.High-precision mass measurements of stable and beta-decaying nuclides Cr52-57, Mn-55, Fe-56,Fe-59, Co-59, Ga-75,Ga- 77-79, and the lanthanide nuclides Ce-140, Nd-140, Yb-160, Lu-168, Yb-178 have been performed with the Penning-trap mass spectrometer ISOLTRAP at ISOLDE/CERN. The new data are entered into the Atomic Mass Evaluation and improve the accuracy of masses along the valley of stability, strengthening the so-called backbone. The mass of neutron-deficient Lu-168 in its isomeric state has been measured directly. The mass of neutron-rich Yb-178 indicates a change of nuclear structure approaching the double harmonic-oscillator shell closure for Z=70 and N=112
