P21‐Activated Kinase 2 as a Novel Target for Ventricular Tachyarrhythmias Associated with Cardiac Adrenergic Stress and Hypertrophy

open access: yesAdvanced Science, EarlyView.
Ca2+/calmodulin‐dependent kinase II (CaMKII) activation is likely driven by oxidative stress, particularly excessive reactive oxygen species (ROS) production. This study identifies P21‐activated kinase 2 (Pak2) as a novel regulator of ROS‐induced CaMKII activation and abnormal Ca2⁺ dynamics in acute adrenergic and chronic pressure‐overload stressed ...

Predictive value of HMGB1 for atrial fibrillation recurrence after cryoballoon ablation in paroxysmal atrial fibrillation patients

open access: yesClinical Cardiology, Volume 45, Issue 12, Page 1229-1235, December 2022., 2022
Abstract Background Cryoballoon ablation (CBA) is recommended for patients with symptomatic drug refractory paroxysmal atrial fibrillation (pAF). However, substantial atrial fibrillation (AF) recurrence is common during follow‐up. Searching for a potential biomarker representing both myocardial injury and inflammation to identify patients at high risk ...

Prognostic value of global longitudinal strain in hypertrophic cardiomyopathy: A systematic review and meta‐analysis

open access: yesClinical Cardiology, Volume 45, Issue 12, Page 1184-1191, December 2022., 2022
Abstract Background As previously reported, impairment of left ventricular global longitudinal strain (LVGLS) is associated with myocardial fibrosis, arrhythmias, and heart failure in hypertrophic cardiomyopathy (HCM) patients. Hypothesis This study aimed to estimate the association between LVGLS measured by echocardiography and major adverse ...

Cardiomyocyte Foxp1‐Specific Deletion Promotes Post‐injury Heart Regeneration via Targeting Usp20‐HIF1ɑ‐Hand1 Signaling Pathway

open access: yesAdvanced Science, EarlyView.
This study shows that Foxp1 regulates the USP20–HIF1ɑ‐Hand1 pathway, controlling cardiomyocyte metabolic reprogramming, proliferation, and heart regeneration. By targeting Hand1, the downstream effector, this work suggests a promising molecular target for gene therapy of heart failure, potentially guiding the development of novel molecular ...

Radiosensitization of calreticulin‐overexpressing human glioma cell line by the polyphenolic acetate 7, 8‐diacetoxy‐4‐methylcoumarin

open access: yesCancer Reports, Volume 5, Issue 12, December 2022., 2022
Abstract Background Calreticulin (CRT), an endoplasmic reticulum–resident protein generally overexpressed in cancer cells, is associated with radiation resistance. CRT shows higher transacetylase activity, as shown by us earlier, in the presence of the polyphenolic acetates (like 7, 8‐diacetoxy‐4‐methylcoumarin, DAMC) and modifies the activity of a ...

Targeting the E Prostanoid Receptor EP4 Mitigates Cardiac Fibrosis Induced by β‐Adrenergic Activation

open access: yesAdvanced Science, EarlyView.
This study explores the roles of cardiomyocyte‐ and cardiac fibroblast‐specific EP4 in isoproterenol‐induced cardiac fibrosis. The findings reveal that EP4 inhibition improves diastolic function and reduces fibrosis by modulating TGF‐β1 signaling and extracellular matrix protein production.

Arrhythmia Detection using Mutual Information-Based Integration Method [PDF]

open access: yesarXiv, 2015
The aim of this paper is to propose an application of mutual information-based ensemble methods to the analysis and classification of heart beats associated with different types of Arrhythmia. Models of multilayer perceptrons, support vector machines, and radial basis function neural networks were trained and tested using the MIT-BIH arrhythmia ...
