Discriminació, xenofòbia i violència: la cara oculta del covid-19
La vida social és complexa i per conviure de manera raonablement harmònica amb els nostres conciutadans ens cal utilitzar sovint certes dosis de tolerància. La tolerància és la disposició que tenim per aguantar i respectar ...
Las mutaciones de la conciencia de Jean Gebser: una revisión crítica desde la evolución biológica y cultural
En este artículo desarrollamos una serie de apreciaciones y consideraciones acerca de las ideas de Gebser sobra las estructuras de la conciencia y su propuesta relativa a la emergencia de una nueva conciencia. Para explicar ...
Disruption of embryonic blood-CSF barrier in chick embryos reveals the actual importance of this barrier to control E-CSF composition and homeostasis in early brain development
In vertebrates, early brain development takes place at the expanded anterior end of the neural tube. After closure of the anterior neuropore, the brain wall forms a physiologically sealed cavity that encloses embryonic ...
Body weight gain and control: beneficial effect of extra virgin olive oil versus corn oil in an experimental model of mammary cancer
Obesity is a known risk factor for breast cancer, the most common malignancy among women worldwide. We have previously described different effects of high-fat diets on mammary experimental carcinogenesis. In this work, we ...
El cervell podria reactivar sol les malalties inflamatòries
Les malalties inflamatòries poden afectar qualsevol òrgan del cos. En aquests trastorns intervé el sistema immunitari, que genera una resposta inespecífica l'objectiu de la qual és aïllar possibles agents infecciosos. Tot ...
Com s'adapten els organismes al canvi climàtic? Les inversions cromosòmiques de Drosophila subobscura: el cas de les poblacions de Sèrbia
És conegut el fet que les inversions cromosòmiques de les poblacions naturals de l'espècie Drosophila subobscura són adaptatives respecte a les variacions de l'ambient. S'ha observat que les inversions canvien en freqüència ...
Dogmes immutables
Els humans som ben curiosos: ens omplim la boca auto qualificant-nos d'animals racionals mentre fem tots els possibles per aferrar-nos a dogmes irracionals. Els dogmes són principis fonamentals, veritats universals ...
Viral metagenomics reveals persistent as well as dietary acquired viruses in Antarctic fur seals.
Viruses linked to animals inhabiting Antarctic latitudes remain poorly studied. Remote environments hosting large pinniped populations may be prone to exposure of immunologically naïve animals to new infectious agents due ...
Reappraisal of [18F]FDG-PET/CT for diagnosis and management of cardiac implantable electronic device infections
Introduction and objectives: The role of [18F]FDG-PET/CT in cardiac implantable electronic device (CIED) infections requires better evaluation, especially in the diagnosis of systemic infections. We aimed to determine the ...
Behind and beyond of the cyborgs and robots ideas and realities: some techno-scientific and philosophical hints
We are progressively immersed in technology to such extend that in our everyday life we are and we do what technology allows us to be and to do. In this process, cyborgs and robots constitute elements that we analyze from ...
Apologia de la reflexió
Acaba un nou curs a la universitat i és moment de valorar la feina feta amb els alumnes i reflexionar sobre els resultats obtinguts. És un exercici que els professors fem, o hauríem de fer, cada any, en benefici dels nostres ...
Pancrustacean evolution illuminated by taxon-rich genomic-scale data sets with an expanded remipede sampling
The relationships of crustaceans and hexapods (Pancrustacea) have been much discussed and partially elucidated following the emergence of phylogenomic data sets. However, major uncertainties still remain regarding the ...
Metallomics reveals a persisting impact of cadmium on the evolution of metal-selective snail metallothioneins
The tiny contribution of cadmium (Cd) to the composition of the earth's crust contrasts with its high biological significance, owing mainly to the competition of Cd with the essential zinc (Zn) for suitable metal binding ...
New approach for the simultaneous detection of somatic coliphages and F-specific RNA coliphages as indicators of fecal pollution
Enteric bacteriophages (somatic coliphages, F-specific coliphages or both together) are now recognized as useful viral indicators in water, shellfish, and biosolids and are being progressively included in national and ...
The avocado genome informs deep angiosperm phylogeny, highlights introgressive hybridization, and reveals pathogen-influenced gene space adaptation
The avocado, Persea americana, is a fruit crop of immense importance to Mexican agriculture with an increasing demand worldwide. Avocado lies in the anciently diverged magnoliid clade of angiosperms, which has a controversial ...
Ets una persona sociable? Dona'n les gràcies als bacteris intestinals
En els animals, les interaccions socials són imprescindibles per regular comportaments bàsics com l'aparellament, l'alimentació i la defensa. Per això el cervell controla molts aspectes d'aquestes interaccions. Tanmateix, ...
Cytoskeletal players in single-cell branching morphogenesis
Branching networks are a very common feature of multicellular animals and underlie the formation and function of numerous organs including the nervous system, the respiratory system, the vasculature and many internal glands. ...
Assessment of dead-end ultrafiltration for the detection and quantification of microbial indicators and pathogens in the drinking water treatment processes
A safe water supply requires distinct treatments and monitoring to guarantee the absence of pathogens and substances potentially hazardous for human health. In this study we assessed the efficiency of the dead-end ...
Short- and long-term changes in chromosomal inversion polymorphism and global warming: Drosophila subobscura from the Balkans
The chromosomal inversion polymorphism of Drosophila subobscura is adaptive to environmental changes. The population of Petnica, Serbia, was chosen to analyze short- and long-term changes in this polymorphism. Short-term ...
Broken colinearity of the amphioxus Hox cluster.
Background In most eumetazoans studied so far, Hox genes determine the identity of structures along the main body axis. They are usually linked in genomic clusters and, in the case of the vertebrate embryo, are expressed ...
