with 9 comments

agecoverAge has retracted a 2012 article by a group of scientists from the National Institutes of Health and Brigham and Women’s Hospital in Boston after an NIH inquiry turned up evidence of data manipulation in the work.

The article, “Aging decreases rate of docosahexaenoic acid synthesis-secretion from circulating unesterified α-linolenic acid by rat liver,” came from the lab of Stanley Rapoport, chief of the brain physiology and metabolism section of the National Institute on Aging.

Fraud fells Alzheimer’s “made to order” neurons paper in Cell

with 7 comments

cell414In 2011, a group of researchers at Columbia University reported in Cell that they had been able to convert skin cells from patients with Alzheimer’s disease into functioning neurons — a finding that raised the exciting prospect of “made to order” brain cells for patients with the degenerative disease. As one researcher not involved with the study, led by Asa Abeliovich, put it:

“[This is] simply a remarkable and complete piece of work which will now set a standard for stem cell work in neurological disease. The standard of the characterization of the neuronal cultures is very high,” John Hardy at University College London, U.K., wrote to [Alzforum]. He was not involved in the work but is taking a similar approach in his own lab.

According to the abstract of “Directed Conversion of Alzheimer’s Disease Patient Skin Fibroblasts into Functional Neurons:”

Pain study retracted for bogus data is second withdrawal for University of Calgary group

with 8 comments

molpainBack in January 2013, we wrote about the retraction of a paper in Diabetes that the authors had “submitted without knowledge of inherent errors or abnormalities that they recognized in retrospect after submission.”

Now, Molecular Pain has retracted a paper by the same authors, this time for data manipulation. The article, “Comparison of central versus peripheral delivery of pregabalin in neuropathic pain states,” was written by Cory Toth, a clinical neuroscientist at the University of Calgary, in Canada, and colleagues. It has been cited eight times, according to Thomson Scientific’s Web of Knowledge.

Toth said of the Diabetes article at the time:

MS paper second to fall following University of Queensland investigation

with 5 comments

aphasiologyTwo former University of Queensland researchers have lost another paper following an investigation into their work.

In September, the university announced that a paper in the European Journal of Neurology by Bruce Murdoch and Caroline Barwood would be retracted because

no primary data can be located, and no evidence has been found that the study described in the article was conducted.

The university continued its investigation, and announced today that: Read the rest of this entry »

Novartis Diovan scandal claims two more papers

with 5 comments

diabetes careA complicated story involving Novartis’s valsartan (Diovan) has led to the retraction of two more papers, one cascading from the other.

Last September, The Lancet retracted the Jikei Heart Study after a slew of retractions of related work prompted an investigation of valsartan research. That investigation found evidence of data manipulation and the failure of one researcher to note his Novartis affiliation. The company has apologized.

Here’s one retraction, from Diabetes Care, for “The Shiga Microalbuminuria Reduction Trial (SMART) Group. Reduction of Microalbuminuria in Patients With Type 2 Diabetes: The Shiga Microalbuminuria Reduction Trial (SMART):”
