51. Contrasting responses of alien and ancient forest indicator plant species to fragmentation process in the temperate lowland forestsMirjana Šipek, Lado Kutnar, Aleksander Marinšek, Nina Šajna, 2022, original scientific article Abstract: Fragmentation is one of the major threats to biodiversity. In a fragmented landscape, forest specialists are losing suitable forest habitats with specific site and microclimate conditions, which results in their local extinction. Conversely, the invasion of alien species is facilitated by open forest areas and increased boundaries between forest fragments and adjacent land. We studied the effect of fragmentation in terms of fragment size impact on overall plant species richness and on selected ecologically important groups' richness, composition, and diversity. We surveyed vegetation in the interior of 47 fragments of various sizes and one unfragmented reference forest. Our results reveal that the effect of fragmentation is complex and differs for studied plant groups. Decreasing fragment size negatively affects the overall plant richness and richness of native and ancient forest indicator plants as well as their diversity, while the effect is positive for alien plants. The highest proportion of ancient forest indicator plant species and the lowest proportion of alien plants in the unfragmented forest underline the great conservation value of forest fragments. At the same time, our results reveal that large and diverse forest ecosystems are susceptible to biological invasions as well.

52. Sistemsko zdravljenje bolnikov s pljučnim rakom : zaviralci imunskih nadzornih točkNina Turnšek, 2023, published scientific conference contribution Abstract: Zaviralci imunskih nadzornih točk (ZINT) predstavljajo pravo revolucijo v sistemskem
zdravljenju raka pljuč in so v zadnjem desetletju korenito spremenili standardno zdravljenje
teh bolnikov. Prepričljivo dobrobit s podaljšanjem preživetja so sprva izkazali kot samostojno
zdravljenje pri bolnikih z razsejanim nedrobnoceličnim rakom pljuč (NDRP), ki je napredoval
po predhodnem zdravljenju s kemoterapijo na osnovi platine. Kmalu zatem je sledil njihov
premik v prvi red zdravljenja razsejane bolezni najprej kot samostojno zdravljenje, nato pa
še v kombinaciji s kemoterapijo na osnovi platine in tudi kot kombinirana imunoterapija
dveh ZINT. Korenito so spremenili tudi obravnavo bolnikov z NDRP v zgodnejših stadijih
bolezni, predvsem lokalno napredovale oblike, še posebej veliko obetajo v perioperativnem
obdobju. Imunoterapija z ZINT se pri raku pljuč uporablja kot monoterapija, kot kombinacija
s kemoterapijo z ali brez zaviralca angiogeneze oziroma kombinacija dveh različnih ZINT.

54. Stroop in motion : neurodynamic modulation underlying interference control while sitting, standing, and walkingManca Peskar, Nina Omejc, Maja Maša Šömen, Aleksandar Miladinović, Klaus Gramann, Uroš Marušič, 2023, original scientific article Abstract: There is conflicting evidence about how interference control in healthy adults is affected by walking as compared to standing or sitting. Although the Stroop paradigm is one of the best-studied paradigms to investigate interference control, the neurodynamics associated with the Stroop task during walking have never been studied. We investigated three Stroop tasks using variants with increasing interference levels – word-reading, ink-naming, and the switching of the two tasks, combined in a systematic dual-tasking fashion with three motor conditions – sitting, standing, and treadmill walking. Neurodynamics underlying interference control were recorded using the electroencephalogram. Worsened performance was observed for the incongruent compared to congruent trials and for the switching Stroop compared to the other two variants. The early frontocentral event-related potentials (ERPs) associated with executive functions (P2, N2) differentially signaled posture-related workloads, while the later stages of information processing indexed faster interference suppression and response selection in walking compared to static conditions. The early P2 and N2 components as well as frontocentral Theta and parietal Alpha power were sensitive to increasing workloads on the motor and cognitive systems. The distinction between the type of load (motor and cognitive) became evident only in the later posterior ERP components in which the amplitude non-uniformly reflected the relative attentional demand of a task. Our data suggest that walking might facilitate selective attention and interference control in healthy adults. Existing interpretations of ERP components recorded in stationary settings should be considered with care as they might not be directly transferable to mobile settings.

55. Development of groundwater flow models for the integrated management of the alluvial aquifer systems of Dravsko polje and Ptujsko polje, SloveniaAda Vengust, Anja Koroša, Janko Urbanc, Nina Mali, 2023, original scientific article Abstract: With increasing exploitation of groundwater resources and implementation of various activities in their recharge areas, it is vital to conduct a comprehensive assessment of aquifers to ensure their conservation and sustainable management. In the present study, we used a comprehensive approach to conceptualise and identify the functioning of two connected aquifer systems in north-eastern Slovenia: the Quaternary porous aquifers Dravsko polje and Ptujsko polje. The study presents the conceptual models of both aquifers and their interconnectedness using separate mathematical-numerical models with the aim of ensuring an integrated management of these alluvial aquifer systems. It also highlights the importance of understanding connections between such systems for simulating groundwater flow and transport of different contaminants.

56. Psevdoprogres : terapevtska zagata v imunoterapijiTadeja Skok, Nina Boc, 2023, published scientific conference contribution Abstract: Sistemsko zdravljenje z imunoterapijo je v klinično prakso prineslo nove, atipične vzorce odgovorov solidnih tumorjev na zdravljenje ter tako vplivalo na radiološko oceno odgovora na terapijo. Psevdoprogres je opredeljen kot začetno povečanje bremena bolezni s kasnejšim zmanjšanjem. Pri hiperprogresu pride do hitrega povečanja tumorskega bremena, pogosto v povezavi s kliničnim poslabšanjem. Trenutno najbolj uporabljeni iRECIST kriteriji za oceno učinka imunoterapije so bili objavljeni leta 2017 ter temeljijo na osnovi kriterijev RECIST 1.1. Najpomembnejša razlika med osnovnimi RECIST kriteriji ter iRECIST kriteriji je uvedba dodatnih kontrolnih preiskav za potrditev napredovanja bolezni.
