Serotonergic System‐Targeted Nucleic Acid Hydrogel Coordinates Excitability Restoration and Circuit Reconstruction for Spinal Cord Injury Therapy

open access: yesAdvanced Materials, EarlyView.
The study reports a DNA/RNA heteroduplex hydrogel (SeroPTEN‐CG) that undergoes DNase‐mediated hydrogel‐to‐nanogel transition for spinal cord injury therapy by targeting the serotonergic system, combining 5‐hydroxytryptamine (5‐HT)‐mediated excitability restoration to reactivate dormant interneurons with phosphatase and tensin homolog (PTEN)‐targeted ...

Ultra‐Sensitive Nanofiber‐Based Triboelectric Nanogenerator for Energy Harvesting and Self‐Powered Sensing

open access: yesAdvanced Materials, EarlyView.
A multidimensional molecular strategy optimizes the tribonegative layer by electrospinning PVDF‐HFP for dipole alignment and crystallinity, followed by 2D borophene doping to enhance conductivity and charge trapping. Integrated with Nylon‐66 nanofibers, the composite device delivers a record sensitivity of 53.8 ± 1.2 V kPa−1 at 3 Hz, enabling ultra ...

Cancer Cells Traverse Faster in Confined Space by Modifying Vimentin filaments With Nuclear Deformation and Promoting the Growth of Desired Tumor Spheroids

open access: yesAdvanced Materials Interfaces, EarlyView.
This study demonstrates how the Vimentin intermediate (VIM) filaments distribution/density regulates the attainment of different migration modes through cytoskeleton rearrangement and controls the nuclear morphology in migrating cells under physical confinement, which facilitates the faster traversing of those cells and the growth of post‐migration ...

A Sleeve Alters the Pressure‐Stretch Curve of a Hyperelastic Balloon to Enable Pre‐Programmed Sequencing

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This article demonstrates that encasing a hyperelastic balloon in an inextensible sleeve greatly increases its burst pressure. This simple mechanical behavior can be used to produce an asymmetric inflation‐deflation sequence for coupled balloons with different thicknesses so they could serve as a soft robot's rear and front anchors when driven from a ...

Pacemaker patient simulator

Medical & Biological Engineering & Computing, 1979
The purpose of the simulator is to establish the on demand function of pacemakers and to test electrocardiogram monitors and pacemaker test equipment. With this device, one can simulate the electrical behaviour of a paced heart, differentiating between natural sinus beats and paced beats.

Is Virtual Patient Simulation Superior to Human Patient Simulation

CIN: Computers, Informatics, Nursing, 2022
Virtual and human patient simulation methods offer an effective way to increase patient safety, reduce the incidence of errors, and improve clinical decision-making skills. The study was conducted to compare the effects of virtual and human patient simulation methods on performance, simulation-based learning, anxiety, and self-confidence with clinical ...

Patient‐specific Surgical Simulation

World Journal of Surgery, 2007
AbstractTechnological innovations of the twentieth century have provided medicine and surgery with new tools for education and therapy definition. Thus, by combining Medical Imaging and Virtual Reality, patient‐specific applications providing preoperative surgical simulation have become possible.

Simulated Patients

Pediatrics, 1978
I was interested to read the article "The Use of Paraprofessionals to Teach Interviewing Skills" by Stillman et al (Pediatrics 57:769, May 1976). Indeed, the use of "Programmed" or "simulated" patients has proven to be an important part of the birth of medical education as a science and a discipline, rather than its traditional place in the medical ...
