Detekce fytopatogenů jahodníku
MICHÁLKOVÁ, Barbora
Strawberries were tested for presence of selected phytopathogens (Agrobacterium, Rhodococcus, phytoplasmas, SMYEV, SMoV, SPV1, SCV and SCRh1) by the PCR. At the same time was researched the transmission of mentioned phytopathogens by grafting. The DNA of the strawberries with positive results was sequenced.
Examination of the polymorphism of the gene ApoE
NOVOTNÁ, Tereza
Alzheimer´s disease (AD) belongs to the most frequent cause of dementia in the world. It is determined that it is about 65-75 % of all the dementias (Preiss, Přikryková Kučerová, 2006). The term Alzheimer Dementia, as well as Pre-senile Form (AD) is used with the patients at the age up to 65 years (Seidl, 2015). After the age of 65 years we use the term Senile Dementia of the Alzheimer Type. (SDAT). Up to the age of 45 this desease is rare (Seidl, Obenberger, 2004). Causal treatment of this disease does not exist, because etiopathogenesis of the disease is not entirely clarified (Seidl, 2015). The aim of this bachelor´s work was to write a professional search to the given topic. In this theoretical part there is summed up the information about neurodegenerative disease, about dementia and (AD). Most importantly there are described the symptoms, the causes, phase, treatment, diagnostics and genetic disposition of AD. The description of polymerase chain reaction (PCR) and reverse hybridization on strips is also an important part of this theoretical part. In the practical part, the main goal was to master molecular biological methods. To achieve the goals and to get the best results, I chose two methods. In addition to optimizing the PCR ARMS method, reverse hybridization was used on strips. The above-mentioned second method was performed using the commercially available ApoE StripAssay? kit from ViennaLab. In this part of the paper are described all the procedures by which I achieved the results. Molecular biological methods were performed in a laboratory at the Health and Social Faculty of the University of South Bohemia in České Budějovice.
Epitachophoretic separation and concentration of large volume samples
Voráčová, Ivona ; Foret, František ; Datinská, Vladimíra ; Novotný, Jakub ; Gheibi, P. ; Berka, J. ; Astier, Y.
There has been a growing interest in developing isotachophoretic protocols for concentration and purification of DNA as an alternative to the solid phase extraction protocols of DNA preparation. Also concentration of DNA from large volume samples is required. We have developed a new device suitable for separation, concentration and collection of ions from several milliliter sample volumes into microliter fractions. We have used a discontinuous electrolyte system comprising of the leading and terminating electrolytes utilized for concentration of samples containing DNA fragments. The method is simple, fast with high concentration factor and without extensive surface interactions.
Genetic markers for monitoring post-transplant chimerism
Řehounková, Michaela ; Beránek, Martin (advisor) ; Matoušková, Petra (referee)
Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Biochemical Sciences Candidate: Bc. Michaela Řehounková Supervisor: doc. PharmDr. Martin Beránek, Ph.D. Title of diploma thesis: Genetic markers for monitoring post-transplant chimerism The aims of the thesis: Data processing of patients, who underwent allogenic hematopoietic stem cell transplantation in a period from 2010 to 2014 in University Hospital Hradec Kralove and whose state of chimerism was monitored at the Section of Molecular Biology at the Institute of Clinical Biochemistry and Diagnostics. Consequently, analysis of the possible relationship between selected clinical parameters and used genetic markers for chimerism quantification was carried out after the processing of acquired data. Finally, the possible influence of treatment success and mortality by chosen clinical parameters was evaluated. Methods: Analysis of short tandem repeat loci, which uses genetic variability between donor and recipient of transplanted graft, was employed for quantification of post- transplant chimerism. DNA of donor and recipient was isolated by QIAmp DNA Blood Mini Kit (QIAGEN, Germany), amplified by AmpFlSTR Identifier Kit (Applied Biosystems, USA) and separated by capillary electrophoresis (analyzer ABI 3130-4, Applied...
Current questions on specific DNA determination : possibilities of effective use in agriculture and food industry: 11.12.2009
Ovesná, Jaroslava ; Pouchová, Vladimíra
Research into the genetic variability of economically significant crops brings new opportunities to improve their biological potential. This seminar focused on the possibilities of some procedures, their use for gene characterization and genetic expression in important crops such as wheat and barley, as well as minor crops such as garlic and hemp, where there is not enough data available on the sequence of genes. Also practical applications of the obtained results have been shown as well as sampling procedures.

Melting of a methylated CpG-containing DNA double helix
Bušková, Hana ; Římal, Václav (advisor) ; Hanyková, Lenka (referee)
The melting of a DNA double helix into two single strands is a crucial process for life on Earth. Previous experimental data on the self-complementary sequence CTTm5 CGAAG containing 5-methylcytosine suggests that the melting of an oligonucleotide might be a three-state, rather than two-state process. To assess this, 1 H NMR spectra were measured at varied concentrations of the oligonucleotide in temperatures between 274 and 366 K. Through analysis of the chemical shifts of aromatic hydrogens undergoing fast chemical exchange, we have determined that the most likely intermediate state between a double helix and a single stranded random coil is a structure consisting of two oligonucleotide molecules rather than a structured single strand.
NMR Study of Oligonucleotide Structures

Title: NMR Study of Oligonucleotide Structures Author: Václav Římal Department: Department of Low-Temperature Physics Supervisor: Prof. RNDr. Helena Štěpánková, CSc., Department of Low- Temperature Physics Abstract: The dynamics of nucleic acids plays a fundamental role in the interactions with proteins. Some processes are governed by changes in DNA stability and flexibility caused by sequence alterations or chemical modifications without substantial structural impact. We employed line-shape analysis of variable-temperature 1H NMR spectra to deeply investigate the melting transition of DNA structures. We observed a significant influence of the sequence beyond the nearest neighbours on chemical shifts and thermodynamics of the double helix. The CpG motif is especially sensitive to its distant surroundings and for a particular oligonucleotide it was even found to undergo an unexpected local conformational transition. A strong cooperativity in the duplex dis- ruption was witnessed by both the equilibrium and kinetic aspects as well as by distant effects of cytosine methylation. We propose a two-state melt- ing scheme also for a fragment of a transcription element proved here to fold as a hairpin with a six-membered loop. In addition, we describe the properties of self-assemblies of riboguanosine and...

Theoretical part of the thesis deals with basic concepts such as bacterial genome, comparative genomics and mainly synteny blocks. Here is explained what synteny is and what is its importance. In the theoretical part, the GenBank format is also mentioned, its content and usage. The practical part is focused on searching similarities in DNA sequences of reference bacteria with selected bacteria, their sorting by means of greedy algorithm and visualization of similarities using phylogenetic tree.
