Spatio-temporal variability of levels and speciation of particulate matter across Spain in the CALIOPE modeling system
The CALIOPE high-resolution air quality modeling system (4 km × 4 km, 1 h) estimates particulate matter from two aerosol models, CMAQv4.5 (AERO4) and BSC-DREAM8b. While CMAQv4.5 calculates biogenic, anthropogenic and ...
El líquid cerebroespinal. Un fluid vital per al sistema nerviós central
Moltes civilitzacions s"han desenvolupat al costat de rius i mars, uns medis fluids que han servit de vehicle de cohesió i transport i que han afavorit la supervivència de les persones que vivien a les seves ribes. Per als ...
Minimal requirements for parameters to be used for the development of predictive models for microbial source tracking. The example of the pair somatic coliphages and phages infecting Bacteroides
Several methods and approaches for measuring parameters to determine fecal sources of pollution in water have been developed in recent years. No single microbial or chemical parameter has proved sufficient to determine the ...
Les emocions negatives condicionen el comportament
La memòria és la capacitat que tenim de retenir el passat en la consciència i reproduir-lo mentalment o reviure'l reconeixent-lo de manera explícita com a passat, la qual cosa inclou la facultat de poder recuperar la ...
Viure en una gran ciutat incrementa el risc de conductes violentes
Segons el Balanç de seguretat i activitat policial fet públic pels Mossos d'Esquadra a principis del 2018, l'any 2017 es van registrar a Catalunya més de 45.000 actes de violència contra persones, inclosos assassinats i ...
Caracterizació ecofisiològica d'un mutant de Rhodobacter sphaeroides deficient en la síntesi de carotenoides
A mutant strain of Rhodobacter sphaeroides, altered in carotenoid biosynthesis. was compared to the wild type in relation to the physiological response of both strains to different light intensities (230-925 lux). Absorption ...
Differential regulation of CsrC and CsrB by CRP-cAMP in Salmonella enterica
Post-transcriptional regulation mediated by regulatory small RNAs (sRNAs) has risen as a key player in fine-tuning gene expression in response to environmental stimuli. Here, we show that, in Salmonella enterica, the central ...
Bacteris per fer electricitat
LA CIVILITZACIÓ TECNOLÒGICA en què vivim consumeix molta energia. Es calcula que cada dia cada un de nosaltres gasta directament o indirectament uns 10.000 watts de potència<br>l"equivalent a 100 làmpades de filament de ...
Variants of the aggression-related RBFOX1 gene in a population representative birth cohort study: aggressiveness, personality and alcohol use disorder
Background: Recently, RBFOX1, a gene encoding an RNA binding protein, has consistently been associated with aggressive and antisocial behavior. Several loci in the gene have been nominally associated with aggression in ...
Closed genome and comparative phylogenetic analysis of the clinical multidrug resistant Shigella sonnei strain 866
Shigella sonneiis responsible for the majority of shigellosis infections in the US with over 500,000 cases reported annually. Here, wepresent the complete genome of the clinical multidrug resistant (MDR) strain 866, which ...
Global phylogeography and ancient evolution of the widespread human gut virus crAssphage
Microbiomes are vast communities of microorganisms and viruses that populate all natural ecosystems. Viruses have been considered to be the most variable component of microbiomes, as supported by virome surveys and examples ...
Is Genetic Mobilization Considered When Using Bacteriophages in Antimicrobial Therapy?
The emergence of multi-drug resistant bacteria has undermined our capacity to control bacterial infectious diseases. Measures needed to tackle this problem include controlling the spread of antibiotic resistance, designing ...
Inversions and adaptation to the plant toxic ouabain shape DNA sequence variation within and between chromosomal inversions of Drosophila subobscura
Adaptation is defined as an evolutionary process allowing organisms to succeed in certain habitats or conditions. Chromosomal inversions have the potential to be key in the adaptation processes, since they can contribute ...
Identificación de características forenses avanzadas a partir del ADN: etnogeografía, patología delictiva y morfoanatomía
Resumen: El uso de la molécula de ADN ha revolucionado el mundo de la Genética forense, convirtiéndose en una herramienta poderosa para resolver un gran número de casos judiciales. El ADN permite identificar a una persona ...
Therapeutic strategies based on modified U1 snRNAs and chaperones for Sanfilippo C splicing mutations
Mutations affecting RNA splicing represent more than 20% of the mutant alleles in Sanfilippo syndrome type C, a rare lysosomal storage disorder that causes severe neurodegeneration. Many of these mutations are localized ...
Non-Viral Delivery of CRISPR/Cas Cargo to the Retina Using Nanoparticles: Current Possibilities, Challenges, and Limitations
The discovery of the CRISPR/Cas system and its development into a powerful genome engineering tool have revolutionized the field of molecular biology and generated excitement for its potential to treat a wide range of human ...
Extending the phenotypic spectrum of Bohring-Opitz syndrome: mild case confirmed by functional studies
Bohring-Opitz syndrome (BOS) has been described as a clinically recognizable genetic syndrome since 1999. Clinical diagnostic criteria were established in 2011 and include microcephaly, trigonocephaly, distinctive craniofacial ...
Genomic analysis of the natural history of attention-deficit/hyperactivity disorder using Neanderthal and ancient Homo sapiens samples
Attention-deficit/hyperactivity disorder (ADHD) is an impairing neurodevelopmental condition highly prevalent in current populations. Several hypotheses have been proposed to explain this paradox, mainly in the context of ...
Dejuni mental
Una de les tendències actuals de molts musulmans il·lustrats és buscar paral·lelismes entre les descobertes científiques i les escriptures de l'Alcorà. Molts textos apologètics comencen dient que "la ciència ha confirmat ...
In situ monitoring and quantitative determination of R27 plasmid conjugation
Horizontal gene transfer (HGT) by plasmid conjugation is a major driving force in the spread of antibiotic resistance among Enterobacteriaceae. Most of the conjugation studies are based on calculation of conjugation ratios ...
