A Study on the Actual Use of Digital Competence in the Practicum of Education Degree.

Política de acceso abierto tomada de: https://v2.sherpa.ac.uk/id/publication/36187?template=romeoDespite the existence of many programs and training projects in the field of ICT, in post-secondary education, the teaching and learning process continues to be supported by traditional classroom methods. This phenomenon can be particularly observed in education degrees, even though future teachers are expected to acquire the necessary digital skills in order to carry out their work properly. The purpose of this study is to explore in greater depth the use of 2.0 applications in the education training of future teachers, as well as to outline the different correlations between the use of these 2.0 tools and their perceived level of digital competence, age and their level of motivation. For it, a quasi-experimental, ex post facto research was carried out with a sample of 108 future teachers from the Faculty of Education, Pontifical University of Salamanca (UPSA). The results have shown that future teachers have a low level of attitude of use towards ICT in the classroom, with an average of 2.29 based on five points. Furthermore, the results have revealed that the level of digital competence and the motivation to use ICT are two variables that correlate positively, while other variables do not show any correlation, such as age

Identification of Variables that Predict Teachers’ Attitudes toward ICT in Higher Education for Teaching and Research: A Study with Regression

The aim of this research is to analyse the attitudes towards information and communication technologies (ICT) of higher education teachers from an affective, cognitive and behavioural model for teaching and research. It also aimed to explore different factors that can predict such attitudes. A non-experimental study was proposed using a survey technique and descriptive and inferential analyses were carried out using a multiple linear regression model (MLR). In total, the sample was formed by 867 university professors from Spain belonging to different areas of knowledge. The results show that these teachers have a medium total attitudinal level, so the lowest attitudes have been represented by the behavioural ones, followed by the affective ones. Regarding the predictor variables, variables that can predict such attitudes were found to be age, participation in projects, gender and teaching in face-to-face and/or online universities (ordered from highest to lowest priority)

Influence of pore size in protein G'-grafted mesoporous silica nanoparticles as a serum pretreatment system for in vitro allergy diagnosis

Particles with the capacity to bind to immunoglobulin G (IgG) can be used for the purification of IgG or to process clinical samples for diagnostic purposes. For in vitro allergy diagnosis, the high IgG levels in serum can interfere with the detection of allergen-specific IgE, the main diagnostic biomarker. Although commercially available, current materials present a low IgG capture capacity at large IgG concentrations or require complex protocols, preventing their use in the clinic. In this work, mesoporous silica nanoparticles are prepared with different pore sizes, to which IgG-binding protein G’ is grafted. It is found that for one particular optimal pore size, the IgG capture capacity of the material is greatly enhanced. The capacity of this material to efficiently capture human IgG in a selective way (compared to IgE) is demonstrated in both solutions of known IgG concentrations as well as in complex samples, like serum, from healthy controls and allergic patients using a simple and fast incubation protocol. Interestingly, IgG removal using the best-performing material enhances in vitro IgE detection in sera from patients allergic to amoxicillin. These results highlight the great translation potential of this strategy to the clinic in the context of in vitro allergy diagnosis.Funding for Open Access charge: Universidad de Málaga/CBUA.

Diagnosis of immediate reactions to amoxicillin: Comparison of basophil activation markers CD63 and CD203c in a prospective study

Amoxicillin (AX) combined or not with clavulanic acid (CLV) is frequently involved in IgE-mediated reactions. Drug provocation test (DPT) is considered as the gold standard for diagnosis, although contraindicated in high-risk patients. Basophil activation test (BAT) can help diagnose immediate reactions to beta-lactams, although controversy exists regarding the best activation marker. We have performed a real-life study in a prospective cohort to analyze the real value of BAT as diagnostic tool and the best activation marker, CD63 and CD203c, for the evaluation of immediate reactions to these drugs.We thank Claudia Corazza for her invaluable English language support; Verónica Prados and Ana Molina for their help in technical support in flow cytometry methods.

LPS promotes Th2 dependent sensitisation leading to anaphylaxis in a Pru p 3 mouse model

Pru p 3 is the major peach allergen in the Mediterranean area. It frequently elicits severe reactions, limiting its study in humans, raising the need for animal models to investigate the immunological mechanisms involved. However, no anaphylaxis model exists for Pru p 3. We aimed to develop a model of peach anaphylaxis by sensitising mice with Pru p 3 in combination with lipopolysaccharide (LPS) as an adjuvant. Four groups of mice were sensitised intranasally: untreated; treated with Pru p 3; treated with LPS; treated with Pru p 3 + LPS. After sensitisation mice were intraperitoneally challenged with Pru p 3 and in vivo and in vitro parameters were evaluated. Only mice in the Pru p 3 + LPS group showed anaphylaxis symptoms, including a decrease in temperature. Determination of in vitro parameters showed a Th2 response with an increase of Pru p 3-specific IgE and IgG1. Moreover, at the cellular level, we found increased levels of IgE and IgG1 secreting Pru p 3-specific cells and a proliferative CD4+ T-cell response. These results demonstrate that Pru p 3-specific anaphylaxis can be generated after nasal sensitisation to Pru p 3 in combination with LPS. This is a promising model for evaluating food allergy immunotherapies.Unión Europea, Ministerio de Economía y Competitividad, Instituto de Salud "Carlos III" PI12 / 02481Unión Europea, Ministerio de Economía y Competitividad, Instituto de Salud "Carlos III" PI15 / 00559Unión Europea, Ministerio de Economía y Competitividad, Instituto de Salud "Carlos III" RD 07/0064Unión Europea, Ministerio de Economía y Competitividad, Instituto de Salud "Carlos III" RD12 / 0013/0001Unión Europea, Ministerio de Economía y Competitividad, Instituto de Salud "Carlos III" RD07 / 0064/0003Unión Europea, Ministerio de Economía y Competitividad, Instituto de Salud "Carlos III" RD12 / 0013/0016Unión Europea, Ministerio de Andalucía Economía y Conocimiento CTS-7433Unión Europea, Ministerio de Andalucía Economía y Conocimiento C-0044-2012 SAS2013Unión Europea, Ministerio de Andalucía Economía y Conocimiento Ref.

The Helicobacter pylori Genome Project : insights into H. pylori population structure from analysis of a worldwide collection of complete genomes

Helicobacter pylori, a dominant member of the gastric microbiota, shares co-evolutionary history with humans. This has led to the development of genetically distinct H. pylori subpopulations associated with the geographic origin of the host and with differential gastric disease risk. Here, we provide insights into H. pylori population structure as a part of the Helicobacter pylori Genome Project (HpGP), a multi-disciplinary initiative aimed at elucidating H. pylori pathogenesis and identifying new therapeutic targets. We collected 1011 well-characterized clinical strains from 50 countries and generated high-quality genome sequences. We analysed core genome diversity and population structure of the HpGP dataset and 255 worldwide reference genomes to outline the ancestral contribution to Eurasian, African, and American populations. We found evidence of substantial contribution of population hpNorthAsia and subpopulation hspUral in Northern European H. pylori. The genomes of H. pylori isolated from northern and southern Indigenous Americans differed in that bacteria isolated in northern Indigenous communities were more similar to North Asian H. pylori while the southern had higher relatedness to hpEastAsia. Notably, we also found a highly clonal yet geographically dispersed North American subpopulation, which is negative for the cag pathogenicity island, and present in 7% of sequenced US genomes. We expect the HpGP dataset and the corresponding strains to become a major asset for H. pylori genomics
