31. Schedule-dependency of doxorubicin and vinblastine in EAT tumours in miceMarija Auersperg, Ana Pogačnik, Veronika Kloboves-Prevodnik, Gregor Serša, Maja Čemažar, 2006, original scientific article Abstract: Background. Antitumour schedule-dependency of the doxorubicin and vinblastine combination was explored. Materials and methods. Intraperitoneal Ehrlich ascites tumours (EAT) syngeneic to CBA mice were treated with vinblastine ar doxorubicin alone, or in combined treatment schedules. Results. Combinations of doxorubicin and vinblasfine administered at 48-h, but not at 24-h interval,regardless of the sequence of drugs, significantly reduced the numberof tumour cells in the ascites in corrtparison with all other treatments. In the combined treatment schedules, the predominant morphologicalchanges as well as DNA distribution pattern were dependent on thefirst drug applied. Regardless of the sequence of the drugs, median survival times of animals did not significantly differ between the treatment groups. Conclusions. The effect of combination of vinblastine and doxorubicin is schedule-dependent. The time interval, but not the sequence of drugs seems to be crucial for the observed effect. The data from preclinical studies are important for planning combined treatment schedules in clinical setting.

32. An outbreak of Verticillium dahliae on sycamore maple in a forest stand in SloveniaAna Brglez, Zina Devetak, Nikica Ogris, Sebastjan Radišek, Barbara Piškur, 2024, original scientific article Abstract: Verticillium dahliae Kleb., the causal agent of Verticillium wilts, is a devastating plant disease affecting many plant species. Fungus V. dahliae was detected in a partially artificially established Acer pseudoplatanus L. forest stand in central Slovenia. This finding incited further study about the risk of different sources of V. dahliae isolates for maples in forests and the pathogenicity of three V. dahliae isolates of different origins was tested on saplings of A. pseudoplatanus, A. platanoides L., and A. campestre L. The inoculated saplings exhibited disease symptoms, i.e., leaf necrosis and wilting. At the end of the pathogenicity test, typical xylem browning was visible on the cross-sections, and the pathogen was successfully re-isolated. The isolates showed significant differences in their pathogenicity to specific maple hosts, with the agricultural isolate (originated from bell pepper) being the most aggressive on all three maple species. The disease severity index (DSI) and relative area under the disease progress curve (rAUDPC), as well as the success of re-isolation, indicate that A. platanoides is the most susceptible to inoculation with V. dahliae. In addition, significant differences in sapling biomass were observed between treated and control plants. These results suggest that maples in forest stands are threatened by V. dahliae, and biosecurity measures should be considered and implemented in forest management to reduce the transmission and potential spread of the pathogen.

34. Patogenost izolatov izbranih vrst gliv na Pinus sylvestris L. IN P. nigra ArnoldAna Brglez, Barbara Piškur, Nikica Ogris, 2023, original scientific article Abstract: Na sadikah rdečega in črnega bora smo testirali patogenost osmih izbranih izolatov gliv (Corinectria fuckeliana, Diaporthe eres, Diplodia pinea, Fusarium sp. 1 in 2, Fusicolla sp., Nectria dematiosa in Tympanis sp.), ki smo jih izolirali iz obolelih borovih dreves v Sloveniji v letih 2020 in 2021. Inokulirali smo skupno 115 sadik borov (vključno s kontrolo), periodično smo preverjali njihovo zdravstveno stanje in ob prvih znakih sušenja opravili reizolacije iz robov nastalih nekroz. Reizolacije so bile uspešne le v primeru inokulacije z vrstami gliv Diplodia pinea, Diaporthe eres in Fusarium sp. 2. Povprečna dolžina nekroz sadik rdečega bora, inokuliranih z D. pinea, Di. eres in Tympanis sp., se je statistično značilno razlikovala od kontrolnih sadik (p < 0,05). Pri sadikah črnega bora pa so se za statistično značilne izkazale povprečne dolžine nekroz pri kontroli in inokulacijah z glivama D. pinea in Tympanis sp. (p < 0,05).

35. Factors influencing rehabilitation in patients with head and neck cancerIrena Hočevar-Boltežar, Alojz Šmid, Miha Žargi, Avgust Župevc, Igor Fajdiga, Janez Fischinger, Ana Jarc, 2000, original scientific article Abstract: Purpose. The purpose of the prospective study was to identify the factors adversely influencing the post-treatment rehabilitation in patients with head and neck cancer. Patients and methods. One hundred and ten patients with oral cavity, pharyngeal and laryngeal cancer were examined before surgical treatment in order to find unfavorable factors: hearing loss, defective teeth,impaired pulmonary function, and speech disorders. The patients evaluated the success of their rehabilitation 12 months after the treatment. The influence of possible unfavorable factors, tumor site, and type of surgeryon speech, swallowing and reintegration competence was determinated. Results. The site of the tumor and the type of surgery did not influence the quality of rehabilitation in general. Defective teeth influenced the ability of swallowing but not the speech. Hearing loss impaired the patient's reintegration in their home environment. Impaired pulmonary function did not affect patient's speech. Speech was the poorest in laryngectomized patients. However, about two thirds of the patients were satisfied with their capabilityof speech, swallowing and their rehabilitation in general. Conclusions. Early identification of unfavorable factors, and individually planned rehabilitation can ensure a suitable quality of life for patients thathave undergone surgery for head and neck cancer.
