AIDS denialism paper retracted after Jeffrey Beall draws attention to it

scirpA paper arguing that HIV does not cause AIDS has been retracted a few weeks after Jeffrey Beall, who tracks predatory publishers, called attention to it on his blog.

Here’s what Beall wrote about the paper on December 16:

The article is entitled “Basic Principles Underlying Human Physiology” [1], and you don’t have to be a scientist to know that it’s junk, for it is a manifestation of AIDS denialism. The conclusion’s first paragraph says,

HIV is not etiologically involved in AIDS. It is just a common retrovirus found in AIDS conjuncturally. There is only AIDS that may not be strictly associated neither to a primary immune deficiency nor to an acquired immune deficiency. Actually, heart failure represents the causal factor of AIDS and many other “primary” immune deficiencies (p. 1821).

Now, in that article’s place, this retraction, dated December 19, appears: Continue reading AIDS denialism paper retracted after Jeffrey Beall draws attention to it

Fake peer review fells two more papers

medicineThe number of papers retracted for fake peer reviews — well in excess of 100, by our count — continues to grow.

The latest to join the list are “Rebamipide plus proton pump inhibitor versus proton pump inhibitor alone in treatment of endoscopic submucosal dissection-induced gastric ulcer: a meta-analysis of randomized controlled trials” and “Association study of TGFBR2 and miR-518 gene polymorphisms with age at natural menopause, premature ovarian failure and early menopause among Chinese Han women,” both published in 2014 in Medicine.

Here’s how both notices, signed by senior publisher Duncan A. MacRae, read: Continue reading Fake peer review fells two more papers

Stem cell study retraction produces useless notice

int j stem cellsWe don’t have much to go on here, for a retraction from the International Journal of Stem Cells. 

Here’s what we do know: Dental researchers at several universities in Egypt, including Cairo University, Future University, and Misr University published a paper together. According to the article, they gave dogs oral ulcers and then injected the ulcers with either fat-derived stem cells, bone marrow stem cells, or saline. The researchers conclude that the fat stem cells, also known as adipose derived stem cells, helped the dogs heal.

Unfortunately, we have no idea what went wrong, because the retraction notice is useless. Here in its entirety is the notice for “Adipose Stem Cells as Alternatives for Bone Marrow Mesenchymal Stem Cells in Oral Ulcer Healing”: Continue reading Stem cell study retraction produces useless notice

Nature Cell Biology insulin paper retracted over antibody problems

nature cell biologyA Nature Cell Biology article on insulin regulation has been retracted after scientists noted that the antibodies used in their research were not as specific as they had previously believed.

The notice is clear on the problems with the science, which together “call into question the main conclusions of the paper.” Three of the paper’s five authors were employed at Novartis at the time of publication.

Here’s the notice for “Wolfram syndrome 1 and adenylyl cyclase 8 interact at the plasma membrane to regulate insulin production and secretion”: Continue reading Nature Cell Biology insulin paper retracted over antibody problems

“Incorrect data” kills apoptosis paper

Screen Shot 2014-12-19 at 5.52.16 PMFrontiers in Pharmacology has retracted a paper on baicalin, an antioxidant sold in health food stores, because it had both “incorrect data and invalid statistical analyses.”

A comment on PubPeer notes that one of the figures (see image to the right) contains two similar-looking flow cytometry images labeled with different values, which could be what the retraction is hinting at.

Here’s the notice for “Baicalin induced dendritic cell apoptosis in vitro”: Continue reading “Incorrect data” kills apoptosis paper

Paper recommending calorie limits on Happy Meals retracted

A paper estimating the effects of limiting fast food meals with toys to under 550 calories has been retracted after concerns arose regarding the scientists’ use of an outdated model for estimating weight changes in kids.

The paper estimated that kids who eat fast food twice a week would avoid gaining two pounds a year if calorie limits are imposed on meals with toys. However, everyone we spoke to, and the notice, indicated that their estimate was inaccurate.

Here’s the notice for “Modeling Potential Effects of Reduced Calories in Kids’ Meals with Toy Giveaways”:

Paper that formed basis of study retracted earlier this year retracted itself, from Science

science dec 2014Back in May, we reported on a retraction from Molecular Cell that referred to a 2012 study the same group had published in Science. (A few weeks later, the lab head told us just how painful the process was.)

Now, the Science paper has been retracted. Here’s the notice: Continue reading Paper that formed basis of study retracted earlier this year retracted itself, from Science

Researchers retract paper for which first author won an award — but won’t sign notice

Most of the authors of two Molecular Cell papers have retracted them after becoming aware of inappropriate image manipulation by the first author of both — who refused to sign the notices.

One of the papers, “Role of the SEL1L:LC3-I Complex as an ERAD Tuning Receptor in the Mammalian ER,” earned first author Riccardo Bernasconi, who successfully defended his PhD in 2010, the STSBC-Roche Diagnostics award in 2012. Here’s the notice for that paper: Continue reading Researchers retract paper for which first author won an award — but won’t sign notice

That new beetle? Actually, it’s really an old beetle

A team of entomologists in India had to put their new species celebration on hold last year, when they found out their discovery had already been discovered.

The Journal of Insect Science paper, initially published in December 2012, was retracted in October 2013, after several entomologists confirmed that the beetle was actually a previously identified species called Acanthophorus serraticornis. (The notice has a November 2014 date, but we understand that’s because the journal switched servers.)

Here’s the notice for “A new record of longicorn beetle, Acanthophorus rugiceps, from India as a root borer on physic nut, Jatropha curcas, with a description of life stages, biology, and seasonal dynamics”: Continue reading That new beetle? Actually, it’s really an old beetle

Stem cell researcher retracts neuron paper for “image aberrations”

embo journalJens Christian Schwamborn, a stem cell researcher at the University of Luxembourg, is retracting a 2007 paper on how to grow brain cells.

The paper, “Ubiquitination of the GTPase Rap1B by the ubiquitin ligase Smurf2 is required for the establishment of neuronal polarity,” was published while Schwamborn was at Westfälische Wilhelms‐Universität Münster in Germany. An anonymous critic had sent questions about the study to Germany’s DFG in the middle of last year, and later to Paul Brookes, who posted them on PubMed Commons.

Those criticisms match the problems listed in the detailed notice: Continue reading Stem cell researcher retracts neuron paper for “image aberrations”
