Methodology development of the olfactory perception of children with visual and multiple disabilities
Pařízková, Linda ; Šumníková, Pavlína (advisor) ; Květoňová, Lea (referee)
This thesis deals with importance of olfactory perception and possibilities of its development between the children with visual and multiple disabilities. It provides basic information about anatomy and physiology of olfaction, about processing of olfactory stimuli and about the importance of smell for children with visual and multiple disabilities. The main attention is focused on possibilities of olfactory perception development in the Czech Republic, which is presented by a comprehensive summary of the products available on the Czech market. It also deals with the development of the olfactory perception at the School of Jaroslav Ježek.
Association between human body odour and health status
Schwambergová, Dagmar ; Havlíček, Jan (advisor) ; Vinkler, Michal (referee)
The subject of this thesis is to evaluate a link between changes in body odor and health status in humans. The main aim was to create a theoretical overview of the available studies concerning humans, which are compared with studies conducted on mammals. Alteration of body odor due to the ongoing disease may negatively influence not only the odor attractiveness of a potential partner, but also may cause changes in behavioral response to a chemical stimulus for other members of the species. One may assume formation of perceptual adaptations exhibiting sensitivity to markers of health status in both sexes. Recognition of ill individuals may be crucial during social interactions, to prevent transmission of pathogens, but in mate choice the health status may also serve as an important indicator of resistance to infection, which can affect the viability of the offsprings. The main contribution of this thesis is to summarize the knowledge and insights into the area related to changes in body odor, depending on the health status. Keywords body odor, health, sexual selection, attractiveness, olfactory perception
Sexual dimorphism in the mouse olfactory system
Kuntová, Barbora ; Stopka, Pavel (advisor) ; Havlíček, Jan (referee) ; Žídek, Lukáš (referee)
Sexually dimorphic behaviour of the house mouse (Mus musculus musculus) relies on various physical and chemical cues, however, chemical signals are the most essential cues for individual recognition and in causing various priming effects on reproductive behaviour of the receiver. House mice belong to macrosmatic mammals, and thus, their sense of smell is highly developed and is able to recognize a wide spectrum of ligands from other individuals and from their surrounding environment. Volatile signals belong to organic compounds that are produced by most tissues, and may have harmfull effects on cells, and thus they are transported out of the body with lipocalin transporters where some of them may function as signals. These volatile signals are able to stimulate chemosensory neuronal receptors, and thus, yield particular responses in neural circuits. The ligand sensing has a differential effect upon males and females, however, it has not been shown yet in wild mice whether these differences are also caused by the variation in receptors and neural processing, or rather by differential expression of signals typical for each sex. The aim of this thesis was to perform comparative analysis of orofacial mucosal tissues to determine the specificity of expression of particular lipocalins. For the first time...
Evolution of olfactory receptors
Klempt, Petr ; Stopka, Pavel (advisor) ; Vinkler, Michal (referee)
This bachelor thesis deals with the largest gene family of mammals which encode olfactory receptors. Olfactory receptors fall in rhodopsin-like GPCRs subfamily, approximately 600 - 800 millions of years old. At least from this time, olfactory receptors play, as a part of one of the oldest senses (smell), fundamental role in detection of chemical cues from water or air. This work summarizes large repertoire of olfactory receptors and its changes during the evolution of important animal taxons with emphasis on number and fraction of functional and nonfunctional olfactory receptor genes. Those values are part of criteria used for olfactory ability of animals. Olfactory receptors are typically placed on surface of sensory neuron placed in olfactory epithelium, where they bind various odorants and triggers signal cascade which leads to neuron's membrane depolarization. Therefore, about one half of this work summarizes knowledge of olfactory receptor's molecular biology like their structure, main parts of signal cascade (Gαolf, ACIII, CNG channel, Ca2+ dependent Cl- channel) just as parts needed for steady-state establishment. Expression of olfactory receptors detected in amount of non-olfactory tissues (mussels, sperm, brain etc.), indicate possibly important biomedical roles of this receptors.
