Cholesterol paper duplicated; “The authors believed that they had taken the necessary steps to withdraw.”

A review journal is pulling a 2013 article about advances in researchers’ understanding of cholesterol after seeing the same article in another journal.

Although the retracted paper appeared first — online in Biological Reviews in February, 2013 — the journal decided to retract it after learning the authors had initially submitted it elsewhere. The first submission was eventually published (with the exception of one author) in 2014 in Frontiers in Bioscience.

The authors say they “believed that they had taken the necessary steps to withdraw their paper from Frontiers in Bioscience before they submitted to Biological Reviews in June 2012.” Here’s more from the retraction notice:

“Dual submission issues” retract both copies of ovarian cancer paper

Authors of a study on a potential biomarker for ovarian cancer have been hit with two retractions after the results were published twice.

We don’t usually see both copies of a duplicated paper retracted, but this is a somewhat unusual case. In November 2011, a group of authors submitted the paper to Gynecologic Oncology. But two months’ prior, the first author had decided to also submit the paper to the Journal of Cellular Physiology, without listing three of the other researchers, including the primary author on the paper. It was published by the Journal of Cellular Physiology first, then by Gynecologic Oncology, both in July, 2012.

Jie Chen, first author on both articles, “takes full responsibility for the dual submission” and “other co-authors should be exempted from all responsibilities,” as the retraction notice from Gynecologic Oncology explains.

Authors retract two neuroscience papers for duplication and plagiarism

A tipster’s complaints have led to the retraction of two papers in the Journal of Neurosurgery for “plagiarism, duplicate publication, and copyright infringement.”

The corresponding author for both papers, Hung-Chuan Pan of Taichung Veterans General Hospital, had contacted the journal about publishing an erratum for one of the articles when the journal was tipped off by an email pointing out deeper problems in the two retracted papers.

The tipster provided evidence that alleged “a violation of ethics on the part of the authors,” according to the communications manager at the JNS Publishing Group, Jo Ann Eliason.

Both retraction notices, published October 2, detailed a number of “similarities” and “overlaps” in the papers.

Duplicated data, “careless errors” expire lung cancer paper

A paper about the molecular details of lung cancer is being retracted for repeating datasets and “careless errors” in a pair of figures.

According to the note, the editor of Carcinogenesis wouldn’t have known about the problems if he hadn’t been tipped off that the paper by first author, XiaoJuan Sun — a researcher at Shenzhen Second People’s Hospital in China — shared “significant similarities” with another one of Sun’s papers that was retracted years ago. After the journal investigated the paper, it discovered that the authors had reported the same data as in the retracted paper “without significant additions or amendments,” along with some errors and inconsistencies.

Here’s the detailed note for “The EDA-containing cellular fibronectin induces epithelial mesenchymal transition in lung cancer cells through integrin α9β1-mediated activation of PI3-K /Akt and Erk1/2:”

Journal retracts — and republishes — small study on gamma rays for OCD

JAMA Psychiatry has retracted and republished a paper on a cutting-edge procedure for patients with obsessive compulsive disorder.

In the original paper, the authors claimed that three out of eight patients who underwent a procedure that used gamma rays to kill brain cells showed improvements 12 months later (versus zero in the group who underwent a “sham” procedure). But after a reader noticed an “inadvertent” error in the calculation of how many patients had improved, the authors realized that only two of the patients had responded meaningfully to the procedure.

The new results “did not reach statistical significance,” the authors write in a “Notice of Retraction and Replacement.” JAMA Psychiatry published it yesterday, along with a new version of the article, a letter from psychiatrist Christopher Baethge pointing out the error, and an editorial. The original article is available in the supplemental material of the new version, with the errors highlighted.

Here’s the note in full for “Gamma ventral capsulotomy for obsessive-compulsive disorder: a randomized clinical trial,” which explains the error:

Biology journal bans plagiarizers, reviewers with non-institutional email addresses

DNA and Cell Biology has declared it will ban any authors who submit plagiarized manuscripts for three years, and will no longer accept suggestions of reviewers with non-institutional email addresses.

The move comes after a wave of hundreds of retractions stemming from fake peer reviews, often occurring when authors supply fake emails for suggested reviewers.

In an editorial published online October 23, editor Carol Shoshkes Reiss notes that the decision to ban authors who plagiarize material stems from a rash of recent submissions containing overlapping text: Continue reading Biology journal bans plagiarizers, reviewers with non-institutional email addresses

Taste researcher falsified data in two papers: ORI

A federal report has found that a former University of Maryland postdoc “falsified and/or fabricated” data in two papers about taste receptors.

The Office of Research Integrity report found that Maria C.P. Geraedts manipulated bar graphs in the papers to “produce the desired result.” Both have been retracted. Geraedts left academia in 2014, and is now a science writer.

We reported on one retraction in July, “Gustatory stimuli representing different perceptual qualities elicit distinct patterns of neuropeptide secretion from taste buds,” published in The Journal of Neuroscience.

The other, “Transformation of postingestive glucose responses after deletion of sweet taste receptor subunits or gastric bypass surgery,” published in 2012 in the American Journal of Physiology Endocrinology and Metabolism, was retracted in September. Here’s the note, which cites the university’s investigation: Continue reading Taste researcher falsified data in two papers: ORI

Author with three retractions objects to mega-correction following investigation

We’ve uncovered a “mega-correction“ for a 2010 paper in Development, posted as the result of an investigation into the first author which has already led to three retractions.

Last year, the Utrecht University investigation into Pankaj Dhonukshe found “manipulation in some form” in four papers, and concluded that he committed a “violation of academic integrity.” The investigation also led to the retraction of a 2012 Cell paper and two papers in Nature that were co-authored by Dhonukshe.

Development began investigating the corrected paper after being contacted by one of the authors and alerted to the results of the university’s investigation. The notice includes a statement from Dhonukshe objecting to the correction. Continue reading Author with three retractions objects to mega-correction following investigation

P53 researcher submitted paper “without permission from his co-authors”

One issue that we see pretty regularly is a paper submitted by one author without the permission of the others.

That’s what’s happened with “p53-induced Rap2B positively regulates migration in cells exposed to glucose deprivation,” published in July by Molecular Carcinogenesis. The paper looks at a protein called p53, well-known to regulate cell growth and, when mutated, cause cancer.

Here’s the pretty straightforward retraction note:

University investigating duplicated images in retracted paper

The authors of a Cell Metabolism paper are pulling it after discovering blot images that “appear more than once in independent and unrelated experiments.”

Just how the duplication occurred in the 2009 paper — about transcription of mitochondrial DNA — remains a mystery, the authors note:

…the reasons for the errors are still under investigation…

Meanwhile, we’ve learned that the last author on the paper — Carlos Moraes of the University of Miami — has requested a retraction for another 2013 paper in Mitochondrion, also co-authored by Tina Wenz at the University of Cologne in Germany. That paper is among multiple publications co-authored by Moraes and Wenz that have been flagged on PubPeer.

We’ve reached out to the parties involved, and received a warning from an attorney representing Wenz that if we write about Continue reading University investigating duplicated images in retracted paper
