The Islamist movements operate in all the countries of the Middle East and North Africa region. The mother organization, which is also best-known among the movements, is the Muslim Brotherhood in Egypt, whose ideas spread quickly into other countries in the region. Although the Islamist movements are ideologically different, they have one similar attribute - focus on various social issues as well as the fact that they originally profiled as charity organizations and they have only recently entered the political scene. The main goal of this diploma thesis is to analyze and compare the activities and achievements of the Muslim Brotherhood (The Freedom and Justice party) and The Movement of Islamic Tendency (The Ennadhda party) within the political systems in Egypt and Tunisia. The thesis also aims at verifying explanatory cleavage of Islamist electorate based on the cleavage theory within Egypt and Tunisia. The biggest success of the Islamist movements so far meant the changes after the Arab Spring. Following this event the Islamist movements won the first free parliamentary election in both countries. However, the political activities of the Muslim Brotherhood did not last so long in Egypt - nowadays the movement exists only illegally and it has been in a difficult position. On the contrary, the...

(v anglickém jazyce) Development of tooth primordia in mice is an important model for study of odontogenesis. Several dental rudiments develop during the mouse embryogenesis. These structures develop in functional teeth in their phylogenetically older relatives. Similarly, we can initiate growth of teeth from these germs in some mutant mice. In my diploma thesis we have focused on the importance of rudimentary structures with odontogenic potential in postnatal individuals. As a model of development, we have chosen a cell population originating from rudimentary primordia MS (mesial segment) that develops in diastema of the lower jaw during the embryonic day 12.5. Using the inducible Cre-lox technology we have marked the cells which are part of the signal domain of primordia at this time. As a marker of these cells we have used gene Shh. We have found out that these cells persist prenataly and also postnatally. Further we have isolated this cell area and we have tested it using a variety of methods. We have shown that in the cells of postnatal individual are expressed markers of stem cells (Sox2, Bmi1, Gli1) and also genes for major enamel matrix structural proteins: ameloblastin and amelogenin. The same stem cell markers are also expressed in vitro culture of the isolated cells. This cell population...
