The International Association for Dental Research has retracted a student travel award after discovering that the recipient had previously published the work he used to secure the grant, including in an abstract he presented at the same conference last year.
The self-plagiarism was uncovered by an anonymous group of students at the Hong Kong University dentistry school, where the student is a PhD student. The unnamed students sent both the IADR and HKU faculty members a color-coded chart showing identical phrases between the 2014 abstract, a 2013 paper published in the Journal of Periodontal Research called “Human umbilical vein endothelial cells synergize osteo/odontogenic differentiation of periodontal ligament stem cells in 3D cell sheets,” and another abstract the authors presented at the 2013 IADR conference.
The paper and both abstracts were written by P.K.C.P. Panduwawala, who lost the travel grant, along with HKU’s former dean of dentistry L.P. Samaranayake; HKU’s associate dean for research L.J. Jin; and C.F. Zhang, part of HKU’s tissue engineering group.
The IADR’s page now lists the winners with a note at the bottom: Read the rest of this entry »
The article, “The post-peak spectra in electron energy loss near edge structure,” came from a group led by one Feng Tian, a materials scientist at Shanghai University for Science and Technology. The other authors were Peter Shattschneider and Micheal Stoger-Pollach, of the Vienna University of Technology. Except that they weren’t.
Here’s the notice for “Effect of ST3GAL 4 and FUT 7 on sialyl Lewis X synthesis and multidrug resistance in human acute myeloid leukemia,” a paper initially published in June: Read the rest of this entry »
A group of researchers at the Guangdong Academy of Medical Sciences in Guangzhou, China have retracted a paper that came out of a clinical trial on transarterial chemoembolization, a targeted kind of chemotherapy.
According to the notice, one of the authors mixed up the control samples with the clinical samples, and “could not recall which samples were in the wrong group.” The paper hasn’t yet been cited, according to Thomson Scientific’s Web of Knowledge.
Here’s the notice in Medical Oncology:
Here’s the notice for “Determination of silk fibroin secondary structure by terahertz time domain spectroscopy” (free, but requires sign-in) in Analytical Methods, which is almost identical to this notice in Analyst: Read the rest of this entry »
In June, a paper in Tumor Biology was retracted for at least four reasons, including bad data and hiding a trial sponsor (Merck). Some people who contributed work weren’t cited; at least one author had no idea his name would be on it. And that’s just what they tell us in the notice.
Here’s the notice for “Neutropenia and invasive fungal infection in patients with hematological malignancies treated with chemotherapy: a multicenter, prospective, non-interventional study in China:” Read the rest of this entry »
We’ve written before about how common cell line mix ups are in cancer research; according to a 2012 Wall Street Journal article (paywalled), between a fifth and a third of cancer cell lines tested by suspicious researchers turned out to be misidentified.
Obviously, mistakenly studying the wrong kind of cancer is a waste of precious resources, both time and money. And it’s clear the problem hasn’t gone away. PLoS ONE just retracted a cancer paper originally published in December 2012 for studying two cell lines that had been contaminated by other cell types.
Sometimes publishers and authors decide it’s easier to retract a paper than leave it up for discussion by other scientists.
That seems to be the case here: The authors of a paper in Langmuir retracted it in September for a math mistake, but not before the journal refused to publish a comment criticizing the publication.
Although it shocks some observers every time, we’ve reported on the retractions of more than 100 papers pulled because authors managed to do their own peer review.
Apparently, it’s happened again.
Here’s a retraction notice in BMC Systems Biology for “Predicting new molecular targets for rhein using network pharmacology,” by Aihua Zhang, Hui Sun, Bo Yang and Xijun Wang:
A cardiology paper from China has been retracted because “permission to report these discussions was not sought nor obtained,” though it’s unclear what “the discussions” refers to. The person to whom the discussions are attributed to in the retraction, Ji Bingyang, is not an author on the paper, and none of his papers are cited in the retracted article.
