Canada’s Memorial U says “substantial data misrepresentation” described by retraction notice was unintentional

Yesterday, we reported on a retraction in the Journal of Neuroscience for “substantial data misrepresentation.” When we posted, the authors’ institution, Memorial University in Newfoundland, Canada, had not been able to respond to our questions yet, because of the long Canada Day weekend. This morning, they sent us the following statement, which describes the errors that led to the retraction as unintentional: Continue reading Canada’s Memorial U says “substantial data misrepresentation” described by retraction notice was unintentional

Journal of Neuroscience retracts federally funded Canadian study with “substantial data misrepresentation”

The Journal of Neuroscience is retracting a paper by researchers at Memorial University in Newfoundland, Canada, after a university investigation found “substantial data misrepresentation” in the work, which was funded by two major federal agencies.

Here’s the notice: Continue reading Journal of Neuroscience retracts federally funded Canadian study with “substantial data misrepresentation”

Misconduct burns authors of wax paper, leads to sharply worded retraction notice

Philosophical Transactions of the Royal Society A is retracting a 2010 paper whose authors misappropriated data, forged an author name — and got a pretty strong backhand slap for the trouble.

The paper, “Green waxes, adhesives and lubricants,” which refers to eco-friendly materials, not Halloween-friendly slimes, was published by a group of researchers from China and Canada. Problem was, the one from Canada evidently didn’t know she was listed on the manuscript, and a big chunk of the work had been misappropriated from her university.

As the notice explains: Continue reading Misconduct burns authors of wax paper, leads to sharply worded retraction notice

Hair today, gone tomorrow: Hair loss company retracts public statements

Sorry, but we have some shocking news to report: That hair loss stock you bought may not be quite as promising as you were led to believe.

A release from Vancouver-based Replicel, which takes “dermal sheath cup cells…from a subject’s own healthy hair follicles,” replicates them “into the millions over a three month period,” and reintroduces them ” into areas of hair loss” with “the anticipated result the development of new hair follicles”: Continue reading Hair today, gone tomorrow: Hair loss company retracts public statements

Assay come, assay go: Corporate takeover leads to retraction of device analysis

A group of hematology researchers in Canada lost a publication to the merger of two medical device makers, after the acquiring company apparently decided not to pursue marketing the product in question.

An April 23 retraction notice in the International Journal of Laboratory Hematology about the article, “Enhanced flagging and improved clinical sensitivity on the new DxH 300TM Coulter® cellular analysis system,” originally published in February, tells the tale: Continue reading Assay come, assay go: Corporate takeover leads to retraction of device analysis

Gastro journal retracts duplicate review, but what really happened?

Current Opinion in Gastroenterology is a bimonthly journal “offering a unique and wide ranging perspective on the key developments in the field” that “features hand-picked review articles from our team of expert editors.”

Apparently, those hands picked what amounted to the same “unique” article twice. The journal is retracting a 2004 paper, “Enteral feeding,” by Khursheed Jeejeebhoy, an expert in nutrition at the University of Toronto (he’s now emeritus), because it duplicates a 2003 paper with the same title.

Here’s what the notice, which, lamentably, sits behind a paywall, has to say: Continue reading Gastro journal retracts duplicate review, but what really happened?

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

PLoS One and Nature Medicine have issued corrections for papers by Zhiguo Wang, the former Montreal Heart Institute researcher who resigned in September following an investigation into image manipulation in his lab. 

In September, PLoS One told us that they were investigating the paper. Here’s the text of the correction for “Transcriptional and Post-Transcriptional Mechanisms for Oncogenic Overexpression of Ether À Go-Go K+ Channel:” Continue reading Corrections in PLoS One, Nature Medicine for Zhiguo Wang, and details about Montreal Heart Institute investigation

Following investigation, U Ottawa lab retracting four papers in the Journal of Biological Chemistry

A University of Ottawa lab has been forced to retract four papers from the Journal of Biological Chemistry (JBC) after an investigation of image manipulation.

According to an email from a university official obtained by Retraction Watch, a university investigative committee had “found substance to the allegations,” although it claimed it could not disclose details “due to their confidentiality.” The university requested that the JBC withdraw a November 2005 paper, and left it to the journal to “determine whether the other articles should also be withdrawn or if they can be corrected. ” And they took the issue to the agency that funded the work: Continue reading Following investigation, U Ottawa lab retracting four papers in the Journal of Biological Chemistry

Zhiguo Wang retractions appear in the Journal of Cellular Physiology

Last month, we reported that the last three of six promised retractions by Zhiguo Wang, who was a researcher at the Montreal Heart Institute until the results of an Institute investigation forced him to resign in early September — would be in the Journal of Cellular Physiology. They’ve now appeared.

Here are the three notices, which are far more informative than the Journal of Biological Chemistry was — and which make it clear Wang acted alone: Continue reading Zhiguo Wang retractions appear in the Journal of Cellular Physiology
