Cell update: Co-corresponding author let go from Belgian university; retraction notice language changed
We’ve learned more about the circumstances behind a Cell retraction that we covered last week.
First, one of the two corresponding authors left the institution where he most recently worked. Belgium’s VIB Ghent told us that Pankaj Dhonukshe was no longer employed there and said: Read the rest of this entry »
The journal Applied Surface Science (okay, so maybe it’s not called ASS at the home office) is retracting a pair of articles in its December issue.
The first, “Structure and mechanical properties of Ni–P electrodeposited coatings,” appeared in 2009 and was written by a group of researchers in Beijing. It has been cited nine times, according to Thomson Scientific’s Web of Knowledge. Its problem: Plagiarism. According to the retraction notice: Read the rest of this entry »
Last week, we reported on a retraction in the Journal of Analytical Atomic Spectrometry that left us a bit puzzled. The notice referred to a problem with “the way the data was presented,” but the authors told us this was just an error picked up in proofreading, somehow after the paper had been published online.
We now have much more of the story. The Royal Society of Chemistry’s May Copsey, who edits the journal, tells Retraction Watch: Read the rest of this entry »
We have a fourth retraction in the Journal of Biochemistry for Naohito Aoki, a Japanese researcher and former postdoc in a German lab, whose images have been called into question but whose retraction notices were scant. In this case, however, the journal, while not exactly overbrimming with information about the article, at least gives us some sense of what’s going on.
Aoki worked in the lab of Axel Ullrich, of the Max Planck Institute of Biochemistry, and appeared on two retracted articles in the Journal of Biological Chemistry (JBC) with his mentor, along with a third with a co-author from Japan, Tsukasa Matsuda. Although those notices don’t say anything about the reason for the retractions — this was before the JBC started providing such information — Ulrich told us that Aoki had been manipulating images.

The Lancet has retracted a study of Novartis’ blood pressure drug valsartan (Diovan) that has been subject to an investigation following the retraction of a related study earlier this year.
Here’s the detailed notice for “Valsartan in a Japanese population with hypertension and other cardiovascular disease (Jikei Heart Study): a randomised, open-label, blinded endpoint morbidity-mortality study”: Read the rest of this entry »
The University of Tokyo panel investigating the work of a former professor there, Shigeaki Kato, has recommended the retraction of 43 of his group’s articles, according to a report in the Asahi Shimbun newspaper.
If the papers are indeed retracted, Kato, who already has at least five articles subject to an expression of concern and five retractions, would be fifth on the list of most retractions for a single author, by our unofficial tally. His fellow countryman, Yoshitaka Fujii, continues to hold the lead at what appears to be 183, followed by Joachim Boldt (~89), John Darsee (~83), and Diederik Stapel, at 53. [See note at end.]
The Asahi report quotes Kato — who has received some $20 million in government funding for his work — as acknowledging problems with the data in his studies: Read the rest of this entry »
