Ceramid, ein zentrales Signalmolekül des Sphingolipidstoffwechsels, ist neben der de novo Synthese über die enzymatische Spaltung von Sphingomyelin und Glucosylceramid zugänglich. Genetische Mutationen, die eine Fehlfaltung der verantwortlichen Enzyme saure Sphingomyelinase (aSMase) und Glucocerebrosidase (GCase) begünstigen, könnten somit zu einer Dysregulation des gesamten Sphingolipidstoffwechsels und den damit verbundenen Signaltransduktionsprozessen führen. Niedermolekulare Inhibitoren können in Zellstudien einen Einblick in diese Prozesse geben und den Defekt eines Enzyms simulieren oder eine etwaige Überaktivität derselben Enzyme verhindern. Für derartige Studien ist die Möglichkeit einer zeitaufgelösten Inhibition von Vorteil. Für diese Methode müssten photolabile Schutzgruppen in eine bereits bekannte Inhibitorstruktur integriert werden. Im Fall der aSMase würden sich hierfür myo-Inosit-bisphosphat-Derivate anbieten, die starke, kompetitive Inhibitoren des Enzyms darstellen. Auf dieser Grundlage werden in der vorliegenden Arbeit die Synthese sowie die in vitro und in cellulo Wirkung des ersten zellpermeablen, photoaktivierbaren Inhibitors für die aSMase präsentiert. Kompetitive Inhibitoren können ebenso als sogenannte pharmakologische Chaperone fungieren, welche Proteine durch Herabsetzung der freien Energie des jeweiligen Faltungszustandes stabilisieren. Dies ist besonders bei von Mutationen betroffenen lysosomalen Enzymen von Interesse, um diese vor einem proteasomalen Abbau zu bewahren und einen geregelten Transport in die Lysosomen zu gewährleisten. So wurden in der vorliegenden Arbeit verschiedene myo-Inositderivate als potenzielle pharmakologische Chaperone für die aSMase und GCase synthetisiert. Um eine Verdrängung der Verbindungen vom aktiven Zentrum des Enzyms durch das natürliche Substrat zu beschleunigen, wurde eine Orthoesterfunktion in die Seitenkette der Inhibitorstruktur integriert, die im sauren Milieu der Lysosomen gespalten werden kann. / Ceramide, a central signaling molecule in sphingolipid metabolism, is in addition to the novo synthesis accessible via the enzymatic cleavage of sphingomyelin and glucosylceramide. Genetic mutations that promote misfolding of the responsible enzymes acid sphingomyelinase (aSMase) and glucocerebrosidase (GCase) could thus lead to a dysregulation of the entire sphingolipid metabolism and the associated signal transduction processes. Small molecule inhibitors can provide insight into these processes in cell studies and simulate the defect of an enzyme or prevent eventual overactivity of the same enzyme. For such studies, the possibility of a time-resolved inhibition would be advantageous. For this method, photolabile protecting groups would have to be integrated into the structure of a known inhibitor. In the case of aSMase, myo-inositol-diphosphate derivatives, which represent strong, competitive inhibitors of the enzyme, would be suitable for this purpose. On this basis, the synthesis as well as the in vitro and in cellulo effects of the first cell-permeable photocaged inhibitor for acid sphingomyelinase are presented in this work. Competitive inhibitors can also act as so-called pharmacological chaperones, which stabilize proteins by reducing the free energy of the respective folding state. This is of particular interest in the case of lysosomal enzymes affected by mutations, in order to protect them from proteasomal degradation and to ensure regulated transport into the lysosomes. In the present work, various myo-inositol derivatives were synthesized as potential pharmacological chaperones for aSMase and GCase. To accelerate displacement of the compounds from the enzyme's active site by the natural substrate, an orthoester function was integrated into the side chain of the inhibitor structure, which can be cleaved in the acidic environment of the lysosome.

