And then there were eight: Three more retractions for Alirio Melendez, all in the Journal of Immunology

alirio_melendezAlirio Melendez, who has already retracted five papers and was found by one of his former universities to have committed misconduct on more than 20, has three more retractions.

Here’s the notice for “Antisense Knockdown of Sphingosine Kinase 1 in Human Macrophages Inhibits C5a Receptor-Dependent Signal Transduction, Ca2+ Signals, Enzyme Release, Cytokine Production, and Chemotaxis,” cited 68 times, according to Thomson Scientific’s Web of Knowledge: Continue reading And then there were eight: Three more retractions for Alirio Melendez, all in the Journal of Immunology

Another correction for Rui Curi, whose legal threats helped force shutdown of Science Fraud site

joeThe 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 notice for “Non-esterified fatty acids and human lymphocyte death: a mechanism that involves calcium release and oxidative stress”: Continue reading Another correction for Rui Curi, whose legal threats helped force shutdown of Science Fraud site

Rui Curi, the Brazilian scientist whose lawyers’ threats helped force the shutdown of Science-Fraud.org, has corrected another paper criticized by the site.

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: Continue reading Author whose lawyers threatened Science Fraud corrects another paper

Musical figures: PNAS paper corrected with version of “intentionally contrived and falsified” Nature figure

pnasOne of the two corrections recommended by a McGill committee for work by Maya Saleh and colleagues has appeared, in the Proceedings of the National Academy of Sciences (PNAS).

As we reported last month, the committee found that

two figures in [a] Nature paper had been “intentionally contrived and falsified.” One of those figures was duplicated in a PNAS paper, which also contained an image that  had incorrectly labeled some proteins.

The committee recommended that both of the papers be corrected, and the PNAS correction  for “Confinement of caspase-12 proteolytic activity to autoprocessing” reads as follows: Continue reading Musical figures: PNAS paper corrected with version of “intentionally contrived and falsified” Nature figure

Paper linking cell phones during pregnancy to behavior problems in mice corrected

scientificreportsThe authors of a study published last year looking at the effects of cell phone exposure on mice in utero have corrected a figure after it was questioned. New experiments, they write, confirm the original conclusions they drew from the figure.

Here’s the corrected figure from the paper in Scientific Reports, published by Nature Publishing Group: Continue reading Paper linking cell phones during pregnancy to behavior problems in mice corrected

First author of recently retracted paper has another corrected, in J Ag Food Chem

jafcau_v061i004.inddA paper that shares a first author with a paper retracted in December has been corrected.

Late last year, we reported on a retraction in Antioxidants & Redox Signaling (ARDS) by Indika Edirisinghe, who was at the University of Rochester when the original paper was published, and colleagues. On January 17, the Journal of Agricultural and Food Chemistry published a correction to “Effect of Black Currant Anthocyanins on the Activation of Endothelial Nitric Oxide Synthase (eNOS) in Vitro in Human Endothelial Cells,” on which Edirisinghe is also first author.

His affiliation on that paper, originally published in July 2011, is the Illinois Institute of Technology. Here’s the correction: Continue reading First author of recently retracted paper has another corrected, in J Ag Food Chem

An associate professor at Montreal’s McGill University is correcting two papers, one of them in Nature, after a university committee found evidence of falsification, Retraction Watch has learned.

Concerns had been raised about four papers by Maya Saleh and colleagues: Continue reading McGill committee says Nature figures were “intentionally contrived and falsified”

Correction for MD Anderson’s Aggarwal, cancer researcher whose work is under investigation

jmm113coverBharat Aggarwal, the highly cited MD Anderson Cancer Center researcher who has confirmed to us that his work is under investigation by the institution, has a correction of his work in the Journal of Molecular Medicine. Troubled images are to blame — as they have been in previous retractions, and at least one other correction, of Aggarwal’s papers.

The paper, “Celastrol suppresses invasion of colon and pancreatic cancer cells through the downregulation of expression of CXCR4 chemokine receptor,” was published in December 2010 and cited 15 times since, according to Thomson Scientific’s Web of Knowledge.

Here’s the notice: Continue reading Correction for MD Anderson’s Aggarwal, cancer researcher whose work is under investigation

Curi-us: Author whose lawyers threatened Science Fraud corrects a paper the site criticized

Rui Curi

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: Continue reading Curi-us: Author whose lawyers threatened Science Fraud corrects a paper the site criticized
