如果你就好那口儿，无所谓，接着喝。
如果你是因为信了所谓红酒对心血管有好处的说法才饮用的，恭喜你了，丑闻来了！
University Suspects Fraud by a Researcher Who Studied Red Wine
A charge of widespread scientific fraud, involving 26 articles published in
11 journals, was leveled by the University of Connecticut today against
Dipak K. Das, one of its researchers, whose work reported health benefits in
red wine.
Many of the articles reported positive effects from resveratrol, an
ingredient of red wine thought to promote longevity in laboratory animals.
The charges, if verified, seem unlikely to affect the field of resveratrol
research itself, because Dr. Das’s work was peripheral to its central
principles, several of which are in contention. “Today I had to look up who
he is. His papers are mostly in specialty journals,” said David Sinclair,
a leading resveratrol expert at the Harvard Medical School.
The significance of the case seems more to reflect on the general system of
apportioning research money. Researchers complain that federal grants are
increasingly hard to get, even for high-quality research, yet money seemed
to have flowed freely to Dr. Das, who was generating research of low
visibility and apparently low quality. The University of Connecticut said
Wednesday that it was returning two new grants to Dr. Das, worth a total of
$890,000, to the federal government.
The agency that granted the funds was the National Heart, Lung and Blood
Institute. Renate Myles, a spokeswoman, said in response that scientific
misconduct “can go undetected for a length of time even under the most
rigorous systems of research oversight and review.”
The investigation of Dr. Das’s work began in January 2009, two weeks after
the university received an anonymous allegation about research
irregularities in his laboratory. A special review board headed by Dr. Kent
Morest of the University of Connecticut has now produced a 60,000-page
report, which has been forwarded to the Office of Research Integrity, a
federal agency that investigates fraud by researchers who receive government
grants.
According to a 60-page summary of the report, Dr. Das’s published research
articles were found to contain 145 instances of fabrication and
falsification of data. Many involved cutting and pasting photographic images
from a type of research record known as a western blot. Because western
blots have often been subject to manipulations in the past, many journals
require that the images not be altered in any way without an explicit
description of the procedure.
Dr. Das did not answer his phone at the university or respond to e-mail.
The university has sent a copy of its report to the editors of the 11
journals that published the suspect articles.
Adam Marcus, who edits the blog Retraction Watch, an inventory of the
growing number of discredited scientific reports, said he would be
monitoring the journals to see whether retractions were issued, a step that
some editors are reluctant to take.
Dr. Das was a prolific publisher of research. His name appears on 588
articles listed in Google Scholar, though some may be by other researchers
with the same name and initials. Most of the articles concern the effect of
drugs on the heart, including 117 articles on resveratrol. | s*****o
