Retraction for image issues forces correction of herbal remedies editorial

Back in March, we wrote about the case of Chinese researchers who pulled their 2011 paper in the Journal of Molecular Medicine on ginseng’s potential as a heart remedy because a couple of their images were suspect (duplicated was the word they’d used).

Turns out the journal suffered some collateral damage. JMM also has corrected a “Clinical Implications” article by a group of Canadian researchers about the defunct ginseng paper.

The article, “Use of ginseng to reduce post-myocardial adverse myocardial remodeling: applying scientific principles to the use of herbal therapies,” appeared in the same issue as the original, but for some reason the correction notice appeared online only last week.

It states: Continue reading Retraction for image issues forces correction of herbal remedies editorial

Two Expressions of Concern in Blood for MD Anderson’s Aggarwal, who has threatened to sue Retraction Watch

Bharat Aggarwal, the MD Anderson researcher who has threatened to sue us while under investigation by his institution for alleged misconduct, now has two Expressions of Concern in addition to two corrections and two unexplained withdrawals.

Both of the papers were published in Blood. The Expression of Concern for “Gambogic acid, a novel ligand for transferrin receptor, potentiates TNF-induced apoptosis through modulation of the nuclear factor-κB signaling pathway,” reads: Continue reading Two Expressions of Concern in Blood for MD Anderson’s Aggarwal, who has threatened to sue Retraction Watch

Diabetes paper retracted for “misgrouping errors” that remain under investigation

A group of researchers at the University of Minnesota have retracted a paper in Diabetes for image problems, but exactly what happened is still under investigation.

Here’s the notice: Continue reading Diabetes paper retracted for “misgrouping errors” that remain under investigation

Streisand Effect meets tough editors as journal retracts already-corrected paper by Rui Curi

Rui Curi — the Brazilian scientist who threatened to sue the now-shuttered Science-Fraud.org site for criticizing his work — has rung up his second retraction, this one for a paper that he corrected earlier this year.

Here’s the Journal of Endocrinology notice, whose headers and language are a bit confusing, understandably, because it is retracting two things, a correction and the original paper: Continue reading Streisand Effect meets tough editors as journal retracts already-corrected paper by Rui Curi

Two cancer papers retracted because authors “are unable to guarantee the accuracy of some of the figures”

A team of researchers in Ireland has retracted two papers from Cancer Letters after concerns were apparently raised about some of the studies’ figures.

Denise Egan, of the Institute of Technology Tallaght in Dublin, and colleagues published “In vitro anti-tumour and cyto-selective effects of coumarin-3-carboxylic acid and three of its hydroxylated derivatives, along with their silver-based complexes, using human epithelial carcinoma cell lines” and “A study of the role of apoptotic cell death and cell cycle events mediating the mechanism of action of 6-hydroxycoumarin-3-carboxylatosilver in human malignant hepatic cells” in 2007.

The two notices say the same thing: Continue reading Two cancer papers retracted because authors “are unable to guarantee the accuracy of some of the figures”

Two more Eric Smart retractions appear

Eric Smart, the former University of Kentucky researcher found by the Office of Research Integrity to have faked images in ten papers, has two more retractions, both in the American Journal of Physiology — Cell Physiology.

Here’s one, for a paper cited four times, according to Thomson Scientific’s Web of Knowledge: Continue reading Two more Eric Smart retractions appear

University of Nebraska clears HIV researchers of misconduct

Last August, we reported on an Expression of Concern in the American Journal of Respiratory and Critical Care Medicine for a paper on HIV and lung injury. The notice said that the University of Nebraska, home to several of the paper’s authors, had begun an inquiry.
