Měď redukující účinky metabolitů kvercetinu / Copper reducing effects of quercetin metabolites

Mísař, Jakub January 2016 (has links)
Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical Botany and Ecology Candidate: Jakub Mísař Supervisor: PharmDr. Jana Karlíčková, Ph.D. Title of Thesis: Copper reducing effects of quercetin metabolites Copper is an essential trace element in particular due to its ability to easily convert between both redox forms: oxidized (Cu2+ ) and reduced (Cu+ ). Flavonoids are common components of the human diet and they can have positive influence on human health. They are converted into small phenolic acids during digestion by specific bacteria in the colon. Although effects of flavonoids have been extensively studied, the same is not true for their metabolites- phenolic acids. In this in vitro study, eight phenolic acids, which are known metabolites of commonly used flavonoid quercetin, were analyzed for their copper reducing activity at four (patho)physiologically relevant pHs. Simple spectrophotometric method based on an indicator bathocuproinedisulfonic acid disodium salt was used for the assessment reduction of copper ions. The degree of cupric reduction differed among tested compounds. All o- dihydroxycompounds were the most active and achieved 100% of cupric ion reduction in low compound to copper ratio. In conclusion, based on this study, it appears that...

Morávková, Markéta January 2015 (has links)
Title: Physical activity in facilities for the elderly as a means of self-care and independence Objective: The main objective is to identify through research the possibilities of movement activities of seniors in institutions for the elderly, as a means to their autonomy, self-care and independence of the surrounding area. Senior age brings with it many challenges and constraints, whether physiological or psychological means. According to my research (Morávková 2013), these problems can actually affect by physical activity in both primary and secondary prevention. But the question remains whether seniors have the opportunity to perform physical activity. In my research, I focused on a situation where the senior placed in a facility for the elderly and is therefore totally dependent on the supply of equipment. Methods: The thesis is the first part researches topics of geriatrics and physical prevention of seniors. In the second part I follow research which I addressed to all traced facility for seniors in the Central Region, a total of 49 homes. There I poll examined whether there are controlled hours of physical activity, how they are targeted, whether this benefit seniors exploits and possibly what finances have to spend to participate those hours. Then I processed incoming data and interpreted...

Vliv stromů na kontaminaci půdy 137Cs / The influence of trees on contamination of soil with 137Cs

TRNKOVÁ, Michaela January 2019 (has links)
Nuclear weapons testing in the atmosphere and accidents in nuclear energy facilities in the last 50 years caused significant contamination of the environment. Half-life of certain leaked radionuclides is several decades and therefore they are still present in today's environment. That is the reason why there is still on going monitoring of radiation situation in the Czech Republic in order to determine the behaviour and kinetics of anthropogenic radionuclides in the environment and the severity of radiological impact on humans. The results of this monitoring serve to review the radiation situation, observe long-term trends and last but not least to gain new knowledge that could facilitate the management od radiological emergencies. The aim of this thesis was to measure the content of 137Cs in soils under and around leafy tree crowns in the area affected by radiation fall and to find out whether the tree's crown has an effect on the distribution of 137Cs in the soils below them. To this end, a research question has been set: Do tree crowns affect the distribution of cesium in the soils below them? For better intelligibility, the introduction of the thesis is devoted to information about ionizing radiation, basic terms and quantities in the field of ionizing radiation, sources of radionuclide contamination, especially the Chernobyl nuclear power plant accident, environmental and population contamination, and elements important for the practical part of this work. The theoretical part is followed by research methodology. The soil samples were collected under five leafy trees of the Walnut species that met the set criteria for collection. Under each tree, samples were taken in three directions at an angle of 120° always at the trunk, in the middle of the crown, at the edge of the crown and outside the crown. Thus, 12 samples per tree, a total of 60 samples. Dry and purified soil samples were measured by semiconductor gamma spectrometry which determined 137Cs radionuclide mass activity values as well as naturally occurring radionuclide40K. Graphs were generated from the measured values. Despite the frequent deviations that may be caused by natural phenomena or human activities, it was found out that tree crowns affect the distribution of 137Cs in the soils below them.

Psychofyziologické koreláty emocí a paměti / Psychophysiological correlates of emotion and memory

Jindrová, Miroslava January 2019 (has links)
The first aim was to determine the baseline psychophysiological correlates in healthy subjects as a first necessary step towards the long-term goal of application the psychophysiological techniques in diagnostics mood and cognitive disorders. The second aim was to establish an easily applicable set of tests for evaluating emotional and memory processes by non-invasive psychophysiological methods. EEG, GSR, and eye-tracking data from 100 participants without any neurological or psychiatric disorders were obtained during watching affective pictures and performing memory tests. The spectral powers were computed for each 500 ms of the stimuli in theta, alpha, beta1, beta2 and beta3 bands in 12 areas of the brain. Lower alpha and higher beta3 power was related to higher emotional intensity. Negative emotions were distinguished in spatio-temporal changes of beta1 power and positive emotions showed higher beta3 power in right temporal region. Memory encoding showed higher alpha power. Lower theta and higher alpha power in central regions and overall increase of beta bands were observed during successful memory retrieval. A summary of spatio-temporal spectral correlates to emotional and memory processes was provided by this work. Key words: Electroencephalography, electrodermal activity, psychophysiology,...

Aktivní životní styl a tělesná kondice adolescentů na zvolené střední škole v okresním městě Jihočeského kraje. / Active lifestyle and physical fitness of adolescents at selected high school in the district of the South Bohemian Region.

ROUČKOVÁ, Veronika January 2019 (has links)
The diploma thesis deals with the active lifestyle and physical condition of adolescents at the chosen school in the district town of South Bohemia. The research was chosen by the Higher Secondary School of Social Studies and the Secondary School of Education in Prachatice and specifically by 53 students of the third year of secondary pedagogical school. The aim of the work was to monitor the body composition, aerobic capacity, muscle strength and mobility of the students on the basis of the batteries tested by the internet portal Indares. To compute the results, the Statistics program and it's forms of parametric and nonparametric tests were used. It follows from the calculations that, in terms of statistical significance, the students did not show very positive results, however, from the point of view of the subject matter it can be stated that according to the standards their performance was average, in some individuals it was above average. Research questions and hypotheses are partly confirmed at the end, but also partly disproved from what it can be concluded that more respondents would be needed for this research for more authoritative results.
