Abstract The status of any journal in which research is published is an important issue for academics. For many years the impact factor has been the criteria of choice to infer the quality of the research being published by each journal. However, with the massification of the internet, research currently impacts well beyond the academic community. This study aims to introduce readers into other bibliometric and non-bibliometric (altmetric) indicators that provide a wider perspective about the impact any particular research outcome may have besides citations. From a geographic viewpoint, the documents published by AJVS between 2010-2019 were written by authors affiliated to institutions from 33 different countries, mostly from Chile (37%) and Mexico (24%). These two countries served as collaboration nodes for countries from America, Asia, Europe and Oceania. From an altmetric perspective, 59 documents published between 2010-2016 were mentioned at least once in one of the sources tracked, being the majority of them through social media. Of particular interest is one document that was used as a reference for a patent issued in 2017 by researchers that were not related to the document published in the journal. Unfortunately, data for the documents published between 2017-2019 were unavailable, probably due to issues with the journal title change. Nevertheless, it is fair to conclude that since research outputs have shown to have an impact well beyond academia, it may be time to reconsider how journals should be assessed in the near future.

SUMMARY: Plants are exposed to several types of abiotic stress that affect their development. Among these, salinity and drought affect large areas of land worldwide. Chile does not escape this reality, estimating that 49.1 % of the territory have these characteristics. Due to the boom of forestry in Chile, the development of strategies aimed at using these low-quality soils becomes imperative. In this context, understanding the mechanisms involved in salt and drought stress in tree species such as Eucalyptus grandis has become essential. Thus, the permeability of the cell membrane was established by electrolyte leakage, recognizing that the plants exhibit damage after 12 hours of salt stress and after 10 hours of drought stress. Furthermore, the expression of a specific gene (NHX1) was determined on Eucalyptus grandis plants subjected to salt and water stress, establishing a rise in its expression in foliar and root tissue. From a physiological perspective, the observed response to abiotic stress is similar to that described for other plant species that have a shorter life cycle. Additionally, the increased expression of a specific gene (NHX) under conditions of abiotic stress confirms it as a potential candidate for genetic improvement programs in woody species for the selection of individuals tolerant to these types of stress.

RESUMEN: Las plantas se encuentran expuestas a diferentes condiciones de estrés abiótico que perjudican su desarrollo. Entre estos destacan la salinidad y la sequía, dado que afectan grandes extensiones de terrenos alrededor del mundo. Chile no escapa a esta realidad, estimándose que el 49,1 % del territorio posee estas características. Con el auge de la industria forestal del país, se torna necesario desarrollar estrategias para aprovechar suelos de menor calidad. En este sentido, es fundamental la compresión de los mecanismos que participan en la tolerancia a salinidad y sequía en especies forestales como Eucalyptus grandis. Con este propósito se determinó la permeabilidad de la membrana celular a través de ensayos de fuga electrolítica, estableciéndose que las plantas exhiben daño después de 12 horas de exposición a estrés salino y después de 10 horas de exposición a estrés osmótico. Asimismo, se cuantificó la expresión génica de un gen especifico (NHX) bajo Condiciones de estrés salino e hídrico en plantas jóvenes de E. grandis, registrándose un incremento de su expresión tanto en tejido radicular como en tejido foliar. Desde una perspectiva fisiológica, la respuesta a estrés abiótico observada es similar a la descrita para otras especies vegetales que poseen un ciclo de vida más corto. Adicionalmente, el aumento de la expresión del gen NHX bajo condiciones de estrés abiótico lo confirma como un potencial candidato para programas de mejoramiento genético para seleccionar especies leñosas tolerantes a estos tipos de estrés.

