Alternative Lead ECG Placements
Annals of Noninvasive Electrocardiology, Volume 31, Issue 3, May 2026.Alternative ECG lead placements can improve diagnostic yield when the standard 12‐lead ECG is suboptimal or infeasible. This review summarizes practical, scenario‐driven modifications (right‐sided, posterior, seated/prone, Lewis, Fontaine, torso‐based, and monitoring configurations) to better detect ischemia, right ventricular disease/ARVD, and ...

Stabilizing Extreme Few‐Shot ECG Classification via Self‐Supervised Contrastive Pretraining
Annals of Noninvasive Electrocardiology, Volume 31, Issue 3, May 2026.Under extreme few‐shot ECG classification, supervised training frequently collapses to degenerate solutions. Self‐supervised pretraining stabilizes optimization, eliminates early collapse, and enables reproducible multi‐class rhythm classification with limited labeled data. ABSTRACT In clinical electrocardiogram (ECG) analysis, high‐quality annotations

Acta Paediatrica, Volume 115, Issue 5, Page 1116-1125, May 2026.ABSTRACT Aim An electrocardiogram is commonly recommended in breath‐holding spell management, mainly to rule out long QT syndrome. This retrospective study investigated the risk of long QT syndrome being misdiagnosed as breath‐holding spells in a paediatric population in southern Sweden.

Molecular basis for a pore block of Tentonin 3 expressed in HEK293 cells by a conopeptide, NMB‐1
British Journal of Pharmacology, Volume 183, Issue 9, Page 1845-1859, May 2026.Background and Purpose Tentonin 3 (TTN3/TMEM150C) is a mechanosensitive ion channel that plays critical roles in mechanotransduction processes. TTN3 forms a tetramer with a predicted rectangular shape and a central pore. A conotoxin ρ‐TIA and its synthetic analog, noxious mechanosensation blocker 1 (NMB‐1), were initially developed to inhibit slowly ...

Opening closed inward rectifier potassium channel doors
British Journal of Pharmacology, Volume 183, Issue 10, Page 2197-2218, May 2026.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 ...

SORBS2: A Molecular Nexus in Multisystem Diseases Through Scaffold‐Mediated Regulation
Journal of Cellular and Molecular Medicine, Volume 30, Issue 9, May 2026.ABSTRACT Sorbin and SH3 Domain Containing 2 (SORBS2), a multifunctional scaffold protein harbouring Sorbin homology (SoHo) and Src homology 3 (SH3) domains, serves as a molecular hub in human diseases by integrating cytoskeletal remodelling, signal transduction and RNA metabolic regulation. This study systematically analyses SORBS2's molecular features,
