After a series of documentaries prompted his former employer, Karolinska Institutet (KI), to reopen a misconduct investigation against him, KI has today released one verdict regarding a 2014 Nature Communications paper: guilty.
KI said it is contacting the journal to request a retraction of the paper, which has already been flagged with an expression of concern.
Here’s more from a release from the institution: Read the rest of this entry »
Nature Communications has issued an expression of concern for a 2014 paper by beleaguered surgeon Paolo Macchiarini, citing concerns over whether the paper accurately reports the experiments that were carried out.
According to the notice, Macchiarini, a former rising star in the field of transplant medicine, agrees with the expression of concern. Three of his 22 co-authors have objected.
“Experimental orthotopic transplantation of a tissue-engineered oesophagus in rats” describes transplanting an esophagus into rats that was seeded with their own stem cells, and notes that all animals survived the study period (14 days), and gained more weight than rats given a placebo operation. It’s a topic Macchiarini has made famous, as the first surgeon to perform a similar procedure with a human tracheal transplant. But he’s faced charges of misconduct in the last few years, resulting in his dismissal from Karolinska Institutet (KI).
Two weeks after Nature Communications published a paper on asymmetric cell division in July, it posted a retraction notice saying the paper was submitted “without the knowledge or consent” of all but the corresponding author.
The following day the journal “amended” the retraction note to include the initials of the corresponding author, Aicha Metchat, then based at European Molecular Biology Laboratory in Heidelberg, Germany.
The final notice for “An actin-dependent spindle position checkpoint ensures the asymmetric division in mouse oocytes” reads:
It’s not unusual to hear authors bemoan the fact that a new paper doesn’t cite their work that set the stage for a scientific advance. “The journal limited me to [a seemingly abitrary number of] references,” authors sometimes shrug, with or without apology. This week, however, we found a case of that which seems to have been resolved to everyone’s satisfaction.
The authors of a September 2013 article in Nature Communications have issued a correction for the piece, which failed to cite the source of a key step in their experiment.
The article, “Val66Met polymorphism of BDNF alters prodomain structure to induce neuronal growth cone retraction,” came from the lab of William “Clay” Bracken, a biochemist at Weill Cornell Medical College. According to the abstract: Read the rest of this entry »
