Full textIn the past years, several important advances have expanded our understanding of the pathways that lead to cell dysfunction and death in Parkinson’s disease (PD) and Huntington’s disease (HD). Both diseases are movement disorders characterized by the loss of a specific subset of neurons within the basal ganglia, dopaminergic neurons in the substantia nigra pars compacta (SNpc), in the case of PD, and medium spiny neurons in the striatum, in the case of HD,. Despite distinct clinical and pathological features, these two neurodegenerative disorders share critical underlying pathogenic mechanisms such as the presence of misfolded and/or aggregated proteins, oxidative stress and mitochondrial anomalies. Mitochondria are the prime energy source in most eukaryotic cells, but these highly dynamic organelles are also involved in a multitude of cellular events. Disruption of mitochondrial homeostasis and the subsequent mitochondrial dysfunction plays a key role in the pathophysiology of neurodegenerative diseases. Therefore, maintenance of mitochondrial integrity through different surveillance mechanisms is critical for neuronal survival. In this thesis I have studied in depth some mitochondrial quality control mechanisms in the context of PD and HD, in order to broaden the knowledge about the pathomechanisms leading to cell death. In the first chapter I have studied mitochondrial protein import in in vitro and in vivo models of PD. In vitro, complex I inhibition, a characteristic pathological hallmark in PD, impaired mitochondrial protein import. This was associated with OXPHOS protein downregulation, accumulation of aggregated proteins inside mitochondria and downregulation of mitochondrial chaperones. Therefore, we aimed to reestablish the mitochondrial protein import by overexpressing two key components of the system: translocase of the outer membrane 20 (TOM20) and translocase of the inner membrane 23 (TIM23). Overexpression of TOM20 and TIM23 in vitro restored protein import into mitochondria and ameliorated mitochondrial dysfunction and cell death. Complex I inhibition also impaired mitochondrial protein import and led to dopaminergic neurodegeneration in vivo. Overexpression of TIM23 partially rescued protein import into mitochondria and slightly protected dopaminergic neurons in the SNpc. On the contrary, TOM20 overexpression did not rescue protein import into mitochondria and exacerbated neurodegeneration in both SNpc and striatum. These results highlight mitochondrial protein import dysfunction and the distinct role of two of their components in the pathogenesis of PD and suggest the need for future studies to target other elements in the system. In the second chapter, I have studied the role of huntingtin in mitophagy and how the polyglutamine expansion present in mutant huntingtin can affect its function. For such, I worked with differentiated striatal ST-Q7 (as control) and ST-Q111 (as mutant) cells, expressing full length huntingtin. In these conditions, induced mitophagy was not mediated by Parkin recruitment into depolarized mitochondria. Mutant huntingtin impaired induced mitophagy by altering wildtype huntingtin scaffolding activity at different steps of mitophagy process: (i) ULK1 activation through its release from the mTORC1, (ii) Beclin1-Vps15 complex formation, (iii) interaction of the mitophagy adapters OPTN and NDP52 with huntingtin and (iv) with LC3. As a result, mitochondria from ST-Q111 cells exhibited increased damage and altered mitochondrial respiration. These results uncover impaired mitophagy as a potential pathological mechanism linked with HD. In conclusion, we have discovered new mitochondrial targets for PD and HD emphasizing the important role that mitochondrial quality control plays in neurodegeneration

Full textModellering van die verspreiding van siektes oor kontak-netwerke verskaf waardevolle inligting aan beleidmakers en epidemioloë wat besluit op maatreëls vir voorkoming teen die siekte. Hierdie proefskrif hou n metode voor wat gebruik word om siekteverspreidings-netwerke te simuleer en te analiseer. Dit word gedoen op netwerke met nodusse wat varieer tussen N = 100 en N = 10000. Netwerke waarin HIV versprei word gebruik. Penbeheer word in n oopluskonfigurasie op elke nodus toegepas binne n geslote terugvoerlus op netwerkvlak. Penbeheer se doel is om slegs sekere nodusse te beheer om dieselfde uitkomste vir die voorkoms van HIV tydens n epidemie te meet. Die doel is om die gemiddelde waarskynlikheid vir oordrag van die siekte tussen nodusse te beheer en sodoende, deur middel van die tegniek genaamd bond percolation , te bepaal hoe groot die finale epidemie gaan wees. Sodra die gemiddelde waarskynlikheid bekend is, kan nodus-, netwerk- en populasiemodelle saamgestel word. Twee selektiewe penbeheer-strategieë (proporsioneel, en NMPC) word met mekaar en met n derde willekeurige tegniek vergelyk. Die beheer van begrotings, gemeet in quality-adjusted life years (QALYs), word deur die NMPC strategie hanteer. Siektes binne kontaknetwerke kan dus beheer word met selektiewe penbeheer. Penbeheer-strategieë word ook vergelyk op grond van die dosisse wat hulle benodig, asook die akkuraatheid van die bestendigde-toestand resultate. Penbeheer van siekteverspreidings-netwerke is n werkbare metode om toekomstige en bestendigde-toestand uitkomste van mediese ingrepe op netwerke mee te analiseer.

