Why do I publish research articles in English instead of my own language? Differences in Spanish researchers' motivations across scientific domains

Previous studies have reported the increased use of English as the “lingua franca” for academic purposes among non-Anglophone researchers. But despite data that confirm this trend, little is known about the reasons why researchers decide to publish their results in English rather than in their first language. The aim of this study is to determine the influence of researchers’ scientific domain on their motivation to publish in English. The results are based on a large-scale survey of Spanish postdoctoral researchers at four different universities and one research centre, and reflect responses from 1717 researchers about their difficulties, motivations, attitudes and publication strategies. Researchers’ publication experiences as corresponding authors of articles in English and in their first language are strongly related to their scientific domain. But surprisingly, Spanish researchers across all domains expressed a similar degree of motivation when they write research articles in English. They perceive a strong association between this language and the desire for their research to be recognized and rewarded. Our study also shows that the target scientific audience is a key factor in understanding the choice of publication language. The implications of our findings go beyond the field of linguistics and are relevant to studies of scientific productivity and visibility, the quality and impact of research, and research assessment policies.

Determinants of success for biomedical researchers: a perception-based study in a health science research environment

New institutions are coming to the fore as stakeholders in research, particularly hospitals and clinical departments involved in providing health care. As a result, new environments for research are gaining importance. This study aims to investigate how different individual characteristics, together with collective and contextual factors, affect the activity and performance of researchers in the particular setting of hospitals and research centres affiliated with the Spanish National Health System (NHS). We used a combination of quantitative science indicators and perception-based data obtained through a survey of researchers working at NHS hospitals and research centres. Inbreeding and involvement in clinical research is the combination of factors with the greatest influence on scientific productivity, because these factors are associated with increased scientific output both overall as well as in high-impact journals. Ultimately, however, satisfaction with human resources in research group combined with gender (linked in turn to leadership) is the combination of factors associated most clearly with the most relevant indicator of productivity success, i.e. the number of articles in high-impact journals as principal author. Researchers’ competitiveness in obtaining research funding as principal investigator is associated with a combination of satisfaction with research autonomy and involvement in clinical research. Researchers’ success is not significantly related with their age, seniority and international experience. The way health care institutions manage and combine the factors likely to influence research may be critical for the development and maintenance of research-conducive environments, and ultimately for the success of research carried out in hospitals and other settings within the national public health system.

Opening doors to basic-clinical collaboration and translational research will improve researchers' performance

The present study investigate to what extent basic-clinical collaboration and involvement in translational research improve performance of researchers, in the particular setting of hospitals affiliated with the Spanish National Health System (NHS). We used a combination of quantitative science indicators and perception-based data obtained through a survey of researchers working at NHS hospitals. Although collaborating with clinical researchers and health care practitioners may increase productivity of basic researchers working in clinical settings, the extent to which they are able to contribute to translational research is the factor that allows them to make a qualitative leap in their scientific production in highly ranked international scientific journals. Our results challenge the arguments by some authors that translational projects have more difficulties than basic proposals to be granted by funding agencies and to be published in high-impact journals. Although they are not conclusive, our results point towards the existence of a positive relationship between leadership and involvement in translational research. Basic-clinical collaboration and translational research should be an incentive for researchers as they are likely to favour their performance. Hospitals will benefit from encouraging researchers and health care practitioners to collaborate in the framework of translational projects, as a way to improve not only individual, but institutional research performance. Spanish hospitals should contribute to overcome obstacles to translational research, through the full integration of basic researchers within the hospital setting and the definition of a research career path within the NHS.

