When invasion biology meets taxonomy: Clavelina oblonga (Ascidiacea) is an old invader in the Mediterranean Sea
Taxonomic issues often confound the study of invasive species, which sometimes are unrecognized as introduced in newly colonized areas. Clavelina oblonga Herdman, 1880 is an abundant ascidian species along the southeastern ...
Drinking Water Library: nuevo recurso para identificar cepas bacterianas en aguas de consumo
De acuerdo con el RD 140/2003, el agua apta para el consumo humano no debe mostrar presencia de los indicadores bacterianos Escherichia coli, Clostridium perfringens y Enterococcus sp. Pero, aunque no se detecten estos ...
Pèls a la llengua
Si sou calbs i voleu deixar de ser-ho, o si la vostra parella és calba i enyoreu aquells cabells llargs i espessos que lluïa a l'època hippie, esteu de sort. Però aneu alerta, perquè si sou d'aquelles persones que els ...
Bacteriophages as weapons against bacterial biofilms in the food industry
Microbiological contamination in the food industry is often attributed to the presence of biofilms in processing plants. Bacterial biofilms are complex communities of bacteria attached to a surface and surrounded by an ...
Implications of free Shiga toxin-converting bacteriophages occurring outside bacteria for the evolution and the detection of Shiga toxin-producing Escherichia coli
In this review we highlight recent work that has increased our understanding of the distribution of Shiga toxin-converting phages that can be detected as free phage particles, independently of Shiga toxin-producing bacteria ...
Les interferències entre religió i ciència
Fa exactament tres mesos un grup d'investigadors catalans anunciaven la troballa als Hostalets de Pierola d'en Pau, l'últim fòssil trobat fins a l'actualitat de l'avantpassat comú de ximpanzés, goril·les i humans. A poc a ...
Quantitative risk assessment of norovirus and adenovirus for the use of reclaimed water to irrigate lettuce in Catalonia
Wastewater is an important resource in water-scarce regions of the world, and its use in agriculture requires the guarantee of acceptable public health risks. The use of fecal indicator bacteria to evaluate safety does not ...
Carbapenemase-Producing Enterobacteriaceae Recovered from a Spanish River Ecosystem
The increasing resistance to carbapenems is an alarming threat in the fight against multiresistant bacteria. The dissemination properties of antimicrobial resistance genes are supported by their detection in a diverse ...
Patterns of nucleotide diversity at the regions encompassing the Drosophila insulin-like peptide (dilp) genes: demography vs positive selection in Drosophila melanogaster.
In Drosophila, the insulin-signaling pathway controls some life history traits, such as fertility and lifespan, and it is considered to be the main metabolic pathway involved in establishing adult body size. Several ...
Llibertat de pensament
Fa un parell de mesos, a finals de febrer, vaig participar com a convidat en una taula rodona al Foro de la Cultura de Valladolid. Amb el títol general d'Odiad, malditos, l'objectiu era debatre, des de molts àmbits del ...
Projecte UBAUDIT: Plugin para el análisis e informe de calidad de cuestionarios Moodle.
UBaudit es un proyecto de la Universitat de Barcelona y CV&AConsulting dirigido a la creación de una aplicación en el entorno Moodle que permitaefectuar una auditoria automática de los cuestionarios empleados en la evaluación ...
Integrated regulation of the type III secretion system and other virulence determinants in Ralstonia solanacearum
In many plant and animal bacterial pathogens, the Type III secretion system (TTSS) that directly translocates effector proteins into the eukaryotic host cells is essential for the development of disease. In all species ...
A new spontaneous chromosomal inversion in a classical laboratory strain of <em>Drosophila subobscura</em>
Drosophila subobscura stands out for its rich chromosomal polymorphism in natural populations. Krimbas (1992) reviewed up to 66 spontaneous chromosomal inversions that combined into 79 arrangements. Some of these inversions ...
L'ansietat i la depressió, relacionades amb el càncer
L'activitat del cervell controla la fisiologia i les respostes corporals, i per això influeix en el funcionament de tot el cos. Aquest és l'origen de les malalties psicosomàtiques, com, per exemple, molts casos d'hipertensió ...
Evolución: de la especie humana al cyborg
Resumen: Gracias a la evolución biológica y cultural el ser humano ha sido capaz de adaptarse al ambiente. Una opción para mejorar las prestaciones humanas podría ser la obtención de un cyborg o ser humano biónico en el ...
Deep sequencing reveals early reprogramming of arabidopsis root transcriptomes upon ralstonia solanacearum infection
Bacterial wilt caused by the bacterial pathogen Ralstonia solanacearum is one of the most devastating crop diseases worldwide. The molecular mechanisms controlling the early stage of R. solanacearum colonization in the ...
Normal limits of home measured spatial gait parameters of the elderly population and their association with health variables
Gait studies in the elderly population have been always conducted in gait labs or spacious clinical facilities, which influence gait parameters, and also implies that the participants have to be able to move to these ...
Vigilar les calories per poder mantenir el cervell jove
Els excessos a la taula també influeixen en els mecanismes que expliquen el desenvolupament de les malalties neurodegeneratives
A conserved Shh cis-regulatory module highlights a common developmental origin of unpaired and paired fins
Despite their evolutionary, developmental, and functional importance the origin of vertebrate paired appendages remains uncertain. In mice, a single enhancer termed ZRS is solely responsible for Shh expression in limbs. ...
