Per què tenim por?
La por és una emoció universal, profunda i essencial, que està directament vinculada a la supervivència. Tots en algun moment hem sentit una pressió al pit, una tensió sobtada als músculs, un calfred a la pell o un batec ...
Chicken liver is a potential reservoir of bacteriophages and phage-derived particles containing antibiotic resistance genes
Poultry meat production is one of the most important agri-food industries in the world. The selective pressure exerted by widespread prophylactic or therapeutic use of antibiotics in intensive chicken farming favours the ...
Descobreixen la clau neuronal de la meditació
Des de la dècada del 1960, i especialment des que el 1968 els Beatles van anar a l'Índia a fer un curs de meditació transcendental, moltes tècniques orientals de relaxació, com el ioga, el taitxí i la mateixa meditació ...
The Prophage and Us - Shiga Toxin Phages revisited
The authors first met in 1998 at the University of Würzburg, Germany, at the Institute of Hygiene and Microbiology, in Helge Karch's lab, where Herbert Schmidt worked as a PostDoc and Maite Muniesa visited the lab for a ...
Els nois tenen més ansietat quan estudien matemàtiques
Fa anys que en molts països occidentals es detecta una davallada de l'interès dels adolescents i els joves per cursar estudis científics i tecnològics, els anomenats STEM (de les inicials angleses de science, technology, ...
Antioxidant activity of xylooligosaccharides produced from glucuronoxylan by Xyn10A and Xyn30D and eucalyptus autohydrolysates
Antioxidant activity of xylooligosaccharides (XOS) released from beechwood and birchwood glucuronoxylans by two different xylanases, one from family GH10 (Xyn10A) and another from family GH30 (Xyn30D) was ex-amined. The ...
Genètica i aprenentatge: Com influeixen els gens en l'assoliment educatiu
El cervell és l'òrgan del pensament. El pensament es defineix com l'acte de pensar; és a dir, d'exercir la facultat de concebre, jutjar o inferir, o de considerar alguna cosa, una opinió o un conjunt d'idees sobre un tema ...
Gene ontology analysis of transcriptome data from DMBA-induced mammary tumors of rats fed a high-corn oil and a high-extra virgin olive oil diet.
Breast cancer is the most common malignancy in women world- wide, and dietary lipids are important environmental factors influencing its etiology. In this work we present data in relation to the transcriptional effects of ...
Mosquits tigre i xinxes. L'arribada de noves plagues i el ressorgiment de les eradicades
Segons l"OMS, una plaga és una població d"un ésser viu que, quan supera una determinada densitat, provoca perjudicis en les persones. A Catalunya hi ha dos insectes especialment actius a l"estiu la població dels quals es ...
Chromatin dynamics in regeneration epithelia: lessons from Drosophila imaginal discs
During the process of regeneration, a switch in the transcription program occurs in cells that contribute to the reconstruction of the missing tissue. Early signals released upon damage are integrated into the chromatin ...
Therapeutic Issues in Relapsing Enterococcus faecalis Endocarditis.
We have read with great interest the article by Daneels et al., which analyzes the treatment approach and risk of relapse in a large cohort of patients with definite Enterococcus faecalis endocarditis (EFIE). Although ...
Functional characterization of the C7ORF76 genomic region, a prominent GWAS signal for osteoporosis in 7q21.3.
Genome-wide association studies (GWAS) have repeatedly identified genetic variants associated with bone mineral density (BMD) and osteoporotic fracture in non-coding regions of C7ORF76, a poorly studied gene of unknown ...
Integrative pathway enrichment analysis of multivariate omics data
Multi-omics datasets represent distinct aspects of the central dogma of molecular biology. Such high-dimensional molecular profiles pose challenges to data interpretation and hypothesis generation. ActivePathways is an ...
Planarian Cell Number Depends on blitzschnell, a Novel Gene Family That Balances Cell Proliferation and Cell Death
Control of cell number is crucial to define body size during animal development and to restrict tumoral transformation. The cell number is determined by the balance between cell proliferation and cell death. Although many ...
Ask1 and Akt act synergistically to promote ROS-dependent regeneration in Drosophila
How cells communicate to initiate a regenerative response after damage has captivated scientists during the last few decades. It is known that one of the main signals emanating from injured cells is the Reactive Oxygen ...
WNT-FRIZZLED-LRP5/6 Signaling Mediates Posterior Fate and Prolifer-ation during Planarian Regeneration
An organizer is defined as a group of cells that secrete extracellular proteins that specify the fate of surrounding cells according to their concentration. Their function during embryogenesis is key in patterning new ...
Evaluation of methods for the concentration and extraction of viruses from sewage in the context of metagenomic sequencing
Viral sewage metagenomics is a novel field of study used for surveillance, epidemiological studies, and evaluation of waste water treatment efficiency. In raw sewage human waste is mixed with household, industrial and ...
Genetics and Genomics of SOST: functional analysis of variants and genomic regulation in osteoblasts
SOST encodes the sclerostin protein, which acts as a key extracellular inhibitor of the canonical Wnt pathway in bone, playing a crucial role in skeletal development and bone homeostasis. The objective of this work was to ...
CAPTVRED: An automated pipeline for viral tracking and discovery from capture-based metagenomics samples.
Summary: Target Enrichment Sequencing or Capture-based metagenomics has emerged as an approach of interest for viral metagenomics in complex samples. However, these datasets are usually analyzed with standard downstream ...
Differential regulation of horizontally acquired and core genome genes by the bacterial modulator H-NS
Horizontal acquisition of DNA by bacteria dramatically increases genetic diversity and hence successful bacterial colonization of several niches, including the human host. A relevant issue is how this newly acquired DNA ...
