Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion

Advanced Robotics Research, EarlyView.
A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,

Valve-in-Valve Transapical Transcatheter Aortic Valve Replacement with Concomitant Percutaneous Coronary Intervention: A Case Report

American Journal of Case Reports
BACKGROUND Valve-in-valve (ViV) transcatheter aortic valve replacement (TAVR) is increasingly used, as older high-risk patient populations require repeat aortic valve replacements. The most common approach to ViV-TAVR is through a transfemoral approach or alternative vascular access sites, such as transcarotid or transsubclavian TAVR.

Impacts of Tricuspid Regurgitation and Concomitant Tricuspid Surgery in Aortic Valve Replacement

JACC: Asia
Recent studies on the effects of preoperative tricuspid regurgitation (TR) severity and concomitant tricuspid valve (TV) surgery in patients undergoing aortic valve replacement (AVR) have yielded conflicting results, complicating the decision making on concomitant TV surgery in AVR.The purpose of this study was to investigate the impact of preoperative

Cyclic Mechanical Loading of Cardiomyocytes via Pressure‐Driven Non‐Planar Membrane Deformation in a Bioreactor System

Advanced Science, EarlyView.
In this research article, Mansoor and coworkers present a novel device that applies controlled mechanical stimuli to cardiomyocytes using pressure‐driven membrane deformation. By exposing cells to physiologically and pathologically relevant loading conditions, the platform reproduces distinct structural, functional and molecular responses associated ...
