Abstract: El pràcticum és un entorn privilegiat per a la transferència de competències. Des d’aquesta perspectiva, s’ha desenvolupat el projecte Anàlisi i avaluació de la transferibilitat de competències professionals de l’Educació Social en els centres de pràctiques (2008MQD155) a la Universitat de Barcelona durant els cursos 2008-2010. La complexitat de l’objecte d’estudi aconsellava la utilització de mètodes qualitatius. Es va optar per un disseny d’investigació-acció a partir d’espais de reflexió. Des de la percepció dels participants, s’han identificat un conjunt d’elements que afavoreixen la transferència de competències en el marc del pràcticum, entre els quals cal destacar la necessitat d’una planificació conjunta i d’una planificació específica des de cadascun dels escenaris formatius vertebrada des de la reflexió-acció de la pràctica de l’estudiant. Per fer-ho possible, és necessari que els centres de pràctiques i els centres universitaris es reconeguin corresponsables de la formació pràctica. ____________________________________________________ La formation pratique est un environnement privilégié pour le transfert de compétences. Depuis ce point de vue, l’Université de Barcelone a développé le projet “Analyse et évaluation du transfert des compétences professionnelles de l'éducation Sociale dans les établissements de formation pratique” (2008MQD155) pendant les cours 2008-2010. La complexité de l'objet d'étude demandait l'utilisation de méthodes qualitatifs. L’option élue a été la recherche-action à partir d'espaces de réflexion. Depuis l'aper u des participants, ils se sont identifié un ensemble d'éléments qu'ils aident le transfert de compétence dans la formation practique. La recherche souligne le besoin d'une planification conjointe et d'une planification spécifique de chacun des environnements formatifs. Ces planifications doivent se structurer depuis la réflexion-action de la pratique de l'étudiant. Pour celà, il est indispensable que les établissements de stage practique et l’Université soient corresponsables de la formation pratique. El prácticum es un entorno privilegiado para la transferencia de competencias. Desde esta perspectiva, se ha desarrollado el proyecto Análisis y evaluación de la transferibilidad de las competencias profesionales de la Educación Social en los centros de prácticas (2008MQD155) en la Universidad de Barcelona durante los cursos 2008-2010.

Abstract: The influenza A virus RNA polymerase is a heterotrimeric complex responsible for viral genome transcription and replication in the nucleus of infected cells. We recently carried out a proteomic analysis of purified polymerase expressed in human cells and identified a number of polymerase-associated cellular proteins. Here we characterise the role of one such host factors, SFPQ/PSF, during virus infection. Down-regulation of SFPQ/PSF by silencing with two independent siRNAs reduced the virus yield by 2–5 log in low-multiplicity infections, while the replication of unrelated viruses as VSV or Adenovirus was almost unaffected. As the SFPQ/PSF protein is frequently associated to NonO/p54, we tested the potential implication of the latter in influenza virus replication. However, down-regulation of NonO/p54 by silencing with two independent siRNAs did not affect virus yields. Down-regulation of SFPQ/PSF by siRNA silencing led to a reduction and delay of influenza virus gene expression. Immunofluorescence analyses showed a good correlation between SFPQ/PSF and NP levels in infected cells. Analysis of virus RNA accumulation in silenced cells showed that production of mRNA, cRNA and vRNA is reduced by more than 5-fold but splicing is not affected. Likewise, the accumulation of viral mRNA in cicloheximide-treated cells was reduced by 3-fold. In contrast, down-regulation of SFPQ/PSF in a recombinant virus replicon system indicated that, while the accumulation of viral mRNA is reduced by 5-fold, vRNA levels are slightly increased. In vitro transcription of recombinant RNPs generated in SFPQ/PSF-silenced cells indicated a 4–5-fold reduction in polyadenylation but no alteration in cap snatching. These results indicate that SFPQ/PSF is a host factor essential for influenza virus transcription that increases the efficiency of viral mRNA polyadenylation and open the possibility to develop new antivirals targeting the accumulation of primary transcripts, a very early step during infection.

Abstract: Background Congenital malformations are present in approximately 2–3% of liveborn babies and 20% of stillborn fetuses. The mechanisms underlying the majority of sporadic and isolated congenital malformations are poorly understood, although it is hypothesized that the accumulation of rare genetic, genomic and epigenetic variants converge to deregulate developmental networks. Methodology/Principal Findings We selected samples from 95 fetuses with congenital malformations not ascribed to a specific syndrome (68 with isolated malformations, 27 with multiple malformations). Karyotyping and Multiplex Ligation-dependent Probe Amplification (MLPA) discarded recurrent genomic and cytogenetic rearrangements. DNA extracted from the affected tissue (46%) or from lung or liver (54%) was analyzed by molecular karyotyping. Validations and inheritance were obtained by MLPA. We identified 22 rare copy number variants (CNV) [>100 kb, either absent (n = 7) or very uncommon (n = 15, <1/2,000) in the control population] in 20/95 fetuses with congenital malformations (21%), including 11 deletions and 11 duplications. One of the 9 tested rearrangements was de novo while the remaining were inherited from a healthy parent. The highest frequency was observed in fetuses with heart hypoplasia (8/17, 62.5%), with two events previously related with the phenotype. Double events hitting candidate genes were detected in two samples with brain malformations. Globally, the burden of deletions was significantly higher in fetuses with malformations compared to controls. Conclusions/Significance Our data reveal a significant contribution of rare deletion-type CNV, mostly inherited but also de novo, to human congenital malformations, especially heart hypoplasia, and reinforce the hypothesis of a multifactorial etiology in most cases.