On the whole, they possess a very weak antibacterial activity, a slight antifungal effect and one of them, vespertilin, displays interesting cytostatic activity (ID50 = 5 micrograms/ml). A pharmacodynamic screening carried out on this product mainly revealed very slight toxicity, antihistaminic activity and a light tranquilizing effect. The data obtained justify further research.The purpose of this study was to characterize the role of ions other than Ca2+ in hepatic responses to alpha 1-adrenergic stimulation. We report that the alpha 1-adrenoreceptor activation of hepatic functions is accompanied by extracellular acidification and an increase in intracellular pH. These effects are dependent on extracellular Na+ concentration and are inhibited by the Na+/H+ antiporter blocker 5-(N-ethyl-N-isopropyl) amiloride under conditions that preclude antagonistic effects on agonist binding. Thus, the activation of plasma membrane Na+/H+ exchange is an essential feature of the hepatic alpha-adrenoreceptor-coupled signaling pathway. The following observations indicate that the sustained hepatic alpha 1-adrenergic actions rely on a functional coupling between the plasma membrane Na+/H+ and Na+/Ca2+ exchangers, resulting in the stimulation of Ca2+ influx. 1) Inhibition of the Na+/K(+)-ATPase does not prevent the alpha 1-adrenergic effects. However, alpha 1-adrenoreceptor stimulation fails to induce intracellular alkalinization and to acidify the extracellular medium in the absence of extracellular Ca2+. 2) A non-receptor-induced increase in intracellular Na+ concentration, caused by the ionophore monensin, stimulates Ca2+ influx and increases vascular resistance. 3) Inhibition of Na+/Ca2+ exchange prevents, in a concentration-dependent manner, most of the alpha 1-agonist-induced responses. 4) The actions of Ca(2+)-mobilizing vasoactive peptide receptors or alpha 2-adrenoreceptors, which produce neither sustained extracellular acidification nor release of Ca2+, are insensitive to Na+/H+ exchange blockers.Poster presentado en la VII Reunion Anual de la Red Tematica de Investigacion Cooperativa en Cancer (RTICC), celebrada en Salamanca el 24 de septiembre de 2014Resumen del trabajo presentado al VI Meeting de la Red Espanola de Canales Ioniocs (RECI), celebrado en Santiago de Compostela del 6 al 8 de septiembre de 2017.Tesis Doctoral presentada por Laura Jimenez Perez para optar al grado de doctor por la Universidad de Valladolid, Departamento de Bioquimica y Biologia Molecular y FisiologiaPoster presentado en la VII Reunion Anual de la Red Tematica de Investigacion Cooperativa en Cancer (RTICC), celebrada en Salamanca el 24 de septiembre de 2014Resumen del trabajo presentado al XXXXVIII Congreso de la Sociedad Espanola de Bioquimica y Biologia Molecular (SEBBM), celebrado en Valencia del 7 al 10 de septiembre de 2015.Esta Tesis Doctoral fue realizada en el Centro Andaluz de Biologia del Desarrollo por la licenciada Briseida Beli Cacho Valadez para optar al grado de Doctor por la Universidad Pablo de Olavide.Rat liver S-adenosylmethionine (AdoMet) synthetase appears as high-M(r) (tetramer) and low-M(r) (dimer) forms. Both are inhibited in the presence of GSSG at pH 8. The calculated Ki values are 2.14 and 4.03 mM for the high- and low-M(r) forms, respectively. No effect on enzyme activity was observed in the presence of GSH, but modulation of inhibition by GSSG can be obtained by addition of GSH. At a total glutathione concentration (GSH + GSSG) of 10 mM, a KOX of 1.74 was calculated for the high-M(r) form, whereas this constant was 2.85 for the low-M(r) AdoMet synthetase. No incorporation of [35S]GSSG was observed in either of the enzyme forms, and inhibition of enzyme activity was correlated with dissociation of both AdoMet synthetases to a monomer. The data obtained in the presence of GSSG seem to suggest that oxidation leads to the formation of an intrasubunit disulfide. The possible regulation of AdoMet synthetase activity by the GSH/GSSG ratio is discussed, as well as its in vivo significance.Trabajo presentado en el XI Simposi de Neurobiologia: Future technical advances, organizado por la Socitat Catalana de Biologia, en Barcelona, los dias 12 y 13 de noviembre de 2018El estudio de la relacion entre componentes de la dieta y la salud/enfermedad utiliza metodos de valoracion de la ingesta dietetica, del estatus nutricional y de marcadores de funcion o de efecto. En concreto, en el estudio de los carotenoides y la salud ocular, interesa el estudio de dos carotenoides sin actividad provitamina A, la luteina y la zeaxantina, por su posible papel en la optimizacion de la funcion visual y en la prevencion de enfermedades cronicas asociadas a la edad, y de tres carotenoides con actividad provitamina A: -caroteno, -caroteno y -criptoxantina, por ser precursores de retinol, nutriente del que depende el ciclo visual para una vision normal. En el presente trabajo se ha llevado a cabo el estudio de los carotenoides de la dieta mas relevantes para la salud ocular humana considerando de forma simultanea parametros relacionados con la ingesta, el estatus y la funcion visual, asi como diversas variables que pueden modificar el estatus nutricional, como son la concentracion de lipidos en sangre, y la bioaccesibilidad de los carotenoides a partir de alimentos de amplio consumo...Fetal rat hepatocytes treated with transforming growth factor beta (TGF-beta) die by apoptosis. However, a subpopulation of them survives and undergoes an epithelial mesenchymal transition (EMT). This transition also occurs upon incubation with fetal bovine serum. We have isolated the subpopulations that undergo EMT (TGF-beta-treated-fetal hepatocytes: TbetaT-FH; serum-treated-fetal hepatocytes: ST-FH) and show that they present high levels of vimentin and Snail expression and lack cytokeratin 18 and E-cadherin. Both TbetaT-FH and ST-FH cells require mitogens to grow and maintain the response to TGF-beta in terms of growth inhibition. However, they lack differentiation markers such as the liver-enriched transcription factors hepatocyte nuclear factor 4 (HNF-4) or HNF-1alpha and express the progenitor marker OV-6. Interestingly, the EMT process confers them resistance to the apoptotic effect of TGF-beta, with cells showing higher levels of active AKT and Bcl-x(L) than fetal hepatocytes. In summary, these cells are refractory to the apoptotic effects of TGF-beta, showing characteristics of liver progenitors and of some hepatocellular carcinoma cells.Memoria de tesis presentada por Luis Vazquez Fonseca, Licenciado en Bioquimica para optar al grado de Doctor.

