Japanese universities find pair of researchers guilty of misconduct in 19 papers

Kenji Okajima

We have an update in the case of two Japanese scientists who first came to our attention when they retracted a 13-year-old paper in the Journal of Neuroscience last year. Shortly after that, we learned, thanks to a report in Sankei Shimbun and a helpful Retraction Watch reader, that some 17 papers were being investigated.

It now appears that 19 papers by the two researchers, Kenji Okajima and Naoki Harada, ended up under scrutiny.

Nagoya City University said last week that their investigation had concluded that Okajima and Harada committed misconduct. The university dismissed Harada, whom they found guilty of misconduct in at least eight of the papers. The investigation couldn’t find any evidence that Okajima was directly involved, but suspended him for six months because he supervised the work.

Hold the broccoli, garlic, and wine: Three Dipak Das retractions appear in Journal of Agricultural and Food Chemistry

The Journal of Agricultural and Food Chemistry has retracted three papers by Dipak Das, the resveratrol researcher found to have committed more than 100 counts of fraud by the University of Connecticut.

Journal editor James Seiber writes: Continue reading Hold the broccoli, garlic, and wine: Three Dipak Das retractions appear in Journal of Agricultural and Food Chemistry

Update on Fujii: Anesthesia journal finds overwhelming statistical evidence of data fabrication

There’s a bit more this afternoon on the story of Yoshitaka Fujii, the Japanese anesthesiologist accused of fraud and other misconduct that we reported on yesterday.

The British journal Anaesthesia, which has been looking into Fujii’s research record, has posted four articles and editorials about the case and related issues on its website. One in particular is remarkable for its conclusions. Written by a UK anesthesiologist named John Carlisle, the article claims to have analyzed 169 randomized controlled trials that Fujii conducted between 1991 and 2011.

According to the abstract (which we formatted for readability, and which should be online shortly, we’re told): Continue reading Update on Fujii: Anesthesia journal finds overwhelming statistical evidence of data fabrication

ORI: Former SUNY Upstate neuroscience dept. chair Miller manipulated data in four grant applications

Last month, we reported on two retractions by the former neuroscience and physiology department chair at the State University of New York (SUNY) Upstate Medical University in Syracuse. Both of the retractions were requested by the university after an investigation found that Michael W. Miller had committed misconduct.

Now, the Office of Research Integrity (ORI), which reviews misconduct investigations by NIH grantee institutions, has weighed in. As detailed in the Federal Register, ORI found that Miller falsified or fabricated data in four NIH grant applications, the two published (and now retracted) papers, and one manuscript submitted to the Proceedings of the National Academy of Sciences (PNAS). For example, he Continue reading ORI: Former SUNY Upstate neuroscience dept. chair Miller manipulated data in four grant applications

MD Anderson investigating researcher Bharat Aggarwal over images

Bharat Aggarwal, an influential MD Anderson researcher who has been accused in the blogosphere of manipulating images in a slew of published studies, acknowledged to Retraction Watch that the Houston institution is investigating the matter. Reached by Retraction Watch by phone at his office, Aggarwal said MD Anderson

has been looking into it and I think that they will tell everybody what it is all about. I think that somebody out there is putting this whole thing together and their mind is made up.

However, Aggarwal, chief of the center’s cytokine research section, denied that any retractions of his papers were forthcoming. He refused to comment on whether officials had confiscated his computer, as a commenter to this blog has claimed. Continue reading MD Anderson investigating researcher Bharat Aggarwal over images

Second retraction for former SUNY Upstate department chair found guilty of misconduct

Last week, we covered the case of Michael W. Miller, a former department chair at the State University of New York (SUNY) Upstate who was forced to retract a paper in the Journal of Neurochemistry after a university investigation found he had committed misconduct.

We figured more retractions might be on the way, so we weren’t surprised when a commenter informed us earlier today of “very interesting and odd retraction letter.” Miller has had at least one other retraction, it turns out, this one in Developmental Neuroscience for 2009’s “Lability of Neuronal Lineage Decisions Is Revealed by Acute Exposures to Ethanol.” Here’s the notice, published online on January 19: Continue reading Second retraction for former SUNY Upstate department chair found guilty of misconduct

University of Perugia researcher faces trial for embezzlement, fraud following 13 retractions and Expressions of Concern

Stefano Fiorucci, a gastroenterology researcher at the University of Perugia in Italy, has been indicted for fraud and embezzlement, after a university investigation found that he had manipulated images in papers that he used to win about 2 million Euros in grant funding.

The case, which has so far resulted in four retractions and nine Expressions of Concern, has dragged on for several years. The trial is scheduled for July. It’s the first time that embezzlement charges have been brought against a scientist found to have committed fraud, according to reports in Umbria 24 and the Umbria Journal.

Fiorucci’s attorney, Stefano Bagianti, told Umbria 24 that there was Continue reading University of Perugia researcher faces trial for embezzlement, fraud following 13 retractions and Expressions of Concern

Journal of Neurochemistry retracts paper after SUNY Upstate medical school finds evidence of fraud

Following an investigation by the State University of New York (SUNY) Upstate into the work of one of its neuroscientists, the Journal of Neurochemistry has retracted a 2007 paper.

The retraction notice is quite clear about why the paper is being withdrawn: Continue reading Journal of Neurochemistry retracts paper after SUNY Upstate medical school finds evidence of fraud

ORI roundup: Former SUNY grad student, two Kansas U researchers hit with sanctions

In two unrelated cases, the Office of Research Integrity (ORI) has sanctioned a grad student and a pair of colleagues, one of whom plagiarized and the other allowed the intellectual theft to go unchecked.

We think the handling of these cases — both first noted briefly by The Chronicle of Higher Education — is worth noting.

So how peripheral was Dipak Das’ resveratrol work, really?

In the wake of the massive allegations of fraud by resveratrol researcher Dipak Das, other researchers in the field are clearly trying to distance themselves from the University of Connecticut scientist. Nir Barzilai told us yesterday, for example, that despite Das seemingly’ impressive publication record, “Rome was not built on Dr. Das.”

Harvard’s David Sinclair went further, telling The New York Times that he didn’t know who Das was: Continue reading So how peripheral was Dipak Das’ resveratrol work, really?
