Evaluation of Osteoblast-like Cell Proliferation and Osteogenic Response
Published on 2025-03-11 by Roberto Campagna, Valentina Schiavoni, Loredana Rao, Fabrizio Bambini, Andrea Frontini, Francesco Sampalmieri, Eleonora Salvolini, Lucia Mem� @MDPI
Abstract: Nowadays, custom-made subperiosteal implants are emerging as a solution in all those cases where there is lack of healthy bone tissue to support endosseous implants. The development of innovative techniques has allowed the production of grids that precisely match the patient’s anatomy. Elucidating the impact of laser-melted Ti6Al4V grids on both hard and soft tissues with which they come into contact is, therefore, mandatory. In this study, we analyzed the effects of five different[...]
Our summary: Evaluation of the impact of laser-melted Ti6Al4V grids on osteoblast-like cell proliferation and osteogenic response, analysis of five different surface treatments on MG-63 cell line, demonstration of enhanced osteogenesis with Al Ti color surface treatment.

Parathyroid Gland Detection Based on Multi-Scale Weighted Fusion Attention Mechanism
Published on 2025-03-10 by Wanling Liu, Wenhuan Lu, Yijian Li, Fei Chen, Fan Jiang, Jianguo Wei, Bo Wang, Wenxin Zhao @MDPI
Abstract: While deep learning techniques, such as Convolutional neural networks (CNNs), show significant potential in medical applications, real-time detection of parathyroid glands (PGs) during complex surgeries remains insufficiently explored, posing challenges for surgical accuracy and outcomes. Previous studies highlight the importance of leveraging prior knowledge, such as shape, for feature extraction in detection tasks. However, they fail to address the critical multi-scale variability of PG object[...]
Our summary: Proposed framework for accurate and efficient detection of parathyroid glands using multi-scale weighted fusion and attention mechanism. Superiority demonstrated through extensive experiments on parathyroid dataset.

Fabrication of TiO2 Nanotube Arrays by Progressive Anodization of Ti Thin Film on Insulated Substrates
Published on 2025-03-09 by Chao-Ching Chiang, Jian-Sian Li, Hsiao-Hsuan Wan, Fan Ren, Josephine F. Esquivel-Upshaw @MDPI
Abstract: Titanium (Ti) thin films deposited on insulated substrates were progressively anodized and formed titanium dioxide (TiO2) nanotube arrays on the surface through a customized anodization tool designed to improve the uniformity and diameters of the nanotubes. With a motorized vertical moving arm attached to the anode, the sample was gradually submerged into the electrolyte at a controlled speed alongside the continuous anodization from the edge to the center to prevent the discontinuation of the c[...]
Our summary: Fabrication of TiO2 Nanotube Arrays by Progressive Anodization of Ti Thin Film on Insulated Substrates. Titanium thin films on insulated substrates were anodized to form TiO2 nanotube arrays using a customized tool. SEM analysis showed that optimized conditions result in uniform nanotubes for practical applications.

Fabrication of Radiopaque, Drug-Loaded Resorbable Polymer for Medical Device Development
Published on 2025-03-07 by Sophie T. Melancon, Erin Marie San Valentin, Dominic Karl M. Bolinas, Marvin R. Bernardino, Archana Mishra, Gino Canlas, Gouthami Chintalapani, Megan C. Jacobsen, Allan John R. Barcena, Steven Y. Huang @MDPI
Abstract: Resorbable medical devices provide temporary functionality before degrading into safe byproducts. One application is absorbable inferior vena cava filters (IVCFs), which prevent pulmonary embolism in high-risk patients with contraindications to anticoagulants. However, current absorbable IVCFs are limited by radiolucency and local clot formation risks. This study aimed to develop radiopaque, drug-loaded resorbable IVCFs with enhanced imaging and therapeutic capabilities. Poly-p-dioxanone (PPDO) [...]
Our summary: Development of radiopaque, drug-loaded resorbable IVCFs with enhanced imaging and therapeutic capabilities for preventing pulmonary embolism in high-risk patients. Enhanced radiopacity and anti-thrombotic potential without compromising mechanical strength or safety.

Abstract: Neodymium iron boron (NdFeB) magnetic materials are widely used in fields such as electronics, medical devices, power machinery, and hardware machinery. This paper conducted a three-factor and five-level orthogonal experiment on diamond wire saw cutting NdFeB to determine the influence degree of key factors such as workpiece feed rate, diamond wire speed, and workpiece processed size on the surface roughness Ra and waviness Wa of NdFeB slices. Further analysis was conducted on the influence of v[...]
Our summary: This study analyzed the impact of workpiece feed rate, wire speed, and workpiece size on the surface roughness and waviness of NdFeB slices through an orthogonal experiment. The optimal parameters resulted in a surface roughness Ra of 0.433 μm and waviness Wa of 0.037 μm, with a regression model established for waviness PV value.
