Possibilities of preventing painful menstruation and the specifics of women in sports
Strolená, Alena ; Křivánková, Markéta (advisor) ; Nováková, Pavlína (referee)
Title: Possibilities of preventing painful menstruation and the specifics of women in sports. Objectives: The aim of this thesis is to compare methods focusing on exercise eliminatig or alleviating menstrual pain and also describe the specifics of women in sports in more detail. Methods: The main research method of the theoretical part of this diploma thesis is a search of Czech and foreign literature available from the university libraries of the Charles University, the Regional Science Library in Liberec, and then expert articles from the scientific databases Web of Science, Scopus and Pubmed. The practical part uses a method of comparison. Results: Premenstrual syndrome is followed by both emotional and physical changes. The occurrence and intensity of this syndrome is caused by neurohormonal and neurotransmitter changes, but also by the woman's lifestyle (symptoms worsened by stress, poor nutrition). There is also a close connection with painful menstruation (so-called dysmenorrhoea) and improper function of the pelvic floor muscles. Well-known methods focusing on pelvic floor exercises include the Moses Method, Kegel exercises, DNS method, and hormonal yoga. Three studies focused on Kegel exercises showed an improvement in the course of PMS and a decrease of incontinence, with the DNS method...

Pathophysiological aspects of critically ill patients and its influencing with hormonal and nutritional support.
Kafková, Anežka ; Hronek, Miloslav (advisor) ; Kovařík, Miroslav (referee)
The state of critically ill patients suffering from polytrauma or sepsis is characterised by pathophysiologic processes, which cause significant changes in an organism on both a local and a systematic level. A stressful situation elicits an acute inflammatory response. This response is primarily meant to be a defence mechanism; however, this mechanism might become harmful to a certain degree. Hormones, cytokines and growth factors are included among the main control mechanisms activated during inflammatory response. A metabolic response to a stressful situation is characterized by an increased turnover of proteins, lipids, and glucose. Clinical consequences may develop as a result of these metabolic responses and include inflammation, anorexia, immobility, increased vascular permeability (which results in edema), vasodilation, tachycardia, and increased cardiac output. There are some key factors which have a negative contribution on an inflammatory response. Those factors may include malnutrition, pre-existing inflammatory activity, severe infection, obesity, ageing, genotype, and finally gender-gene effects, which may also play a role. The development of significant hormonal changes can be typified for critically ill patients. Such changes are particularly connected to catecholamines, thyroid...

Mechanisms of gonad determination and differentiation in reptiles
Ehl, Jan ; Kratochvíl, Lukáš (advisor) ; Krylov, Vladimír (referee)
Reptiles, as a group, have a~lot of various types of sex-determining mechanisms. Evolution of sex- deter- mining mechanisms took place in different groups of reptiles by different way and got to different types of sex determination. Gene network underlying gonadal diferenciation has been investigated in many studies, for revealing of principles causing this diversity. Thanks to that, it is very difficult to determine ultimate trigger of switching between male of female fate.Interesting fenomenon is sexreversal, which is enabled by mechanism activated only by unusual circumstances. I have summerized basic facts about sex determination in reptiles in this work. Also, expresion patterns of some genes important for gonadal diferenciation in vertebrates, are recapitulated there. The last things, what this work posses, is summary of knowledge about sex-reversal in reptiles and short treatise about its evotution.
