A group of nutrition researchers at the University of California, Davis has retracted their paper in the International Journal of Molecular Sciences for what they describe as a botched experiment involving mixed-up cultures.
The article, titled “Dextran Sulfate Sodium Inhibits Alanine Synthesis in Caco-2 Cells,” appeared in 2011 and was retracted in February 2012, although it just came to our attention.
According to the abstract:

Hiroaki Matsubara, a leading Japanese cardiology researcher who has had three papers retracted and another five subject to expressions of concern, has resigned from Kyoto Prefectural University, according to local media.
Mainichi Shimbun reports — according to our roughest of (Google) translations — that Kyoto Prefectural University accepted Matsubara’s resignation following an investigation. That investigation — which the university had told us about last year — revealed serious problems with 27 studies.
As we noted last March: Continue reading After three retractions, five expressions of concern, cardiologist Matsubara resigns post
The Journal of Endocrinology has run a correction for a paper by Rui Curi, the Brazilian scientist whose lawyers threatened Science-Fraud.org after the site ran a number of posts critical of Curi’s work.
Here’s the notice for “Non-esterified fatty acids and human lymphocyte death: a mechanism that involves calcium release and oxidative stress”: Continue reading Another correction for Rui Curi, whose legal threats helped force shutdown of Science Fraud site
Sanjeeb K. Sahoo, of the Institute of Life Sciences in Bhubaneswar, India, has had four papers retracted from Acta Biomaterialia for what the journal is calling “highly unethical practices.”
All four notices say the same thing: Continue reading “Highly unethical practices” force four retractions for nanotech researcher
Hip International has retracted a case study for duplication. (We apologize for the partial duplication of a headline for an earlier post about this journal, which told readers that “Similar cases will be referred to retractionwatch.”)
The article was titled “Chronic intoxication with cobalt following revision total hip arthroplasty,” and it appeared online ahead of print. Cobalt toxicity associated with metal-on-metal replacement hips has been raised as a potential adverse effect from the devices.
As the notice explains:
Retraction Watch readers may recall the case of William Hamman, the United Airlines pilot who claimed to be a cardiologist until the Associated Press uncovered him in late 2010. Hamman had published at least six papers, and since the revelations has had one retraction and one erratum, by our count.
Now comes another retraction, in the Journal of Patient Safety. Here’s the (paywalled) notice, signed by journal editor Charles Denham: Continue reading Paper by fake cardiologist retracted
Rui Curi, the Brazilian scientist whose lawyers’ threats helped force the shutdown of Science-Fraud.org, has corrected another paper criticized by the site.
Here’s the correction for “Effects of moderate electrical stimulation on reactive species production by primary rat skeletal muscle cells: Cross-talk between superoxide and nitric oxide production,” in the Journal of Cellular Physiology: Continue reading Author whose lawyers threatened Science Fraud corrects another paper
The British Journal of Radiology has retracted a 2006 paper reporting a case study of an unusual primary cancer. Trouble is, their information was second-hand.
Here’s the notice for the article, titled “Primary extragonadal retroperitoneal teratoma in an adult”: Continue reading Primary tumor article retracted for, well, not being primary
A University of Minnesota social scientist who studies health disparities has retracted a study that apparently lacked ethical approval.
Here’s the notice for “Deservingness to state health services for South – South migrants: A preliminary study of Costa Rican providers’ views,” a paper in Social Science & Medicine by Kate Goldade and a colleague: Continue reading Social sciences paper retracted for lack of ethical approval
Earlier today, we reported on the withdrawal of a paper from Research Policy, an Elsevier journal. The notice didn’t give a reason, just that the “article has been withdrawn at the request of the authors and editor.”
We’ve seen a number of such opaque withdrawals from Elsevier journals, and thought it was worth some exploration. While Elsevier’s policy here on such withdrawals is clear, as it is in other matters, we take some issue with it: Continue reading Is an “article in press” “published?” A word about Elsevier’s withdrawal policy
