Biocompatibility of porous NCD layers with neurons
Freislebenová, Hana ; Benson, Veronika (advisor) ; Rudajev, Vladimír (referee)
Nanodiamond is currently one of the most researched materials in the field of regenerative medicine in the study of treatment of neurodegenerative diseases. Due to direct interaction of this material with nerve tissue, it needs to be biocompatible with primary neurons. Furthemore, it is desirable for the used material to induce cell adhesion and stimulate the adherent cells to regeneration. This work evaluates the biocompatibility of porous boron-doped diamond layers with the culture of primary neurons. We compared the effect of diamond surface treatment by poly- D-lysine (PDL) coating on the adhesion and prosperity of the primary neuronal culture. We found that the tested nanodiamond layers are biocompatible with the primary neuronal culture. We further conclude that the PDL coating slightly increases the rate of cell adhesion to the surface but on the other hand induces greater adhesion of glial cells than the surface without PDL coating. Key words: nanodiamond, biocompatibility, adhesion, neurons

Behavioral testing of animals after experimental spinal cord injury.
Freislebenová, Hana ; Machová Urdzíková, Lucia (advisor) ; Kriška, Ján (referee)
Spinal cord injury is one of the most serious injury that leads to a decrease in the quality of life both physically and mentally. Although there is currently no effective treatment, great efforts are being made to develop new treatments. The effectiveness of experimental treatment is verified by behavioral tests performed on animal models, where rats are the most suitable ones for this type of injury. Behavioral tests are divided into several groups depending on what the testing is focused on. Locomotor tests examine the function of a locomotive apparatus, motor tests are used to determine the function of skeletal muscles not primarily involved in locomotion, sensory and motor tests test the functionality of sensory and motor apparatus and their interconnection, sensory tests are designed to test responses to sensory stimuli. Electrophysiological tests and functional magnetic resonance imaging are part of a series of special tests that use artificially induced electrical stimuli to measure muscle activity. This thesis is focused on detailed description of selected behavioral tests, their functionality and comparison of their advantages and disadvantages.

Methods for assessment of proinflammatory cytokines
Freislebenová, Hana ; Lašťovička, Jan (advisor) ; Hájková, Michaela (referee)
Sepsi and septic shock are the leading causes of death in intensive care units worldwide. Cytokines are important regulators of the immune response, which have crucial role in sepsis pathofysiology. This work deals with proin flammatory cytokines mainly interleukin 1, interleukin 6 and TNF-α and methods of their assessment. The purpose of this work is to compare immunohistochemis try methods like ELISA and ELISPOT with assessment of intracellular cytokines by flow cytometry.
