Multi functional milling cutter and CNC machines with rating.
Leden, Pavel ; Zemčík, Oskar (referee) ; Kalivoda, Milan (advisor)
This thesis is focused on milling cutters for CNC machines which create integral branch of modern machining method. Thesis is divided into individual sections from choose of method and tool to choose of principles of work holding. The attention is mainly focused on assortment of milling tools. At the close of this thesis there are mentioned some practical examples from the manufacturing process in selected engineering firms.

Body manufacture of a key lock
Leden, Pavel ; Madaj, Martin (referee) ; Kalivoda, Milan (advisor)
The diploma thesis is focused on the production of body for cylinder locks. This is production of very small and accurate parts. In the first part there is described the function of the lock, the sort of cylinder locks, their components and the basic types of safety elements. The second part is focused on the production of given type of body. The thesis deals with either existing production technology or proposals of possible innovation. This firstly consists in new organization of manufacturing operations. At the close we can find comparison of existing technology and new proposal.

Inflammation and peripheral metabolism of glucocorticoids
Leden, Pavel ; Kment, Milan (advisor) ; Hampl, Richard (referee) ; Kršek, Michal (referee)
10 Abstract Glucocorticoids play an important role in regulation of inflammation and their immunosuppressive effect is widely used for treatment of inflammatory diseases. The biological activity of glucocorticoids depends not only on their plasma concentrations, the number of receptors and the responsiveness of the target cells but also on the local metabolism of glucocorticoids that is predominated by 11β-hydroxysteroid dehydrogenase (11HSD). Two isoforms of 11HSD are known. The isoform 11HSD1 operates in vivo predominantly as a reductase that increases the local concentrations of glucocorticoids by reduction of their 11-oxo derivatives. The isoform 11HSD2 is a pure dehydrogenase that inactivates biologically active glucocorticoids to their inactive 11-oxo derivatives. The published data concerning peripheral metabolism of glucocorticoids during inflammation were obtained mostly in in-vitro studies. The aim of the thesis therefore was: (1) to study peripheral metabolism of glucocorticoids during trinitrobenzensulfonic acid (TNBS) induced colitis in rat. (2) to study peripheral metabolism of glucocorticoids in biopsies from human ulcerative colitis (3) to examine peripheral metabolism of glucocorticoids during dextran sodium sulphate (DSS) induced colitis in rat and (4) to study peripheral metabolism of...
