Yogurt to be kidding me: Five articles plagiarized in one retracted paper

with one comment

After typing up 96 citations, researchers from the National Institute for Digestive Diseases, I.R.C.C.S. “S. de Bellis,” in Bari, Italy, apparently ran out of steam for the last five, earning themselves a retraction for plagiarism in a literature review of the effects of probiotics on intestinal cancer.

Here’s the notice for “Intestinal Microbiota, Probiotics and Human Gastrointestinal Cancers,” from the Journal of Gastrointestinal Cancer: Read the rest of this entry »

Rice researcher in ethics scrape threatens journal with lawsuit over coming retraction

with 6 comments

Guangwen Tang, a rice researcher at Tufts University, landed in hot water in 2012 after her team was accused of feeding Chinese children genetically modified Golden Rice without having obtained informed consent from the parents.

Now, she’s suing both Tufts and the American Journal of Clinical Nutrition, which reportedly is retracting a paper, “ß-carotene in Golden Rice is as good as p-carotene in oil at providing vitamin A to children,” based on the federally funded research, claiming that the retraction would constitute defamation. (That retraction hasn’t happened yet.)

This isn’t the first time we’ve heard the retraction = defamation line. Readers might remember Ariel Fernandez, who threatened to sue us for writing about an expression of concern. Maybe a course on the Streisand Effect should be mandatory for PhD students?

Author squabble sinks cardiology papers

with one comment

Two papers on “novel techniques” have been retracted with what is unfortunately a very non-novel technique: an odd notice and silence when we asked for comment.

Here’s the explanation for retraction of “A novel approach to treat residual peridevice leakage after left-atrial appendage closure,” by Wunderlich N, Wilson N, and Sievert H: Read the rest of this entry »

Wayward “contractor” prompts expression of concern for PLoS ONE paper on cancer cells

with 8 comments

logoThe editors of PLoS ONE have issued an Expression of Concern (which seems likely to become a retraction) for a 2014 paper by a group of researchers in China who claim to have been led astray by a contractor hired to “edit the language” of the report.

The article, “Arsenic Sulfide Promotes Apoptosis in Retinoid Acid Resistant Human Acute Promyelocytic Leukemic NB4-R1 Cells through Downregulation of SET Protein,” came from a group in the Department of Hematology at the First Affiliated Hospital at Xi’an Jiaotong University, and was led by Yuwang Tian, a pathologist at the General Hospital of Beijing Military Area of PLA.

Or at least that’s what the manuscript eventually said. According to the expression of concern, however, that’s not what it said initially: Read the rest of this entry »

Alleged Medicare cheat loses paper for data mix-up

leave a comment »

A Boston doctor indicted on charges of Medicare fraud in 2007 has had a paper relating to the case retracted this month.

Abdul Razzaque Ahmed was considered something of a miracle worker by his patients, treating two rare and disfiguring skin conditions called pemphigoid and pemphigus vulgaris. He used more powerful medicines than the typical course of treatment, including a drug normally used to treat cancer.

The initial indictment stated that Ahmed mixed blood samples to falsely show a “dual diagnosis” of both diseases, and prove to Medicare that they required the more rigorous (and expensive) treatment. It also alleged that he profited massively from the government pay-outs. He was convicted of obstruction in 2007; the other charges were dropped when he agreed to forfeit assets worth $2.9 million.

Now, a 2001 paper by Ahmed, which claimed fifteen patients had a dual diagnosis, has been retracted because the samples were all mixed. Here is the retraction notice from Clinical Immunology: Read the rest of this entry »
