Complete Characterization of the O-Antigen from the LPS of Aeromonas bivalvium
Aeromonas species are found in the aquatic environment, drinking water, bottled mineral water, and different types of foods, such as meat, fish, seafood, or vegetables. Some of these species are primary or opportunistic ...
Somriures, immigració i interculturalitat
Fa un parell de setmanes, aquest diari va oferir una entrevista a Fàtima Taleb, la primera regidora musulmana de Badalona. Cap al final, Taleb diu, referint-se a l'actual alcalde en funcions: 'Ningú em robarà el somriure.' ...
First molecular phylogeny of the freshwater planarian genus Girardia (Platyhelminthes: Tricladida) unveils hidden taxonomic diversity and initiates resolution of its historical biogeography
The genus Girardia (Platyhelminthes: Tricladida) comprises several species of which some have spread from their original areas of distribution in the Americas to other parts of the globe. Due to great anatomical similarity ...
Neurones que viuen una experiència religiosa
Una de les frases que s'han fet més famoses del filòsof, economista, periodista i intel·lectual comunista Karl Marx és que 'la religió és l'opi del poble'. Més enllà de la intenció amb què ho va dir en el seu context, s'ha ...
Medical image editing in the latent space of Generative Adversarial Networks
We consider a set of arithmetic operations in the latent space of Generative Adversarial Networks (GANs) to edit histopathological images. We analyze thousands of image patches from whole-slide images of breast cancer ...
Drosophilids from the Font Groga site (Barcelona): a new collection
On 6th October 2015, we obtained a new collection of drosophilids from the Font Groga site (Barcelona, Spain). This location presents excellent environmental conditions for the study of drosophilid diversity, and a complete ...
Evaluation of the CALIOPE air quality forecasting system for epidemiological research: the example of NO2 in the province of Girona (Spain)
Background Air quality models are being increasingly used to estimate long-term individual exposures to air pollution in epidemiological studies. Most of them have been evaluated against measurements from a limited number ...
Estos virus nos ayudan a detectar materia fecal y patógenos en el agua
El agua es esencial para mantener la vida en nuestro planeta. Pero es también una matriz que permite la transmisión dentro de la biosfera de algunos agentes causantes de enfermedades, como la diarrea, que provoca 485 000 ...
Naked mole rat TRF1 safeguards glycolytic capacity and telomere replication under low oxygen.
The naked mole rat (NMR), a long-lived and cancer-resistant rodent, is highly resistant to hypoxia. Here, using robust cellular models wherein the mouse telomeric protein TRF1 is substituted by NMR TRF1 or its mutant forms, ...
Analysis of SARS-CoV-2 in wastewater for prevalence estimation and investigating clinical diagnostic test biases
Here we analyze SARS-CoV-2 genome copies in Catalonia's wastewater during the Omicron peak and develop a mathematical model to estimate the number of infections and the temporal relationship between reported and unreported ...
Molecular signatures of aneuploidy-driven adaptive evolution.
Alteration of normal ploidy (aneuploidy) can have a number of opposing effects, such as unbalancing protein abundances and inhibiting cell growth but also accelerating genetic diversification and rapid adaptation. The ...
Quantification of human adenoviruses in European recreational waters
The presence of human adenoviruses in recreational water might cause disease in the population upon exposure. Human adenoviruses detected by PCR could also serve as indicators of the virological water quality. In order to ...
L'herència dels traumes
Un estudi demostra que els fets traumàtics que el pare hagi pogut viure un temps abans de la concepció d"un fill afecten el creixement del futur nadó. La causa se situaria en els canvis epigenètics provocats pel trauma en ...
Retinoic Acid metabolic genes, meiosis, and gonadal sex differentiation in zebrafish.
To help understand the elusive mechanisms of zebrafish sex determination, we studied the genetic machinery regulating production and breakdown of retinoic acid (RA) during the onset of meiosis in gonadogenesis. Results ...
Comprehensive exploration of the genetic contribution of the dopaminergic and serotonergic pathways to psychiatric disorders
Psychiatric disorders are highly prevalent and display considerable clinical and genetic overlap. Dopaminergic and serotonergic neurotransmission have been shown to play an important role in many psychiatric disorders. ...
Hha has a defined regulatory role that is not dependent upon H-NS or StpA
The Hha family of proteins is involved in the regulation of gene expression in enterobacteria by forming complexes with H-NS-like proteins. Whereas several amino acid residues of both proteins participate in the interaction, ...
Data on the generation of two Nr2e3 mouse models by CRISPR / Cas9D10A nickase
NR2E3 encodes an orphan nuclear receptor that plays a dual function as both transcriptional activator and repressor in photoreceptors, being necessary for cone fate inhibition as well as rod differentiation and homeostasis. ...
Roles of brca2 (fancd1) in Oocyte Nuclear Architecture, Gametogenesis, Gonad Tumors, and Genome Stability in Zebrafish
Mild mutations in BRCA2 (FANCD1) cause Fanconi anemia (FA) when homozygous, while severe mutations cause common cancers including breast, ovarian, and prostate cancers when heterozygous. Here we report a zebrafish brca2 ...
Oxigen i energia
Respirar està indissociablement lligat a la vida humana. Ho fem per primer cop quan naixem, i no deixem de fer-ho fins al darrer alè de la nostra vida. Respirem per poder agafar l'oxigen de l'aire. Tots sabem què és l'oxigen. ...
Bone development and remodeling in metabolic disorders
There are many metabolic disorders that present with bone phenotypes. In some cases, the pathological bone symptoms are the main features of the disease whereas in others they are a secondary characteristic. In general, ...
