PLOS ONE retraction notice blames deceased author for image manipulation

A 2011 paper in PLOS ONE has been retracted due to “inappropriately assembled” images. The issues, which were highlighted in a correction in TK, are attributed to the corresponding author, Paola Palozza, who has since passed away.

Here’s the notice for “Lycopene Inhibits NF-kB-Mediated IL-8 Expression and Changes Redox and PPARγ Signalling in Cigarette Smoke–Stimulated Macrophages,” which has been cited 33 times, according to Thomson Scientific’s Web of Knowledge: Continue reading PLOS ONE retraction notice blames deceased author for image manipulation

Anesthesiologist “con man” apologizes for faking cover-up charges against Australian university

It’s not uncommon for scientists accused of wrongdoing — especially if they’re fired for it — to attempt to muddy the waters by claiming that they are being framed because they had threatened to blow the whistle on others.  Some of those stories have more than a grain of truth to them.

Here’s one that doesn’t.

Paul Barach, an anesthesiologist who accused his former employer, the University of New South Wales, of a massive cover-up — and in turn accused by his employer of being an academic grifter — has admitted making up the affair.

The Australian, which broke the story, says Barach — a U.S.-born physician — has apologized for making the claims. According to an earlier article in the paper:

Panel says BMJ was right to not retract two disputed statin papers

bmjA panel reviewing The BMJ‘s handling of two controversial statin papers said the journal didn’t err when it corrected, rather than retracted, the articles.

The articles — a research paper and a commentary — suggested that use of statins in people at low risk for cardiovascular disease could be doing far more harm than good. Both articles inaccurately cited a study that provided data important to their conclusions — an error pointed out vigorously by a British researcher, Rory Collins, who demanded that the journal pull the pieces.

In a letter to Godlee this spring, Collins wrote: Continue reading Panel says BMJ was right to not retract two disputed statin papers

Another Nature stem cell paper is retracted

nature 73014Another stem cell paper has been retracted from Nature, this one a highly cited 2008 study that had already been the subject of what the journal’s news section called a “furore” in 2010.

According to that 2010 news story:

The researchers behind the original work1, led by Thomas Skutella of the University of Tübingen, reported using cells from adult human testes to create pluripotent stem cells with similar properties to embryonic stem cells.

But a 2010 Brief Communication Arising called those findings into question. And now, the authors have retracted the paper. Here’s the notice for “Generation of pluripotent stem cells from adult human testis:” Continue reading Another Nature stem cell paper is retracted

Raymond Sawaya, director of MD Anderson’s brain tumor program, presents Jun Fu with the 2014 Caroline Ross Endowment Fellowship.

A former postdoc at MD Anderson Cancer Center faked the results of a mouse study of a Novartis compound designed to fight brain tumors, according to the Office of Research Integrity (ORI).

Jun Fu “admitted to knowingly and intentionally falsifying Figure 8a” in “Novel HSP90 Inhibitor NVP-HSP990 Targets Cell-Cycle Regulators to Ablate Olig2-Positive Glioma Tumor–Initiating Cells,” a paper published in Cancer Research on May 15, 2013:

Article about alcohol withdrawal withdrawn

A stumble in data preparation earned a retraction for a paper on delirium tremensalcohol_and_alcoholism, a life-threatening side effect of alcohol withdrawal that spans a wide range of symptoms, including hallucinations and seizures.

Here’s the notice from Alcohol and Alcoholism about “Biochemical Predictors of Delirium Tremens in Patients in Alcohol Withdrawal”:

Bitter rheumatology authorship dispute ends in retraction

rbrA 2012 expression of concern prompted by an authorship dispute has been upgraded to a retraction.

As we reported in 2012, Revista Brasiliera de Reumatologia (aka the Brazilian Journal of Rheumatology) issued an expression of concern about “Anticitrullinated peptide antibodies and rheumatoid factor in Sudanese patients with Leishmania donovani infection” after

a claim from one of the authors, questioning the authorship of the corresponding author, and informed that the article was under submission to another journal.

The journal sought the advice of the Committee on Publication Ethics (COPE), and continued its investigation. That investigation is apparently now complete, and this retraction notice is the result: Continue reading Bitter rheumatology authorship dispute ends in retraction
