Targeting miRNA‐1a and miRNA‐15b: A Novel Combinatorial Strategy to Drive Adult Cardiac Regeneration
Advanced Science, EarlyView.The article explores a novel therapeutic strategy for cardiac regeneration by targeting miRNA‐1a and miRNA‐15b. Combinatorial inhibition of miR‐1a and miR‐15b enhances cardiomyocyte proliferation, improves heart function, and reduces fibrosis in myocardial infarction models.

Differentiation between mild and severe myocarditis using multiparametric cardiac magnetic resonance
Radiology Case Reports, 2023 The pathophysiology of myocarditis is associated with mild inflammation and may progress silently, or in severe cases such as fulminant myocarditis, may lead to sudden hemodynamic compromise.

Advanced Science, EarlyView.Kdm4a downregulation restrains excessive cardiac interstitial fibrosis and remodeling by depressing the premature senescence of fibroblasts in the advanced stage after MI but does not affect early ventricular rupture. It verified that Kdm4a downregulation promotes autophagy in premature senescent fibroblasts by increasing the H3K9m3 modification of the

A two phase harmonic model for left ventricular function [PDF]
arXiv, 2006 A minimal model for mechanical motion of the left ventricle is proposed. The model assumes the left ventricle to be a harmonic oscillator with two distinct phases, simulating the systolic and diastolic phases, at which both the amplitude and the elastic constant of the oscillator are different. Taking into account the pressure within the left ventricle,

Advanced Science, EarlyView.Overview of the regulation of intrinsic and extrinsic signals during neurodevelopment. Intrinsic genetic signals from NSCs, in conjunction with cues from microglia and blood vessels, collaboratively regulate the proliferation of NSCs, their fate determination, synaptogenesis, synaptic pruning, neuronal survival, and death, as well as communication ...

FastVentricle: Cardiac Segmentation with ENet [PDF]
arXiv, 2017 Cardiac Magnetic Resonance (CMR) imaging is commonly used to assess cardiac structure and function. One disadvantage of CMR is that post-processing of exams is tedious. Without automation, precise assessment of cardiac function via CMR typically requires an annotator to spend tens of minutes per case manually contouring ventricular structures ...

Advanced Science, EarlyView.During a heart attack, neutrophils rapidly activate and differentiate into a specific subset characterized by high levels of MMP9, a tissue‐damaging enzyme, via the SPI1/CST7 pathway. These neutrophils form harmful net‐like structures (Neutrophil extracellular traps, NETs) that exacerbate heart injury.

An Exploration of 2D and 3D Deep Learning Techniques for Cardiac MR Image Segmentation [PDF]
arXiv, 2017 Accurate segmentation of the heart is an important step towards evaluating cardiac function. In this paper, we present a fully automated framework for segmentation of the left (LV) and right (RV) ventricular cavities and the myocardium (Myo) on short-axis cardiac MR images. We investigate various 2D and 3D convolutional neural network architectures for
