The introduction of diagnosis of new bacterial pathogens Inquilinus and Pandoraea isolated from patients with cystic fibrosis and determining their sensitivity to antibiotics
Šulcová, Romana ; Melter, Oto (advisor) ; Nyč, Otakar (referee)
Cystic fibrosis is one of the most common autosomal recessive hereditary disease. Nowadays, people, with this disease, because early diagnosis and treatment of other associated symptoms a better prognosis than a few years ago. CF is a disease that is subject to mutation of the CFTR (Cystic Fibrosis Transmembrane Conductance Regulator) on the seventh chromosome. Defect in the CFTR protein leads to failure of resorption and secretion of electrolytes chloride channel and thereby creating viscous mucus in the lungs, which is the main cause of chronic bacterial infections of the lower airways. Among the most common pathogens causing severe respiratory infections in CF patients include: Staphylococcus aureus, Pseudomonas aeruginosa, Burkholderia cepacia complex. In patients with CF is now showing in the airways of new bacterial species whose biological properties are not yet known and their role in the etiopathogenesis of the disease and epidemiology are not exactly known. In these days their detection is used by specific amplification methods, or sequencing of the 16S rRNA gene. Emerging pathogens such as the genus Pandoraea and Inguilinus that belong non-fermenting Gram-negative groups in the rods, and therefore are often exchange for other bacterial species that are phenotypically similar to them.

Analysis of the balance of payment of the Czech Republic in a long term horizon - chosen problems
Martincová, Tereza ; Plchová, Božena (advisor) ; Nigrinová, Lenka (referee)
This bachelor work focuses on a theoretical approach to the balance of payments in the first part, particularly on a definition of the balance of payments, structure of the balance of payment and last but not least it deals with a choice of a suitable balance of balance of payments for assessing the external economic stability. Second, practical part is devoted to a development of individual items of the balance of payments between 2000-2007 and evaluates the balance of payments as a whole. The third part reports on the influence of direct investments on the balance of payments and rates teritorial, structural and branch orientation of foreign direct investment in the Czech Republic and czech investment abroad. In this part, there is also very briefly mentioned the influence of the exchange rate of the Czech Crown onto the balance of payments and evolution of the Czech Crown since its begining.

The method of DNA barcoding and its use in protists
Rotterová, Johana ; Čepička, Ivan (advisor) ; Fiala, Ivan (referee)
DNA barcoding is a molecular method of species identification based on short regions of DNA sequences. These DNA barcodes should be unique for each species. The sequences within species should be identical or very much alike, while between species they should display a significant amount of differences. The sequences of an undetermined specimen can be compared with sequences vouchered to a particular species in a global DNA barcode database. The database was developed with the aim to simplify traditional taxonomy, eliminate its problems and accelerate its approaches. However, DNA barcoding has its own limitations that may hinder achieving its original goals and a compliance with the concept. The aim of this bachelor thesis consists of explaning the evolution of DNA barcoding through time and assessing the importance of this method at present, particularly in protists. Species identification may be very difficult in many protist groups, which can be explained by several reasons. To appraise this method completely is a hard task, because creation of the database has not yet been finished and official DNA barcodes have not been chosed for many groups. We can only find out in the future, therefore i will only focus on factors that influence the success of DNA barcoding at present.

Comparative cytogenetics of bed bug Cimex lectularius (Heteroptera: Cimicidae)
Sadílek, David ; Vilímová, Jitka (advisor) ; Ráb, Petr (referee)
Comparative cytogenetics of the bed bug Cimex lectularius (Heteroptera: Cimicidae) The human bed bug Cimex lectularius has started enormous spreading to all developed countries of temperate climate zone during the last ten years. Bed bug was almost eradicated by a mass use of DDT in these areas until the 70's in the 20th century. This temporal haematophagous ectoparasite occupies particularly human dwellings and bat roosts. Cimex lectularius shows unusual combination of cytogenetic characteristics, general for all Heteroptera, however, not usual for other organisms. The chromosomes are holokinetic, with completely achiasmatic meiosis and inverted meiosis of the sex chromosomes. Especialy remarkable feature is intraspecific variation of the number of the X chromosomes. The variable number of chromosomes of 43 populations of Cimex lectularius from the Czech Republic and 27 populations from other European countries was studied in the present study. The 10 variants of karyotype were found out by using the "hotplate spreading" method and the standard Giemsa staining. There were male karyotypes with 2n = 29, 30, 31, 32, 33, 34, 35, 37, 42 and 47 chromosomes and two females with peculiar odd number of sex chromosomes X, 2n = 33 and 43, not complementary with any male. A stable number of 2n = 26 autosomes...

