The reason: Image manipulation — which the authors say didn’t materially affect the conclusions of the paper.
The article, “FAK mediates the activation of cardiac fibroblasts induced by mechanical stress through regulation of the mTOR complex,” came from a group led by Ana Paula Dalla Costa, from the State University of Campinas.
The last author is baffled as to why the journal couldn’t have made that call before they published the abstract.
A pair of researchers who have been calling for the retraction of two papers by cardiology researcher Don Poldermans say the New England Journal of Medicine is
“not justified” “disappointing” in its refusal to pull the articles.
A little background: Poldermans resigned from Erasmus University in 2011 after having been accused of misconduct. Last week, we reported that the European Heart Journal had issued an expression of concern for a 2001 article on which he was first author.
The New England Journal of Medicine added editor’s notes to two of Poldermans’ articles. But as Larry Husten at Forbes reports, the journal has no intention of retracting the papers: Read the rest of this entry »
A cardiology paper from China has been retracted because “permission to report these discussions was not sought nor obtained,” though it’s unclear what “the discussions” refers to. The person to whom the discussions are attributed to in the retraction, Ji Bingyang, is not an author on the paper, and none of his papers are cited in the retracted article.
The paper, “The Effect of Soluble RAGE on Inhibition of Angiotensin II-Mediated Atherosclerosis in Apolipoprotein E Deficient Mice,” came from a group of researchers in South Korea.
It purported to show that: Read the rest of this entry »
The European Heart Journal has issued an expression of concern for a
2014 2001 paper by Don Poldermans, the Dutch heart researcher who stepped down from his post at Erasmus University after being accused of misconduct.
The article, “Bisoprolol reduces cardiac death and myocardial infarction in high-risk patients as long as 2 years after successful major vascular surgery,” appeared in July and reported data from the DECREASE trial. Poldermans, who left Erasmus in 2011, has acknowledged failing to receive informed consent from some patients in one phase of the DECREASE study but denied having fabricated results.
Sometimes plagiarism can be tricky to catch when an article has to be translated before publication.
That seems to be the case for two papers out of a hospital in Canakkale, Turkey, that discussed results of two different kinds of heart surgery.
Here’s the retraction notice for “The effects of 21 and 23 milimeter aortic valve prosthesis on hemodynamic performance and functional capacity in young adults,” in the Pakistan Journal of Medical Sciences: Read the rest of this entry »
The articles — a research paper and a commentary – suggested that use of statins in people at low risk for cardiovascular disease could be doing far more harm than good. Both articles inaccurately cited a study that provided data important to their conclusions — an error pointed out vigorously by a British researcher, Rory Collins, who demanded that the journal pull the pieces.
In a letter to Godlee this spring, Collins wrote: Read the rest of this entry »
Researchers at Qingdao University have fully retracted a paper originally published in Molecular Medicine Reports with a clear, detailed outline of what went wrong and how they discovered the error.
Here’s the notice for “Generation of induced pluripotent stem cells using skin fibroblasts from patients with myocardial infarction under feeder-free conditions:”
