New diagnostic and therapeutic aspects of inflammatiory cardiomyopathy
Kuchynka, Petr ; Šimek, Stanislav (advisor) ; Krejčí, Jan (referee) ; Gregor, Pavel (referee)
Introduction: Inflammatory cardiomyopathy (DCMi) represents a non-familial form of dilated cardiomyopathy (DCM) and endomyocardial biopsy (EMB) is crucial for its diagnosis. Aims: To assess the prevalence of DCMi in patients with DCM of unclear origin, to evaluate the significance of serological tests for antibodies against infectious cardiotrophic agents and to analyze the effect of specific therapy guided by EMB results. Methods: EMB was performed in 56 subjects (mean age 52 ± 10 years) with DCM of unclear etiology and left ventricular (LV) ejection fraction (EF) < 40% with a history of heart failure less than 1 year. EMB samples were analyzed by immunohistochemistry, polymerase chain reaction (PCR) and electron microscopy. Results: Immunohistochemical examination revealed myocardial inflammation in 26 patients (46%), the PCR method detected genome of microbial agents in 32 patients (57%). Electron microscopy showed the presence of particles of microbial agents in 41 patients (73%). Serological blood tests found no IgM antibody positivity against any of the investigated microbial agents. Targeted antibiotic therapy in patients with evidence of Borrelia burgdorferi (Bb) genome in the EMB led to a reduction in LV size, improvement of LV EF and alleviate symptoms of heart failure. Conclusion: DCMi...

Czech regulation of limited companies from the point of view of the 'law and economics' school
Šimek, Stanislav ; Pelikán, Robert (advisor) ; Černá, Stanislava (referee)
Czech regulation of limited companies from the point of view of the 'law and economics' school Abstract Law and economics has a potential to provide us with an uncommon and to the Czech jurisdiction often neglected point of view on laws. The aim of this paper is to apply economic theories on directors' liability for breach of fiduciary duties and to consider its consequences on the economic efficiency of companies. The critical question is whether not having such liability could provoke an increase of wealth of all stakeholders. The paper also aims to come up with instruments capable of minimizing the lost caused to companies by mandatory rules regarding director's liability. At the end of the thesis, the Czech laws regarding the director's liability for breach of fiduciary duties are analyzed in the point of view of economic analysis. The analysis is followed by proposition of instruments that could make companies operating in Czech legal environment more effective. Directors' liability, which can result in an aversion to make risky decisions, can cause significant losses to companies (so called agency costs). For that reason, the possibility to determine the scope of director's liability given to shareholders can have, in some cases, positive effect on the company's efficiency. The paper concludes that...
