SurGNN: Explainable visual scene understanding and assessment of surgical skill using graph neural networks [PDF]

arXiv, 2023
This paper explores how graph neural networks (GNNs) can be used to enhance visual scene understanding and surgical skill assessment. By using GNNs to analyze the complex visual data of surgical procedures represented as graph structures, relevant features can be extracted and surgical skill can be predicted.

Biodegradable and Implantable Triboelectric Nanogenerator Improved by β‐Lactoglobulin Fibrils‐Assisted Flexible PVA Porous Film

Advanced Science, EarlyView.
BF‐PVA porous film is prepared by doping BF into PVA to form hydrogel and then freeze‐drying and compression to improve the tensile resistance, bending resistance, swelling resistance, degradation time and electrical properties of PVA. Finally, the degradable triboelectric sensor made of BF‐PVA porous film and Mg film is used to realize the signal ...

TRAF3IP3 Induces ER Stress‐Mediated Apoptosis with Protective Autophagy to Inhibit Lung Adenocarcinoma Proliferation

Advanced Science, EarlyView.
Schematic diagram of the working model of TRAF3IP3 in the coordination of ER stress and autophagy related apoptosis in lung cancer cells. Abstract TNF receptor‐associated factor 3 interacting protein 3 (TRAF3IP3/T3JAM) exhibits dual roles in cancer progression. While upregulated in most malignancies and critical for immune regulation.

Fluoroscopy-based navigation system in spine surgery [PDF]

Proceedings of the Institution of Mechanical Engineers. Part H, Journal of Engineering in Medicine 221, 7 (2007) 813-20, 2007
The variability in width, height, and spatial orientation of a spinal pedicle makes pedicle screw insertion a delicate operation. The aim of the current paper is to describe a computer-assisted surgical navigation system based on fluoroscopic X-ray image calibration and three-dimensional optical localizers in order to reduce radiation exposure while ...
