1. Circulating serum sVCAM-1 concentration inadvanced ovarian cancer patients : correlation with concentration in ascitesMarina Jakimovska, Katarina Černe, Ivan Verdenik, Borut Kobal, 2014, original scientific article Abstract: Background. Vascular cell adhesion molecule-1 (VCAM-1) is associated with ovarian cancer progression but theorigin of its soluble form (sVCAM-1) in serum is not well investigated. The purpose of this study was to elucidate whetherthe concentration of sVCAM-1 in serum correlates with the concentration in ascites, that represents local tumour environment,and with systemic inflammation, various clinicopathological characteristics, and patient outcome.Patients and methods. Thirty-six patients with advanced ovarian cancer were included in the study. Serum forsVCAM-1 analysis was obtained prior to surgery. Ascites samples were collected at the beginning of the operation.Clinical data were collected from patients medical records. sVCAM-1 in samples was analysed by flow cytometricbead-based assay. The mean follow-up period was 11 months (range 0-23) from the time of surgery.Results. Serum sVCAM-1 concentrations are positively correlated to ascites sVCAM-1 concentrations. There was aweakly positive correlation of serum sVCAM-1 with tumour size and no correlation with inflammatory tumour markers,FIGO stage or grade. Higher concentrations of sVCAM-1 were associated with poor disease outcome (death fromovarian cancer) in almost all cases before chemotherapy was started.Conclusion. This is the first study demonstrating that serum concentrations of sVCAM-1 in advanced ovarian cancerpatients correlate with sVCAM-1 concentrations in ascites, thus expressing the biologic potential of malignant diseaseto metastasis, rather than systemic inflammation. Higher serum and ascites sVCAM-1 concentrations might have predictivepotential for different biologic behaviour.

2. Morphological and molecular characterization of Micromeria croatica (Lamiaceae), an endemic and potentially valuable horticultural species of the Dinaric AlpsZlatko Liber, Ivan Radosavljević, Zlatko Šatović, Marija Hodja, Vesna Židovec, Faruk Bogunić, Dalibor Ballian, Danijela Stešević, Sven D. Jelaska, Dario Kremer, 2023, original scientific article Abstract: Due to climate extremes and limited natural resources, especially water, we can expect increased demand in the future for species that can better tolerate climate extremes such as drought. One potentially valuable horticultural species is the endemic species of the Dinaride Mountains Micromeria croatica (Pers.) Schott (family Lamiaceae). It grows in the crevices of carbonate rocks, extending from an altitude of 150 m to more than 2000 m. This study aims to provide additional insight into the genetic and morphological diversity of this endemic species, focusing on valuable horticultural traits. To achieve this goal, morphological and molecular analyses were performed on ten natural populations. Through STRUCTURE and PCoA analyses, ten M. croatica populations were placed into western and eastern genetic groups, with several individuals from western populations assigned to the eastern group and vice versa. These atypical individuals assigned to the new genetic group by BAPS analysis indicate gene flow between western and eastern populations. Similarly, an analysis of molecular variance revealed fewer genetic differences than within studied populations. Both PCA and CANDISC analysis based on eleven morphological traits largely confirmed the existence of two slightly different genetic groups. Two populations containing plants with the most flowers per shoot, one with white-flowered individuals, one with the roundest leaves, and one with the narrowest leaves proved to be the most horticulturally valuable. The genetic and morphological variability found should be a sufficient basis for the potential selection of M. croatica populations and individuals for horticultural purposes.

4. A web-application that extends functionality of medical device for tumor treatment by means of electrochemotherapyIvan Pavlović, Peter Kramar, Selma Čorović, David Cukjati, Damijan Miklavčič, 2004, original scientific article Abstract: Electrochemotherapy (ECT) is a novel method for efficient tumor treatment in clinical environment. It combines local drug delivery and application of shorthigh voltage pulses, which permeabilize the plasma membrane by electroporation. Drug can enter only the cells with permeabilzed membrane. Recently, medical device CliniporatorTM for controlled electroporation was developed. Here, we present a web-application that extends the functionality of this medical device. The aim of the application is to collect, store and toallow the analysis of every ECT application using this medical device. The application helps transferring data collected by devčce during the electroporation process to the central database, and enables filling of medical records through the web forms. The application is based on technologies ASP, HTML, Flash, JavaScript, XML and others. The application main advantages are easy and rapid data access, scalability and independence of client computer operating system as well as easy application debugging and upgrading.
