Recomanacions per a la correcta identificació d’autors i institucions de la Universitat de Barcelona en les publicacions científiques

La manca de normalització dels noms dels investigadors i de la mateixa Universitat de Barcelona en les publicacions científiques i en les principals bases de dades bibliogràfiques és un fet conegut que disminueix la visibilitat dels autors i de la UB a nivell nacional i internacional. El fet que els mateixos autors variïn la forma de la seva signatura o la de la institució on treballen, utilitzant de vegades distintes formes de nom al llarg de la seva producció científica, juntament amb la possibilitat de cometre errors en la transcripció de la informació del document original a l’electrònic perjudica als investigadors i a les institucions dificultant la recuperació de les seves publicacions en les revistes i bases de dades i de les citacions per elles rebudes.La signatura normalitzada, també anomenada Nom Bibliogràfic Únic (NBU) afavoreix la recuperació de la producció científica i proporciona fiabilitat d’indicadors bibliomètrics sobre productivitat, impacte, i rànquing entre d’altres. La Universitat de Barcelona, seguint les recomanacions de la Fundación Española para la Ciencia y la Tecnología (FECYT) en el seu document: "Propuesta de manual de ayuda a los investigadores españoles para la normalización del nombre de autores e instituciones en las publicaciones científicas", aconsella als autors membres de la UB tenir en compte les següents pautes a l’hora d’elaborar la forma de signatura normalitzada del seu nom personal i per citar correctament el lloc de treball en les publicacions científiques.

Hog1 bypasses stress-mediated down-regulation of transcription by RNA polymerase II redistribution and chromatin remodeling

Cells are subjected to dramatic changes of gene expression upon environmental changes. Stresscauses a general down-regulation of gene expression together with the induction of a set of stress-responsivegenes. The p38-related stress-activated protein kinase Hog1 is an important regulator of transcription uponosmostress in yeast. Genome-wide localization studies of RNA polymerase II (RNA Pol II) and Hog1 showed that stress induced major changes in RNA Pol II localization, with a shift toward stress-responsive genes relative to housekeeping genes. RNA Pol II relocalization required Hog1, which was also localized to stress-responsive loci. In addition to RNA Pol II-bound genes, Hog1 also localized to RNA polymerase III-bound genes, pointing to a wider role for Hog1 in transcriptional control than initially expected. Interestingly, an increasing association of Hog1 with stressresponsive genes was strongly correlated with chromatin remodeling and increased gene expression. Remarkably, MNase-Seq analysis showed that although chromatin structure was not significantly altered at a genome-wide level in response to stress, there was pronounced chromatin remodeling for those genes that displayed Hog1 association. Hog1 serves to bypass the general down-regulation of gene expression that occurs in response to osmostress, and does so both by targeting RNA Pol II machinery and by inducing chromatin remodeling at stressresponsive loci.

Dissecting the role of low-complexity regions in the evolution of vertebrate proteins

Low-complexity regions (LCRs) in proteins are tracts that are highly enriched in one or a few aminoacids. Given their high abundance, and their capacity to expand in relatively short periods of time through replication slippage, they can greatly contribute to increase protein sequence space and generate novel protein functions. However, little is known about the global impact of LCRs on protein evolution. We have traced back the evolutionary history of 2,802 LCRs from a large set of homologous protein families from H.sapiens, M.musculus, G.gallus, D.rerio and C.intestinalis. Transcriptional factors and other regulatory functions are overrepresented in proteins containing LCRs. We have found that the gain of novel LCRs is frequently associated with repeat expansion whereas the loss of LCRs is more often due to accumulation of amino acid substitutions as opposed to deletions. This dichotomy results in net protein sequence gain over time. We have detected a significant increase in the rate of accumulation of novel LCRs in the ancestral Amniota and mammalian branches, and a reduction in the chicken branch. Alanine and/or glycine-rich LCRs are overrepresented in recently emerged LCR sets from all branches, suggesting that their expansion is better tolerated than for other LCR types. LCRs enriched in positively charged amino acids show the contrary pattern, indicating an important effect of purifying selection in their maintenance. We have performed the first large-scale study on the evolutionary dynamics of LCRs in protein families. The study has shown that the composition of an LCR is an important determinant of its evolutionary pattern.

