The influence of roots on the chemical properties of the apoplast and the rhizosphere
Puldová, Kristýna ; Fendrych, Matyáš (advisor) ; Šámalová, Markéta (referee)
Chemical properties of the apoplast and rhizosphere are crucial for plant development and its overall well-being. Apoplast includes space outside the plasma membrane and its content, such as gas, water, and solutes. Changes in apoplast properties significantly influence various processes. One of them is cellular growth - the pH-dependent extension of cell walls. The rhizosphere is the soil environment near and under the influence of roots. It is characterised by abiotic factors like the availability of nutrients and toxic compounds. It is also a space with a high representation of microbiome communities. Plants can significantly influence the chemical properties of both apoplast and rhizosphere to improve their growth conditions. This thesis summarises the most important mechanisms of plants' roots that change these chemical properties, focusing on the model plant Arabidopsis thaliana. It shows how and where these mechanisms intersect and in which way they influence each other. Emphasis is placed on the process of growth regulation and mechanisms of increasing nutrient availability. Keywords: apoplast, rhizosphere, H+ ATPase, root growth, rhizodeposition, root exudates, nutrients, microbiome
The role of the minor patient in the decision-making process regarding the provided health care
Šebková, Šárka ; Dvořáková, Vladimíra (advisor) ; Neugebauer, Jan (referee)
The bachelor's thesis entitled "The role of the minor patient in the decision-making process about the provided health care" deals with the issue of the rights of child patients and their respect. The work tries to outline the issue of providing health care to minor patients, its pitfalls and possible solutions to related problems. The aim of the work was to map the knowledge of minor patients in the area of their rights in the provision of health care and to evaluate their respect by health workers. The theoretical part of the thesis provides a basic overview of legal sources that regulate the role of minor patients in the provision of health care. This part of the work further outlines selected topics of the given issue from the point of view of valid legislation and points out possible pitfalls in practice. The empirical part presents the results of own work and their comparison with the results of other researches. The research method was a questionnaire of our own construction, which was distributed in the outpatient clinic of a general practitioner for children and adolescents. In the study itself were included 92 duly completed questionnaires. The results of the questionnaire survey showed that 72.83% of respondents think that they are given the opportunity to participate in decisions about...
Syndromes associated with numerical aberrations of gonosomes
Sluková, Kristýna ; Mrňáková, Hana (advisor) ; Trková, Marie (referee)
Before the offspring is born, multiple flaws in the DNA, that strongly influence its future life, can occur. These may include differences in the structure of the Chromosomes or their overall quantity. Deviations from the standard genetic attributes of those Chromosomes will cause anatomic and physiological changes on the specimen. These changes act in a repetitive manner if certain conditions are met and because of multiple combinations of symptoms, genetic syndroms with similar manifestations have been categorized and named. As these abnormalities occur in early pre-natal stages od the offspring's development, there is no way of preventing them, avoiding them or completely curing them.
Functional movement disorders of the temporomandibular joint in women of working age
Nulíčková, Denisa ; Benešová, Lucie (advisor) ; Málková, Magdaléna (referee)
BACHELOR THESIS ABSTRACT Author: Denisa Nulíčková Supervisor: Mgr. Lucie Benešová Title: Functional movement disorders of the temporomandibular joint in women of working age Abstract: The bachelor thesis deals with functional disorders of the temporomandibular joint in women of working age. The thesis is a diagnostic work. The main aim is to evaluate the most common functional changes and general common features of patients with temporomandibular joint dysfunction by means of extended kinesiological analysis. The sub-objective is to map the quality of life and the presence of stress factors in the patients' lives. The second sub-objective is to elaborate the proposal and goals of the physiotherapy intervention. The theoretical part, in addition to short chapters describing the anatomy and biomechanics of the temporomandibular joint, deals with functional temporomandibular disorders. It provides a comprehensive overview of their causes, symptomatology and relationship to other body structures. It also summarizes the consequences of excessive psychological stress in the context of these disorders and describes conservative methods of treatment. The practical part of the thesis consists of 5 case studies, which include detailed initial examinations. The standard kinesiological analysis is enriched with...
