Life after Life. The Revenants in the Early Modern Period Bohemia Lands.
Chalupová, Helena ; Šedivá Koldinská, Marie (advisor) ; Mikulec, Jiří (referee)
The master's thesis deals with one of the specifics of the cultural history of the Czech lands in the Early Modern period - i. e. the general perception of the afterlife (approximately between 1500 and 1800) and revenant issues. A revenant is meant originally a human being, who, after his death, for various reasons returns to the light of the living world, with exhibits of material (revived corpses, zombies, vampires, fexts) and immaterial (spirits, white ladies, wild hunting). In this respect, the main source are Czech demonological legends. One part of the study is to evaluate the social, religious and cultural aspects that had effect on what was said above in the specific historical period. The main emphasis is placed on the individual cases of revenants in the Czech lands, preserved in historical sources, as well as comparison with the same case in other European countries. The study will also focus on the description of biographies of historical personalities, drawing conclusions about what may have caused the conviction of being revenant.

The phenomenon of persistence in bacteria - the role of toxin-antitoxin systems.
Váchal, Martin ; Lichá, Irena (advisor) ; Seydlová, Gabriela (referee)
Most bacterial species currently studied are able to generate a small fraction of heterogeneous persister cells which are tolerant to antibiotics or other antimicrobials and still genetically identical to the susceptible parental population. Bacterial persisters emerge as a result of the stochastic regulation of cellular processes. Persistence can be triggered by stressful environmental stimuli or emerge spontaneously under favourable growth conditions. According to their origin, persistent subpopulations were divided into type I and type II persisters. Many recent studies indicate that toxin-antitoxin (TA) systems increase persistence. TA systems are ubiquitous genetic elements in prokaryotes and consist of a stable toxin, inhibiting essential cellular functions in persister cells, and an unstable antitoxin, which counteracts the activity of its toxin. Overexpression of toxin parts in excess of their corresponding antitoxin leads to multidrug tolerance (MDT). This work summarizes causes of persister formation and their hypothetical survival strategies and deals primarily with TA systems, controlling bacterial persistence of model organism Escherichia coli. The emphasis is put on the description of type I TA system TisB/IstR-1, type II TA systems HipBA, RelBE, MazEF, DinJ-YafQ, MqsRA, type V TA...
