Biochem journal retracts paper for “striking level of similarity” with another

Molecular and Cellular Biochemistry CoverA biochemistry journal has pulled a paper after deciding that its layout and content overlapped significantly with a previously published paper.

The researcher who reported the similarity to Molecular and Cellular Biochemistry has sent us his correspondence with the journal. After a “thorough investigation,” the journal felt the paper was worth retracting.

Here’s the retraction notice for “TNF receptor-associated factor 6 regulates proliferation, apoptosis, and invasion of glioma cells:” Continue reading Biochem journal retracts paper for “striking level of similarity” with another

Nutrition study pulled after statistical flaws emerge

Nutrition JournalA paper that suggested that eating flaxseed could reduce inflammation in men at risk of heart disease has been retracted, after researchers pointed out the paper’s flaws.

The retraction is part of a large initiative on the part of nutrition researcher David Allison and colleagues to clean up the literature, which we’ve previously covered. Regarding this paper, he told us:

When we looked at the study…it was very clear that the statistical methods used were not correct. These are not matters of debate or opinion, these are just…verifiably incorrect.

The Nutrition Journal published the paper in January 2015, and retracted it in June 2016, one day after publishing a letter by Allison and a colleague critiquing the paper. 

Here’s the retraction notice for “Impact of weight loss diet associated with flaxseed on inflammatory markers in men with cardiovascular risk factors: a clinical study:” Continue reading Nutrition study pulled after statistical flaws emerge

Researcher faked emails for co-authors, submitted paper without consent

A material science journal has retracted a paper after discovering that the first author faked email addresses for co-authors to submit the paper without their permission.

The journal, Materials, also discovered that the 2016 paper had plagiarized material from a 2013 paper previously published in Metallurgical and Materials Transactions A.

Here’s the retraction notice for the paper: Continue reading Researcher faked emails for co-authors, submitted paper without consent

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

Bone researcher up to 10 retractions

Neurology JournalA journal is retracting three papers and a letter from a bone researcher who admitted to scientific misconduct, noting that all co-authors were included only for honorary reasons.

We’ve previously reported on six retractions of papers co-authored by Yoshihiro Sato, who is based at Mitate Hospital in Japan, including one in JAMA. Retractions stemmed from the use of “honorary” co-authors, as well as concerns over the data. One paper seemed to be the victim of “extensive self-plagiarism.”

Sato, who is the first and corresponding author of all ten retractions (including the letter), accepted full responsibility of the newly retracted publications, noting that none of the co-authors took part in any misconduct.

Here’s the retraction notice — which is similar for all four new retractions — issued on July 12: Continue reading Bone researcher up to 10 retractions

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.

4th retraction for neuroscientist sentenced for fraud

Bruce Murdoch
Bruce Murdoch

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

Against authors’ wishes, journal pulls study with errors, statistical mistake

Annals of the Rheumatic DiseasesA rheumatology journal has retracted a paper about treating knee pain after an institutional investigation found a mistake in the statistical process.

Over several months, the authors proposed a series of corrections to the 2014 study. However, the journal Annals of the Rheumatic Diseases (ARD) decided that there were “unresolved concerns” about the reliability of the data, and decided to retract the paper entirely, despite the authors’ objections.

Here’s the retraction notice: Continue reading Against authors’ wishes, journal pulls study with errors, statistical mistake
