The SGLT2 inhibitor empagliflozin reduces mortality and prevents progression in experimental pulmonary hypertension
Pulmonary arterial hypertension (PAH) is a rare, but progressive and devastating vascular disease with few treatment options to prevent the advancement to right ventricular dysfunction hypertrophy and failure. Empagliflozin, a sodium-glucose cotransporter …

Cardiac sympathetic nerve transdifferentiation reduces action potential heterogeneity after myocardial infarction
Cardiac sympathetic nerves undergo cholinergic transdifferentiation following reperfused myocardial infarction (MI), whereby the sympathetic nerves release both norepinephrine (NE) and acetylcholine (ACh). The functional electrophysiological consequences …

Biophysical mechanisms for QRS- and QTc-interval prolongation in mice with cardiac expression of expanded CUG-repeat RNA
Myotonic dystrophy type 1 (DM1), the most common form of muscular dystrophy in adults, results from the expression of toxic gain-of-function transcripts containing expanded CUG-repeats. DM1 patients experience cardiac electrophysiological defects, …

The circular RNA hsa_circ_0007623 acts as a sponge of microRNA-297 and promotes cardiac repair
Circular RNAs (circRNAs) are a kind of closed loop endogenous non-coding RNAs have attracted increasing interest in recent years. However, the mechanism of circRNAs in the pathogenesis of multiple cardiovascular diseases, particularly myocardial ischemia, …

Interstitial diffuse optical probe with spectral fitting to measure dynamic tumor hypoxia
Understanding the dynamic nature of tumor hypoxia is vital for cancer therapy. The presence of oxygen within a tumor during radiation therapy increases the likelihood of local control. We used a novel interstitial diffuse optical probe to make real-time …

BRCA1 protects cardiac microvascular endothelial cells against irradiation by regulating p21-mediated cell cycle arrest
Aims: Microvascular endothelial cell dysfunction is a leading cause of radiation-induced heart disease (RIHD). BRCA1 plays an important role in DNA damage repair. The study aims to explore the effect of BRCA1 in endothelial cells involved in RIHD. …

Three-Dimensional Inflation Response of Porcine Optic Nerve Head Using High-Frequency Ultrasound Elastography
Characterization of the biomechanical behavior of the optic nerve head (ONH) in response to intraocular pressure (IOP) elevation is important for understanding glaucoma susceptibility. In this study, we aimed to develop and validate a three-dimensional …

miR-19a/19b improves the therapeutic potential of mesenchymal stem cells in a mouse model of myocardial infarction
Myocardial infarction (MI) is the cardiac emergency that may leads to myocardial necrosis. Mesenchymal stem cells (MSCs) could be used to induce myocardial differentiation. However, the efficiency remains low. The aim of this study is to explore whether …

Multi-phase catheter-injectable hydrogel enables dual-stage protein-engineered cytokine release to mitigate adverse left ventricular remodeling following myocardial infarction in a small animal model and a large animal model
Although ischemic heart disease is the leading cause of death worldwide, mainstay treatments ultimately fail because they do not adequately address disease pathophysiology. Restoring the microvascular perfusion deficit remains a significant unmet need and …

Optimizing the Geometry of Photoacoustically Active Gold Nanoparticles for Biomedical Imaging
Photoacoustics is an upcoming modality for biomedical imaging, which promises minimal invasiveness at high penetration depths of several centimeters. For superior photoacoustic contrast, imaging probes with high photothermal conversion efficiency are …
