Back in April, a group of French and Tunisian researchers published a paper in Biomaterials which came to the astonishing conclusion that buckyballs
(carbon tetrachloride) coated in olive oil could dramatically extend the lives of lab rodents. That news was picked up by Derek Lowe’s In the Pipeline blog, on which he expressed some bemusement about the work but ultimately praised it:
These are reasonable (but unproven) hypotheses, and I very much look forward to seeing this work followed up to see some more light shed on them. The whole life-extension result needs to be confirmed as well, and in other species. I congratulate the authors of this work, though, for giving me the most number of raised eyebrows I’ve had while reading a scientific paper in quite some time.
One of those eyebrows dropped a bit the following day, when Lowe reported that readers had pointed him to a clear case of image duplication in the article. At the time, Lowe concluded: Read the rest of this entry »
Last August, we brought you the news that the Indian Journal of Dermatology had banned a group of Tunisian researchers from publishing in the journal for five years, because they had plagiarized in a 2009 study.
Well, the journal’s editors found another case in which the authors have plagiarized, and now they’re banned from the journal for good. Here’s the notice, which describes both cases: Read the rest of this entry »
The group has one retraction, in the journal Obesity — whose splash page has the jaunty, if disconcerting, invite: “Welcome to Obesity!” — and at least two withdrawn papers. However, we have been alerted to at least one other case of apparent plagiarism involving an article in the Annals of Saudi Medicine that ought to receive careful scrutiny.

Thrombosis and Haemostasis has issued an “expression of concern” over a 2004 paper by Tunisian researchers:
Concerns have been raised by readers about the accuracy and validity of the data reported in the September 2004 article by Abdelkefi et al., entitled “Prevention of central venous line-related thrombosis by continuous infusion of low-dose unfractionated heparin, in patients with haemato-oncological disease. A randomized controlled trial” (Abdelkefi A et al.Thromb Haemost 2004; 92: 654–661).
In the trial, 108 patients with blood cancers reportedly received infusions of either saline or heparin, a blood thinner. Those given the active drug were far less likely to develop clots related to their catheters, according to the researchers, and no more likely to experience severe bleeding. In the report, the researchers write:
This is the first prospective, randomized study, which shows that low-dose of unfractionated heparin is safeand effective to prevent catheter-related thrombosis in patients with haemato-oncological disease.
The article has had an impact, having been cited 32 times, according to Thomson Scientific’s Web of Knowledge. At some point after publication, however, the results evidently began to look fishy. Again from the journal: Read the rest of this entry »
