The role of mitochondrial genome in cardioprotection induced by the adaptation to chronic hypoxia
Nedvědová, Iveta ; Žurmanová, Jitka (advisor) ; Polák, Jan (referee) ; Čížková, Dana (referee)
Cardiovascular intervention studies are a very important issue given that the ischaemic heart disease is one of the main mortality and morbidity causes in the Western world. Cardioprotection is mediated through a variety of signalling pathways in the cell that may directly or indirectly affect energy metabolism and mitochondria. Ischaemia-reperfusion injury of the heart significantly affect mitochondrial function revealing a potential therapeutic target. The role of mitochondria in the myocardium is not only in the field of energy homeostasis, but also in mediating the cellular response to reduced oxygen supply and in apoptosis regulation. This thesis aims to elucidate the response of the hypertrophied heart of the spontaneously hypertensive rat (SHR) and the derived conplastic strain with mitochondrial genome of normotensive Brown Norway (SHR-mtBN ) to the cardioprotective regime of adaptation to chronic normobaric hypoxia (CNH, Fi 0.1). The adaptive changes were studied at the cellular, protein and gene levels using Real-time RT-PCR, Biomark Chip Analysis, Western Blot, spectrophotometric measurements of enzyme activity and quantitative immunofluorescence analyses. The present thesis was based on a different cardioprotective phenotype between SHR and SHR-mtBN strains, i.e. a significantly smaller...
Invalid termination of the employment relationship by the employer
Čížková, Dana ; Drápal, Ljubomír (advisor) ; Morávek, Jakub (referee)
English Abstract Invalid termination of the employment relationship by the employer The topic of this thesis is the invalid termination of an employment relationship by the employer. The aim of the thesis is to conduct a comprehensive analysis of this point in labor law within the context of Act No. 89/2012 Coll., the Civil Code, which plays a major role in this issue as it pertains to subsidiary use in labor law. The Civil Code has brought a new understanding of legal defects of juridical acts that makes the juridical act either invalid or putative. It is just the putative juridical act that is a new institute implemented by the Civil Code. The relationship of the Labor Code to the Civil Code, including a historical excursion, is explained in the first part of the thesis. Furthermore, the thesis deals not only with the definition of the concepts of invalid and putative juridical acts in the context of labor law, but also with the development of these institutes in labor law. The main part of the thesis is devoted to the description and analysis of the individual cases of invalid or putative termination of an employment relationship by the employer, both on a general level and in specific cases using extensive case law. The thesis also deals with the individual consequences of invalid termination of the...
Decaying fungi on selected sites in protected landscape area Karlštejn
Tesárková, Monika ; Pešková, Vítězslava (advisor) ; Čížková, Dana (referee)
The thesis aims to evaluate the state of health of tree species growing in Karlštejn National Nature Reserve, with the main focus on ligniperdous fungi found in this location. Data were gathered in two experimental sites near Hostím and Bubovice villages, situated in the protected landscape area of Bohemian Karst (Český Kras). Tree species were inventoried in both designated sites and list of individual species of wood decaying fungi was put together. Furthermore, the state of health of tree species was evaluated according to crown defoliation and abiotic damage. The thesis also briefly describes the history of Bohemian Karst Protected Landscape Area and other related themes climatic and soil conditions, including geological and geomorphological characteristics of this region that significantly influence the natural character of the territory, including occurrence of ligniperdous fungi. The examination and subsequent controls of the selected sites took place once a month in period lasting from April 2015 to November 2016, revealed that only common species of wood decay fungi are found in the area of Karlštejn National Nature Reserve, which is part of Bohemian Karst Protected Landscape Area. These fungi are commonly present in the territory of the Czech Republic, therefore no unusual or new species of wood rotting fungi were found. The Korovitka (Diatrype) is the most widespread decaying fungi in both experimental plots, but the only one found fungal patogen Sphaeropsis sapinea, which in recent years has spread further and causes death and drying of pine trees has an economic importance for this area. Due to the good health of trees were found no major differences in the defoliation of trees, up to the aforementioned black pine attacked by fungi Sphaeropsis sapinea. There was observed defoliation from 45 to 100 %. There was no significant damage abiotic species found in the areas under examination.
