      Chang, Megan A.; Morgado, Micaela; Warren, Curtis R.; Hinton, Cimona V.; Farach-Carson, Mary C.; Delk, Nikki A. (2014)
      BACKGROUND: Bone marrow stromal cell (BMSC) paracrine factor(s) can induce apoptosis in bone metastatic prostate cancer (PCa) cell lines. However, the PCa cells that escape BMSC-induced apoptosis can upregulate cytoprotective ...
    • Pacific plate deformation from horizontal thermal contraction 

      Kreemer, Corné; Gordon, Richard G. (2014)
      The central approximation of plate tectonics is that the plates are rigid, which gives the theory its rigor and predictive power. Space geodetic measurements are consistent with the rigidity of stable plate interiors, but ...
