[eng] In the last decades biological invasions have emerged as a global concern, as they impact local biodiversity by disrupting ecosystem functioning and ultimately affect human health, economy and wellness. In a climate ...
The tracheal (respiratory) system of the Drosophila embryo is a network of interconnected epithelial tubes that supplies and exchanges the gas to maintain the homeostasis of the entire organism. Maintaining a controlled ...
Histone H1 is a key determinant of higher-order chromatin structures and for a long time it has been considered a main transcriptional repressor. So consistent with its biochemical properties, the absence of histone H1 was ...
Seven linker histone H1 variants are present in human somatic cells with distinct prevalence across cell types. Using variant-specific antibodies to H1 and hemagglutinin-tagged recombinant H1 variants expressed in breast ...
In the Drosophila larva, most of the juvenile tissues are made up of large polyploid cells fated to die during metamorphosis stage. The dorsal trunk of the tracheal system is composed mainly of these cells, apart from the ...
La mayoría de las transacciones del genoma producen estrés topológico en el ADN, que se reduce gracias a la acción de las topoisomerasas. Por ejemplo, durante la transcripción y replicación del ADN, las topoisomerasas I y ...
La malaltia de von Willebrand (VWD) és la patologia hemorràgica hereditària més freqüent a la població i està causada per dèficits quantitatius o qualitatius del factor von Willebrand (VWF). Segons el defecte, es distingeixen ...
L’objectiu global plantejat en aquesta tesi ha estat l’anàlisi dels patògens virals que a través de l’aigua residual, poden contaminar l’aigua de reg i els aliments. Les aigües regenerades i les aigües de riu són importants ...
El objetivo global de esta tesis es ampliar el conocimiento sobre la biología y ecología del rorcual común, con foco principal en la población de rorcual común de Islandia. Dadas las numerosas incógnitas que siguen existiendo ...
Development requires an increment of cell growth and cell number, concomitant to a tightly control of cell differentiation. Thanks to cell communication, cells can be spatiotemporal patterned to acquire the required fate. ...
Polycyclic aromatic hydrocarbons (PAHs) are major environmental pollutants in a number of point source contaminated sites, where they are found embedded in complex mixtures containing different polyaromatic compounds. The ...
[spa] En las últimas décadas la resistencia a antibióticos se ha convertido en uno de los principales problemas de salud pública a nivel global, y desde la iniciativa One-Health se han propuesto afrontar este problema, ...
La agencia europea del medicamento, EMA, y la estadounidense FDA, propusieron límites de bioequivalencia (BE) “escalada” para facilitar la declaración BE de genéricos de drogas de alta variabilidad (HVD). La ...
Mining industry faces environmental problems concerning waste management. Given the environmental issues associated with storage of mine wastes on land, one disposal option that has gained attraction is submarine tailings ...
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 ...
[eng] Inherited Retinal Dystrophies (IRDs) are a clinically and genetically highly heterogeneous group of genetic pathologies characterized by progressive attrition of photoreceptor cells and other retinal neurons, which ...
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, ...