Factorization of quaternion and dual quaternion polynomials
Molnár, Michal ; Šír, Zbyněk (advisor) ; Vršek, Jan (referee)
In this thesis we provide basic algorithms for factorization of polynomials over quater- nions and dual quaternions. In the case of quaternions, we translate the art of finding roots of given polynomial into factorization. In the case of dual quaternions, we analyse the case of motion polynomials. We show when it is possible to find a factorization of such polynomial into linear terms and give a workaround if it is not. All of this is supplied with geometric interpretations. More specifically, we use the factorizations to construct mechanical linkages. 1
Leaf physiological and optical properties in relation to the Phytophtora × alni infection of black alder (Alnus glutinosa)
Oramová, Viktorie ; Lhotáková, Zuzana (advisor) ; Tomášková, Ivana (referee)
A current problem is the infestation of the black alder (Alnus glutinosa) by the pathogen P. × alni, which causes the loss of alder stands and disrupts riparian ecosystems. The spread of the 'phytophthora disease' occurs through water, the host is infected through the root system and the pathogen attacks the conductive tissues. As a result of the disease, the tree gradually loses its root system, lesions appear on the trunk, defoliation occurs and the individual inevitably dies. The only solution to the situation is preventive measures to prevent further spread by careful removal of infected alder trees. The aim of this paper is to discuss the relationship between black alder and P. × alni in the context of the physiological changes that occur in the foliage of the infested individual. Leaf functional traits, chlorophyll fluorescence and optical properties of black alder exposed to P. × alni (inoculation into soil or confirmed occurrence of the pathogen in natural conditions) were measured using non-invasive methods. The results of the chamber experiments suggest that the mean values of the measured parameters do not change significantly in the initial stages of infection, but there is a widening of the variance of the values in infected individuals. We tested whether the genetic origin of the...
Helminth-host interactions on hormonal level
Lukesová, Hedvika ; Mikeš, Libor (advisor) ; Horák, Petr (referee)
Interactions between helminths and their hosts at the hormonal level result from their biochemical coevolution. Host hormones play an important role in the life of many helminths, and helminths are able to exploit them in some cases. For example, by expressing their own analogous hormone receptors that bind host hormones. Alternatively, by influencing the levels of host hormones, as certain hormonal environments may be (dis)advantageous for the helminths. This is the case, for example, of male mice infected with Taenia crassiceps, which undergo feminization as a result of infection. Some helminths can produce their own specific factors that influence host physiology, behaviour or appearance and may be analogs (orthologs) of host hormones. An example is the plerocercoid growth factor produced by Diphyllobothrium mansonoides, which behaves very much like a growth hormone in the host, although it differs in its primary structure. Some hormonal interactions can affect both helminth reproduction and the reproduction of their hosts. Examples of host-specific hormones that have been shown to be produced by helminths include, e.g., the ecdysteroid hormones - ecdysone and ecdysterone. A full understanding of the hormonal interactions between helminths and their hosts may lead us to find new treatments for...
Legal presumption of paternity determination vs. the material truth
Šimečková, Kateřina ; Salač, Josef (advisor) ; Zvára, Michael (referee)
Legal presumption of paternity determination vs. the material truth Abstract This work discusses the relationship between paternity determined by one of the legal presumptions of paternity determination, as defined by the Civil Code, and the material truth, or the possible contradiction between them, which the nature of the legal regulation allows. In the Czech Republic, the paternity determination is governed by a total of five legal presumptions, which are based on the probability of paternity determined by them - a first presumption testifying to the mother's husband ex lege, its conversion in favor of the second presumption in the case of divorcing marriage, a one-and-a-half presumption consisting of the father's consent to the mother's artificial insemination, a second presumption based on the parent's consent statement before the relevant public authority, and finally, a third presumption based on the fact of the intercourse between the father and the mother at a decisive time, when paternity is determined by a court decision based on the proposal of some of the concerned persons. However, it follows from the nature of the matter, that paternity determined in this way does not have to be in conformity with biological paternity. The legal presumptions can be a means of quick and effective resolving...
A platform for creating and sharing interactive educational materials based on data from knowledge graphs
Matějík, Jakub ; Nečaský, Martin (advisor) ; Stenchlák, Štěpán (referee)
In this thesis, we will explore the possibilities of Solid technology and the use of Solid for application implementation. This application will be used to create mind maps and social networking for teachers and students. In order to do this, we will analyze the features of Solid for designing a social network application and its features and suitable use cases. Based on this analysis and user requirements, we will design the architecture along with the operations to make them convenient for the user. Next, we will learn about the concepts in Linked Data and analyze knowledge bases for use in our application. The result is implementing a proof-of-concept application that allows the intuitive creation of mind maps and their sharing within classes. 1
