HARTFORD, Conn. — A U.S. university says a researcher known for his work on red wine's benefits to cardiovascular health falsified his data in more than 100 instances.

Nearly a dozen scientific journals are being warned of the potential problems after publishing the University of Connecticut professor's studies.

University officials say dismissal proceedings have started against Dipak Das, director of the UConn Health Center's Cardiovascular Research Center.

UConn says it started investigating Das' work after receiving an anonymous complaint of potential irregularities in his research, and that it found 145 instances of fabricated, falsified and manipulated data.

Das has gained attention for research into an ingredient in red wine that's shown potential for promoting health, though the university did not say whether the falsifications occurred in research on that topic.

Das could not immediately be reached for comment.
