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

Journal of Cellular PhysiologyAuthors 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.

Plagiarism was “not an intentional act,” says first author of retracted TB paper

logoA 2013 review article about tuberculosis is being retracted for “unacknowledged re-use of significant portions of text” from another article, which the first author said wasn’t intentional.

Sayantan Ray, based at Medical College and Hospital, Kolkata in India, told us that “most of the unchanged text” is present in sections written by junior co-authors. Since there doesn’t appear to be any attempt to cover it up, he argued anyone responsible for the plagiarism must not have realized it was wrong:

You can appreciate that this type of obvious similarity can only happen when the concerned person [does] not have any idea about [the] plagiarism issue.

According to the notice, published by Therapeutics and Clinical Risk Management, most of the re-used text appears to have come from a 2012 paper in the Indian Journal of Medical Research. Here’s more from the notice:

Authors retract highly cited Nature quantum dot letter after discovering error

cover_nature

Authors have retracted a highly cited Nature letter that purported to discover a much sought-after, stable light source from quantum dots, after they realized the light was actually coming from another source: the glass the dots were affixed to.

When the paper “Non-blinking semiconductor nanocrystals” was published in 2009, it received some media coverage, such as in Chemistry World. That’s partly because very small sources of “non-blinking” light could have wide-ranging, big-picture applications, author Todd Krauss, a physical chemist at the University of Rochester, told us:

Off the top of my head, a quantum computer. Quantum cryptography is another one. People want a stable light source that obeys quantum physics, instead of classic physics.

The retraction note, published Wednesday, explains how the researchers found out the effect was coming from the glass, not quantum dots:

Authors retract two neuroscience papers for duplication and plagiarism

Journal of NeurosurgeryA 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

10.cover

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:”

Retracted child labor paper “was improperly attributed,” copied text verbatim

C1 PAGE.inddThe American Journal of Public Health has retracted a paper after it was published online, when editors discovered that the author had plagiarized text verbatim and attributed the material to completely different sources.

“Child Farm Laborers” discusses child labor through the lens of the American photographers that documented the lives of young farm workers at the beginning of the century, such as Lewis Hine. It was authored Aung Zaw Win, whose affiliation on the paper is listed as Notre Dame de Namur University, in California.

The article was slated to be published in the journal’s August issue but editors printed the retraction shortly after it posted online. Here’s the notice:

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

Screen Shot 2015-10-28 at 8.40.00 PMJAMA 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

87959_relDNA 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

ori-logoA 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

Bone researcher manipulated data in JAMA study, says investigation

Screen Shot 2015-10-27 at 10.53.53 AMA bone researcher manipulated data in a 2011 JAMA study about an inexpensive treatment for osteoporosis. That’s the conclusion of an investigation at the researcher’s former workplace, the Women’s College Hospital in Toronto, the Toronto Star reports.

The study — led and manipulated by Sophie Jamal — followed 243 women over two years, as they applied nitroglycerin ointment once a day. The ointment is currently used to prevent chest pain and treat anal fissure pain by relaxing blood vessels; Jamal’s study concluded it could help patients with osteoporosis, too:

Among postmenopausal women, nitroglycerin ointment modestly increased [bone mineral density] and decreased bone resorption.

But even the modest effect was too good to be true. Continue reading Bone researcher manipulated data in JAMA study, says investigation
