Figure misuse leads to retraction of wound healing paper

biochemengjrnA group of researchers from India and China has lost a 2012 article in the Biochemical Engineering Journal for lifting a figure from a previously published article from another team of investigators. Evidently, caught red-handed, they haven’t copped to the caper.

The article was titled “Purification and characterization of organic solvent and detergent stable protease isolated from marine Saccharopolyspora sp. A9: Application of protease for wound healing.” According to the retraction notice: Continue reading Figure misuse leads to retraction of wound healing paper

Like pulling teeth? Dental implant papers retracted for duplication

jomscoverA group of Brazilian dental researchers has lost two 2012 papers for duplication — twice the typical body count for such situations.

The two articles appeared in the Journal of Orthodontics and the Journal of Oral and Maxillofacial Surgery about four months apart.

The first, from the JOMS, “Selective Use of Hand and Forearm Muscles During Bone Screw Insertion: A Natural Torque Meter,” was published online Aug. 30 — just about the time the Journal of Orthodontics was accepting the duplicate submission.

As the JOMS retraction notice states: Continue reading Like pulling teeth? Dental implant papers retracted for duplication

“Missing link” fungus-like organisms still missing as paper is retracted

proteincellThe journal Protein & Cell has retracted a 2012 paper on fungi-like organisms that took a step in the direction of proper citation — but didn’t quite get there.

The article, “Cryptomycota: the missing link,” came from Krishna Bolla and Elizabeth Jane Ashforth, who are affiliated with Key Laboratory of Pathogenic Microbiology at the Chinese Academy of Sciences in Bejing.

But as the retraction notice explains, Bolla wasn’t careful enough about good publishing hygiene: Continue reading “Missing link” fungus-like organisms still missing as paper is retracted

Infant formula paper smells like salami, retracted

semperinatolcoverSeminars in Perinatology has retracted a 2002 paper by a group of authors in France and Belgium who’d used a previously published article (their own) as a template for the benighted work.

The article, “Nitrogen utilization and bone mineralization in very low birth weight infants fed partially hydrolyzed preterm formula,” by Jean-Charles Picaud and colleagues, appeared in December 2002. But it was based largely on this May 2001 paper in the Journal of Pediatric Gastroenterology and Nutrition, titled “Nutritional Efficacy of Preterm Formula With a Partially Hydrolyzed Protein Source: A Randomized Pilot Study.”

According to the retraction notice:

A double-bill from Digestive Diseases and Sciences, both for regurgitation — aka duplication

ddsComing back up?

Digestive Diseases and Sciences has retracted two papers for duplication.

The first paper, “Membrane-Bound Mucins and Mucin Terminal Glycans Expression in Idiopathic or Helicobacter pylori, NSAID Associated Peptic Ulcers,” was published in October 2012 by a group from Israel and the United States. It found that:

Cytoplasmic MUC17 staining was significantly decreased in the cases with idiopathic ulcer. The opposite was demonstrated for MUC1. This observation might be important, since different mucins with altered sialylation patterns likely differ in their protection efficiency against acid and pepsin.

But, as the retraction notice suggests, that much had been found before: Continue reading A double-bill from Digestive Diseases and Sciences, both for regurgitation — aka duplication

Retraction cites “unintended excessive reuse” in commentary — of paper it was praising

rejuvreschcoverWe here at Retraction Watch HQ are always on the lookout for euphemisms for plagiarism (and other misconduct, of course). Among our favorites are “referencing failure” and the journal that allowed researchers to call plagiarism an “approach” to writing.

Here’s a new one that’s sure to do well with voters.

The journal Rejuvenation Research has retracted a commentary for, well, containing too much of the very text it was supposed to be commenting on.

The editorial was by Giorgio Aicardi, of the University of Bologna, in Italy, and the article Aicardi was writing about was titled “Synaptic distributions of GluA2 and PKMζ in the monkey dentate gyrus and their relationships with aging and memory.” That article had been published in the Journal of Neuroscience last year by a group from Mount Sinai in New York.

We’ll let the notice do the explaining: Continue reading Retraction cites “unintended excessive reuse” in commentary — of paper it was praising

Updated: Integrity “uncertain,” journal retracts stroke paper

emmcover

Experimental & Molecular Medicine has retracted a 2012 paper on stroke by a group of South Korean researchers after learning that one of the figures in the article was unreliable.

The article was titled “Protective effects of transduced Tat-DJ-1 protein against oxidative stress and ischemic brain injury,” and it came from a team at Hallym University in Chunchon.

According to the retraction notice: Continue reading Updated: Integrity “uncertain,” journal retracts stroke paper

Duplicate submission costs authors two papers on Parkinson’s disease

neuropeptidecoverA group of pharmacology researchers in the UK has lost two papers after submitting effectively identical versions to different journals — and getting them accepted, of course — just a day apart.

The first article appeared on the British Journal of Pharmacology‘s website on July 10, 2012. It was titled “Exendin-4 reverts behavioural and neurochemicaldysfunction in a pre-motor rodent model of Parkinson’s disease with noradrenergic deficit.”

Paper 2 appeared in the journal Neuropeptides in October, although it has an online pub date of August 24, and was titled “Exendin-4 reverses biochemical and behavioral deficits in a pre-motor rodent model of Parkinson’s disease with combined noradrenergic and serotonergic lesions.”

Amid a legal dispute, journal downgrades a retraction to an expression of concern

cellcyclecoverThe journal Cell Cycle is expressing a “note” of concern about a 2012 paper by a former researcher at the University of Minnesota, who has claimed that her mentor at the institution was violating her copyright. It turns out the journal had briefly retracted the paper, but reversed itself with the expression of concern — a curious about-face that, in our experience, often indicates the work of lawyers.

That seems to be the case here, too.

The article, “Chalcone-based small-molecule inhibitors attenuate malignant phenotype via targeting deubiquitinating enzymes,” was already the subject of an erratum, available here:

Cell attributes image problems in cloning paper to “minor” errors; sees no impact on conclusions

cell cloningYesterday we reported that Cell was looking into problematic images in a recent paper on human embryonic stem cell cloning. We’ve now heard from the journal about the nature of the inquiry.

Mary Beth O’Leary, a spokeswoman for Cell Press — an Elsevier title — tells us that:

Based on our own initial in-house assessment of the issues raised in PubPeer and in initial discussions with the authors, it seems that there were some minor errors made by the authors when preparing the figures for initial submission.  While we are continuing discussions with the authors, we do not believe these errors impact the scientific findings of the paper in any way.
