Mislabeled chemical bottle leads to retraction of liver protection paper

molecules-logoA labeled chemical bottle may contain a genie and not the expected reagent, according to a cautionary retraction that could be a warning for all bench researchers.

Sreenivasan Sasidharan, a researcher at the Institute for Research in Molecular Medicine (INFORMM), part of the Universiti Sains Malaysia, used a bottle labeled lantadene A, a liver-destroying chemical from the leaves of the Lantana camara plant that some livestock eat.

Sasidharan found that contrary to expectations, “lantadene A” protected livers against damage from acetaminophen — aka Tylenol.

But Manu Sharma, assistant pharmacy professor at Jaypee University of Information Technology in India, suspected something was technically amiss: Continue reading Mislabeled chemical bottle leads to retraction of liver protection paper

Without “confidence in the conclusions,” group retracts prostate cancer paper

redjournalBack 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:

Today, the university issued a statement on the case, clearing the researchers of misconduct: Continue reading University of Nebraska clears HIV researchers of misconduct

MD Anderson’s Bharat Aggarwal inquiry still ongoing; center uninvolved in legal threats

Bharat Aggarwal

When we learned earlier this week that Bharat Aggarwal, the MD Anderson researcher under investigation there for possible misconduct, had directed his attorneys to send us a pull-all-your-posts-about-our-client-or-we’ll-sue-you letter, we wondered if he’d included the Houston institution in that decision.

Turns out he’d been acting on his own. Continue reading MD Anderson’s Bharat Aggarwal inquiry still ongoing; center uninvolved in legal threats

Spud dud, as agricultural industry potato paper gets pulled a decade after publication

plantphyscoverPlant Physiology, the official journal of the American Society of Plant Biologists, has retracted a 2004 article by a team of ag industry researchers, including a former husband-wife duo, for what could be misconduct by the husband.

The retraction notice is vague enough, however, that we’re not entirely sure what went wrong, and no one wants to help us confirm — or even attempt to disprove — our inferences. Continue reading Spud dud, as agricultural industry potato paper gets pulled a decade after publication
