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

Lasers in Surgery and Medicine, Volume 58, Issue 8, Page 683-692, October 2026.
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:

The mechanism of eutectic growth in highly anisotropic materials

Nature Communications, 2016
The origins of non-periodic growth features observed in irregular eutectics have been a source of controversy. Here authors use time-resolved X-ray microtomography during eutectic growth of an alloy to show how competing models can be extended and ...

Comparison of elastic properties of periodic and aperiodic porous structures produced by additive methods

Acta Polytechnica CTU Proceedings
The aim of this work was to design, print, and examine elastic properties of porous structures with various parameters and beam distributions. These structures, generated using an algorithm, featured three types of lattices: octet, cubic, and Voronoi ...

Advanced Electron Microscopy and Microcomputed Tomography Analysis of Single‐Crystal Ni‐Base Superalloys After Short‐Term Multiaxial Creep

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
This work studies the anisotropic behavior of circular notched tensile specimens of Ni‐base superalloy single crystals during high‐temperature tensile creep along [001], [110], and [111]. Correlative scale‐bridging imaging of specimens reveals early rupture along [110] because 1) plastic deformation proceeds faster at notch center; 2) more (brittle ...

Investigating microarchitectural characteristics of woven bone exposed to ionizing radiation: comparative analysis of two segmentation methods and their impact on trabecular measurements in an animal study

Bioscience Journal
The study aimed to evaluate bone formation in surgical defects exposed to ionizing radiation (IR) and to compare two image segmentation methods: manual and standardized delimitation of the region-of-interest (ROI). Bone defects were created in the tibias
