Plagiarism and duplication can be deadly to a paper in any dose. In the case of a study on the toxicity of nanoparticles to plants, the publisher has presented the precise amount of plagiarism and duplications that ultimately felled the paper.

Specifically, according to Nanomaterials, 56% of “Potential Impact of Multi-Walled Carbon Nanotubes Exposure to the Seedling Stage of Selected Plant Species” was taken from other work.

Here are more details from the retraction notice, published last year:

Beleaguered plant scientist with 22 corrections avoids 3 more

CellCell will not be issuing corrections for three papers co-authored by prominent plant biologist Olivier Voinnet, after readers on PubPeer raised questions about some of the images. 

The news may be a welcome relief for Voinnet, based at ETH Zurich in Switzerland, who has recently issued 22 corrections and seven retractions. Ongoing questions about his work have also earned him a three-year funding ban, and caused the European Molecular Biology Organization to revoke an award.

On July 28, Cell published editorial notes for all three papers, which have been collectively cited more than 1000 times (also reported by Leonid Schneider). The notes say that the journal will take “no further action,” noting that the authors of the papers informed Cell of the problems with figures, which do not appear to compromise the papers’ overall validity.  

Here’s the first editorial note, for a 1998 paper: Continue reading Beleaguered plant scientist with 22 corrections avoids 3 more

A researcher sued critics of his work. Now he has 13 retractions.

A cancer researcher who sued PubPeer commenters for criticizing his work has lost six more papers, bringing his total to 13 retractions. 

Four of the new retraction notices issued by the journal Cancer cite an investigation at Wayne State University in Michigan into the work of Fazlul Sarkar and some of his colleagues. All the new notices, including the other two in Breast Cancer Research and Treatment, are for image-related issues.

Retraction Watch readers will recognize the name Fazlul Sarkar, who took PubPeer to court to unmask the anonymous critics whose comments cost him a job at the University of Mississippi. According to this document, Sarkar retired from Wayne State this year.  

Here’s the first of the four Cancer retraction notices, all of which were issued on July 29: Continue reading A researcher sued critics of his work. Now he has 13 retractions.

Romanian journal bans author following 4 retractions

Romanian Journal of Internal MedicineA medical journal in Romania has issued a lifetime ban for a researcher after retracting four of his papers.

Since April, the Romanian Journal of Internal Medicine (RJIM) retracted nine papers (eight for plagiarism, one for duplication); four of these were co-authored by Manole Cojocaru, a researcher at the Titu Maiorescu University (TMU) in Bucharest, Romania. Subsequently, the journal has banned Cojocaru from submitting manuscripts, and has also informed the ethics committee at his institution.

Here’s the retraction notice, which is the same for six of the papers: Continue reading Romanian journal bans author following 4 retractions

Journal retracts nutrition paper, citing authors’ “unethical behavior”

A journal has retracted a paper for a somewhat unusual reason — and swapped the article with an entirely new paper by different authors.

The journal, Materia Socio-Medica, said it’s retracting a paper about diet in dialysis patients because of some of the authors “un-ethical behaviors” in previous issues of the journal. In its place, the journal has published a paper about tuberculosis, also a curious move.

Here’s the retraction notice for “Effect of Diet Education on Blood Pressure Changes and Interdialytic Weight in Hemodialysis Patients Admitted in Hajar Hospital in Shahrekord:”  Continue reading Journal retracts nutrition paper, citing authors’ “unethical behavior”

Neuroscientist in Serbia earns 8th retraction amid investigation

RadenovicA neurobiologist has notched her eight retraction in the midst of an ongoing investigation into her work by her institution, the University of Belgrade in Serbia.

As we reported previously, a mass clean-up by the Archives of Biological Sciences (ABS), the official journal of the Serbian Biological Society resulted in six retractions of papers co-authored by Lidija Radenović. (Radenović served as vice president of the Serbian Biological Society until July 2014.)

In April, we reported that Radenović was about to notch her seventh retraction in Acta Neurologica Scandinavica; that paper has now been pulled, and ABS has retracted another one of her papers.

Here’s the retraction notice by ABS: Continue reading Neuroscientist in Serbia earns 8th retraction amid investigation

You’ve been dupe’d: Nice data — let’s see them again

As we’ve said before, with hundreds of retractions per year, there are simply too many for us to cover individually.

So from time to time we’ll compile a list of retractions that appeared relatively straightforward, just for record-keeping purposes.

Often, these seemingly straightforward retractions involve duplications, in which authors — accidentally or on purpose — republish their own work elsewhere.

Sometimes journals and authors blame this event on “poor communication,” our first example notes:

Four more retractions for biomaterials researcher brings total to 7

Journal of Controlled ReleaseA biomaterials researcher has lost four more papers for figure-related issues such as duplications, bringing his total to seven retractions.

We previously reported on three retractions — two by the Journal of Controlled Release (JCR) — of papers co-authored by Hossein Hosseinkhani, who is currently based at the National Taiwan University of Science and Technology in Taipei. Now, the JCR is pulling four more studies that list Hosseinkhani as a co-author.

Here’s the retraction notice for “Enhanced expression of plasmid dna – cationized gelatin complex by ultrasound in murine muscle:” Continue reading Four more retractions for biomaterials researcher brings total to 7

Author pulls study for duplication, blames editing company

MedChemCommThe author of a paper about insulin has retracted it due to “extensive text and data overlap” with another paper.

In November 2015, MedChemComm issued an expression of concern (EOC) for the same paper. According to the EOC, the author of the paper, Yong Yang, flagged the paper to the journal, citing problems with authorship and portions of text overlap, which Yang attributed to an editing company.  

The editor-in-chief of the journal told us Yang’s institution — China Medical University — carried out an investigation into the case at the journal’s request.

We’ve also found a 2015 retraction for Yang, after he published a paper without the okay of his previous institution in Texas. 

Here’s the retraction notice: Continue reading Author pulls study for duplication, blames editing company

4th retraction for neuroscientist sentenced for fraud

A Parkinson’s researcher has earned his fourth retraction after receiving a two-year suspended sentence for fraud.

The sentence for Bruce Murdoch, issued on March 31, 2016, came following an investigation by his former employer, the University of Queensland (UQ) in Australia, into 92 papers. Murdoch entered guilty pleas for 17 fraud-related charges, which resulted in the retraction of three papers co-authored by Murdoch and Caroline Barwood, another former UQ Parkinson’s researcher who faced fraud charges (and was granted bail in 2014).

Now, a fourth retraction has appeared for Murdoch in Brain Injury, this time for duplication and failing to obtain consent from his co-authors.

Here’s the retraction notice, issued on July 11: Continue reading 4th retraction for neuroscientist sentenced for fraud
