A ewe-turn: Researchers lose sleep, and paper, over miscounted sheep

A group of Chinese cardiologists at Capital Medical University have done a quick ewe-turn, pulling a paper after mixing up both the author order and wrongly reporting how many sheep were killed in the making of this experiment.

We covered another retraction from the CMU cardiology department in September. The sheep paper was published in October.

Here’s the notice for “Mosaic tissue-engineered porcine pulmonary artery valved conduit: long-term follow-up after implantation in an ovine model”: Continue reading A ewe-turn: Researchers lose sleep, and paper, over miscounted sheep

“[A]nonymous accusation…is procedurally immoral and irresponsible,” says researcher fighting allegations

ssrnAn economist at Takming University of Science and Technology in Taiwan recently posted a preprint attempting to refute anonymous accusations that he repeated himself in critical reviews of textbooks.

From what we understand running the paper (originally in Chinese) through Google Translate, the reviews were published in Takming University’s in-house journal, Deming Journal. The editorial board received an anonymous letter on November 3 accusing Jen-Chang Liu of duplicating — aka self-plagiarizing — three of the reviews.

The editorial board provided Liu with the documents, and together with another Takming professor, Mark Yeats, he wrote a refutation of each of the accusations. It was published on December 20 on Social Science Research Network, a preprint repository for academic works.

Here’s the English abstract for “Academic Ethics: Plagiarism, Anonymous Accusation, and Self-Plagiarism”: Continue reading “[A]nonymous accusation…is procedurally immoral and irresponsible,” says researcher fighting allegations

Takeda group retracts paper after realizing “novel” compound had already been synthesized…by a colleague

BMC_CoverA group of scientists at Takeda Pharmaceutical, including vice president Yoshinori Ikeura, has lost a paper after realizing that their “novel” compound had been previously synthesized by another Takeda researcher.

The 2011 paper, published in Elsevier journal Bioorganic & Medicinal Chemistry, was the subject of a 2012 corrigendum adding two authors to the paper. The retraction appeared online in December of this year.

Seems like they didn’t add enough authors, though. Continue reading Takeda group retracts paper after realizing “novel” compound had already been synthesized…by a colleague

Water under the bridge? Hydrology journals won’t retract plagiarized papers despite university request

hydrogeology journalIn April 2014, we wrote about the case of a former hydrologist at the University of Kansas (KU), Marios Sophocleous, who had plagiarized in at least seven studies, two of which were retracted by the journal Ground Water.

At the time, we mentioned two other articles, in the Hydrogeology Journal, that appeared destined for retraction — not least because KU requested that the journal yank them. But in a rather surprising move, the journal is declining to do so, and another publication, the Journal of Hydrology, is taking the same approach.

Here’s the notice from Hydrogeology Journal editor Clifford Voss: Continue reading Water under the bridge? Hydrology journals won’t retract plagiarized papers despite university request

A paper in Food Chemistry suggesting cranberry extract has healing properties was retracted after some of the authors complained they had no idea the paper was being published.

Here’s the notice for “Phenolic composition, antioxidant properties, and endothelial cell function of red and white cranberry fruits:” Continue reading Paper on cranberries’ health benefits retracted after researcher forges authors’ names

Thalidomide paper retracted for lab error

fertstertResearchers at the University of Pittsburgh have retracted a paper on using thalidomide, which led to an estimated 10,000 birth defects by the time the drug was pulled from the market in 1961, to prevent chemo-induced sterility.

Alkylating agents, which prevent DNA replication in cells, are a commonly-used cancer treatment. Unfortunately they also damage the ovaries and testes, sometimes causing infertility. The University of Pittsburgh scientists published a paper in Elsevier journal Fertility and Sterility in 2011 that suggested thalidomide, which causes severe birth defects when used during pregnancy, might help protect ovaries during chemo.

However, according to the notice, the authors tried and failed to replicate their results. They had two separate scientists who were not authors take a look at the results; everyone agreed that the original study incorrectly reported the number of primordial follicles, the precursor to mature eggs.

Anyone want to hire an economist who retracted 16 papers for fake peer reviews?

In December, we reported that economist Khalid Zaman was losing 16 papers over faked peer reviews.

Now, Retraction Watch has learned that he left his job at COMSATS Information Technology Center in Abbottabad, Pakistan on December 26, seven days after our post. He’s now looking for a new job, including at Beaconhouse National University in Lahore, Pakistan.

We’ve gotten ahold of his application, and it’s a real treat. Here’s an excerpt: Continue reading Anyone want to hire an economist who retracted 16 papers for fake peer reviews?

Can’t spell Novartis without VART: Drug study retracted for conflict of interest, data issues

JHH(Cover).inddA major scandal in Japan over the Novartis hypertension drug valsartan has resulted in a retraction from the Journal of Human Hypertension. 

Frequent Retraction Watch subject Hiroaki Matsubara resigned his post at Kyoto Prefectural University in 2013, after his work on valsartan was shown to be riddled with data errors and undisclosed conflicts of interest.

Also that year, suspicions about Chiba University hypertension researcher Issei Komuro’s work were first raised by an anonymous blog, which detailed numerous image manipulations in the researcher’s published works. Komuro, who frequently collaborated with Matsubara, has been a senior author on a number of valsartan papers, including the now-retracted one, which reported the results of Novartis-sponsored Valsartan Amlodipine Randomized Trial in 2011 without reporting the Novartis funding.

The paper, which has been cited three times, according to Thomson Scientific’s Web of Knowledge, had already been subject to a correction in 2013Continue reading Can’t spell Novartis without VART: Drug study retracted for conflict of interest, data issues

AIDS denialism paper retracted after Jeffrey Beall draws attention to it

scirpA paper arguing that HIV does not cause AIDS has been retracted a few weeks after Jeffrey Beall, who tracks predatory publishers, called attention to it on his blog.

Here’s what Beall wrote about the paper on December 16:

The article is entitled “Basic Principles Underlying Human Physiology[1], and you don’t have to be a scientist to know that it’s junk, for it is a manifestation of AIDS denialism. The conclusion’s first paragraph says,

HIV is not etiologically involved in AIDS. It is just a common retrovirus found in AIDS conjuncturally. There is only AIDS that may not be strictly associated neither to a primary immune deficiency nor to an acquired immune deficiency. Actually, heart failure represents the causal factor of AIDS and many other “primary” immune deficiencies (p. 1821).

Now, in that article’s place, this retraction, dated December 19, appears: Continue reading AIDS denialism paper retracted after Jeffrey Beall draws attention to it

Fake peer review fells two more papers

medicineThe number of papers retracted for fake peer reviews — well in excess of 100, by our count — continues to grow.

The latest to join the list are “Rebamipide plus proton pump inhibitor versus proton pump inhibitor alone in treatment of endoscopic submucosal dissection-induced gastric ulcer: a meta-analysis of randomized controlled trials” and “Association study of TGFBR2 and miR-518 gene polymorphisms with age at natural menopause, premature ovarian failure and early menopause among Chinese Han women,” both published in 2014 in Medicine.

Here’s how both notices, signed by senior publisher Duncan A. MacRae, read: Continue reading Fake peer review fells two more papers
