Alirio Melendez, who was found guilty of scientific misconduct by the National University of Singapore and has had 13 papers retracted, says none of what he’s being accused of is true.
In a statement posted yesterday at ajmelendez.co.uk and this morning at Retraction Watch, Melendez acknowledges that fraud occurred in his laboratory, but “categorically” denies having taken part in it. Here’s the full statement: Read the rest of this entry »
Former National University of Singapore and University of Liverpool scientist Alirio Melendez has two more of the 20-something retractions suggested by the investigations into his work. Both appear in the Journal of Biological Chemistry.
Here’s the notice for “Refining siRNA in vivo transfection: Silencing SPHK1 reveals its key role in C5a-induced inflammation in vivo,” by Alirio Melendez and colleagues in The International Journal of Biochemistry & Cell Biology: Read the rest of this entry »
And then there were eight: Three more retractions for Alirio Melendez, all in the Journal of Immunology
Alirio 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: Read the rest of this entry »
Alirio Melendez, a former National University of Singapore immunologist whose story we’ve been following here since a retraction in September of last year, committed misconduct on an “unprecedented” scale, according to the university, involving more than 20 papers.
Nature’s Richard van Noorden has the scoop:
After a 19-month investigation, the National University of Singapore (NUS) today says that it has determined that one of its former scientists, the immunologist Alirio Melendez, has committed “serious scientific misconduct”. The university found fabrication, falsification or plagiarism associated with 21 papers, and no evidence indicating that other co-authors were involved in the misconduct, it says.
A new retraction — his fifth — in the Journal of Immunology for Alirio Melendez, formerly of the National University of Singapore, the University of Glasgow, and the University of Liverpool, sheds some light on the results of an investigation by one of the universities.
Last month, a Glasgow spokesperson told Nature that the university’s investigation had been completed in October 2011, but that it did not comment on individual cases. A spokesperson, according to the Times Higher Education:
…would say only that there was “no evidence that our current staff contributed, falsified or duplicated data to any publications co-authored with (Professor) Melendez”. He also confirmed that relevant journals would be contacted where retractions or corrections were deemed necessary.
Retraction number four appears in PNAS for work of Alirio Melendez, who has resigned post at U Liverpool
Alirio Melendez, who has had three of his papers retracted amidst suspicions about 70, has had another one retracted, this one in the Proceedings of the National Academy of Sciences (PNAS). And he has also resigned from his post at the University of Liverpool, we have just learned.
