Second cell bio retraction from UPitt investigation of tweaked images

Journal of Cellular Physiology: Volume 229, Number 10, October 2Two researchers, Tong Wu and Chang Han, have lost a second paper as the result of a University of Pittsburgh investigation into image manipulations.

The first retraction, in Journal of Cellular Biochemistry, went live in February. The researchers, currently based at Tulane University, were originally tapped by pseudonymous tipster Juuichi Jigen, who created a website in 2012 to chronicle the allegations.

The blog lists six papers by the pair with supposedly questionable figures. According to Jigen, this latest retraction, in the Journal of Cellular Physiology, contains a figure (2A) that appears to reuse data from another paper, and another figure (3) where the data appear to be manipulated.

Second exercise study retracted in four-paper pileup

nursing and health scienceWe recently wrote about three papers on heart health and exercise that came under fire for reporting the same trial in three different ways. Actually, make that four ways (so far).

The Wiley journal Nursing and Health Sciences has retracted a fourth paper from the group, saying the “main study” was “previously published.” The notice mentions all three previous papers, one of which has already been retracted and another withdrawn from publication.

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up a blog in 2012 alleging that the pair inappropriately reused images in six other papers, though none of those have been retracted.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.

Heart study bleeds into three papers, one retracted and one withdrawn

janWith the increasingly hectic pace of modern life, everybody is always on the look out for time-saving tricks and tips.

Scientists at the National University of Singapore and the Hong Kong Polytechnic University certainly found one, but we really can’t recommend it: doing one randomized controlled trial (RCT) with several outcomes, and publishing them as three separate 2014 papers with “considerable overlap.”

So far, one paper has been retracted, and another withdrawn.

Second retraction appears for former accounting professor James Hunton

It took five months, but in December a second retraction popped up for disgraced accounting professor James E. Hunton.

Hunton resigned his teaching post at Bentley University in December of 2012. An extensive investigation by Bentley showed that not only was the data in two papers falsified. Hunton also lied about non-existent confidentiality agreements and tried to destroy evidence of his lies by unsuccessfully wiping his laptop and changing metadata on files.

The first paper Hunton was accused of faking, ironically about accounting fraud, was retracted in 2012.

Cut and paste and a PC crash: figure manipulations sink two papers

jnc

Two papers by an overlapping group of researchers in Italy have been retracted for manipulated figures.

In late 2013, perennial tipster Clare Francis sent their concerns about several papers, including the two that have been retracted, by authors who frequently publish together. One of the papers, in the Journal of Neurochemistry, is from a team led by Ferdinando Nicoletti; four other papers from the group have been criticized on PubPeer for image manipulation, which he addressed via email with us.

The second retracted paper, from the Journal of Immunology, has shares one author with the first: Patrizia Di Iorio of the University of Chieti, though according to Nicoletti she had no role in preparing the figures.

Here’s the April 2014 notice for “Neuroprotection mediated by glial group-II metabotropic glutamate receptors requires the activation of the MAP kinase and the phosphatidylinositol-3-kinase pathways” in the Journal of Neurochemistry. It’s behind a paywall, but the journal has assured us this is against policy and they will be fixing it shortly:

Shigeaki Kato up to 33 retractions, with five papers cited a total of 450 times

Former University of Tokyo researcher Shigeaki Kato continues to put big numbers on the board.

Last month, we reported on his 26th, 27th, and 28th retractions, all in Nature Cell Biology and cited close to 700 times. Yesterday, EMBO Journal and EMBO Reports published a total of five more retractions for the endocrinology researcher, who resigned from the university in 2012 following investigations found he had faked images.

Here’s the notice for “A cell cycle-dependent co-repressor mediates photoreceptor cell-specific nuclear receptor function:” Continue reading Shigeaki Kato up to 33 retractions, with five papers cited a total of 450 times

It’s happened again: Journal “cannot rule out” possibility author did his own peer review

ijkcThomson Reuters’ online peer review system ScholarOne is having quite a year.

This summer, a scientist exploited basic security flaws in how the system accepts author suggestions for peer reviewers to review a whole pile of his own manuscripts, ultimately resulting in the retraction of 60 papers and the resignation of the Taiwan minister of education.

Now, another journal that uses the system, Wiley’s International Journal of Chemical Kinetics, has retracted a paper because the authors provided their own peer reviewers and “the identity of the peer reviewers could subsequently not be verified.”

We asked editor Craig A. Taatjes if he was concerned the authors had conducted their own peer review. His response is reflective of many of the breaches we’ve seen so far for these online systems: Continue reading It’s happened again: Journal “cannot rule out” possibility author did his own peer review

Networking paper retracted for “overlap” with author’s prior publication

jmanagementstudiesHere at Retraction Watch, we have a lot of fun exploring all the different kinds of science that cross our paths.

Some, though, we’re just not qualified to understand, like this retracted paper in the Journal of Management Studies, which according to the abstract “demonstrates that the persistence of brokerage positions decreases broker performance.”

What is clear is the retraction: the author already published the conclusion in a Japanese management journal in 2011.

Here’s the notice: Continue reading Networking paper retracted for “overlap” with author’s prior publication

Hepatology issues corrections in two papers from Pitt liver group

hepatology A group of liver researchers from the University of Pittsburgh has earned a pair of corrections in Hepatology for image problems.

The team was led by George K. Michalopoulos, chair of the department of pathology at the University of Pittsburgh Medical Center.

One article, “Excessive hepatomegaly of mice with hepatocyte-targeted elimination of integrin linked kinase following treatment with 1,4-bis [2-(3,5-dichaloropyridyloxy)] benzene,” appeared in January 2011. According to the notice: Continue reading Hepatology issues corrections in two papers from Pitt liver group