Glycosphingolipid (GSL) metabolism is a complex process involving proteins and enzymes at distinct locations within the cell. Mammalian GSLs are typically based on glucose or galactose, forming glucosylceramide (GlcCer) and galactosylceramide (GalCer). Most GSLs are derived from GlcCer, which is synthesized on the cytosolic leaflet of the Golgi, while all subsequent GSLs are synthesized on the lumenal side. We have utilized both pharamacological and genetic manipulation approaches to selectively regulate GSL metabolism and better understand its mechanistic details. We have developed analogues of GlcCer and GalCer by substituting the fatty acid moiety with an adamanatane frame. The resulting adamantylGSLs are more water-soluble than their natural counterparts. These analogues selectively interfere with GSL metabolism at particular points within the metabolic pathway. At 40 µM, adaGlcCer prevents synthesis of all GSLs downstream of GlcCer, while also elevating GlcCer levels, by inhibiting lactosylceramide (LacCer) synthase and glucocerebrosidase, respectively. AdaGalCer specifically reduces synthesis of globotriaosylceramide (Gb3) and downstream globo-series GSLs. AdaGalCer also increases Gaucher disease N370S glucocerebrosidase expression, lysosomal localization and activity. AdaGSLs, therefore, have potential as novel therapeutic agents in diseases characterized by GSL anomalies and as tools to study the effects of GSL modulation. Two predominant theories have been developed to explain how GlcCer accesses the Golgi lumen: one involving direct translocation from the cytosolic-to-lumenal leaflet of the Golgi by the ABC transporter P-glycoprotein (P-gp, ABCB1, MDR1), and the other involving retrograde transport of GlcCer by FAPP2 to the ER, followed by entry into the vesicular transport system for Golgi lumenal access. To examine the in vivo involvement of P-gp in GSL metabolism, we generated a knockout model by crossbreeding the Fabry disease mouse with the P-gp knockout mouse. HPLC analyses of tissue Gb3 levels revealed a tissue-specific reduction in MDR1/Fabry mice. TLC analyses, however, did not show such reduction. In addition, we performed a gene knockdown study using siRNA against P-gp and FAPP2. Results show these siRNA to have distinct effects on GSL levels that are cell-type specific. These results give rise to the prospect of unique therapeutic approaches by targeting P-gp or FAPP2 for synthesis inhibition of particular GSL pathways.

The main goal of the thesis entitled "The selected methods of social work with clients self-non sufficient in health care facilities" was to describe and to analyze methods used in activation of the elderly suffering from dementia. It draws a comparison of different settings and explores workers's attitude to the methods of activation. The text of the thesis was mapped out into five chapters. The first chapter was set into the context of old age and ageing. The second chapter is concerned with the issues of self-sufficiency and dependency of old age and other related issues. The topic of the third chapter is old age in relation with memory. It defines memory and memory disorders in the elderly suffering from dementia. The fourth chapter is crucial and gives an idea of non-pharmacological and other possible activities which are eligible for application in practice and are intended to reduce cognitive disorders of cognitive functions and behavior disorders. The theoretical part enters into research carried out in four facilities which care for clients with dementia. The research section is represented by a qualitative research where methods of a half structured interview and observation were opted for. The interviews were realized with eight practicing experts. The outcomes gathered from the...

