Animal multicellular structure depends on three general mechanisms: cell adhesion, cell communication and cell differentiation. Some of these mechanisms were thought to be specific to animals. Genome sequencing of unicellular ...
La vía Wnt canónica es una vía de señalización muy conservada a lo largo de la evolución de los animales. Esta vía controla múltiples procesos como es la especificación del eje anteroposterior o el destino celular durante ...
Novel human astrovirus (HAstV) are enteric virus belonging to the Astroviridae family and were discovered 10 years ago by high-throughput sequencing. They are divided in two different clades, the HAstV-MLB including 3 ...
Melanoma is the malignant tumor arising from melanocytes and is the most aggressive of the common skin cancers. Melanoma is the tumor with the highest heritability (58%) and around 10% of cases occur in a familial context. ...
Chitin has a recognised importance in physiology but also as a biomaterial. In insects, it is the principal component of the apical extracellular matrix of epidermis, tracheae, foregut and hindgut. In these compartments, ...
Neurodevelopmental disorders (NDDs) are a group of chronic diseases in which the development of the central nervous system is impaired, resulting in disability at the neuropsychiatric, motor and/or intellectual level. Some ...
In this thesis we have covered the importance of finding underlying conservation events to better understand the regulatory mechanisms of important development orchestrators like the Hox cluster. As an example of these ...
The plant pathogen Ralstonia solanacearum is the causal agent of bacterial wilt, a highly aggressive disease responsible for important worldwide economic losses. Many virulence factors in R. solanacearum have been already ...
The regulation of the expression of virulence genes in Salmonella enterica serovar Typhimurium is an intensively studied feature of Salmonella lifestyle. How Salmonella integrates environmental signals to activate ...
Healthcare is changing, and the era of data-driven healthcare organisations is increasingly popular. Data-Driven approaches (e.g., Machine Learning, Metaheuristics, Modelling and Simulation, Data Analytics, and Data ...
The bloom of genomic data has revealed a vast amount of gene losses across all life kingdoms. However, the impact of gene loss on the evolution of the mechanisms of embryo development remains an important challenge. In ...
[cat] El virus de l'hepatitis A (HAV) s'allibera de cèl·lules infectades principalment embolcallat en membranes de la pròpia cèl·lula, formant partícules quasi embolcallades (eHAV). Es creu que la biogènesis d’eHAV podria ...
El control de la transmisión de patógenos víricos a través de la ruta fecal-oral ha adquirido recientemente relevancia e interés público. Para mantener este control, es necesario determinar indicadores apropiados para la ...
Las tecnologías de secuenciación de próxima generación (NGS) proporcionan datos potentes para investigar cuestiones biológicas y evolutivas fundamentales, como estudios relacionados con la genómica evolutiva de la adaptación ...
Encontramos una gran cantidad de información genómica en bases de datos para numerosos organismos pero existe un sesgo hacia ciertos grupos taxonómicos por el interés económico, social o sanitario. Los avances y el ...
Els mètodes electroquímics s’estan estudiant com a mètodes alternatius pel tractament de l’aigua amb la finalitat d’eliminar-ne els contaminants, tant els microbiològics com els químics, en qualsevol punt del cicle de ...
Besides classic enteric viruses such hepatitis A virus and norovirus, there are other viruses that can reach water sources without being part of their transmission route. Some of these pathogens are enveloped viruses, which ...
Esta tesis doctoral tuvo como objetivo principal identificar y cuantificar la presencia de bacterias patógenas, mediante el uso de indicadores de contaminación fecal y Legionella en aguas de riego aplicando métodos ...
[eng] Microscopy and Chromosome Conformation Capture (3C) are the two main techniques for studying the three-dimensional (3D) organization of the genome. Microscopy, allowing the visualization of genomic loci in individual ...
Long non-coding RNAs (lncRNAs) are defined as transcripts longer than 200 nucleotides that lack protein-coding potential. Although multiple examples of functional lncRNAs have been described, particularly regulating gene ...
