An Australian university has put a hold on trials of an experimental drug for skin cancer whose main developer has been dogged by charges of research misconduct for several years.

The Australian Broadcasting Corporation is reporting that the University of New South Wales has suspended trials of the drug, DZ13, while it investigates the work of Levon Khachigian, who is leading the studies.

According to the news organization, Khachigian and his group were cleared by the school in two prior inquiries. However, additional accusations of misconduct — specifically involving image manipulation and misuse — prompted a third investigation.

We’ve found four retractions of Khachigian’s studies, from the Journal of Biological Chemistry and Biochemical and Biophysical Research Communications, between 2009 and 2010 (before the launch of Retraction Watch).

They are: Continue reading Aussie university halts trials of skin cancer drug whose developer has four retractions

The Office of Research Integrity (ORI) has sanctioned an assistant professor of dermatology at Case Western Reserve University in Cleveland for plagiarizing from a grant application she was reviewing — which feels like a scientific version of insider trading — and a number of published papers.

According to the ORI’s findings, Pratima Karnik Continue reading Case Western dermatology department hit with second ORI sanction within 6 months

Five months after the Office of Research Integrity announced they had found evidence of misconduct by Adam Savine, a former Washington University graduate student in neuroscience, another journal has published a retraction of his work.

Here’s the retraction notice in the Journal of Experimental Psychology: General for “A characterization of individual differences in prospective memory monitoring using the Complex Ongoing Serial Task”:

Birds of a feather: Authors who play games with fowl data earn multiple retractions

jmicrobiotechA group of animal health researchers from the Chinese Academy of Agricultural Sciences have lost their 2009 paper in the Journal of Microbiology and Biotechnology because they’d published the data in at least four other articles.

The paper, “Two Novel Duck Antibacterial Peptides, Avian β-Defensins 9 and 10, with Antimicrobial Activity,” reported that: Continue reading Birds of a feather: Authors who play games with fowl data earn multiple retractions

A sad postscript: Paper by deceased researcher retracted

cancer researchIt was the last study ever published from prominent scientist Gerd Maul’s lab. And now it’s been retracted.

Maul was a highly cited cell biologist, with 30 papers cited at least 100 times, according to Thomson Scientific’s Web of Knowledge. He was also a well-known sculptor. When he died in 2010, he had a paper under submission at Cancer Research, which was published late that year.

This year, however, his co-authors found problems with the study. And as the notice — one of the most detailed we’ve ever seen — explains: Continue reading A sad postscript: Paper by deceased researcher retracted

“Sufficient concern” about data prompts retraction of T-cell paper

journal of immunology 8 15The Journal of Immunology has retracted a 2011 paper on T cell activity after the authors decided they couldn’t stand by the reliability of the work.

The article was titled “Human Regulatory T Cells Require IL-35 To Mediate Suppression and Infectious Tolerance.” (On Pubmed the title has the rather ironic precursor “Cutting edge” in front). Here’s the abstract: Continue reading “Sufficient concern” about data prompts retraction of T-cell paper

Anticancer-fungus paper retracted because some of the results “may be inaccurate”

biomacroMaybe it was a case of hitting the “send” button a bit too soon, or maybe it was a spasm of seller’s remorse, but a group of Chinese researchers has retracted a paper they’d published preliminarily a few months earlier.

The paper, “Antitumor and immunomodulatory activity of a polysaccharide from fungus Coprinus comatus (Mull.:Fr.) Gray,” by a group from various institutions in Shaanxi, appeared in April on the website of International Journal of Biological Macromolecules (as what appears to have been an uncorrected proof). But that didn’t stick.

According to a retraction notice dated August 2nd: Continue reading Anticancer-fungus paper retracted because some of the results “may be inaccurate”

Privacy breach prompts retraction of three papers from the trauma literature

ejpsychtraumA group of international psychology researchers is retracting three papers in the wake of revelations that they failed to adequately safeguard the identities of the patients who participated in the studies.

So far, only one article has been formally retracted. That article, “Combining biofeedback and Narrative Exposure Therapy for persistent pain and PTSD in refugees: a pilot study,” appeared last year in the European Journal of Psychotramatology. Its authors were Naser Morina, Thomas Maier, Richard Bryant, Christine Knaevelsrud, Lutz Wittmann, Michael Rufer, Ulrich Schnyder and Julia Müller.

According to the notice: Continue reading Privacy breach prompts retraction of three papers from the trauma literature

Retraction notice for cancer paper gives wide berth to the “p” word

jneuroncolThe Journal of Neuro-Oncology has retracted a 2009 article on brain tumors for what’s clearly plagiarism — but which is called everything but.

The article was titled “Glioma grading: sensitivity, specificity, positive and negative predictive values of diffusion and perfusion imaging,” and it came from a group at the Sree Chitra Tirunal Institute for Medical Sciences and Technology, in Trivandrum, India.

Here’s the — rather laughable — retraction notice, which dances around the matter about as deftly as a freshman with the prom queen:
