Spanish lab admits to image manipulation, retracts one paper, corrects another

JBCA group has retracted one paper and corrected another in the Journal of Biological Chemistry (JBC) for image manipulations.

Last author José G. Castaño told us the manipulation occurred at the Universidad Autónoma de Madrid, where he and one other co-author are based. He declined to name who was responsible.

Here’s the retraction notice for “Cytomegalovirus promoter up-regulation is the major cause of increased protein levels of unstable reporter proteins after treatment of living cells with proteasome inhibitors:”

Retraction appears for group whose former member was sanctioned by ORI

Journal of Biological ChemistryResearchers whose former colleague was recently reprimanded by the U.S. Office of Research Integrity (ORI) have retracted a biology paper for duplication.

The retraction includes some familiar names: The last author Steven Grant, senior author of the newly retracted study, is also the last author of 11 papers flagged in a report by the ORI in December, 2015. That report focused on Girija Dasmahapatra, a co-author of the 11 studies who was also based at at Virginia Commonwealth University (VCU). Dasmahapatra left VCU in 2015, and is not listed on the latest retraction.

The retracted paper, published in The Journal of Biological Chemistry (JBC), was also co-authored by Paul Dent, a biochemist at the VCU, who we mentioned last year when he offered to retract another paper in Molecular Pharmacology after concerns arose on PubPeer. The journal has instead issued a lengthy correction (what we call a “mega-correction”).

A VCU spokesperson told us:

A plagiarism loop: Authors copied from papers that had copied from others

2Note to self: If you’re going to duplicate your own work, don’t copy from papers that plagiarize others’ research.

Just such a mistake has cost a PhD candidate three papers — although his co-author argues that a company is in part to blame.

Hossein Jafarzadeh, who is studying mechanical engineering at the University of Tehran, apparently asked a company to complete photomicroscopy for his work. Instead of doing to the work, the company provided him with an image taken from another paper, according to Karen Abrinia, his co-author, who is based at the same institution.

That’s the explanation that Abrinia gave when we asked about three retractions that the pair share, at least.

What the notices tell us is a little more convoluted. Plagiarized material from two different papers ended up in two different papers by the pair. Then, the researchers copied from their own papers in a third paper. (We’re unclear if Abrinia attributes every step of the mess to a company or not. Confused yet?)

Sting operation forces predatory publisher to pull paper

Medical Archives

Sometimes, the best way to expose a problem with the publishing process is to put it to a test — perhaps by performing a Sokal-style hoax, or submitting a paper with obvious flaws.

In 2014, that’s just what a researcher in Kosovo did. Suspicious that a journal wasn’t doing a thorough job of vetting submissions, she decided to send them an article of hers that had already appeared in another journal. Her thinking was that any journal with an honest and thorough peer review process would hesitate to publish the work. But this journal didn’t — at least at first. Though they retracted the paper this summer, it took a few twists and turns to get there.

The researcher wasn’t the only one wary of the journal — it’s on Jeffrey Beall’s list of “potential, possible, or probable” predatory publishers. Appropriately, Beall recounts the story of her sting operation on his blog. Here’s how it all went down:

Former NIH postdoc doctored data

ori-logoA genetics researcher included falsified data in two published papers, according to a report by the U.S. Office of Research Integrity (ORI) released today.

At the time of the misconduct, Andrew Cullinane was a postdoctoral fellow in the Medical Genetics Branch at the National Human Genome Research Institute (NHGRI). According to his LinkedIn page, he is now an assistant professor at Howard University in Washington D.C. The university’s College of Medicine lists him as an assistant professor in the Basic Sciences/Anatomy department.

As today’s notice in the Federal Register reports, Cullinane Continue reading Former NIH postdoc doctored data

A prominent researcher in Scotland has been suspended amidst a misconduct investigation at the University of Dundee.

According to The Scotsman, the allegations against Robert Ryan center around falsifying data and duplicating figures in his work about molecular bacteriology.

You’ve been dupe’d: Results so nice, they’re published twice

obesity surgeryWith retraction notices continuing to pour in, we like to occasionally take the opportunity to cover several at a time to keep up.

We’ve compiled a handful of retractions that were all issued to papers that were published twice by at least one of the same authors — known as duplication. (Sometimes, this can be the publisher’s fault, although that doesn’t appear to be the case in any of the following examples.)

So here are five recently retracted papers that were pulled because of duplication: Continue reading You’ve been dupe’d: Results so nice, they’re published twice

Five more retractions for researcher who sued PubPeer commenters brings tally to 18

Fazlul Sarkar
Fazlul Sarkar

A cancer researcher who tried to sue PubPeer commenters for criticizing his work has earned five more retractions, bringing his total to 18. 

All of the new retractions for Fazlul Sarkar, formerly based at Wayne State University in Michigan, appear in the International Journal of Cancer. All cite an institutional investigation, and relate to issues with images.

With 18 retractions, Sarkar has now earned a spot on our leaderboard.

We first encountered Sarkar when he subpoenaed PubPeer to reveal the names of anonymous commenters that potentially cost him a job at the University of Mississippi. Earlier this month, a Wayne State spokesperson confirmed to us that Sarkar has now retired from the university. (To get up to speed, check out our timeline on the major events in this case.)

Here’s the first of the retraction notices, issued today: Continue reading Five more retractions for researcher who sued PubPeer commenters brings tally to 18

Researcher in Brazil earns 12th retraction for recycling text and figures

Thermochimica ActaA scientist in Brazil has gained his twelfth retraction for reusing text and figures from previously published papers.

In 2011, Elsevier announced that it would retract 11 papers by Claudio Airoldi, a researcher at the State University of Campinas (UNICAMP) in Brazil. Subsequently, he was suspended for 45 days, and his co-author on the 11 previously pulled papers, Denis de Jesus Lima Guerra, lost his post at the Federal University of Mato Grosso (also in Brazil).

Now, a 12th retraction has appeared for Airoldi — this time in Thermochimica Acta.

Here’s the latest retraction notice, issued earlier this year: Continue reading Researcher in Brazil earns 12th retraction for recycling text and figures

Journal flags two papers by prominent diabetes researcher, more questioned on PubPeer

DiabetesDiabetes has issued two expressions of concern (EOCs) for papers co-authored by leading diabetes researcher Kathrin Maedler, adding to her previous count of one retraction and three corrections.

Both papers were questioned on PubPeer, alongside several others co-authored by Maedler, who is based at the University of Bremen in Germany. As we previously reported, PubPeer comments have led to one retraction for Maedler in the Journal of Biological Chemistry (JBC), and corrections in various other journals.

One of those corrections has now earned an EOC from Diabetes, which also extends to the original paper. Here are the notices, which asks the University of Bremen to investigate further:  Continue reading Journal flags two papers by prominent diabetes researcher, more questioned on PubPeer
