Ob-gyn journal pulls pregnancy test paper for undeclared conflict of interest, other problems

The American Journal of Obstetrics and Gynecology (AJOG) as a remarkable retraction notice in its November issue — the likes of which we haven’t seen before.

A little background: Earlier this year, Laurence Cole, an academic obstetrics specialist at the University of New Mexico in Albuquerque, published a paper in the AJOG looking at the wide variability in the hormone human chorionic gonadotropin, or hCG, during pregnancy (we’d link to the article, but the journal has pulled it, so here’s the abstract on Medline).

Cole runs — or did run until recently, more on that in a moment — the USA hCG Reference Service at the university, which purports to be the only lab in the world that can measure all forms of hCG. He has published extensively in this area of research, with at least 125 papers to his name on the subject, according to a Medline search. One of his websites puts the figure at 246.

So Cole was definitely a known quantity to the journal editors when he submitted his manuscript and when it was published online in February of this year. That’ll be more important in a bit. But first, the retraction notice: Continue reading Ob-gyn journal pulls pregnancy test paper for undeclared conflict of interest, other problems

Florida group loses second hypertension paper, but retraction notice stays mum on why

We’ve obviously gotten plenty of mileage out of our conversation last January with L. Henry Edmunds, the grumpypants editor of the Annals of Thoracic Surgery who told us that the reason behind an opaque retraction notice in his journal was “none of  [our] damn business.”

Still makes us chuckle.

That episode came to mind recently when we learned of a new retraction, this one in the journal Perfusion, involving the same lead researcher, anesthesiologist Felipe Urdaneta, whose work Edmunds had pulled. Continue reading Florida group loses second hypertension paper, but retraction notice stays mum on why

A flying what? Symbiosis retracts paper claiming new species arise from accidental mating

In 2009, Donald Williamson made what many biologists said was an extraordinary claim: The reason caterpillars become butterflies is that two different species accidentally mated with one another. As Brendan Borrell explained at the time in Scientific American: Continue reading A flying what? Symbiosis retracts paper claiming new species arise from accidental mating

A retraction as a group’s papers on smoking and weight loss are too close for comfort

The American Journal of Physiology Endocrinology and Metabolism is retracting a 2009 article by Japanese researchers who appeared to be so fond of their data they published them thrice.

The paper, “Dual suppression of adipogenesis by cigarette smoke through activation of the aryl hydrocarbon receptor and induction of endoplasmic reticulum stress,” by Masanori Kitamura and colleagues, looked at the biochemical mechanism by which cigarette smokers seem to be able to keep weight off. It has been cited eight times, according to Thomson Scientific’s Web of Knowledge.

But according to the retraction notice: Continue reading A retraction as a group’s papers on smoking and weight loss are too close for comfort

Retracted retraction leaves Genomics paper intact — but authors wonder if anyone will know

Last March, the journal Genomics retracted a paper, “Discovery of transcriptional regulators and signaling pathways in the developing pituitary gland by bioinformatic and genomic approaches,” for reasons that don’t really fit into a tight lede sentence. Let’s just say that at times the problems involved both questions of authorship and the validity of the research. More on all that in a moment.

Meanwhile, things change. Now the journal, an Elsevier title, is un-retracting (that can’t be a real word, can it?) the retraction. You’d think that would please the authors, and it does to an extent. But they also wonder, legitimately, whether the original retraction will refuse to relinquish its grip on the resurrected article and consign it to database oblivion.

First, some background. Continue reading Retracted retraction leaves Genomics paper intact — but authors wonder if anyone will know

Remaining Zhiguo Wang retractions will be in the Journal of Cellular Physiology

We’ve been following the case of Zhiguo Wang, the former Montreal Heart Institute researcher who was forced to resign his post in early September following an investigation into his work. At the time of that announcement, two retractions of the Wang group’s papers — which we had reported on in August — had appeared. The Institute said they had requested three more.

We figured that meant a total of five, although the Institute wouldn’t say which they were. So when we found out about a third retraction, in the Journal of Cell Science, we said it was the first of the remaining three.

We were wrong. Continue reading Remaining Zhiguo Wang retractions will be in the Journal of Cellular Physiology

Can appendicitis be treated with antibiotics? Retraction muddies the waters

The Journal of Gastrointestinal Surgery has retracted a 2009 article for plagiarism, but it almost seems like the editors were looking for any excuse to bail out on the troubled paper.

The article, “Conservative management of acute appendicitis,” by two researchers from Kashmir, India, purported to show that antibiotics might be a safe, surgery-sparing approach to appendicitis in some patients. The study has been cited 14 times by other papers, according to Thomson Scientific’s Web of Knowedge. It was also cited in a Consumer Reports article as evidence that as many as 10% of patients “get better without treatment” — a curious interpretation of the data.

But in February 2010, a group of surgeons from Bologna, Italy, challenged the Indian authors in a letter to the journal. The authors expressed interest in the concept, which they said had “significant clinical implications,” but took issue with the methodology of the study: Continue reading Can appendicitis be treated with antibiotics?

ExpungedBob? Algae journal pulls phytoplankton paper with unwitting co-author

While looking at a recent retraction notice in the Journal of Phycology, the one of us with small children at home couldn’t help but imagine a conversation between cartoon character SpongeBob and his nemesis, Plankton:

SpongeBob: You used me … for land development! That wasn’t nice.

Sheldon J. Plankton: Haven’t you figured it out, SpongeBob? Nice guys finish last. Only aggressive people conquer the world. Ha ha ha ha!

SpongeBob: Well … what about aggressively nice people?

Who knew the world of phytoplankton could be so cutthroat? (Spoiler alert: we did.)

Consider: The Journal of Phycology — phycology is the study of algae and related organisms — is retracting a paper after learning that one of the three co-authors, well, wasn’t. Cyanobacteria may be the oldest known life form on earth, but the hyper-ambitious aren’t far behind.

Here’s the notice: Continue reading ExpungedBob? Algae journal pulls phytoplankton paper with unwitting co-author

That’s a Mori! Seven more retractions brings latest count to 30

The other day we reported that Naoki Mori had lost his 23rd paper to retraction for image manipulation and duplication. Turns out we were wrong by a pretty wide margin.

The International Journal of Cancer has retracted seven more articles by the disgraced Japanese researcher, all for the same reasons:

The following article has been retracted through agreement between the first author and several coauthors, the journal Editor in-Chief, Peter Lichter, and John Wiley & Sons, Ltd. … After an investigation the retraction has been agreed due to inappropriate duplication of images and overlap with other published work.

The papers are as follows: Continue reading That’s a Mori! Seven more retractions brings latest count to 30

Another retraction for Naoki Mori (make that 23?)

The retraction total for Naoki Mori continues to rise.

The October issue of Biochemical and Biophysical Research Communications has retracted a 2007 paper by Mori et al for the same issues — manipulated images — that  brought down the 20-odd other papers of his since the scandal broke in late December.

Here’s the notice for the pulled paper, titled “Downregulation of citrin, a mitochondrial AGC, is associated with apoptosis of hepatocytes:” Continue reading Another retraction for Naoki Mori (make that 23?)
