Another retraction of Spirocor research

Remember Spirocor, the Israeli company that closed down a clinical trial involving its “respiratory stress” test for coronary artery disease because the data underpinning the validity of the method proved unreliable? The problem led to the retraction of two articles, about which we’ve previously reported. But we also found a study by some of the same researchers, who include scientists in Israel and the United States, that had been presented at the 2010 meeting of the American Heart Association and published in the journal Circulation.

That abstract, No. 14426 “Accuracy and Usefulness of Finger Pulse Wave Analysis during Brief Deep Breathing Exercise (Respiratory Stress Response) as a Marker of Significant Coronary Artery Disease,” has now been retracted — making, to our knowledge, the entire body of published research on the Spirocor product an editorial memory.

Here’s the notice, which appears within the text of the abstract: Continue reading Another retraction of Spirocor research

Sigh: “The purpose of keeping these retraction notices slim is not to produce too much detail”

Regular readers of this blog by now know that one of our goals is to make retractions as open and informative as possible. Which is why when they’re not, we get irritated that not everyone seems to agree.

Consider the editors of Computational and Theoretical Chemistry, which this month has retracted two papers from a group of researchers in Iran. The articles were titled “Determination of the electrode potentials for substituted 1,2-dihydroxybenzenes in aqueous solution: Theory and experiment” first published online in July 2006 and cited 25 times, according to the Thomson Scientific Web of Knowledge, and “Calculation of electrode potentials of 5-(1,3-dioxo-2-phenyl-indan-2-yl)-2,3-dihydroxy-benzoic acid, molecular structure and vibrational spectra: A combined experimental and computational study,” which appeared in December 2006. (Both articles were published in the journal’s previous incarnation as the Journal of  Molecular Structure: THEOCHEM.)

The reason given in each case  is the same — and tantalizingly cryptic: Continue reading Sigh: “The purpose of keeping these retraction notices slim is not to produce too much detail”

Aftermath: Gut-wrenching misstep leads to retraction, frayed feelings and a paperless postdoc

Graham Ellis-Davies says January 25th was one of the worst days of his life. That was when the journal ChemBioChem retracted an article, published barely two weeks earlier, for a mistake Ellis-Davies blames squarely on himself.

The fallout has been nearly two months of painful self-recrimination, a tattered friendship and, perhaps most significant, he adds, the wasted effort of a postdoc who poured months of research into a now worthless publication. Continue reading Aftermath: Gut-wrenching misstep leads to retraction, frayed feelings and a paperless postdoc

Tenth Bulfone-Paus retraction notice appears, in Journal of Biological Chemistry

The tenth of 12 promised retractions by Silvia Bulfone-Paus and colleagues has appeared, in the Journal of Biological Chemistry (JBC).

The paper, “Reverse signaling through membrane-bound Interleukin-15,” was published in 2004 and has been cited 31 times, according to Thomson Scientific’s Web of Knowledge. The retraction notice, just like the other one for the team’s work that appeared in the JBC, was completely uninformative: Continue reading Tenth Bulfone-Paus retraction notice appears, in Journal of Biological Chemistry

Plagiarism and other ‘negligence’ fell lung-estrogen paper

There’s parsing a-plenty in the American Journal of Physiology Lung Cellular and Molecular Physiology this month. The journal has retracted a 2010 paper by researchers at Chiba University in Japan, who lifted much of their manuscript from an article by other scientists in a different publication.

The authors of the paper, “The estrogen paradox in pulmonary arterial hypertension,” confess that they misappropriated text. But how they do so is a case study in subtlety: Continue reading Plagiarism and other ‘negligence’ fell lung-estrogen paper

Ladies and gentlemen, we have an apparent retraction record holder: Joachim Boldt, at 89

It’s official.* Joachim Boldt now holds the record for the most retractions by a single author.

As we reported the other day, a group of anesthesia journals was on the verge of revealing a list of 89 articles by Joachim Boldt that would require retraction because the German researcher had failed to receive proper approval from ethics officials for his studies. Today, the coalition issued a letter making the retractions official.

The 89 papers join an earlier retraction in October.

Of note: Continue reading Ladies and gentlemen, we have an apparent retraction record holder: Joachim Boldt, at 89

Two more retractions for Mori make 16 — but not a record

Biochemical Journal has retracted two articles by Naoki Mori, bringing the total number of pulled papers by the Japanese cancer researcher to sixteen.

As with the previous Mori retractions, the latest ones — of papers published in 2007 and 2010 — involve unreliable images. Mori, you’ll recall, had recycled control blots from study to study over the years, and was dismissed from his academic post in August.

The 2007 paper, “Activation of hypoxia-inducible factor 1 in human T-cell leukaemia virus type 1-infected cell lines and primary adult T-cell leukaemia cells,” also included a frequent co-author Mariko Tomita, who has been implicated in the deception. It has been cited 15 times, according to Thomson Scientific’s Web of Knowledge. The 2010 article, “Inhibition of Akt/GSK3β signalling pathway by Legionella pneumophila is involved in induction of T-cell apoptosis,” has not yet been cited.

In each case, the retraction notice is the same: Continue reading Two more retractions for Mori make 16 — but not a record

University of Sao Paulo fires professor after a retraction for plagiarism

February has turned out to be a bad month for people found guilty of plagiarism. On Friday, we covered the case of the German foreign defense minister who lost his PhD after his university became aware he had copied passages from newspaper stories into his thesis.

And now we’ve learned that the University of Sao Paolo Paulo (USP) dismissed a full professor earlier this month after an investigation into a study he retracted last year because parts of it had been plagiarized. It has also stripped one of the professor’s former students of her PhD. Continue reading University of Sao Paulo fires professor after a retraction for plagiarism

Ninth Bulfone-Paus retraction notice appears, in Molecular and Cellular Biology

Another retraction notice for a paper published by Silvia Bulfone-Paus and colleagues has appeared, this one for a 2005 paper in Molecular and Cellular Biology.

The retraction notice is brief but to the point: Continue reading Ninth Bulfone-Paus retraction notice appears, in Molecular and Cellular Biology

Korean ENT journal retracts 17 papers, citing ‘overlap’

The Korean Journal of Otolaryngology-Head and Neck Surgery has retracted 17 papers, with the common theme of ‘overlap’ — almost always a euphemism for plagiarism, whether self or otherwise.

Published between 1993 and 2006, the articles came from a group of authors at the department of otolaryngology at Ajou University School of Medicine in Suwon, South Korea. Their topics range from “The Effects of Intratympanic Steroid Injection for the Patients with Refractory Sudden Sensorineural Hearing Loss” to “Study for Reversibility of Experimental Cholesteatoma Using Mongolian Gerbil.”

The retraction notices all read basically the same way. Here’s the one for the gerbil paper: Continue reading Korean ENT journal retracts 17 papers, citing ‘overlap’
