Periostin‐CCL3 Feedforward Signaling Loop Promotes Cardiac Fibrosis and Cardiomyocyte Necroptosis in Arrhythmogenic Cardiomyopathy

open access: yesAdvanced Science, EarlyView.
POSTN‐CCL3 signaling forms a feed‐forward circuit between cardiomyocytes and cardiac myofibroblasts in arrhythmogenic cardiomyopathy. POSTN activates JNK/RIP3‐dependent necroptotic signaling and JNK/ETS2‐induced CCL3 expression in cardiomyocytes. In turn, CCL3‐CCR5 signaling in cardiac myofibroblasts activates NF‐κB/p65 and promotes POSTN expression ...

Reproducibility of parameters assessing right ventricular systolic function in patients after an acute myocardial infarction

open access: yesRomanian Journal of Internal Medicine
To assess reproducibility of 2D echocardiography parameters of right ventricular systolic function, such as tricuspid annular plane systolic excursion, right ventricular systolic wave velocity, fractional area change, and 3D right ventricular ejection ...

Mitral Paravalvular Leak 3D Printing from 3D-Transesophageal Echocardiography

open access: yesAnatolian Journal of Cardiology, 2023
Background: Paravalvular leaks can be detected in almost 15% of patients after mitral valve prosthesis implantation. This complication can result in congestive heart failure and hemolysis.

An Extracellular Pore‑Targeting Peptide Defines a Designable Allosteric Site in TRPV2

open access: yesAdvanced Science, EarlyView.
Structure‐guided peptide engineering yields Depiv2, a highly potent and subtype‐selective TRPV2 inhibitor that binds to the extracellular pore and remodels it into a closed, non‐conductive state. Depiv2 suppresses pathological cardiac hypertrophy, establishing the TRPV2 outer pore as a designable interface for selective peptide modulation.

A Spatiotemporal Single‐Cell Atlas Uncovers Dysregulated ECM Dynamics and Septal Remodeling Arrest in Human Ventricular Septal Defects

open access: yesAdvanced Science, EarlyView.
Integrating single‐cell and spatial transcriptomics reveals human ventricular septal defect (VSD) as a disease of microenvironmental insufficiency and structural remodeling arrest. Attenuated endothelial‐fibroblast crosstalk, alongside downregulated THBS1/TGF‐β1 and MMP2 signaling networks, impairs the endothelial‐to‐mesenchymal transition (EndoMT) and

Computer-based training in two-dimensional echocardiography using an echocardiography simulator

open access: yes, 2022
S.362-366Two-dimensional (2D) echocardiography is a user-dependant technique that poses some inherent problems to the beginner. The first problem for beginners is spatial orientation, especially the orientation of the scan plane in reference to the 3 ...

Targeting Nupr1‐Mediated p53 Mitochondrial Sequestration Alleviates Aortic Dissection by Restoring the Gadd45b‐Dependent Survival Program

open access: yesAdvanced Science, EarlyView.
This study identifies Nupr1 as a crucial stress‐responsive orchestrator driving AD. Under severe stress, Nupr1 massively accumulates within mitochondria to sequester p53, triggering apoptosis and concurrently repressing the Gadd45b‐mediated survival program.

Ultrasound‐Triggered piRNA Delivery Using Biomimetic Phase‐Changeable Nanoparticles for Theranostics of Myocardial Infarction

open access: yesAdvanced Science, EarlyView.
A biomimetic ultrasound‐responsive piRNA delivery nanoparticle platform (piR‐NPs) enables targeted delivery and ultrasound (US)‐triggered release of piR‐1873 in infarcted myocardium. The released piR‐1873 suppresses Usp2‐mediated RIP1/RIP3/MLKL necroptosis, reduces myocardial injury and fibrosis, and promotes cardiac functional recovery, providing a ...

An Overview for Echocardiography Techniques-An Updated Review for Modern and Advanced Techniques and Innovations [PDF]

open access: yesJournal of Medical and Life Science
Background: Echocardiography has evolved significantly since its inception in the 18th century, with foundational contributions from Lazzaro Spallanzani and practical applications pioneered by Hertz and Edler in 1954. Initially reliant on M-mode imaging,
