A plastic surgery journal has retracted a paper after a researcher claimed it contained three figures without his permission.
According to Aesthetic Surgery Journal’s retraction notice (which is paywalled, tsk tsk), the figures were reproduced from a paper published in a Chinese journal without the original authors’ knowledge or permission: Continue reading Journal retracts paper for using figures without permission
A 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
A paper that suggested that eating flaxseed could reduce inflammation in men at risk of heart disease has been retracted, after researchers pointed out the paper’s flaws.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
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
A 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
Last month, Ranjit Kumar Chandra was denied an extension to file an appeal of his lawsuit against the Canadian Broadcasting Corporation (CBC). It seemed to mark the end of a long fall for the self-proclaimed “father of nutritional immunology,” who has ended up with multiple high-profile retractions and on the wrong end of a costly libel lawsuit.
The case had a lot of twists and turns, however. So for your convenience, we’ve compiled a timeline of everything you need to know about the events that led up to the lawsuit — where it all began, and how it ended last July, when the Ontario Superior Court of Justice ruled in favor of the CBC, and the apparent epilogue this June.
In the 1980s, Chandra was a highly regarded nutrition researcher; in 1989, he was made a member of the Order of Canada. He authored over 200 papers during his time at Memorial University of Newfoundland. He has referred to himself as the “father of nutritional immunology,” but the link to his website no longer appears to be active.
Here’s how it all fell apart: Continue reading Who is Ranjit Kumar Chandra? A timeline of notoriety
A researcher is calling for the retraction of a paper about a recent ban in the use of organs from executed prisoners in China, accusing the authors of misrepresenting the state of the practice.
In April 2015, a paper in the Journal of Medical Ethics welcomed the ban by the Chinese government as “a step in the right direction,” but noted that China remains plagued by a crucial shortage in available organs.
Some academics disagreed with the authors’ take on the issue, noting that the paper fails to note that many organs may continue to be harvested from Chinese prisoners of conscience; ultimately, the journal received a letter asking to retract the paper. The journal decided not to, and instead asked the authors to issue a lengthy correction, for instance changing the language about the government decision (“law” became“guideline”), and allowed critics to publish a rebuttal to the paper in May 2016. Continue reading Is China using organs from executed prisoners? Researchers debate issue in the literature
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:

A 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
A 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
