4 Abstract Introduction Since 2016, we know that the neuron responds to chronic hypoperfusion by reducing its performance. Cerebral revascularization using extra-intracranial bypass in internal carotid occlusion has also been shown to improve this reduction in function. In the case of asymptomatic internal carotid stenosis (ACS), hypoperfusion of the brain may occur due to insufficient collateralization. It is not clear whether this condition can lead to changes in cognitive performance. Likewise, the impact of hemodynamic changes on cognition in patients with ACS after carotid endarterectomy (CEA) remains unclear. The aim of this study was to evaluate the results of CEA for ACS at one year by assessing the changes in anterior, middle, and posterior cerebral artery blood flow in tandem with changes in cognitive efficiency. Methodology As part of the prospective study, the flow volume in cerebral arteries using quantitative magnetic resonance angiography was measured in a group of 14 males and 5 females before and at one year after CEA for ACS. Cognitive efficiency was assessed by Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). The values of flow volume were processed using simple ratio (SR) and were used for analyses with changes in cognitive skills after CEA. Results One year...

Propaganda and media image of right–wing extremism
Košťál, Petr ; Macků, Lucie (advisor) ; Fajfrlíková, Pavla (referee)
The aim of thesis "Propaganda and media image of right-wing extremism" is analyze media activities of right-wing extremism and find out what image of Czech right-wing extremist scene was created by two the most read Internet news portals, Novinky.cz and iDNES.cz. The theoretical part defines the concept of propaganda, media, introduces the Czech right-wing extremist scene and history of right-wing extremist groups. The theoretical part allows orientation in the topic.
The practical part uses the methods of quantitative and qualitative analysis. By quantitative methods is explained what attention is dedicated to Czech red-wing extremism by internet news portals. The method of qualitative analysis determines what is the media image of the Czech right-wing extremism groups and how was that image changed since 2011 until the end of 2015.
