Connexin43 Deficiency Leads to Ventricular Arrhythmias by Reprogramming Proline Metabolism

Advanced Science, EarlyView.
The study demonstrated that connexin43 (Cx43) knockout caused arrhythmic phenotype and decreased proline content in vitro and in vivo. Mechanistically, Cx43 interacts with the amino acid transporter SNAT2 (sodium‐dependent neutral amino acid transporter), and its deficiency disrupts proline transport and metabolism.

Remote Activation of Spinal TRPV1 by Magnetic Nanocubes Confers Cardioprotection Against Myocardial Ischemia‐Reperfusion Injury

Advanced Science, EarlyView.
Fe‐based magnetic nanocubes conjugated with TRPV1 antibodies (FeNCs‐TRPV1) are developed for the specific targeting of TRPV1 channels. Intraspinally injected FeNCs‐TRPV1 induces TRPV1 desensitization in rats exposed to repetitive and transient ACMF.

Prediction model for thyrotoxic atrial fibrillation: a retrospective study

BMC Endocrine Disorders, 2021
Background Thyrotoxic atrial fibrillation (TAF) is a recognized significant complication of hyperthyroidism. Early identification of the individuals predisposed to TAF would improve thyrotoxic patients’ management.

Synthetic Electrocardiogram Spectrogram Generation Using Generative Adversarial Network‐Based Models: A Comparative Study

Advanced Intelligent Systems, EarlyView.
Cardiovascular diseases are leading death causes; electrocardiogram (ECG) analysis is slow, motivating machine learning and deep learning. This study compares deep convolutional generative adversarial network, conditional GAN, and Wasserstein GAN with gradient penalty (WGAN‐GP) for synthetic ECG spectrograms; Fréchet Inception Distance (FID) and ...

Cough Reflex by Ventricular Premature Contractions

International Heart Journal, 2005
A 72-year-old man was referred for further assessment of a chronic cough. He noticed an association between the episodes of coughing and palpitations. Electrocardiography (ECG) revealed normal sinus rhythm and sporadic unifocal ventricular premature contractions (VPCs). Each cough was preceded by a premature beat.

A Novel Transcriptional Slippage Mechanism Rescues Dystrophin Expression from a DMD Frameshift Variant

Annals of Neurology, EarlyView.
Pathogenic DMD variants usually follow the reading‐frame rule: out‐of‐frame changes cause Duchenne muscular dystrophy, whereas in‐frame ones produce Becker muscular dystrophy (BMD). We report a 23‐year‐old man with BMD‐like weakness, calf hypertrophy, elevated creatine kinase, and dilated cardiomyopathy.
