Out of the running: Dodgy blots prompt retraction of paper on marathoning and cell death

with 4 comments

bmc physiologyA group of exercise researchers at the University of Rome Tor Vergata has lost their May 2010 paper in BMC Physiology on the effects of marathon running on blood cells, because of figure irregularities.

The article, “The effect of marathon on mRNA expression of anti-apoptotic and pro-apoptotic proteins and sirtuins family in male recreational long-distance runners,” purported to find that marathoning arrested apoptosis, or programmed cell death. It has been cited 13 times, according to Thomson Scientific’s Web of Knowledge.

Retraction cites “unintended excessive reuse” in commentary — of paper it was praising

leave a comment »

rejuvreschcoverWe here at Retraction Watch HQ are always on the lookout for euphemisms for plagiarism (and other misconduct, of course). Among our favorites are “referencing failure” and the journal that allowed researchers to call plagiarism an “approach” to writing.

Here’s a new one that’s sure to do well with voters.

The journal Rejuvenation Research has retracted a commentary for, well, containing too much of the very text it was supposed to be commenting on.

The editorial was by Giorgio Aicardi, of the University of Bologna, in Italy, and the article Aicardi was writing about was titled “Synaptic distributions of GluA2 and PKMζ in the monkey dentate gyrus and their relationships with aging and memory.” That article had been published in the Journal of Neuroscience last year by a group from Mount Sinai in New York.

We’ll let the notice do the explaining: Read the rest of this entry »

Experimental & Molecular Medicine has retracted a 2012 paper on stroke by a group of South Korean researchers after learning that one of the figures in the article was unreliable.

The article was titled “Protective effects of transduced Tat-DJ-1 protein against oxidative stress and ischemic brain injury,” and it came from a team at Hallym University in Chunchon.

Eric Smart, the former University of Kentucky researcher found by the Office of Research Integrity to have faked images in ten papers, has two more retractions, both in the American Journal of Physiology — Cell Physiology.

Here’s one, for a paper cited four times, according to Thomson Scientific’s Web of Knowledge: Read the rest of this entry »

Lance Armstrong in the scientific literature: A “reconsideration”

with 11 comments

japhysIn January, as Lance Armstrong was performing the 21st century version of a confessional — appearing on Oprah — we wrote about a 2005 paper in the Journal of Applied Physiology about a “bicyclist who has now become the six-time consecutive Grand Champion of the Tour de France.”

That paper was, of course, about Armstrong, and in the months since our post, according to a just-published editorial, the editors of the journal asked author Edward Coyle of the University of Texas, Austin Read the rest of this entry »

Update: Data fabricator had masters’ degree revoked

with 9 comments

On Friday, we reported on the case of a retraction in the American Journal of Physiology — Cell Physiology by kinesiology researchers at Canada’s University of Waterloo for data fabrication by a graduate student, Sara Michelle Norris. We heard back from Waterloo yesterday, and have more details.

In our Friday post, we wondered whether Norris’s 2009 masters’ thesis,“Contribution of Sarcoplasmic Reticulum Calcium Pumping to Resting Mouse Muscle Metabolism,” might have been compromised. Waterloo tells us Norris is no longer at the university: Read the rest of this entry »

Data fabrication fells muscle physiology paper

with 16 comments

Kinesiology researchers at the University of Waterloo in Canada have been forced to retract a 2010 paper in the American Journal of Physiology — Cell Physiology in the wake of revelations that the first author, then a graduate student, fabricated her data.

The paper, “ATP consumption by sarcoplasmic reticulum Ca2+ pumps accounts for 50% of resting metabolic rate in mouse fast and slow twitch skeletal muscle,” was written by Sarah Michelle Norris and colleagues and published in March 2010.