L’objectiu d’aquesta tesi és avançar el nostre coneixement sobre els mecanismes de control involucrats en la producció de llenguatge en bilingües. He investigat aquest tema de dues maneres: Primer: he explorat les similituds entre el control bilingüe del llenguatge i el control executiu de domini general. Segon: he investigat l’especificitat dels mecanismes de control bilingüe dins del domini lingüístic. Per aquest supòsit, he avaluat les respostes conductuals de bilingües Català/Castellà afectats per la malaltia del Parkinson i controls bilingües (no malalts) en tasques de control de llenguatge bilingüe, control executiu i control de llenguatge quan una sola llengua hi està involucrada. He estudiat aquesta malaltia degenerativa perquè afecta zones del cervell involucrades tant en control executiu de domini general, com en control bilingüe del llenguatge. Els descobriments d’aquesta dissertació suggereixen que alguns dels mecanismes de control bilingüe del llenguatge són altament específics, i no estan involucrats en altres contextos de control lingüístic o no lingüístic. D’altra banda, altres mecanismes de control estan compartits a través de diferents dominis i estan implementats per mecanismes de control executiu.

Foot-and-mouth disease (FMD) is a highly infectious viral disease of cattle, pigs, sheep, goats, buffalo, and artiodactyl wildlife species. Foot-and-mouth disease virus is endemic and periodic devastating epidemics have occurred and caused heavy economic losses in Iraq for a long time. The first official cases of FMD were recorded in 1937, while the first record of a specific FMD serotype in Iraq was serotype A in 1952. Other serotypes have been reported since then; serotypes O, SAT-1 and Asia1 were recorded in 1957, 1962, and 1975, respectively. Veterinary Services in Iraq has been severely weakened over the past two decades, and its infrastructure has been devastated as a consequence of previous political conflicts, wars and international sanctions. The breakdown of Veterinary Services led to the disruption of disease control strategies, collapse of disease surveillance and monitoring, and weakening of response systems. The destruction of the Al-Dora FMD laboratories for diagnosis and vaccine production by the United Nation in 1996, and the restrictions placed on the importation of vaccines have strongly affected the FMD control program. A severe epidemic of FMD occurred in Iraq in 1998, affecting 2.5 million ruminants and causing heavy losses in newly born animals. It is estimated to have killed about 550,000 animals. The outbreak was due to the serotype O1 Middle East strain which has affected large and small ruminants. In 2009, Iraq was severely affected by new serotype A (subtype A Iran 05). The major efforts of Veterinary Services in Iraq have been directed towards control of FMD by vaccination strategies. Two types of vaccine have been used, trivalent vaccine (O, A 22, and Asia 1) for cattle and buffalo and monovalent vaccine (O Manisa) for sheep and goats. Vaccination has been implemented once yearly on a voluntary basis. Sometimes other limited control measures have accompanied vaccination, which include quarantine, movement control, focused vaccination, disinfection, and public awareness programs. The FMD control program in Iraq has been confronted by many challenges: deficits in FMD surveillance and emergency preparedness, limited diagnostic capabilities, difficulties in restricting animal movement, and lack and irregular supply of appropriate vaccines.

Full textPests and diseases are important factors to take into account in order to avoid losses in crop production. Nowadays, the search of new enviro-friendly compounds to induce defence mechanisms in plants to fight against plant diseases is a priority. Thus, the goal of this thesis has been to study the action mode of the enviro-friendly inducers of resistance copper-heptagluconate, 1-methyltryptophan (1-MT) and ammonium in tomato-P. syringae pathosystem. In general terms, Cu-heptagluconate induces phenolic compounds, 1-MT induces stomatal closure and affects apoplastic content and bacterial motility, and ammonium nutrition produces a primary metabolism reprogramming. Moreover, the study of changes at root level under nitrate and ammonium sources has been carried out, showing that the addition of nitrate or C compounds to ammonium treatment alleviates its mild toxicity.
