Ultrahigh-frequency ultrasound (UHFUS) allows sharp visualization of human small muscular arteries. This may help in elucidating some aspects of the pathophysiology of arterial aging, such as the stiffness gradient between large and small conduit arteries …

We have recently developed a new and robust “chemogenetic” animal model of heart failure that is based on a central feature of heart failure in humans: an increase in redox stress in the heart. Our chemogenetic approach exploits a recombinant yeast enzyme …

Faster skin wound healers had more efficient cardiac healing after myocardial infarction (MI). Two plasma proteins at D3 MI, EAF1 and A2M, predicted MI death in 66% of cases. ApoD regulated both skin and cardiac wound healing in male mice by promoting …

Obstructive sleep apnea (OSA) is an independent risk factor for cardiovascular disease that is characterized by chronic intermittent hypoxia (CIH), and its impact is related to age. This study aims to assess the age-related impact of CIH on cardiac …

Underlying mechanisms of e-cig-induced vascular endothelial dysfunction are delineated. e-cig exposure activates and increases expression of NADPH oxidase and disrupts activation and coupling of eNOS, leading to a vicious cycle of superoxide generation …

Diabetic cardiomyopathy lacks effective and novel methods. Hydrogen sulfide (H2S) as the third gasotransmitter plays an important role in the cardiovascular system. Our study was to elucidate the protective effect and possible mechanism of H2S on diabetic …

Myocardial infarction has become one of the largest threats to human life. Myocardial ischemia and hypoxia caused by myocardial infarction are important causes of myocardial cell injury. Compared with chemical drugs, botanical drugs that are natural …

In the last decades, different strategies to model the active electromechanically coupled behaviour of the cardiac tissue were proposed in order to simulate electromechanics of the heart under healthy and pathological conditions. The main objective of …

Doxorubicin is one of the most important chemo- therapeutic drugs for the treatment of malignant tumors, but the cardiotoxicity of doxorubicin severely limits its clinical appli- cation. Increasing numbers of microRNAs (miRNAs/miRs) have been found to be …

This study tested the impact of single dose and two doses of endothelial progenitor cells (EPCs) and EPCs-derived condition medium (CM) on protecting the left-ventricular myocardium (LVM) from acute ischemia-reperfusion (IR) injury. In vitro study showed …
