Clinical Endoscopy retracts sedation paper, creates neologism in process

Clinical Endoscopy, the official journal of the Korean Society of Gastrointestinal Endoscopy, has retracted a 2011 paper on sedation practices.

Although the retraction statement is underpowered for information, it has a charming neologism. To wit, the announcement for the paper, “Comparison of midazolam alone versus midazolam plus propofol during endoscopic submucosal dissection,” is a “noticement.”

Unfortunately, that’s about all that’s interesting about this retraction. Or rather, that’s the only thing on which we can comment, given the notice itself:

Korean stem cell investigation expands to another researcher, and more papers

Last month, we brought you the story of Soo-Kyung Kang, a Seoul National University stem cell researcher who has now retracted four papers amidst questions about image manipulation in a total of 14 studies. That story has drawn a great deal of attention in Korea, with comparisons to the Woo-Suk Hwang scandal, and has even led to a profile of Retraction Watch in the Seoul Daily, one of Korea’s largest newspapers.

We’ve now learned that the investigation has grown to 25 papers after an anonymous whistleblower warned about possible data fabrications in another paper by Kang, an associate professor of veterinary biotechnology, and Kyung-Sun Kang, director of the Adult Stem Cell Research Center in the same department (but no relation). And Soo-Kyung Kang was investigated in 2010, according to the Korea Herald.

The researchers’ labs are also under lockdown Continue reading Korean stem cell investigation expands to another researcher, and more papers

Authors retract 2010 Archives of Otolaryngology-Head and Neck Surgery paper because of duplication

The authors of a 2010 paper in the Archives of Otolaryngology-Head and Neck Surgery have retracted it after realizing that their colleagues at other institutions had already published a paper based on the same findings.

Here’s the retraction notice: Continue reading Authors retract 2010 Archives of Otolaryngology-Head and Neck Surgery paper because of duplication

Whistleblower forces retractions of four stem cell papers amid questions about more than a dozen studies

In a case that is a good reminder of why journal editors shouldn’t ignore anonymous tips, a Seoul National University stem cell researcher has been forced to retract four papers, and withdraw another under peer review, in Antioxidants & Redox Signaling following a whistleblower’s exhaustive analysis.

Two retractions by Soo Kyung Kang, a professor of veterinary biotechnology at Seoul National University, appeared on May 9 after an anonymous whistleblower sent a 70-slide PowerPoint presentation to the editors of ten journals that contained evidence of suspicious floating error bars, errors larger than actual measurements, pasted-together lanes in PCR gels and RNA and CHIP blots and several cases where the same control blot data is shown across different experiments and in different papers. In all, the whistleblower raises questions about 14 papers in the ten journals.

Here is the May 9 notice for “Nuclear Ago2/HSP60 contributes to broad spectrum of hATSCs function via Oct4 regulation”: Continue reading Whistleblower forces retractions of four stem cell papers amid questions about more than a dozen studies

Skin in the game: Derm journal retracts identical cancer case study submitted by two groups at the same facility

It seems the faculty at Myongji Hospital, in Goyang, Korea, have some ‘splainin to do.

Two groups of physicians from the hospital, part of Kwandong University College of Medicine, published case reports on a rare form of basal cell carcinoma. Turns out they were writing about the same patient.

According to a retraction notice in the Annals of Dermatology, a publication of the Korean Dermatological Association and the Korean Society for Investigative Dermatology: Continue reading Skin in the game: Derm journal retracts identical cancer case study submitted by two groups at the same facility

Redox, redux: Journal pulls paper over data problems

Antioxidants & Redox Signalling has issued much more detailed retraction notice for a paper it pulled last year that was marred by duplicate data.

As we reported then, the journal’s initial notice for the 2011 article, titled “Inhibition of LXRa-dependent steatosis and oxidative injury by liquiritigenin, a licorice flavonoid, as mediated with Nrf2 activation,” was underwhelming:

THIS WORK HAS BEEN RETRACTED BY THE AUTHORS

Although we learned at the time that a reader, Paul Brookes, of the University of Rochester, had raised concerns about the article to the editors of ARS and other publications, we were glad to see that ARS has decided to make a clean breast of matters. The study has been cited by other papers three times, according to Thomson Scientific’s Web of Knowledge.

Here’s the notice, from editor Chandan K. Sen: Continue reading Redox, redux: Journal pulls paper over data problems

Neuro journal retracts case study with redundant data

If that headline has you scratching your, well, head, we don’t blame you. After all, case studies are, by definition, unique — but not this one.

Neurological Sciences, the official journal of the Italian Society of Neurology, has retracted a 2009 article by a Korean scientist after learning that the manuscript contained elements of a 2007 publication in a different publication.

According to the notice: Continue reading Neuro journal retracts case study with redundant data

Oops! Tissue Antigens retracts paper after accidentally publishing it twice

A retraction notice from Tissue Antigens:

The following article from Tissue Antigens, A gene-specific primer extension and liquid bead array system for killer cell immunoglobulin-like receptor genotyping by H. J. Park, Y. Oh, H. J. Kang, E. J. Han, H. Y. Shin, H. S. Ahn, K. S. Ahn, B. H. Yoon & B. D. Han, published online on 14 March 2011 in Wiley Online Library (http://onlinelibrary.wiley.com) and in Tissue Antigens, 77:535–539, has been retracted by agreement between the authors, the journal Editor-in-Chief, James McCluskey, and Blackwell Publishing Ltd. The retraction has been agreed due to inadvertent publication of the same article in a prior issue of the journal: Park, H. J., Oh, Y., Kang, H. J., Han, E. J., Shin, H. Y., Ahn, H. S., Ahn, K. S., Yoon, B. H. and Han, B. D. (2011), A gene-specific primer extension and liquid bead array system for killer-cell immunoglobulin-like receptor genotyping.Tissue Antigens, 77:251–256.

Two murky retractions in Chemosphere for authorship issues

The journal Chemosphere has retracted two papers over authorship concerns. The problem is, we don’t really know what those concerns are.

Here’s one notice: Continue reading Two murky retractions in Chemosphere for authorship issues

Reason behind opaque Antioxidants & Redox Signaling retraction notice revealed

There’s an unhelpful retraction notice online in the journal Antioxidants & Redox Signaling, a Mary Ann Liebert publication. The paper, “Inhibition of LXRalpha-dependent steatosis and oxidative injury by liquiritigenin, a licorice flavonoid, as mediated with Nrf2 activation,” has been removed from the site, except for the abstract, which now has this in front of it:

THIS WORK HAS BEEN RETRACTED BY THE AUTHORS

That, as we’ve said before in exasperation, certainly clears things right up.

But we found out the reason for the retraction from Paul S. Brookes, an associate professor of anesthesiology at the University of Rochester Medical Center. Here’s the letter he sent the editors of Antioxidants & Redox Signaling and Free Radical Biology and Medicine, an Elsevier title: Continue reading Reason behind opaque Antioxidants & Redox Signaling retraction notice revealed
