Analysis of active substances and biological effects of some non-tradizional cereals
Pecháček, Michal ; Vysoká, Marie (referee) ; Márová, Ivana (advisor)
This thesis deals with the characterization of active substances and biological effects of non-traditional cereals. Basic substances of these non-traditional cereals such as carbohydrates or proteins are characterized in this work. Active compounds such as antioxidants, polyphenols or -glucans are also characterized. These substances were mainly analysed by spectrophotometric methods. The theoretical part describes cereals in general. It focuses on grain morphology, cereal products and mostly on chemical composition. The summary of substances appearing in the cereal grain such as carbohydrates, proteins, vitamins, minerals etc. was processed in this part. In the practical part, the samples of the non-traditional cereals such as amaranth, sorghum, millet, kamut, buckwheat, quinoa, Job’s tears and teff were analysed. Amaranth, millet and buckwheat were also analysed in the form of flakes. Teff was analysed only in the form of flakes. Sorghum and quinoa were analysed also in their coloured variations. Firstly, the water extracts were prepared, then they were used for determination of antioxidant activity, the content of polyphenols compounds and flavonoids. The hydrolysed samples were used for determination of the carbohydrates. For other basic analysis, samples were used in the form of powder. Best results were measured for quinoa, amaranth and buckwheat. Besides basic analysis, the content of -glucans was measured. However, the content of -glucans in these non-traditional cereals was very low. Selected cereals were tested for cytotoxicity on human cells. Cytotoxicity was evaluated by using the MTT cytotoxicity test on human keratinocytes HaCaT and human caucasian colon adenocarcinoma CaCO-2. The sensory analysis was carried out in the last part of the thesis. There were tested 6 samples. From these samples were made muffins that were analysed and sensorically evaluated.

Radioactive Waste in Hospital Facilities
Bradáč, Antonín ; Houdková, Lucie (referee) ; Tabasová, Andrea (advisor)
The thesis is focused on a little-known issue of institutional waste produced by hospitals, the creation, collection and subsequent disposal. This thesis described the distribution of waste from various aspects, especially the characteristics and their subsequent use in the effective elimination. This thesis deals with not only this issue, but trying to get closer to negative impact of ionizing radiation on the human body, not only in the current level of radiation protection, but also in terms of the historical development of different sources and work with them, especially in connection with the use of ionizing radiation in normal human activity but also through the list of nuclear accidents. The practical part of this thesis compares the three types of hospitals primarily on the basis of a personal meeting with the heads of various departments involved in the management of institutional waste, and materials derived their visit. Specifically, the hospital Atlas and Tomas Bata Regional Hospital (both situated in Zlin) and specialized workplace Masaryk cancer institute in Brno.

Systems for Generation of Pulse Magnetic Vector Potential
Hanák, Pavel ; Makáň,, Florian (referee) ; Bartušek, Karel (referee) ; Vrba, Kamil (advisor)
The doctoral thesis is focused on research, design, implementation and testing of systems for the application of magnetic vector potential to biological materials. The main objective was to analyze and design systems which could generate magnetic vector potential without the presence of other unwanted fields or at least amplify its intensity. Moreover, the systems designed had to eliminate other foreign effects on the biological samples, especially the influence of waste heat from the coils. Toroidal coils were employed to generate the vector potential, because they confine the unwanted magnetic induction inside their core thanks to their shape. The thesis employed coils with two different outer diameters, specifically 102 and 600 mm. To excite the coils, four current pulse generators capable of delivering currents of up to 100 A were constructed. The systems’ generated fields were comprehensively analyzed with the help of finite-element simulations in ANSYS. To simplify the design phase, analytical equations for the calculation of vector potential intensity at an arbitrary point around the toroidal coils were also derived. A method employing electromagnetic shielding made of two different materials was developed to suppress the unwanted fields. To eliminate the influence of heat, the 102 mm system employed air cooling and the 600 mm system employed a closed water loop to equalize the temperatures of biological samples. The biological effects of both systems were tested on genetically modified bio-luminescent bacteria Escherichia coli K12 luxABCDEamp. The thesis was created in connection with the research project of The Ministry of Education, Youth and Sports of the Czech Republic named “Research into the effect of a combination of substances for targeted therapy and inhibitory action of the field pulse vector magnetic potential on oncogenous diseases”, No. 2B08063.

Constituents of Rosmarinus officinalis and their biological effects
Klížová, Aneta ; Karlíčková, Jana (advisor) ; Tůmová, Lenka (referee)
CHARLES UVIVERSITY THE FACULTY OF PHARMACY IN HRADEC KRÁLOVÉ DEPARTMENT OF PHARMACOGNOSY AND PHARMACEUTICAL BOTANY Title of the diploma thesis: CONSTITUENTS OF ROSEMARY AND THEIR BIOLOGICAL EFFECTS Candidate: Aneta Klížová Supervisor: PharmDr. Jana Karlíčková, Ph.D. Diploma thesis 2021/2022, pp. 89 Rosemary (Rosmarinus officinalis L.) belongs to the Lamiaceae family. It is a bushy, evergreen perennial plant coming from the Mediterranean. Two pharmacopoeia herbal substances are used from this plant - leaves and essential oil. Rosemary has a wide range of uses. It is mainly used as a spice in the kitchen. Due to its antioxidant effects, it is used as a food preservative. It is also added to various cosmetic products such as soaps, creams, shampoos and perfumes. Rosemary and its components (carnosol, carnosic acid and rosmarinic acid and others) show many effects, which include analgesic, antioxidant, antiinflammatory, anticancer, antirheumatic, spasmolytic, antihepatotoxic, carminative, atherosclerotic, choleretic, antidepressant effects and others. It also works against bacteria and viruses. Rosemary is widely used as a traditional medicine, so it is included in the EMA monograph. Extract of rosemary or substances isolated from it have been tested in many in vitro and in vivo studies. Essential oil...

Natural sources of lignans in our diet
NĚMEC, Petr
This bachelor thesis deals with lignans (phytoestrogens) in our diet. Preliminary of the work is focused on the characteristic of lignans, which belongs to the not entirely explored group of substances contained in various parts of the plant. The work reviews the most utilized crops (soy, flax, and cereals), from which was isolated a large amount of lignans and other compounds with estrogenic activity. Furthermore, there is introduced the list of substances contained in crops and mechanisms of their action in the human body. Their use is very beneficial in the prevention of serious diseases, so-called civilization. At the end of the work, there are highlighted various methods of separation of lignans from plants.
