Novartis Diovan scandal claims two more papers

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):”

Duplication in physics journal questions key tenet of quantum mechanics

cmpHere’s a physics question: How is it possible to be in two places at the same time?

Answer: Submit the same manuscript twice and hope the editors forget to feed Schrödinger’s cat.

The journal Condensed Matter Physics is retracting a 2013 paper by a Ukrainian scientist who’d published essentially the same paper seven years earlier.The article was titled “On the origin of power-law distributions in systems with constrained phase space,” and was written by an E.V. Vakarin, of the Institute for Condensed Matter Physics, in Lviv UMR 7575 LECA ENSCP-UPMC-CNRS.

According to the abstract: Continue reading Duplication in physics journal questions key tenet of quantum mechanics

Regenerative medicine, regenerative publishing

devbioDevelopmental Biology has retracted a 2009 paper by an group of regenerative medicine specialists who, it seems, were regenerating more than just cells.

The article, titled “The human placenta is a hematopoietic organ during the embryonic and fetal periods of development,” was led by Susan Fisher, of the Institute for Regenerative Medicine at the University of California, San Francisco. It has been cited 32 times, according to Thomson Scientific’s Web of Knowledge.

Bogus Western blots lead to retraction of cancer paper

ejpharmA group of Italian researchers has retracted their 2013 paper on colorectal cancer because one of the authors, they, say, was tinkering with the data.

The article, “PBOX-15 induces apoptosis and improves the efficacy of oxaliplatin in human colorectal cancer cell lines,” appeared in the European Journal of Pharmacology in August. The first author was Giuseppina Gangemi, of the University of Salerno.

The paper purported to find that:

Neurosurgery journal retracts spine paper for lack of attribution

bjneurosurgA neurosurgeon in the UK has lost his 2013 paper on spinal surgery in the British Journal of Neurosurgery for doing what appears to have been an end-run around the folks that did the work.

The article, “The management of spinal dural fistulas: a 13-year retrospective analysis,” was written by Denosshan Sri, of Addenbrooke’s Hospital, in Cambridge.

Here’s the abstract:

“Unable to dispel the doubts,” authors lose protein structure paper

ebjA suggestion: If you’re going to use the words “overestimated accuracy” in the title of your paper, you’d better make sure you aren’t guilty of the same yourself.

A group of authors in China has lost their June 2013 paper in the European Biophysics Journal because they appear to have misinterpreted their data.  The paper, “Overestimated accuracy of circular dichroism in determining protein secondary structure,” came from chemists at Fudan University in Shanghai, and purported to find that:
