Tooth-shaped plasmonic waveguide filters with nanometeric sizes [PDF]

Opt. Lett. 33, 2874-2876 (2008), 2009
A novel nanometeric plasmonic filter in a tooth-shaped Metal-Insulator-Metal waveguide is proposed and demonstrated numerically. An analytic model based on the scattering matrix method is given. The result reveals that the single tooth-shaped filter has a wavelength filtering characteristic and an ultra-compact size in the length of a few hundred ...

Use of the Deep Learning Approach to Measure Alveolar Bone Level [PDF]

arXiv, 2021
Abstract: Aim: The goal was to use a Deep Convolutional Neural Network to measure the radiographic alveolar bone level to aid periodontal diagnosis. Material and methods: A Deep Learning (DL) model was developed by integrating three segmentation networks (bone area, tooth, cementoenamel junction) and image analysis to measure the radiographic bone ...

Apoptotic Vesicles Derived from Mesenchymal Stem Cells Ameliorate Hypersensitivity Responses via Inducing CD8+ T Cells Apoptosis with Calcium Overload and Mitochondrial Dysfunction

Advanced Science, EarlyView.
The therapeutic potential of ApoVs derived from stem cells from human exfoliated deciduous teeth (SHED‐ApoVs) in the treatment of CD8+ T cell‐mediated hypersensitivity reactions is noteworthy. SHED‐ApoVs are capable of fusing with the plasma membrane of CD8+ T cells, which subsequently triggers a series of events characterized by calcium overload ...