Le récepteur mélanocortine de type 4 (MC4R) est un récepteur couplé aux protéines G impliqué dans la régulation de la prise alimentaire et de l’homéostasie énergétique. Quatre-vingt pour cent des mutants du MC4R reliés à l’obésité morbide précoce (OMP) sont retenus à l’intérieur de la cellule. Le système de contrôle de qualité (SCQ) est probablement responsable de cette rétention, par la reconnaissance d’une conformation inadéquate des mutants. Le rétablissement de l’expression à la surface cellulaire et de la fonctionnalité de ces mutants est donc d’intérêt thérapeutique. Dans cette optique, des composés lipophiles spécifiques pour le MC4R ont été sélectionnés sur la base de leur sélectivité. Nous avons démontré qu’ils agissent à titre de chaperone pharmacologique (CP) en rétablissant l’expression à la surface cellulaire et la fonctionnalité des récepteurs mutants S58C et R165W, et qu’ils favorisent leur N-glycosylation complexe (maturation). Le suivi par BRET du site d’action des CP du MC4R suggère une action en aval de l’interaction calnexine-MC4R. De manière générale, une CP peut avoir un effet différent selon le mutant traité en induisant des conformations distinctes du récepteur plus ou moins aptes à se dissocier du SCQ et à activer la voie de signalisation, et un mutant peut répondre différemment selon la CP utilisée par des différences d’affinité pour le ligand, la CP et les effecteurs. Une meilleure compréhension du mode d’action des CP pourrait aider au développement de nouvelles approches thérapeutiques non seulement pour l’OMP, mais aussi pour d’autres maladies conformationnelles causées par le mauvais repliement de protéines. / The MC4R is a G-protein coupled receptor involved in the central regulation of food intake and energy homeostasis. Eighty percent of childhood obesity-related MC4R mutants are retained intracellularly, probably via the quality control system acting on misfolded receptors. Thus, rescuing cell surface targeting and functionality of these mutant receptors could be of therapeutic value. Cell permeable MC4R selective ligands have been tested and were able to restore cell surface expression and signalling activity of S58C and R165W MC4R mutants. Those compounds, according to their mode of action, are described as pharmacological chaperones (PC). The MC4R-PCs also helps to rescue the glycosylation pattern (maturation) of the MC4R mutants. The site of action of MC4R-PCs of the MC4R mutants monitored by BRET suggests an action downstream of the calnexin-MC4R interaction, most likely at the level of the Golgi apparatus. Generally, a CP can have different effects according to the mutant by stabilizing distinct conformations of the receptor that are more or less able to exit the quality control system and to activate the signaling pathway, and a mutant can respond differently according to the CP used by its distinct affinity to the ligand, the CP itself and the effectors. A better understanding of PCs’ mode of action could help in the design of novel therapeutic approaches not only for early-onset morbid obesity (EOMO) but also for other conformational diseases resulting from protein misfolding.

Tesis por compendio / [ES] El aumento del envejecimiento de la población a nivel mundial y la limitada eficacia de los tratamientos disponibles para la demencia plantean la necesidad de desarrollar intervenciones dirigidas al envejecimiento y a las enfermedades neurodegenerativas. También se hace necesario promover cambios relacionados con la percepción negativa sobre la vejez en la sociedad. Ante estos planteamientos se está informando de los posibles beneficios terapéuticos de las intervenciones basadas en las artes, como la arteterapia, en la promoción de la salud, prevención de la demencia y manejo de la sintomatología asociada. Debido al interés de este tema nos propusimos evaluar los principales efectos de la arteterapia en el envejecimiento y enfermedades neurodegenerativas, analizar los posibles beneficios de esta terapia dirigida a personas mayores durante la pandemia y conocer los efectos del arte respuesta como activismo artístico para promover el cambio social en los estereotipos asociados al envejecimiento. Con el fin de alcanzar estos objetivos se plantearon 5 estudios que han dado lugar a los 5 artículos publicados en revistas de impacto que componen la tesis doctoral. El primer estudio incluye una revisión sistemática que analiza los beneficios de la arteterapia en personas con Enfermedad de Alzheimer (EA): los resultados informan de mejoras en bienestar, calidad de vida, estado anímico y depresión. El segundo artículo muestra un estudio de un caso de Parálisis Supranuclear Progresiva (un parkinsonismo atípico) evaluando posibles beneficios de la arteterapia en la sintomatología asociada a la enfermedad. Los resultados informan de