125. Fizikalni modeli imunoterapije in radioterapijeDamijan Valentinuzzi, Martina Vrankar, Katja Uršič Valentinuzzi, Mojca Unk, Olga Gordeeva, Alen Hadžić, Gregor Serša, Maja Čemažar, Robert Jeraj, 2023, published scientific conference contribution Abstract: V prispevku bomo predstavili rezultate fizikalnih modelov imunoterapije, ki smo jih razvili v programski skupini Medicinska fizika na Fakulteti za matematiko in fiziko Univerze v Ljubljani. Glavni cilj raziskav je bila prepoznava bioloških značilnosti tumorjev, od katerih je odvisen odziv na zdravljenje s protitelesi receptorja programirane celične smrti l (angl. anti-programmed-death-1 (anti-PD-1)). Posebno pozornost smo namenili meritvam modelskih parametrov ter preverbi rezultatov modeliranja, kar je eden izmed predpogojev za uspešno translacijo modeliranja v rutinsko predklinično in klinično prakso. Predstavili bomo tudi načrte za prihodnost, tj. modeliranje kombinacije anti-PD-1 in radioterapije.

127. Forest managers’ perspectives on environmental changes in the biosphere reserve Mura-Drava-DanubeMarcus Sallmannshofer, Rok Damjanić, Harald Vacik, Marjana Westergren, Tjaša Baloh, Gregor Božič, Mladen Ivanković, Gyula Kovács, Miran Lanšćak, Katharina Lapin, Laszlo Nagy, Silvija Krajter Ostoić, Saša Orlović, Srđan Stojnić, Peter Železnik, Milica Zlatković, Silvio Schueler, 2023, original scientific article Abstract: Riparian forests are particularly vulnerable to environmental change and anthropogenic influences because they are highly dynamic ecosystems, thus proper adaptation measures are crucial. The implementation of these measures, however, strongly depends on the actors’ perceptions of the specific problems occurring in such forests. For understanding the constraints of specific interest groups toward different adaptation activities, information in this field is essential. By conducting a questionnaire survey we explore how different types of forest managers, i.e., forestry professionals, forest owners, and conservation managers, perceive the effects of environmental change on forest management in the recently established Transboundary Biosphere Reserve Mura-Drava-Danube. We show that these forest managers are highly aware of ongoing environmental changes and appraise deteriorating forest conditions, especially after observing changes themselves. Abiotic damage is expected to increase the most, followed by biotic damage, the spread of non-native species, and tree dieback. Nearly 80% of the survey respondents expect further changes and almost all of them intend to adapt their management of forests to mitigate or prepare for these changes. Nevertheless, we show differences in sensitivity to change and willingness to initiate adaptation actions by assessing adaptation thresholds: conservation managers appear generally more tolerant to changes, which results in higher thresholds to initiate management adaptation than forestry professionals

129. Obravnava bolnic s sumom na raka telesa materniceGregor Vivod, 2023, published scientific conference contribution Abstract: Z naraščajočo incidenco raka materničnega telesa v razvitem svetu je v prihodnjih letih
ocenjeno, da bo v Sloveniji za rakom materničnega telesa zbolelo več kot 400 bolnic letno. Z
obravnavo bolnic s sumom ali že znanim rakom telesa maternice se sreča vsak ginekolog.
Začetna obravnava bolnic vključuje anamnezo (družinska, osebna, ginekološka, sedanja),
splošni klinični pregled ter ginekološki klinični pregled z vaginalnim ultrazvokom. V nadaljnji
obravnavi sledi potrditev diagnoze (histeroskopija, abrazija ali aspiracijska biopsija) ter glede
na klinično presojo ustrezna slikovna diagnostika (CT, MR, PET-CT). Stremeti moramo k
optimalni in čimprejšnji diagnostični obravnavi na primarni in sekundarni ravni ter na
učinkovitem zdravljenju (operativni poseg, obsevanje, sistemsko zdravljenje) na terciarni ravni.
Po končanem zdravljenju morajo biti vse bolnice ustrezno sledene.

130. Application of electrochemical methods for studying steel corrosion in alkali-activated materialsShishir Mundra, Gabriel Samson, Giulia Masi, Rebecca Achenbach, David M. Bastidas, Susana Bernal, Maria Chiara Bignozzi, Maria Criado, Martin Cyr, Nina Gartner, Stefanie von Greve‐Dierfeld, Andraž Legat, Nikoonasab Ali, John L. Provis, Michael Raupach, Gregor J. G. Gluth, 2023, original scientific article Abstract: Alkali‐activated materials (AAMs) are binders that can complement and partially substitute the current use of conventional cement. However, the present knowledge about how AAMs protect steel reinforcement in concrete elements is incomplete, and uncertainties exist regarding the application of electrochemical methods to investigate this issue. The present review by EFC WP11‐Task Force ‘Corrosion of steel in alkali‐activated materials’ demonstrates that important differences exist between AAMs and Portland cement, and between different classes of AAMs, which are mainly caused by differing pore solution compositions, and which affect the outcomes of electrochemical measurements. The high sulfide concentrations in blast furnace slag‐based AAMs lead to distinct anodic polarisation curves, unusually low open circuit potentials, and low polarisation resistances, which might be incorrectly interpreted as indicating active corrosion of steel reinforcement. No systematic study of the influence of the steel–concrete interface on the susceptibility of steel to corrosion in AAMs is available. Less common electrochemical methods present an opportunity for future progress in the field.
Keywords: alkali-aktivated materials, alkali‐activated materials, anodic/cathodic polarisation, concrete, linear polarisation resistance, open circuit potential, reinforcement corrosion, resistivity
