Biological Trace Element Research has retracted a paper by a group of Egyptian authors for duplication.
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Article has been retracted due to duplicate publication.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: Continue reading Get the lead out: duplication leads to retraction of heavy metal paper
Last spring, we reported on the retraction in Clinical and Translational Allergy of a 2011 paper by researchers in Egypt and Finland after “severe problems in the data set” were uncovered. The notice cited an earlier study, from 2009, in Acta Paediatrica, that formed the basis for the subsequent trial.
At the time, the Acta Paediatrica paper still stood. No longer: Continue reading Allergy researchers lose second paper over “severe problems” with data
On Wednesday, the American Heart Association announced something that those of us who’d been reading the medical literature carefully had known for a while: Bad gums do not cause heart disease.
Periodontitis is linked to bad heart disease, you see, as studies have shown, and periodontists have sure been using this as an excuse to tell us to floss. But there’s never been a convincing study showing that one causes the other.
In fact, it’s not even clear how you’d do that study. “Let’s see, for a control group, we should have 100 people convince themselves they’re flossing for a year, but not actually floss….oh, what else can we get funding for?”
That “news” prompted an email from Retraction Watch friend Marc Abrahams, Continue reading A retracted periodontitis-heart disease paper that didn’t make it into the new AHA review
If you’re a rabbit and you haven’t figured out where to carry your cell phone, your front pocket is just fine.
That’s what you could reasonably infer from the retraction of a paper in the International Journal of Andrology purporting to show that mobile phones affected rabbits’ sperm counts. The notice, signed by the journal’s editor, Ewa Rajpert-De Meyts (we added links): Continue reading Rabbits needn’t worry about cell phones’ effects on their sperm count, say three retractions
It’s never a good sign when a paper has “severe” problems with its data. But when even the researchers are at a loss to explain how those problems made their way into the manuscript, well, that’s downright alarming.
Consider: The journal Clinical and Translational Allergy has retracted a 2011 article by researchers from Egypt and Finland, who have been studying the effects of vitamin C on childhood asthma. In a previous article, published in 2009 in Acta Paediatrica, members of the team reported that Continue reading Paper linking vitamin C and reduced asthma retracted after authors find “severe” problems with data
Research in Veterinary Science has retracted a 2010 paper by Egyptian scientists who published the same article the previous year in a different journal.
Here’s the retraction notice for the paper, “Comparative biochemical studies on steroidogenic compounds in chickens,” by Mohamed O.T. Badr and Mohamed A. Hashem, from Zagazig University and the Egyptian Ministry of Agriculture: Continue reading Which came first? Vet journal retracts previously published chicken paper
Both Retraction Watch bloggers are all too familiar with the artwork in dermatology journals. One of us, AM, used to write for Skin & Aging, while the other, IO, waited eagerly for issues of Cutis sent to his pediatrician father to show up on the coffee table. And IO recently broke the incredibly important story of “Mexican beer dermatitis.”
But we always trusted that the images we were looking at were real. A group of Egyptian dermatologists seems to have hit on a novel solution to the problem of uncooperative images: Continue reading Warts and all: Derm pub retracts plantar paper after author cries foul
