The application of NGS techniques to the study of mature B-cell neoplasms at the research level is providing a large amount of new information, in certain cases with clinical implications, which includes the identification ...
[eng] The idea of this research is to propose dimensionality reduction methods considering multi- groups in a dataset. In multivariate analysis, there are many multigroup methods, but they have different objectives than ...
During early development of bilaterian animals, specific body structures are formed and body axes are established. The establishment of body axes requires the precise and coordinated function of signalling pathways and ...
En els darrers anys l’augment poblacional així com els efectes d’un escalfament global estan minvant la capacitat i la qualitat dels recursos hídrics naturals disponibles. Els reptes als que ens enfrontem donen pas al ...
Els indicadors microbians de la contaminació fecal han estat útils al llarg dels anys pel control sanitari de la qualitat de l’aigua de consum. Tot i així, l’aigua mineral embotellada i l’aigua de la xarxa de distribució ...
The chloride channel ClCN2 is expressed in glia in the mature nervous system of vertebrates and some physiological functions have been proposed. In addition, human patients with mutations in the gene or dysfunction of the ...
The pathogenic strains of Escherichia coli can be divided into two large groups: those that cause intestinal infections and those that cause extra- intestinal infections. The strains that belong to the first group are ...
Dos dels virus entèrics humans més rellevants en l’àmbit de la salut pública i la seguretat alimentària són els HuNoV, causants de gastroenteritis aguda (GEA) esporàdica i epidèmica, i l’HAV, la principal causa d’hepatitis ...
Aromatase inhibitors (AI) are one of the main therapies to treat estrogen-receptor positive breast cancer. AI use is associated with several side effects that affects patient’s quality of life and reduces treatment adherence. ...
En aquest treball s’ha caracteritzat una col·lecció de 150 soques de C. jejuni de diferents orígens: 50 aïllaments provinents d’humans, 50 aïllaments provinents de pollastres d’engreix i 50 aïllaments provinents de diferents ...
[cat] Un dels pilars bàsics que componen la raó de ser dels parcs zoològics actuals és la conservació ex situ d’espècies amenaçades. Aquesta comesa, comporta el compliment d’una sèrie de requisits, entre ells, el de ...
El establecimiento de conexiones sinápticas específicas entre neuronas es esencial para la formación de los circuitos neuronales. En muchos sistemas esto requiere de una extensión hacia una capa sináptica concreta y la ...
Las proteínas codificadas por los genes del grupo Polycomb (PcG) constituyen un sistema clave de silenciamiento epigenético. Actúan en forma de complejos multiproteicos y modulan el estado de la cromatina mediante ...
[eng] During the last decade, advances in high-throughput sequencing (HTS) technologies have increased exponentially the generation of genomic data, especially of non-model species. In this thesis, we generated and used ...
How populations differentiate and become new species is a foundational question to the field of evolutionary biology and has important implications for the generation of both local and global patterns of species-level ...
In the present work, we studied the evolution of alternative splicing (AS) from different perspectives. First, we performed a preliminary analysis where we identified alternative exons with tissue-specific regulation in ...
The transcription factor NR2E3 participates in photoreceptor cell fate determination as it functions as both transcriptional repressor of cone genes and activator of rod genes. Mutations in NR2E3 cause retinitis pigmentosa ...
Recientemente, el interés en la celulosa se ha desplazado hacia materiales de la nanoescala que incluyen las nanofibrillas de celulosa (NFC), los nanocristales de celulosa (NCC) y la celulosa bacteriana (CB). La CB es un ...
Osteoporosis is a general skeletal disorder. It is characterized by a low bone mass and a microarchitectural deterioration of bone tissue, which increase bone fragility and susceptibility to fracture. LRP5 is a widely ...
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental, complex and highly heritable disorder characterised by age-inappropriate symptoms of inattention, impulsivity and hyperactivity that impair the daily ...
