Retraction count for Dipak Das rises to 17

We have four more retractions by Dipak Das, the disgraced UConn researcher found by the university to have committed 145 counts of misconduct. All appear in the Journal of Molecular and Cellular Cardiology (we left the journal off when we initially posted, as commenters noted):

“Redox regulation of angiotensin II preconditioning of the myocardium requires MAP kinase signaling,” cited 28 times, according to Thomson Scientific’s Web of Knowledge:

Korean cardiology journal retracts one paper for plagiarism, and another for duplication

A Korean cardiology journal has retracted a 2011 review article because it “seriously” plagiarized a 2009 paper in another journal.

Here’s the notice, which is dated May 24, 2012 but just came to our attention, thanks to a post by Marilyn Mann: Continue reading Korean cardiology journal retracts one paper for plagiarism, and another for duplication

Seeing red (wine): Another retraction for Dipak Das, making count 13

Today’s Retraction Watch, to paraphrase Sesame Street, is brought to you by the number 13.

Earlier, we reported on several retractions from Diederik Stapel that bring his total to that number, and now we’ve learned about number 13 for Dipak Das. Das is of course the UConn researcher who was found to have committed 145 counts of misconduct in his studies of the red wine compound resveratrol and other subjects.

Here’s the notice, from The Journal of Nutritional Biochemistry, for “Resveratrol, a unique phytoalexin present in red wine, delivers either survival signal or death signal to the ischemic myocardium depending on dose:” Continue reading Seeing red (wine): Another retraction for Dipak Das, making count 13

Hypertension retracts paper over data glitch

The anticipation of having one’s blood pressure measured can cause it to spike.

So, evidently, can errors in data processing — on a national scale.

Hypertension, a journal published by the American Heart Association, has retracted a 2011 paper looking at the implications of blood pressure management guidelines after the authors discovered they had bungled the merging of their data files.

As the notice explains: Continue reading Hypertension retracts paper over data glitch

Mizzou investigating faculty as one heart beats as two in plagiarized — and now retracted — cardiac paper

The American Journal of the Medical Sciences has retracted a 2012 article on premature heartbeats by a group of authors in Missouri who took “significant” liberties with an earlier paper in Heart.

The offending paper, “Ventricular ectopic beats: an overview of management considerations, “was written by Amar Jadhav and colleagues at the University of Missouri School of Medicine, in Columbia, and published in the February issue of the AJMS.

According to the retraction notice: Continue reading Mizzou investigating faculty as one heart beats as two in plagiarized — and now retracted — cardiac paper

One year later, transcendental meditation study yanked minutes before publication still under review

A paper looking at the use of transcendental meditation to reduce the risk of heart disease, and that was put on hold just 12 minutes before its scheduled publication time, is still under review a year later.

On June 29 of last year, we brought you the news of the highly unusual — if not unprecedented — occurrence at the Archives of Internal Medicine. As we wrote then: Continue reading One year later, transcendental meditation study yanked minutes before publication still under review

Reverse tissue engineering: data reuse causes retractions of three papers from German organ researchers

The body count has reached three for a group of German tissue engineers who appear to have cloned their data in many of their publications.

Tissue Engineering Part A has retracted one of the papers from the investigators, titled “Clinically established hemostatic scaffold (tissue fleece) as biomatrix in tissue- and organ-engineering research,” which was published in 2003.

The notice states: Continue reading Reverse tissue engineering: data reuse causes retractions of three papers from German organ researchers

Circulation retracts four papers by author who misled on IRB approval

Circulation has retracted four articles by a pediatric cardiologist in Japan who failed to obtain ethics approval for the studies in question but evidently lied about it to the journal.

The researcher, Hideaki Senzaki, of Saitama Medical University, is a highly-published investigator who trained for a time with at Johns Hopkins.

According to the Circulation notice: Continue reading Circulation retracts four papers by author who misled on IRB approval

Retraction count for resveratrol researcher Dipak Das rises to 12

Das, via UConn

Dipak Das, the UConn researcher whom the university earlier ths year found to have fabricated or falsified data more than 100 times, has four more retractions to his name.

The notices appear in the June 1, 2012 issue of the American Journal of Physiology: Heart and Circulatory Physiology, and suggest that Das was not all that cooperative: Continue reading Retraction count for resveratrol researcher Dipak Das rises to 12

Not for the faint of heart: Cardiologists retract syncope paper after realizing data columns weren’t aligned right

Improperly aligned columns have cost researchers at the Mayo Clinic a paper in the Journal of the American College of Cardiology.

The paper originally concluded that fainting spells (syncope) give patients with high blood pressure in their lung arteries poor prognoses, an observation that turned out to be incorrect.

The problem? The group merged two electronic databases, but did not align columns properly, a problem found only after first author Rachel Le revisited the dataset looking to cull more data.

The retraction notice published on May 22 (the one on ScienceDirect is free to air, while the one on the JACC site is behind a paywall): Continue reading Not for the faint of heart: Cardiologists retract syncope paper after realizing data columns weren’t aligned right
