EI spectra interpretation
Polášek, Miroslav
2023 - Czech
Introduction to the interpretation of mass spectra. Basic mechanisms of fragmentation reactions in electron ionization. An intensive exercise on selected examples of mass spectra of electron ionization of different classes of organic compounds, which will be carried out in the spirit of the elementary didactic principle of progression from simple to complex with maximum emphasis on the independent work of the participants.\n\n Úvod do problematiky interpretace hmotnostních spekter. Základní mechanizmy fragmentačních reakcí při elektronové ionizaci. Intenzivní cvičení na vybraných příkladech hmotnostních spekter elektronové ionizace různých tříd organických sloučenin, které bude probíhat v duchu elementární didaktické zásady postupu od jednoduchého ke složitějšímu s maximálním důrazem na samostatnou práci účastníků.

Hejzlar, Josef; Porcal, Petr; Kopáček, Jiří; Jarošík, Jiří; Paule-Mercado, Ma
2023 - Czech
Long-term and seasonal changes in dissolved organic carbon (DOC) concentration and their causes in the years 1969–2021 were evaluated for the main tributary to the Římov water supply reservoir. Pro hlavní přítok do vodárenské nádrže Římov byly vyhodnoceny dlouhodobé a sezónní změny koncentrace rozpuštěného organického uhlíku (DOC) a jejich příčiny v letech 1969–2021.

Electrochemical Techniques in Monitoring of Nervous System Drugs
Choińska-Mlynarczyk, Marta; Hrdlička, Vojtěch; Skopalová, J.; Šelešovská, R.; Kolivoška, Viliam; Navrátil, Tomáš
2022 - English
Drugs of the nervous system (ATC group N) belong generally to the most commonly (mis)used substances worldwide. Their determination and monitoring of these drugs and their metabolites in various body fluids or environmental matrices represent a challenge for analytical chemists. Our research is focused on the application of electrochemical methods in the monitoring of the most frequently prescribed and the newly introduced nervous system drugs of precisely specified structures and/or of defined properties. For toxicological and pharmacokinetic reasons, emphasis has been placed on investigating the reaction mechanisms of their metabolite formation. New or alternative to commonly used electroanalytical methods applicable for monitoring and characterization of target compounds in their pure state, in body fluids, wastewaters, and other environmental matrices, has been developed. To improve the chemometric parameters and sensing characteristics, attention was paid to the construction of new electrochemical sensors, detectors (e.g. screen-printed, 3D printed), or cells, based on (modified/unmodified) traditional or nontraditional materials, preferably usable at the point-of-care.

Proteomics for beginners
Hubálek, Martin; Vrbacký, M.; Křenková, Alena
2022 - Czech
Proteomic tutorial for the beginners will summarise and present current methods to analyse and evaluate proteomic samples. The tutorial will be divided into two parts. The first part will focus on data accquisition process and interpretation of spectra. The second part will focus on protein quantification. Náplní kurzu bude úvod do proteomiky s cílem ukázat současné metody a nástroje použitelné k akvizici a vyhodnocení proteomických dat. Ve dvou na sebe navazujících částech kurzu budeme\nklást důraz na interpretaci proteomických spekter, pochopení principů identifikace peptidů a proteinů a kvantifikační postupy. Na praktických příkladech vysvětlíme De-novo sekvenaci peptidů a použití volně dostupných programů MaxQuant a Perseus na identifikaci, kvantifikaci a vizualizaci dat.