mejoras significativas en expresión emocional, aspectos conductuales y relaciones sociales. El tercer trabajo analiza la relación entre EA y el duelo crónico basándose en un estudio de caso de EA, evaluando los efectos de la arteterapia en los síntomas cognitivos, somáticos y psicológicos. Se observó un impacto positivo en la expresión emocional, aspectos cognitivos (concentración, control, memoria), relaciones sociales y cambios en el sentido de identidad. El cuarto estudio describe una intervención de arteterapia en un grupo de mujeres de edad avanzada realizada durante las restricciones impuestas por la pandemia analizando las dificultades asociadas a este periodo y proponiendo su abordaje a través de la arteterapia. Los resultados sugieren mejoras en aspectos cognitivos (concentración, memoria y atención), expresión e identificación emocional, socialización y disminución de la ansiedad. El quinto estudio consta de dos proyectos relacionados (exposición virtual y talleres intergeneracionales) que tienen como denominador común el arte respuesta como activismo artístico, promoviendo la concienciación y el cambio social, y utilizando el arte respuesta para dar sentido y significado a las reflexiones relacionadas con el envejecimiento. Las experiencias incluidas en las 5 publicaciones contribuyen a generar avance del conocimiento acerca de las posibles aplicaciones de la arteterapia en el envejecimiento, enfermedades neurodegenerativas y prevención de la demencia. También se muestra su utilidad para contrarrestar la privación sensorial y social que conllevan las situaciones de crisis como las vividas durante la pandemia. Además, se han diseñado intervenciones basadas en el activismo artístico que pueden contribuir a desafiar estereotipos y superar actitudes negativas de la sociedad hacia la vejez. En futuros estudios sería de interés realizar intervenciones en muestras más amplias y con seguimiento longitudinal, así como el uso complementario de biomarcadores o técnicas de neuroimagen para evaluar los resultados de la intervención en la población de edad avanzada. Estas intervenciones arteterapéuticas pueden contribuir a crear experiencias participativas intergeneracionales basadas en las artes sobre la experiencia del envejecimiento / [CA] L'augment de l'envelliment de la població a nivell mundial i la limitada eficàcia dels tractaments disponibles per a la demència plantegen la necessitat de desenvolupar intervencions dirigides a l'envelliment i a les malalties neurodegeneratives. També es fa necessari promoure canvis relacionats amb la percepció negativa sobre la vellesa en la societat. Davant estos plantejaments s'està informant dels possibles beneficis terapèutics de les intervencions basades en les arts, com l'artteràpia, en la promoció de la salut, prevenció de la demència i maneig de la simptomatologia associada. A causa de l'interés d'este tema ens vam proposar avaluar els principals efectes de l'artteràpia en l'envelliment i malalties neurodegeneratives, analitzar els possibles beneficis d'esta teràpia dirigida a persones majors durant la pandèmia i conéixer els efectes de l'art resposta com a activisme artístic per a promoure el canvi social en els estereotips associats a l'envelliment. Amb la finalitat d'aconseguir estos objectius es van plantejar 5 estudis que han donat lloc als 5 articles publicats en revistes d'impacte que componen la tesi doctoral. El primer estudi inclou una revisió sistemàtica que analitza els beneficis de l'artteràpia en persones amb Malaltia d'Alzheimer: els resultats informen de millores en benestar, qualitat de vida, estat anímic i depressió. El segon article mostra un estudi de cas de Paràlisis Supranuclear Progressiva (un parkinsonisme atípic) avaluant possibles beneficis de l'artteràpia en la simptomatologia associada a la malaltia. Els resultats informen de millores significatives en expressió emocional, aspectes conductuals i relacions socials. El tercer treball analitza la relació entre Malaltia d'Alzheimer i el dol crònic basant-se en un estudi de un cas de Malaltia d'Alzheimer, avaluant els efectes de l'artteràpia en els símptomes cognitius, somàtics i psicològics. Es va observar un impacte positiu en l'expressió emocional, aspectes cognitius (concentració, control, memòria), relacions socials i canvis en el sentit d'identitat. El quart estudi descriu una intervenció d'artteràpia en un grup de dones d'edat avançada realitzada durant les restriccions imposades per la pandèmia analitzant les dificultats associades a este període i proposant el seu abordatge a través de l'artteràpia. Els resultats suggerixen millores en aspectes cognitius (concentració, memòria i atenció), expressió i identificació emocional, socialització i disminució de l'ansietat. El quint estudi consta de dos projectes relacionats (exposició virtual i tallers