Tomaňová, Vendula
The thesis deals with user research and the subsequent design and implementation of a product, which is a gaming desk. The thesis aims to get inspired by the current representation of furniture for this specific sector on the market, as well as the requirements of a particular user group. Finally, it translates the result of the work, which is a gaming computer desk.

Presence of specific DNA and coproantigen of Cryptosporidium as an indicator of ongoing infection
TOMANOVÁ, Vendula
Cryptosporidium is a genus of apicomplexan unicellular epicellular parasite with worldwide distribution causing watery diarrhea in humans and animals. The life cycle is completed in one host, where Cryptosporidium parasitizing epithelial cells of gastrointestinal tract and in birds can cause disease of respiratory or urogenital tract. Course of disease depends on condition of immune system. For immunodeficient individuals could be life threatening. One of problems especially in developing countries is early and correct diagnostic, particularly no effective treatment currently exist. The aim of this thesis was to compare efficiency of immunochromatographic tests in samples stored under different conditions. The comparison of sensitivity and specificity of these tests with molecular and microscopic techniques was also performed. Additionaly, suitability of immunochromatographic tests for detection of active infection during prepatent period was evaluated. The theoretic part includes general information about Cryptosporidium. Its taxonomy, cycle of evolution or transmission and course of disease. Using of immunochromatographic test is also mentioned. No differences in sensitivity of used immunochromatographic tests was observed in this thesis. The detection rate for most of tests was 200 oocyst per sample. The presence of coproantigen is depend upon presence of oocysts in a sample. False negative results of immunochromatographic assays was caused by i) low concentration of oocysts in a sample (sensitivity) or ii) antibodies in used test don´t react with antigen of Cryptosporidium spp. (specificity). Results of this thesis show that combination of immunochromatographic tests and other techniques is convenient. During prepatent period is not possible to detect specific DNA, antigen or oocysts of Cryptosporidium. The active infection could not be distinguish from passage of oocysts using of immunochromatographic assays even if PCR is also used.

Milk as potencial source Encephalitozoon cuniculi
TOMANOVÁ, Vendula
The object of this thesis is to find out an incidence and prevalence of Microsporidia infection in uncooked cow´s milk. Samples of milk, faeces and urine from 147 milk cows were screened. One of them was positive for presence of Encephalitozoon cuniculi in sample of milk and stool repeatedly. Theoretic part includes information about Microsporidia, e.g. developmental cycle, transfer and course of disease, treatment and prevention. There is a description of heat treatment of milk as well. A methodical procedure of microsporidia DNA detection from samples of milk, feaces or urine is described in the practical part. The thesis is focused on experimental verification of sterilizing capabilities of various pasteurization methods. Milk was contaminated by Encephalitozoon cuniculi and then heat treatment according to the methods used in practice followed. Contaminated milk was offered to laboratory immunodeficient SCID mice. After three weeks mice were put to death and their organs were examined for the presence of Microsporidia DNA using molecular methods. Finding out of Microsporidia in examined organs was the evidence of insuffient heat treatement.
