Contribution of antioxidant enzymes to toxicity assessment in fluvial biofilms
Per tal d’avaluar l’impacte de la contaminació en els ecosistemes aquàtics, aquesta tesi es centra en una aproximació multi-biomarcador en els biofilms. En complement dels biomarcadors clàssics, es va demostrar que les ...
Contribution of histone modifications to double-strand break repair and aging
El mantenimiento de la integridad del DNA es fundamental para evitar la aparición de mutaciones. Entre los diferentes tipos de daños en el DNA a los que la célula debe enfrentarse, destacan las roturas de la doble cadena ...
Contribution of hypoxia inducible factor, HIF1α, to vascular inflammation and remodeling in giant cell arteritis (GCA). Effects of GM-CSF receptor blockade on HIF1α stabilization
Giant Cell Arteritis (GCA) is an immune-mediated disease affecting large and medium sized arteries. Its pathophysiology is not fully understood and its present treatment relies on glucocorticoids, which have important ...
The contribution of lifelong learning ecologies in online higher education: graduate student learning across contexts
Les institucions d'ensenyament superior s'han hagut d'adaptar cada vegada més a la digitalització de l'educació, així com a una àmplia demografia d'estudiants que es tornen a incorporar a la formació acadèmica en diferents ...
Contribution of marine heterotrophic cultured bacteria to microbial diversity and mercury detoxification
Els oceans conten aproximadament un total de 10^29 cèl·lules microbianes. Els bacteris marins són responsables de la major part de la respiració que es produeix en l’oceà i són essencials en els cicles biogeoquímics de la ...
Contribution of neuroinflammation to the pathology of the Ndufs4 KO mouse model of Leigh syndrome
El síndrome de Leigh (SL) és una malaltia mitocondrial amb una prevalença estimada d'un cas per cada 40.000 naixements. Típicament, el SL s'acompanya d'un procés neurodegeneratiu agut i progressiu. Tal com es veu en altres ...
Contribution of perforant path synaptic markers and GSK-3 to cognitive impairment and Alzheimer´s disease
La frecuencia de la enfermedad de Alzheimer (EA) y otras demencias está aumentando en todo el mundo debido al progresivo envejecimiento de la población. A pesar de que hay marcardores patológicos específicos para determinadas ...
The Contribution of roots: the division of labor between grammar and the lexicon in meaning composition
This dissertation explores the division of labor between grammar and the lexicon from the viewpoint of event structural theories which take verb meanings to decompose into event templates and roots. Event templates ...
The contribution of the PDK1/Akt signaling pathway to Alzheimer disease analyzed by knock-in mutation
La Enfermedad de Alzheimer (EA) es la patología neurodegenerativa más común. El envejecimiento es el factor de riesgo no genético más relevante de la enfermedad, que va acompañado de cambios neurofisiológicos y anatómicos ...
Contribution of the subcortical auditory pathway to the perception and processing of sounds
The auditory scene that we face during our day life is highly complex. The human auditory system is able to allow us to maintain a conversation with another person whilst ignoring the surrounding sounds but, at the same ...
Contribution of unexplored genomic variations to neurodevelopmental disorders
Neurodevelopmental disorders are a group of conditions with impairments of the personal, social, academic or occupational behaviour. Autism spectrum disorder is a neurodevelopmental disorder with a high genetic component ...
Contribution to advanced hot wire wind sensing
The thermal anemometry is a method which allows to estimate wind magnitude be the mean of measuring heat transfer to the ambient in a forced convection process. For Earth's atmosphere condition, this method is typically ...
