Maternal smoking causes serious health danger for a mother but especially for a baby. Cigarette smoking produces complex steroidogenesis changes during the whole life of a woman. To study the influence of smoking on fetoplacental unit focusing on steroid hormons it was important first to concentrate on changes of the chosen steroids around the delivery. The first part of the thesis is dedicated to observe some chosen steroid hormons in peripartal period (37th week of the pregnancy, first stage of labor of mothers and mixed umbilical blood of their neonates) and to look for relations to the age of mother, the increase of the weight during the pregnancy, the type of the delivery and the sex of the baby. It was interesting to compare steroids in the relation to the type of the delivery: vaginal delivery versus planned caesarean section. Non-smoking women who delivered a boy spontaneously had significantly higher level of 17-OH-pregnenolone, progesterone, cortisol, corticosterone and significantly lower level of estradiol in comparison with non-smoking women who delivered a boy by a planned Caesarean section. In the maternal blood in the 37th week of the pregnancy there were found differences between steroids in accordance to the sex of the fetus but they were not found in the neonates' case. The age...

The Procollagen-Lysine, 2-Oxoglutarate 5-Dioxygenase (PLOD) family contains three members: PLOD1, PLOD2 and PLOD3. The PLOD family catalyze the lysyl hydroxylase (LH) which plays a crucial role in the synthesis of collagen. As one of the most important components in ECM, collagen plays a crucial role in normal tissues. Soft tissue sarcomas (STS) are malignant tumors with more than 100 subtypes which origin from mesenchymal tissue. Although the STS is a rare malignancy accounting for less than 1% of all adult tumors, it has been reported to be responsible for 20% of all cancer-related deaths in childhood and adolescence. In this study, the relation between PLOD family and STS was analyzed. The overexpression of PLOD family is associated with poor prognosis and the PLOD family seems to be a regulator in TME. The PLOD family could serve as strong novel biomarkers and may be used as a therapy target for personalized treatment in STS.

Despite various treatment attempts, the heterogenous group of soft tissue sarcomata (STS) with more than 100 subtypes still shows poor outcomes. Therefore, effective biomarkers for prognosis prediction and personalized treatment are of high importance. The Procollagen-Lysine, 2-Oxoglutarate 5-Dioxygenase (PLOD) gene family, which is related to multiple cancer entities, consists of three members which encode important enzymes for the formation of connective tissue. The relation to STS, however, has not yet been explored. In this study, data from The Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression (GTEx) databases were used to analyze the role of PLOD1–3 in STS. It was found that an overexpression of PLOD family members correlates with poor prognosis, which might be due to an increased infiltration of immune-related cells in the tumor microenvironment. In STS, the expression of PLOD genes could be a novel biomarker for prognosis and a personalized, more aggressive treatment in these patients.

Lower-grade glioma (LGG) is a group of tumors arising from the cells of the central nervous system. Although various therapy interventions are used, the prognosis remains different. Novel biomarkers are needed for the prognosis of disease and novel therapeutic strategies in LGG. The procollagen-lysine, 2-oxoglutarate 5-dioxygenase (PLOD) family contains three members and is related to multiple cancers, yet it was not investigated in LGG. Data from the Chinese Glioma Genome Atlas (CGGA) and The Cancer Genome Atlas (TCGA) cohorts were used to analyze the role of PLOD in LGG. As the PLOD family is involved in processes, such as tumor formation and cancer metastasis, we focused on its relationship to the tumor microenvironment (TME) in LGG. A high expression of the PLOD family relates to poor prognosis and high infiltration of immune cells within the TME. The expression level of the PLOD family might become a novel biomarker for prognosis and is a potential target for individual treatment decisions in LGG.

The thesis analyzes and interprets selected landscape motifs corresponding with biblical symbols in the first three collections of poetry of catholic author Václav Renč. The aim of this thesis is to give an opinion on my hypothesis that biblical symbol is a competent way of interpretation Bremond's pure poetry, and to evaluate the competence of Renč's poetry belonging to the concept of pure poetry. Also defining the limits of pure poetry through a comparison with the fourth Renč's collection which already shows significant changes in it's poetics. The theoretical part is focused on contemporary and modern literary-scientific views on Václav Renč's work, on the concept of poetry provided by Bremond, his reception in our backround and the role of the symbol in pure poetry. The thesis methodologically works with the symbol in connection with Zdeněk Mathauser's theory of a circle symbol that best corresponds with Bremond's understanding of poetry and is considered as the essential base of the theory of pure poetry. The practical part discusses the crucial landscape symbols (earth, flower and fruit, bush and tree) in single collections based on biblical interpretation and then describes their transformation in each of them.

