Authors used wrong dataset in study on shock therapy, exercise in depression

J psych resA psychiatric journal has pulled a 2014 paper that found electroconvulsive therapy and exercise helped people with depression, after the authors determined they had mistakenly analyzed the wrong data.

According to the retraction notice from the Journal of Psychiatric Research, the researchers had “erroneously analyzed” data from a previous study they had published the year before.

Here’s more from the note for “Electroconvulsive therapy and aerobic exercise training increased BDNF and ameliorated depressive symptoms in patients suffering from treatment-resistant major depressive disorder:” Continue reading Authors used wrong dataset in study on shock therapy, exercise in depression

2014 ORI finding results in retraction of cancer paper with manipulated images

Mol Can TherA paper flagged in an Office of Research Integrity notice more than one year ago has finally been retracted.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:

Investigation prompts 5th retraction for cancer researcher for “unresolvable concerns”

3.coverAn investigation at the University of New South Wales in Australia has led to a fifth retraction for a cancer researcher long accused of misconduct, due to “unresolvable concerns” with some images.

As we reported in December, UNSW cleared Levon Khachigian of misconduct, concluding that his previous issues stemmed from “genuine error or honest oversight.” Now, Circulation Research is retracting one of his papers after an investigation commissioned by UNSW was unable to find electronic records for two similar images from a 2009 paper, nor records of the images in original lab books.

Again, the retraction note affirms that this is not a sign of misconduct:

UNSW has not attributed any instance of research misconduct or responsibility for the unavailability of the original data to Professor Khachigian or to any of the authors of the publication.

Here’s the retraction note in full for “Angiotensin II-Inducible Smooth Muscle Cell Apoptosis Involves the Angiotensin II Type 2 Receptor, GATA-6 Activation, and FasL-Fas Engagement:” Continue reading Investigation prompts 5th retraction for cancer researcher for “unresolvable concerns”

After hesitating, Science retracts chemistry paper against authors’ wishes

F1.mediumToday, Science has retracted a 2004 paper that’s been under scrutiny for years, despite the authors’ objections.

This paper has a long backstory: Recently, a report from the National Science Foundation’s Office of Inspector General surfaced that announced the agency had cut off the authors from funding. Last month, editor Marcia McNutt told us that the journal planned to retract the paper as soon as possible. Then, on January 21st, “just as we were going to press with the retraction,” said McNutt, the authors submitted a correction, which Science wanted to take some time to consider.

Now, the paper has a retraction note, against the wishes of authors Bruce Eaton and Dan Feldheim, currently at the University of Colorado.

Here it is the retraction note:

Data irregularities force author to retract three solar cell papers

no spine minimum. full size. Editor: Jon JEM: Esther RTP: Bryan Nolte TOC image

An engineer has retracted three papers on a method for making nanoscale materials that are useful in solar cells.

The papers, all published in ACS Applied Materials & Interfaces, contain irregularities in data, and one includes images “which have been published elsewhere and identified with different samples,” according to the note.

The first author on all three papers is Khalid Mahmood, who — according to the bio from a talk he gave last year on efficient solar cells — is currently a postdoc at King Abdullah University of Science and Technology in Saudi Arabia. He did the work in the retracted papers while a student at the Korea Advanced Institute of Science and Technology, where, according to the bio, he completed his PhD in two years.

Here’s the retraction note for the first paper (which also contains a typo in the title — “electrospay”)

Makeup use linked to testosterone levels? Not so fast, says retraction

Psych SciA psychology journal is retracting a 2015 paper that attracted press coverage by suggesting women’s hormone levels drive their desire to be attractive, after a colleague alerted the last author to flaws in the statistical analysis.

The paper, published online in November, found women prefer to wear makeup when there is more testosterone present in their saliva. The findings were picked up by various media including Psychology Today (“Feeling hormonal? Slap on the makeup”), and even made it onto reddit.com.

However, upon discovering a problem in the analysis of the data, the authors realized that central finding didn’t hold up, according to Psychological Science‘s interim editor, Stephen Lindsay: Continue reading Makeup use linked to testosterone levels? Not so fast, says retraction

2001 Fujii papers retracted — finally. What took so long?

BJO

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: Continue reading 2001 Fujii papers retracted — finally. What took so long?

Another case of plagiarism in papers published only months apart

pageHeaderTitleImageRemember when we recently found PLOS ONE had published two papers with “substantial overlap” from two different groups, that were edited around the same time? Well, we have discovered another similarly perplexing case of plagiarism in two studies published only months apart. But in this instance, we have a possible explanation for how two groups of authors from different institutions could report a similar experiment and data, and even use some of the same text.

It also concerns a paper focusing on cancer biology — in this case, it’s a 2014 paper retracted by Clinical and Investigative Medicine after editors learned that it contained many similarities to a study published only a handful of months before in Tumour Biology.

According to an email from an author on the retracted paper to the editor, Continue reading Another case of plagiarism in papers published only months apart

“There was no effort to commit fraud,” says EMBO awardee under investigation

A recent recipient of an early career award now under investigation by granting agency EMBO told us today that last week’s retraction in Nature Genetics stemmed solely from an “embarrassing error,” and she hopes to republish the data in a new paper.

Last week was rough for Sonia Melo: Nature Genetics retracted one of her papers, and the European Molecular Biology Organization (EMBO) announced it was investigating the papers that formed the basis of her application. The retraction was of “A TARBP2 mutation in human cancer impairs microRNA processing and DICER1 function,” which has been cited 235 times, according to Thomson Scientific’s Web of Knowledge.

Melo’s Installation Grant from EMBO was announced in December, and consists of 50,000 Euros annually for three to five years. She is currently based at the University of Porto, in Portugal.

Melo contacted us today to defend her record: Continue reading “There was no effort to commit fraud,” says EMBO awardee under investigation

Letter calls for retraction of yoga weight loss paper

IntJYoga_2016_9_1A paper concluding that a specific series of yoga poses is effective at promoting weight loss in obese women has a call for retraction in a letter to the editor of the International Journal of Yoga. 

The study followed 87 women for 8 weeks as they completed a regular routine of  yoga, circuit training, or walking on a treadmill. “Suryanamaskar: An equivalent approach towards management of physical fitness in obese females” concludes that

All three methods were effective in weight and physical fitness management.

But a group of heath researchers at the University of Alabama at Birmingham led by David Allison failed to replicate the statistical tests on some of the data. In a recent letter to the editor, “Unsubstantiated conclusions from improper statistical design and analysis of a randomized controlled trial,” they express skepticism about the paper’s claims, and ask the journal to retract it:
