Small‐conductance Ca2⁺‐activated K⁺ channels in cardiac excitation–contraction coupling: Bridging mitochondria, sarcolemma and antiarrhythmic therapy

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondrial SK channel enhancement reduces cardiac arrhythmia trigger. Spontaneous sarcoplasmic reticulum (SR) Ca2+ release via hyperactive RyR2s underlies an increased arrhythmia trigger, promoting early and delayed afterdepolarizations during stress. Hyperactive RyR2s causes rise in cytosolic [Ca2+] during diastole. Clearance

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

The Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

Management Strategies for Refractory Esophageal Varices

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Refractory esophageal varices that are difficult to control or unresponsive to endoscopic treatment remain a major clinical challenge in the management of portal hypertension. This review provides a comprehensive overview of treatment strategies for these cases, along with a comparative analysis of the American Association for the Study of ...

Polyglycolic Acid Sheet Application to Refractory Delayed Bleeding After Rectal Endoscopic Submucosal Dissection: A Case Report

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT A man in his 50s underwent endoscopic submucosal dissection (ESD) for a rectal tumor measuring 28 mm. He was not taking any antithrombotic medication. On the third, 11th, 18th, and 24th days after the procedure, bleeding was observed from different areas of the ulcer bed margin and was managed with hemostatic forceps.

Non‐RASopathy Genetic Syndromes Identified as the Molecular Cause of Disease in Patients Previously Diagnosed With Noonan Syndrome

American Journal of Medical Genetics Part A, Volume 200, Issue 3, Page 661-672, March 2026.
ABSTRACT Noonan Syndrome (NS) is a clinically and genetically heterogeneous condition characterized by typical facial dysmorphisms, short stature, congenital heart defects, and developmental delays. While variants in genes such as PTPN11, SOS1, and RAF1 account for most genetically confirmed cases, diagnosis is challenging due to phenotypic overlap ...