Health condition of trees in the arboretum Bukovina
Hochová, Lenka ; Čížková, Dana (advisor) ; Šrůtka, Petr (referee)
Diploma thesis Health condition of trees in the arboretum Bukovina explains the damage of trees, tree diseases, impacts of deseases in its theoretical part. It also includes a brief summary of biotic and abiotic factors that cause damage. The Manionova stress theory, which clearly indicates the gradual effect of stressors on the species, is described. The second chapter is focused on the ways how is the health condition of trees assessed. The typical rating scale is also mentioned. The methodics is focused on finding damage of trees or other anomalies with subsequent determination of the method of damage in the area of the arboretum. Location arboretum in the area Hruboskalsko rock town gives the possibility to find such damages that are typical for dense, mature stands. The first trees were planted in arboretum in 1860, so it is expected that on this old trees many diseases are evident. I focused on introduced tree species that are typical for this arboretum, it is also mentioned visible damage of native woods. The result of the work is to evaluate the status of selected species and the end of the thesis show the table with the detected results. At the end of the discussion the results are confronted and some recommendations are proposed.

Health condition of of trees in natural monument Buky on Bouřňák
Wiedenová, Barbora ; Čížková, Dana (advisor) ; Vachová, Jana (referee)
In the thesis I focused on observing the occurrence of wood-decaying fungi on tree species in natural monument Buky na Bouřňáku. Two areas of 100 x 100 m were mapped, each contained hundred trees of various kind, mostly beech (Fagus sylvatica). The introduction summarizes information about the location and describes occurring pathogenic fungi and their expanding, biotic and abiotic damage and state of beech crowns. Observation was conducted from April to November, starting with the precise inventory of trees and their marking. Each subsequent month, I observed changes on specific tree species, recorded them and photgraphed detected fungal specimens. Individual species of wood-decaying fungi are described in my thesis. In the field, apart from fungi, I also observed the consequence of biotic factors that were evident on trunks, branches or assimilation organs. For individual species of beech, I recorded the condition of trees based on defoliation of the crown. The most frequently occurring wood-decaying fungi in the whole natural monument was Stereum rugosum. This fungi continues to spread and causes decline of several beech trees. Nevertheless I think the beech forest should be left to its spontaneous development, because it is a small protected area, more correctly natural monument.
Sensitivity of Czech provenances of European common ash and narrow-leaved ash to invasive pathogen Hymenoscyphus fraxineus
Kraus, Marek ; Pešková, Vítězslava (advisor) ; Čížková, Dana (referee)
This thesis deals with a survey of provenance areas and assessment of attacking Fraxinus excelsior L. and Fraxinus angustifolia by the pathogen Hymenoscyphus fraxineus. The aim of the thesis is to map the incidence of infected trees in these areas and to evaluate the sensitivity of the sites to the pathogen Hymenoscyphus fraxineus. The theoretical part deals with processing of data collected during field work on selected provenance areas Koneprusy and Veltruby. Amongst the evaluated parameters there were: trunk diameter at measuring height, tree height, and especially canopy drying caused by Hymenoscyphus fraxineus. As the outcome of the survey photographs were taken and records were collected for individual trees in the provenance areas. Each of the trees has its own unique label that has accurately defined its location to prevent potential errors in data processing. The processed data was then evaluated in NCSS 8.0 software and cluster analysis was performed in order to compare the provenances. This analysis only compares the provenances, which are located in both provenance areas. The results show that no provenance without the pathogen Hymenoscyphus fraxineus attack appeared in the provenances Koneprusy and Veltruby. Subjects in 4 ŠLP Kostelec nad Černými Lesy - Svojšice and 24 LS Czech Krumlov Chvalšiny proved to be more resistant than others. Although the increase in the tree height and the trunk thickness is the largest on those areas the defoliation rate is high. It is probable that the population of these provenances will gradually die. Due to growing abbility of some individuals located in other provenances it is obvious that habitat conditions and individual resilience are key factors.