Locomotor expression of poems with pre-school children
Hujerová, Václava ; Hník, Ondřej (advisor) ; Klumparová, Štěpánka (referee)
The object of my disertation is connection poetry and locomotion with pre-school children. The goal of my research is realize, which poems and motions are prefered by children and what is the reason of their choose. The methods in my dissertation are interview, experiment and observation. All of these methods detect relation of children to poetry and locomotion. I have discovered the interesting style of work with pre-school children. The children have appreciated various language and form resources. I have discovered, that children love particularly dynamical and simple activities, which enable maximum discharge of energy. I will trying to choose the poetry and locomotion, which is the nearest for pre- school age.I hope, that my discovered will be interesting inspiration for teacher in kindergarten.

How Does Monetary Policy Change? Evidence on Inflation Targeting Countries
Baxa, Jaromír ; Horváth, R. ; Vašíček, B.
We examine the evolution of monetary policy rules in a group of inflation targeting countries (Australia, Canada, New Zealand, Sweden and the United Kingdom), applying a moment-based estimator in a time-varying parameter model with endogenous regressors. Using this novel flexible framework, our main findings are threefold. First, monetary policy rules change gradually, pointing to the importance of applying a time-varying estimation framework. Second, the interest rate smoothing parameter is much lower than typically reported by previous time-invariant estimates of policy rules. External factors matter for all countries, although the importance of the exchange rate diminishes after the adoption of inflation targeting. Third, the response of interest rates to inflation is particularly strong during periods when central bankers want to break a record of high inflation, such as in the UK or Australia at the beginning of the 1980s.

Episodic like memory in nonhuman animals
Gálik, Michal ; Landová, Eva (advisor) ; Vlček, Kamil (referee)
Episodic memory refers to an ability that allows a person to mentally re-enact past events from his own life. This capacity was long considered to be uniquely human. The best evidence of this ability in humans is subjective consciousness, which accompanies episodic recollection. For this reason, it is particularly difficult to study such cognitive ability in other animal species. However, there is some indirect evidence showing that animals could possess the ability of episodic memory to some degree. This bachelor thesis summarizes recent knowledge about episodic memory, provides an overview of specific studies in different animal taxons and compares the methodologies used by various authors to demonstrate episodic memory in animals. It focuses mainly on birds, rodents and primates. KEYWORDS : Episodic memory, Episodic-like memory, Hippocampus, Cognitive ability, Animal model

Collection of aquatic and wetland plants, Institute of Botany, Academy of Sciences of the Czech Republic, Třeboň
Navrátilová, Jana ; Husák, Štěpán ; Adamec, Lubomír ; Dvořáková, Kateřina
The Collection of Aquatic and Wetland Plants of the Institute of Botany AS CR in Třeboň was founded in 1976 with the aim to enable ex situ studies of threatened plant species. Since that time the Collection has provided plant material for experiments, repatriation of threatened species, taxonomical studies, and botanical illustrations for the compendium Flora of the Czech Republic. It is also used as an educational collection for university students and public. Since 1998, the seeds from the Collection (about 150–200 species each year) have been collected and offered for exchange to other institutions and botanical gardens within the Index Seminum. The Collection of Aquatic and Wetland Plants is located in the Section of Ecology of the Institute of Botany in Třeboň on an area of about 0.04 ha and its current design come from 1997. The Collection includes more than 400 species grown in outdoor containers and in a greenhouse. The overwhelming majority of these species are native to the Czech Republic; the others are mainly from other parts of the northern temperate zone. The Collection of Aquatic and Wetland Plants is the largest collection of living higher aquatic and wetland plants in Europe and one of the largest collections in the world.

Comparison of ecological requierements of the epiphytic species within Orthotrichaceae family
Franková, Hana ; Plášek, Vítězslav (advisor) ; Hejda, Martin (referee) ; Marková, Ivana (referee)
The thesis is a part of an ongoing research on taxonomy, ecology, and the distribution of epiphytic bryophytes particularly within the Orthotrichaceae family, based on collected bryofloristic records. The database now contains 6500 records. I have analysed interspecific differences in habitat preferences between species, namely their associations with particular phorophytes, pH of phorophyte bark, altitude, and the position on the phorophyte. Individual species differed in their occurrence according to altitude, phorophyte, and pH, though altitude was the most important factor. All analysed species have been shown to represent obligate epiphytes. Some species reveal a tendency to occur preferrentially on northern or western side of the phorophyte, but this tendency is not by any means universal. I discuss these findings in the context of the knowledge of species autecology and current changes in their distribution.
