The páramo is a high mountain ecosystem that includes the natural and semi-natural habitats located between the montane treeline and the permanent snowline in the humid Northern Andes. Given its recent origin and continental ...
ARCIMBOLDO is an ab initio phasing method for macromolecular crystallographic X-ray diffraction data, which combines location of model fragments such as polyalanine α- helices with the program PHASER and density modification ...
Un dels factors pronòstics més importants en la leucèmia limfàtica crònica (LLC) són les categories de risc citogenètic, basades en la detecció de del(13q), trisomia 12, del(11q) i del(17p) per hibridació in situ fluorescent ...
Psychotic disorders including bipolar disorder and schizophrenia are a leading cause of disability across the world but the underlying pathophysiological mechanisms remain poorly understood. Available treatments are ...
La presente tesis doctoral consta de 4 proyectos independientes centrados en el estudio de las causas genéticas del cáncer colorrectal (CCR) hereditario: A) Estudio de una variante común (rs2075786) en el gen de la ...
The main objective of this PhD dissertation was to unveil the links between biogeochemistry and microbial diversity using metagenomics functional potential as a proxy to connect a mechanistic perspective with whole-system ...
La malaltia de Gaucher (GD) forma part d'un conjunt de malalties que es coneixen amb el nom de "malalties d'acumulació lisosómica". La GD n'és la més prevalent i en la majoria de casos és causada per mutacions en el gen ...
Many chemicals are continuously entering into the aquatic environment, as a result of their widespread use, disposal and accidental release. Several of these xenobiotics may disrupt reproductive functions of both vertebrates ...
The general aim of this dissertation is to investigate the evolution, the diversification and some ecological traits of the species of the strictly subterranean genus Troglocharinus Reitter, 1908. The genus Troglocharinus ...
En esta tesis doctoral se estudia el efecto de una dieta de restricción calórica de mantenimiento a largo plazo (14 meses), en machos de lubina prepúberes, sobre el inicio y desarrollo de la pubertad. Para ello se consideró ...
INTRODUCCIÓ: Actualment el bypass gàstric en Y-de-Roux és la tècnica més freqüent portada a terme en l’àmbit internacional en què, en ser de tipus mixta, es produeix una combinació dels elements restrictius i de malabsorció. ...
Plants germinated in the dark under the soil surface, undergo skotomorphogenic development. Once they emerge from the soil surface perceive light for the first time. Then, seedlings switch from skotomorphogenic to ...
Fisheries management has definitively embraced the Ecosystem Approach to Fisheries (EAF) philosophy and new management policies are incorporating integrative measures that take into account not only target species but also ...
The aim of this thesis was to explore the distribution of the taxonomic, phylogenetic and functional components of plant diversity in high mountains, and to show how different components of diversity have responded to ...
Sexual division of labour involving the use of teeth in non-masticatory activities in the Tigara population form Point Hope did not affect the wear of the upper and lower first molars and, therefore, food chewing was the ...
Breast cancer is a very heterogeneous disease with a poor prognostic outcome, largely due to its resistance to current cancer therapies. The balance between cell proliferation and apoptosis plays a critical role in determining ...
Sequence, structure and dynamics are an indivisible tandem to understand protein function. Luckily, evolution imposed a hierarchical rational between that facilitates the analysis: dynamics are encoded in the structure, ...
Macrophyte systems are globally vulnerable to overgrazing, often shifting precipitously to functionally poorer alternative stable states triggered by herbivore population outbreaks. Sea urchin herbivory can cause shifts ...
The genetic and molecular bases of most of the human diseases have become one of the main goals of the human biology in the last decades. To be able to unveil the genetic variations and the affected cellular processes ...
El mantenimiento de la homeostasis del sistema inmune innato es fundamental, ya que éste debe mantener una respuesta equilibrada frente a los patógenos. En mamíferos, uno de los mecanismos por el cual se mantiene la ...
