Els oòcits de vertebrats es troben aturats a la profase I de la primera meiosi (PI). Durant el procés anomenat oogènesi, els oòctits sintetitzen i emmagatzemen grans quantitats d'ARN missatgers(ARNm)que els seran necessaris ...
Gene regulation is a complex biological process that requires the coordinated interaction of different molecules. The integrity of the underlying mechanisms ensures the correct expression of genes that maintain cell ...
Rheumatoid arthritis, psoriasis, psoriatic arthritis, systemic lupus erythematosus, Crohn’s disease and ulcerative colitis are six of the most prevalent immune-mediated inflammatory diseases (IMIDs) and are associated with ...
Entender cómo las especies se adaptan al ambiente es aún una pregunta sin resolver en el campo de la Biología Evolutiva. Mientras el foco principal siempre ha estado en la base genética, los factores ambientales responsables ...
El objetivo de esta tesis era identificar determinantes genéticos de cáncer de mama con metástasis óseas. Para ello se utilizó un enfoque integral que se sustenta en células humanas de cáncer de mama, modelos experimentales ...

En este estudio hemos aprovechado la simplicidad numérica del sistema nervioso de la larva de la Drosophila melanogaster para identificar las neuronas responsables que dirigen sus movimientos de acuerdo a ciertas sustancias ...
Protein function is often regulated and controlled by posttranslational modifications, such as oxidation. Although oxidation has been mainly considered to be uncontrolled and nonenzymatic, many enzymatic oxidations occur ...
Upon environmental stresses such as temperature fluctuations or increases in osmolarity, yeast Saccharomyces cerevisiae induces a transcriptional reprograming in order to survive and adapt to the stress. Histone ...
In spite of recent advances in understanding the genetic bases of leukodystrophies, a large number of clinical cases remain unexplained, suggesting that many leukodystrophy-associated genes have yet to be identified. Here ...
This work focuses on the automatic identification of musical piece versions (alternate renditions of the same musical composition like cover songs, live recordings, remixes, etc.). In particular, we propose two core ...
The embryo culture system is composed by all those elements with the potential to impact embryo development. Its optimization is required to stabilize in vitro embryo culture and produce reliable and reproducible results ...
Aquesta tesi doctoral analitza el paper que juguen la classe social i el gènere en els processos de construcció de la identitat gamer, entre el col·lectiu adolescent de 14 i 15 anys escolaritzat a Barcelona i Vic. Per ...
The primary objective of the present work is to contextualise the so-called national constitutional identity clause enshrined in current Article 4(2) TEU and, by doing so, to provide some guidance to its judicial and ...
Second language use online has become a regular practice for many Internet users reflecting the emergence of new participatory cultures in the virtual world. However, little is yet known about the processes of language use ...
Internet i la tecnologia mòbil s'han consolidat com una esfera pública de la vida, on l'èxit sovint s'equipara a la participació. En aquesta tesi s'estudia la influència d’una motivació basada en la identitat en la ...
Aquesta tesi constitueix una anàlisi de la ideologia en el discurs del diari ABC Color sobre la població indígena del Paraguai durant els anys del govern de Fernando Lugo (2008-2012). A partir de l'aproximació sociocognitiva ...
Esta tesis investiga los discursos periodísticos sobre la violencia de género de tres periódicos españoles y tres italianos, en sus páginas Facebook. Analizamos la ideología, para investigar si estas noticias remiten a una ...
La presente tesi dottorale si centra sull’opera Tetralogie di Antifonte, un sofista e oratore, vissuto ad Atene nel V secolo a.C. Le Tetralogie si compongono di tre casi giudiziali, detti dicanici, a loro volta costruiti ...
