Acute necrosis of the intestinal mucosa

open access: yesGastroenterology, 1982
The association of burns with erosive and necrotic lesions in the gastrointestinal mucosa was first recognized in the early part of the 19th century (l-5). The clinical history of these gastrointestinal complications clearly suggests a common pathogenetic mechanism represented by the state of shock which follows extensive skin burns.

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 ...

Polypoidal Intestinal Metaplasia and Dysplasia of the External Urethral Meatus

open access: yesCase Reports in Nephrology, 2012
Urethral mucosa with intestinal metaplasia and dysplasia is a rare occurrence. To date only a single case has been reported in a male with long-standing urethral stricture. We present a 33-year-old female with polypoid intestinal metaplasia and dysplasia

Quantitative Assessment of Gut and Vascular Barriers in TTOP, a Cartridge‐Based Bicompartmental Culture Platform

open access: yesAdvanced Materials Technologies, EarlyView.
The modular, versatile, and standardized cartridge‐based culture module allows to replicate gut and vascular barriers. Its conventional handling requirements facilitate adoption by non‐technical users, while the design allows safe manipulation and retrieval of samples for permeability assays and endpoint analysis.

Smart Sampling Capsule for Capture and Detection of Enteric Pathogens in the Small Intestine

open access: yesAdvanced Materials Technologies, EarlyView.
An ingestible smart sampling capsule for capturing asymptomatic enteric pathogens at their primary sites of interaction within the small intestine. This capability enables non‐invasive detection of early pathogen colonization within the gut environment prior to fecal shedding, providing a robust approach for pathogen surveillance and microbiome studies.
