Abstract

On the 6th December 2008, in my role as Editor-in-Chief of the International Journal of Cardiology, I received an email from Professor Harold Garner of UT Southwestern Medical Center, Dallas. Professor Garner told me that using a new search engine methodology (eTBLAST) he and colleagues had identified a paper in the International Journal of Cardiology published in 1996 which had remarkable text and data similarity to an earlier paper published in 1992 in the New England Journal of Medicine. They had detected this similarity after randomly selecting citations from Medline and submitting them to the tool to find other highly similar citations as part of their NIH/R01 funded research on the ethics of publication. We have been notified that all such cases are reported in a database, Déjà Vu (http://spore.swmed.edu/dejavu/). We investigated the text of the two papers and we agreed that there was such a similarity that the later paper must have plagiarized the earlier paper, and in doing so infringed the copyright. In accordance with our previously published standards on ethical publishing in the Journal we hereby retract the paper “The prognostic value of serum troponin T in unstable angina. Gökhan Cin V, Gök H, Kaptanoğlu B. Int J Cardiol. 1996 Mar;53(3):237–44.”.

On the 6th December 2008, in my role as Editor-in-Chief of the International Journal of Cardiology, I received an email from Professor Harold Garner of UT Southwestern Medical Center, Dallas. Professor Garner told me that using a new search engine methodology (eTBLAST) he and colleagues had identified a paper in the International Journal of Cardiology published in 1996 [1] V. Gökhan Cin, H. Gök and B. Kaptanoğlu, The prognostic value of serum troponin T in unstable angina, Int J Cardiol 53 (3) (Mar 1996), pp. 237–244.[1] which had remarkable text and data similarity to an earlier paper published in 1992 in the New England Journal of Medicine [2]. They had detected this similarity after randomly selecting citations from Medline and submitting them to the tool to find other highly similar citations as part of their NIH/R01 funded research on the ethics of publication. We have been notified that all such cases are reported in a database, Déjà Vu(http://spore.swmed.edu/dejavu/). We investigated the text of the two papers and we agreed that there was such a similarity that the later paper must have plagiarized the earlier paper, and in doing so infringed the copyright. In accordance with our previously published standards on ethical publishing in the Journal [3] we hereby retract the later paper. We reiterate our policy of zero-tolerance of such scientific fraud. Unfortunately the retracted paper had been published in 1996 before the present editorial team had been appointed and we do not have the source material relating to its original submission, and the editor-in-chief of the time has unfortunately died. The authors of the retracted papers have published nothing else in the International Journal of Cardiology, but a review of Pubmed shows that the first author has published one other paper in 2004, a case report in Circulation Journal, and the second and third authors many other papers in recent years. The publication of papers containing scientific fraud and plagiarized material is unfortunately not uncommon and we all have a duty to ensure this fraud is detected and reported to assist in deterring future occurrences.

This article has been retracted at the request of the Editor-in-Chief. Please see Elsevier Policy on Article Withdrawal
Reason: The Editors of International Journal of Adhesion and Adhesives have noticed that two nearly identical papers, authored by Dr Zeynep Duymus Yesil and co-workers, have been published in the journal. These are: Evaluation of the bond strength of different composite resins to porcelain and metal alloy,Int. J. Adhes. Adhes., 27 (2007) 258–262 by Zeynep Duymus Yesil, Serpil Karaoglanoglu, M. Samil Akyil, Nilgun Seven, and the present paper.
The present article has been  retracted at the request of the Editors as it is essentially a duplicate of the 2007 paper that has already been published. One of the conditions of submission of a paper for publication is that authors declare explicitly that the paper is not under consideration for publication elsewhere. As such, the 2009 article represents a breach of this condition. We apologize to the readers of the journal that this was not detected during the submission process.

One of the conditions of submission of a paper for publication is that authors declare explicitly that all portions of their work are original and have not appeared in a publication elsewhere. Re-use of any text, figures, or data should be appropriately cited. Since this article quoted sections of prior work without appropriate acknowledgment, it violates scientific publishing system protocol. The scientific community takes a very strong view on this matter and we apologize to readers of the journal that this was not detected during the submission process.
