Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic
Advanced Robotics Research, EarlyView.Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these

Percutaneous Ureteric Stricture Dilation (PCUSD) [PDF]
, 1997 Ureteric stricture dilation as an interventional uroradiological technique was initiated locally in March 1991. In ureteric dilation two approaches are feasible.

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 ...

Imaging in the Evaluation of Endoscopic or Surgical Treatment for Achalasia
Gastroenterology Research and Practice, 2016 Purpose. Aim of the study is to evaluate the efficacy of the endoscopic (pneumatic dilation) versus surgical (Heller myotomy) treatment in patients affected by esophageal achalasia using barium X-ray examination of the digestive tract performed before ...

Stochastic Entanglement of Deterministic Origami Tentacles For Robust Robotic Grasping
Advanced Science, EarlyView.This study introduces an origami tentacle gripper to robustly grasp objects‐in air, underwater, and even in orbital space‐by exploiting a synergy between local, deterministic deformation programming and global, stochastic entanglements. A single origami tentacle can be designed to coil with a simple tendon pull.

Bistable Networks Enable Complex Shape Changes
Advanced Science, EarlyView.Transition‐controlled metamaterials are networks of bistable mechanical memory that store local binary states and express them as global shape change. By decoupling low‐force programming from high‐force holding, a single lattice is reconfigured into distinct 2D profiles and 3D surfaces without continuous actuation, enabling reusable morphing materials ...

Advanced Intelligent Systems, EarlyView.Origami turns a single silicone chamber into three different soft fluidic actuators. Crease angles alone decide whether it elongates, bends, or twists, and the fully folded chambers are cast monolithically in one day. Below 15 kPa, they reach 268% axial stretch, 72° bending, and 55° twist—no strain‐limiting layers, no rigid reinforcements, no vacuum ...

The evaluation of the soil pressure distribution and carcass stiffness resulting from pneumatic agricultural tyres [PDF]
, 2010 Introducing loads onto the soil via pneumatic tyred equipment is the major cause of compaction of agricultural soils, which causes damage to the soil-water-air-plant system.

The First Reported Case of Peroral Endoscopic Myotomy in a Child in Portugal
GE: Portuguese Journal of GastroenterologyIntroduction: Achalasia is a rare disorder, with few cases occurring during childhood. It is also part of the Allgrove syndrome phenotype and a clinical feature that has a major impact on children’s development.
