Povzetek: Seismogenic depth and seismic coupling are important inputs into seismic hazard estimates. Although the importance of seismic coupling is often overlooked, it significantly impacts seismic hazard results. We present an estimation of upper and lower seismogenic depth and expected hypocentral depth and seismic coupling in the transition zone between the Alps, Dinarides and Pannonian Basin, characterized by a complex deformation pattern, highly variable crustal thickness, and moderate seismic hazard, supporting the development of the 2021 seismic hazard model of Slovenia. The hazard model was based on three seismic source models: area source model, fault source model and smoothed seismicity (point) source model. We estimated the lower seismogenic depth using seismological and geological data and compared them. The seismological estimate was based on two regional earthquake catalogues prepared for this study. In the area source model, estimates of lower seismogenic depth from seismological data are deeper or equal to the ones derived from geological data, except in one case. In the fault source model, we analysed each fault individually and chose seismological lower depth estimates in 12 among 89 faults as more representative. The seismogenic thickness for each individual fault source was determined for seismic coupling determination. The seismic coupling was assessed by two approaches, i.e. we chose the most trusted value from the literature, and the value determined for each fault individually by using the approach based on the updated regional fault and earthquake data sets. The final estimate of seismic coupling ranges from 0.77 to 0.38. We compared the tectonic moment rate based on long-term slip rate using different values of seismic coupling with the seismic moment rate obtained from the earthquake catalogue. The analysis is done for the whole area, as well as for the individual area zones. The analysis of N–S components of estimated slip for the largest faults in the area of west Slovenia shows that the regional geological and geodetic shortening rates are comparable. The total activity rate of three global seismic source models is compared, which gives up to a 10 % difference. Our results contribute to a better understanding of the seismic activity in the region. The presented approach for seismic coupling estimation can be applied in cases where the total slip rate is given instead of its seismic part and can be used at regional or national level. The approach is also suitable for the cross-border harmonization of the European seismic hazard modelling data.

Cisplatin-induced non-convulsive posterior reversible encephalopathy syndrome in a 41-year-old woman with metastatic malignant melanoma
Janja Ocvirk, Marko Boc, Martina Reberšek, Tanja Roš-Opaškar, 2009, izvirni znanstveni članek

Povzetek: Background. Cisplatin, a widely used antineoplastic agent usually induces peripheral neuropathy, but can rarely also complicate with encephalopathy, with or without seizures. Case report. We report a case of a young patient with metastatic malignant melanoma with signs and symptoms of cisplatin-induced non-convulsive posterior reversible encephalopaty syndrome. Within the days shortly after the first cycle of cisplatin based chemotherapy the patient suffered from nausea, vomitus, headache, severe pain at the site of sub-cutaneous metastases and confusion. She later experienced somnolence, cortical blindness and aphasia, but without epileptic seizures. Conclusions. Cisplatin is an effective chemotherapeutic drug but also very toxic one and physicians using it must also be aware of possible encephalopathy.

The dimethylhydrazine induced colorectal tumours in rat - experimental colorectal carcinogenesis
Martina Perše, Anton Cerar, 2005, pregledni znanstveni članek

Povzetek: Animal models of colorectal carcinogenesis represent invaluable research tool for investigating colorectal cancer (CRC). Experimentally induced tumours in laboratory animals provide opportunity for studying certain aspects of tumoursthat cannot be effectively studied in humans. Significant information on human CRC aetiology or factors influencing it has derived from studies using dimethylhydrazine (DMH) model that is one of the experimental models appreciated for its morphological similarity to human CRC. Today, DMH model represents useful research tool for the studies of colon carcinogens and chemopreventive agents. The review offers insight into morphogenesis and genetic alterations of DMH induced colorectal epithelial tumours in rats.

Electrochemotherapy with cisplatin of breast cancer tumor modules in a male patient
Martina Reberšek, Tanja Čufer, Zvonimir Rudolf, Gregor Serša, 2000, izvirni znanstveni članek

Povzetek: Background. The metastases of breast cancer in a male patient were treated with electrochemotherapy by intratumoral injection of cisplatin. Electrochemotherapy is chemotherapy with the subsequent local application of electric pulses to the tumor nodules in order to increase drug delivery into the cells. Case report. Cutaneous metastases of breast cancer were treated with the intratumoral administration of cisplatin and by 8 electric pulses (1300 V/cm) applied a minute later to each cutaneous metastasis. The treatmentresulted in complete response of two electrochemotherapy treated cutaneous metastases and partial response of the third metastasis. In cutaneous metastases treated with intratumoral administartion of cisplatin without electric pulses, only partial response was obtained. Conclusion. This study confirms that electrochemotherapy with cisplatin is effective in the treatment of breast cancer metastases, too, as it was already proved for electrochemotherapy with bleomycin.
