“Lack of experience and understanding” forces duplication retractions of liver cancer paper

with one comment

dovelogoA group of researchers in China has lost their paper on liver cancer after the first author admitted to duplication, also known, inelegantly, as self-plagiarism.

The paper, “Glycyrrhetinic acid-modified chitosan nanoparticles enhanced the effect of 5-fluorouracil in murine liver cancer model via regulatory T-cells,” appeared in the July 2013 issue of the Journal of Drug Design, Development and Therapy, a Dove Press title.

Patient mix-up sinks prenatal supplement paper

with one comment

This one seems like an honest mistake: a paper on dietary supplements during pregnancy has been retracted based on an error in data recording.

In the BMC Pregnancy & Childbirth paper, “Folic acid supplementation, dietary folate intake during pregnancy and risk for spontaneous preterm delivery: a prospective observational cohort study,” women for whom the researchers had no data on folic acid supplementation were classified as taking no supplements. Despite the error, the authors claim the overall conclusion remains the same: taking folic acid supplements didn’t protect women from preterm deliveries.

Here’s the retraction notice: Read the rest of this entry »

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 »
