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.

Population‐Based Study Found Low Risk of Misdiagnosing Long QT Syndrome as Breath‐Holding Spells in Swedish Children

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.

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 ...

Chronic Propafenone Application Increases Functional K_IR2.1 Expression In Vitro

Pharmaceuticals, 2023
Expression and activity of inwardly rectifying potassium (KIR) channels within the heart are strictly regulated. KIR channels have an important role in shaping cardiac action potentials, having a limited conductance at depolarized potentials but ...

Hyperthyroid Hypokalemic Periodic Paralysis in a Nepali Male; A Case Report

Clinical Case Reports, Volume 13, Issue 10, October 2025.
ABSTRACT Hyperthyroid Hypokalemic Periodic Paralysis (HHPP), marked by acute weakness and hypokalemia. Prompt potassium replacement and hyperthyroidism management are essential to prevent life‐threatening outcomes. This case highlights its presentation in a Nepali male, reinforcing the need for high clinical suspicion.

Andersen-Tawil Syndrome

Indian Pacing and Electrophysiology Journal, 2006
Andersen-Tawil syndrome (ATS) is a rare condition consisting of ventricular arrhythmias, periodic paralysis, and dysmorphic features. In 2001, mutations in KCNJ2, which encodes the α subunit of the potassium channel Kir2.1, were identified in patients ...

Exploring the perspectives and voices of students with autism on the academic adjustments they receive: A systematic review

Journal of Research in Special Educational Needs, Volume 25, Issue 4, Page 958-972, October 2025.
Abstract As the number of students with autism enrolled in general education increases, there remains a need to support their academic achievement. While much of the existing literature presents the ways that teachers can support the social, emotional or sensory needs of students with autism, research into the academic supports for school‐aged students
