Trial irregularities earn Lancet study of potential weight loss drug tesofensine Expression of Concern

logo_lancetA potential weight loss drug has been dealt what could be a serious setback after regulators found problems at two trial sites.

While awaiting a final report, The Lancet, which published a study of the drug, tesofensine, has issued an Expression of Concern: Continue reading Trial irregularities earn Lancet study of potential weight loss drug tesofensine Expression of Concern

Update on “greatly enhanced” photonics paper, with two corrections — one by journal, one by us

nature photonicsLast month we wrote about a paper in Nature Photonics that, because of a measurement error, had to be retracted.

It turns out that wasn’t the only problem with the article — but we’re afraid that the glitch requires us to issue a correction.

The article, “Greatly enhanced continuous-wave terahertz emission by nano-electrodes in a photoconductive photomixer,” has listed Aaron Danner as the last — and, we’d assumed — senior author of the paper. But as Danner pointed out to us, that was a mistake by Nature Photonics.

Alirio Melendez notches retractions 10 and 11

jbcmarch13coverFormer National University of Singapore and University of Liverpool scientist Alirio Melendez has two more of the 20-something retractions suggested by the investigations into his work. Both appear in the Journal of Biological Chemistry.

Here’s the notice for “FcγRI-triggered generation of arachidonic acid and eicosanoids requires iPLA2 but not cPLA2 in human monocytic cells:” Continue reading Alirio Melendez notches retractions 10 and 11

ORI rules in longstanding University of Washington misconduct case

Andrew Aprikyan

A case of alleged misconduct at the University of Washington in Seattle may finally be over. The Office of Research Integrity released its findings following an investigation into the work of Andrew Aprikyan, a former hematology researcher at the university.

The Aprikyan case has dragged on for a decade. In 2010, the university fired the scientist after a court denied his appeals based on allegations that they had denied him due process. As the Seattle Times reported at the timeContinue reading ORI rules in longstanding University of Washington misconduct case

Editor on retraction details: “I do not think this is the business of anyone but our journal, please”

early education developmentWhose business are the reasons behind a retraction?

Our readers will no doubt know by now that we think they’re basically everyone’s — at least if journals want us to believe that they’re interested in maintaining the integrity of the scientific record. But not all editors seem to agree. Hank Edmunds, for example, didn’t in early 2011, telling us, “It’s none of your damn business.” A chemistry journal editor said, in a similar vein, “the purpose of keeping these retraction notices slim is not to produce too much detail.”

Now, a psychology journal editor joins those ranks. Here’s the notice in question: Continue reading Editor on retraction details: “I do not think this is the business of anyone but our journal, please”

Environmental scientists call for retraction of oil industry-funded paper on benzene exposure

carcinogenesis 13A paper suggesting that scientists may want to rethink what levels of benzene are carcinogenic has led to a sharp exchange in the journal that originally published it.

In 2006, Stephen Rappaport, of UNC-Chapel Hill, and colleagues, published a paper that began by saying that benzene

is an important industrial chemical that is also emitted into the air from gasoline, engine exhausts and combustion of organic materials (including cigarette smoke) (1,2). Occupational exposures to benzene at air levels greater than ∼10 p.p.m., have long been linked to hematotoxicity and to acute myelogenous leukemia (35). A recent report of hematotoxic effects in workers exposed to benzene <1 p.p.m. (6) has raised additional concerns regarding the health consequences of low exposures to this contaminant.

The authors conclude: Continue reading Environmental scientists call for retraction of oil industry-funded paper on benzene exposure

Vacuum retracts paper on nanorods for plagiarism, image manipulation

vacuumWhat’s that sucking sound you hear from the journal Vacuum? Why, a retraction, of course.

The journal is pulling a 2012 paper by a group of researchers from India who stole images and used them in misleading ways — that’s data fabrication, kids.

Here’s the retraction notice for the article, titled “Microwave synthesis, characterization and humidity sensing properties of single crystalline Zn2SnO4 nanorods”:

Arsenic-in-the-water paper with “interesting data” first corrected, now retracted

jchcoverNote (4/9/13): John McArthur contacted us with a few corrections, which we have made below.

The Journal of Contaminant Hydrology has retracted a 2008 paper by a group of Indian scientists for plagiarism and the failure to adequately reference their sources.

What makes this case somewhat unusual is that the journal allowed the authors to issue a correction (of the mega variety) attempting to acknowledge the problems, but then evidently decided that the patient was too sick to live — and that part of the disease was iatrogenic.

Here’s the retraction notice for the article, titled “Hydrogeochemical behavior of arsenic-enriched groundwater in the deltaic environment: Comparison between two study sites in West Bengal, India”:

Second retraction appears for University of Wisconsin neuroscientist who faked images

brain researchA University of Wisconsin scientist who was found by the Office of Research Integrity (ORI) to have faked data in two papers, has had a second study retracted.

Here’s the notice: for “Secretory phospholipase A2 IIA is up-regulated by TNF-α and IL-1α/β after transient focal cerebral ischemia in rat,” by Rao Adibhatla and colleagues and originally published in Brain Research in February 2007: Continue reading Second retraction appears for University of Wisconsin neuroscientist who faked images
