QoS Implementation in Access Network
 Adámek, David ; Molnár, Karol (referee) ; Filka, Miloslav (advisor)
This diploma thesis deals with computer networks which play a key role in present society. More and more demands are placed on these networks (especially on quality of services and throughput) because of fast-growing developement of services such as voice and video real-time transmissions. All the packets in typical Ethernet networks are equal. Therefore it is sometimes impossible for the application to maintain required throughput speed of a network. For this case it is useful to take some mechanisms into the consideration. These mechanisms (sometimes called QoS) are able to distinguish different types of transmissions and traffic, analyze them and then prioritize them according to some pre-defined set of rules. The most famous mechanisms are Integrated Services and Differentiated Services. The implementation of Differentiated Services is the goal of this thesis.

The role of NETosis in pathogenesis of autoimmune diseases
 Pošmurná, Eliška ; Brynychová, Iva (advisor) ; Šolc, Roman (referee)
Neutrophil granulocytes - white blood cells are very effective in fight against pathogens with fagocytosis, degranulation, or NETosis, which is special form of cell death. During NETosis are created neutrophil extracellular traps, which can trap and destroy microorganisms with antimicrobial granules. NETosis can be iniciated by activation of pro-inflammatory cytokines, lypopolysacharides or phorbomystatic acid. Activated neutrophils get to the site of inflammation, where decondensed chromatin, part of NETs, gets into extracellular space. DNA in extracellular space is strong alarmin for immune system as part of NETs. Increased NETs production or problem with their elimination can play role in patogenesis of some autoimmune diseases (eg. Systematic lupus erythematodes, associated vasculitis, rheumatoid arthritis, diabetes mellitus). NETs production or their components can affect diseases or degree of damage to the surrounding tissue. It also correlates with seriousness of disease (eg. Associoated vasculitis) and can have diagnostical potencial (eg. Asociated vaskuloitides, rheumatoid arthritis or diabetes mellitus type 1). Keywords: NETosis, NETs, neutrophils, autoimmune diseases, immune system
