Image manipulation forces retraction of hepatitis C paper

ljii20.v032.i04.coverA group of researchers from Egypt has lost their 2013 article on hepatitis C in the Journal of Immunoassay and Immunochemistry for fudging their figures.

The article was titled “In vitro neutralization of HCV by goat antibodies against peptides encompassing regions downstream of HVR-1 of E2 glycoprotein.” According to the abstract: Continue reading Image manipulation forces retraction of hepatitis C paper

Former UT-Southwestern cancer researchers faked data in 10 papers: ORI

ut southwesternThe Office of Research Integrity (ORI) has ruled in a case we’ve been following for nearly two years — and which seems to have been launched after Retraction Watch readers took a careful look at figures from what appeared to be an unrelated case.

Takao Takahashi and Makato Suzuki, both former postdocs at a cancer research center at UT-Southwestern, both “knowingly, intentionally, and recklessly falsified data” in a total of 10 papers, according to the ORI. Takahashi, now at Gifu University in Japan, was responsible for fakery in four papers, while Suzuki, now at Kumamoto University Hospital, also in Japan, falsified data in six.

We reported on the retraction of the four Takahashi papers, and one of the Suzuki papers, in November 2012. At that time, Adi Gazdar, the head of the lab where the researchers worked, told us that

Publisher updates with more info on staph retraction

cidWe brought you this story last week, about a paper on drug resistant staph being retracted for a lab error. Now, we’ve got an update from Rachel Safer, senior editor for medical journals at Oxford University Press, where the paper was published.

Apparently, the researchers “inadvertently relied upon the use of a test system that was not approved for the microorganism studied in their paper,” leading to the retraction, and the corresponding author of the study wasn’t initially all that responsive:

Sinead Miggin, a biologist at the National University of Ireland Maynooth, has withdrawn two papers from the Journal of Biological Chemistry (JBC) and has corrected another paper, in the Proceedings of the National Academy of Sciences (PNAS).

Here’s the opaque JBC notice for “14-3-3ϵ and 14-3-3σ inhibit Toll-like receptor (TLR)-mediated proinflammatory cytokine induction,” a paper first published in November 2012: Continue reading Scientist in Ireland notches two mysterious retractions and a correction

Wrong in the tooth: Faked data, authorship issues force retraction of dental paper

cridCase Reports in Dentistry has pulled a 2014 article about an oral parasitic infection (caution: not pretty) after learning that the authors were not exactly honest about their work.

Here’s the abstract of the paper, “Rhinosporidiosis of the Parotid Duct”: Continue reading Wrong in the tooth: Faked data, authorship issues force retraction of dental paper

Fudged figures sink breast cancer paper

oncogeneA prestigious cancer journal has pulled an article over “concerns” regarding some of the figures, which PubPeer commenters had tagged as suspect.

A few weeks after the paper was published on June 9, comments on PubPeer began accumulating. Commenters called out both potentially manipulated and repeated images. The exact timeline is not clear, because Oncogene does not list a date on the retraction notice, but by August 29 the paper had been retracted.

Here’s the notice for “IL-6 secreted by cancer-associated fibroblasts induces tamoxifen resistance in luminal breast cancer,” by researchers at Shanghai Jiaotong University School of Medicine and Ruijin Hospital, both in Shanghai, China, and the University of Michigan: Continue reading Fudged figures sink breast cancer paper

87% of bugs resistant to antibiotics? Not so fast, as staph paper yanked after staff mistake

What could have been a truly scary study about drug resistant staph infections in hospitals has been retracted due to a lab error.

6.coverResearchers at a community hospital in Pittsburgh claimed that the commonly quoted 3% rate of staph that is resistant to ceftriaxone and sensitive to methicillin was drastically understated. However, an “honest error in the interpretation of a key lab test” called the findings into question.

Here’s the abstract: Continue reading 87% of bugs resistant to antibiotics? Not so fast, as staph paper yanked after staff mistake

Want bogus data, million-dollar fraud allegations and a scientist on the lam? We give you Alain Malafosse.

The British Journal of Psychiatry has retracted a June 2013 paper by Malafosse and his colleagues on the genetics of bipolar disorder in children because Malafosse allegedly fabricated key data in the study.

The article, “Childhood maltreatment and methylation of the glucocorticoid receptor gene NR3C1 in bipolar disorder,” purported to find that people with bipolar disorder who had experienced more, and more severe, abuse early in life were more likely to show epigenetic changes. According to the abstract:

First author blamed for retraction in prestigious medical journal

jemcoverThe authors of a Journal of Experimental Medicine have retracted it, blaming the first author for data and figure manipulation.

The paper, “The requirements for natural Th17 cell development are distinct from those of conventional Th17 cells,” was initially published in September 2011 and has been cited 25 times, according to Thomson Scientific’s Web of Knowledge. First author Jiyeon Kim was an MD-PhD candidate at the University of Pennsylvania until this year, according to a LinkedIn profile.
