Crystal myth: 11 more retractions from crystallography journal after 2010 fakery

About a year ago, Acta Crystallographica Section E issued a bombshell editorial. The journal was pulling 70 papers from two groups of researchers at the same Chinese university after discovering that the structures they reported had been fakes.

As the editorial explained, the fraud was detected during a routine review of the structures by Ton Spek, of Utrecht University in The Netherlands. According to the editorial: Continue reading Crystal myth: 11 more retractions from crystallography journal after 2010 fakery

TKO for knee replacement paper, but notice raises more questions than it answers

The journal Orthopedics is retracting a paper by Chinese researchers who appear to have been a little to hasty to submit their manuscript.

Titled “Comparison of the mini-midvastus with the mini-medial parapatellar approach in primary TKA,” the October 2010 paper purported to describe a prospective, randomized study comparing two approaches to total knee arthroplasty, or knee replacement surgery. The authors, from First Affiliated Hospital of Suzhou University, stated that “all knees were implanted with the same posterior-stabilized prosthesis by the same surgeon,” a Dr. Tang.

Having claimed to have separated the effects of the surgery from those of the prosthetic — in this case, the Genesis II device from Smith & Nephew — the authors said that the study was able to demonstrate that “the early clinical results are similar between the mini-midvastus and mini-medial parapatellar approach. The mini-medial parapatellar approach is easier to initially apply and provides better visualization for TKA.”

Except that it didn’t.  Continue reading TKO for knee replacement paper, but notice raises more questions than it answers

We wrote what? Breast cancer paper falls to rogue author

Something was fishy at China Normal University. According to the journal Anti-Cancer Drugs, a 2010 paper by researchers at the Beijing school — “3,30′-Diindolylmethane negatively regulates Cdc25A and induces a G2/M arrest by modulation of microRNA21 in human breast cancer cells” — turned out to have suffered from an unfortunate anomaly. According to the retraction notice: Continue reading We wrote what? Breast cancer paper falls to rogue author

Resurrection? Paper about Jesus and the flu remains online, not marked as retracted

In August, we reported on the retraction of a paper in Virology Journal about whether a woman allegedly cured by Jesus Christ had the flu or some other ailment. The original paper was published on July 21, 2010. On August 11, after a flurry of criticism from various bloggers, the journal’s editor, Robert Garry, apologized for publishing it in a comment. On the 13th, the journal published a retraction notice.

But as an eagle-eyed Retraction Watch reader has pointed out, the original paper, and its abstract, both remain online, without any suggestion that the paper was retracted. We found that puzzling, so we called Garry, of Tulane’s department of microbiology and immunology. Continue reading Resurrection? Paper about Jesus and the flu remains online, not marked as retracted

ME-Coli: Germ paper retracted after mentor accuses authors of idea theft

Plagiarism can involve the theft of words, and we’ve covered plenty of such cases (like this one). But here’s a case of what appears to be more wholesale lifting of everything from ideas to assays.

The Journal of Molecular Microbiology and Biotechnology (JMMB), a Karger title, has retracted an October 2010 paper, “Characterization of Methyltransferase Properties of Escherichia coli YabC Protein with an Enzyme-Coupled Colorimetric Assay,” by Jingsong Gu and Chunjiang Ye. Both of those scientists are in the department of biotechnology at the University of Jinan in China.

Gu had trained as a postdoctoral research in the laboratory of biologist Elaine Newman, of Concordia University in Montreal who describes herself as a “long time friend” of E. coli. (As they say, with friends like that, who needs enemas?)

The retraction notice — a trio of remarkably revealing letters — begins with an apologia from the authors: Continue reading ME-Coli: Germ paper retracted after mentor accuses authors of idea theft

No medals: Group that retracted JACS gold nanoparticle paper retracts silver one, too

Earlier this month, we reported that a group led by Jicun Ren, of Shanghai Jiaotong University, had retracted a paper in the Journal of the American Chemical Society (JACS) on a way to measure the concentration of gold nanoparticles. Turns out they are also retracting a very similar paper about silver nanoparticles published in the January 18, 2010 issue of Chemistry: A European Journal.

Ren tells Retraction Watch that the silver paper, “Ultrahighly sensitive homogenous detection of DNA and microRNA by using single-silver-nanoparticle counting,” is being retracted for the same reason as the gold one. From our earlier post (just substitute “silver” for “gold”): Continue reading No medals: Group that retracted JACS gold nanoparticle paper retracts silver one, too

Authors plan to appeal Global Ecology and Biogeography retraction

The authors of a Global Ecology and Biogeography study originally published in November 2009 and retracted last week are appealing the decision with the Committee on Publication Ethics (COPE), Retraction Watch has learned.

Journal of the American Chemical Society retracts gold nanoparticle paper

On October 20, the Journal of the American Chemical Society retracted a 2009 paper. The retraction notice for “Single Gold Nanoparticles Counter: An Ultrasensitive Detection Platform for One-Step Homogeneous Immunoassays and DNA Hybridization Assays” was somewhat opaque:

This article is being retracted due to inaccurate DNA hybridization detection results caused by application of an incorrect data processing method. The authors regret any confusion that may have been created by the paper’s publication.

We contacted the paper’s lead author, Jicun Ren, of the College of Chemistry and Chemical Engineering, State Key Laboratory of Metal Matrix Composites, Shanghai Jiaotong University, to ask for more detail. He responded: Continue reading Journal of the American Chemical Society retracts gold nanoparticle paper

Best of Retractions Part III: Whatever can go wrong …

Paging Dr. Murphy.

In July, the editors of Cancer Biology & Therapy published a retraction remarkable for its scope. Apparently, nearly everything dishonest authors can do to doctor a manuscript, these authors did.

The paper, “Overexpression of transketolase protein TKTL1 is associated with occurrence and progression in nasopharyngeal carcinoma,” initially appeared on the journal’s website in January 2008. It came out in print three months later, in the April issue, and has been cited 8 times since, according to Thomson Scientific’s Web of Knowledge.

The authors were Song Zhang, Jian Xin Yue,  Ju Hong Yang, Peng Cheng Cai and Wei Jia Kong, of Huazhong University of Science and Technology in Hubei, China. It will be quite clear why we listed all those authors in a moment. Continue reading Best of Retractions Part III: Whatever can go wrong …

Do plagiarism, fraud, and retractions make it more difficult to trust research from China?

Yesterday, we blogged about the retraction of a paper in the Journal of Clinical Rheumatology from a research team in China. The paper — claiming that tai chi helped women with arthritis — was riddled with inconsistencies and plagiarism.

Today, plagiarism and fraud made the front page of the New York Times.

Coincidence? Continue reading Do plagiarism, fraud, and retractions make it more difficult to trust research from China?
