Testing of biological effect of glucans on cell lines in vitro
Šimková, Eva ; Holub, Jiří (referee) ; Němcová, Andrea (advisor)
The aim of this bachelor thesis is isolation and testing of -glucans from selected strains of yeast. In the theoretical part, characterisation of -glucans, microbial production of -glucans by yeast, determination of polysaccharides, exopolysaccharides and in vitro testing are described. Yeast have a cell wall made up of -glucans and -glucans are known for their healing properties. In the experimental part of this work deals with characterization of selected biomass yeasts in different forms and comparison of their effects and the amount of -glucans in each form. Stains of Metschnikowia pulcherrima, Cystofilobasidium infirmominiatum and Rhodotorula kratochvilovae have been selected for this thesis. Subsequently, the thesis deals with the isolation and testing of isolated -glucans from a selected lyophilised strain of yeast Rhodotorula kratochvilovae. The selected strain was isolated in 2 ways. The first method of isolation that was more friendly to conformation of -glucans due to the effect of ultrasonic homogenization of cells. The second method of isolation was less friendly to -glucans, using acid and base to homogenise them. Analyses of both extraction methods confirmed the presence of isolated -glucans, however it was found that the recovery of both methods was relatively low and requires further optimisation of the procedure. Overall, the better extraction procedure was the second method. A sample of this extract was further tested on the HaCaT cell line. The results of the pilot tests confirmed the cytotoxicity of the extract obtained by us.

Metafictional narrative strategies of two Cervantes' Exemplary Novels
Krátká, Tereza ; Holub, Jiří (advisor) ; Sánchez Fernández, Juan Antonio (referee)
The aim of the work is to sum up main function of the metafictional narrative strategies in two Cervantes' Exemplary Novels - The dialogue between Scipio and Berganze and The deceitful marriage. At the beginning, the text is focused on composition of both novels, mainly on their narrative structure. In the next part, the work is concentrated on analysis of reminiscences relevant - as for novels' genre, language and style - for interpretation of metaficitonal narrative with respect to the period of baroque upcoming. Then, the narrative structure is compared with Cervantes' novel Don Quijote which is based on the same type of narrative strategy. The author comes to the conclusion that the primary function of the metafictional narrative strategies is a possibility to interpret the question of the truth in relation to the baroque reality of the 17th century in Spain. The main importance of the work is presentation of a detailed narrative scheme of two novels, up to now absent in majority of theoretical works aimed at Exemplary Novels composition. Key words: Miguel de Cervantes, Dialogue between Scipio and Berganze, El coloquio de los perros, metafiction, intertextuality, credibility, narrative strategies.

Use of technical hemp extracts in hair cosmetics
Benková, Sarah ; Holub, Jiří (referee) ; Márová, Ivana (advisor)
Technical hemp as a versatile plant has found applications in many sectors of the industry. In cosmetics, it is mainly used for bioactive substances as well as proteins. The subject of this bachelor thesis was the preparation and characterization of a fraction containing hydrolysed hemp proteins and its use in hair cosmetics. In the theoretical part, the characteristics of the plant as well as its chemical composition are processed. Attention is paid especially to hemp proteins, their hydrolysis possibilities, and the subsequent use of hydrolysates in hair cosmetics. Within the experimental part, the preparation of hemp protein hydrolysates from hempseed cake of the Santhica 70 variety was optimized using the industrial enzymes TS-E 1930 and TS-E 1993 and the subsequent determination of the protein content and profile of prepared hydrolysates. The carbohydrate, chlorophyll, phenolic and flavonoid content of the analysed hydrolysates was also determined. A hair conditioner was prepared from the selected hydrolysate and tested by ten respondents. Thanks to the prepared conditioner, hair cosmetics with the addition of hydrolysed hemp proteins has been shown to enhance shine and pliability of the hair, as well as help the healing of frayed ends.
