    Opis:
    The aim of the study was the evaluation of cadmium effects on the activity of antioxidant enzymes in rat hepatocytes. The studies were conducted with isolated rat hepatocytes incubated for 1 or 2 hours in a modified (deprived of carbonates with phosphates) Williams’ E medium (MWE) in the presence of cadmium chloride (25, 50 and 200 μM). Hepatocytes incubated in the MWE medium without cadmium chloride were used as a control. The application of the modified Williams’ E medium allowed for the appearance of cadmium compounds in a soluble form that is indispensable for suitable estimation of its toxic action. There were evaluated markers of the oxidative stress such as: concentration of thiobarbiturate reactive substances (TBARS) – proportional to the level of lipid peroxidation, concentration of reduced glutathione (GSH), and the activity of antioxidant enzymes, including superoxide dismutase (SOD1 and SOD2), catalase (CAT), total glutathione peroxidase (GSHPx), selenium – dependent glutathione peroxidase (SeGSHPx), glutathione transferase (GST) and glutathione reductase (GSHR). Alterations of antioxidant enzymes activity, the level of TBARS and GSH in isolated rat hepatocytes caused by cadmium in vitro, were shown to depend on the concentration and time of exposure of cells to this metal. The increased level of TBARS and GSH was observed as well as changes in the activity of antioxidant enzymes. The activity of SOD isoenzymes and CAT was increased, whereas GSHPx and GST were decreased. These results indicate that cadmium induces oxidative stress followed by alterations in the cellular antioxidant enzyme system in isolated rat hepatocytes.

    Opis:
    Modern information management systems are often driven by workflow engines, which require an accurate, detailed, and structured process description. Instead of theoretical modelling of such processes we propose a technique which can be a connection between traditional management (organisational structure) and business process management approach. In our work we present a case study where the automatic process mining techniques are applied to administrative processes in an environment of event logs recorded by DMS. We use event log data to discover and describe the process map of the organisation and to model structured process descriptions. Our approach allows for the extraction of models based on facts and it is a direct connection between the process model and raw data generated by the organisation. Such scenario increases consistency between the mapped model and the reality of the organisation.

    Opis:
    Introduction. Dobrava-Belgrade virus (DOBV) is one of the emerging pathogens which have been reported during the last decades in Europe and have attracted the attention of researchers. The course of infection among humans may have a varied course – from the completely asymptomatic to the more severe forms, such as haemorrhagic fever with renal syndrome (HFRS). DOBV is hosted and carried by rodents like Apodemus flavicollis or A. agrarius, which occur commonly in Europe. Objective. To-date, orthohantaviruses have been reported in Poland, both in humans and animals, but detailed countryscale studies have not yet been carried out. The aim of the study was molecular characterization of a strain which was found in A. flavicollis in south-eastern Poland. Materials and method. The phylogenetic analysis of the first Dobrava-Belgrade virus found in A. flavicollis in the subcarpathian region of south-eastern Poland, presented in this study, was performed after virus proliferation in cell culture and sequencing of specific PCR products. Results. Based on genetic sequences of fragments of three segments (S, M and L), the isolated virus was assigned to the Dobrava genotype, taking into consideration the most current classification of the DOBV species. Conclusions. The Dobrava-Belgrade virus strain isolated from A. flavicollis in the subcarpathian region of south-eastern Poland, has been molecularly characterized and assigned to Dobrava genotype, thereby the occurrence of that genotype in Poland has been confirmed by molecular techniques.
