Increasing benefit seen in novel drug that treats Gleevec resistance
...aterial in bone marrow stem cells that produces an abnormality
called the Philadelphia chromosome. This chromosome contains a new fused-together gene, BCR-ABL, which produces an enzyme that switches on uncontrolled growth in the bone marrow cell. Gleevec binds to this Bcr-Abl enzyme, shutting down its activity, ...

Study shows new imaging tracer clarifies cause of chest pain up to 30 hours after pain stops
...parison showed the two tracers pointed to the same abnormality
