Matějka, Jan ; Vojáček, Jan (advisor) ; Gregor, Pavel (referee) ; Červinka, Pavel (referee)
Contrast-induced acute kidney injury in high risk patients undergoing invasive cardiac procedures Introduction: Acute renal function impairment associated with radiologic procedures, known as contrast-induced acute kidney injury (CI-AKI), is strongly associated with a higher rate of morbidity, in-hospital mortality and diminished long-term survival. CI-AKI prevention focuses mainly on adequate periprocedural hydratation and use of a low amount of contrast media. Previous trials concerning use of adenosine antagonist theophylline revealed contradictory results. Goals: Our interventional trial sought to evaluate the effect of theophylline in CI-AKI prevention in well hydrated elderly patients with chronic kidney disease. Our cross-sectional study focused on CI-AKI in patients undergoing primary PCI for ST segment elevation myocardial infarction (STEMI). Methods: Interventional trial: randomized, double-blind, placebo-controlled trial was performed. 56 patients with estimated glomerular filtration rate bellow 60 60 ml/min/1.73m2 referred for cardiac coronary angiography and/or angioplasty were enrolled. 31 of them were randomly assigned to 200 mg theophylline IV before procedure, and 25 to placebo. Iso- osmolar contrast Iodixanol was used. Trial protocol included mandatory parenteral hydration. The...

Determination of the efficiency of solar collectors covered makrolon plates.
MATĚJKA, Jan
This thesis deals with the alternative cover of the liquid solar collector. It describes the structure of the solar collector itself and the influence of various parameters that directly affect its effectiveness. It analyses technical - economic possibilities of the usual type of the glazing and compares them with possibilities to cover the collector with the makrolon plates. The aim is to perform a theoretical evaluation to find out whether the referenced type of covers, due to its characteristics, could be used. In conclusion the evaluation of values and possibilities of its practical use are shown.

Public debts in the world - analysis of public finances focusing on G-20 countries
Matějka, Jan ; Jílek, Josef (advisor) ; Běláčková, Vendula (referee)
This thesis deals with the problem of public debt within the G-20 countries and the Czech Republic. The current state of public finances in these countries was analyzed through the so called Public Finance Checklist, which has been specifically developed for this thesis. The Checklist includes some public sector liabilities that are not a part of the conventional analysis of public sector debt. The results of analysis show that hidden liabilities constitute a significant part of the total amount of public debt in the analyzed countries. This fact presents a threat to stability of public finances. While the total public debt is increasing, governments aim to optically decrease the level of debt. The author assumes that the reason for such behavior is the arrangement of political system with missing corrective mechanisms of the principal-agent problem and moral hazard put into effect by political representatives. At the end of the thesis the author suggests some methods to fix the problems and restrict the growth of public debt.

One of the main aims of this work was also to compare some terms in the Directives and the Act. The author also tried to discuss several controversial and not very appropriate legal implementations in the Czech Republic.
