Abstract Background: John Cunningham virus (JCV) constitutes a family of polyoma viruses, which plays important roles in the progressive multifocal leukoencephalopathy (PML) and tumorigenesis. However, no bibliometric investigation has been reported to guide the researchers and potential readers. Methods: Papers were collected from database Sci-expanded and Pubmed until May 22, 2008. The highly-productive authors, institutes and countries, highly-cited authors and journals were ranked. The highly-cited articles were subjected to co-citation and chronological analysis with highly- frequent MeSH words for co-occurrence analysis. Results: Until now, 1785 articles about JCV were indexed in Sci-expanded and 1506 in Pubmed. The main document type was original article. USA, Japan and Italy were the largest three producers about JCV. Temple University published 128 papers and ranked the top, followed by University of Tokyo. Khalili K and Yogo Y became the core authors due to more than 20 documents produced. Journal of Neurovirology published more than 15 papers and ranked the top. Padgett BL and Berger JR were the first two highly-cited authors. Journal of Virology and Journal of Neurovirology respectively ranked to the first two highly-cited journals. These top highly-cited articles were divided into 5 aspects: (1) The correlation between JC virus and tumors; (2) Causal correlation of JCV with PML; (3) Polyoma virus infection and its related diseases in renal-allograft recipients; (4) Detection of JCV antibody, oncogene and its encoding protein; (5) Genetics and molecular biology of JCV. The MeSH/subheadings were classified into five groups: (1) JCV and virus infectious diseases; (2) JCV pathogenicity and pathological appearance of PML; (3) JCV isolation and detection; (4) Immunology of JCV and PML; (5) JCV genetics and tumors. Conclusion: JCV investigation mainly focused on its isolation and detection, as well as its correlation with PML and tumors. Establishment of transgenic animal model using JCV T antigen would be a hopeful and useful project in the further study.

For this reason, the objective of this study was to evaluate Colombian publications on viruses and viral diseases in indexed journals during the period from 2000 to 2013. Methodology: The bibliographic data were collected from MedLine, SciELO, LILACS and Scopus databases. The database was constructed in Excel descriptive statistics. The SCImago Journal Rank (SJR) was evaluated using the SCImago Journal & Country Rank in 2013 and was used as an indicator of the quality of the journals used by the Colombian researchers. Results: The total number of papers published was 711, of which 40.4% were published in local journals, and 59.6% were published in foreign journals. Most (89.2%) were original papers. Moreover, 34.2% of the papers were published in collaboration with international researchers, with the United States being the most represented. Of the journals used, 85.6% had an SJR, and 14.4% did not. The median SJR of the papers was 0.789, and the median of the papers with international collaborators was higher compared to the SJR of the papers without international collaboration.

Zyoud1,2 Abstract Background: Middle East respiratory syndrome coronavirus (MERS-CoV) is a virus that causes severe viral pneumonia in humans, known to have a high mortality rate and a similarity in clinical symptoms with severe acute respiratory syndrome coronavirus. It was first isolated in Kingdom of Saudi Arabia (KSA) in 2012 and after that, MERS-CoV exhibited outbreaks in several regions of the world. This study aimed to assess the characteristics of publications involving MERS-CoV at global level by using a bibliometric analysis. Methods: Scopus database was searched on March 4, 2016 for MERS-CoV publications published between 2012 and 2015. It was performed on the same day in order to avoid the possible bias came from update on the database because the metrics are changing over time. All publication types were considered; however publications as errata were excluded. Analysis parameters include year of publication, publication type, patterns of international collaboration, research institutions, journals, impact factor, h-index, language, and times cited. Results: A total of 883 MERS-CoV research publications were published across the world. The MERS-CoV-associated publications were originated from 92 countries/territories, indicating the international spread of MERS-CoV research. The USA was the largest contributor, with 319 articles published over 4 years, followed by KSA (113 articles). The total number of citations for these publications has already achieved 8,015, with an average of 9.01 citations per each publication.

Abstract During the current century, each major coronavirus outbreak has triggered a quick and immediate surge of academic publications on this topic. The spike in research publications following the 2019 Novel Coronavirus (Covid-19) outbreak, however, has been like no other. The global crisis caused by the Covid-19 pandemic has mobilised scientific efforts in an unprecedented way. In less than five months, more than 12,000 research items have been indexed while the number increasing every day. With the crisis affecting all aspects of life, research on Covid-19 seems to have become a focal point of interest across many academic disciplines. Here, scientometric aspects of the Covid-19 literature are analysed and contrasted with those of the two previous major Coronavirus diseases, i.e. Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS).

See Immigration and Nationality Act (the Act) section 203(b)(l)(A), 8 U.S .C. § 1153(b)(l)(A). This first preference classification makes immigrant visas available to those who can demonstrate their extraordinary ability through sustained national or international acclaim and whose achievements have been recognized in their field through extensive documentation. The Director of the Nebraska Service Center denied the petition, concluding that the record did not establish, as required, that the Petitioner meets at least three of the ten initial evidentiary criteria for this classification. The matter is now before us on appeal. In these proceedings, it is the Petitioner's burden to establish eligibility for the requested benefit by a preponderance of the evidence. See Section 291 of the Act, 8 U.S.C. § 1361; Matter ofChawathe, 25 l&N Dec. 369, 375 (AAO 2010). Upon de nova review, we will dismiss the appeal. I.

    [Downloaded free from http://www.jfcmonline.com on Monday, February 8, 2021, IP: 217.52.7.41] Review Article Access this article online Quick Response Code: Bibliometric analysis of coronavirus disease (COVID-19) literature published in Web of Science 2019–2020 Rai K. Farooq, Shafiq Ur Rehman1, Murtaza Ashiq2, Nadeem Siddique3, 1 Website: Shakil Ahmad www.jfcmonline.com DOI: 10.4103/jfcm.JFCM_332_20 Abstract: Coronavirus outbreak in Wuhan, China, turned into a pandemic in record time. Communication of disease presentation and mechanism of spread remain keys to getting ahead of the virus and limiting its spread beyond the capacity of management. Owing to huge academic focus and pandemic concern around the globe, this bibliometric analysis investigated research productivity related to coronavirus disease (COVID-19) pandemic using the Web of Science database. The relevant data were harvested, and search query was further refined by publication years (2020 OR 2019) and document types (article, book chapter, and proceedings paper). Finally, 6694 records were imported and downloaded in Plaintext and BibTeX formats on August 1, 2020. The data analysis was performed using MS Excel, VOS viewer, and Biblioshiny software. Of the 6694 publications that appeared in that period, the USA and Chinese research institutions topped the numbers. At the same time, the Journal of Medical Virology and CUREUS (Cureus Journal of Medical Science), remained favorite journals for publications. The pattern of multi-author publications has outstripped that of single-authors. Apart from COVID-19 and the novel coronavirus, the important keywords mentioned included pandemic, pneumonia, epidemiology, public health, outbreak, epidemic, China, infection, and treatment.
