Povzetek: 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.

Povzetek: Stereotaktično obsevanje, tehnika obsevanja, s katero dovedemo visoko obsevalno dozo na manjšo tarčo kjerkoli v telesu, predstavlja eno izmed možnosti radikalnega zdravljenja nekaterih tumorjev, zasevkov ali celo benignih stanj. Stereotaktično obsevanje je neinvazivno, stroški zdravljenja so nizki, bolnikom omogoča hitrejšo vrnitev v domače oziroma delovno okolje, ne poslabša kvalitete življenja in ima nizko stopnjo akutne morbiditete in mortalitete. V skrbnih radioterapevtskih postopkih, od izbora primernih bolnikov za stereotaktično obsevanje, priprave na obsevanje in izdelave obsevalnega načrta, kontrole kvalitete obsevanja, izvedbe obsevanja na linearnem pospeševalniku ter bolnikove oskrbe, sodelujemo zdravniki onkologi radioterapevti, radiologi, medicinski fiziki, dozimetristi, radiološki inženirji, medicinske sestre in zdravstveni tehniki. Skupen cilj naše timske obravnave in naporov medicinskega osebja je predvsem izboljšanje rezultatov zdravljenja ter ohranitev oziroma izboljšanje kvalitete življenja vsakega posameznega bolnika. Veliko pozornosti posvečamu tudi zmanjševanju tveganja za pojav kratkoročnih ali dolgoročnih neželenih učinkov stereotaktičnega obsevanja.

Povzetek: The trees and forests of Europe are increasingly under threat from new pests and diseases that have originated in other parts of the world. Early detection of alien species when they first appear in European countries allows rapid response and offers the best chance to mitigate against their establishment and spread. Citizen science initiatives such as LIFE ARTEMIS in Slovenia, and Observatree in the UK, provide members of the public with the necessary training and educational resource to identify these tree pests and diseases and report them to the appropriate authorities, thereby increasing the level of surveillance and the capacity of the early warning system. This paper summarises some of the outcomes of these two projects and how they have both become integral parts of the official forest and tree health monitoring systems within their respective countries of Slovenia and the United Kingdom.
