Heart and Vessels, 2018 Sinoatrial node fibrosis is involved in the pathogenesis of sinus sick syndrome (SSS). Transient receptor potential (TRP) subfamily M member 7 (TRPM7) is implicated in cardiac fibrosis. However, the mechanisms underlying the regulation of sinoatrial node

Local delivery of fluorescent dye for fiber-optics confocal microscopy of the living heart [PDF]
, 2014 Fiber-optics confocal microscopy (FCM) is an emerging imaging technology with various applications in basic research and clinical diagnosis. FCM allows for real-time in situ microscopy of tissue at sub-cellular scale.

Models of cardiomyocyte–non‐myocyte electrical interactions
The Journal of Physiology, EarlyView.Abstract figure legend Cardiomyocyte–non‐myocyte (CM–NM) electrotonic coupling. Left: conceptual contact‐based interactions between CM and other NM via connexin (Cx) proteins. Three basic scenarios are proposed: (i) ‘zero‐sided coupling’ where there are no electrical connections between CM and NM, (ii) ‘single‐sided coupling’ where NM are connected to ...

Control of sinus venous valve and sinoatrial node development by endocardial NOTCH1.
Cardiovascular Research, 2019 AIMS Sinus venous valve (SVV) and sinoatrial node (SAN) develop together at the sinoatrial junction during embryogenesis. SVV ensures unidirectional cardiac input and SAN generates sinus rhythmic contraction, respectively; both functions are essential ...

Effects of the network structural properties on its controllability
, 2007 In a recent paper, it has been suggested that the controllability of a diffusively coupled complex network, subject to localized feedback loops at some of its vertices, can be assessed by means of a Master Stability Function approach, where the network ...

The Journal of Physiology, EarlyView.Abstract figure legend Intricate cellular electrical coupling networks in the heart. Various cell types couple the central cardiomyocyte through gap junctional contacts, with the exception of neurons. Whether ephaptic coupling (EpC) occurs in homocellular or heterocellular contexts beyond cardiomyocyte–cardiomyocyte interactions remains unclear ...
