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.

Mathematical Modeling and Biomechanical Analysis of a Derotation Plate for Treating Complex Hip Dysplasia
Published on 2025-03-10 by Durdana Oktyabrova, Kairat Ashimov, Berk Guclu, Mukhtar Abilmazhinov, Boris Gorbunov, Ramazanov Zhanatay, Timur Baidalin, Bekzhan Suleimenov, Askar Beknazarov, Bagdat Azamatov, Nail Beisekenov @MDPI
Abstract: Developmental dysplasia of the hip, particularly Crowe type IV, presents significant challenges in orthopedic surgery due to severe anatomical deformities and biomechanical instability. This study focuses on evaluating the biomechanical performance of a prosthesis–femur–derotation plate system designed to address these challenges. Using FEA, a comprehensive assessment of stress distribution, displacement, and safety factors was conducted under physiological loading co[...]
Our summary: Evaluation of a derotation plate system for treating severe hip dysplasia, using FEA to assess stress distribution and displacement, demonstrating effectiveness in stabilizing the femur and restoring limb axis, with promising biomechanical properties for improved surgical outcomes.

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.

Evaluation of the Distal Periodontal Bone Defect Associated with Lower Third Molar Extraction
Published on 2025-03-06 by Pierantonio Bellini, Shaniko Kaleci, Giacomo Setti, Sara Cavecchia, Carlotta Bellesia, Matilde Ruozzi, Ugo Consolo @MDPI
Abstract: Background: Dental impaction requires careful consideration prior to extraction. Factors influencing the decision to extract an impacted tooth include the depth of impaction, proximity to vital structures, patient age, systemic conditions, and compliance. The eruption of third molars often presents periodontal challenges for adjacent second molars, with studies identifying a link between third molar presence and periodontal defects. Orthopantomography (OPG) is the primary diagnostic tool, provid[...]

Bladder drainage and irrigation pump
Patent published on the 2025-03-06 in WO under Ref WO2025049262 by REGENTS OF THE UNIV OF MICHIGAN [US] (Sack Bryan [us], Wan Julian [us], Gao Connie [us], Gerber Benjamin [us], Pansare Ritika [us], Tatikonda Jayanth [us], Pingel Joel [us])
Abstract: A bladder drainage and irrigation pump system includes a pump subsystem, a housing subsystem, an electrical subsystem, and a user interface subsystem. The pump, which may be a peristaltic pump, actuates fluid through a length of flexible tubing in a direction away from a catheter in fluid communication with a catheter-end port, toward a drainage outlet port. A controller of the system terminates a drainage cycle once a pressure sensor detects a change in pressure indicative of the bladder being [...]
Our summary: Bladder drainage and irrigation pump system includes pump, housing, electrical, and user interface subsystems. Pump actuates fluid away from catheter towards drainage outlet port. Controller terminates drainage cycle when pressure sensor detects bladder is empty, initiates irrigation cycle. User interface separately initiates drainage and irrigation cycles.
