Application of renewable and recyclable raw materials for preparation of new polymers
Horák, Pavel ; Beneš, Hynek (advisor) ; Cajthaml, Tomáš (referee)
This thesis deals with optimalization of flexible polyurethane foam recycling with using of natural polyols based on rape seed oil and fish oil and it explores applications of depolymerized polyol product by formulations of new polyurethane materials. The experiments of depolymerisation showed that both tested natural oil (rape seed oil and fish oil) can be used as effective reagents for polyurethane recycling. Reaction conditions of depolymerisation were optimised with model flexible polyurethane foam and applied on waste foam from real conditions. Gain of depolymerisation is one-faze low viscosity (to 1500 mPa.s) liquid polyol products with content of hydroxyl groups ca 3 mmol/g. These polyols can be used for polymerisation of new materials. First application of recycled polyols was formulation of polyurethane foam systems. Through optimising of formula was prepared low-density semirigid foam containing 100 percentage of recycled polyol. Properties of these foams correspond to commercial foams. To prepare of homogenous cast polyurethane system based on recycled polyols it was necessary to add proper solvent, therefor extent of application has been lowered. On that account the systems were tested for study of polyaddition reaction and for following properties of the material. In these tests, the reactivity...

New cytokines in the pathogenesis of rheumatic diseases
Filková, Mária ; Šenolt, Ladislav (advisor) ; Hrnčíř, Zbyněk (referee) ; Horák, Pavel (referee)
Background: An imbalance between pro- and anti- inflammatory cytokine activities favors the induction of autoimmunity, chronic inflammation and joint damage in patients with rheumatoid arthritis (RA). Adipokines are bioactive proteins that are important regulators of inflammation. IL-35 is a new cytokine involved in the inflammatory processes in mouse models and is of unknown function in humans. The aim of the work was to study the levels and role of several adipokines and IL-35 in the joint and blood compartment and the association with the disease activity in patients with RA or other rheumatic diseases. Results: We found increased levels of adiponectin in serum of patients with erosive osteoarthritis (OA) of the hand, differential regulation of new adipokines vaspin and omentin in synovial fluid of patients with RA compared with OA and the effect of therapy using TNFα inhibitor on the expression profile of adipokines in subcutaneous adipose tissue of RA patients. B cell depletion therapy in RA resulted in decrease of serum levels of visfatin that correlated with following change of disease activity. The levels of IL-35 in synovial fluid are significantly higher in RA than in OA and correlate with the disease activity and functional status. IL-35 subunits p35 and EBI3 are overexpressed in RA...

progressive trends in energy exploitation of fossile fuels
Horák, Pavel ; Přibil, Rudolf (advisor) ; Matějíček, Luboš (referee)
This paper, as literature retrieval, evaluates progressive trends in development of technologies for energetic use of fossil fuels. The introduction is focused on reasons for increase of energetic efficiency of combustion processes, especially reasons for using of fossil fuels and their consumption over the world and in Czech Republic. Next chapter focuses on mainly used fossil fuels, which means coal, crude oil and its derivatives and natural gas. Those are evaluated in term of quality and historical progress, too. Fundamental chapter analyses particular improvements but also complex technologies used in energetic, for example using of gas turbines, assets of Kalina cycle, complex technology of Integrated Gasification Combined Cycle (IGCC), combined heat and power production (CHP), combined cycle gas turbine (CCGT) or pressurised fluid bed combustion (PFBC).

Social demokratic publicists in the post-February exile (1948-1953)
Horák, Pavel ; Čechurová, Jana (advisor) ; Sekera, Martin (referee)
This diploma thesis (Journalism of Social Democratic Exile after February 1948 /1948- 1953/) studies the history of social democratic party in exile between the years 1948 and 1953 with special focus on journalism, news service and propaganda. The thesis describes formation of party fractions and deals with how they defined themselves, communicated and presented themselves in the media. The thesis then goes on to analyse the newspaper format, production and financing thereof as well as the number of copies. It looks into broadcasting activities of social democrats and their plans related to the setup of illegal radio. Based on the cases of party secretary Vilím Blažej and Bohumil Laušman, the last party chairman prior to February 1948, the thesis analyses the question whether single groups within the party in the given time period tried by its journalistic activities to primarily influence events in Czechoslovakia or whether these efforts slowly faded due to rivalry between fractions and frustration over hopeless political situation and lack of audience in such an extent that media outputs were later on confined only to discussions within the party and to barely expressing political views.