Role of body odour in partner relationship
Černý, David ; Kuncová, Lucie (advisor) ; Martinec Nováková, Lenka (referee)
Body odor is a good guide in mate choice, because it contains information such as the kinship, emotional state, or health condition of an individual, a person is able to perceive this information to a certain extent. The individual factors that affect the body odor will subsequently influence the preferences for the body odor as well. Those preferences are applied especially when seeking for a partner and at the beginning of the relationship. At the same time, however, it turns out that body odor affects even the process of partnership and the end of it. In the context of relationships and olfactory communication in humans, especially in the context of sexual life, the effect of pheromones is often discussed, which is the subject of the last chapter. The aim of the work is to gather and critically evaluate existing studies dealing with the role of body odor in the partnership and to suggest possible directions for further research. Keywords: smell, pheromones, partner preferences, mate choice
Somatic work: How people relate to the olfactory experience with the example of foreigners in the CR.
Zídková, Kateřina ; Spalová, Barbora (advisor) ; Tesárek, Jan (referee)
This thesis is dealing with the sense of smell and how do we relate to it in our social lives. I was looking into the mechanics of somatic work. It is a term defined by Vannini and Waskul (2008) as a process whereby a somatic perception undergoes a reflexive interpretation. Somatic perception isn't something that just happens, it is actually a process which yield to socialization. On the basis of 8 qualitative interviews and 5 consequential smell diaries using the hermeneutic analysis I identified, how and in which situations do foreigners in the Czech Republic work with their sense of smell and olfactory experience. It is mostly in situations connected with food, places, nature and people. Each of these situations I examine in a separated chapter. Somatic work is being done in compliance with social norms. Within these social norms rules for handling odors are negotiated. So, I also looked into how these social norms function in connection with smells. I also described, how odors relate to memory and what meanings do people connect with it.
Creating snoezelen room for pupils with severe mental and combined disabilities
Hůrková, Lucie ; Volemanová, Marja Annemiek (advisor) ; Šumníková, Pavlína (referee)
The thesis deals with the creation of Snoezelen room, its characteristics and properties. He is more closely involved with the creation of snoezelen for pupils with mental and combined disabilities who are trained in special primary schools. The work describes the target group, defines the snoezelen method and describes its origin and development in our country and abroad. The main goal of the thesis is to explain to the reader how the rooms are created and what it is necessary to know before deciding to launch the snoezelen room. This information was used mainly by special teachers who operate snoezelena in facilities where they work in schools. The thesis also touches on the topic of education at special schools, methods of working with these pupils and describes types of expressive therapies, therapies, basal stimulation and sensory stimulation. The thesis also reflects the Snoezelen-MSE qualification course in theory and practice, which was the main source. The output of the thesis is a proposed room model, description of equipment and activities that are suitable for working with disadvantaged pupils.
Relationship between reactivity of immune system and quality of human body odour
Schwambergová, Dagmar ; Havlíček, Jan (advisor) ; Vinkler, Michal (referee)
It was previously proposed that expression of secondary sexual characteristics may provide cues to individual's immunocompetence. Body odour could partly serve as one of such characteristics, which provides crucial information about potentional partner even in humans. The main aim of the diploma thesis was to test a relationship between body odour quality and reactivity of immune system. In empirical part of the study we collected body odour samples from 21 men aged between 18-40 years before and two weeks after the vaccination against hepatitis A and B (Twinrix) and meningococcus (Menveo). The participant's blood samples were obtained three times to determine levels of IgG and IgM antibodies (markers of reactivity of immune system), testosterone, cortisol and CRP levels. In the second part of the study, a panel of 88 female raters aged 18-40 assessed body odour samples for their attractiveness, intensity and healthiness. In contrast to our expectations, we found no significant association between levels of antibodies induced by vaccination and perceived body odour attractiveness and health. Simultaneously, there were no significant changes in body odour ratings, neither in levels of testosterone and cortisol ratings, before and after the vaccination. However, we found a negative association...
