Large artery properties in primary and secondary - endocrine hypertension
Rosa, Ján ; Widimský, Jiří (advisor) ; Mlíková Seidlerová, Jitka (referee) ; Špinar, Jindřich (referee)
Arterial stiffness represented by carotid-femoral pulse wave velocity (PWV) is considered to be an independent cardiovascular risk factor. This study was focused on large artery properties investigation in specific forms of hypertension using applanation tonometer Sphygmocor (Atcor Medical). PWV was significantly higher in resistant hypertension patients when compared to moderate essential hypertension (EH) patients. This difference appears to be independent of clinical blood pressure (BP). Night-time BP appears to be a more accurate predictor of PWV in EH. In another study we demonstrated that primary hyperparathyroidism (PH) (both hypertensive or non-hypertensive forms) might be associated with higher PWV when compared to EH patients or to normotensive controls and that this difference is independent of age and clinical BP. Neither calcium serum level, nor parathyroid hormone has been associated with PWV. Specific treatment by parathyroidectomy (PTX) seems to be beneficial for PWV decrease, which might be mainly determined by improved BP control after surgery. Since PTX indications for asymptomatic forms of PH have been discussed, our data suggest the potential benefit to the extent of subclinical organ damage after surgical treatment in these patients. Similarly, we prooved higher PWV in...

Fungal parasites as a factor affecting the dynamics of microalgal communities
Rosa, Jan ; Šťastný, Jan (advisor) ; Pichrtová, Martina (referee)
This bachelor thesis deals with fungal parasites which are an important factor that affects the dynamics of microalgal communities. Here I sum up the knowledge of parasites especially from Oomycota and Chytridiomycota along with a little focus on other groups. The basic characteristics of these fungal parasites, such as their host specificity and factors that affect their spreading ability between algal hosts, are summarized. The abiotic factors such as light and temperature, which are the most important factors causing epidemic, are mainly discussed. The fungal parasites can change the maximal population size and are able to alter the competitive relationships in microalgal communities. These factors are discussed in individual algal groups. The fungal parasites could be a negative economic player of the bioindustry and their future role in this industry is also discussed. Key words: parasite, host, host specificity, communities dynamics, algae, fungi, phytoplankton
