Outcomes of take-home naloxone programme in Czechia after two years of operation
Lihtar, Štěpán ; Mravčík, Viktor (advisor) ; Janíková, Barbara (referee)
BACKGROUND: Opioid overdose represents significant public health burden in both the Czechia and the world in general. Although the prevalence in opioid use in our country is relatively low, it carries a disproportionate risk of health damage, including death from overdose. An effective intervention in the event of an opioid overdose is the administration of naloxone - an opioid antagonist that displaces the opioid from its receptors and interrupts the depression of the respiratory center. So-called take-home naloxone programs are based on the distribution of naloxone to lay people to administer naloxone when they witness an overdose. Take-home naloxone program was approved by the Czech Council of Government for the Coordination of Drug Policy in 2020, and its implementation began in April 2021. AIMS: The aim of this theses is to analyze the results of the take-home naloxone program in Czechia after two years of its operation. METHODS: The research part of this theses is based on a combination of two components - quantitative and qualitative. The data come from the Naloxone project reports and the Naloxone distribution project reports, which are filled by representatives of the programs involved in the project and then sent to the National Monitoring Center for Drugs and Addiction. The quantitative...

New insulin-like growth factor 1 (IGF-1) analogs for receptor studies and therapeutic applications
Lin, Jingjing ; Jiráček, Jiří (advisor) ; Hodek, Petr (referee) ; Lapčík, Oldřich (referee)
The insulin/IGF system is an evolutionary conserved network that includes three closely related peptide hormones (insulin, IGF-1 and IGF-2), three homologous tyrosine kinase receptors (IR-A, IR-B and IGF-1R), a distinct IGF-2 receptor (IGF-2R), and six IGF-binding proteins. While insulin signals mainly via IR, playing a key role in glucose homeostasis, IGFs mainly signal via IGF-1R to mediate normal human growth. A tight control of ligands and receptors expression is crucial for the proper functioning of the organism. Aberrant signaling by these receptors is manifested in many pathological conditions, including cancer, growth disorders, neurodegenerative diseases and diabetes. Hence, the insulin/IGF axis represents a promising therapeutic target. In view of the multiple unsuccessful clinical anticancer trials performed either with tyrosine kinase inhibitors or antibodies targeted against IGF-1R, the development of novel selective and receptor-specific insulin and IGF analogs with minimized side effects would be of interest. Our study began with the recombinant preparation of IGF-1 dimers in which IGF-1 monomers are interlinked between their C- and N-termini with Ser-Gly linkers (length of 8, 15 or 25 residues). The goal was to investigate whether the binding of two covalently linked IGF-1 molecules...

Screening of selected alkaloids of Fumariaceae and Amaryllidaceae families on Farnesoid X receptor and the G protein-coupled bile acid receptor 1
Hutníková, Miriama ; Pávek, Petr (advisor) ; Chlebek, Jakub (referee)
Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmacology & Toxicology Student: Miriama Hutníková Supervisor: Prof. PharmDr. Petr Pávek, PhD. Title of diploma thesis: Screening of selected alkaloids of Fumariaceae and Amaryllidaceae families on the farnesoid X receptor and the G protein coupled receptor 1 Farnesoid X receptor (FXR) and bile acid receptor associated with G protein 1 (TGR5) significantly affect metabolic processes in the human body. The role of FXR in neuronal apoptosis in Alzheimer's disease (AD) has also been discovered. The possible structural similarity of the small lipophilic molecules binding to these receptors and the alkaloids found in the plants Corydalis cava and Narcissus pseudonarcissus, as well as the richoften use of these plants in traditional medicine, represent a potential therapeutic intervention for these molecules. In our screening methods, we performed tests using a luciferase gene reporter assay to determine the ability of the alkaloids to interact with FXR and TGR5 in the HepG2 cell line. Many derivatives have shown a strong ability to antagonize FXR and TGR5 activated by obethicholic (OCA) or litocholic (LCA) acids in this assay. Some of the compounds also demonstrated the ability to potentiate the effects of OCA or LCA. Cytotoxicity...

The effect of agonist and antagonist disets on submaximal bench press
Zeman, Ondřej ; Šťastný, Petr (advisor) ; Petr, Miroslav (referee)
1 Abstract Title: The effect of agonist and antagonist superset on submaximal performance during BP Objectives: The aim of this work is to determine the differences in effect of different types of sets and order of individual exercises on submaximal performance in BP, with resistence of 4RM and 4-minute rest interval. Methods: In this work, a method of experimental research combined with a method of analysis was used. Method of a randomized experimental research was applied during the achal research with non-changing conditions. Later, the collected data were analysed and evaluated using the MBD method of analysing. Results: The results of this work are significant changes in numbers of performed sets of BP during KON, ANT and AGO schemes, with AGO having a negative effect of -38% of performance when compared with KON scheme with 100% probability. ANT, on the other hand, showed a positive effect of +20% when compared to KON scheme with 95% probability. The results of this work suggest that using AGO is a good method to increase submaximal performance in BP. Keywords: agonist, antagonist, volume, hypertrophy, individualization, physical intervention

Italo Svevo's Novels
ČECHOVÁ, Hana
The main subject of this bachelor thesis is the analysis of three novels written by Italo Svevo. First chapter presents briefly the author and the city of Terst which had an impact on his poetics. The following chapters analyses successively the novels Una vita, Senilita and La coscienza di Zeno. Especially emphasized are the typical protagonist called inetto and his changes within the framework of these novels. Mentioned are also the role of a woman, the contrast between inetto and the antagonist and some others, for Svevo typical motives. Separated chapter is dedicated to the so called literary silence of Italo Svevo.
