Recombinant protein paper retracted for recombining others’ work

biomed research intThe Journal of Biomedicine and Biotechnology — now BioMed Research International — has retracted a 2012 paper by a group from China who seem really to have admired a related 2007 article by a team from the Scripps Research Institute — and evidently other work, as well.

Here’s the abstract of the now-retracted paper, titled “Stable Plastid Transformation for High-Level Recombinant Protein Expression: Promises and Challenges” (emphasis ours): Continue reading Recombinant protein paper retracted for recombining others’ work

Forged authorship sinks melanoma paper

ijbcbThe International Journal of Biochemistry & Cell Biology has retracted a 2013 paper by a group from China after learning that only the first author knew about the article.

The paper was titled “Construction of circular miRNA sponges targeting miR-21 or miR-221 and demonstration of their excellent anticancer effects on malignant melanoma cells,” and it was led by Yuchen Liu. Liu’s affiliations include the Institute of Dermatology and Department of Dermatology at No. 1 Hospital, part of Anhui Medical University, and the State Key Laboratory Incubation Base of Dermatology for the Ministry of National Science and Technology.

Here’s the retraction notice:

Birds of a feather: Duplication grounds migration paper

wemcoverA group of bird researchers in China has lost their article in Wetlands Ecology and Management on the migratory habits of shorebirds after the editors of the journal learned that they’d cobbled the paper together from their own previously published work.

The article by Song et. al., “Ecological stability of the shorebird stopover site in the Yalu River Estuary Wetlands, China,” had appeared online in February.

Here’s the abstract: Continue reading Birds of a feather: Duplication grounds migration paper

Which countries have the most retractions, for which reasons?

jmlaOne of the questions we often get — but are careful to answer with some version of “we don’t know because we don’t have a denominator” — is how retraction rates vary by scientific field and country. We’ve noticed that the reasons for retraction seem to vary among countries, but didn’t really have the data. A new paper in the Journal of the Medical Library Association by Kathleen Amos takes a good step toward figuring the country part out.

Amos looked at PubMed-indexed retractions from 2008 to 2012. Here’s what she found: Continue reading Which countries have the most retractions, for which reasons?

The “sins and virtues of authors span a rather colorful palette”: New editor yanks plagiarized paper

scientometricsWhat a difference a new editor can make.

Consider the case of a paper in Scientometrics that came to the attention earlier this year of Jeffrey Beall.

Beall, a research librarian and scourge of the predatory publishing world, had previously posted on his blog about his frustrations with the journal’s seeming indifference to the word theft. (He also helped bring about another plagiarism retraction we covered earlier this year.)

The article was titled “Educational reforms and internationalization of universities: evidence from major regions of the world,” and was written by a group from China and Pakistan.It has been cited just once, according to Thomson Scientific’s Web of Knowledge, by another paper in Scientometrics.

Wrong cell line leads to retraction of kidney cancer study

plosoneA group of authors in China has retracted their December 2013 paper in PLoS ONE after realizing that they’d been studying the wrong cells.

The paper, “Up-Regulation of pVHL along with Down-Regulation of HIF-1α by NDRG2 Expression Attenuates Proliferation and Invasion in Renal Cancer Cells,” came from Lei Gao, of the Fourth Military Medical University, in Xi’an, and colleagues. It purported to find that:

“Unable to dispel the doubts,” authors lose protein structure paper

ebjA suggestion: If you’re going to use the words “overestimated accuracy” in the title of your paper, you’d better make sure you aren’t guilty of the same yourself.

A group of authors in China has lost their June 2013 paper in the European Biophysics Journal because they appear to have misinterpreted their data.  The paper, “Overestimated accuracy of circular dichroism in determining protein secondary structure,” came from chemists at Fudan University in Shanghai, and purported to find that:
