4. Decrease in cellular nanovesicles concentration in blood of athletes more than 15 hours after marathonZala Jan, Mitja Drab, Damjana Drobne, Apolonija Bedina Zavec, Mojca Benčina, Barbara Drašler, Matej Hočevar, Judita Lea Krek, Ljubiša Pađen, Manca Pajnič, Neža Repar, Boštjan Šimunič, Roman Štukelj, Veronika Kralj-Iglič, 2021, original scientific article Abstract: Introduction: Cellular nanovesicles (CNVs), that are shed from cells, have been recognized as promising indicators of health status. We analyzed the effect of long-distance running on concentration of CNVs, along with some standard blood parameters, in 27 athletes two days before and > 15 hours after physical effort. Methods: CNVs were isolated by repetitive centrifugation and washing of samples, and assessed by flow cytometry. Cholinesterase (ChE) and glutathione S-transferase (GST) activity were measured spectrophotometrically. Interleukin 6 (IL-6) and tumor necrosis factor-% (TNF-%) concentrations were measured using enzyme-linked immunosorbent assay (ELISA). C-reactive protein (CRP) was measured with immunoturbidimetric determination and lipidogram parameters were measured by enzymatic colorimetric assay. Flow cytometry was used for blood cell count and mean platelet volume (MPV) measurement. Results: More than 15 hours after physical effort a decrease was found in CNVs% concentration in isolates from blood (46%; p< 0.05), in ChE activity in whole blood (47%; p< 0.001), in plasma (34%; p< 0.01), and in erythrocyte suspension (54%; p< 0.001), as well as in GST activity in erythrocyte suspension (16%; p< 0.01) and in IL-6 concentration in plasma (63%; p< 0.05). We found no change in GST activity in plasma and in TNF-% concentration in plasma. Correlations (> 0.8; p< 0.001) between CNVs% concentration and ChE activity, and GST activity, respectively, in erythrocyte suspension were found. Conclusion: We found that > 15 hours post-physical effort, CNVs% concentration was below the initial value, concomitant with other measured parameters: ChE and GST activity as well as IL-6 concentration, indicating a favorable effect of physical effort on health status. CNVs% concentration and ChE activity in isolates from peripheral blood proved to have potential as indicators of the response of the human body to inflammation after physical effort. Physical activity should be considered as an important factor in preparation of subjects for blood sampling in procedures focusing on CNV-containing diagnostic and therapeutic compounds.

5. Tarčno zdravljenje razsejanih gastrointestinalnih stromalnih tumorjev v SlovenijiAjša Repar, Erika Matos, Branko Zakotnik, 2008, other scientific articles Abstract: Gastrointestinalni tumorji (GIST) so redke neoplazme mezenhimskega izvora, ki na celični površini izražajo transmembranski receptor KIT, produkt c-kit protoonkogena. Pri patogenezi GIST so pomembne mutacije KIT. Njihova posledica je aktivacija KIT signalne poti, ki vodi do nekontrolirane proliferacije celic in rezistenco na apoptozo. Do nedavnega je bilo radikalno kirurško zdravljenje edina uspešna oblika zdravljenja za manjše in dobro omejene GIST, za razsejano bolezen pa ni bilo uspešne terapije. Z odkritjem imatinib mesilata in kasneje sunitiniba, ki inhibirata KIT signalno pot, se je prognoza bolnikov z GIST močno izboljšala. Srednje preživetje bolnikov z razsejano boleznijo se je iz pol leta povečalo skoraj na pet let. Od leta 2001 smo na Onkološkem inštitutu Ljubljana uspešno zdravili 51 bolnikov. Srednje preživetje naših bolnikov je 66 mesecev. To lahko pripisujemo timski obravnavi bolnikov, ki je glede na velikost Slovenije in nizko incidenco GIST smiselna na enem mestu.
