Využití HPLC v chirálních separacích V. / The use of HPLC in the field of chiral separations V.Burda, Jakub January 2020 (has links)
Charles University Faculty of Pharmacy in Hradec Králové Department: Department of Pharmaceutical Chemistry and Pharmaceutical Analysis Candidate: Jakub Burda Supervisor: doc. PharmDr. Radim Kučera, Ph.D. Title of Thesis: The employment of HPLC in the field of chiral separations V. Continuously growing requirements of regulatory authorities for the quality and safety of medicines put a high pressure on manufacturers. Last decades are marked by optically pure drugs, whose developement goes hand in hand with developement of chiral syntheses and separations. The most used method in the field of separations are direct separations using chiral stationary phases. The most often used carrier for these stationary phases is silica, which may contain metal impurities on its surface, negatively impacting separation process. The focus of this thesis was testing of influuence of chromatographic conditions on chiral and achiral interactions of seven selected analytes with stationary phase. Column with native β-cyclodextrin as chiral selector was used for the testing. 1

Analýza lékových interakcí u pacientů přijatých k hospitalizaci (I.) / Analysis of drug-drug interactions in patients admitted to hospital (I.)Kukrálová, Kateřina January 2021 (has links)
Candidate: Kateřina Kukrálová1 Supervisor: prof. RNDr. Jiří Vlček, CSc.1 Consultant: PharmDr. Zuzana Očovská1 1 Department Social and Clinical Pharmacy, Faculty of Pharmacy in Hradec Králové, Charles University Title of the master thesis: The analysis of drug-drug interactions in patients admitted to hospital (I.) The presence of potential drug-drug interactions (DDIs) is common in daily practice and only a small proportion of potential DDIs results in hospitalization of the patients. Nevertheless, DDIs represent a significant cause of hospital admissions. This study aims to identify DDIs in the medication history of the patients admitted to University Hospital Hradec Králové via the emergency department in August-November 2018. The objectives of this study are a) to determine the prevalence of potential DDIs; b) to categorize identified potential DDIs with respect to their mechanism, severity, risk rating, level of documentation and potential outcomes and c) to determine the prevalence of manifest DDIs. This study has a cross-sectional design. The following data were obtained retrospectively from electronic medical records: demographic data, medication history, past medical history, laboratory and clinical findings, and information about hospital admission. The identification of potential DDI was...

Interaktivní narativ jako prostředek analýzy elektronických videoher / Interactive Narrative as a Mean of Analysis in Electronic VideogamesCsémy, Miklós January 2011 (has links)
1 Abstract: This thesis is focused on researching options of analysis in electronic videogames, using the concept of interactive narrative. In analysis, the electronic videogame is always encountered as an individual piece of work. The thesis describes the model of interaction between the player and the electronic videogame based on existing psychological literature. The interactive narrative is used to describe the structure of the electronic videogame. The analysis happens on two levels. The first level is based on the game code, which is seen as the sum of options which may be actualized in the process of interaction. The thesis refers to this as the predisposed narrative. The second level lies in the moment of interaction itself, where the result of player's activity leads to representation of some of the aforementioned options and disregard of others. This concept helps solve the question of narrativity in electronic videogames by differentiating the fabula, which is the work of the original game maker from the interactive narrative, which encompasses both the predisposed narrative and its actualization.

Hyperjemné interakce v multiferoikách obsahujících železo / Hyperfine interactions in multiferroics containing ironKmječ, Tomáš January 2021 (has links)
Multiferroic materials, in which spontaneous orderings (especially magnetic and electrical, in some cases elastic) jointly exist and may mutually interact, are currently in the center of attention in many fields of research due to their high application potential. They are already used in many applications, as in various sensors, microwave filters or electro / magneto- mechanical manipulators and actuators. Nevertheless, many features of microstructure and moment arrangements are not yet fully explained and understood. The presented work is mostly experimental and focuses on the investigation of several promising multiferroic materials: Pb1 − xBax(Fe0.5Nb0.5)O3 (x = 0 - 1) and Pb(Fe0.5Sb0.5)O3 with a perovskite structure and labeled as multiferroics of the I. type according to the Khomsky classification, BaYFeO4, which belongs to the multiferroics of the II. Khomsky class, and LiFePO4, which is a potentially multiferroic substance containing Fe2+ and are used in electric accumulators at present. Mössbauer spectroscopy of the 57 Fe isotope was used as a key experimental method, which can provide new information about the local arrangement in the vicinity of resonantly absorbing nuclei in the investigated substances. Data evaluation and interpretation would not be possible without the using results...

