Isolace, charakterizace a aplikace biomedicínsky významného polymeru P(3HB-co-4HB) / Isolation, characterization and application of biomedically important polymer P(3HB-co-4HB)Krupičková, Kristýna January 2020 (has links)
This diploma thesis deals with the isolation and characterization of copolymer P(3HB-co-4HB). The teoretical part was prepared as a literature search which describe polyhydroxyalkanoates in general, their structure, synthesis, degradation and isolation. Furthermore, copolymers containing 4HB units are mentioned in this thesis and there is also no mentioned of the biosynthesis and biodegradation of copolymer P(3HB-co-4HB). The first aim of this diploma thesis was to find out which solvent is the best for copolymer extraction and then characterize obtained copolymer P(3HB-co-4HB). The isolated copolymer was characterized by gas chromatography, SEC-MALS, thermal analysis and SEM. In the second part of the thesis, release of model biologically active substance from the PHA films was studied. Rhodamine 6G dye was selected for the simulation, which was used to stain the copolymer films and the P(3HB) films. It was observed that film prepared from P(3HB-co-4HB) copolymer released entrapped substance much faster than film made from P3HB homopolymer, and, in addition, the copolymer was substantially more susceptible to enzyme degradation.

Studium mechanismů regulace vybraných proteinkinas / Study of regulatory mechanisms of selected protein kinasesPetrvalská, Olívia January 2018 (has links)
Through binding interactions with more than 300 binding partners, 14-3-3 proteins regulate large amount of biologically relevant processes, such as apoptosis, cell cycle progression, signal transduction or metabolic pathways. The research discussed in this dissertation thesis was focussed on investigating the role of 14-3-3 proteins in the regulation of two selected protein kinases ASK1 and CaMKK2. The main goal was to elucidate the mechanisms by which phosphorylation and 14-3-3 binding regulate functions of these protein kinases using various biochemical and biophysical methods, such as site-directed mutagenesis, enzyme activity measurements, analytical ultracentrifugation, small-angle X-ray scattering, chemical crosslinking, nuclear magnetic resonance and fluorescence spectroscopy. A structural model of the complex between the catalytic domain of protein kinase ASK1 with 14-3-3ζ, which was calculated using the small-angle X-ray scattering and chemical crosslinking data, suggested that this complex is conformationally heterogeneous in solution. This structural model together with data from time-resolved fluorescence and nuclear magnetic resonance suggested that the 14-3-3ζ protein interacts with the catalytic domain of ASK1 in the close vicinity of its active site, thus indicating that the complex...
