A Soft Robotic Model for Simulating Heart Valve Disease and Cardiac Interventions

Advanced Science, EarlyView.
This paper introduces a fully synthetic fabrication methodology for a soft robotic, in‐vitro model of the left‐heart, complete with a functioning mitral valve apparatus. With a view towards patient‐specific modeling, we demonstrate physiological flow and pressure waveforms, tunable mitral valve function with clinical imaging compatibility, and its use ...

Thermally Gated Dual‐Cascade Nanozyme for Enhanced Mild‐Temperature Photothermal Therapy

Advanced Science, EarlyView.
A thermo‐responsive cascade nanozyme (Ru‐GOx‐PNN) synergistically enhances mild photothermal therapy by dual suppression of HSP70 through ROS‐induced lipid peroxidation and ATP depletion. This intelligent system effectively overcomes thermotolerance and amplifies apoptosis, offering a safe and precise strategy for tumor treatment.

Real‐Time High‐Definition Hyperspectral Endoscopy via Spatial‐Temporal Low‐Frequency‐Stochastic Spectral Encoding

Advanced Science, EarlyView.
A real‐time, high‐definition hyperspectral endoscopy is enabled by developing a spatial‐temporal spectral encoding approach based on low‐frequency stochastic filters combined with an encoding‐guided attention network. It provides hyperspectral image of in vivo tissue with fine superficial features, enables visualization of rapid and subtle ...

A Bezoar Causing Bowel Obstruction After Roux-en-Y Gastric Bypass: A Case Report

Acta Medica Iranica, 2019
We aimed to present a patient with phytobezoar causing small bowel obstruction after Roux-en-Y gastric bypass. Thirty-year-old woman with a history of prior Roux-en-Y gastric bypass due to morbid obesity three years ago presented with colicky abdominal ...

A Strain Decoupling Packaging Strategy for High‐Fidelity Ultrathin Silicon Shape Sensors for Soft Medical Robotics

Advanced Science, EarlyView.
Reliable soft sensors are essential for precise control in soft medical robots such as endoscopes. We developed ultrathin silicon piezoresistive sensors and their oil‐lubricated slidable packaging, which enables high‐fidelity shape sensing of silicon gauges by mechanically isolating the sensing element within a dual‐layer film.

Direct Extracellular Matrix Modulation Attenuates Intestinal Fibrosis via a Fibronectin‐Targeted Approach

Advanced Science, EarlyView.
Fibronectin regulates the extracellular matrix (ECM)–myofibroblast cycle through three key steps: (1) its secretion and assembly by myofibroblasts (inhibited by pUR4); (2) collagen deposition along its scaffold (inhibited by R1R2); and (3) integrin α5β1‐mediated mechanotransduction (inhibited by ATN161).

The Impact of Time Interval to Surgery After Neoadjuvant Chemoradiotherapy on Oncological Outcomes: A Long‐Term Follow‐Up Study on Rectal Cancer Patients

Cancer Reports
Background Neoadjuvant chemoradiotherapy (nCRT) has been shown to improve prognosis in patients with locally advanced rectal cancer (LARC). However, there is still debate regarding the optimal time of surgery following nCRT.
