Abstract: Bryophytes respond to a variety of environmental factors, including tree species composition and geological conditions, which are influenced by both natural and anthropogenic factors. Bryophytes growing on a variety of substrates were identified in ICP Forests monitoring plots in a wide range of close-to-nature managed forests, from lowland to high mountain areas in Slovenia. Based on data on tree layer composition (broadleaves vs. conifers) and on bedrock and soil type (calcareous vs. siliceous bedrock), all study plots were classified into five groups representing forest types. Different ordination analyses and statistical tests were used to represent differences between forest types in bryophyte composition, richness and functional traits. Almost 200 bryophyte species were identified in managed forests, with the most common being Hypnum cupressiforme, Brachytheciastrum velutinum and Polytrichum formosum. Bryophyte species composition varied considerably along the tree species composition and edaphic gradients represented by the selected forest types. Bryophyte species richness was significantly higher on calcareous bedrock than on siliceous bedrock. The higher occurrence of rocks on the ground surface may significantly increase the availability of various microhabitats for bryophytes. Bedrock had a significant influence on the functional diversity and composition of bryophytes, while tree species composition had less influence. Bedrock and tree species composition are important drivers of bryophyte species composition and diversity at taxonomic and functional trait levels. The high diversity of bryophyte species in Slovenian forests can also be attributed to close-to-nature and sustainable forest management practices that preserve favourable microclimatic conditions in forest stands and maintain diverse substrates.

Abstract: The effects of rapid weight loss (RWL) in combat sports athletes is an area that is not yet fully discovered. Therefore, the goal of this study was to determine the impact of weight loss on HGS (handgrip strength) in Greco-Roman wrestlers.This cross-over study included ten athletes examined for HGS during three time points for each hand. The first measurement – baseline (BL), was performed before we-ight reduction. The second measurement ‒ phase 1 (P1), was taken after high-intensity sports specific training (HISST) combined with RWL. In this phase, participants had to lose 5% of their body mass within three days, after which HISST was carried out (on day 3). The third measurement ‒ phase 2 (P2), was performed seven days after P1, which included HISST with no RWL.When comparing the HGS values, significantly higher values were observed only when P1 was compared with P2 for the left hand (p=0.039). This means that the grip was significantly stronger after RWL was conducted together with HISST.This research could be of great importance to combat sports coaches and athletes as it evaluates the effect of RWL on performance parameters. Therefore, the results of our study could serve to improve the wrestlers’ weight-reduction plan.

Abstract: Različni mehanizmi delovanja tarčnih zdravljenj in vpletanja v številne znotrajcelične signalne poti lahko vodijo v raznolike kardiovaskularne sopojave s pestro klinično sliko. Kardiovaskularni zapleti so v veliki meri reverzibilni. Med najpogostejše sopojave uvrščamo srčno popuščanje in aritmije. Pri zdravljenju s HER2 zaviralci je najpogostejši sopojav asimptomatsko znižanje iztisnega deleža levega prekata, pri zdravljenju z zaviralci angiogeneze hipertenzija. Pri zdravljenju z monotarčnimi tirozin kinaznimi inhibitorji (TKI) so kardiotoksični zapleti heterogeni. Kljub pomanjkanju enotnih smernic za obravnavo kardiotoksičnosti, si je literatura enotna, da je potrebno bolnike tekom zdravljenja skrbno spremljati, v primeru zapletov zdravljenje prekiniti in bolnike simptomatsko zdraviti.

Abstract: Sistemsko onkološko zdravljenje lahko povzroča akutno in pozno srčnožilno toksičnost, ki bistveno vpliva na kvaliteto življenja in celokupno preživetje po zaključenem zdravljenju, zato moramo pred začetkom zdravljenja oceniti tveganje za nastanek srčnožilne toksičnosti, upoštevati preventivne ukrepe in v primeru nastanka srčnožilnih zapletov hitro in ustrezno ukrepati. Najpogosteje s kardiotoksičnostjo povezujemo antracikline, ki povzročajo srčno popuščanje. Tveganje za nastanek je odvisno kumulativne doze antraciklinov, zdravljenje pa sledi splošnim smernicam zdravljenja srčnega popuščanja. Fluoupirimidini največkrat povzročajo povratno kardiotoksičnost preko vazospazma koronarnih arterij, kar vodi v relativno ishemijo miokarda. Ob tem lahko pride do netipične angine pektoris, ki se pojavi v mirovanju ali ishemičnih sprememb v EKG, oboje pa mine po prekinitvi zdravljenja. Redkeje se srečamo s kardiotoksičnostjo tudi pri drugih kemoterapevtikih.
