Nutrition in osteoporosis
SOTONOVÁ, Michaela
The Bachelor's thesis focuses on nutrition for osteoporosis. The main aim of the thesis is to determine and evaluate diet composition in the selected retirement home and to find out whether the composition of the diet corresponds to the requirements for osteoporosis prevention or nutrition therapy. Another aim is to create recommendations for menus in the retirement home which comply with the physiological needs of seniors. I would also like to find out whether the respondents know the relationship between individual nutrients and osteoporosis. The thesis is divided into a theoretical and a practical part. The theoretical part describes the physiology and anatomy of bones. Furthermore, it also concentrates on the characteristics of osteoporosis, its forms, symptoms, risk factors and diagnostics. The last section of the theoretical part focuses mainly on nutrition, which is related to osteoporosis. In the Bachelor's thesis, I emphasize the importance of calcium, vitamin D, magnesium and other key macro and micronutrients associated with this disease. The research part of the Bachelor's thesis was carried out using a quantitative and qualitative research method. The quantitative part of the research was conducted by means of a questionnaire survey in the retirement home in Strakonice. The paper questionnaire was distributed to 30 respondents (15 women and 15 men). It was divided into two parts. The first part focuses on awareness of this disease. The second part deals with the respondents' knowledge of the role of nutrients in osteoporosis. Next, the qualitative research method was used to obtain weekly menu that is used to prepare meals for people with osteoporosis. I entered the weekly menu into the Nutriservis Professional program and then evaluated it. I specifically paid attention to the sufficient calcium and vitamin D intake. I processed the results of the research into graphs using Microsoft Excel 2016.

Structural and Chemical Aspects of Calcium Phosphate Formation in Tooth Enamel
Kallistová, Anna ; Skála, Roman (advisor) ; Frýda, Jiří (referee) ; Oldak, Janet (referee)
Tooth enamel is the hardest and most resistant highly mineralized inorganic component in mammalian bodies that significantly affects both the life quality and expectancy of an indi- vidual. Its specific qualitative properties are given by the biomineralization process responsible for its formation. In this process the mineralization of hydroxyapatite (HAp), the only inor- ganic phase composing the mammalian hard tissues, is controlled by activity of enamel-forming cells ameloblasts and their products. Over the past years, the studies of enamel matrix pro- teins, their structure, composition and function has become the prevalent field of experimental investigation. However, unique enamel qualities, which enable the teeth to withstand high pressure and stress demands, cannot be accurately assessed without the thorough systematical study of its mineral compound. In this thesis, I focus on the crystallographic and compositional characteristics of enamel hydroxyapatite and their influence on the mechanical properties of teeth. Obtained results are discussed in context of developmental and adaptation dynamics of mammalian species. The main aspect of the work is to extend our knowledge about the protein-mediated mineraliza- tion process from the perspective of inorganic compound and its contribution to the...

Neinvazivní metody v léčbě pohybového aparátu koně
Pražáková, Jana
Title of the bachelor thesis is "Noninvasive methods in the treatment of musculoskeletal system of the horse". It contains the basic information from the field of anatomy and biomechanics of the horse. It describes various treatment methods used in practice. It deals with their possible influence on the horse. Also solves the problems of smuggling and saddle choice, which is often neglected. Shows the effects of the methods and their effects on horses. It includes not only the physical affecting horses, but also influences acting on the psyche of the horses. The whole thesis is focused on selected treatment methods. These methods are considered to be a very important tool of prevention, rehabilitation and also a good way to keep a horse in the best possible condition, health and psychological balance. Prevention is better than a subsequent complicated and expensive treatment. It is therefore necessary for cooperation between vet, a physical therapist and owner of the horse. And then suitably designed combination therapies.

