Ovarian transplant update: Authors of 2004 live-birth follow-up letter ask Lancet to retract it

Yesterday, we brought you news of a story in Belgium involving questions about whether a woman who gave birth following an ovarian transplant could have become pregnant without the transplant. The case, which led to a university investigation but no retraction, included allegations of theft and arson.

This morning, we were made aware of a request for a retraction from The Lancet related to other work by Jacques Donnez, the obstetrician-gynecologist at the center of the case. In 2004, Donnez and colleagues published what they said was the first pregnancy using frozen banked ovarian tissue in The Lancet. The paper has been cited hundreds of times, but not everyone agreed with Donnez et al’s assessment at the time. All but one of the authors of a Lancet letter — colleagues of Donnez’s at the Catholic University of Louvain — describing the perinatal follow-up of the woman now say they don’t either, and want to retract their letter.

In their letter requesting retraction, published in the journal on July 14, Corinne Hubinont and colleagues write that they “did not have access to the patient’s gynaecological records throughout the pregnancy,” but that “Recently, we had the opportunity to read the patient’s notes,” which include a progesterone measurement “omitted by Donnez and colleagues:” Continue reading Ovarian transplant update: Authors of 2004 live-birth follow-up letter ask Lancet to retract it

Chinese mathematician forced to retract paper after two co-authors say they had nothing to do with work

A mathematician will be performing subtraction on his CV now that he has had to retract a 2011 paper because his co-authors never agreed to submit it with him.

Kewen Zhao, of Qiongzhou University, Sanya, China, has lost a paper in Discrete Applied Mathematics, a journal for which Zhao claims to review. (Given the circumstances, perhaps he meant Indiscreet Applied Mathematics.)

According to the notice: Continue reading Chinese mathematician forced to retract paper after two co-authors say they had nothing to do with work

What happens when a correction is retracted?

Seyed Rasoul Mousavi, assistant professor in the department of electrical and computer engineering at the Isfahan University of Technology in Khomeynīshahr, Iran, has been working on a way to help biologists assemble genomes with as little information as possible.

Last year, Mousavi submitted a manuscript to the Journal of Theoretical Biology, received acceptance after peer review, and got proofs back to edit.

For technical reasons, Mousavi says his corrections didn’t make it into the final article published on Jan. 12, so the publishers issued a separate corrigendum with the editorial changes. Then, on Feb. 8, the publishers retracted the corrigendum that accompanied the original article. The retraction of the corrigendum reads: Continue reading What happens when a correction is retracted?

Two retractions in biophysics journal, one because article is “too preliminary and potentially misleading”

We’ve seen vigorous debates here on Retraction Watch about when studies should be retracted. Does it require fraud? Just not being reproducible? Somewhere in between?

Given the apparent divergence of opinions on the issue, we thought it would be worth highlighting a case that involves language we haven’t seen before. Here’s the notice for “Apoptosis of CT26 colorectal cancer cells induced by Clostridium difficile toxin A stimulates potent anti-tumor immunity,” which originally appeared online in Biochemical and Biophysical Research Communications in April: Continue reading Two retractions in biophysics journal, one because article is “too preliminary and potentially misleading”

Another retraction for grad student who specializes in plagiarism and forging co-authors’ names

We have an update on the case of Moêz Smiri, a graduate student working in a Tunisian-French laboratory, whose bold method of bulking up his CV  proved a bit trop ambitieux. 

As we reported back in August 2011, Smiri had plagiarized repeatedly from previously-published work, and forged the names of co-authors, in a 2010 article in Plant Science on the effects of cadmium on peas. That article was one of at least six papers on which Smiri appeared as first author — a pretty impressive output for a young researcher.

Among the list was article in Ecotoxicology and Environmental Safety, “Effect of cadmium on resumption of respiration in cotyledons of germinating pea seeds.” That paper is now retracted. According to the notice: Continue reading Another retraction for grad student who specializes in plagiarism and forging co-authors’ names

Three papers by German management prof retracted for duplication, statistical issues

Ulrich Lichtenthaler, a management professor in Germany, has had three papers retracted by two different journals, after readers noticed statistical irregularities.

Lichtenthaler was at the WHU – Otto Beisheim School of Management when he published the papers in 2009 and 2010. He is now at the University of Mannheim. The retraction in Strategic Organization was first reported by the Strategy Profs blog. It reads: Continue reading Three papers by German management prof retracted for duplication, statistical issues

Group retracts microRNA paper after realizing reagent was skewing results

A retraction from a high-profile group uncovered a technical limitation involving a widely used reagent.

Some quick background: the sequence hypothesis central hypothesis dogma of biology states that DNA gets transcribed to RNA that gets translated into proteins. Some RNAs, however, don’t code for proteins, but instead help to regulate gene expression. These microRNAs are tiny in size, but can regulate gene expression across animal and plant kingdoms.

In September 2011, the Molecular Cell published an entire issue with regulatory RNA as its theme. V. Narry Kim, associate professor at Seoul National University and high-profile microRNA researcher contributed a study that her group has now retracted just months later on June 29.

The problem? A reagent used to purify miRNAs favors some miRNAs and fails to isolate those rich low in guanine and cytosine — two of the four building blocks of RNA — or those with few secondary folding structures.

University of Michigan psychologist resigns following concerns by statistical sleuth Simonsohn: Nature

A second psychology researcher has resigned after statistical scrutiny of his papers by another psychologist revealed data that was too good to be true.

Ed Yong, writing in Nature, reports that Lawrence Sanna, most recently of the University of Michigan, left his post at the end of May. That was several months after Uri Simonsohn, a University of Pennsylvania psychology researcher, presented Sanna, his co-authors, and Sanna’s former institution, the University of North Carolina, Chapel Hill, with evidence of “odd statistical patterns.”

Simonsohn is the researcher who also forced an investigation into the work of Dirk Smeesters, who resigned last month. Last week, Yong reported that Simonsohn had uncovered another case that hadn’t been made official yet.

According to today’s story, Sanna has asked the editor of the Journal of Experimental Social Psychology — which is also retracting one of Smeesters’ papers — to retract three papers published from 2009 to 2011. These are the three he seems to have published there during that time: Continue reading University of Michigan psychologist resigns following concerns by statistical sleuth Simonsohn: Nature

Elsevier parasitology journal retracts paper after finding author made up peer reviewer email addresses

Note to authors: If a journal asks you to suggest reviewers for your submitted manuscript, don’t thank them by faking the reviewer’s emails.

You might just get caught.

That’s what happened recently at Experimental Parasitology, according to the retraction notice for “Entamoeba histolytica: Cloning, expression and evaluation of the efficacy of a recombinant amebiasis cysteine proteinase gene (ACP1) antigen in minipig:” Continue reading Elsevier parasitology journal retracts paper after finding author made up peer reviewer email addresses

Pulp fiction: doubtful “veracity” leads to retraction of endodontics paper

This one’s like taking candy from a baby.

The Journal of Endodontics — or JOE — has retracted a 2011 article (its online date) on the prospects of tissue engineering for the mouth by a group of Chinese authors who appear to have tried to pass bogus data into print.

The paper was titled “Mineralized Tissue Formation by Bone Morphogenetic Protein-7–transfected Pulp Stem Cells“. According to the notice: Continue reading Pulp fiction: doubtful “veracity” leads to retraction of endodontics paper
