Irony? Paper by author whose attorneys sent cease-and-desist letter to Science Fraud retracted

j lipid researchA Brazilian author whose attorneys were the first to send the now-shuttered Science Fraud site a cease-and-desist letter has now had a paper retracted.

As Retraction Watch readers may know, Science Fraud shut down earlier this week in response to legal threats. Those threats were preceded by a cease-and-desist letter last month from attorneys for Rui Curi, of the University of Sao Paulo.

Curi’s work had been scrutinized by Science Fraud in a number of posts, with allegations of duplicated bands and re-used Western blots. With a gnawing suspicion that some of our more erudite readers will take issue with our use of “irony” here, Continue reading Irony?

Retraction three for Milena Penkowa, for diabetes-exercise study

diabetesMilena Penkowa, the former University of Copenhagen scientist found by her university to have embezzled grant funds and to have possibly committed misconduct in 15 papers, has another retraction.

An international panel released its findings in July, as Nature reported then: Continue reading Retraction three for Milena Penkowa, for diabetes-exercise study

Retractions three and four for Hopkins cancer biomarker group

ccrA group of cancer researchers formerly centered at Johns Hopkins have retracted two more studies. The previous two retracted papers — one of which was the focus of a lawsuit — were about prostate cancer, while the new retractions are of papers about colon cancer.

Here’s the notice for one paper: Continue reading Retractions three and four for Hopkins cancer biomarker group

Scientists retract paper because they’re “not satisfied with the quality of some of the data”

antiox and redoxA group of smoking researchers — no, not scientists who are on fire; scientists who study the effects of tobacco smoke — has retracted a 2009 article after deciding that they were no longer “satisfied with the quality of the data.”

The paper, “Cigarette Smoke–induced Oxidative/Nitrosative Stress Impairs VEGF- and Fluid Shear Stress–Mediated Signaling in Endothelial Cells,” came from the lab of Irfan Rahman, a lung disease expert at the University of Rochester. It appeared online in 2009 in Antioxidants & Redox Signaling, which will be familiar to readers watching the case of Dipak Das. 

As the notice explains: Continue reading Scientists retract paper because they’re “not satisfied with the quality of some of the data”

NUS: Melendez committed “serious scientific misconduct,” but don’t expect to get any details

alirio_melendezAlirio Melendez, a former National University of Singapore immunologist whose story we’ve been following here since a retraction in September of last year, committed misconduct on an “unprecedented” scale, according to the university, involving more than 20 papers.

Nature’s Richard van Noorden has the scoop:

After a 19-month investigation, the National University of Singapore (NUS) today says that it has determined that one of its former scientists, the immunologist Alirio Melendez, has committed “serious scientific misconduct”.  The university found fabrication, falsification or plagiarism associated with 21 papers, and no evidence indicating that other co-authors were involved in the misconduct, it says.

Melendez has retracted five papers so far, as we’ve reported, but NUS wouldn’t give the whole list. They tell Nature: Continue reading NUS: Melendez committed “serious scientific misconduct,” but don’t expect to get any details

Concern — in triplicate — arrives for Poldermans papers

Jacc1212coverThe Journal of the American College of Cardiology, or JACC, has issued expressions of concern for three papers by Don Poldermans, the Dutch cardiologist who was fired earlier this year amid allegations of misconduct.

Cardiobrief’s Larry Husten had the story first.

The, um, heart of the matter is that neither the investigators at Erasmus Medical Center, Poldermans’ former institution, nor the JACC editors, can say whether the researchers conduct rose to the level of fabricating data. As the Notice of Concern states: Continue reading Concern — in triplicate — arrives for Poldermans papers

Funding agency sanctions Bulfone-Paus and former postdoc

Retraction Watch readers may recall the case of Silvia Bulfone-Paus, a researcher at Germany’s Research Center Borstel who was a frequent subject of posts in the early days of this blog. Bulfone-Paus has had to retract 13 papers amid investigations into allegations of image manipulation.

To briefly recap: In May 2010, several months after concerns had first been raised, Borstel let the DFG (German Research Foundation) know about the allegations, because they had funded the work. A November 2010 report from Borstel said that the allegations had merit, blaming two of Bulfone-Paus’s postdocs but criticizing how she supervised them. As the DFG notes in a summary of its findings on the case, posted late last week: Continue reading Funding agency sanctions Bulfone-Paus and former postdoc

After retracted study’s cited, editors ask, “time to add scientific integrity to the downside of print on paper?”

JneuranesAs we — and others — have written, retracted articles don’t necessarily creep off to some little island somewhere never to be heard from again. After all, the electronic versions of about a third of retracted papers aren’t marked as retracted. Sometimes, like Napoleon, those papers return from exile to wreak havoc: They get cited as if they had never been retracted.

To wit: The Journal of Neurosurgical Anesthesiology has published a letter to the editor regarding a 2012 article by a group of Italian researchers. The topic of the paper in question was “Perioperative pregabalin for postoperative pain control and quality of life after major spinal surgery.”

That happens to have been an area of interest for one Scott Reuben, a Massachusetts anesthesiologist and pain specialist turned federal inmate who was, Continue reading After retracted study’s cited, editors ask, “time to add scientific integrity to the downside of print on paper?”

“Additionally, the authors were unable to identify” co-author: Another retraction for Lemus

env microWe’ve been following the case of Jesús A. Lemus, the Spanish veterinary researcher with five retractions and two expressions of concern under his belt so far for suspected data fabrication and including a fake author on his papers.

Yes, a fake author. When this story first broke, El Pais called Javier Grande a ” ghost with a good academic background with at least six scientific publications in international journals.”

Grande’s — and Lemus’s — publication count declined by one more yesterday, as Environmental Microbiology retracted a 2007 paper: Continue reading “Additionally, the authors were unable to identify” co-author: Another retraction for Lemus

Retraction three for Dirk Smeesters