Kompozitní pěnové nosiče pro tkáňové inženýrství kostí
Kuntová, Henrieta ; Rampichová, Michala (advisor) ; Krulová, Magdaléna (referee)
The goal of my work was to introduce the fast pacing field of tissue engineering with focus on bone regeneration. Tissue engineering could be a future alternative to the currently used conventional approaches that suffer from healing failures. Due to increasing demand for bone tissue replacement damaged by degenerative diseases or injuries, many laboratories have attempted to come up with solutions in a form of artificial constructs. In the present light of interest are composite scaffolds usually made of polymer and ceramic combinations. Their main advantage is that they combine elasticity and tensile strength of a polymer with bioactivity and mechanical hardness of a ceramic, while removing drawbacks of each material.

Osteoporosis - prevention and treatment of nutrition
KUBECOVÁ, Monika
The theme of the bachelor thesis is devoted to the issue of a disease called osteoporosis. In the theoretical part, I briefly describe the anatomy and physiology of bone, then I define what osteoporosis is, what are the risk factors, what is its incidence in the population and primarily I deal with the connection of nutrition and the prevention and treatment of the disease. The prevention emphasizes the importance of calcium, its food sources and other important elements associated with osteoporosis, such as vitamin D. The chapter concerning supplementation is crucial in the treatment of osteoporosis. In the practical part of my bachelor thesis, there was aimed to answer the questions on women's knowledge in the prevention of osteoporosis, and the behaviour of women in the prevention of nutritional perspective. The quantitative part of the survey was conducted by the questionnaires. I distributed the questionnaire in printed form to 74 women aged from 50 to 90 years. Then, I divided these women into two age categories, from 50 to 70 years and from 71 to 90 years. I have compiled the outcome of each question into a chart with the help of Microsoft Excel 2007. For the qualitative part of the research, two women wrote down their weekly eating habits into the record sheets. These practices were analysed with the help of a nutrition program Nutriservis, especially, I was interested in calcium content. According to the research results, most women have lack of calcium intake. The research also implies that they do not know the correct daily amounts of milk and dairy products, because they said that a reasonable portion is one or two dairy products a day.

Trace elements and Pb isotopes in selected bone samples
Bartoš, Jan ; Mihaljevič, Martin (advisor) ; Strnad, Ladislav (referee)
The aim of this work is briefly summarize the current theoretical knowledge about trace elements and their inputs into calcified body tissues in a form of search. Here are described mechanisms of their inputs and depositing into human body and principles, which allows maintenance of their optimal levels. In this paper are also described the properties of bones and teeth and simply explained concepts such as an essential and toxic trace elements. The next part of this work is mainly about trace elements, which have the biggest potential to be used in an archeological research, particularly in paleodietary research. These elements are mainly Sr, Ba and Zn. Lead and its isotopes are discussed more here in relation to the effect of Pb to Romans in the past and to the identifying sources of pollution by this element. In the same chapter are also described principles of post-mortem alteration processes, to which are bones after burial exposed and which they have to face during analyzing and interpretations of data related to the amount of trace elements in origin bones.

Ancient-DNA analysis of teeth and skeletal remains with utilization of miniSTR loci.
Kvítková, Dana ; Brouček, Jaroslav (advisor) ; Dobisíková, Miluše (referee)
During the last twenty years, immense progress occurred in the area of analysis of DNA extracted from historical material. Considering the common level of preservation of tissue material, this analysis is usually executed on samples procured from bones and teeth. The analysis of soft mummified tissue is possible only in rare cases. Limiting factor of these analyses is a high degree of degradation and small amount of DNA extractable from this kind of material. First researches concentrated only on short sections of mainly mitochondrial DNA. Today, the analysis of the complete mitochondrial genome of both contemporary and extinct organisms was made possible. In case of analyses conducted on human remains, sections of nuclear DNA are far more valuable, because they can reveal information including not only subject's sex, but also possible kinship between subjects found e.g. in the same grave. Fundamental component of the whole analysis is the process of extracting DNA from cells. Probably every laboratory working with historical DNA uses a differently modified extract protocol. The main requirement for methods of extraction is to secure enough DNA with such a level of purity that would allow its use for following steps of the analysis. Taking in consideration high fragmentation of DNA, it is necessary...
