The authors of a 2008 paper alleging to have described how a particular protein binds to the parathyroid hormone have retracted it. The paper, “Structure of the Parathyroid Hormone Receptor C Terminus Bound to the G-Protein Dimer Gβ12,” has been cited 12 times, according to Thomson Scientific’s Web of Knowledge. According to the notice: Continue reading Ties that don’t bind: Group retracts parathyroid hormone crystallography paper
We have an update to our coverage of the retractions involving papers from a group of researchers in Iran that were published in Computational and Theoretical Chemistry (formerly called the Journal of Molecular Structure: THEOCHEM)
Although we have not received a response from the first author of those studies, Siavash Riahi, one author, Mohammad Reza Ganjali, of the Center of Excellence in Electrochemistry at the University of Tehran, sent us a lengthy comment recently. We post his remarks in their entirety here, unedited: Continue reading Chemist: “corresponding author should answer” questions regarding retracted papers
Back in March, we reported that the journal Computational and Theoretical Chemistry (CTC) had retracted a pair of 2006 papers by a group of Iranian researchers. As the notices stated, the scientists had recalled their articles after detecting “serious errors” with the work post-publication.
At the time, the authors still had three other articles in good standing with CTC. No longer.
CTC has retracted the remaining three papers by the group, for the same “serious errors.” The articles appeared between 2007 and 2009, and were titled: Continue reading Three more chemistry papers fall to “serious errors” of unknown nature
A prominent Stanford University chemistry lab has been forced to retract a paper in the Journal of the American Chemical Society (JACS). According to the retraction notice:
Due to inconsistencies between some of the assigned structures and the experimental data that appear in the paper, the authors retract this publication. We regret very much this unfortunate occurrence.
The Retraction Watch tipster who alerted us to this retraction explained what the original paper reported: Continue reading Stanford group retracts JACS paper, but revisits and validates findings
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
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.
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”
Earlier this month, we reported that a group led by Jicun Ren, of Shanghai Jiaotong University, had retracted a paper in the Journal of the American Chemical Society (JACS) on a way to measure the concentration of gold nanoparticles. Turns out they are also retracting a very similar paper about silver nanoparticles published in the January 18, 2010 issue of Chemistry: A European Journal.
Ren tells Retraction Watch that the silver paper, “Ultrahighly sensitive homogenous detection of DNA and microRNA by using single-silver-nanoparticle counting,” is being retracted for the same reason as the gold one. From our earlier post (just substitute “silver” for “gold”): Continue reading No medals: Group that retracted JACS gold nanoparticle paper retracts silver one, too
The Office of Research Integrity has thrown a heavy book at Bengu Sezen, a former chemist at Columbia University, alleging that school and agency investigators turned up 21 instances of research misconduct by the disgraced scientist.
One of the world’s leading cancer researchers, Axel Ullrich of Germany, has retracted two papers published in the Journal of Biological Chemistry.
Ullrich, director of microbiology at the Max Planck Institute of Biochemistry, has been a central figure in many groundbreaking discoveries, from the development of genetically engineered insulin to the identification of the breast cancer gene HER2. The founder of several biotech firms, he also runs an international consortium, the Singapore Oncogenome Project, looking for other so-called oncogenes linked to protein-tyrosine kinase, or PTK, an enzyme that regulates cell growth and which, when run amok, is implicated in a variety of tumor types.
The retractions involve two articles, published eight years apart, on protein-tyrosine. The first, from 1996, was titled Continue reading Leading cancer scientist retracts two papers, one 14 years old, but journal won’t say why
