Conformable Microelectrode Arrays Integrated with a Scoop‐Shaped Slide‐Well for Dynamic Electrophysiological Profiling of Patient‐Derived Cardiac Organoids

Advanced Science, Volume 13, Issue 31, 4 June 2026.
A flexible, ultrathin multi‐channel microelectrode array (MEA) conformally integrated onto a curved slide‐well enables stable electrical interfacing with 3D cardiac organoids. The geometry‐guided self‐alignment allows simultaneous recording of extracellular field potentials and contractile motion from irregular, beating tissues.

Andersen syndrome: an association of periodic paralysis, cardiac arrhythmia and dysmorphic abnormalities [PDF]

Arquivos de Neuro-Psiquiatria, 2006
Andersen syndrome (AS) is a rare disease characterized by the presence of periodic paralysis (PP), cardiac arrhythmia and dysmorphic abnormalities. We report herein the first Brazilian patient presenting AS who also had obesity, obstructive sleep apnea ...

PA-6 inhibits inward rectifier currents carried by V93I and D172N gain-of-function KIR2.1 channels, but increases channel protein expression

Journal of Biomedical Science, 2017
Background The inward rectifier potassium current IK1 contributes to a stable resting membrane potential and phase 3 repolarization of the cardiac action potential.

The research of ion channel‐related gene polymorphisms with atrial fibrillation in the Chinese Han population

Molecular Genetics & Genomic Medicine, 2019
Background Atrial fibrillation (AF) is one of the common arrhythmia in clinics. Its incidence is high among the elderly. This study aimed to identify a possible connection between ion channel‐related gene polymorphisms and the risk of AF. Methods A total

Sanger sequencing as a first-line approach for molecular diagnosis of Andersen-Tawil syndrome [version 1; referees: 2 approved]

F1000Research, 2017
In 1977, Frederick Sanger developed a new method for DNA sequencing based on the chain termination method, now known as the Sanger sequencing method (SSM).

Selective loss of Cx40 and conduction abnormalities underlie enhanced atrial fibrillation susceptibility in a HFpEF model in male mice

Physiological Reports, Volume 14, Issue 11, June 2026.
Abstract Heart failure with preserved ejection fraction (HFpEF) is frequently complicated by atrial fibrillation (AF), yet the mechanisms underlying AF vulnerability prior to or independent of extensive structural remodeling remain incompletely understood.

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 ...

Genome-wide joint meta-analysis of SNP and SNP-by-smoking interaction identifies novel loci for pulmonary function.

PLoS Genetics, 2012
Genome-wide association studies have identified numerous genetic loci for spirometic measures of pulmonary function, forced expiratory volume in one second (FEV(1)), and its ratio to forced vital capacity (FEV(1)/FVC).
