On November 11, St. Louis’s KTVI reported that krokodil, a nasty opioid concoction with roots in Russia, had arrived in their town. They based that report on a case study published in the American Journal of Medicine, “Krokodil’—A Designer Drug From Across the Atlantic, with Serious Consequences,” and interviewed two of the paper’s authors, Dany Thekkemuriyil and Unnikrishnan Pillai.
The case study involved a 30-year-old man the Thekkemuriyil and Pillai said they had seen at St. Mary’s Health Center in Richmond Heights, Missouri. As the St. Louis Post-Dispatch reported a few days later: Read the rest of this entry »
The paper — by Gilles Seralini and colleagues — was published in Food and Chemical Toxicology last year. There have been calls for retraction since then, along with other criticism and a lengthy exchange of letters in the journal. Meanwhile, the paper has been cited 28 times, according to Thomson Scientific’s Web of Knowledge, and the French National Assembly (their lower house of Parliament) held a long hearing on the paper last year, with Seralini and other scientists testifying.
The article, “Bacterial lipopolysaccharide-induced oxidative stress in adult rat Sertoli cells in vitro,” was written by Hamdy A.A. Aly, Hany A. El-Shemy and David A. Lightfoot, a professor of biotechnology and genomics at Southern Illinois University in Carbondale. El-Shemy, now of Cairo University, was a visiting scholar at SICU a few years ago, and he and Lightfoot have published together several times. Read the rest of this entry »
Sreenivasan Sasidharan, a researcher at the Institute for Research in Molecular Medicine (INFORMM), part of the Universiti Sains Malaysia, used a bottle labeled lantadene A, a liver-destroying chemical from the leaves of the Lantana camara plant that some livestock eat.
Sasidharan found that contrary to expectations, “lantadene A” protected livers against damage from acetaminophen — aka Tylenol.
The paper, “The Effect of Lead Acetate Toxicity on Experimental Male Albino Rat,” came from investigators in the department of Economic Entomology and Pesticides at Cairo University and appeared in December 2011. As the notice states:
Article has been retracted due to duplicate publication.
Here’s the abstract: Read the rest of this entry »
Left and right apparently agree that “GMO” studies should be retracted (but they’re talking about different papers)
We couldn’t help noticing that the past few weeks have seen calls to retract two papers on food, from different sides of the political spectrum. One paper actually looked at the effects of genetically modified organisms (GMOs), while the GMO link in the other paper seems mostly to be in activists’ minds. Consider:
On the right, we have Henry I. Miller writing on Forbes.com about a study of rats fed genetically modified maize: “The honorable course of action for the journal would be to retract the paper immediately“: Read the rest of this entry »
We’ve seen this movie before: Researchers present a study at a scientific meeting, then learn to their surprise (and, sometimes, chagrin) that a journal has published the data in a supplement or other edition.
The work was titled “Molecular mechanisms involved in resistance of CLL cells towards ABT-737, a specific BCL-2 inhibitor.” Gerald Cohen, of the University of Leicester, who led the study, told us: Read the rest of this entry »
