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 ...

Percutaneous Mitral Valve Repair

Journal of Interventional Cardiology, 2007
Nonsurgical treatment of clinically important mitral regurgitation (MR) has evolved tremendously over the past decade. Recent studies of percutaneous mitral valve repair procedures have shown that less invasive procedures are safe and can be effective in selected patients. MitraClip has been studied most extensively.

A Worm‐Inspired Origami Robot with Multimodal Locomotion for Adaptive Mobility in Complex Pipeline Environments

Advanced Science, EarlyView.
An origami worm‐inspired robot achieves multimodal locomotion in confined pipelines through mechatronic integration that embeds actuation, control, and communication within each origami module. Large, reversible configuration and dimensional changes enable 25 gaits synthesized by a unified framework across peristaltic, inchworm, and wheel‐rolling modes

Electrohydraulic Folding Ring Actuators for Radially Contracting Applications

Advanced Science, EarlyView.
This work presents an Electrohydraulic Folding Ring Actuator that combines high‐performance electrohydraulic actuation with origami‐inspired folding geometry to achieve constricting radial actuation. This integration yields significant inner lumen constriction, alongside a gripping force capable of holding objects exceeding four times the actuator's ...

Sulfated Cyclocarya Paliurus Polysaccharide Sorchestrates the Gut Microbiome to Mobilize a Host‐Derived 12‐HEPE Against Ulcerative Colitis

Advanced Science, EarlyView.
A sulfated polysaccharide (SCP) from Cyclocarya paliurus alleviates ulcerative colitis by reshaping the gut microbiome. This remodeled microbiota orchestrates the upregulation of the host‐derived lipid 12‐HEPE, which directly inhibits the TLR4/NF‐κB pathway to suppress inflammation.
