RESUMO

BACKGROUND: The practice of clinical research is strictly regulated by law. During submission and review processes, compliance of such research with the laws enforced in the country where it was conducted is not always correctly filled in by the authors or verified by the editors. Here, we report a case of a single institution for which one may find hundreds of publications with seemingly relevant ethical concerns, along with 10 months of follow-up through contacts with the editors of these articles. We thus argue for a stricter control of ethical authorization by scientific editors and we call on publishers to cooperate to this end. METHODS: We present an investigation of the ethics and legal aspects of 456 studies published by the IHU-MI (Institut Hospitalo-Universitaire Méditerranée Infection) in Marseille, France. RESULTS: We identified a wide range of issues with the stated research authorization and ethics of the published studies with respect to the Institutional Review Board and the approval presented. Among the studies investigated, 248 were conducted with the same ethics approval number, even though the subjects, samples, and countries of investigation were different. Thirty-nine (39) did not even contain a reference to the ethics approval number while they present research on human beings. We thus contacted the journals that published these articles and provide their responses to our concerns. It should be noted that, since our investigation and reporting to journals, PLOS has issued expressions of concerns for several publications we analyze here. CONCLUSION: This case presents an investigation of the veracity of ethical approval, and more than 10 months of follow-up by independent researchers. We call for stricter control and cooperation in handling of these cases, including editorial requirement to upload ethical approval documents, guidelines from COPE to address such ethical concerns, and transparent editorial policies and timelines to answer such concerns. All supplementary materials are available.

RESUMO

Recently, an article by Seneff et al. entitled "Innate immunosuppression by SARS-CoV-2 mRNA vaccinations: The role of G-quadruplexes, exosomes, and MicroRNAs" was published in Food and Chemical Toxicology (FCT). Here, we describe why this article, which contains unsubstantiated claims and misunderstandings such as "billions of lives are potentially at risk" with COVID-19 mRNA vaccines, is problematic and should be retracted. We report here our request to the editor of FCT to have our rebuttal published, unfortunately rejected after three rounds of reviewing. Fighting the spread of false information requires enormous effort while receiving little or no credit for this necessary work, which often even ends up being threatened. This need for more scientific integrity is at the heart of our advocacy, and we call for large support, especially from editors and publishers, to fight more effectively against deadly disinformation.

RESUMO

Substance P (SP) interacts with the neurokinin-1 (NK-1) G-protein-coupled receptor, which has been cloned in several species. In the present study, the domains of the NK-1 receptor involved in the binding of SP and SP-(7-11) C-terminal fragment have been analyzed using two peptide analogs containing the photoreactive amino acid para-benzoylphenylalanine ((p-Bz)Phe) in position 8 of their sequence. This study was carried out with [BAPA-Lys(6),(p-Bz)Phe(8),Pro(9),Met(O(2))(11)]SP-(7-11) and [BAPA(0),(p-Bz)Phe(8)]SP on both rat and human NK-1 receptors expressed in CHO cells. Combined trypsin and endo-GluC enzymatic complete digestions and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry analysis led to the identification of the same domain of covalent interaction, (173)TMPSR(177), for the two photoactivatable peptides. Further digestion of this fragment with carboxypeptidase Y led to the identification of (173)TMP(175) in the second extracellular loop (E2) of the NK-1 receptor as the site of covalent attachment. Models of the conformation of this E2 loop in the human NK-1 receptor were generated using two different strategies, one based on homology with bovine rhodopsin and the other based on the solution conformation preferences of a synthetic peptide corresponding to the E2 loop.
