1. ReSurveyEurope : a database of resurveyed vegetation plots in EuropeIlona Knollová, Milan Chytrý, Helge Bruelheide, Stefan Dullinger, Ute Jandt, Markus Bernhardt-Römermann, Idoia Biurrun, Francesco de Bello, Michael Glaser, Stephan M. Hennekens, Mateja Germ, Aleksandra Golob, Janez Kermavnar, Lado Kutnar, Urban Šilc, 2024, pregledni znanstveni članek Povzetek: Aims We introduce ReSurveyEurope — a new data source of resurveyed vegetation plots in Europe, compiled by a collaborative network of vegetation scientists. We describe the scope of this initiative, provide an overview of currently available data, governance, data contribution rules, and accessibility. In addition, we outline further steps, including potential research questions. Results ReSurveyEurope includes resurveyed vegetation plots from all habitats. Version 1.0 of ReSurveyEurope contains 283,135 observations (i.e., individual surveys of each plot) from 79,190 plots sampled in 449 independent resurvey projects. Of these, 62,139 (78%) are permanent plots, that is, marked in situ, or located with GPS, which allow for high spatial accuracy in resurvey. The remaining 17,051 (22%) plots are from studies in which plots from the initial survey could not be exactly relocated. Four data sets, which together account for 28,470 (36%) plots, provide only presence/absence information on plant species, while the remaining 50,720 (64%) plots contain abundance information (e.g., percentage cover or cover–abundance classes such as variants of the Braun-Blanquet scale). The oldest plots were sampled in 1911 in the Swiss Alps, while most plots were sampled between 1950 and 2020. Conclusions ReSurveyEurope is a new resource to address a wide range of research questions on fine-scale changes in European vegetation. The initiative is devoted to an inclusive and transparent governance and data usage approach, based on slightly adapted rules of the well-established European Vegetation Archive (EVA). ReSurveyEurope data are ready for use, and proposals for analyses of the data set can be submitted at any time to the coordinators. Still, further data contributions are highly welcome.

4. Safety and efficacy of IL-12 plasmid DNA transfection into pig skin : supportive data for human clinical trials on gene therapy and vaccinationUrša Lampreht Tratar, Tanja Jesenko, Maša Omerzel, Alenka Seliškar, Urban Stupan, Mihajlo Djokić, Jerneja Sredenšek, Blaž Trotovšek, Gregor Serša, Maja Čemažar, 2024, izvirni znanstveni članek Povzetek: Gene electrotransfer (GET) of plasmids encoding interleukin 12 (IL-12) has already been used for the treatment of various types of tumors in human oncology and as an adjuvant in DNA vaccines. In recent years, we have developed a plasmid encoding human IL-12 (phIL12) that is currently in a phase I clinical study. The aim was to confirm the results of a non-clinical study in mice on pharmacokinetic characteristics and safety in a porcine model that better resembled human skin. The GET of phIL12 in the skin was performed on nine pigs using different concentrations of plasmid phIL12 and invasive (needle) or noninvasive (plate) types of electrodes. The results of our study demonstrate that the GET of phIL-12 with needle electrodes induced the highest expression of IL-12 at the protein level on day 7 after the procedure. The plasmid was distributed to all tested organs; however, its amount decreased over time and was at a minimum 28 days after GET. Based on plasmid copy number and expression results, together with blood analysis, we showed that IL-12 GET is safe in a porcine animal model. Furthermore, we demonstrated that pigs are a valuable model for human gene therapy safety studies.

7. Kompoziti iz skorje: nova gozdarsko-lesarska vrednostna verigaSergej Medved, Grega Vilman, Urban Tajher, Mark Sever, Alan Antonović, 2023, izvirni znanstveni članek Povzetek: Skorja je večopravilni (večfunkcijski) material, saj deluje kot zaščita (pred fizikalnimi in mehanskimi poškodbami, pa tudi pred biološko razgradnjo), omogoča transport vode in plinov, občasno pomaga pri fotosintezi in nudi podporo drevesu. Skorje je od 10 % do 20 % celotne mase drevesa, vendar je znaten delež ostane neizkoriščen. Da bi prikazali možnosti rabe skorje za izdelavo različnih kompozitov, smo izdelali in analizirali tri različne kompozite, in sicer lesno-plastični kompozit iz skorje in polietilena, trislojni ploščni kompozit iz skorje, zlepljene z melamin-urea-formaldehidnim lepilom, in enoslojni ploščni kompozit iz vlažnih iveri skorje, zlepljenih s taninskimi lepili.
Ključne besede: skorja, iveri, lesno plastični kompozit, iverna plošča

10. Evaluation of water equivalency of Plastic waterTM for high-energy electron beams using IAEA TRS-398 code of practiceBožidar Casar, Urban Zdešar, Vlado Robar, 2004, izvirni znanstveni članek Povzetek: Electrochemotherapy (ECT) is a novel method for efficient tumor treatment in clinical environment. It combines local drug delivery and application of shorthigh voltage pulses, which permeabilize the plasma membrane by electroporation. Drug can enter only the cells with permeabilzed membrane. Recently, medical device CliniporatorTM for controlled electroporation was developed. Here, we present a web-application that extends the functionality of this medical device. The aim of the application is to collect, store and toallow the analysis of every ECT application using this medical device. The application helps transferring data collected by dev;ce during the electroporation process to the central database, and enables filling of medical records through the web forms. The application is based on technologies ASP, HTML, Flash, JavaScript, XML and others. The application main advantages are easy and rapid data access, scalability and independence of client computer operating system as well as easy application debugging and upgrading.
