Beure llet materna i el contacte amb la natura enforteixen el sistema immunitari
L'Organització Mundial de la Salut (OMS) recomana, sempre que no hi hagi contraindicacions mèdiques, que els nadons s'alimentin exclusivament amb llet materna fins als sis mesos d'edat. I també recomana que l'alletament ...
Inhibition of cellular protein secretion by norwalk virus nonstructural protein p22 requires a mimic of an endoplasmic reticulum export signal.
Protein trafficking between the endoplasmic reticulum (ER) and Golgi apparatus is central to cellular homeostasis. ER export signals are utilized by a subset of proteins to rapidly exit the ER by direct uptake into COPII ...
Contribution of cropland to the spread of Shiga toxin phages and the emergence of new Shiga toxin-producing strains
A growing interest in healthy eating has lead to an increase in the consumption of vegetables, associated with a rising number of bacterial outbreaks related to fresh produce. This is the case of the outbreak in Germany, ...
L'exposició prenatal a ftalats pot causar endarreriments en el llenguatge
La química és present a tot arreu. Tota la natura està formada de compostos químics, i de fet la vida mateixa és una propietat emergent de la química. Sense molècules químiques, o si les reaccions químiques no fossin ...
A review of the Tripterygion tripteronotus (Risso, 1810) complex, with a description of a new species from the Mediterranean Sea (Teleostei: Tripterygiidae)
We compared specimens of Tripterygion tripteronotus from 52 localities of the Mediterranean Sea and adjacent waters, using four gene sequences (12S rRNA, tRNA-valine, 16S rRNA and COI) and morphological characters. Two ...
An equivalence approach to the integrative analysis of feature lists
Background Although a few comparison methods based on the biological meaning of gene lists have been developed, the goProfiles approach is one of the few that are being used for that purpose. It consists of projecting lists ...
Biologia, rituals i religiositat (I)
Tradicionalment hem pensat que la fe és fruit d"una elecció personal. Tanmateix, si el fet religiós és universal, no podria ser que la nostra biologia l"estigués també propiciant?
Mitochondrial gymnastics in retinal cells: a resilience mechanism against oxidative stress and neurodegeneration
Inherited retinal dystrophies (IRDs) are a broad group of neurodegenerative disorders associated with reduced or deteriorating visual system. In the retina, cells are under constant oxidative stress, leading to elevated ...
Pth reloaded: a new evolutionary perspective
The parathyroid hormone (PTH) family is a group of structurally-related secreted peptides involved in bone mineral homeostasis and multitude of developmental processes in vertebrates. These peptides mediate actions through ...
La parentalitat negativa afavoreix els estats depressius dels fills a través de modificacions epigenètiques
No és fàcil ser pare o mare, i ningú neix ensenyat. Hi ha moltes maneres d'educar els fills, les quals condicionen la percepció que tindran d'ells mateixos i el caràcter que manifestaran quan siguin adults. I, en conseqüència, ...
Evolution by gene loss
The recent increase in genomic data is revealing an unexpected perspective of gene loss as a pervasive source of genetic variation that can cause adaptive phenotypic diversity. This novel perspective of gene loss is raising ...
CRISPR/Cas9-mediated allele-specific disruption of a dominant COL6A1 pathogenic variant improves collagen VI network in patient fibroblasts
Collagen VI-related disorders are the second most common congenital muscular dystrophies for which no treatments are presently available. They are mostly caused by dominant-negative pathogenic variants in the genes encoding ...
Herència feliç
Al genoma hi ha escrit els fonaments de com pensem i actuem a través de les xarxes neurals. Un estudi publicat la setmana passada a Psycological Science demostra que la propensió a ser feliços ve controlada per gens que ...
Occurrence of pathogens in the river-groundwater interface in a losing river stretch (Besòs River Delta, Spain).
The aim of this study is to investigate the occurrence of faecal indicator and microbial pathogens (bacteria and virus) in the shallow urban aquifer of the Besòs River Delta (NE Spain). To this end, human adenovirus (HAdV) ...
Llenguatge i decisions morals
'Què faries si l"única manera de salvar cinc persones d"una mort segura a causa d"un accident atzarós fos provocar expressament la mort d"una altra persona que no està en perill?" No és una pregunta fàcil, ni la resposta ...
La biologia del racisme
El racisme és una xacra que afecta a totes les societats. És un concepte que apliquem a contextos diferents, des de la discriminació en funció de l'origen personal, que deduïm a partir de la fesomia, fins a l'aversió, i ...
Thermal evolution of gene expression profiles in Drosophila subobscura
Background: Despite its pervasiveness, the genetic basis of adaptation resulting in variation directly or indirectly related to temperature (climatic) gradients is poorly understood. By using 3-fold replicated laboratory ...
Identifiquen la signatura neuronal del 'flow'
Fa alguns anys es va posar de moda l'expressió 'tenir flow ' per referir-se a la sensació de desimboltura plaent que de vegades es té quan es realitza una activitat. En l'àmbit de la psicologia es fa servir per referir-se ...
Interannual fluctuations in connectivity among crab populations (Liocarcinus depurator) along the Atlantic-Mediterranean transition.
An interesting evolutionary question that still remains open is the connectivity between marine populations. Marine currents can favour the dispersal of larvae or adults, but they can also produce eddies and gyres generating ...
Raw sewage harbors diverse viral populations
At this time, about 3,000 different viruses are recognized, but metagenomic studies suggest that these viruses are a small fraction of the viruses that exist in nature. We have explored viral diversity by deep sequencing ...
