Šmídová, Zuzana ; Pejšová, Hana (advisor) ; Pechar, Radko (referee)
Probiotics and prebiotics constitute an important part of our nutrition and possess many positive effects on human organism. Synbiotics represent combination of both of them. The aim of the theses in the theoretical aspect was to create a systematic review of available knowledge on the given topics and in the practical part to assess the level of awareness on these topics with regard to their presence and effects. In the practical part of the theses the questionnaire survey methodology was used. After evaluation of all answers it was found out that most people are familiar with the term probiotics, less people with the term prebiotics and the least respondents with the term synbiotics. Fermented dairy products are consumed by 88,3 % of respondents, mostly 2-3 times a week. The rest not consuming them indicated mostly the reasons of bad flavour or some form of intolerance. The respondents know also other fermented foods (sauerkraut, vegetables), however, these are less consumed than fermented dairy products. The least often the food supplements containing these substances are consumed. Due to the low level of awareness on prebiotics and synbiotics it would be very appropriate to improve public awareness on the given topics in order to increase their consumption, mainly in the form of their natural...

Ježková, Kristýna ; Pejšová, Hana (advisor) ; Křížová, Jarmila (referee)
This diploma thesis deals with fiber intake and possibilities of its increase. The main aim of the thesis is to evaluate the actual intake of fiber in the population and to find out whether people actually know what fiber is and what should be its daily intake. The theoretical part is focused on fiber itself. It describes its characteristics, distribution, properties and sources. The effect of fiber on human health and the consequences of insufficient or excessive fiber intake are discussed as well. The practical part is focused on the real intake of fiber in the population. It is done in the form of a questionnaire survey, in which I try to find out what knowledge of fiber people have, but also how often they consume foods containing fiber. Most of the questionnaires were handed out to customers of one unnamed pharmacy and healthy nutrition center in Prague and other passers-by. Altogether, I managed to collect 84 questionnaires. The questionnaire results show that vast majority of respondents have an idea of what fiber is and which foods contain it most; however, they do not know what the recommended daily intake is. Still, half of the respondents think their diet includes enough fiber. The fiber intake in men and women was not much different. The most significant difference was in the...

Alergenogenní epitopy u klíšťat
In this study we focused on detection of galactose-alpha-1,3-galactose (alpha-gal epitope) as to determine the proteins which carry this glycan in ticks. Affinity chromatography with magnetic beads was used to purify the proteins from tick cell lines. The proteins obtained were visualized by SDS-PAGE and western blotting. Purified proteins were then identified using mass spectometry. Fluorescence microscopy was also used to detect Gal as well as another allergenogenic epitope, the core alpha-1,3-fucose, in ticks cells.

According to the World Health Organisation (WHO), allergic diseases in the economically advanced countries of the WHO have become the largest child environmental epidemic. Dysregulation of immune tolerance is the basic mechanism involved in the development of food allergy. It is believed that the risk of developing allergies is more related to other lifestyle factors such as a diet, physical activity or obesity. Food allergies in children and adult populations vary both in the spectrum of triggering foods and also their symptoms and their severity. The prognosis also differs in allergies for different types of foods. One of the most important factors affecting the correct development of the baby's immune system is nutrition. In the first 4 - 6 months, the baby should only receive breast milk - for infants it is the most appropriate and allergenically safe diet. It strengthens their immune system. Its positive effect is observed especially on the occurrence of food allergies and atopic eczema. However, developing asthma and other allergies may not be prevented.
