MD Anderson’s Bharat Aggarwal threatens to sue Retraction Watch

Bharat Aggarwal, an MD Anderson researcher under investigation by his institution, has threatened to sue us.

Today, we received a letter from the Houston firm of Paranjpe & Mahadass LLP telling us to pull every post related to their client off our site within 20 days, or they’d “file a lawsuit against” us on his behalf.

On what grounds? According to the March 26 letter, which we have posted here in its entirety: Continue reading MD Anderson’s Bharat Aggarwal threatens to sue Retraction Watch

Alirio Melendez notches retractions 10 and 11

Former 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

New Mexico obstetrics researcher violated research subject protocols: Retraction notice

Laurence Cole, an obstetrics researcher at the University of New Mexico, made an appearance on this blog in November 2011 after the American Journal of Obstetrics & Gynecology published a remarkably heavy-handed retraction of one of his papers.

Shortly after, we learned that the retraction was preceded by a strongly-worded letter from an attorney representing a company that had been miffed by the content of Cole’s article (the issue involved the effectiveness of commercially-available pregnancy tests, and Cole’s failure to adequately disclose a past relationship with the aggrieved company’s competitor). That letter read, in part: Continue reading New Mexico obstetrics researcher violated research subject protocols: Retraction notice

Kenji Okajima retraction count grows to five

We’ve been following the case of Kenji Okajima, a professor at Nagoya City University in Japan who was suspended for six months following an investigation into work in his lab. Bits of the story — including at least one other university investigation, and scrutiny of Okajima’s colleagues, one of whom was fired — have been dribbling out for almost two years since a retraction notice in the Journal of Neuroscience.

In all, it looks as Nagoya found evidence of misconduct in 19 papers. The Journal of Neuroscience retraction appeared in 2011, and another showed up in the Journal of Immunology last year. Now there are three more: One in Translational Research and two in Blood.

Here’s the notice from Translational Research: Continue reading Kenji Okajima retraction count grows to five

One in twelve Belgian medical scientists admits having “made up and/or massaged data”: Survey

A recently released survey of Belgian scientists suggests that Flemish medical researchers admit to having made up or massaged data more often than their counterparts around their world.

The survey, by the Dutch science magazine Eos with the help of Joeri Tijdink, of VU University Medical Center in Amsterdam, and the Pascal Decroos Fund for Investigative Journalism, found that Continue reading One in twelve Belgian medical scientists admits having “made up and/or massaged data”: Survey

Cardiologist accused of misconduct strikes back in a journal

Retraction Watch readers may recall the case of Don Poldermans, a prominent Dutch cardiology researcher who left a research position in late 2011 amid an investigation into his work. In a letter in the American Journal of Medicine titled “Scientific Fraud or a Rush to Judgement?” Poldermans — three of whose papers are subject to Expressions of Concern — tries to set the record straight, something he has tried to do before.
