Too much skin in the game, as duplications force retraction of psoriasis paper

actadermA group of dermatology researchers from Egypt who passed around a psoriasis paper like a bottle of sunscreen at the beach have been burned (sorry) by a journal that caught them in the act.

Acta Dermatovenerologica Alpina, Pannonica et Adriatica is retracting the 2009 article “Association of cytokine gene polymorphisms with psoriasis in cases from the Nile Delta of Egypt” after discovering that they were far from the first publication to print the paper.

Here’s the retraction notice (it’s a pdf): Continue reading Too much skin in the game, as duplications force retraction of psoriasis paper

When two words colloid: “copied and manipulated” figures prompt retraction of nanoparticle paper

colloids and surfaces bThe journal Colloids and Surfaces B: Biointerfaces has retracted a 2011 paper by a group of researchers in India who misappropriated — and then manhandled — a pair of images from a previously published article by other scientists.

The paper, “Synthesis and characterization of chitosan and grape polyphenols stabilized palladium nanoparticles and their antibacterial activity,” was written by authors from various institutions in Tamil Nadu, and appeared online in December 2011 and in print the following April. It has been cited three times, according to Thomson Scientific’s Web of Knowledge.

Here’s the abstract: Continue reading When two words colloid: “copied and manipulated” figures prompt retraction of nanoparticle paper

Chemistry papers retracted for “lack of objectivity:” The authors did their own peer review

synthreactSynthesis and Reactivity in Inorganic, Metal-Organic, and Nano-Metal Chemistry is retracting three articles for duplication — redundancy the authors, chemical engineers at Islamic Azad University, in Shahreza, Iran, appear to have gotten around by reviewing their own manuscripts. But, if they did say so themselves, those papers were really something!

Here’s the retraction notice for two of the papers, both of which appeared in 2012 and which were cited seven times and once, respectively, according to Thomson Scientific’s Web of Knowledge:

Ask Retraction Watch: Should these papers be retracted?

protein scienceLast week, we reported on a new paper by Scripps Research Institute researchers in which they described how two of their previous papers had been based on mistaken interpretations. The authors wrote in their new paper that they were retracting the earlier works, but the journal had told them the papers would be corrected instead.

We had asked Protein Science editor Brian Matthews for clarification, and he emailed us late last week:

Aussie university asks for retraction, investigates former neurology researcher for fraud

uqThe University of Queensland has decided to get out in front of a serious research misconduct scandal by issuing a press release about the item even before, well, we could get a hold of the story.

The affair involves Bruce Murdoch (all of his links at UQ are defunct), an expert in movement disorders such as Parkinson’s disease. Murdoch isn’t named in the release, but he is the corresponding author of the retracted paper, which is called out in the statement.

According to UQ, Murdoch seems to have published a paper in the European Journal of Neurology on research he never conducted — and on the basis of which he received a $20,000 grant. The paper has been cited six times, according to Thomson Scientific’s Web of Knowledge.

UQ has called for a retraction of the paper, although that does not appear to have happened yet.

Here’s the release, from Peter Høj, president and vice chancellor of the institution, in its entirety: Continue reading Aussie university asks for retraction, investigates former neurology researcher for fraud

Regrettable, but not scientifically dishonest: Klarlund Pedersen responds to Danish committee

A Danish researcher has responded to a draft report of the Danish Committees on Scientific Dishonesty (DCSD) that found she had acted in a “scientifically dishonest” and “grossly negligent” manner.

Bente Klarlund Pedersen, a University of Copenhagen researcher, has published with Milena Penkowa, four of whose papers have been retracted following investigations. In the press, she argued that while she had made mistakes, she had not committed misconduct.

The 57-page letter from Klarlund Pedersen’s attorney to the DCSD responds in detail to the critique of her work, including twelve papers. This passage from the summary gathers the arguments together: Continue reading Regrettable, but not scientifically dishonest: Klarlund Pedersen responds to Danish committee