Current status: Mental well-being in pregnancy is one of the most beautiful moments in a woman's life. It's such a miracle experience. There is a period of complete change with pregnancy. Both women and their partners are changing their living standards, changing their lifestyle, and changing their life position. A pregnant woman feels that nothing will be like before. A pregnant woman is very sensitive and also vulnerable. Purpose:The aim of the diploma thesis is to evaluate the psychosomatic situation of the pregnant woman and her influence on the prenatal and postnatal development of the child. Another goal is to determine the degree of mental (non) well-being during pregnancy and after delivery. Methods: Qualitative secondary analysis of data and documents and subsequent synthesis of the information obtained was used to achieve the objectives set. I used the data from the National Medical Library in Prague, the library of 2. LF UK and FN Motol in Prague, the library of National center of nursing and non-medical health providers in Brno and the Academic Library of the University of South Bohemia in České Budějovice. Also searched were the international internet database ScienceDirect, Ebscohost, PubMed. In the Scopus database, keyword search was unsuccessful. Results:The benefit of the diploma thesis is the degree of psychological well-being of pregnant women using the Freybergh scale on the basis of acquired data. Research method and research file: The diploma thesis uses a standardized evaluation method, using the Freybergh scale consisting of seventy closed questions. I will get the approval of the respondents and also Mr Freyberg, using a standardized scale. The annex is the approval of Professor Freyberghov, using the assessment scale in my diploma thesis. Respondents were ad-dressed from February 2017 until February 2018. A total of 30 pregnant women were approached by a written form, personal handover or social networking, of which fifteen were willing to engage in research. The research group was to consist of fifteen pregnant women, which is fulfilled. I responded to each respondent in third, sixth, ninth month pregnancies, and postpartum. When the respondents filled the same rating ranges from seventy questions both in the given months of pregnancy and postpartum, the respondents' task was to express the frequency of occurrence of feelings on a four-point scale from "never, at all", "rarely, exceptionally", "occasionally", "often" to "always, always, always". The nine respondents were first pregnant and six respondents had at least one pregnancy experience. The evaluation was performed using a qualitative method in the form of axial and selective coding of anchored claims using the Atlas.ti computer program. Conclusion: The paper deals with the degree extent of pregnancy psychosomatics of pregnant women using the Freybergh self-rating scale. The thesis is divided into two parts, namely the theoretical part and the practical part. The theoretical work focuses on the development of the fetus throughout pregnancy. It also focuses on prenatal psychology, prenatal history, and the most important part is prenatal communication. In the practical part is selected quantitative research focused on the psychological well-being of pregnant women using the Freybergh scale in selected months of pregnancy.

