McKinnon and coauthors propose a model in which Io's continuous volcanism and terrain burial (driven by very strong tidal heating) naturally lead to such unstable topography - primarily by creating very large confining stresses as...UCSF study of HIV patients identifies interleukin-7 as a key factor in controlling T-cells

...whites. "In Maryland, at least, African Americans undergoing elective CEA do not do as well as whites because their care is more likely to be delivered in hospitals where fewer CEAs are performed and by surgeons who are less experienced," says Bruce Perler, M.D., professor of surgery at Johns Hopkins.
