PM2.5 Induce Endothelial‐Mesenchymal Transition and Cardiac Fibrosis via the NCOA4‐Mediated Ferritinophagy

Advanced Science, EarlyView.
This study primarily reveals that PM2.5‐derived Fe‐containing particles, particularly magnetite, are specifically enriched in the heart. Here, they interact with NCOA4 in endothelial cells, disrupt iron homeostasis by enhancing ferritinophagy, and subsequently trigger the process of EndMT through the NCOA4/KLF5 pathway.

The effects of repetitive electric cardiac stimulation in dogs with normal hearts, complete heart block and experimental cardiac arrest [PDF]

, 1955
Direct cardiac stimulation was conducted in the open chest. In normal animals, auricular stimulation at frequencies faster than the spontaneous rate caused little change in vascular pressures or cardiac output.

Arrhythmia induction using isoproterenol or epinephrine during electrophysiology study for supraventricular tachycardia [PDF]

, 2018
Background Electrophysiology study (EPS) is an important part of the diagnosis and workup for supraventricular tachycardia (SVT). Provocative medications are used to induce arrhythmias, when they are not inducible at baseline. The most common medication

A Case of Cardiomyopathy Induced by Premature Ventricular Complexes.

Circulation Journal, 2002
Tachycardia-induced cardiomyopathy is a well-known and reversible condition, but the left ventricular dysfunction caused by frequent isolated premature ventricular complexes (PVCs) has been rarely reported. Apparent dilated cardiomyopathy was resolved in a patient after the focal source of PVCs was eliminated by radiofrequency catheter ablation ...

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 (

Novel electrocardiographic criteria for the diagnosis of arrhythmogenic right ventricular cardiomyopathy [PDF]

, 2015
Aims: In order to improve the electrocardiographic (ECG) diagnosis of arrhythmogenic right ventricular cardiomyopathy (ARVC), we evaluated novel quantitative parameters of the QRS complex and the value of bipolar chest leads (CF leads) computed from the ...

2D Tellurene‐Based Optoelectronic Memristor with Temporal Dynamics for Multimodal Reservoir Computing System

Advanced Science, EarlyView.
The SPP‐treated Te‐based optoelectronic memristor demonstrates multimodal synaptic function in a single device under infrared optical and electrical stimuli. The multimode RC system is adept for processing sequence signals, including multisensory fusion and ECG pattern recognition.

The Mechanism and Potential Therapeutic Strategies of Vascular Aging

AGING MEDICINE, EarlyView.
The phenotypes of vascular aging vary across different blood vessels. Endothelial dysfunction is observable in the endothelium of all vessels, while vascular structural remodeling primarily occurs in arteries. A decline in organ vascular density mainly affects arterioles, venules, and capillaries, whereas thrombosis predominantly occurs in the ...
