Developmentally Inspired Bioprinting of Nascent Multicellular Human Heart Tissue Through in Situ Differentiation and Morphogenesis of iPSCs

Advanced Science, EarlyView.
A developmentally inspired bioprinting approach enables the fabrication of pluripotent tissues that undergo shape‐morphing and in situ cardiac lineage specification. This method employs embedded bioprinting to deposit iPSCs within soft granular hydrogels to create pluripotent tissue constructs that undergo cell‐mediated shape morphogenesis.

Engineering Approaches to Modify Immunomodulatory Functions of Mesenchymal Stromal Cells (MSCs): Tissue Regeneration and Clinical Application

Advanced Science, EarlyView.
Mesenchymal stromal cells (MSCs) show promise for treating immune‐related disorders through immunomodulation and tissue regeneration. This review gives a brief overview of current clinical approval of MSC therapies. It also discussed how bioengineering, including genetic modification, biomaterial delivery, extracellular vesicles, and iPSC‐derived MSCs,

The KCa2 Channel Inhibitor AP14145, But Not Dofetilide or Ondansetron, Provides Functional Atrial Selectivity in Guinea Pig Hearts

Frontiers in Pharmacology, 2019
Background and Purpose: Prolongation of cardiac action potentials is considered antiarrhythmic in the atria but can be proarrhythmic in ventricles if the current carried by Kv11.1-channels (IKr) is inhibited.

Rate-dependency of action potential duration and refractoriness in isolated myocytes from the rabbit AV node and atrium [PDF]

, 2000
During atrial fibrillation, ventricular rate is determined by atrioventricular nodal (AVN) conduction, which in part is dependent upon the refractoriness of single AVN cells.

A Stretchable, Mechanically‐Interlocked Polyrotaxane Hydrogel for Wearable Motion and Electrophysiological Monitoring

Advanced Science, EarlyView.
A mechanically interlocked polyrotaxane hydrogel integrates sliding macrocycles within a covalent network, yielding skin‑like softness, high stretchability, robust adhesion, and stable ionic conductivity. This multifunctional interface enables simultaneous high‑fidelity monitoring of human motion and epidermal electrophysiological signals (ECG/EMG ...

Similarities and differences of clinical characteristics between Brugada syndrome and early repolarization syndrome

Journal of Arrhythmia, 2013
Early repolarization (or J wave) is a common electrocardiographic finding that occurs in 1% to 10% of healthy persons. It has been generally considered benign for decades.