Resumo O objetivo deste estudo foi investigar a associação entre a escolha do idioma e o número de citações, a partir da análise de revistas publicadas em inglês e em outras línguas. Foram selecionadas as revistas agrupadas no Journal Citation Reports de 2014 sob a categoria “ciências veterinárias”, bem como os dados registrados na Web of Science entre 1994 e 2013 sobre as revistas que declararam documentos publicados em outro idioma que não o inglês. A seguir, as revistas foram classificadas por quartil, extraindo-se informações acerca de: índice de impacto, idioma(s) declarado(s), país de origem, número total de documentos publicados, número total de revisões publicadas, porcentagem de documentos publicados em inglês e quartil em que cada jornal foi classificado. Dos 48.118 documentos editados por 28 revistas analisadas, 55,8% foram publicados em inglês. Interessantemente, apesar de a maioria dessas revistas se declarar multilíngue, a maior parte dos documentos publicados em revistas quartil 1 empregou o inglês (uma média de 99,2%), enquanto para as revistas quartil 2 esse índice foi de 93,1%, para quartil 3 foi de 62,1%, e para quartil 4 foi de 27,4%. A pesquisa também confirmou que a distribuição das citações nessas revistas foi altamente distorcida. Os resultados do estudo sugerem que as revistas deveriam adotar o inglês como idioma principal, o que faz aumentar o número de citações e o fator de impacto da revista.

Abstract The purpose of this study was to investigate the association between language and total number of citations found among documents in journals written in English and other languages. We selected all the journals clustered together in the Journal Citation Reports 2014 under the subject category “Veterinary Sciences” and downloaded all the data registered between 1994-2013 by Web of Science for the journals that stated publishing documents in languages other than English. We classified each of these journals by quartile and extracted information regarding their impact factor, language(s) stated, country of origin, total number of documents published, total number of reviews published, percentage of documents published in English and the quartile in which each journal ranked. Of the 48,118 documents published by the 28 journals analyzed, 55.8% were published in English. Interestingly, although most of the journals state being multi-language, most documents published in quartile 1 journals were in English (an average of 99.2%), while the percentage was 93.1% in quartile 2 journals, 62.1% in quartile 3 journals and 27.4% in quartile 4 journals. We also confirmed that citation distribution in these journals was highly skewed. The results of this study suggest that journals should consider adopting English as the main language as this will increase citation counts and the impact factor of the journal.

In January 2007, the Chilean Journal of Agricultural Research was indexed by the Institute of Scientific Information (ISI). This paper reviews the research that has been published since 2007 by using records extracted from the Web of Science database. The papers published were mostly affiliated to researchers from Chile, and six out of the ten most-contributing countries were from Latin America. The analysis by institutions showed Universidad de Concepcion as the most prolific, although this result is not valid. A lack of standardization in the manner the Instituto de Investigaciones Agropecuarias (INIA) subscribed its address on each paper caused a disaggregation of the information. This was proven by the manual curation of each record that was affiliated to any of the centers belonging to INIA. The journal has a self-citation rate of 19.3%, value that is relatively high if compared to other journals from the same subject category listed on The Journal Citation Reports 2010. Finally, this work should be considered a bibliometric snapshot of the current situation of the journal that will serve as a benchmark when new evaluations are made in a few-years time.

En enero 2007, la revista Chilean Journal of Agricultural Research fue indexada por el Institute of Scientific Information (ISI), por lo que este artículo analiza la investigación que ha sido publicada desde el año 2007 utilizando los registros extraídos de la base de datos Web of Science. Los artículos publicados fueron mayormente afiliados a investigadores de Chile, siendo seis de los 10 países que más contribuyeron en artículos de Latinoamérica. Un análisis por institución mostró a la Universidad de Concepción como la más prolífica, aunque este resultado no es válido por una ausencia de estandarización en la manera que el Instituto de Investigaciones Agropecuarias (INIA) suscribe su dirección en cada artículo, lo que provoca disgregación de la información. Esto se verificó mediante la curación manual de cada registro que se encontraba afiliado a cualquiera de los centros que pertenecen a INIA. Esta revista tiene un grado de auto-citas de 19.3%, valor relativamente alto si se compara con revistas de la misma categoría de tópico que se encuentran listadas en Journal Citation Report 2010. Finalmente, este trabajo debe ser considerado como una visión bibliométrica de la situación actual de la revista que servirá como línea base para nuevas evaluaciones a realizarse en pocos años más.

