Duke scientists lose eight papers for alleged image manipulation

Salvatore Pizzo

Eight papers by two emeritus researchers from Duke University have been retracted in recent months for alleged image duplications. Although the researchers had worked at the university for decades, Duke officials have not responded to repeated inquiries about the retractions. 

The papers were published between 2004 and 2014 in The Journal of Cellular Biochemistry and PLOS One. According to the retraction statements, the articles contained images and figures that appeared similar or identical to others in the same paper or published elsewhere. 

The two researchers, Salvatore Pizzo, a former chair of Duke’s Department of Pathology, and his colleague Uma Kant Misra, spent much of their careers studying prostate cancer.  From 1993 to 2015, Pizzo and Misra published 70 papers together, with 26 where they are the only authors. Pizzo did not respond to repeated emails from Retraction Watch asking for comment. Misra died Sept. 18.

Fazlul Sarkar

An investigation at Wayne State University has prompted five retractions for a scientist who is suing PubPeer commenters after they criticized his work on the site.

The investigation into Fazlul Sarkar and his co-authors found that the papers contain images that were “inappropriately manipulated” or “inappropriately re-used and re-labeled.” All five retraction notices are from the Journal of Cellular Biochemistry.

Here’s the retraction notice for “Concurrent inhibition of NF-κB, cyclooxygenase-2, and epidermal growth factor receptor leads to greater anti-tumor activity in pancreatic cancer:

Wiley published a biology paper in the wrong journal

Screen Shot 2016-01-04 at 2.47.07 PMWiley Periodicals is withdrawing a biochemistry paper after mistakenly publishing it in the wrong journal.

The mistake took a few months to sort out.  Wiley initially published “Protein Kinase C Is Involved in the Induction of ATP-Binding Cassette Transporter A1 Expression by Liver X Receptor/Retinoid X Receptor Agonist in Human Macrophages” online in Journal of Cellular Physiology in May of last year. The article was posted in the correct journal — Journal of Cellular Biochemistry — in July.

At the very end of 2015, the publisher officially withdrew the version it posted in the Journal of Cellular Physiology.

Here’s the withdrawal note (which is paywalled — tsk, tsk):

Figure dupe sinks cell bio paper

cellular biohemTulane researchers Tong Wu and Chang Han, who have been anonymously accused of figure duplication in the past, have now finally lost a paper for that reason.

The frequent plagiarism tipster Juuichi Jigen (a pseudonym) set up a blog in 2012 alleging that the pair inappropriately reused images in six other papers, though none of those have been retracted. The recent notice, issued at the end of January by the Journal of Cellular Biochemistry, states that the figure duplication was confirmed by the University of Pittsburgh’s Office of Research Integrity. Han, the first author, was at UPitt when the paper was published in 2008, though she moved to join Wu at Tulane in 2009.

Yesterday, we reported that Sunil Kumar Manna, the head of immunology at India’s Centre for DNA Fingerprinting and Diagnostics, had retracted two papers for image problems.

Turns out Manna will be retracting eight more, he told us today. Here they are: Continue reading Scientist whose work is “not fully supported by the available laboratory records” to retract 8 more papers

Pulp fiction: doubtful “veracity” leads to retraction of endodontics paper

This one’s like taking candy from a baby.

The Journal of Endodontics — or JOE — has retracted a 2011 article (its online date) on the prospects of tissue engineering for the mouth by a group of Chinese authors who appear to have tried to pass bogus data into print.

The paper was titled “Mineralized Tissue Formation by Bone Morphogenetic Protein-7–transfected Pulp Stem Cells“. According to the notice: Continue reading Pulp fiction: doubtful “veracity” leads to retraction of endodontics paper
