Elsevier weighs in on Brazilian fraud case

Yesterday, we reported on 11 retractions in various Elsevier chemistry journals of papers from a group of Brazilian scientists who are alleged to have fabricated nuclear magnetic resonance images used in their articles.

We’d spoken with the senior author on those papers, Claudio Airoldi, who defended himself and his colleagues and denied that the NMR images had been manipulated.

Today, we heard from Tom Reller, vice president for global corporate relations at Elsevier, who offered a different version of events.

Here’s what Reller had to say, straight from his email: Continue reading Elsevier weighs in on Brazilian fraud case

Hazardous materials: Elsevier retracts 11 chemistry papers from Brazilian group, citing fraud

The publisher Elsevier has announced that it is retracting 11 papers from a team of Brazilian researchers over concerns that the scientists committed fraud in the studies.

The notice is pegged to an October 2009 article in the Journal of Colloid and Interface Science titled “Immobilization of 5-amino-1,3,4-thiadiazole-thiol onto kanemite for thorium(IV) removal: Thermodynamics and equilibrium study” by Denis L. Guerra, Marcos A. Carvalho, Victor L. Leidens, Alane A. Pinto, Rúbia R. Viana, and Claudio Airoldi.

Freedom from Information Act? Another JBC retraction untarnished by any facts

There’s helpful but uninformative:

Ivan: What’s the weather like today?

Adam: Sunny.

And then there’s uninformative as served up by the Journal of Biological Chemistry.

We’ve already recounted one teeth-grinding experience with the JBC, a publication of the American Society for Biochemistry and Molecular Biology. The case involved two papers in JBC by Axel Ullrich, an esteemed cancer researcher at the Max Planck Institute in Germany. According to Ullrich, one of his then-postdocs, Naohito Aoki, had manipulated figures that appeared in the papers, necessitating their retraction.

Round two involves another JBC retraction of a 2000 paper by Aoki and co-author Tsukasa Matsuda, titled ‘A cytosolic protein-tyrosine phosphatase PTP1B specifically dephosphorylates and deactivates prolactin-activated STAT5a and STAT5b.’ The paper has been cited more than 100 times, according to Thomson Scientific’s Web of Knowledge.

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”

In a retraction’s wake: Postdoc Shane Mayack, dismissed from Amy Wagers’ stem cell lab, speaks out

 

Last October, Retraction Watch readers will recall, up-and-coming stem cell researcher Amy Wagers retracted a study in Nature describing how her team rejuvenated blood-forming stem cells in older mice. Shane Mayack, a postdoc in Wagers’ lab who had been dismissed after an inquiry into what happened, did not sign that retraction. Since then, Mayack has not spoken to the press, except for a brief comment to Nature through her attorney.

Here, we present, unedited, Mayack’s side of the story. While accepting responsibility, she also has a number of suggestions for how universities and journals can handle these situations better. Shane can be reached at smayck[at]yahoo.com.

Since it was well covered by this blog, the readers of Retraction Watch are no doubt aware that in October 2010, a paper that I co-authored was retracted from Nature and a notice of concern was posted regarding a second paper published in Blood.

So, what went wrong? Continue reading In a retraction’s wake: Postdoc Shane Mayack, dismissed from Amy Wagers’ stem cell lab, speaks out

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

Naoki Mori, with 16 retractions, to be rehired?

Naoki Mori

Naoki Mori, of 16-retraction fame, believes he’s getting his job back at the University of the Ryukyus, which released him in August after learning that the cancer researcher had misused images in many of his publications.

According to a report in Science Insider, Mori’s penalty has been reduced to a 10-month suspension, and he will resume his professorship in June. Mori apparently also told Science that some journals “are considering accepting corrected papers,” although he didn’t name them. Continue reading Naoki Mori, with 16 retractions, to be rehired?

Joachim Boldt retraction tally drops by one, editors say (but record’s still safe)

As the news of Joachim Boldt’s staggering number of retractions leaps from Retraction Watch into the mainstream press, the consortium of journal editors retracting his studies has backtracked ever so slightly, announcing today that one of the 89 studies for which the German anesthesiologist lacked ethics approval in fact had such sanction.

According to the now-16 (Updated 3/7/11, as it is up from 11 several days ago) editors, LÄK-RLP,  the German body investigating the ethics component of the Boldt case: Continue reading Joachim Boldt retraction tally drops by one, editors say (but record’s still safe)

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
