SACRAMENTO, Calif. (AP) — Two University of California, Davis neurosurgeons have been banned from performing medical research on humans after they were accused of experimenting on dying brain cancer patients without university permission, the Sacramento Bee reported Sunday (http://bit.ly/SP3nFi ).

J. Paul Muizelaar and Rudolph Schrot were banned from any research on humans after the university told the federal government that both surgeons took part in what the school termed “serious and continuing noncompliance” with federal regulations, the newspaper said.
