Mobile Switching Centre Emulator
Králíček, Jan ; Ráb, Jaroslav (referee) ; Ščuglík, František (advisor)
This thesis attempts to provide basic overview of the topic of the GSM system and tries to design Mobile Switching Centre Emulator that could perform the operation Location Update. The first part of this thesis describes the principles and specifics of the GSM network (network structure, the operations required to support user mobility, network entities, etc.). The second part of this thesis describes the SS7 signaling protocols, SIGTRAN and MAP protocol. The final part deals with design of the emulator.

Home Location Register Emulator
Juránek, Michal ; Ráb, Jaroslav (referee) ; Ščuglík, František (advisor)
This thesis presents basic structure and entities of mobile network GSM. It presents principles of signalling with focus on core network via signalling systems SS7 and SIGTRAN. Chosen protocol layers and signalling message types are presented. The thesis is concluded by the design and implementation of the application emulating home location register of mobile users.

Pathogenesis of hypercholesterolemia in Prague hereditary hypercholesterolemic (PHHC) rat
Rybáková, Kateřina ; Vlachová, Miluše (advisor) ; Poledne, Rudolf (referee)
Hypercholesterolemia represents a major risk factor of cardiovascular disease. A number of experimental models is used for study of hypercholesterolemia pathogenesis and therapy. This thesis concentrates on characterization of one of these models. Prague hereditary hypercholesterolemic (PHHC) rat is such a suitable model for study of hypercholesterolemia. Although the majority of plasma cholesterol is transported by high density lipoprotein in PHHC rat fed standard diet, PHHC rat fed cholesterol diet develops hypercholesterolemia comparable to that of humans. The advantage of this model is that hypercholesterolemia develops without the need for addition of bile acids or other hepatotoxic substances to the diet. The hypercholesterolemia of PHHC rat is caused by slowed down catabolism of cholesterol-rich very low density lipoprotein (VLDL). These cholesterol-rich particles are synthesized in the liver. We found out that PHHC rat fed 1% cholesterol diet accumulates cholesteryl esters (CE) in the liver and also in the VLDL. Acyl-CoA:cholesterol acyltransferase (ACAT) and microsomal triglyceride transfer protein (MTP) may participate in the increased incorporation CE into VLDL. We found out no difference in ACAT and MTP activities in the liver between PHHC rats and control animals. Neither ACAT activity...
