Probing Early Particle‐Cell Membrane Interactions via Single‐Cell and Single‐Particle Interaction Analysis

Advanced Functional Materials, EarlyView.
The pre‐internalization phase of endocytosis remains poorly characterized at single‐cell levels. Single‐cell pre‐internalization mechanics are investigated using advanced robotic techniques. Cancer cells exhibit biphasic adhesion – rapid initial binding followed by reinforcement – while fibroblasts show gradual engagement.

A Tensor Factorization Method for 3D Super-Resolution with Application to Dental CT [PDF]

, 2018
Available super-resolution techniques for 3D images are either computationally inefficient prior-knowledge-based iterative techniques or deep learning methods which require a large database of known low- and high-resolution image pairs. A recently introduced tensor-factorization-based approach offers a fast solution without the use of known image pairs

Controlled Release of Human Dental Pulp Stem Cell‐Derived Exosomes from Hydrogels Attenuates Temporomandibular Joint Osteoarthritis

Advanced Healthcare Materials, EarlyView.
Exosomes can reduce tissue damage in temporomandibular joint osteoarthritis (TMJOA), but rapid clearance limits their efficacy. This study encapsulates exosomes in hyaluronic acid hydrogels for controlled release. In a rat model, hydrogel‐encapsulated exosomes outperform free exosomes in preserving bone integrity and reducing tissue destruction ...

Cone-beam CT for Dental Radiography [PDF]

arXiv, 2018
The cone beam computed tomography (CBCT) technique was first inserted in dental imaging 15 years ago. Due to this technique 3D imaging in dentistry has been excessively changed. The purpose beyond using CBCT instead of computed tomography (CT) imaging is that CT can not be used in many cases in dentistry, in addition to the higher radiation and cost of

Comparison of the 3D triple-scan protocol and the impression replica technique for 3-unit tooth-supported fixed dental prostheses

Biomaterial Investigations in Dentistry, 2019
Objective: The aim of this study was to compare the fit measurements from the 3 D triple-scan protocol and the impression replica technique, by measuring the fit of three-unit tooth-supported fixed dental prostheses.

Osseointegrated prostheses for rehabilitation following amputation : The pioneering Swedish model. [PDF]

, 2017
The direct attachment of osseointegrated (OI) prostheses to the skeleton avoids the inherent problems of socket suspension. It also provides physiological weight bearing, improved range of motion in the proximal joint, as well as osseoperceptive sensory ...

Engineering the Future of Restorative Clinical Peripheral Nerve Surgery

Advanced Healthcare Materials, EarlyView.
What if damaged nerves could regenerate more effectively? This review unveils cutting‐edge strategies to restore nerve function, from biomaterial scaffolds and bioactive molecules to living engineered tissues. By accelerating axonal regrowth, preserving Schwann cells, and enhancing connectivity, these approaches are reshaping nerve repair—offering new ...
