Characterization of the TLR family in branchiostoma lanceolatum and discovery of a novel TLR22-like involved in dsRNA recognition in amphioxus
Toll-like receptors (TLRs) are important for raising innate immune responses in both invertebrates and vertebrates. Amphioxus belongs to an ancient chordate lineage which shares key features with vertebrates. The genomic ...
Un cos amb nyaps
El Poema de Gilgamesh, escrit al voltant de l'any 1400 aC a partir de diversos textos sumeris més antics, és un dels primers de què es té constància escrita. No obstant, el més antic que es conserva, de fa més de 4.000 ...
Breast milk immune composition varies during the transition stage of lactation: characterization of immunotypes in the MAMI cohort
<strong>Background:</strong> Breast milk is a complex and dynamic fluid needed for infant development and protection due to its content of bioactive factors such as immunoglobulins (Igs). Most studies focus primarily on ...
Multi-omic profiling of a newly isolated Oxy-PAH degrading specialist from PAH-contaminated soil reveals bacterial mechanisms to mitigate the risk posed by polar transformation products
Polar biotransformation products have been identified as causative agents for the eventual increase in genotoxicity observed after the bioremediation of PAH-contaminated soils.Their further biodegradation has been described ...
El nom (no) fa la cosa
S'acostuma a dir que el nom no fa la cosa. Fins i tot el DIEC ho fa servir en una de les accepcions del mot 'cosa', 'allò que és real, concret'. Anomenar una cosa no altera la seva realitat física, però condiciona la ...
Genome-wide DNA methylation analysis in an antimigraine-treated preclinical model of cortical spreading depolarization
Background: Cortical spreading depolarization, the cause of migraine aura, is a short-lasting depolarization wave that moves across the brain cortex, transiently suppressing neuronal activity. Prophylactic treatments for ...
Mediterranean Sea heatwaves jeopardize greater amberjack's (Seriola dumerili) aquaculture productivity through impacts on the fish microbiota
Climate change is dramatically increasing the frequency and severity of marine heatwaves (MHWs) in the Mediterranean basin, strongly affecting marine food production systems. However, how it will shape the ecology of ...
L'herència cultural de les orques àvies
Únicament hi ha tres espècies de mamífers en què les femelles passen, dins el seu cicle vital, per una fase de menopausa a la qual segueix una llarga etapa vital postmenopàusica. Des d'una perspectiva genètica i evolutiva ...
El análisis canónico y su aplicación en Geologia
Se exponen los fundamentos del análisis canóiiico, combinación del análisis de la varianza y del factorial, así como sus posibles aplicaciones a los problemas geológicos.
Evolutionary dynamics of molecular markers during local adaptation: a case study in Drosophila subobscura
Background: Natural selection and genetic drift are major forces responsible for temporal genetic changes in populations. Furthermore, these evolutionary forces may interact with each other. Here we study the impact of an ...
The Deubiquitinating Enzyme Ataxin-3 Regulates Ciliogenesis and Phagocytosis in the Retina
Expansion of a CAG repeat in ATXN3 causes the dominant polyglutamine disease spinocerebellar ataxia type 3 (SCA3), yet the physiological role of ATXN3 remains unclear. Here, we focus on unveiling the function of Ataxin-3 ...
Cervells confinats
Som una espècie social abocada a un confinament obligat i necessari. Molts l'estem passant acompanyats, però hi ha persones que estan soles. Sigui com sigui, el cercle social de contactes presencials s'ha reduït dràsticament. ...
Socilització científica
La ciència <br>definida com el conjunt de coneixences d'un cert ordre de coses<br> i la tècnica <br>que és l'aplicació de la ciència tenen un impacte cabdal en tots els aspectes de la nostra vida, i hi confiem bona part ...
Interobserver and Intertest Agreement in Telemedicine Glaucoma Screening with Optic Disk Photos and Optical Coherence Tomography
t: Purpose: To evaluate interobserver and intertest agreement between optical coherence tomography (OCT) and retinography in the detection of glaucoma through a telemedicine program. Methods: A stratified sample of 4113 ...
Hints for Metal-Preference Protein Sequence Determinants: Different Metal Binding Features of the Five Tetrahymena thermophila Metallothioneins
The metal binding preference of metallothioneins (MTs) groups them in two extreme subsets, the Zn/Cd - and the Cu - thioneins. Ciliates harbor the largest MT gene/protein family reported so far, i n- cluding 5 paralogs ...
Emocions cardíaques
Fa unes setmanes es va celebrar a Barcelona un concorregut congrés mundial de cardiologia, del qual han informat a bastament i amb puntualitat els mitjans de comunicació. Durant el congrés els especialistes ens han recordat ...
Tracking Invasion Histories in the Sea: Facing Complex Scenarios Using Multilocus Data
In recent years, new analytical tools have allowed researchers to extract historical information contained in molecular data, which has fundamentally transformed our understanding of processes ruling biological invasions. ...
Multiancestry genome-wide association study of 520,000 subjects identifies 32 loci associated with stroke and stroke subtypes
Stroke has multiple etiologies, but the underlying genes and pathways are largely unknown. We conducted a multiancestry genome-wide-association meta-analysis in 521,612 individuals (67,162 cases and 454,450 controls) and ...
Phenotypic spectrum and transcriptomic profile associated with germline variants in TRAF7
Purpose: Somatic variants in tumor necrosis factor receptor-associated factor 7 (TRAF7) cause meningioma, while germline variants have recently been identified in seven patients with developmental delay and cardiac, facial, ...