<p>Glavni cilj ove doktorske disertacije je određivanje hemijskog sastava, biolo&scaron;kih i funkcionalnih karakteristika novih proizvoda od zove. Dobijanje proizvoda na bazi zove zasniva se na primeni tradicionalnih i savremenih tehnolo&scaron;kih procesa proizvodnje. Iskori&scaron;ćenje prirodnog potencijala zove započeto je primenom tradicionalne i savremene (liofilizacija) tehnike su&scaron;enja. U cilju dobijanja visoko-vrednih ekstrakata ploda i cveta zove primenjene su tradicionalna (maceracija) i savremene (ultrazvučna i mikrotalasna) ekstrakcione tehnike sa dva ekstragensa (50% etanol i voda). Dobijanje matičnog soka od plodova zove podrazumevalo je primenu tradicionalnog načina ceđenja, dok je vino od plodova zove dobijeno po standardnom postupku proizvodnje vina. Vino je izloženo različitim temperaturnim tretmanima u različitom vremenskom periodu (60 &deg;C u toku 5 minuta, 60 &deg;C u toku 10 minuta, 70 &deg;C u toku 5 minuta i bez toplotnog tretmana) u cilju evaluacije biolo&scaron;ke aktivnosti dobijenog proizvoda. Etarsko ulje ploda i cveta zove je dobijeno hidrodestilacijom. Ispitivanje efikasnosti primenjenih tehnolo&scaron;kih postupaka su&scaron;enja i ekstrakcije je zasnovano na određivanju biolo&scaron;kih i funkcionalnih karakteristika dobijenih ekstrakata ploda i cveta zove. U ispitivanim ekstraktima ploda i cveta zove dominantne fenolne kiseline su hlorogenska i protokatehinska kiselina, a rutin i kvercetin-3-O-heksozid su dominantna flavonoidna jedinjenja. Biolo&scaron;ke i funkcionalne karakteristike su ispitane primenom različitih in vitro antioksidativnih, neuroprotektivnih, antitirozinaznih i antidijabetogenih testova. Primenom liofilizacije kao savremene tehnike su&scaron;enja i mikrotalasne ekstrakcije kao savremene ekstrakcione tehnike povećava se biopotencijal ispitivanih ekstrakata. Matični sok od plodova zove kao potencijalno novi funkcionalni proizvod je analiziran u cilju definisanja hemijskog, fitohemijskog i nutritivnog sastava, biolo&scaron;kog potencijala i senzorskih karakteristika. Ispitivanja dobijenog vina su bila usmerena na utvrđivanje optimalnih uslova za proizvodnju voćnog vina. Definisanjem hemijskog i fitohemijskog sastava i evaluacijom biopotencijala vina određen je optimalan temperaturni profil za dobijanje jednog od novih funkcionalnih proizvoda. Na osnovu utvrđenog hemijskog sastava etarsko ulje ploda i cveta zove se pokazalo kao potencijalno novi prirodni agens za održavanje svežine i produženja roka trajanja prehrambenih proizvoda. Zova je nesumnjivo samonikla biljna vrsta koja u budućnosti osnovano može biti polazna sirovina za kreiranje i dobijanje novih prehrmabenih proizvoda na domaćem i inostranom trži&scaron;tu.</p> / <p>The main goal of this doctoral dissertation is to determine the chemical composition, biological and functional characteristics of new elderberry products. Elderberry products were obtained via traditional and modern technological processes. The exploitation of the natural potential of the elderberry started with the application of traditional and modern (lyophilization) drying techniques. To obtain high-value extracts of fruits and flowers, traditional (maceration) and modern (ultrasonic and microwave) extraction techniques with two solvents (50% ethanol and water) were applied. Obtaining the juice from the elderberry fruits implied the application of the traditional cold pressing method, whereas wine from the elderberry fruits was obtained in accordance with the standard procedure of wine production. The wine was exposed to different temperature treatments in different periods (60&deg;C for 5 minutes, 60&deg;C for 10 minutes, 70&deg;C for 5 minutes and without heat treatment) to evaluate the biological activity of the product. The essential oil of the fruit and flower was obtained by hydrodistillation. The examination of the efficiency of the applied technological procedures of drying and extraction is based on observing the biological and functional characteristics of the obtained extracts of the said fruits and flowers. In the examined fruit and flower extracts, the dominant phenolic acids are chlorogenic and protocatechuic acid, while rutin and quercetin-3-O-hexoside are the dominant flavonoid compounds. Biological and functional characteristics were examined using various in vitro antioxidant, neuroprotective, antityrosinase, and antidiabetic tests. The application of lyophilization and microwave extraction (as modern drying and extraction techniques) increased the biopotential of the analyzed extracts. Elderberry juice, a potentially new functional product, was analyzed to define the chemical, phytochemical and nutritional composition, biological potential, and sensory characteristics. The wine was tested in order to determine the optimal conditions for the production of fruit wine. By defining the chemical and phytochemical composition and evaluating the biopotential of wine, the optimal temperature profile for obtaining one of the new functional products was determined. Based on the obtained chemical composition, it is determined that the essential oil of fruits and flowers is a potentially new natural agent for maintaining freshness and extending the shelf life of food products. Without a doubt, elderberry is a wild plant species that could be used in the future as the starting material for creating and obtaining new food products on the domestic and foreign markets.</p>