intergeneracionals) que tenen com a denominador comú l'art resposta com a activisme artístic, promovent la conscienciació i canvi social, i utilitzant l'art resposta per a donar sentit i significat a les reflexions relacionades amb l'envelliment. Les experiències incloses en les 5 publicacions contribuïxen a generar avanç del coneixement sobre les possibles aplicacions de l'artteràpia en l'envelliment, malalties neurodegeneratives i prevenció de la demència. També es mostra la seua utilitat per a contrarestar la privació sensorial i social que comporten les situacions de crisis com les viscudes durant la pandèmia. A més, s'han dissenyat intervencions basades en l'activisme artístic que poden contribuir a desafiar estereotips i superar actituds negatives de la societat cap a la vellesa. En futurs estudis seria d'interés realitzar intervencions en mostres més àmplies i amb seguiment longitudinal, així com l'ús complementari de biomarcadors o tècniques de neuroimatgeria per a avaluar els resultats de la intervenció en la població d'edat avançada. Estes intervencions artterapèutiques poden contribuir a crear experiències participatives intergeneracionals basades en les arts sobre l'experiència de l'envelliment / [EN] The increasing aging of the world's population and the limited effectiveness of available treatments for dementia increase the need to develop interventions that target aging and neurodegenerative diseases. There is also a need to promote changes in negative societal perceptions of old age. In light of these approaches, the potential therapeutic benefits of arts-based interventions, such as art therapy, in health promotion, dementia prevention and management of associated symptoms are being reported. Due to the interest of this topic, we proposed to evaluate the main effects of art therapy in ageing and neurodegenerative diseases, to analyze the possible benefits of this therapy for older people during the pandemic, and to know the effects of response art as artistic activism to promote social change in the stereotypes associated with ageing. In order to achieve these objectives, 5 studies were proposed, which gave rise to the 5 articles published in high impact journals that make up the thesis. The first study is a systematic review analyzing the benefits of art therapy in people with Alzheimer's disease: the results report improvements in well-being, quality of life, mood and depression. The second article presents a case study of a person living with Progressive Supranuclear Palsy (atypical parkinsonism), evaluating the potential benefits of art therapy on the symptomatology associated with the disease. The results report significant improvements in emotional expression, behavioral aspects and social relationships. The third paper analyses the relationship between Alzheimer's disease and chronic grief based on a case study of a woman diagnosed with Alzheimer's disease, evaluating the effects of art therapy on cognitive, somatic and psychological symptoms. Positive effects were observed on emotional expression, cognitive aspects (concentration, control, memory), social relationships and changes in sense of identity. The fourth study describes an art therapy intervention with a group of old women, carried out during the restrictions imposed by the pandemic, analyzing the difficulties associated with this period and proposing an approach through art therapy. The results suggest improvements in cognitive aspects (concentration, memory and attention), emotional expression and identification, socialization and reduction of anxiety. The fifth study consists of two related projects (virtual exhibition and intergenerational workshops) that share the common denominator of Response Art as artistic activism, promoting awareness and social change, and using Response Art to give sense and meaning to reflections related to aging. The experiences included in the 5 publications contribute to the advancement of knowledge about the possible applications of art therapy in ageing, neurodegenerative diseases and dementia prevention. They also demonstrate its usefulness in counteracting the sensory and social deprivation associated with crisis situations such as those experienced during the pandemic. In addition, interventions based on artistic activism have been developed that can help to challenge stereotypes and overcome negative societal attitudes towards old age. In future studies, it would be interesting to carry out interventions in larger samples and with longitudinal follow-up, as well as the complementary use of biomarkers or neuroimaging techniques to assess the results of the intervention with older people. These art-therapeutic interventions can contribute to the creation of art-based intergenerational participatory experiences of aging / Marco Martínez, P. (2024).

