical preference for potassium influx due to voltage‐dependent block of outward current by polyamines and Mg2+, under physiological conditions, they predominantly mediate K+ efflux ...

Prehospital Risk Stratification Using Unsupervised Machine Learning in STEMI
Machine learning identified three phenotypes with 30‐day mortality of 3.4%, 22.1%, and 75%. Phenotype‐2 reveals an "occult high‐risk" group: hemodynamically stable yet six‐fold higher mortality. ABSTRACT Background ST‐elevation myocardial infarction (STEMI) exhibits substantial clinical heterogeneity complicating prehospital risk stratification ...

Technical Feasibility of the RHYTHMIA Mapping System in Pediatric Patients Weighing Less Than 20Kg
ABSTRACT Background Catheter ablation in pediatric patients remains technically challenging. The RHYTHMIA high‐density mapping system is increasingly used in pediatric electrophysiology; however, procedural experience in patients weighing less than 20 kg is limited.

Structure mirroring function: What's the ‘matter’ with the funny current?
Abstract figure legend The ‘funny’ (If) current of cardiac pacemaker cells has been first identified in the late 1970s as a major mechanism in the generation and control of cardiac pacemaking. Decades of studies have since described the properties of the funny current and of its molecular components, HCN channels, in the heart and brain, providing the ...
