Study of the effect of zinc oxide nanoparticles on cell migration
Kutějová, Monika ; Zumberg, Inna (referee) ; Chmelíková, Larisa (advisor)
Zinc oxide nanoparticles (ZnO NPs) are widely used across various industries due to their properties, and with the development of nanomaterials, they are also finding applications in medicine. This bachelor’s thesis investigates the cytotoxic effects of these nanoparticles on cultured cell lines. The study focused on the human osteosarcoma cell line Saos-2 and the fibroblast cell line NIH-3T3. During in vitro experiments, the cells were exposed to different concentrations of ZnO NPs. The cytotoxicity of each concentration was assessed using the MTT assay, which provided information on cell viability. Based on the MTT assay results, appropriate concentrations of ZnO NPs were selected for conducting a Scratch assay, with the highest concentration corresponding to the determined inhibitory concentration for NIH-3T3. The cytotoxic effects were thus evaluated by studying cell migration. Subsequent statistical analysis determined the extent of cytotoxic effects of ZnO NPs depending on the concentration and cell type.
Ruská propaganda v českých médiích
Kutějová, Monika
The main aim of this bachelor thesis is to verify the truth of claims about the existence of Russian disinformation campaign in selected Czech media. The thesis explores methods and tools used in the prosecution disinformation campaign in the Czech Republic, analyses the selected servers in terms of their ownership structure, transparency, and financing, as well as their manipulative techniques. As a counterpart, a chapter is outlined with institutions opposed to the Russian information war in the Czech Republic.
