Scientific profiles in the field of biomarkers (2000-2010)

Abstract

Biological marker is a term used in many scientific fields and was introduced as a measurable element or a clinical indicator in the abnormal biological processes, pathological condition, or pharmacological intervention. Science Citation Index Expanded (SCI-E) from database of Web of Science (WoS) was used to extract all publication indexed as a topic of "Biomarkers" during a period of eleven years through 2000-2010. Extracting of data was restricted to the tag of topics (TS = Biomarkers) from advanced search menu. A total number of 37397 records were extracted on 5 May 2013 and went under analysis. In this study the papers originated jointly by multiple authors from different countries were defined as ones for each country. The study showed that the number of publication in the field of biomarkers showed an increase through the period of study. The number of publication in 2010 was greater than 10 times in 2000. More than 98% of publication was in English. The majority of publication (68%) was in the form journal article. Harvard University, sharing 1,128 papers in the field, was the most prolific university among institutes. The USA contributing 33% of world's profile in the field was the most productive country. Based on the Bradford's scattering law, the journal of "Cancer Epidemiology Biomarkers Prevention" publishing 3.12% of world's publication was the most prolific journal among core journals. Analysis of data concluded that oncology was the most interesting subject area of scientists in the field of Biomarkers through the last decade.
