Impact of temperature and drought on gliadins and glutenins contents in four varieties of wheat
Tomasz, Teresa ; Vítová, Eva (referee) ; Hrstka, Miroslav (advisor)
This diploma thesis deals with an influence of high temperature and water shortage on the protein content of gliadin and glutenin fractions in four varieties of winter wheat: Bohemia, Tobak, Pannonia and var. Syria with designation S46 (IG142780). The crop was grown at 26, 29, 32, 35, 38 and 41 °C during anthesis under control irrigation treatment (with soil moisture higher than 70 %) or under drought stress (with soil moisture lower than 30 %). To separate gliadins, the A-PAGE method was used, and glutenins were separated by SDS-PAGE method. Proteins were quantified by computer densitometry. Significant influence of genotype on the gluten proteins was found. Variety Pannonia has high content of -, 5-gliadins, LMW and HMW glutenins, but low content of other gliadin fractions. It was the opposite in the other varieties. Due to temperature, as well as drought, there was an increase in the content of all gluten fractions, especially of HMW glutenins, 1,2-gliadins and total gliadins. The largest increase in the gluten fractions due to drought was observed in Syria variety. In other varieties simultaneous exposure to drought and heat caused decrease in gliadin content, but increase in glutenin content. Drought at high temperatures reduced gliadin-to-glutenin ratio, mostly in Bohemia variety. This ratio has increased due to the temperature, especially in Tobak variety. For Syria variety, no effect of stress conditions was found on gliadin-to-glutenin ratio.

Detection and genotypisation of Helicobacter pylori strains in Waldeyers lymphatic tissue and its relationship to the formation of pathologies in this area
Nártová, Eva ; Astl, Jaromír (advisor) ; Smilek, Pavel (referee) ; Slípka, Jaroslav (referee)
The aim ofthis study was to reveal the presence ofHelicobacter pylori (HP) in the Waldeyers lymphatic tissue in the group ofchildren and adults, along with its possible role in the etiology of tonsillar carcinoma and benign diseases (chronic tonsillitis, OSAS, adenoids). In our study we have confirmed the hypothesis that HP is presented m the Waldeyers lymphatic tissue. as well as in the stomach and that the oropharynx and epipharynx are the an extragastric reservoir ofHP. Mucosa associated lymphatic tissue in the stomach is similar to lymphatic tissue ofWaldeyer ring. These conditions can be very favourable for the survival ofHP and thus can promote inflammation changes and immune changes as well as in the stomach. ln our study, using the real-time PCR method we have detected high incidence ofHP DNA in adenoids and tonsillar tissue. ln the group ofbenign diseases, the most frequent genotypes were CagA VacAsIbm1 and CagA-VacAslbm2. In the group of patients with tonsillar carcinoma, the most frequent genotype was CagA-VacAslbml. Genotyping identified strains ofHP showed differences in comparison with the predominant strains which are most frequently found in the stomach. Genotypic analysis ofI-IP strains showed that the less prevalent virulent strains ofHP, known as cagA negative and vacA positive....

Genotype and fenotype characterization in patients with ALS and ALS-FTD in Czech and Slovak Republic
Navrátilová, Nela ; Šlachtová, Lenka (advisor) ; Šípek, Antonín (referee)
Amyotrophic lateral sclerosis (ALS) is a rare and fatal neurodegenerative disease characterized by the degeneration of upper and lower motor neurons in the brain and spinal cord. It manifests itself with gradual muscle weakness and atrophy, and patients commonly succumb to respiratory failure within 2-4 years of disease onset. Frontotemporal dementia (FTD) is one of the three most prevalent early-onset dementias, characterized by the degeneration of frontal and temporal brain lobes leading to progressive deterioration of cognitive functions, behavior, and language abilities. These two clinical entities intersect within the ALS-FTD spectrum, histopathologically characterized by the presence of hyperphosphorylated TDP-43 and other proteinopathies. The aim of this thesis was to characterize the demographic and genetic background, phenotypic manifestations of ALS and ALS-FTD, and the potential occurrence of other neurodegenerative diseases in the family history of ALS patients. The demographic profile and analysis of phenotypic manifestations were conducted based on patient clinical records and questionnaire surveys. A total of 184 patients were examined, 146 were genetically analyzed, and 78 questionnaires were processed. Regarding the genetic background characterization, the study focused on...

