University of Lisbon investigation that spawned neuroscience retractions found no evidence of misconduct

j neuroscienceYesterday, we reported on two retractions in the Journal of Neuroscience whose notices referred to a University of Lisbon report that had determined there was  “substantial data misrepresentation” in the original articles.  The notice didn’t say anything about misconduct, but when we see “misrepresentation,” we tend to think — as do many others — that there had been funny business.

But we heard back this morning from the senior author of the study, Ana M. Sebastião, and there’s a lot more to this story. It turns out that the University of Lisbon committee that wrote the report concluded, unanimously, that Continue reading University of Lisbon investigation that spawned neuroscience retractions found no evidence of misconduct

University of Lisbon finds “substantial data misrepresentation;” two Journal of Neuroscience papers retracted

j neuroscienceA University of Lisbon investigation has prompted two retractions in the Journal of Neuroscience.

The papers share a few authors, including senior author Ana M. Sebastião. Here’s the notice for the first paper: Continue reading University of Lisbon finds “substantial data misrepresentation;” two Journal of Neuroscience papers retracted

Leading cancer researcher retracts 2003 paper for “inappropriate presentation”

cancer cellOne of the world’s leading cancer researchers, MIT’s Robert Weinberg, has retracted a decade-old paper after finding out it contained errors.

Here’s the notice for “Ras Modulates Myc Activity to Repress Thrombospondin-1 Expression and Increase Tumor Angiogenesis,” a paper originally published in Cancer Cell in 2003: Continue reading Leading cancer researcher retracts 2003 paper for “inappropriate presentation”

Eric Smart, who as we reported in November was sanctioned by the Office of Research Integrity (ORI) for faking dozens of images in ten papers and seven grants over the past decade, has had his first retraction.

Here’s the December 24 notice, from PNAS: Continue reading First retraction for Eric Smart, who faked dozens of images, appears in PNAS

Authors retract Diabetes paper after submitting it “without knowledge of inherent errors”

diabetesA group of neuroscientists has retracted a paper published earlier this last year in Diabetes after realizing that a figure that took up a whole page of the paper may not have been quite right.

Here’s the notice for “Blockade of receptor for advanced glycation end products in a model of type 1 diabetic leukoencephalopathy”: Continue reading Authors retract Diabetes paper after submitting it “without knowledge of inherent errors”

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

Paul Muchowski, a neuroscience researcher at the Gladstone Institute of Neurological Disease in San Francisco, faked data in multiple grant applications, according to findings released today by the Office of Research Integrity (ORI).

In a funded NIH grant, R01 NS054753-06A1, and two submitted grant applications, R01 NS054753-06 and R01 NS047237-06, ORI says that Muchowski “knowingly and intentionally” committed “research misconduct by falsifying and fabricating data” as follows:

ORI sanctions former Texas Tech postdoc for falsification, fabrication, plagiarism

biomed chromatographyThe Office of Research Integrity (ORI) has sanctioned a former Texas Tech postdoc for using data that had actually been generated before he joined the lab in a paper as if it were new.

Shuang-Qing Zhang, according to today’s announcement by the ORI, “engaged in research misconduct by the falsification and fabrication of plagiarized data” in a paper he claimed to have written with his supervisor, Reza Mehvar, “Determination of dextra-methylprednisolone conjugate with glycine linker in rat plasma and liver by high-performance liquid chromatography and its application in pharmacokinetics,” first published online in Biomedical Chromatography in 2009. [see update at end of post]

The work was supported by the National Institute of General Medical Sciences (NIGMS), National Institutes of Health (NIH), grant R01 GM069869. The ORI found that Zhang had: Continue reading ORI sanctions former Texas Tech postdoc for falsification, fabrication, plagiarism

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”

Stem cell retraction leaves grad student in limbo, reveals tangled web of industry-academic ties

stem cells developmentA contested retraction in Stem Cells and Development has left the Queensland University of Technology (QUT) graduate student who fought for it in limbo, uncertain if he will earn his PhD. And many of those who didn’t want the paper retracted have a significant financial interest in a company whose work was promoted by the research — despite any lack of disclosure in the now-retracted paper.

Here’s the notice: Continue reading Stem cell retraction leaves grad student in limbo, reveals tangled web of industry-academic ties