Sobre las fronteras retóricas del español escrito

El artículo explora la presencia de elementos culturales y retóricos procedentes de la lengua nativa (L1) de un autor en sus escritos en segunda lengua (L2). Se resumen y comentan varias investigaciones de la Retórica Contrastiva, los Nuevos Estudios de Literacidad y la Traductología, que analizan las estrategias usadas por autores y traductores para ocultar o mostrar aspectos de su L1 en sus escritos en L2. También se analizan dos casos de escritura académica (de un latino que escribe en inglés y un quechua que lo hace en español), que aportan ejemplos de extralimitaciones en la corrección y de ocultación de rasgos culturales relevantes. Esos datos y las teorías permiten reflexionar sobre la gestión de la retórica y la cultura en los textos de los plurilingües, tanto desde una óptica de la construcción de la identidad como de la corrección de textos en clase.

Aprender en contexto: el uso de la geolocalización en la educación secundaria

Los profesores están sometidos a diferentes tensiones: sociales, culturales, de mercado, detendencias. Una de estas tensiones más actuales es la irrupción de la cotidianeidad tecnológi -ca dentro y fuera del aula. Son muchos los estudios que intentan visualizar los usos tecnológicospara el aprendizaje, por ejemplo, (Usos de las TIC entre los estudiantes universitarios:perspectiva académica y social de los procesos de aprendizaje mediados.

Fructose induces synthesis and reduces oxidation of liver fatty acids through ChREBP activation

Introduction and aims. During last few decades, the prevalence of obesity, metabolic syndrome and insulin resistance, among other metabolic disturbances, has raised considerably in many countries worldwide. Environmental factors (diet, physical activity), in tandem with predisposing genetic factors, may be responsible for this trend. Along with an increase in total energy consumption during recent decades, there has also been a shift in the type of nutrients, with an increased consumption of fructose, largely attributable to a greater intake of beverages containing high levels of fructose...

Cambios en los cuidadores informales en cuanto a estilos de vida, relaciones y alteraciones de salud mental

Changes in the informal caregiver life styles, relations and alterations of mental health. Justification.The increase of the population aged 65 years and older in developed countries is generating a proportional increasing of the dependency caused by chronic pathologies. The care of these persons is being carried out by relatives, informal carers, leading to some alterations in diverse areas, among them mental alterations, as a consequence of taking care. Objectives. To develop a profile of the informal carers and to correlate the caregiver burden with the carers disorders. To detect risk factors to allow carrying out premature nursing interventions to diminish the disorders in the informal carers. Design. An observational and cross-sectional study is made in primary care health services area of the city of Girona. Methodology. Random sample of carer of dependent people at their home , assigned to the program of domiciliary attention (ATDOM) of the educational basic areas of health (ABS). A sample size of 269 persons, with a level of precision of 9% was needed. Questionnaire ICUB 97, the test of Barthel, the Philadelphia Geriatric Center scale, and a questionnaire are used as instruments that includes demographic and social variables, and mental and physical carers disorders.Results. A total of 80 participants were interviewed. The most common problems as consequence of taking care were the backache, to feel more tired, to feel impotent and to have less free time. Correlation between the level of dependence of the patient with the number of problems perceived by the caretaker does not exist. Since they are informal carers they eat frequently outside the habitual schedule, took place an increase or loss of weight, experienced more disorders in sexual life and an increasing lack of interest in surroundings. A 33% of the informal carers are being treated for problems related to the mental health.Conclusion. The fact of being informal carer carries important consequences in their health, the lifestyles and the social relations. These can be attenuated if the nursing interventions are able to consider to the well-taken care of subject, and its surroundings in an holistic way. The professionals of infirmary of mental health must contribute to their knowledge and abilities contributing to make an assessment, a diagnosis and an intervention paying special attention to psycho-social aspects mentioned
