A paper flagged in an Office of Research Integrity notice more than one year ago has finally been retracted. According to the notice, the paper includes images manipulated by author H. Rosie Xing, a former University of Chicago cancer researcher.
The main conclusions of the paper are affected by the ORI finding, according to the retraction note from Molecular Cancer Therapeutics. But otherwise, the note contains information that was available in the ORI finding, published in December 2014.
“Pharmacologic Inactivation of Kinase Suppressor of Ras1 Sensitizes Epidermal Growth Factor Receptor and Oncogenic Ras-Dependent Tumors to Ionizing Radiation Treatment” has been cited seven times, according to Thomson Scientific’s Web of Knowledge — twice since the ORI finding came out.
The retraction note explains which images were affected by the manipulation:
Nearly four years after an analysis of more than 160 papers by Yoshitaka Fujii concluded the chances the data were authentic were infinitesimally small, the British Journal of Ophthalmology has decided to formally retract one of the papers included in that review.
The name Yoshitaka Fujii should ring a bell — an alarm bell, in fact — for our readers. He’s firmly listed in the number one spot on our leaderboard, with more than 180 retractions.
The recently retracted paper — “Ramosetron compared with granisetron for the prevention of vomiting following strabismus surgery in children” — has been included in that retraction total for years, because it was part of a seminal 2012 analysis by J.B. Carlisle that put the odds of data occurring naturally in some of Fujii’s papers at: Read the rest of this entry »
The online news site is retracting and correcting several articles by former staff writer Juan Thompson, who was employed there from November 2014 until last month.
Following questions from outside experts, a retraction of a related paper, a university investigation and a court case, The Lancet has decided to retract a 1992 paper by Ranjit Kumar Chandra, the self-proclaimed “father of nutritional immunology.”
In a lengthy retraction note included in the January 30 issue, the journal explains that:
the balance of probabilities in our judgment is that the reliability of the 1992 Lancet paper by Chandra can no longer be assured.
Chandra is objecting to the retraction.
This retraction was a long time coming, so sit back and relax as we fill in the backstory. Read the rest of this entry »
An Ontario court has quashed part of a misconduct finding against a prominent husband and wife team by the University Health Network in Toronto.
Last year, we reported that Sylvia Asa had stepped down from her position as Program Medical Director of the Laboratory Medicine Program at the UHN — the largest hospital diagnostic laboratory in Canada — after an investigation uncovered evidence of falsified data in two papers co-authored with her husband, Shereen Ezzat. Both of their research labs were also suspended as a result. The researchers subsequently appealed the decision.
Friday Sunday, the Toronto Star reported that the court had set aside the finding of falsification, but upheld a finding of misconduct in the form of material non-compliance. It asked UHN to review the sanctions against both researchers, and cover their legal fees of $20,000.
Here’s the conclusion from the decision:
A nutrition journal is retracting a paper about potential dangers of eating food containing genetically modified organisms (GMOs) for duplicating a figure, as news stories from Italy are reporting accusations that the last author falsified some of his research.
In the paper, Federico Infascelli, an animal nutrition researcher at the University of Naples, and his colleagues showed modified genes could wind up in the blood and organs of baby goats whose mothers ate GM soybeans. According our Google Translate version of an article by Italian newspaper La Repubblica, an investigation suggests that Infascelli has manipulated images to suggest GMOs are harmful. He could face fines and be suspended from the university.
La Repubblica reports that a committee appointed by the rector of the university, Gaetano Manfredi, found errors in Infascelli’s data that suggested he had manipulated the results to show GMOs were harmful.
One paper by Infascelli has been retracted from Food and Nutrition Science, “Gamma-Glutamyl Transferase Activity in Kids Born from Goats Fed Genetically Modified Soybean.” The retraction note says the paper was pulled for duplication:
A paper on how plants respond to bacteria has an invader of its own — data manipulation.
The “irregularities and inappropriate data manipulation” were found in a figure produced by the first author, Ching-Wei Chen, whose LinkedIn page lists him as a student at the National Taiwan University. The authors were unable to replicate the results in the figure, according to the note.
The authors are doing more experiments to verify the main conclusion of the 2014 paper, “The Arabidopsis Malectin-Like Leucine-Rich Repeat Receptor-Like Kinase IOS1 Associates with the Pattern Recognition Receptors FLS2 and EFR and Is Critical for Priming of Pattern-Triggered Immunity,” published in The Plant Cell.
The retraction note explains the what happened in more detail:
Second of 3 retractions appears for biologist, the result of “a substantial number of falsifications”
First author Sudarsanareddy Lokireddy, now apparently a research fellow at Harvard, did not agree to the retraction, the result of “a substantial number of falsifications.”
In December, we covered the results of the NTU investigation, where Lokireddy used to work. During that investigation, he admitted to falsifying data, Research Integrity Officer Tony Mayer told us. The end result: three retractions.
One of those papers was retracted by Cell Metabolism in December. The second paper, published in Molecular Endocrinology, has been cited 52 times, according to Thomson Scientific’s Web of Knowledge. The retraction note explains which figures were falsified:
An appeals court has affirmed the stiff prison sentence for Dong-Pyou Han, the former Iowa State University researcher who faked the results of an HIV vaccine experiment in rabbits. Read the rest of this entry »
The National Science Foundation will no longer fund a pair of chemists who “recklessly falsified data,” according to a report from the NSF’s Office of Inspector General, unless they “take specific actions to address issues” in a 2004 Science paper.
That paper is going to be retracted as soon as possible, Science told us. The co-authors that the NSF reprimanded are Bruce Eaton and Dan Feldheim, now at the University of Colorado at Boulder; they have been under scrutiny since 2008, when an investigation at North Carolina State University, their former employer, found that the Science paper contained falsified data.
The paper, “RNA-Mediated Metal-Metal Bond Formation in the Synthesis of Hexagonal Palladium Nanoparticles,” has been cited 138 times.
Science Editor in Chief Marcia McNutt told us today that a retraction is in the works:
