Rui Curi — the Brazilian scientist who threatened to sue the now-shuttered Science-Fraud.org site for criticizing his work — has rung up his second retraction, this one for a paper that he corrected earlier this year.
Here’s the Journal of Endocrinology notice, whose headers and language are a bit confusing, understandably, because it is retracting two things, a correction and the original paper: Read the rest of this entry »
Back in January, we wrote about the retraction of a paper in the International Journal of Radiation Oncology *Biology* Physics, the first from that journal in its 38-year history.
At the time, the journal’s new editor, Anthony Zietman, of Mass General, told us that he was working on a second retraction. That one has arrived.
The paper, “High-Dose Conformal Radiotherapy Reduces Prostate Cancer–Specific Mortality: Results of a Meta-analysis,” came from a team of radiation oncologists in Brazil, and was published last August.
According to the retraction notice:
The Journal of Endocrinology has run a correction for a paper by Rui Curi, the Brazilian scientist whose lawyers threatened Science-Fraud.org after the site ran a number of posts critical of Curi’s work.
Here’s the correction for “Effects of moderate electrical stimulation on reactive species production by primary rat skeletal muscle cells: Cross-talk between superoxide and nitric oxide production,” in the Journal of Cellular Physiology: Read the rest of this entry »
A few weeks ago, we reported on the shutdown of Science-Fraud.org, a site dedicated to highlighting problems with scientific papers, thanks to legal threats. At the same time, we noted that Rui Curi, one of the authors whose work had been questioned — and whose lawyers had sent the site a cease-and-desist letter — ended up retracting a paper the site had questioned.
Now, Curi has corrected another paper that featured on Science-Fraud.org. Here’s the notice: for “Comparative toxicity of oleic and linoleic acid on human lymphocytes,” which was originally published in Life Science in 2006: Read the rest of this entry »
A 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, Read the rest of this entry »
The International Journal of Nanomedicine is retracting a paper it published in June that appears to contain an impressive amount of misappropriated text and figures.
The article, “Particokinetics: computational analysis of the superparamagnetic iron oxide nanoparticles deposition process,” came from a group at the Hospital Israelita Albert Einstein, in São Paulo, Brazil, led by Walter Cárdenas. According to the notice: Read the rest of this entry »
In late May, Ivan was invited to Brazil to take part in the Second Brazilian Meeting on Research Integrity, Science and Publication Ethics(II BRISPE). Organized by the Medical Biochemistry Institute (IBqM/UFRJ) & Alberto Luiz Coimbra Institute for Graduate Studies and Research in Engineering (COPPE/UFRJ), the meeting traveled from Rio de Janeiro to São Paulo to Porto Alegre over the course of several days.
One of the goals of the whirlwind meeting, which brought together researchers, administrators, funding agencies, and experts in scientific integrity from around the world, was to produce a Joint Statement on Scientific Integrity. That statement, into which Ivan had input, has now been published, so we thought we’d post links to it in English, Portuguese, and Spanish and check in with Sonia Maria Ramos Vasconcelos, one of the organizers of the meeting.

In August, we reported on an upcoming retraction of a paper in The Journal of Insect Behavior by Leonardo Gomes, a Brazilian forensic entomologist. At the time, one of the journal’s editors, Thomas Payne, told us that Gomes and his co-authors had been informed that “Dispersal and Burial Behavior in Larvae of Chrysomya megacephala and Chrysomya albiceps (Diptera, Calliphoridae),” would be retracted.
