Only days after his paper was published online, a neuroscientist has posted a comment on PubMed alerting readers to several duplication errors.
Despite the issues, which the researcher says were introduced into the final manuscript after peer review, he reassured readers that they do not influence the final conclusions in the paper.
On February 9, ten days after the article came online, corresponding author Garret Stuber at the University of North Carolina at Chapel Hill wrote a detailed comment on PubMed Commons, explaining that the “research community” had brought four figure-related errors to his attention. After investigating the concerns, Stuber discovered that the problems emerged after the peer-review process, “while revising the manuscript to comply with Nature Neuroscience’s final formatting guidelines.” In his note, he outlined the specific duplication issues that arose, which he says he plans to detail to the journal in a formal corrigendum letter.
A cancer biologist based at the University of Maryland is transitioning out of research, as a journal has retracted three more of his papers.
Anil Jaiswal has now lost 13 papers, including, as we reported on February 6, six retractions issued earlier this month.
The Baltimore Sun reported this week that Jaiswal would no longer be conducting research at the University of Maryland School of Medicine, which we confirmed from a spokesperson:
The notices keep coming for diabetes researcher Mario Saad.
Diabetes has just retracted two more of his papers, both of which had been flagged by expressions of concern, citing problems with duplications. What’s more, the journal added another expression of concern to a 2009 paper on which Saad — based at the University of Campinas in São Paulo, Brazil — is listed as last author, again over concerns of duplication.
This isn’t Saad’s first run-in with the journal: In 2015, the researcher sued the publisher, the American Diabetes Association, after it issued expressions of concern for four of his papers. Later that year, a judge dismissed Saad’s defamation suit. The journal eventually retracted the papers.
The latest articles flagged by Diabetes appear to be part of an intricate publishing web, as the journal suggests all papers have used features of previous papers, and also include elements that have been republished by subsequent articles.
Yesterday we reported that Elsevier journals had pulled three papers by a computer scientist with an impressive publication record. The publisher has since informed us that it plans to pull six more, again citing duplication and manipulation of the peer-review process.
Shahaboddin Shamshirband at the University of Malaya in Kuala Lumpur, Malaysia’s record will be down by a total of nine papers once the publisher issues the additional notices. We also found evidence that an additional paper was removed by a journal, but haven’t confirmed if that’s a retraction.
One of Shamshirband’s co-authors has objected to one of the retractions Elsevier has already issued for faked reviews, arguing the reviewers were PhD students without institutional email addresses. A spokesperson for Elsevier told us:
A computer scientist in Malaysia has lost two papers for faked peer reviews, and another for duplication. A fourth paper on which he is a co-author appears to have simply disappeared.
One retraction lays the blame for the fake reviewer on corresponding author Shahaboddin Shamshirband at the University of Malaya in Kuala Lumpur, Malaysia. According to the journal, Shamshirband — who has co-authored more than 200 papers and book chapters, despite receiving his PhD in 2014, according to his biography on Vitae — supplied a fake email for the reviewer during the submission process.
Here’s the retraction notice for that paper, issued by the journal Measurement:
A journal has retracted six papers by a cancer researcher at the University of Maryland in Baltimore, bringing his total to 10.
The retractions cite an investigation by the university, and detail problems ranging from duplicated images, to tweaking an image to conceal particular bands, to including unreliable data.
Three of the papers had already been flagged by the journal with expressions of concern. The last author on all the papers is Anil Jaiswal, a professor in the pharmacology department. He has issued four previous retractions.
Bruce Jarrell, the Chief Academic and Research Officer and Senior Vice President at the University of Maryland, told us at least two more retractions are forthcoming:
After a research group submitted two similar papers only days apart to different journals, one journal has retracted the paper — and told the other it should do the same.
The papers, by a group of authors based in Romania, describe a new polymer to stop the formation of biofilms. After a reader flagged the papers — which were submitted within eight days of each other in September, 2015 — as being similar, a journal has retracted one, and recommended the other journal retract the second. Although the second journal told us it planned to flag the paper with a notice alerting readers to the duplication, the notice has not yet appeared online.
The journal that issued the retraction — the International Journal of Polymer Analysis and Characterization (IJPAC) — called it a “a clear case of self-plagiarism,” according to the notice:
According to Jeanine D’Armiento, the study’s last author, the newly retracted paper in Clinical Science contained a figure from a Journal of Hypertension paper published by the same authors earlier that year.
According to the retraction notice in Intelligent Automation & Soft Computing, the authors didn’t cite or acknowledge the other study in the Turkish Journal of Electrical Engineering & Computer Science.
First author of both papers, Şeref Sağıroğlu, who is based at Gazi University in Ankara, Turkey told Retraction Watch that he doesn’t believe the two papers have significant overlap. Still, the research is related, so when he learned the retracted paper didn’t reference the previous one:
One paper published in 2012 was retracted — at the researcher’s request — for copying from a 2010 paper of his. In turn, both papers were duplicated in a paper that was published in 2016, and retracted a few months later. That 2016 paper borrowed from another paper published last year, which was quickly retracted after we contacted the journal.
These papers — by Dilip Kumar Das, listed at T. M. Bhagalpur University in India — were flagged in March by a PubPeer commenter.
In December, Plant Cell, Tissue and Organ Culture (PCTOC) retracted Das’s 2012 paper; here’s the retraction notice:
