“Highly unethical practices” force four retractions for nanotech researcher
All four notices say the same thing:
This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).
This article has been retracted at the request of the Editor-in-Chief.
Due to highly unethical practices, which include serial self plagiarism, data manipulation and falsification of results found across multiple papers in Acta Biomaterialia. One of the conditions of submission of a paper for publication is that authors declare explicitly that their work is original and has not appeared in a publication elsewhere. Re-use of any data should be appropriately cited. As such this article represents a severe abuse of the scientific publishing system. The scientific community takes a very strong view on this matter and apologies are offered to readers of the journal that this was not detected during the submission process.
The four papers are:
- Epithelial cell adhesion molecule targeted nutlin-3a loaded immunonanoparticles for cancer therapy (cited four times, according to Thomson Scientific’s Web of Knowledge)
- Antiglioma activity of curcumin-loaded lipid nanoparticles and its enhanced bioavailability in brain tissue for effective glioblastoma therapy (cited twice)
- Transferrin-conjugated curcumin-loaded superparamagnetic iron oxide nanoparticles induce augmented cellular uptake and apoptosis in K562 cells (cited three times)
- Enhanced antiproliferative activity of carboplatin loaded chitosan-alginate nanoparticles in retinoblastoma cell line (cited 15 times)
Here’s Sahoo’s bio:
The primary aim of our research endeavour is in the field of nanomedicine which is the buzz word used nowadays in every sphere of life. Our group is mostly engaged in development of drug delivery system which yield advances in early detection, diagnostics, prognostics of cancer. Our research expertise has resulted in development of different nanocarriers which have shown promising results in a wide spectrum of cancer. Our research activities are not only limited to drug delivery but has also ventured into areas of diagnostics with our magnetic nanoparticles which have resulted in development of realistic practical applicants as the next generation drug delivery system and contrast agents. Our recent formulation i.e. curcumin sponge has been implicated for wound healing purpose which can be a boon for diabetic patients. Moreover the fascinating and unexplored area of polymer bioconjugate chemistry has also been another novel area of research our group has undertaken recently where our pegylated formulations of anticancer drugs and therapeutic peptides have resulted in increasing their in vivo longevity contributing to their enhanced potency. Our futuristic objective remains overcoming the multi drug resistance (MDR) effect as well as crossing the blood brain barrier using our nanocarriers thereby overcoming all the shortcoming of conventional therapy.
