Cancer paper pulled due to “identical text” from one published 6 days prior; author objects

ClinCancRes_ak16Clinical Cancer Research is retracting a paper on the immunosuppressive effects of glioma due to “evidence of duplicate and/or redundant publication.”

According to the retraction notice, the 2010 paper bore exceeding similarities to another one published by the same group of researchers six days prior. That second paper appeared in Molecular Cancer Therapeutics, which – like Clinical Cancer Research — is published by the American Association for Cancer Research. Apparently, a reader tipped off the AACR about the similarity.

The corresponding author on both papers, however, has objected to the decision: Continue reading Cancer paper pulled due to “identical text” from one published 6 days prior; author objects

“Evidence of data duplication” infects lung inflammation paper from Harvard and Yale

IAIA team of Harvard and Yale biologists have retracted an Infection and Immunity paper due to data duplication.

After the duplication came to light, the erroneous figures were corrected using original data, but the results affected “some of the manuscript’s conclusions.” An ethics panel subsequently recommended retraction, according to the journal, and the authors agreed.

The paper, “NOD2 Signaling Contributes to Host Defense in the Lungs against Escherichia coli Infection,” analyzed the role of the gene NOD2 in the lung inflammatory response against the bacteria Escherichia coli. It has been cited by 15 other papers, according to Thomson Scientific’s Web of Knowledge.

Figure 2B of the paper was previously corrected in 2012, but the retraction is for data duplication in figures 5F and 6A. Here’s the full retraction note: Continue reading “Evidence of data duplication” infects lung inflammation paper from Harvard and Yale

“I hold my hands up”: PubPeer criticisms spark a biochemist’s offer to retract

MPIn a back-and-forth on PubPeer, a researcher appears to have offered to retract a paper after commenters challenged the use of identical control bands on a gel.

A person writing as Virginia Commonwealth University biochemist Paul Dent admitted the control bands of his 2007 Molecular Pharmacology paper, “Human Chorionic Gonadotropin Modulates Prostate Cancer Cell Survival after Irradiation or HMG CoA Reductase Inhibitor Treatment,” were duplicated “for comparison purposes,” but stated he was “in no way attempting to ‘intentionally manipulate the data.’”

In response, Dent appeared to offer to pull the paper, about using a hormone to help kill prostate cancer cells:

Exosome pioneer’s paper retracted after investigation finds “multiple” faked figures

JImmunolThe Journal of Immunology is retracting a 2006 article about the role of exosomes in pregnancy at the behest of the University of Louisville in Kentucky, following a misconduct investigation that “determined multiple figures” in the paper were falsified.

First author Douglas Taylor is a pioneer in exosome biology, having discovered the release of exosomes from tumor cells in the 1970s.

The retracted paper identified “significant quantitative and qualitative differences in released exosomes” in the placentas of fetuses delivered prematurely compared to those delivered without complications at term, particularly relating to immune regulation.  It has been cited 150 times, according to Thomson Scientific’s Web of Knowledge.

Here’s the retraction note (which is paywalled – tsk, tsk): Continue reading Exosome pioneer’s paper retracted after investigation finds “multiple” faked figures

Another “first author has accepted responsibility” retraction from immunity journal

IAIScientists have pulled their 2013 Infection and Immunity paper after a reader noticed duplicated data in three figures, and the first author was “unable to provide the original data used to construct the figures,” according to the journal’s editor-in-chief.

According to the retraction note, “the first author has accepted responsibility for these anomalies” — similar to another recent retraction from the same journal, also due to image duplication reported by a reader (apparently the journal has one or more careful readers).

The paper, “Pseudomonas aeruginosa Outer Membrane Vesicles Modulate Host Immune Responses by Targeting the Toll-Like Receptor 4 Signaling Pathway,” concerns the role of outer membrane vesicles excreted by the bacteria to incite an inflammatory response in mice. It was written by authors at the University of North Dakota, Sichuan University in China, and the University of Chicago, and has been cited six times, according to Thomson Scientific’s Web of Knowledge.

Here’s the complete retraction note:

The “results should not be published:” Company confidentiality agreement squashes two insecticide papers

AMTWest Virginia University biologists have retracted two papers on insecticides for fruit pests due to a confidentiality agreement with a chemical manufacturer stating that the “results should not be published.”

The retracted 2014 articles in Arthropod Management Tests, “Control of Internal Lepidoptera and other insect pests in apple, 2013” and “Control of Oriental Fruit Moth and other insect pests in peach, 2013,” were written by WVU entomologist Daniel Frank and plant pathologist Alan Biggs.

We’ve been unable to find abstracts for the papers, but here is a sister paper Frank and Biggs published in 2012,“Control of Internal Lepidoptera and other insect pests in apple, 2012,” evaluating various insecticides for the control of internal lepidoptera on an experimental plot of Red Delicious apple trees in West Virginia.

Here’s the to-the-point retraction note, which is identical for each paper: Continue reading The “results should not be published:” Company confidentiality agreement squashes two insecticide papers

Oregon public health employee faked 56 infection case reports: ORI

downloadA former employee in the public health division of the Oregon Health Authority committed misconduct in 56 case reports about Clostridium difficile infections in Klamath County, Oregon, as well as in a manuscript submitted to JAMA Internal Medicine and a published report in the Morbidity and Mortality Weekly Report in March, 2012.

Ryan Asherin, previously a Surveillance Officer and Principal Investigator at the OHA, was a busy man. According to the details from a report by the U.S. Office of Research Integrity, Asherin:

Brain paper retracted after university report finds “substantial data misrepresentation”

jneurosci_coverThe Journal of Neuroscience is retracting a 2012 paper on how estrogen produced in the brain shapes the auditory system on the basis of “a report from Northwestern University that describes substantial data misrepresentation” in the paper.

The paper, “Mechanistic Basis and Functional Roles of Long-Term Plasticity in Auditory Neurons Induced by a Brain-Generated Estrogen,” is, according to PubMed, the last one published by its last (and corresponding) author Raphael Pinaud, and first author Liisa Tremere, who were both at Northwestern University at the time. Before his position at Northwestern, Pinaud held positions at the University of Oklahoma and the University of Rochester.

Pinaud and Tremere jointly published a handful of papers on the role of estrogen in the auditory system of the brain starting in 2009, some of which are co-authored by two of the other researchers on the current paper, which has been cited 8 times, according to Thomson Scientific’s Web of Knowledge.

Here’s the retraction notice:

Science retracts troubled gay canvassing study against LaCour’s objections

science coverFollowing revelations of data issues and other problems (which crashed our server last week), Science is retracting a paper claiming that short conversations could change people’s minds on same-sex marriage.

The co-author who admitted to faking the data “does not agree” to the retraction, according to Science. Here’s more from the note: Continue reading Science retracts troubled gay canvassing study against LaCour’s objections

Heart repair study retraction marks second for Mercer University researcher

BasicResCardio_ak12Authors of a study on cardiac repair after heart attack are retracting it from Basic Research in Cardiology because they used “the same samples… to represent two distinct groups on two occasions.”

We find the language of the retraction somewhat confusing, but to the best of our understanding it means that they compared apples to the exact same apples.

The study, published online in 2012, examined the mechanism behind the beneficial effects of a procedure called postconditioning in treating heart attacks. Here’s the retraction notice: Continue reading Heart repair study retraction marks second for Mercer University researcher
