A novel quantitative indicator of the left ventricular contraction based on volume changes of the left ventricular myocardial segments [PDF]

arXiv, 2018
Ejection fraction (EF) is commonly measured by echocardiography, by dividing the volume ejected by the heart (stroke volume) by the volume of the filled heart (end-diastolic volume). Utilizing volume changes of left myocardial segments per a cardiac cycle, physical laws and mathematical equations specific echocardiographic data, this paper serves to ...

KLF1 Promotes Cardiomyocyte Proliferation and Heart Regeneration Through Regulation of Wnt/β‐Catenin Signaling Pathway

Advanced Science, EarlyView.
In KLF1‐on (neonatal and Klf1 overexpression hearts) models, KLF1 regulates Wnt/β‐catenin signaling pathway and the expression of cell proliferation‐related genes via transcriptional and epigenetic mechanisms, which induces cardiomyocyte proliferation and cardiac regeneration in mice after myocardial infarction.

Stochastic Modelling and Dynamic Analysis of Cardiovascular System with Rotary Left Ventricular Assist Devices [PDF]

Mathematical Problems in Engineering, 2018, 2018
The left ventricular assist device (LVAD) has been used for end-stage heart failure patients as a therapeutic option. The aortic valve plays a critical role in heart failure and its treatment with LVAD. The cardiovascular-LVAD model is often used to investigate the physiological demands required by patients and predict the hemodynamic of the native ...

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.

Birth defects associated with paternal firefighting in the National Birth Defects Prevention Study

American Journal of Industrial Medicine, Volume 66, Issue 1, Page 30-40, January 2023., 2023
Abstract Background Few studies have evaluated birth defects among children of firefighters. We investigated associations between birth defects and paternal work as a firefighter compared to work in non‐firefighting and police officer occupations. Methods We analyzed 1997–2011 data from the multi‐site case‐control National Birth Defects Prevention ...

Inhibiting the Histone Demethylase Kdm4a Restrains Cardiac Fibrosis After Myocardial Infarction by Promoting Autophagy in Premature Senescent Fibroblasts

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

Unraveling Neurodevelopment: Synergistic Effects of Intrinsic Genetic Programs and Extrinsic Environmental Cues

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 ...
