Superpixel Based Segmentation and Classification of Polyps in Wireless Capsule Endoscopy

, 2017
Wireless Capsule Endoscopy (WCE) is a relatively new technology to record the entire GI trace, in vivo. The large amounts of frames captured during an examination cause difficulties for physicians to review all these frames.

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

Advanced 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 ...

Faecal leukocyte esterase activity is an alternative biomarker in inflammatory bowel disease [PDF]

, 2015
Background: Leukocyte cytosolic proteins (e.g., calprotectin) are emerging biomarkers for inflammatory bowel disease. Leukocyte aryl esterase activity has been commonly used for sensitive detection of leukocytes in human body fluids such as urine.

Western Diet Inhibits FUT7‐Mediated Treg Intestinal Homing to Disrupt the Homeostasis of Intestinal Epithelial Cells in Crohn's Disease

Advanced Science, EarlyView.
In this study, we constructed a nanoparticle that was CD4 antibody‐mediated targeted, Fut7‐expressing plasmid‐loaded cationic liposome, namely CD4‐LDP‐Fut7. Upregulation of Fut7 expression in Tregs by using CD4‐LDP‐Fut7 can increase Treg homing to the intestine, thereby facilitating repair of the intestinal epithelial barrier and inhibiting ...
