Marija Đurić, Vesna Zalar Serjun, Ana Mladenovič, Alenka Mauko Pranjić, Radmila Milačič, Janez Ščančar, Janko Urbanc, Nina Mali, Alenka Sešek Pavlin, Janez Turk, Primož Oprčkal, 2023, izvirni znanstveni članek

Povzetek: The environmental properties of three geotechnical composites made by recycling wastes were investigated on a laboratory scale and in the field with the use of lysimeters designated for the revitalization of degraded mining sites. Composites were prepared by combining the mine waste with paper-mill sludge and foundry sand (Composite 1), with digestate from municipal waste and paper ash (Composite 2), and with coal ash, foundry slag and waste incineration bottom ash (Composite 3). The results of laboratory leaching tests proved that Composites 1 and 3 are envi- ronmentally acceptable, according to the legislative limits, as the potentially hazardous substances were immobilized, while in Composite 2, the legislative limits were exceeded. In the field lysimeters, the lowest rate of leaching was determined for optimally compacted Composites 1 and 3, while for Composite 2 the leaching of Cu was high. This study proved that optimally installed Composites 1 and 3 are environmentally acceptable for use in construction as an alternative to virgin materials, for the revitalization of degraded mining sites or, along with Composite 2, for closure operations with landfills. In this way, locally available waste streams are valorised and channelized into a beneficial and sustainable recycling practice.

Slikovne preiskave pri bolnikih z melanomom
Anja Meden Boltežar, Nina Boc, 2023, objavljeni znanstveni prispevek na konferenci

Povzetek: Vloga radiologije pri vseh bolnikih je najprej odkrivanje sprememb - detekcija, nato karakterizacija odkritih patoloških sprememb. Po karakterizaciji pride na vrsto ocena razširjenosti bolezni, ocena učinka terapije in po končanem zdravljenju v okviru sledenja bolnikov.

Contrasting responses of alien and ancient forest indicator plant species to fragmentation process in the temperate lowland forests
Mirjana Šipek, Lado Kutnar, Aleksander Marinšek, Nina Šajna, 2022, izvirni znanstveni članek

Povzetek: 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.

Sistemsko zdravljenje bolnikov s pljučnim rakom : zaviralci imunskih nadzornih točk
Nina Turnšek, 2023, objavljeni znanstveni prispevek na konferenci

Povzetek: 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.

Stroop in motion : neurodynamic modulation underlying interference control while sitting, standing, and walking
Manca Peskar, Nina Omejc, Maja Maša Šömen, Aleksandar Miladinović, Klaus Gramann, Uroš Marušič, 2023, izvirni znanstveni članek

Povzetek: 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.

Development of groundwater flow models for the integrated management of the alluvial aquifer systems of Dravsko polje and Ptujsko polje, Slovenia
Ada Vengust, Anja Koroša, Janko Urbanc, Nina Mali, 2023, izvirni znanstveni članek

Povzetek: 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.

Psevdoprogres : terapevtska zagata v imunoterapiji
Tadeja Skok, Nina Boc, 2023, objavljeni znanstveni prispevek na konferenci

Povzetek: 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.
