Gene expression pattern in the adult brain of the experimental rat after prenatal exposure to methamphetamine
Tomášková, Anežka ; Černá, Marie (advisor) ; Rudá, Jana (referee)
Introduction: Methamphetamine is a drug frequently taken by drug-addicted pregnant women and happens to be one of the most commonly used drugs in the Czech Republic. This drug passes easily through a placental barrier into the fetus. Thus it can negatively affect not only the mother but also the prenatal development of her offspring. Objectives: This research aims to provide a general screening of gene expression in selected regions of the F1 generation of the brain prenatally affected by methamphetamine, to verify whether exposure to methamphetamine affects the generation of offspring of exposed females at the level of gene expression in selected regions of the brain, and to valuate possible changes in gene expression. Methods: In selected parts of the brain, collected from a rat, the microarray hybridization and the real-time PCR were set to evaluate express changes in the expression of selected genes. Results: Statistical analysis of the microarray hybridization did not show a significantly altered gene expression in the tested genes. Only boundary values for 13 genes were measured, which were further tested by the real-time PCR. After a statistic evaluation of the real-time PCR, the significantly altered expression was found in 2 genes. The notably changed expression of DRD3 and TACR3 genes...

Mapping of psychosocial interventions and attitude of workers in selected low-threshold contact center to methamphetamine users
Mištová, Anna ; Brenza, Jiří (advisor) ; Matoušek, Petr (referee)
INTRODUCTION: Despite the unique status of methamphetamine on the Czech drug scene, where the number of problem MA users accounts for 3/4 of all problematic drug users, there is a minimal amount of literature in the literature on how to work with this target group in the addictological care system. OBJECTIVE: The practical part was to monitor the work and access to methamphetamine users in the selected k-centers. Attention was paid to presenting KC clients, perception of key motives in each phases of drug use trajectories, the process of working with clients from first contact to eventual mediation of treatment and description of the specifics of access to MA users. METHOD: The chosen sample was selected on the basis of deliberate targeted selection through the institution. The data were collected by semi-structured interview, which was fixed with audio recording and subsequently transcribed. The patterns capture method as used to analyze the data. FILE: The research sample consisted of eight communication partners (four men). They were employees of selected k-centers, always one worker per facility, from different regions of the Czech Republic, with various length of experience in field (2,5 to 16 years). RESULTS: KC clients are mostly MA users, often polyvalent users, combining MA with other...

Prenatal exposure to methamphetamine and its effect on the gene expression in the selected parts of the brains of experimental rats
Tomášková, Anežka ; Zoubková, Hana (advisor) ; Rudá, Jana (referee)
Introduction: Methamphetamine is a drug frequently abused by drug-addicted pregnant women and also one of the mostcommonly used drugs in the CzechRepublic. This drug passes easily through a placental barrier into the fetus. Thus it can negatively affect not only the mother but also the prenatal development of her offspring. Objectives: In the framework of the grant project GA CR: 14-03708S, the long-term effects of prenatal exposure to methamphetamine were detected. It was determined whether the prenatal methamphetamine exposure affects the generation of offspring of exposed females at the level of gene expression of genes in specific regions of the brain, striatum, hippocampus and prefrontal cortex. Methods: In the selected parts of the brain, which were removed from the rat, the microarray hybridization and the real-time PCR to express changes in expression of selected genes were performed. Results: Statistical analysis of microarray hybridization did not show the significantly altered gene expression in tested genes significantly. Only boundary values for 13 genes were measured, which were further tested by real-time PCR.After a statistic evaluation of real-time PCR, the significantly altered expression was found in 2 genes. The significantly changed expression of DRD3 and TACR3 genes was found...
