A third retraction stemming from Cardiff investigations

leave a comment »

cancer research 1113We’ve been reporting on retractions of research published by Cardiff University scientists following an investigation into their work. On Monday, we noted a new retraction of work by the group in Cancer Research, which we thought was the second retraction following one in the Journal of Immunology in 2011. But it turns out there was another retraction published at the same time in the same journal, which we now know about thanks to commenter David Hardman and PubPeer.

Second retraction stemming from Cardiff investigations appears

with 6 comments

cancer research 1113A second retraction of a paper by a Cardiff University researcher found to have committed misconduct has appeared.

In April, a Cardiff investigation found that Rossen Donev, a former researcher at the university, had manipulated images in four different papers. Donev, who was at the University of Swansea until August, according to his LinkedIn profile, and is now director of Biomed Consult Ltd., had already retracted a Journal of Immunology paper in late 2011 after a different Cardiff investigation.

The investigation cleared co-author and dean Paul Morgan of misconduct. Morgan resigned from Cardiff in August, but “he categorically denied that his decision had anything to do with the misconduct investigation,” according to Times Higher Education.

Here’s the new notice, from Cancer Research: Read the rest of this entry »

Two detailed retraction notices correct the cardiology record

with 4 comments

jaccTwo American College of Cardiology conference abstracts published earlier this year in the Journal of the American College of Cardiology (JACC) have been retracted, one because the authors were actually measuring something other than what they reported, and the other because newer software invalidated the results.

Here’s the notice for “Worsening of Pre-Existing Valvulopathy With A New Obesity Drug Lorcaserin, A Selective 5-Hydroxytryptamine 2C Receptor Agonist: A Meta-Analysis of Randomized Controlled Trials” by Hemang B. Panchal, Parthav Patel, Brijal Patel, Rakeshkumar Patel, and Henry Philip of East Tennessee State University: Read the rest of this entry »

Data artifact claims two fruit fly papers from leading UK group — who offer model response

with 4 comments

jcbcoverA team of researchers led by Daniel St. Johnston, director of the Gurdon Institute at Cambridge and a prominent developmental biologist in the UK, has lost a pair of articles after finding that their data were unreliable. But rather than “correct” the record with subsequent papers, they’ve withdrawn the problematic work.

To our mind, this is a poster case of doing the right thing by science. We think the notices — as provided by the authors and reported by the journals — pretty much say it all, so we’ll let them speak for themselves, followed by some details St. Johnston shared with us.

The first article, “LKB1 and AMPK maintain epithelial cell polarity under energetic stress,” appeared in 2007 in the Journal of Cell Biology and has been cited 108 times, according to Thomson Scientific’s Web of Knowledge.

According to the retraction notice:

Sir, that’s not my colon: Journal has a bite of a chicken and egg problem

with 2 comments

Case report: An 85-year-old man eats some chicken and unknowingly swallows a bone. After two days of worsening abdominal pain, he shows up to the emergency room. A CT scan reveals the bone perforating his colon. He is rushed to surgery, which is successful. Then, during his otherwise uneventful recovery, he develops female breasts.

That’s not exactly the case report that showed up in the International Journal of Surgical Case Reports earlier this month, but then again, the images in the relevant case report aren’t exactly of someone’s colon, either.

With a warning that the clinical images below are mildly NSFW, here’s Figure 1 from the cleverly titled “Chicken or the leg: Sigmoid colon perforation by ingested poultry fibula proximal to an occult malignancy:” Read the rest of this entry »