Srovnání indukce a regulace autofagocytózy v proliferujících a senescentních nádorových buňkách / Srovnání indukce a regulace autofagocytózy v proliferujících a senescentních nádorových buňkáchPešina, František January 2014 (has links)
Autophagy, senescence and apoptosis are tightly linked processes which together determine the fate of cells in response to various stresses. There is ample evidence supporting the notion that senescent cells are highly dependent on autophagy and this process is here much more intensive than in nonsenescent cells. Autophagy may to some extent compensate increased energetic and metabolic demands of senescent cells and also helps with removal of toxic products such as oxidized proteins, protein aggregates and damaged organelles resulting from an overloaded metabolism of some senescent cells. In addition, some studies reported the need of autophagy for the adoption of senescent phenotype. However, there are also studies with seemingly contradictory results claiming that increased autophagy prevents or delays cellular senescence. Relationship of autophagy to apoptosis is similarly ambivalent. Whereas intact autophagy is necessary for the cell, while slightly increased autophagy still has a rather positive impact, excessive autophagy may lead to degradation of critical components necessary for cell function and survival and can trigger one of the modes of programmed cell death. In the first part of this work, we focused on the analysis of autophagic response in senescent and proliferating pancreatic...

Mezimolekulové interakce v proteinech / Intermolecular interactions in proteinsKysilka, Jiří January 2013 (has links)
Intermolecular Interactions in Proteins - Abstract Mgr. Jiří Kysilka Non-covalent interactions are responsible for the protein folding and the molecular recognition during the protein interaction with other molecules, including various ligands, other proteins and solvent molecules. In order to understand these processes, exhibited by protein molecules, a proper description of non-covalent interactions is needful. Most methods that are computationally available for the systems of biological interest have difficulties handling with the dispersion term. In this thesis, a density functional theory / coupled clusters (DFT/CC) correction scheme is utilized for a set of small molecules, interacting with a graphitic surface. The results serve as a benchmark for the interaction of the functional groups of proteins with hydrophobic environment. In the following part of this thesis, the role of non-covalent interactions in proteins was studied for the processes of protein-protein interaction and protein hydration. Interaction interfaces has been localized in a set of 69 protein dimers and their composition has been characterized. Interfaces has been shown to prefer branched-chain hydrophobic amino acids (Ile, Leu, Val), aromatic amino acids (Phe, Tyr) and exclude the charged amino acids except of Arg. It was...

Aplikace metod počítačové fyziky při studiu interakce plazmatu s pevnými látkami / Application of methods of computational physics for the study of plasma-solid interactionHromádka, Jakub January 2013 (has links)
Low-temperature plasma and its interaction with immersed solids is studied in this work. The research of the physical processes on this interface is performed by two-dimensional particle computer model. The model uses molecular dynamic method. Mutual forces between particles are computed by Particle- in-Cell method. The main application of the model is in the area of the probe diagnostic of plasma. Simple problems are compared with theory and two dimensional effects are discused. Contribution of particle modeling to plasma research is showed on the problem of interaction of sheaths around cylidrical probes. We deal with question whether we are able to get some information about unevennesses at the surface of solid immersed in plasma by measuring probe characteristics in its surroundings. We also studied the influence of plasma electronegativity on the parameters of sheaths around cylidrical probes. Powered by TCPDF (www.tcpdf.org)