The influence of some factors on renal impairment in AA amyloidosis
Potyšová, Zuzana ; Ryšavá, Romana (advisor) ; Monhart, Václav (referee) ; Horák, Pavel (referee)
Introduction: Available data suggest an association between presence of secondary (AA) amyloidosis and MCP-1 (monocyte chemoatracttant protein-1) and MIP-1alpha (macrophage inflammatory protein-1 alpha) genes polymorphisms. Some studies have also shown an impact of polymorphisms in exon 3 of SAA 1 (serum amyloid A 1) gene on the incidence of AA amyloidosis in different populations. Methods: The incidence of single genotypes MCP-1, MIP-1alpha and SAA 1 genes was investigated. Serum levels of SAA, MCP-1 and MIP-1alpha were measured and potential relation between serum levels and genotypes were analyzed. All examinations were performed in patients with AA amyloidosis (43), rheumatoid arthritis (RA) without amyloidosis and healthy control group (100). Results: Significantly more frequent occurrence of 1.1/1.1 genotype in SAA 1 was recorded in AA amyloidosis group compared to RA group as well as in control group (p<0,001). No statistically significant differences in distribution of another genotypes were found. Distribution of neither 1.1/1.1 genotype nor another ones did not vary among RA group and control group. No significant difference in distribution of another examined genotypes was recorded among all three groups. Serum concentrations of SAA were statistically significantly higher in AA amyloidosis group...

Political ideas of Bohumil Laušman - story of the democratic socialist
Horák, Pavel ; Čechurová, Jana (advisor) ; Gebhart, Jan (referee)
Bohumil Laušman (born August 30th, 1903) was a member of the Social Democratic Party. He was elected member of the National Assembly for the Pardubice region after ten years in regional politics. At the age of thirty-one he became the youngest Member of Parliament. He organised the foundation of the second parliament formation after the Munich events within the system of limited democracy, the National Labour Party. Not only did he show courage, he also showed sense for reality, when he was regulating some left-wing radicals in the weak party. He participated actively in the resistance after the establishment of the protectorate. In his resistance, he promoted collaboration across the political spectrum. That is why the selfconfident Laušman entered the exile with the idea that the left-wing party should have a moral right to determine political direction of exile institutions, which were forming at that time. His obvious left-wing tendency and non-constructive behaviour are possible to be seen after the failure of his political formation of Czechoslovakia's resistance movement in Paris and London. He travelled to the USSR in the middle of the year 1942 to get acquainted with political ideas of the representatives of the Czechoslovak resistance residing there, possibly to get their political support. During...

2Adherence to Osteoporosis Treatment
Vytřísalová, Magda ; Vlček, Jiří (advisor) ; Horák, Pavel (referee) ; Macek, Karel (referee)
Literature search Introduction: Osteoporosis (OP) is an important non-communicable disease, the incidence of which is increasing. It is a systemic metabolic skeletal disease characterized by reduced bone mass and changes in bone tissue quality. These disorders increase the risk of fracture and consequently have a considerable impact on public health. OP affects primarily postmenopausal women, but has recently become a great concern in men as well. Among the most important preventive (and non-drug therapeutic) interventions are a diverse diet high in calcium, adequate physical activity, avoidance of exposure to toxic substances and fall prevention. Multiple therapeutic strategies are used in attempts to restore balance between the bone resorption and the bone formation. A first-line intervention is calcium and vitamin D supplementation. Specific drug therapies (anti-osteoporosis drugs) are classified according to the predominant mechanism of action into anticatabolic or antiresorptive drugs (bisphosponates, raloxifene, calcitonin) and formation stimulating, anabolic drugs (parathormones), and drugs with a dual mechanism of action (strontium-ranelate). The current treatment strategies reduce the risk of fracture by about half and have proved cost effective. As in other chronic asymptomatic diseases,...
