Hartford - A University of Connecticut researcher known for his work on red wine's benefits to cardiovascular health falsified his data in more than 100 instances, university officials said Wednesday.

UConn officials said nearly a dozen scientific journals are being warned of the potential problems after publishing his studies in recent years.

The researcher, Dr. Dipak Das, did some studies of resveratrol, an ingredient in red wine that has shown potential for promoting health.

But Dr. Nir Barzilai, whose research team conducts resveratrol research at the Albert Einstein College of Medicine in New York, told The Associated Press that Das is not a major figure in the field. The new allegations will not make a material difference to resveratrol research, which is being conducted extensively around the world with encouraging results from many labs, Barzilai said.
