Intestinal Inflammation Enhances the Inhibitory Effects of Opioids on Intestinal Permeability in Mice [PDF]

, 2020
The inhibitory effects of central and peripherally acting opioid agonists on intestinal permeability (PER) were evaluated during acute and chronic intestinal inflammation in mice. Inflammation was induced by the intragastric (p.o.) administration of one (

Blending With Insulating Polymers Enables Stable Anti‐Ambipolar Characteristics in n‐Type Organic Mixed‐Conductors for Heterogeneous Spiking Neurons

Advanced Materials, EarlyView.
A polymer blend of n‐type OMIEC P(gNDI‐gT2) with insulating PMMA yields mechanically stabilized, anti‐ambipolar organic electrochemical transistors (OECTs) with tunable ionic‐electronic transport. This blending allows low‐power, fast‐spiking heterogeneous Hodgkin–Huxley neurons, enabling biomimetic frequency deconvolution and reservoir computing, which

From Water Vapor Transmission Rate (WVTR) to Intrinsic Water Vapor Permeability (WVP)

Advanced Materials, EarlyView.
Breathable membranes can appear less permeable when the measurement apparatus limits vapor transport. A calibrated four‐step model describes membrane permeation and apparatus effects as resistances in series under a common chemical‐potential driving force.

Bilayered PEDOT:PSS–Collagen Scaffolds as Functional Architectures for Tissue Engineering

Advanced Materials Interfaces, EarlyView.
A bilayered scaffold integrates collagen and PEDOT:PSS as distinct yet interconnected 3D matrices, preserving their fibrillar and conductive characteristics. Spatial compartmentalization enables independent tailoring of each domain while maintaining mechanical stability and compatibility with electrochemical monitoring, providing a multifunctional ...

Intestinal barrier permeability: the influence of gut microbiota, nutrition, and exercise

Frontiers in Physiology
The intestinal wall is a selectively permeable barrier between the content of the intestinal lumen and the internal environment of the body. Disturbances of intestinal wall permeability can potentially lead to unwanted activation of the enteric immune ...

Reducing Interfacial Separation Force in High‐Speed Constrained‐Surface Projection Stereolithography Using a Dual‐Modulus Silicone Release Film

Advanced Materials Interfaces, EarlyView.
A dual‐modulus silicone release film creates distributed stress concentrations at high‐/low‐modulus boundaries, triggering multi‐site crack initiation and rapid interfacial detachment. The architecture lowers the peak separation force by 97.6%, shortens detachment time, and enables stable continuous projection stereolithography at 720 mm h−1, offering ...

Design and Modeling of a High‐Displacement, Skin‐Integrated Flexible Electromagnetic Actuator for Haptic Interfaces in Virtual Reality

Advanced Robotics Research, EarlyView.
A flexible, skin‐integrated electromagnetic actuator is developed for wearable virtual/augmented reality (VR/AR) haptic systems. A tunable design model enables control over displacement and resonance frequency. The system is validated through a custom VR application with a 6 × 4 actuator array, demonstrating real‐time, spatially targeted tactile ...
