Possibilities of genetic testing in patients with pheochromocytoma and paraganglioma.
Turková, Hana ; Zelinka, Tomáš (advisor) ; Malík, Jan (referee) ; Fryšák, Zdeněk (referee)
1. Abstract Pheochromocytoma/ paraganglioma (FEO/PGL) may be developed on the basis of an inherited genetic mutation of different genes. They are associated with a high risk of developing of secondary hypertension, organ damage and metastatic disease that can be fatal. The aim was to focus on the possibility of genetic testing in patients with FEO/PGL, especially in patients with malignant tumors. The issue FEO/PGL, however, concerns not only the examination and assessment of risks arising therefrom, as well as other therapies and monitoring, including appropriate recommendations for clinical practice. We demonstrated a 20% incidence of cardiovascular (CV) complications before determining the final diagnosis of FEO/PGL, mainly arrhythmic, followed by complications of myocardial ischemia and accentuate atherosclerosis. Elevated levels of vitamin C and decreased levels of malondialdehyde (MDA) following the successful removal of the tumor demonstrated reduction of oxidative stress postoperatively. We found that early postoperative testing of levels of plasma metanephrines to confirm the success of surgical removal of FEO/PGL is already possible, since there was no significant correlation between plasma levels of metanephrines and postoperative examination interval. Distribution of frequency of metastatic...

Studium dědičnosti polyneuropatie u psů plemene leonberger
Wolfová, Anna
The main objective of this master thesis entitled The study of polyneuropathy in Leonberger dogs (LPN) was to determine the variability of ortholog of CMT2 gene in a selected population of this breed. The number of individual samples studied was 211. The entire set of DNA samples was divided to the cases (110 samples) and controls (101 samples). Partial objectives were the study of information available on the hereditary neuropathies, the selection of candidate gene polymorphisms and their association analysis with the disease. The candidate gene studied is associated with the autosomal recessive form of axonal neuropathy in humans with early onset of symptoms. Compound mutation was discovered in the gene (substitution and 1 bp deletion). The normal allele predominated in healthy individuals. In contrast, both mutant alleles always predominated in diseased individuals. Statistical comparison of genotypes depending on the health status did not show a clear correlation with disease (p = 0,1562).
