Out of the running: Dodgy blots prompt retraction of paper on marathoning and cell death

bmc physiologyA group of exercise researchers at the University of Rome Tor Vergata has lost their May 2010 paper in BMC Physiology on the effects of marathon running on blood cells, because of figure irregularities.

The article, “The effect of marathon on mRNA expression of anti-apoptotic and pro-apoptotic proteins and sirtuins family in male recreational long-distance runners,” purported to find that marathoning arrested apoptosis, or programmed cell death. It has been cited 13 times, according to Thomson Scientific’s Web of Knowledge.

University of Luxembourg investigation leads to neuroscience retraction

gliaA study published in Glia is being retracted following a university investigation that found “incorrect and, therefore, misleading” results in a number of figures.

Here’s the notice for  “Jagged1 regulates the activation of astrocytes via modulation of NFκB and JAK/STAT/SOCS pathways” by Eleonora Morga, Laila Mouad-Amazzal, Paul Felten, Tony Heurtaux, Mike Moro, Alessandro Michelucci, Sebastien Gabel, Luc Grandbarbe, and Paul Heuschling: Continue reading University of Luxembourg investigation leads to neuroscience retraction

A former postdoc at the National Institutes of Health (NIH) committed misconduct in a study of hepatitis by falsely claiming that data from a single trial subject were actually from more than a dozen different people, the Office of Research Integrity (ORI) has found.

The investigation was prompted by allegations made by readers of the paper. Baoyan Xu made what the ORI called “a limited admission” that “some better looking strips were repeatedly used as representatives for several times [sic].”

According to a report of the ORI’s findings to be published in the Federal Register tomorrow, the paper, “Hybrid DNA virus in Chinese patients with seronegative hepatitis discovered by deep sequencing, published earlier this year in the Proceedings of the National Academy of Sciences (PNAS): Continue reading Former NIH scientist falsified images in hepatitis study: ORI

“Not suitable in this context” means retraction in pharmacology journal

pbbPharmacology Biochemistry and Behavior had a curious retraction notice in September that we’re just now getting around to, but we think you’ll find it to have been worth the wait.

The article, “Interaction of Somatostatin Receptor-2 and Neuropeptide Y Receptor-1 in mice dorsal root ganglion neurons on the Pinch-Nerve injury model,” came from a group in Harbin, China, and Frieburg, Germany, and was published in April 2013.

Two researchers in Denmark are guilty of scientific dishonesty, the Danish Committees on Scientific Dishonesty (DCSD, Danish acronym UVVU) has concluded.

In July, the DCSD said in a draft report that Bente Klarlund Pedersen had acted in a “scientifically dishonest” and “grossly negligent” manner. She — and many of her defenders — responded by saying that while she had made mistakes, she had not committed misconduct. Here’s a key quote from a letter her attorney wrote to the committee: Continue reading Danish commitee finds Klarlund Pedersen, Penkowa guilty of scientific dishonesty
