Dubious stem cell researcher Moriguchi notches temporary withdrawal, notice of redundant publication

bmj case reportsHisashi Moriguchi, who retracted two papers last year because he and his colleagues could not “guarantee the accuracy of the results and conclusions,” has now had another paper withdrawn — at least temporarily.

A notice on the paper, “Autologous human cardiac stem cells transplantation for the treatment of ischaemic cardiomyopathy: first study of human-induced pluripotent stem (iPS) cell-derived cardiomyocytes transplantation,” which appeared in BMJ Case Reports, now reads: Continue reading Dubious stem cell researcher Moriguchi notches temporary withdrawal, notice of redundant publication

Authors withdraw already-corrected JBC paper questioned on PubPeer

jbc 8-9-13An assistant professor of neuroscience at Tufts has withdrawn a paper published last year after one round of corrections wasn’t enough to fix all of the study’s problems.

The study, “Sirtuin 2 (SIRT2) enhances 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced nigrostriatal damage via deacetylating forkhead box O3a (Foxo3a) and activating Bim protein,” by Gizem Donmez and colleagues, had already been subject to an extensive correction in May: Continue reading Authors withdraw already-corrected JBC paper questioned on PubPeer

Aussie university halts trials of skin cancer drug whose developer has four retractions

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

Penkowa notches fourth retraction, in Experimental Neurology

exp neuroMilena Penkowa, the Danish neuroscientist who resigned from the University of Copenhagen in December 2010 amid suspicions of misconduct, has had another paper retracted.

The new retraction appears in Experimental Neurology. Here’s the notice for “M-CSF deficiency leads to reduced metallothioneins I and II expression and increased tissue damage in the brain stem after 6-aminonicotinamide treatment”: Continue reading Penkowa notches fourth retraction, in Experimental Neurology

Journal retracts a 24-year-old sociology paper for plagiarism–of a 1975 article

soafrevsocThe South African Review of Sociology has retracted a 1989 paper by an author who must have figured the source — a 1975 article — was sufficiently well removed from institutional memory to catch anyone’s eye.

Evidently that was a safe bet for a generation. But we’re guessing the Internet permitted the detective work that eventually brought the theft to light.

The article was titled (oddly), “Doing the Knowledge in Literature and Sociology,” and its author was P.N.G. Beard, who since 2008 has been group chief education officer at Educor, “the largest provider of private education in Southern Africa.” Beard seems to have written an academic text or two, with titles including  “Problems of Pedagogics: Pedagogics and the Study of Education in South Africa,” and  “The Child Is Father of the Man: Inaugural Lecture.”

Here’s the retraction notice: Continue reading Journal retracts a 24-year-old sociology paper for plagiarism–of a 1975 article

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”:

Carbon copies? Authors retract paper from leading chemistry journal

jacsat_v135i031.inddThe authors of a 2008 Journal of the American Chemical Society (JACS) paper have retracted it after a structure was “mistakenly assigned.”

The article, “Highly Enantioselective Radical Addition to N-Benzoyl Hydrazones Using Chiral Ammonium Salts,” was written by Doo Ok Jang and Sang Yoon Kim, chemists at Yonsei University, in Wonju. According to the abstract (which includes this molecular schema):

Insert data here … Did researcher instruct co-author to make up results for chemistry paper?

orgnd7_v032i014.inddThe chemistry blogs have been buzzing this week with the story of a paper in the journal Organometallics that may — or may not — contain fabricated data.

But what makes the story a bit juicier — and yes, it’s sad that fabricated data is a bit ho-hum for us — is that one of the authors of the article appears to have been caught in the act of instructing the first author to make up results.

The article, “Synthesis, Structure, and Catalytic Studies of Palladium and Platinum Bis-Sulfoxide Complexes,” appeared last month and came from a group at the Institute for Organic Chemistry at the University of Zurich. The authors were Emma E. Drinkel, Linglin Wu, Anthony Linden and Reto Dorta.

As ChemBark reported earlier this week:

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