The desire to enhance and make ourselves better is not a new one and it has continued to intrigue throughout the ages. Individuals have continued to seek ways to improve and enhance their well-being for example through nutrition, physical exercise, education and so on. Crucial to this improvement of their well-being is improving their ability to remember. Hence, people interested in improving their well-being, are often interested in memory as well. The rationale being that memory is crucial to our well-being. The desire to improve one’s memory then is almost certainly as old as the desire to improve one’s well-being. Traditionally, people have used different means in an attempt to enhance their memories: for example in learning through storytelling, studying, and apprenticeship. In remembering through practices like mnemonics, repetition, singing, and drumming. In retaining, storing and consolidating memories through nutrition and stimulants like coffee to help keep awake; and by external aids like notepads and computers. In forgetting through rituals and rites. Recent scientific advances in biotechnology, nanotechnology, molecular biology, neuroscience, and information technologies, present a wide variety of technologies to enhance many different aspects of human functioning. Thus, some commentators have identified human enhancement as central and one of the most fascinating subject in bioethics in the last two decades. Within, this period, most of the commentators have addressed the Ethical, Social, Legal and Policy (ESLP) issues in human enhancements as a whole as opposed to specific enhancements. However, this is problematic and recently various commentators have found this to be deficient and called for a contextualized case-by-case analysis to human enhancements for example genetic enhancement, moral enhancement, and in my case memory enhancement (ME). The rationale being that the reasons for accepting/rejecting a particular enhancement vary depending on the enhancement itself. Given this enormous variation, moral and legal generalizations about all enhancement processes and technologies are unwise and they should instead be evaluated individually. Taking this as a point of departure, this research will focus specifically on making a case for ME and in doing so assessing the ESLP implications arising from ME. My analysis will draw on the already existing literature for and against enhancement, especially in part two of this thesis; but it will be novel in providing a much more in-depth analysis of ME. From this perspective, I will contribute to the ME debate through two reviews that address the question how we enhance the memory, and through four original papers discussed in part three of this thesis, where I examine and evaluate critically specific ESLP issues that arise with the use of ME. In the conclusion, I will amalgamate all my contribution to the ME debate and suggest the future direction for the ME debate.

The diploma thesis deals with problems of depression in older people. Mainly the work is focused on identifying and analyzing the role of nurses in screening for depression in older people in primary care, acute care, long-term care and home care. This thesis was focused on theoretical direction and was used the method of design and demonstration. In this thesis was set one main goals with five research questions. The main goal was to identify and analyze the role of nurses in screening for depression in the elderly. RQ 1: What is the role of the nurse in screening for depression in the elderly? RQ 2: What is the role of the nurse in the primary care in screening for depression in the elderly? RQ 3: What is the role of the nurse in screening for depression in hospitalized patients in acute care? RQ 4: What is the role of the nurse in screening for depression in seniors in long-term and home care? RQ 5: What rating scales and methods are used in screening for depression in the elderly? The thesis introduce the concept of depression. The following are specified the causes of and the important factors that affect depression in the elderly. It also deals the differences in the clinical symptomatology of depression in old age. It explains possibilities and various barriers in the diagnosis of depression. Another chapter introduces complete geriatric examination, diagnostic classification systems, possible screening methods and scales for detection of depression in the elderly population. It also deals methods of pharmacological and non-pharmacological treatment and its possible complications associated with older age. By reason of increased suicide rate caused by depressive disorder the issue of suicidal behavior in the elderly is introduced. The next chapter deals with the nursing process, which is used by nurses in practice. It consists of the evaluation of the patient's health condition, making nursing diagnosis, creating nursing plan and subsequent implementation and evaluation. The nursing process is also needy for providing quality care. The nursing process in the stage of nursing diagnosis, introduces possible nursing diagnosis for a patient suffering from depression, which are based on the latest classification. Finally is described the role of nurses in screening for depression in the elderly in different health facilities and their contribution to the timely evaluation of depression in the elderly. This chapter introduces the role of nurses, nursing screening and collaboration with a physician. The role of nurses in screening for depression in different medical facilities is based on the first phase of the nursing process of assessment. On the basis of objective and subjective information, the nurse will assess the overall health and mental condition of the patient. Primarily, it was investigated what is the role of the nurse in screening for depression. On the basis of content analysis and synthesis it was necessary to used and processed domestic and foreign literature. A number of relevant sources are the results of various studies and Meta-analyzes, mostly from abroad, but also from the Czech Republic. The thesis can serve as a basis for nurses. The result of this thesis is to create e-learning material available for students in the Faculty of Health and Social Sciences of South Bohemia in Ceske Budejovice in the tutorial called Moodle.
