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.
A researcher at the University of Kentucky who studies the cancer risks of toxic chemicals has retracted three papers. All of the retraction notices, which appear in the Journal of Biological Chemistry, refer to some kind of image duplication. The papers were originally published between 2014 and 2017, with the 2014 paper cited 39 times, according to Clarivate Analytics’ Web of Science.
Five journals published by a prominent cancer research society have retracted a total of 10 papers — most of them by a former researcher at the MD Anderson Cancer Center in Houston.
Nine of the 10 retractions share that researcher, Bharat Aggarwal, as an author. Aggarwal — who more than five years ago threatened to sue us for reporting on an investigation into his work — is now up to 28 retractions, and has left his post at MD Anderson. The AACR is also appending an editor’s note to eight of his other papers — but it has not explained the reason for what it acknowledges is a lag in moving on these articles.
When the journal issued expressions of concern for four papers co-authored by José Ignacio Rodriguez-Crespo about the allegations (which had also been raised on PubPeer), it notified his institution, the Universidad Complutense de Madrid (UCM). The newly issued correction notices explain that UCM investigated the four papers, and the data support the results and conclusions. In two cases, the authors supplied the original data, and in the others, they replicated the experiments.
Rodriguez-Crespo declined to comment, saying only that the journal
In a new preprint posted to bioRxiv, image sleuths scanned hundreds of papers published over a seven-year period in Molecular and Cellular Biology (MCB), published by the American Society for Microbiology (ASM). The researchers — Arturo Casadevall of Johns Hopkins University, Elisabeth Bik of uBiome, Ferric Fang of the University of Washington (also on the board of directors of our parent non-profit organization), Roger Davis of the University of Massachusetts (and former MCB editor), and Amy Kullas, ASM’s publication ethics manager — found 59 potentially problematic papers, of which five were retracted. Extrapolating from these findings and those of another paper that scanned duplication rates, the researchers propose that tens of thousands of papers might need to be purged from the literature. That 35,000 figure is double the amount of retractions we’ve tallied so far in our database, which goes back to the 1970s. We spoke with the authors about their findings — and how to prevent bad images from getting published in the first place.
Retraction Watch: You found 59 potential instances of inappropriate duplication — how did you define this, and validate that the images were problematic?
A leading orthodontics journal has retracted 12 papers after determining that they contained either reused images, questionable data or both. Several of the articles involved experiments conducted in dogs — and one person familiar with the case told us that the duplication was an attempt to avoid sacrificing more animals than necessary for the research.
Although the list of authors on the articles varies, the common denominator is Jose Luis Calvo-Guirado, of the UCAM Universidad Católica San Antonio de Murcia, in Spain. Calvo-Guirado’s title at the institution is director de la Cátedra Internacional de Investigación en Odontología, which Google translates as director of the International Research Chair in Dentistry. Calvo-Guirado also holds (or has held) a research professorship at SUNY Stony Brook in the Department of Prosthodontics and Digital Medicine, according to his CV.
Calvo-Guirado’s name is on at least 187 entries in PubMed. Of those, 40 appeared in Clinical Oral Implants Research, a Wiley title on whose editorial board the researcher served, according to his CV.
A university and medical center have requested a batch of retractions following an investigation that found 20 papers by a cancer researcher contained manipulated images.
The request, from University of Alabama, Birmingham (UAB) and Birmingham VA Medical Center, focuses on papers by Santosh Katiyar, who explored alternative approaches to treating skin cancer in animal models.
A researcher who has received millions in funding from the U.S. National Institutes of Health and who runs a lab at the Icahn School of Medicine at Mount Sinai in New York has confessed to falsifying data in a 2014 paper.
