Blood has retracted a 2011 article by a now-deceased Stanford researcher, Holbrook Kohrt, who earlier this month lost two other papers over concerns about the whereabouts of the data.
The journal’s move comes about a week after Retraction Watch posted a story on the previous retractions, in the Journal of Clinical Investigation (JCI), of Kohrt’s work. As we noted then, Kohrt was a superstar young faculty member who died in 2016 of complications of hemophilia. He was the subject of this 2013 profile in the New York Times, which also wrote an obituary of him.
The Blood paper was titled “CD137 stimulation enhances the antilymphoma activity of anti-CD20 antibodies.” The paper has been cited 148 times, according to Clarivate Analytics’ Web of Science.
Researchers have lost a 2018 conference abstract on screening for sickle cell disease in Africa over a dispute over authorship and the lack of appropriate disclosures.
The article, “Implementation of a sickle cell disease screening initiative in Uganda with HemoTypeSC(TM),” which was presented at a 2018 conference and then appeared in Blood, described a much-touted new blood test for sickle cell trait from a company in California called Silver Lake Research.
A former cancer researcher has falsified data in 11 studies, according to the results of a investigation scheduled to be published in the Federal Register tomorrow.
The Office of Research Integrity’s findings are based on an inquiry at Virginia Commonwealth University, where Girija Dasmahapatra worked until July of this year, investigating possible therapies for cancer. The misconduct affected research funded by three grants from the National Institutes of Health. Steven Grant, a researcher at VCU, is the principal investigator on the grants, each of which total over $2 million in funding. All of the 11 affected papers will be corrected or retracted, according to the ORI notice.
Thanks to some eagle-eyed readers, we’ve been alerted to some corrections for high profile stem cell scientist Jacob Hanna that we had missed, bringing our count to one retraction and 13 errata on 10 papers.
The problems in the work range from duplications of images, to inadvertent deletions in figures, to failures by his co-authors to disclose funding sources or conflicts of interest. Hanna is the first or last author on 4 of the papers, and one of several on the rest.
First up, a correction to a Cell paper on which Hanna is the first author:
Cell biologist Jacob Hanna, the highly cited stem cell researcher currently at the Weizmann Institute of Science, has posted a long erratum for a 2005 paper in Blood for “inadvertent mistakes,” among other issues; soon after, Hanna’s team issued another erratum for a 2009 Cell Stem Cell paper.
There’s more to tell: Last month, commenters on PubPeer noticed that images from at least 10 of the research papers Hanna coauthored in seven journals — that commenters had posted on the image hosting website Imgur and linked to on PubPeer — had been deleted.
Imgur did not confirm whether these specific images had been deleted, but told Retraction Watch:
