Development and optimization of chromatographic methods suitable for clinical application
Jenčo, Jaroslav ; Solich, Petr (advisor) ; Hroboňová, Katarína (referee) ; Šatínský, Dalibor (referee)
Charles University, Faculty of Pharmacy in Hradec Králové Department: Department of Analytical Chemistry Candidate: Mgr. Jaroslav Jenčo Supervisor: prof. RNDr. Petr Solich, CSc. Consultant: doc. RNDr. Lenka Kujovská Krčmová, Ph.D. Title of dissertation thesis: Development and optimization of chromatographic methods suitable for clinical application The presented dissertation thesis is divided into several parts, copying the workplaces, which I gradually worked on. The unifying element is the development and optimization of methods for the preparation of samples of biologically active substances and their subsequent analysis using separation methods. The theoretical part characterizes the target substances, from a biochemical, physicochemical, and analytical point of view. It describes the basic characteristics of extraction procedures and presents an overview of the methods used to determine the substances described in the thesis. In the first, main experimental part, of the dissertation thesis the development, optimization, and validation of an analytical method for chromatographic analysis of vitamin B1, its biologically active forms and the active form of vitamin B6 in blood is described. It illustrates the selection of sample preparation techniques, the optimization of the target methodology...
Interactions of reduced and oxidized glutathione with copper, iron and zinc
Salanciová, Ingrid ; Karlíčková, Jana (advisor) ; Jenčo, Jaroslav (referee)
Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical Botany Candidate: Ingrid Salanciová Supervisor: PharmDr. Jana Karlíčková, Ph.D. Title of Thesis: Interactions of reduced and oxidized glutathione with copper, iron and zinc Copper (Cu), iron (Fe) and zinc (Zn) are important trace elements that are necessary for proper function of the body. Excess but also the lack of these metals may lead to pathological conditions. Glutathione is the main antioxidant in the human body so it is expected to protect the organism against concequences of metal excess. Glutathione occurs in the reduced (GSH) and oxidized state as glutathione disulfide (GSSG) in the organism, both states forming an important redox system. On the other hand, glutathione can reduce these metals so that could participate in the formation of free radicals (metal based Fenton reaction). In this diploma thesis, was tested the ability of reduced and oxidized glutathione to interact with Fe, Cu and Zn in various (patho) physiological pH conditions was tested by using in vitro spectrophotometric competitive methods. Interactions include not only the chelation of Cu, Fe and Zn ions, but also their reductive activity toward Cu2+ and Fe3+ cations. Hematoxylin, bathocuproinedisulfonic acid disodium salt, ferrozine...
Determination of biochemical parameters and their diagnostic and prognostic value in sepsis
Jenčo, Jaroslav ; Dršata, Jaroslav (advisor) ; Boušová, Iva (referee)
Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Biochemical Sciences Candidate: Bc. Jaroslav Jenčo Supervisor: prof. MUDr. Jaroslav Dršata, CSc. Consultant: Ing. Jana Netriová, PhD. Title of diploma thesis: Determination of biochemical parameters and their diagnostic and prognostic value in sepsis Sepsis is a relatively common complication that may be signed by the increased mortality of patients. It affects all ages, regardless of gender. Occurrence is more frequent in polymorbid and immunosuppressed patients. The most effective method to prevent the development of septic complications is quick and accurate diagnosis. In the period from 1.6.2012 to 01.4.2014, we observed 697 patients hospitalized due to the development of septic complications and we analyzed statistically tracked markers: presepsin, procalcitonin, C - reactive protein, interleukin - 6, lactate, D - dimer, fibrinogen and quantity of leukocytes to determine their predictive and diagnostic value. Largest correlation was observed between comparison of presepsin with procalcitonin and presepsin with C - reactive protein, which reflected rapidly changing status of patients. Moderate correlation was observed in lactate, interleukin - 6, D - dimer concentration and leukocyte count. Between the development...
