Absolute Pitch: Theoretical Concept and Practical Issues
Bártová, Jitka ; Váňová, Hana (advisor) ; Pecháček, Stanislav (referee)
The thesis aims at complex assessment of absolute pitch both theoretically and practically. It describes the functioning of ear and main issues related to processing of sound and tone height. In addition, it clarifies related terms stemming from musical psychology. Especially, it endeavours to identify causes of absolute pitch and factors which form it. The thesis surveys several phenomena connected with absolute pitch, for example with synesthesia, and with other aspects such as occurrence of absolute pitch among population. It uses not only the Czech but especially English written literature which has not yet been used in such a scope in the Czech musical research.

Oxidative damage to proteins
Bártová, Jana ; Boušová, Iva (advisor) ; Zemanová, Lucie (referee)
Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Biochemical Sciences Candidate: Jana Bártová Supervisor: PharmDr. Iva Boušová, Ph.D. Title of diploma thesis: Oxidative damage to proteins Hypochlorous acid is a strong oxidant, which is used by phagocytic cells to kill ingested bacteria. Surrounding structures including proteins may be damaged in case the content of a phagocyte is spilled to the vicinity. Catechins belong to a group of flavonoids whose antioxidant properties were demonstrated in many studies. My diploma thesis was focused on a potential effect of eight naturally occurring derivatives of catechin towards oxidative damage of human serum albumin (HSA) by hypochlorous acid. I used two spectrophotometric (determination of carbonyl groups and chloramines) and three electrophoretic methods (native PAGE, SDS-PAGE, immunoblotting). Dependence of an antioxidant effect on its concentration (0-3 mM) was observed during determination of chloramines and obtained data were used for calculation of EC50 values of individual catechins using program GraphPad Prism. The most effective compound was catechin whose EC50 was 4.8 µM. Results suggest that antioxidant ability decreases with increasing number of hydroxyl groups in the molecule of flavonoid. Carbonyl groups are a...

Tobacco products, their composition, adverse health effects and prevention
Faustová, Lenka ; Bártová, Jiřina (advisor)
Modern time pose heavy claims to people in career as well as in personal sphere; which move towards increasing one's stress. Not anybody can bear up against stress well, therefore people often "helps" themselves by smoking tobacco. The "help" often comes to a nicotine dependency, which seemingly fights against the stress. Children start smoking sooner and sooner. The score is ill-timed knowing about health hazards and recently growing busyness of their parents who spend less time with children and education becomes ineffective. This study should help you to get compact view of tobacco problem, its impressions and incidence to organism and shows some possibilities how to give up smoking. It also affects nonsmokers preventively.
