    There are several reasons to celebrate the latest advances in the treatment of the infection with HIV. According to the Joint United Nations Programme on HIV/AIDS, the number of new infections dropped by 15%; there is also ...

    Resistencia a la insulina inducida por acidos grasos en células de músculo esquelético L6E9: papel de la carnitina palmitoiltransferasa I (CPT-I) 

    Sebastián Muñoz, David (Date of defense: 2006-03-31)

    La resistencia a la insulina es un estado patológico que se define como la incapacidad del organismo de responder normalmente a las acciones de la insulina. Este estado está ligado a la obesidad, al estilo sedentario de ...

    Role of Notch/RBPjk signaling pathaway in embryonic hematopoiesis 

    Robert Moreno, Alexandre (Date of defense: 2007-09-28)

    The process that gives rise to all the mature blood cells from the HSCs (Hematopoietic Stem Cells) is known as hematopoiesis. In the adult, hematopoiesis takes place in the bone marrow although the HSCs are likely generated ...

    Role of the Kinases NEK6, NEK7 and NEK9 in the Regulation of the Centrosome Cycle 

    Sdelci, Sara (Date of defense: 2012-12-13)

    This thesis project is focused on the study of the signaling module formed by the NIMA-related protein Nek6, Nek7, and Nek9 and their function during early mitosis, with particular interest in centrosome separation and ...

    Role of the tumour suppressor pathway p53‐p21 in the regulation of metabolism 

    Pulice, Giuseppe (Date of defense: 2014-12-15)

    Changes in diet and life style caused an alarming increase in the incidence of obesity, which is considered a major risk factor for the onset of the metabolic syndrome. One of the initial events in obesity is adipocyte ...

    Search for new antiviral compounds using fragment screening methodology 

    Kaczmarska, Zuzanna (Date of defense: 2014-12-05)

    Picornaviridae are among the most diverse and oldest known viral families that include many important pathogens of humans and animals. They are small, icosahedral (+)ssRNA viruses, causing a variety of diseases, such as ...

    Síndrome de cáncer de mama y ovario hereditario: Estudio in vitro de variantes BRCA1 y BRCA2 de significado biológico desconocido y búsqueda de nuevos genes responsables de este síndrome 

    Quiles Vidal, Francisco de Asís (Date of defense: 2016-02-05)

    ANTECEDENTES: Entre un 20-25% de pacientes con cáncer de mama y ovario muestran historia familiar de dicha enfermedad. Una porción de estos casos son debidos a mutaciones germinales en genes de predisposición conocidos y ...
