COLUMBIA, Mo. (AP) — The University of Missouri has been investigating claims that two researchers from its medical school plagiarized a journal article that has since been retracted.

The American Journal of the Medical Sciences retracted the February 2012 article last week after determining that two authors from the university's medical school, fourth-year postdoctoral student Amar Jadhav and clinical assistant cardiology professor Anand Chockalingam, "plagiarized significant aspects" of a 2006 article published in the journal Heart, The Columbia Missourian reported Tuesday ( ).

The University of Missouri researchers' article was entitled "Ventricular Ectopic Beats: An Overview of Management Considerations" and also had a third author affiliated with a medical school in India. Neither of the University of Missouri co-authors replied to Associated Press requests for interviews.

University spokesman Christian Basi said officials there found out about the allegations July 2. He said the university assigned the investigation to an inquiry committee on Aug. 3 and that the delay in starting the investigation was due to summer absences.

The Missouri researchers could face sanctions including termination if they're found to have plagiarized.

G. André Ng, author of the 2006 article contacted the editor of Heart when he noticed the Missouri researchers' work was similar to his. The Heart editor then informed British Medical Journal Group, which publishes Heart.

BMJ spokeswoman Caroline White said the articles were compared using plagiarism detection software and the result was a "very high percentage similarity rating."

White said that after an expert review of the two papers, the medical sciences journal agreed its article had plagiarized the Heart article. The American Journal of the Medical Sciences then issued its retraction.
