Title: Industrial antifoam agents impair ethanol fermentation and induce stress responses in yeast cells

What Caught Our Attention: When authors decide they want to make their articles freely available after they’ve already been published, how should publishers indicate the change, if at all? Recently, Ross Mounce (@rmounce) thought it was odd a Springer journal issued a formal correction notice when the authors wanted to make their paper freely available, and we can’t say we disagree.  As he posted on Twitter:

Brazil research foundation sues scientist over $103k scholarship

with 3 comments

The São Paulo Research Foundation (FAPESP), a state-level agency in Brazil that funds scientific research, is suing Paty Karoll Picardi, a protégé of Brazilian diabetes researcher Mario Saad.

According to a São Paulo Court of Justice website, the reason stated is for “recebimento of bolsa de estudos,“ which translates to “receipt of scholarship.” FAPESP is suing for 334,116 Brazilian Reals ($102,927).

Now, Picardi is counter-suing, according to a case document released Nov. 17 — although we’re not sure for what, and why.  Read the rest of this entry »

Reader complaints prompt retraction of meta-analysis of heart-failure drug

without comments

A cardiology journal has retracted a 2016 meta-analysis after the editors had an, ahem, change of heart about the rigor of the study.

The article, “Ivabradine as adjuvant treatment for chronic heart failure,” was published in the International Journal of Cardiology, an Elsevier title.

The authors, a group at the Federal University of São Paulo, Brazil, concluded that: Read the rest of this entry »

Diabetes researcher who sued to prevent retractions now has 13

with 5 comments

A diabetes researcher who sued a publisher to protect several papers from being retracted recently received his 13th, in a prestigious gastroenterology journal.

Mario Saad, based at the University of Campinas in São Paulo, Brazil, has had a string of retractions over the past few years, including four in Diabetes after he lost a legal battle with the American Diabetes Association.

The latest retraction appears in Gastroenterology, citing possible image duplication. Saad is second-to-last author on the 2012 paper.

According to the retraction notice, the journal investigated data in several figures, and believes some were duplicated. The authors explained that the duplications resulted from inadvertently using wrong blots; still, the editors chose to retract the paper after determining they no longer had confidence in its conclusions.  

Here’s the retraction notice for “Obesity-Induced Increase in Tumor Necrosis Factor-α Leads to Development of Colon Cancer in Mice:” Read the rest of this entry »

Researcher who sued to prevent retractions now has 12

with one comment

A diabetes researcher who once sued a publisher to prevent several retractions has just issued his 12th.

The latest retraction, like several others for Mario Saad, appears in the journal Diabetes. Although in the past Saad expended considerable effort to protect four other Diabetes papers from this same fate, the latest retraction was initiated by the authors, citing several duplicated images. The American Diabetes Association had flagged the 2009 paper with an expression of concern earlier this year.

In 2015, Saad brought a lawsuit against the ADA, claiming that it “wrongfully published” four expressions of concerns in its flagship journal Diabetes, in an attempt to prevent the papers from being retracted. He lost, and the papers were retracted in 2016.

The lawsuit also did nothing to deter the ADA from flagging other potentially problematic papers with expressions of concerns, including the latest 2009 Diabetes paper, on which Saad is last and corresponding author.  Read the rest of this entry »

Researcher sued to stop retractions; he just earned two more and is now up to 11

without comments

The notices keep coming for diabetes researcher Mario Saad.

Diabetes has just retracted two more of his papers, both of which had been flagged by expressions of concern, citing problems with duplications. What’s more, the journal added another expression of concern to a 2009 paper on which Saad — based at the University of Campinas in São Paulo, Brazil — is listed as last author, again over concerns of duplication.

This isn’t Saad’s first run-in with the journal: In 2015, the researcher sued the publisher, the American Diabetes Association, after it issued expressions of concern for four of his papers. Later that year, a judge dismissed Saad’s defamation suit. The journal eventually retracted the papers.

The latest articles flagged by Diabetes appear to be part of an intricate publishing web, as the journal suggests all papers have used features of previous papers, and also include elements that have been republished by subsequent articles.

Here’s the first retraction notice, for “A Central Role for Neuronal AMP-Activated Protein Kinase (AMPK) and Mammalian Target of Rapamycin (mTOR) in High-Protein Diet–Induced Weight Loss:”

Researcher logs three retractions for image duplications — two of which with familiar co-authors

with one comment

A researcher in Brazil is taking responsibility for accidentally mixing up images in three papers in the Journal of Biological Chemistry. 

The corresponding author on the three papers told us the mistake happened because the studies were conducted simultaneously, and relied on one computer.

There’s a side note to these retractions: The co-author list on two papers includes names that should be fairly well-known to our readers — Mario Saad, the researcher who unsuccessfully sued the American Diabetes Association to stop retractions of his papers, and Rui Curi, a researcher whose legal threats assisted in the shutdown of Science-Fraud.org. This makes Saad’s ninth retraction.

According to the retraction notices, Lício Velloso  — who, like his co-authors, is based at the University of Campinas in São Paulo, Brazil — assembled all the figures. He told Retraction Watch that the authors initially wanted to correct the papers, adding: Read the rest of this entry »

New funding for researcher who sued to stop retractions (and now has 8)

Mario Saad

Mario Saad

A diabetes researcher with eight retractions — despite his attempts to block some in court — has received a new batch of research funding.

According to a release from public funding agency Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP), Mario Saad is among 33 researchers who will receive funding from partnerships between federal and state agencies, including FAPESP.

It’s unclear how much Saad’s project will individually receive, but the total for all projects exceeds 640 million Brazilian Real, equivalent to $185 million USD.

Saad’s name should be familiar to our readers.

Official notice published for chem paper slated for retraction in 2011

with one comment

process-safetyAfter five years, Elsevier has finally issued a notice of retraction for a paper it announced it was pulling for fraud in 2011.

All of the papers were produced by a research group in Brazil; all were retracted after the publisher conducted an investigation, concluding that the NMR results had been manipulated. At the time, the last author on the latest retraction, Claudio Airoldi, defended the work. Since then, however, Airoldi has logged two more retractions, bringing his total to 13.

Here’s the full text of the retraction notice, from Process Safety and Environmental Protection: Read the rest of this entry »

Authors didn’t generate key brain images, probe finds

with 3 comments

Frontiers in Human NeuroscienceA neuroscience journal has issued a retraction after discovering some of the paper’s integral images didn’t originate from the authors’ labs.

The retraction notice  — for a study about a condition once known as “water on the brain” — cites an investigation by the journal’s publisher, Frontiers, which determined that the figures were not “duly attributed.” The authors say they agree with the retraction.  

Here’s the retraction notice for “Revisiting hydrocephalus as a model to study brain resilience,” published by Frontiers in Human Neuroscience: Read the rest of this entry »