Clinical significance of the rs4646994 polymorphism in the ACE gene
BÍCHOVÁ, Simona
The present bachelor thesis deals, as it is obvious from the title, with one particular polymorphism rs4646994 in the ACE gene and its clinical significance. The ACE gene, consisting of 26 exons, is localized on chromosome 17q23 and its name ACE stands for angiotensin converting enzyme. This enzyme is capable of breaking down proteins and is part of the renin-angiotensin system, which regulates blood pressure and fluid and salt balance in the body. The principle is to split a protein called angiotensin I into angiotensin II. This then causes the blood vessels to narrow (constrict), leading to an increase in blood pressure. This protein also stimulates the production of the hormone aldosterone, which triggers the absorption of salts and water by the kidneys. The increased amount of fluid in the body subsequently increases blood pressure. In addition, angiotensin II may also play a role in kidney development. The selected ACE rs4646994 polymorphism is of great interest in terms of various diseases (e.g. COVID-19, nephropathy in diabetes mellitus, polycystic ovary syndrome, etc.) It may also play an important role in Alzheimer's disease, which is the focus of the practical part of this bachelor thesis. The investigation of the rs4646994 polymorphism in the ACE gene was carried out in a selected group of 61 patients with a diagnosis of dementia by end-point PCR. The data obtained were then statistically processed and compared with a control group of patients without a diagnosis of dementia. The results were then compared with available scientific publications.

Heredity of colouring in rabbits
HOZDOVÁ, Lenka
This bachelor thesis is focused on the practical verification of the laws of heredity in fur coloration during mating of rabbits Californian black rabbit and Viennese blue rabbit. Coloration of these breeds are white with black marks on the ears, nasal mask, legs and tail in Californian black rabbit and cloak blue coloration in Viennese blue rabbit. In subsequent generations there were also individuals discolored by either parent and were cloak black. According to the analysis of genotypes of both breeds, this phenomenon was anticipated and the further cross-breeding of the offspring of the F1 generation began to re-emerge from the individuals of the same coloration as the original two purebred breeds. Repeated crossings of parent breeds were carried out, as well as the crossing of F1 and F2 generations in different combinations. Based on the genotypes of the parents, the coloration of individuals of all types of litters was predicted and subsequently these ratios were verified by a mathematical method called "Chí quadrate test". All these ratios were consistent with the assumptions and the objective of the work was therefore verified.

Detection and variation of the crayfish plague pathogen in selected crayfish populations
Mojžišová, Michaela ; Petrusek, Adam (advisor) ; Buřič, Miloš (referee)
Crayfish plague is an emerging disease caused by the oomycete Aphanomyces astaci, a pathogen listed among the 100 World's Worst Invasive Alien Species. It was introduced into Europe in the second half of 19th century from North America and caused collapses of European native crayfish populations. Nowadays, A. astaci is widespread in Europe and has spread also to other parts of the world, threatening all susceptible crayfish of non-North American origin. The aims of this MSc thesis were 1) to provide information about crayfish plague outbreaks from recent years, and by using microsatellite and mtDNA markers reveal A. astaci genotypes involved; 2) to test healthy-looking indigenous crayfish for potential occurrence of chronic infections by A. astaci in Czechia. Six new crayfish plague outbreaks were confirmed from 2016 to 2018, involving at least five distinct pathogen strains. My results provide first evidence of the A. astaci genotype group D causing Astacus astacus and Austropotamobius torrentium mass mortalities in Czechia. MtDNA sequencing revealed two haplotypes of the D haplogroup, indicating two independent sources of infection presumably either from ornamental crayfish or spreading from neighbouring countries. The genotype group A was recorded in two A. astacus mortalities and genotype group...
