The top cited articles on glioma stem cells in Web of Science

BACKGROUND: Glioma is the most common intracranial tumor and has a poor patient prognosis. The presence of brain tumor stem cells was gradually being understood and recognized, which might be beneficial for the treatment of glioma. OBJECTIVE: To use bibliometric indexes to track study focuses on glioma stem cell, and to investigate the relationships among geographic origin, impact factors, and highly cited articles indexed in Web of Science. METHODS: A list of citation classics for glioma stem cells was generated by searching the database of Web of Science-Expanded using the terms "glioma stem cell" or "glioma, stem cell’" or "brain tumor stem cell". The top 63 cited research articles which were cited more than 100 times were retrieved by reading the abstract or full text if needed. Each eligible article was reviewed for basic information on subject categories, country of origin, journals, authors, and source of journals. Inclusive criteria: (1) articles in the field of glioma stem cells which was cited more than 100 times; (2) fundamental research on humans or animals, clinical trials and case reports; (3) research article; (4) year of publication: 1899-2012; and (5) citation database: Science Citation Index-Expanded. Exclusive criteria: (1) articles needing to be manually searched or accessed only by telephone; (2) unpublished articles; and (3) reviews, conference proceedings, as well as corrected papers. RESULTS: Of 2 040 articles published, the 63 top-cited articles were published between 1992 and 2010. The number of citations ranged from 100 to 1 754, with a mean of 280 citations per article. These citation classics came from nineteen countries, of which 46 articles came from the United States. Duke University and University of California, San Francisco led the list of classics with seven papers each. The 63 top-cited articles were published in 28 journals, predominantly Cancer Research and Cancer Cell, followed by Cell Stem Cell and Nature. CONCLUSION: Our bibliometric analysis provides a historical perspective on the progress of glioma stem cell research. Articles originating from outstanding institutions of the United States and published in high-impact journals are most likely to be cited.

Where Does Research Occur in Geriatrics and Gerontology?

The International Plan of Action on Aging 2002 emphasized the need to promote and develop research on aging, especially in underdeveloped countries. This article aims at describing the current situation with regard to the international scientific production in the field of geriatrics and gerontology. All articles published in journals included in the categories "Geriatrics and Gerontology" of the Science Citation Index or "Gerontology" of the Social Science Citation Index in 2002 were analyzed. There is unquestionable predomination by the United States, which participates in 53.8% of the articles analyzed, followed by the United Kingdom (9.66%) and Canada (6.66%). The production of the 15 European Union countries together is 31.2%. When adjustments are made for economic or population factors, other countries show their importance: Israel and Sweden, for example. Authors from richer countries participate in more than 95% of the articles, whereas those in less-developed countries tend to publish less, and when they do so, it is through collaboration with more-developed countries. In general, only 10.5% of the articles are written in collaboration with institutions from different countries. One of the keys to stimulating research in less wealthy countries would seem to be precisely through collaboration. This would aid the transfer of knowledge and experience, allowing researchers in these countries to obtain autonomy to perform their own studies independently and to provide them with the ability to gain access for their publications at the international level.

Bibliometrics Study on Authorship Trends in Periodontal Literature From 1995 to 2010

Background: Biomedical research has grown considerably in the last few decades, and the authorship characteristics of the dental literature as a whole and of its specialty fields has changed significantly. Unfortunately, the bibliometrics of the periodontal literature have not been thoroughly investigated. The aim of this study is to investigate the bibliometrics of periodontal literature, assessing the geographic origin, study design, and topics investigated in periodontal research published from 1995 to 2010. Methods: Articles published in periodontal journals during 1995 to 2010 were retrieved through hand search. Inclusion/exclusion criteria were applied. The following variables were extrapolated from each article: number of authors, study design, topic investigated, financial support, and geographic origin. The general linear model assessed the influence of independent variables on number of authors per article, and χ² test assessed the statistical difference of the variables over years 1995 to 2010. Results: A total of 2,260 articles were reviewed; 2,076 met the inclusion criteria. The number of authors per article increased (P <0.001) from 4.0 (1995) to 5.1 (2010). The proportion of articles published from North America and Europe decreased (P <0.001) from 84.3% (1995) to 58.6% (2010), whereas for Asia and South America the article proportion increased (P <0.001) from 13.8% (1995) to 40% (2010). Research targeting prevention and treatment of periodontal disease is decreasing (P <0.001) in favor of implant‐related research. Governmental research funding is increasing (P <0.001). Conclusion: Periodontal research significantly changed during the last 15 years.
