Journal retracts heart stem cell paper (and pulls no punches) over image fraud

Some retractions beg for a kick of sand in the face, and others do the kicking. Here’s an example of what Charles Atlas might have written had he been a journal editor concerned with research integrity.

Experimental Biology and Medicine, the official journal of the Society for Experimental Biology and Medicine, has retracted a 2010 article by a group of stem cell scientists in China with an unfortunate affinity for a particular figure—one they’d used in a previous publication, only with a different description.

Here’s the notice for the paper, “Isolation and characterization of multipotent progenitor cells from the human fetal aorta wall,” which was cited five times before it was retracted, according to Thomson Scientific’s Web of Knowledge: Continue reading Journal retracts heart stem cell paper (and pulls no punches) over image fraud

Plagiarism kills weed paper

The January 2012 issue of Biosystems Engineering has a commendably thorough retraction notice regarding a case of plagiarism in its pages.

The notice, regarding the article “Advanced techniques for Weed and crop identification for site specific Weed management,” by Karan Singh, K.N. Agrawal, and Ganesh C. Bora, of North Dakota State University, speaks for itself: Continue reading Plagiarism kills weed paper

Blood retracts stem cell paper from Amy Wagers’ Harvard lab after 14 months of concern

More than 14 months after Blood issued a notice of concern about a paper by a Harvard stem cell scientist and her former post-doc, the journal has retracted the article.

Here’s the notice for the paper, “Osteolineage niche cells initiate hematopoietic stem cell mobilization,” by Shane Mayack and Amy Wagers: Continue reading Blood retracts stem cell paper from Amy Wagers’ Harvard lab after 14 months of concern

Multiple retractions as brazen plagiarist victimizes orthopedics literature

Several journals in the field of orthopedics and related disciplines have been victimized by an apparent serial plagiarist.

The author, Bernardino Saccomanni, of Gabriele D’ Annunzio University, in Chieti Scalo, Italy—across the boot and up a bit from Rome—appears to have lifted significant amounts of text in several articles.

Last January, for example, Current Reviews in Musculoskeletal Medicine, a Springer title, retracted a 2010 article by Saccomanni, “Painful os intermetatarseum in athletes: a literature review of this condition is presented,” after determining that it plagiarized a 2007 article in the Archives of Orthopaedic Trauma Surgery, also from Springer, with a very similar title, “Painful os intermetatarseum in athletes: report of four cases and review of the literature.”

Osteoporosis International, another Springer publication, has retracted a 2011 paper by Saccomanni titled “Vertebroplasty: an international point of view on this “minimally invasive” surgical technique,” after evidently learning that the point of view wasn’t exactly Saccomanni’s to begin with. Continue reading Multiple retractions as brazen plagiarist victimizes orthopedics literature

Another Hattori retraction over reused figure from cardiology pub

Another paper in Diabetologia by Yoshiyuki Hattori has been retracted for image duplication, marking the second of his articles in the journal to be pulled for that reason.

The notice for the article, “A glucagon-like peptide-1 (GLP-1) analogue, liraglutide, upregulates nitric oxide production and exerts anti-inflammatory action in endothelial cells,” states: Continue reading Another Hattori retraction over reused figure from cardiology pub

Which came first? Vet journal retracts previously published chicken paper

Research in Veterinary Science has retracted a 2010 paper by Egyptian scientists who published the same article the previous year in a different journal.

Here’s the retraction notice for the paper, “Comparative biochemical studies on steroidogenic compounds in chickens,” by Mohamed O.T. Badr and Mohamed A. Hashem,  from Zagazig University and the Egyptian Ministry of Agriculture: Continue reading Which came first? Vet journal retracts previously published chicken paper

PNAS retracts two papers on osmolytes after researchers discover crucial measurement errors

A good carpenter never blames his tools. But for scientists, sometimes machines do go bad–with disastrous results. Consider the following:

The Proceedings of the National Academy of Sciences has retracted two papers by researchers in the United Kingdom and the United States after the scientists learned that their results were based largely on a problem with their highly sensitive instruments.

Heart study pulled after production glitch leads to duplicate publication

On reflection, that headline pretty much says it all. But for those readers who took the time to click on the link, here’s the rest of it.

The journal Heart, a title of the BMJ group, has retracted a paper that it published twice: Continue reading Heart study pulled after production glitch leads to duplicate publication

Lab squabble leads to retracted correction over authorship in British Journal of Haematology

Here’s a he said-he said that left one author with a publication, then nothing, and us scratching our heads.

In March 2010, the British Journal of Haematology issued a rather straightforward correction regarding a 2007 article by a group of researchers from Kansas Kansas City, Missouri.

The glitch? The manuscript evidently left out an author:

In Iyamu et al (2007), the list of authors was incorrectly published and should have read:

Efemwonkiekie W. Iyamu, Syed Jamal, Chiazotam Ekekezie and Gerald M. Woods

Or maybe not. The journal is now retracting the correction: Continue reading Lab squabble leads to retracted correction over authorship in British Journal of Haematology

New retraction sheds light on Medical College of Georgia vascular biology case

In late January, we wrote a post about a retraction in the journal Molecular Endocrinology involving work from the lab of Stephen M. Black, of the Vascular Biology Center at at the Medical College of Georgia.

At the time, we didn’t know much. The notice was pretty thin sauce, although it hinted at “significant concerns with the data,” and we were led to believe that the first author of the article, Neetu Sud, a post-doc in Black’s lab, might have been implicated in those concerns. Because Black’s lab was working with substantial amounts of NIH funding, the prospect of an investigation by the Office of Research Integrity seemed likely.

Now we have a little more to go on. The American Journal of Physiology: Lung Cellular and Molecular Physiology has retracted another article by Sud and Black. The paper, titled “Protein kinase Cδ regulates endothelial nitric oxide synthase expression via Akt activation and nitric oxide generation,” appeared in 2008 and included a third author, Stephen Wedgwood, of Northwestern University. It has been cited 10 times, according to Thomson Scientific’s Web of Knowledge.

Here’s the notice: Continue reading New retraction sheds light on Medical College of Georgia vascular biology case