The bx1 allele presents unusual features when compared with other bx alleles. The phenotype of bx1 homozygotes is temperature sensitive but only with regard to the distal and not to the proximal transformation, thus suggesting two different components in the bithorax transformation. The phenotype of bx1 homozygotes is stronger than that of bx1 over the deletion of the gene, suggesting a trans interaction of the bx1 chromosomes which results in mutual partial inactivation. We show by temperature shift and clonal analysis experiments that the decision on whether to differentiate haltere or wing structures is taken at the end of the proliferation period of the mutant disc.Poster presentado al XXXVII Congreso de la Sociedad Espanola de Bioquimica y Biologia Molecular, celebrado en Granada del 9 al 12 de septiembre de 2014.Poster presentado al XXVII Congreso Nacional de la Asociacion Espanola de Genetica Humana celebrado en Madrid del 10 al 12 de abril de 2013.Poster presentado al XXXVII Congreso de la Sociedad Espanola de Bioquimica y Biologia Molecular, celebrado en Granada del 9 al 12 de septiembre de 2014.Poster presentado en el XI European Meeting on Glial Cells in Health and Disease, celebrado los dias 3 al 6 de julio de 2013 en Berlin (Alemania)Resumen del trabajo presentado al Spanish Society of Biochemistry and Molecular Biology (SEBBM), celebrado en Madrid del 16 al 19 de julio de 2019.Poster presentado en el XII European Meeting on Glial Cells in Health and Disease, celebrado los dias 15 a 18 de julio de 2015 en Bilbao (Espana)Trabajo presentado en el XL Congreso de la Sociedad Espanola de Bioquimica y Biologia Molecular.

This behavior allows the preparation of nucleosomal particles containing only one H2A.H2B dimer, which were complemented with 125I-labeled H2A.H2B. These reconstituted particles, which contain one labeled and one unlabeled H2A.H2B dimer, were treated with the amount of reagent needed to release one of the two H2A.H2B dimers. Radioactivity was equally distributed between residual particles and released proteins, which is consistent with equivalent binding sites in the nucleosomal particle for H2A.H2B dimers, rather than with intrinsically different sites. The asymmetric release of H2A.H2B dimers would be caused by a change in the binding site of one dimer following the release of the other. This behavior might be related to the structural dynamics of nucleosomes.Resumen del trabajo presentado al European Society of Cardiology (ESC) Congress, celebrado en Barcelona (Espana) del 26 al 30 de agosto de 2017.Resumen del poster presentado al 49th European Association for the Study of Diabetes Annual Meeting, celebrado en Barcelona (Espana) del 23 al 27 de septiembre de 2013.-- et al.Trabajo doctoral realizado por Da Rebeca Lapresa Ruiz de Gauna, para optar al grado de doctor por la Universidad de Salamanca.Rationale: Several animal models have been developed to study acute lung injury (ALI); however the majority of these studies are focused on different mechanisms within the acute phase. These models do not allow studying the mechanisms in the later phases or testing any possible long-term treatment. The aim of this study was to develop an experimental ALI model simulating bronchial aspiration of gastric contents with bacterial superinfection with alveolar epithelial damage persisting over time. Methods: Sprague-Dawley rats (200-250g) were anesthetized with isofluorane. ALI was induced by intratracheal instillation of HCl (1 µl/g, 0.1 mol/L pH=1.4) followed by instillation of LPS from Escherichia coli O55:B5 (0, 10, 20, 30 or 40µg/g b.w.) two hours later. Control rats were treated with intratracheal instillations of saline. After 72h, the animals were sacrificed and bronchoalveolar lavage fluid (BALF) was sampled for further analysis of total protein concentration by bicinchoninic acid method. Results: At 72 h, rats suffered a significant loss of weight proportional to the administered dose of LPS (5.6% with 10µg/g b.w, 12.6% with 20µg/g b.w, 14.2% with 30µg/g b.w and 17.7% with 40µg/g b.w). Control rats gained in weight at 72h. LPS at 10, 20, 30 and 40µg/g b.w induced a 1.7, 2.5, 2.9 and 3.4 fold increase in total protein concentration in BAL fluid, respectively, reflecting a substantial increase proportional to the LPS dose. Conclusion: The degree of weight loss and the increase of total protein concentration in BAL fluid in the current model may reflect disease severity and progression. This model would be useful in future for new therapeutical options.
