Antimicrobial Photodynamic Therapy Associated With Systemic Treatment in Osteoradionecrosis: An In Vivo Study

Lasers in Surgery and Medicine, EarlyView.
ABSTRACT Objective To evaluate the effects of antimicrobial photodynamic therapy (aPDT), systemic pharmacological therapy, and their combination on irradiated mandibular post‐extraction bone repair relevant to osteoradionecrosis (ORN) development in a rat model. Methods Twenty‐six male Wistar rats were initially randomized into five experimental groups:

Crystallinity, Porosity, and Microstructure of Polyphenylene Sulfide Composite Parts Fabricated by Filament‐Extrusion Additive Manufacturing

Polymer Composites, EarlyView.
High‐performance PPS composites for FFF: formulation and characterization linking microstructure and crystallization to adhesion and mechanical properties. ABSTRACT Polyphenylene sulfide (PPS) was compounded with recycled carbon fibers (rCF) and thermal black (TB) particles, followed by injection molding (IM) and extrusion of the compounded composites ...

Technique for bone volume measurement from human femur head samples by classification of micro-CT image histograms

Annali dell'Istituto Superiore di Sanità, 2013
INTRODUCTION: Micro-CT analysis is a powerful technique for a non-invasive evaluation of the morphometric parameters of trabecular bone samples. This elaboration requires a previous binarization of the images. A problem which arises from the binarization

Analyzing the compressive behavior of porous Ti6Al4V by X-ray microtomography [PDF]

Materials Research, 2017
Samples with 40% vol. of pores and a pore size distribution between 100 and 500 µm were produced by powder metallurgy from Ti6Al4V alloy powders. Sintering was performed at 1300 °C during one hour in an inert Argon atmosphere in a vertical dilatometer ...

Imaging Methods for Analyzing Adhesion in Extrusion Coating

Surface and Interface Analysis, EarlyView.
ABSTRACT Extrusion coating is a common method to produce materials for the packaging industry. One of the most important properties in extrusion‐coated structures is adhesion between the substrate and the coating. Analyzing adhesion of samples produced by extrusion coating in a standardized way can be challenging, and especially, quantitative data are ...

Integration of Micro‐CT and XRF Mapping for Multimodal 3D Analysis of Polychrome Wooden Artifacts

X-Ray Spectrometry, EarlyView.
ABSTRACT Over the past 5 years, computer applications have become crucial to archeological research. Since the 1990s, the focus has transitioned from data management tools to the development of virtual models. Recently, digital documentation of cultural heritage has gained considerable focus, with 3D modeling of objects.

Paired CycleGAN‐based virtual staining for 3D X‐ray histology of bone‐implant systems

Journal of Synchrotron Radiation, EarlyView.
This work demonstrates virtual staining for 3D X‐ray histology using a modified CycleGAN trained on paired synchrotron radiation microtomography (SR‐µCT) and histology images of bone‐implant specimens. The method enables the generation of artificially coloured contrast resembling conventional histological staining from label‐free SR‐µCT data and is ...

Phase-contrast microtomography of thin biomaterials

Journal of Materials Science: Materials in Medicine, 2004
Phase-contrast microtomography, performed at the beamline ID 22 of the European Synchrotron Radiation Facility (ESRF, Grenoble, France), is demonstrated for high-resolution 3-D imaging of a hydroxyapatite sample. The technique, which relies on phase contrast imaging, gives the possibility to observe features inside samples with negligible absorption ...