Background: During the last decade Revista Médica de Chile increased its visibility, measured on citations and impact factor. Aim: To perform a scientometric analysis to assess the performance of Revista Médica de Chile. Material and methods: Thomson's-ISI Web of Science and Journal Citation Reports QCR) were consulted for performance indicators of Revista Médica de Chile and Latin Amerícan journals whose subject is General and Internal Medicine. We also report the h-index of the journal, which infers quality ¡inked to the quantity of the output. Results: According to the h-index, Revista Médica de Chile ranks 4 among the 36 journals indexed and published by Argentina, Brazil, Chile and México. The top ten articles published by Revista Médica de Chile and the institutions with the higher contríbution to the journal, were identified using citations. In the Latin Amerícan región, Brazil relevantly increased its scientific output. However, Argentina, Chile and México maintain a plateau during the last decade. Conclusions: Revista Médica de Chile increased notoriously its performance. Its contríbution to the Chilean scientific community dedicated to Medicine appears to be of central value.

Eucalyptus globulus is the most important commercial temperate hardwood in the world because of its wood properties and due to its characteristics for biofuel production. However, only a very low number of expressed sequence tags (ESTs) are publicly available for this tree species. We constructed a cDNA from E. globulus seedlings subjected to low temperature and sequenced 9,913 randomly selected clones, generating 8,737 curated ESTs. The assembly produced 1,062 contigs and 3,879 singletons forming a Eucalyptus unigene set. Based on BLASTX analysis, 89.3% of the contigs and 88.5% of the singletons had significant similarity to known genes in the non-redundant database of GenBank. The Eucalyptus unigene set generated is a valuable public resource that provides an initial model for genes and regulatory pathways involved in cell wall biosynthesis at low temperature.

The purpose of this study was to carry out a bibliometric analysis of the articles published in Chile during 1987-2006 that were categorized into the Plant Science discipline by ISI. The data was extracted from the Web of Science datábase, obtaining a total of 911 articles for analysis. Almost half of the articles were the outcome of an international collaboration, the United States being the country with more collaborative links with Chile within this discipline. A list was made with the 10 most-cited articles and 10 most frequently used journals. The analysis showed that almost 50% of the articles were concentrated in 10 different journals. The number of articles produced each year revealed a steady growth in scientific production since 1987. This is probably related to the progressive interaction between industry and public-research institutions.

The seasonal adaptation of the teleost Cyprinus carpio to the cyclical changes of its habitat demands physiological compensatory responses. The process involves profound nucleolar adjustments and remarkable changes in rRNA synthesis, which affects ribosomal biosynthesis. In this context, we have demonstrated that the synthesis of several proteins involved in ribosomal biogenesis as protein kinase CK2, ribosomal protein L41 and nucleolin, as well as U3 snoRNP, are differentially regulated in summer-acclimatized carp compared to the cold-season adapted fish. To understand the mechanisms involved in the seasonal regulation of rRNA gene transcription, we have been studying the carp rDNA cistron structure. Because the cis-elements that regulate the expression of the tandem organized ribosomal genes are located in the non-transcribed intergenic spacer (IGS), we analyzed the primary structure of the carp rDNA gene IGS. The gene organization is similar to that described from other vertebrate species, including numerous repetitive sequences, the transcription start site, and some potential cis-elements such as ribosomal enhancers, proximal terminator and transcriptional terminators. Ribosomal DNA is a remarkable case of gene duplication and has been used as a model to test the concerted evolution theory. We performed sequence comparison analyses of 18S rRNA coding sequences from carp with different species, data with which an unrooted phylogram was constructed.
