52. Antifungal effect of polymethyl methacrylate resin base with embedded Au nanoparticlesIvan Marić, Anamarija Zore, Franc Rojko, Andrijana Sever Škapin, Roman Štukelj, Aleksander Učakar, Rajko Vidrih, Valentina Veselinović, Marijan Gotić, Klemen Bohinc, 2023, original scientific article Abstract: Full and partial restorations in dentistry must replicate the characteristics of the patient’s natural teeth. Materials must have good mechanical properties and be non-toxic and biocompatible. Microbes, which can form biofilms, are constantly in contact with restorations. In this study, we investigate how well Candida albicans adheres to a polymethyl methacrylate (PMMA) resin base with gold (Au) nanoparticles. We synthesized Au nanoparticles and characterized them. The average size of Au nanoparticles embedded in PMMA was 11 nm. The color difference ∆E between PMMA and PMMA/Au composites was 2.7 and was still esthetically acceptable to patients. PMMA/Au surfaces are rougher and more hydrophilic than pure PMMA surfaces, and the isoelectric point of both types of surfaces was 4.3. Above the isoelectric point, PMMA/Au surfaces are more negatively charged than PMMA surfaces. The added Au nanoparticles decreased the tensile strength, while the hardness did not change significantly. Adhesion measurements showed that PMMA surfaces modified with Au nanoparticles reduced the extent of microbial adhesion of Candida albicans.

56. Visokodozno obsevanje z ogljikovimi ioni pri bolniku z inoperabilnim recidivom karcinoma danke : prikaz primeraFranc Anderluh, Marko Boc, 2022, published scientific conference contribution Abstract: V prispevku je prikazan klinični primer bolnika z inoperabilnim recidivom karcinoma danke, ki je bil zdravljen z visokodoznim obsevanjem z ogljikovimi ioni v protonskem centru v tujini. Obsevanja s protoni ali težkimi ioni v Sloveniji zaenkrat še ne moremo zagotoviti, zato moramo vse bolnike za katere presodimo, da bi imeli od tovrstnega zdravljenja korist, napotiti na zdravljenje v enega od protonskih centrov v tujini. V primerjavi z obsevanjem s fotoni, lahko zaradi specifičnih fizikalnih lastnosti protonskih delcev in težkih ionov, pri obsevanju z njimi bistveno zmanjšamo volumne v obsevalna polja zajetih zdravih tkiv, v določenih kliničnih situacijah pa tumorje tudi obsevamo z višjimi dozami.
