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

Transcatheter Mitral Valve Replacement in the Transcatheter Aortic Valve Replacement Era

Journal of the American Heart Association, 2019
After the success and worldwide adoption of transcatheter aortic valve replacement (TAVR), the percutaneous replacement of a diseased mitral valve (MV) rapidly became a target for investigators and industry. The rejuvenated enthusiasm of industry in this field is also corroborated by the fact that, in 2015, ≈2.5 billion dollars were invested in MV ...

A Hollow Shell‐Lattice Soft Robot in Flexible Pipelines with Flowing Fluids

Advanced Science, EarlyView.
This study proposes a novel shell‐lattice robot with hollow bodies, capable of crawling through pipes with flowing fluids of high velocities and viscosities and mixed with impurities. The robot also features capabilities of crawling with high payloads, in curved pipes, and unthethered crawling. These unique properties make this robot high promising for
