3D‐Printed Gastrointestinal Stents: In Vivo Evaluation in a Swine Small Bowel Perforation Model

open access: yesAdvanced Healthcare Materials, EarlyView.
Gastrointestinal fistulae and perforations can lead to severe complications including sepsis and patient death. In this work, the efficacy of 3D‐printed gastrointestinal stents composed of poly‐lactic‐acid (PLA) was evaluated in an in vivo swine model.

Helicobacter Pylori Infection in Superficial Gastritis, Erosive Gastritis and Gastric Ulcer [PDF]

open access: yes, 2012
Background: Helicobacter pylori (H. pylori) infection leads to inflammation of the gastric mucosa. It damages the gastric epithelium and related to the risk of developing gastric cancer. Over time, it may develop into the development of glandular atrophy

Autonomous Hydrogel Actuators Programmed by Endogenous Biochemical Logic for Dual‐Stage Morphing and Drug Release

open access: yesAdvanced Materials, EarlyView.
A 3D‐printed BSA–PEGDA bilayer actuator performs biochemical logic, bending autonomously in acid and releasing its drug payload only when both acid and pepsin are present. This dual‐stage, enzyme‐gated mechanism enables autonomous catch‐and‐release motion and controlled gastric drug delivery, representing a programmable soft material powered by ...

H. PYLORI INFECTION, ENDOSCOPIC, HISTOLOGICAL ASPECTS AND CELL PROLIFERATION IN THE GASTRIC MUCOSA OF PATIENTS SUBMITTED TO ROUX-EN-Y GASTRIC BYPASS WITH CONTENTION RING: a cross sectional endoscopic and immunohistochemical study

open access: yesArquivos de Gastroenterologia
Background Morbid obesity treatment through vertical gastroplasty Roux-en-Y gastric bypass initially used a contention ring. However, this technique may create conditions to the development of potentially malign alterations in the gastric mucosa ...

Occurrence of acute oesophageal necrosis (black oesophagus) in a single tertiary centre [PDF]

open access: yes, 2019
Acute oesophageal necrosis (AON) is a rare condition characterised by the endoscopic finding of diffuse, circumferential, black mucosal pigmentation of the oesophagus, which typically stops at the gastro-oesophageal junction.

Mucosa‐Interfacing Capsule for In Situ Sensing the Elasticity of Biological Tissues

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
A fundamental mechanism of palpating soft materials is reported to sense deep tissue elasticity in situ with minimal invasion using the interaction between the robot palpation unit and soft tissues. Both the robot locomotion and elasticity sensing functions are remotely controlled by external magnetic fields, while the sensing data are wirelessly ...

The role of heterotopic gastric mucosa with or without colonization of Helicobacter pylori upon the diverse symptomatology of Meckel's diverticulum in children

open access: yesThe Turkish Journal of Pediatrics, 2001
The roles of heterotopic gastric mucosa either with or without colonization of Helicobacter pylori (HP) upon the diverse symptomatology of Meckel's diverticulum (MD) in children have been evaluated retrospectively.

Advances in Safe, Flexible, and Stretchable Batteries for Wearable Applications

open access: yesAdvanced Materials Technologies, EarlyView.
Unlike previous reviews centered on component‐based deformability, this work highlights safety‐driven design strategies for flexible and stretchable batteries. By integrating material‐level engineering, geometry‐controlled structures, biocompatibility, and self‐protection mechanisms, it establishes a unified framework that connects mechanical ...
