Sacrificial Biofabrication for Vascularization: Concept, Materials, Technologies, and Applications

Advanced Materials, EarlyView.
Vasculature is indispensable for tissue viability in regenerative medicine. The sacrificial biofabrication enables precise fabrication of vascular channels by using temporary templates that are subsequently removed. This review defines the concept and delves into sacrificial materials, surrounding materials, fabrication technologies, and biomedical ...

A Redox‐Active and Electroactive Hydrogel Enabled by an Integrated PEDOT@PMOF Nanofiller for Post‐Infarct Myocardial Repair

Advanced Science, EarlyView.
An integrated nanoparticle PEDOT@PMOF is constructed as a redox‐active nanozyme and electroactive nanofiller in a cell‐affinity hydrogel platform for acute MI treatment. It is demonstrated that MOF‐based nanozymes have good catalytic ability, and the incorporation of PEDOT increases the conductivity.

Myocarditis Causing Premature Ventricular Contractions: Insights From the MAVERIC Registry.

Circulation: Arrhythmia and Electrophysiology, 2019
BACKGROUND Premature ventricular contractions are a common clinical presentation that drives further diagnostic workup. We hypothesize the presence of underlying inflammation is often unrecognized in these patients with a potential for continued disease ...

Premature ventricular contractions activate vagal afferents and alter autonomic tone: implications for premature ventricular contraction-induced cardiomyopathy.

American Journal of Physiology. Heart and Circulatory Physiology, 2019
Mechanisms behind development of premature ventricular contraction (PVC)-induced cardiomyopathy remain unclear. PVCs may adversely modulate the autonomic nervous system to promote development of heart failure.

Decreased RYR2 Cluster Size and Abnormal SR Ca2+ Release Contribute to Arrhythmogenesis in TMEM43‐Related ARVC

Advanced Science, EarlyView.
The TMEM43 ‐ P386S mutation causes arrhythmogenic right ventricular cardiomyopathy (ARVC) by mislocalizing itself from nuclear envelope (NE) to cytoplasm, disrupting lamin B2 (a novel TMEM43 interactor) localization, NE integrity and chromatin accessibility, causing hyper ‐ phosphorylation and reduced expression/clustering of ryanodine receptor type 2 (

High burden of premature ventricular contractions in structurally normal hearts: To worry or not in pediatric patients?

Annals of Noninvasive Electrocardiology, 2019
There is paucity of data regarding the significance of high percentage of premature ventricular contractions (PVCs) in healthy children and their impact on left ventricular (LV) function and the risk of ventricular arrhythmias.
