Immunology paper retracted for inappropriate presentation but “no evidence of intentional misconduct”

immun40_4.c1.inddA paper in Immnunity has been retracted after two separate panels determined some of the figures “inappropriately presented” the data but cleared the team of wrongdoing.

However, the original data are now unavailable, according to the notice, so there’s no way to know if the paper’s conclusions are sound.

Here’s the notice for “Suppressors of Cytokine Signaling 2 and 3 Diametrically Control Macrophage Polarization”: Continue reading Immunology paper retracted for inappropriate presentation but “no evidence of intentional misconduct”

A year after ORI report, hematology journal retracts faked paper

bloodA year after an ORI report discredited the work of former University of Washington in Seattle researcher Andrew Aprikyan, one of the papers named in the report has finally been retracted.

Here’s the notice for “Impaired survival of bone marrow hematopoietic progenitor cells in cyclic neutropenia”:  Continue reading A year after ORI report, hematology journal retracts faked paper

Serial figure fakers have expression of concern upgraded to a retraction

Another retraction has appeared up for frequent fliers Jun Li, Kailun Zhang and Jiahong Xia at Huazhong Science and Technology University in Wuhan, China.

We’ve covered them twice before, for a variety of retractions, corrections, and expressions of concern.

The retraction, in Clinical and Experimental Immunology, upgrades an expression of concern published earlier this year, and is the team’s fourth.

Here’s the notice for “CCR5 blockade in combination with rapamycin prolongs cardiac allograft survival in mice”: Continue reading Serial figure fakers have expression of concern upgraded to a retraction

PLOS ONE retraction notice blames deceased author for image manipulation

A 2011 paper in PLOS ONE has been retracted due to “inappropriately assembled” images. The issues, which were highlighted in a correction in TK, are attributed to the corresponding author, Paola Palozza, who has since passed away.

Here’s the notice for “Lycopene Inhibits NF-kB-Mediated IL-8 Expression and Changes Redox and PPARγ Signalling in Cigarette Smoke–Stimulated Macrophages,” which has been cited 33 times, according to Thomson Scientific’s Web of Knowledge: Continue reading PLOS ONE retraction notice blames deceased author for image manipulation

Article about alcohol withdrawal withdrawn

A stumble in data preparation earned a retraction for a paper on delirium tremensalcohol_and_alcoholism, a life-threatening side effect of alcohol withdrawal that spans a wide range of symptoms, including hallucinations and seizures.

Though the initial retraction notice was extremely unhelpful, the author stepped in to give us a better picture of the errors that led to the paper’s demise.

Here’s the notice from Alcohol and Alcoholism about “Biochemical Predictors of Delirium Tremens in Patients in Alcohol Withdrawal”:

Who moved my ants? Species confusion sinks paper on invasive species

“How many and which ant species are being accidentally moved around the world?,” published in 2013, has been retracted because the authors “used a wrong list of species and omitted to include a reference.”

The authors claim that this affected the magnitude of the issue, but not the overall conclusion.

The paper was written up by the press several times, including by the BBC, though according to Thomson Scientific’s Web of Knowledge, it hasn’t been cited.

Here is the notice: Continue reading Who moved my ants? Species confusion sinks paper on invasive species

“Positivity ratio” research now subject to an expression of concern

An expression of concern has been issued for the second of three papers on the idea that, if you have three positive emotions for every negative one, you will be more successful in life.

Psychologist Barbara Fredrickson, of the University of North Carolina, Chapel Hill, has spent the last decade building a brand around this ratio, initially described by a mathematical equation based on fluid dynamics by mathematician Marcial Losada. You can read our coverage of the debunking of that equation, presented in a 1999 paper that has been cited nearly 1,700 times, here.

Nick Brown, co-author with Alan Sokal on the paper that discredited the Losada equation, has written a blog post on the current state of affairs. He also got in touch with us regarding the expression of concern for a 2004 article in American Behavioral Scientist that he had also questioned, “The Role of Positivity and Connectivity in the Performance of Business Teams: A Nonlinear Dynamic Model”: Continue reading “Positivity ratio” research now subject to an expression of concern

Law review paper yanked for lack of attribution despite offer of co-authorship

Sometimes, retractions seem to have a juicy back story, but the explanation proves tantalizingly out of reach.

Such is the case for a law review retraction on a paper about reparations for human rights violations. After someone complained that author Gentian Zyberi “had not done sufficient justice to the substantial contribution” they made, the complainant refused both a co-author credit and a rewrite of the passages in question, insisting instead on a full retraction.

Here’s the notice for “The International Court of Justice and applied forms of reparation for international human rights and humanitarian law violations”: Continue reading Law review paper yanked for lack of attribution despite offer of co-authorship

Patient mix-up sinks prenatal supplement paper

This one seems like an honest mistake: a paper on dietary supplements during pregnancy has been retracted based on an error in data recording.

In the BMC Pregnancy & Childbirth paper, “Folic acid supplementation, dietary folate intake during pregnancy and risk for spontaneous preterm delivery: a prospective observational cohort study,” women for whom the researchers had no data on folic acid supplementation were classified as taking no supplements. Despite the error, the authors claim the overall conclusion remains the same: taking folic acid supplements didn’t protect women from preterm deliveries.

Here’s the retraction notice: Continue reading Patient mix-up sinks prenatal supplement paper

Duplication earns retraction for nanomaterials paper that had already been corrected

Applied_Physics_Letters_cover_imageAfter earning an erratum shortly after publication in 2009, a paper in Applied Physics Letters has now been retracted for the “regrettable mistake” of duplicating an earlier paper by the researchers.

Here’s the notice for “Broadband and omnidirectional antireflection from conductive indium-tin-oxide nanocolumns prepared by glancing-angle deposition with nitrogen:” Continue reading Duplication earns retraction for nanomaterials paper that had already been corrected
