HMGB2 Promotes Cardiomyocyte Proliferation and Heart Regeneration Through MTA2‐Driven Metabolic Reprogramming

open access: yesAdvanced Science, EarlyView.
In contrast to the adult mammalian heart, which lacks regenerative capacity, the neonatal heart retains a transient regenerative capacity. In this study, high mobility group box 2 (HMGB2) is identified as a crucial protein driving heart regeneration based on comprehensive analyses using quantitative proteomics with tandem mass tag (TMT) labelling, RNA ...

Layer-specific speckle tracking analysis of left ventricular systolic function and synchrony in maintenance hemodialysis patients

open access: yesBMC Cardiovascular Disorders, 2020
Background This study investigated the value of layer-specific strain analysis by two-dimensional speckle tracking echocardiography (2D-STE) for evaluating left ventricular (LV) systolic function and synchrony in maintenance hemodialysis (MHD) patients ...

Mitochondrial Transplantation Augments the Reparative Capacity of Macrophages Following Myocardial Injury

open access: yesAdvanced Science, EarlyView.
Mitochondrial transplantation induces macrophage polarization toward an anti‐inflammatory M2 phenotype, enhances their reparative capacities, and facilitates mitochondrial transfer to cardiomyocytes, collectively promoting tissue repair and functional recovery post‐myocardial infarction.

Impact of age on pulmonary artery systolic pressures at rest and with exercise

open access: yesEcho Research and Practice, 2016
Aim: It is not well known if advancing age influences normal rest or exercise pulmonary artery pressures. The purpose of the study was to evaluate the association of increasing age with measurements of pulmonary artery systolic pressure at rest and with ...

In Vitro Flow Modelling for Mitral Valve Leakage Quantification [PDF]

open access: yes, 2009
In this study particle image velocimetry (PIV) is used to measure and visualise the blood flow through a leaking mitral heart valve. The results are compared with the results from Doppler echocardiography and computational fluid dynamics (CFD). Using CAD,

A Case Report of Acute Heart Failure Due to Infective Aortic Endocarditis Diagnosed by Point-of-care Ultrasound [PDF]

open access: yes, 2020
Introduction: Infective endocarditis (IE) is a life-threatening condition with significant morbidity and mortality, and can require surgical repair.Case Report: A 36-year-old man presented to the emergency department for worsening dyspnea and chest pain.

Right Heart Remodeling in Patients with End-Stage Alcoholic Liver Cirrhosis: Speckle Tracking Point of View [PDF]

open access: yes, 2019
BACKGROUND: Data regarding cardiac remodeling in patients with alcoholic liver cirrhosis are scarce. We sought to investigate right atrial (RA) and right ventricular (RV) structure, function, and mechanics in patients with alcoholic liver cirrhosis.

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

open access: yesAdvanced 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.

Inter-observer variability for cardiac ultrasound measurements in cats repeated at different time points in early adult life [PDF]

open access: yes, 2018
A high degree of accuracy is required when using echocardiography to diagnose hypertrophic cardiomyopathy (HCM) in cats, as variation in measurements of 0.5 mm may affect classification of individuals as ‘abnormal’.

Loss of Hepatic Angiotensinogen Attenuates Diastolic Dysfunction in Heart Failure with Preserved Ejection Fraction

open access: yesAdvanced Science, EarlyView.
Increased hepatic angiotensinogen (AGT) abundance leads to cardiac diastolic dysfunction via the AngII‐independent pathway. Liver‐derived AGT is internalized by LRP2 in cardiac endothelial cells, subsequently contributing to myocardial diastolic dysfunction by suppressing microvascular angiogenesis via inhibiting the GATA2/Pim3 pathway.
