Productivity of CNPq Researchers from Different Fields in Biomedical Sciences: The Need for Objective Bibliometric Parameters-A Report from Brazil

Empenho dos bolsistas de pós-doutorado júnior na área de Ciências Biológicas no Brasil: uma análise bibliométrica

Resumo Muito se tem falado sobre a importância dos indicadores científicos no processo de crescimento e desenvolvimento dos países. Nesse cenário, o presente trabalho buscou analisar o empenho dos bolsistas de pós-doutorado júnior em algumas áreas de Ciências Biológicas (botânica, bioquímica, farmacologia e ecologia) no Brasil. Esta pesquisa classificou-se como descritiva quanto ao seu objetivo e fez uso da bibliometria para analisar os dados encontrados. O desempenho de 97 bolsistas de pós-doutorado júnior com bolsa vigente no site do Conselho Nacional de Desenvolvimento Científico e Tecnológico, foi analisado através do banco de dados Scopus. Os resultados obtidos demonstram que São Paulo é o estado brasileiro que apresenta o maior número de bolsistas (cerca de 20,62%), sendo a Universidade de São Paulo a instituição com a maior predominância de pós-doutorandos (12,37%). A botânica apresenta papel de destaque como área de atuação no campo das Ciências Biológicas, com o maior número de artigos indexados na base Scopus, apresentando uma média de 10,63 artigos por pesquisador. A área de Ecologia apresenta a maior média anual de publicações, com uma média de 1,56 publicações por ano. Observa-se que o pós-doutorado júnior é uma experiência que pode proporcionar avanço do conhecimento e capacitação científica e tecnológica visando à aplicação dos resultados em diversos setores sociais.

Trends in general and public health scientific output of authors affiliated to Brazilian institutions among high-impact and SciELO journals: 1995-2019

This study aimed to assess the percentage of articles with authors affiliated to Brazilian institutions in high-impact journals and SciELO journals and to evaluate trends in 5-year citations according to the author's affiliation and journal category. Bibliometric data were obtained using Scopus database from 1995 to 2019. Publications were selected from four journal categories: High-impact General Health (HGH), High-impact Public Health (HPH), SciELO General Health (SGH) and SciELO Public Health (SPH). The number of citations that were received five years after publication and the percentage of publications with any author affiliated to Brazil were calculated by each year. The same 146 journals were followed. There was a significant increase in percentage of articles with authors affiliated to Brazilian institutions in all sets of journals. Among HGH, there was an increasing from 0.3% to 1.5% between 1995-2019, for HPH from 1% to 3%, for SGH from 49.7% to 55.4%, and for SPH from 47.4% to 71.9%. There was a significant (p < 0.01) increase in the mean of 5-year citations in all groups and Brazilian affiliated articles increased more than average. For each 10 years, average HGH articles increased 11.9 citations and Brazilian affiliated articles 32.0 citations. The results suggest that the presence of Brazilian science is increasing, and the scientific impact has increased more than average.

Bibliometric analysis of personalized humanized mouse and Drosophila models for effective combinational therapy in cancer patients

Research performed using model organisms such as mice and the fruit fly, Drosophila melanogaster has significantly enhanced our knowledge about cancer biology and the fundamental processes of cancer. This is because the major biological properties and genes associated with cancer including signaling pathways, oncogenes, tumor suppressors, and other regulators of cell growth and proliferation are evolutionary conserved. This review provides bibliometric analysis of research productivity, and performance of authors, institutions, countries, and journals associated with personalized animal cancer models, focussing on the role of Drosophila in cancer research, thus highlighting emerging trends in the field. A total of 1469 and 2672 original articles and reviews for Drosophila cancer model and patient-derived xenograft (PDX) respectively, were retrieved from the Scopus database and the most cited papers were thoroughly analyzed. Our analysis indicates a steadily increasing productivity of the animal models and especially of mouse models in cancer research. In addition to the many different systems that address almost all aspects of tumor research in humanized animal models, a trend towards using tailored screening platforms with Drosophila models in particular will become widespread in the future. Having Drosophila models that recapitulate major genetic aspects of a given tumor will enable the development and validation of novel therapeutic strategies for specific cancers, and provide a platform for screening small molecule inhibitors and other anti-tumor compounds. The combination of Drosophila cancer models and mouse PDX models particularly is highly promising and should be one of the major research strategies the future.

Research trends in food chemistry: A bibliometric review of its 40 years anniversary (1976-2016)

This study presents a general bibliometric overview of the major scientific developments that have been published in Food Chemistry, since its first issue (1976). The bibliometric data were retrieved from the scopus database. The review identifies the most cited, productive authors, and the leading institutions and countries of the journal, based on bibliometric indicators. The research hot spots in the period from 1976 to 2016 were identified by using the visualization of similarities software (Vosviewer), and the graphical mapping of the authors was developed to visualize networks between authors. A total of 20,050 publications was analysed and the most influential subjects covered by the journal were identified. Topics related to the antioxidant components of foods and the analytical quantification of contaminants or components of food were identified as being most relevant.The bibliometric analyses indicate a significant evolution of the journal in terms of publications, scientometric performance and themes covered.
