A Hindawi journal has retracted two 2013 papers by a group of stem cell researchers in China over issues with the images in the articles, bringing their count to three.
Here’s the notice for “Side-by-Side comparison of the biological characteristics of human umbilical cord and adipose tissue-derived mesenchymal stem cells,” by Lili Chen and colleagues from Huazhong University of Science and Technology in Wuhan:

A researcher at the University of Maryland, along with two former colleagues, has had three papers retracted in the past six months following an institutional investigation that found evidence of image manipulation.
The three retractions share three authors: Hua Zhou, Ying Hua Yang and John Basile, an associate professor of oncology and diagnostic sciences at the institution. The original papers appeared in Angiogenesis and PLOS ONE between 2011 and 2013.
Basile told Retraction Watch that he was prohibited from discussing the matter, based on statements from the university’s investigation committee, but that he did not think other papers from his lab co-authored with Zhou would be retracted.
One of the articles, “Semaphorin 4D cooperates with VEGF to promote angiogenesis and tumor progression,” has been cited 46 times, according to Clarivate Analytics’ Web of Science. Here’s the retraction notice from Angiogenesis, which was published earlier this month:

King’s College London (KCL) found evidence of poor research practices by three of its faculty, but “no intention to deceive” and no misconduct, according to documents obtained by Retraction Watch.
One case involves work by cancer biologists Farzin Farzaneh and Ghulam Mufti, while the other involves work by Mahvash Tavassoli, also a cancer researcher. Both involve problems with images and were brought to the attention of KCL in January of this year by pseudonymous whistleblower Claire Francis.
In the Farzaneh and Mufti case, writes Tim Newton, KCL’s dean of research governance, ethics and integrity in an October 31 letter:

A researcher who is now up to six retractions has left his faculty position at the Rosalind Franklin University of Medicine and Science following a finding of research misconduct, Retraction Watch has learned.

A cancer researcher in England says he will be retracting a 2011 paper after acknowledging “unacceptable” manipulation of some of the figures in the article.
Richard Hill, of the University of Portsmouth, this week agreed to retract the article, “DNA-PKcs binding to p53 on the p21WAF1/CIP1 promoter blocks transcription resulting in cell death,” which appeared in the journal Oncotarget.
The paper, which Hill wrote while he was at Dalhousie University in Halifax, Nova Scotia, had drawn scrutiny on PubPeer four years ago, with one poster noting “many indications of blot image manipulation” in the figures. Additional comments appeared earlier this month.
In a comment on PubPeer posted this week, Hill wrote:

On March 30, 2018, The Ohio State University (OSU) released a 75-page report concluding that Ching-Shih Chen, a cancer researcher, had deviated “from the accepted practices of image handling and figure generation and intentionally falsifying data.” The report recommended the retraction of eight papers.
By the end of August of 2018, Chen had had four papers retracted — one in Cancer Research, two in the Journal of Medicinal Chemistry, and one in PLoS ONE.
But it wasn’t until more than a year after the report was released that the other four papers — two from Carcinogenesis, one from Clinical Cancer Research, and one from Molecular Cellular Therapeutics — were retracted, all between April 1 and May 1 of this year.
What took so long? Your guess is as good as ours; none of the editors of those journals responded to our requests for comment.

Retraction Watch readers may know the name Elisabeth Bik, whose painstaking work inspecting tens of thousands of Western blot images has led to dozens of retractions in journals including PLOS ONE. Today in The Scientist, we profile Bik, a microbiologist who calls herself a “super-introvert.”
Bik tells us:

A pair of researchers at the Indian Institute of Technology (Indian School of Mines) has had a total of nine more papers retracted, pushing their totals to 24 and 26, respectively.
The totals put the two researchers — Rashmi Madhuri, with 24 retractions, and Prashant Sharma, with 26 — on our leaderboard of the 30 authors with the most retractions in the world.
Three of the retractions appeared in RSC Advances, two appeared in Journal of Materials Chemistry B, and one each appeared in Journal of Materials Chemistry A, Journal of Materials Chemistry C, Biomaterials Science, and CrystEngComm.
For example, here is the retraction notice from Journal of Materials Chemistry C: Continue reading Pair of nanotech researchers up to at least two dozen retractions
A researcher in Spain who studies dental implants has had another six papers retracted, for a total of 18.
José Luis Calvo-Guirado‘s latest retraction, which along with the other 17 appeared in Clinical Oral Implants Research, a Wiley title, was for “image discrepancies resulting in unreliable data.” Three appeared in June, and two in July, also for image issues. The researcher also has at least two corrections; one in Annals of Anatomy — Anatomischer Anzeiger and one in Materials. Continue reading Dental researcher in Spain up to 18 retractions
