Regional differences in somatic development of pre-school children in context of secular changes
Ferris, Stáňa ; Sedlak, Petr (advisor) ; Zamrazilová, Hana (referee)
Testing of regional differences in the growth and development of preschool children is a neglected topic in the history of anthropometry. In this work, we focused on the differences between the current population of Prague, Olomouc and Bratislava. Given the very similar living conditions and socioeconomic maturity of all three regions, we did not anticipate their presence. However, the results of this work showed significant differences, especially in skeletal robustness. Furthermore, we tested the presence of secular differences in the growth and development of preschool children between the current population of Prague, Olomouc and Bratislava and the reference data from 1990 for Czechia and 1989 for Slovakia. We expected changes in height, length and width body parameters, gracility of skeletal robustness, and, on the contrary, an increase in adiposity markers. In the case of the Prague population, this hypothesis was confirmed except for changes in the width parameters of the pelvis, where a negative secular trend was demonstrated. The results of the Olomouc and Bratislava populations do not agree with European trends and the established hypothesis. Secular trends in growth and development are mostly positive. Key words Regional differences, secular trend, preschool age, growth and developement

Microtubule-associated proteins in plants
Benáková, Martina ; Krtková, Jana (advisor) ; Vinopal, Stanislav (referee)
1. Abstract and key words MTs are one of the basic cellular protein structure. Their features and function are influenced and modified by group of other proteins, i.e. microtubule-associated proteins (MAPs). In the last decades, an extensive research on MAPs and their wide range of functions has been carried out. Therefore we are aware of the involvement of some of the MAPs in MT dynamics, other have been shown to have rather structural function. They bundle MTs with various cell structures, such as the other MTs, proteins, organelles, actin cytoskeleton or plasma membrane. Many described MAPs are homologous in the whole eukaryotic domain, for example MAP65 or EB1 (END BINDING 1) family, therefore it is interesting to follow if and how the functions of plant MAPs differ from their animal counterparts. On the other hand, there are many specific MAPs with unique functions in plants, e.g. ATK5 or SPR1 (SPIRAL 1). This Bachelor thesis is a survey on current knowledge of plant MAPs and it makes an effort to present their characteristic and functions in plant cell and organism. Key words: cytoskeleton, microtubules, microtubule-associated proteins, plant cell, growth and development

Nutrition of School Children
Máchová, Zuzana ; Váchová, Alena (advisor) ; Hanušová, Jaroslava (referee)
The healthy and right food plays a very important role in everybody's life. It works as a prevention of many diseases of civilization. Good nutrition can contribute to improve life quality. It gives a longer life and we stay more healthy. The most important thing in forming healthy eating habits is our own family. The next important factor is a school where children spend a lot of time. They create their own views and habits there. There are usually canteens at schools which offer some food to pupils. This dissertation is focussed on basic nutrients, education for a healthy lifestyle and the eating habits of pupils from 6 to 16 years at basic schools. I will also look into which food is preferred by pupils - healthy or unhealthy -their eating habits and the ways of their feeding. The aim of my dissertation is to find and evaluate eating habits of children of younger and older school age and detect if these children are interested in what they eat and if we can influence them by edification. In the practical part of my work I'd like to find out through a questionnaire what children at basic school know about healthy nutrition and a healthy lifestyle. The research was done at a peripheral basic school. The questionnaires were given to all pupils of primary and secondary school. The primary school's...
