High-precision mass measurements of stable and beta-decaying nuclides 52-57Cr, 55Mn, 56,59Fe, 59Co, 75, 77-79Ga, and the lanthanide nuclides 140Ce, 140Nd, 160Yb, 168Lu, 178Yb 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 168Lu in its isomeric state has been measured directly. The mass of neutron-rich 178Yb indicates a change of nuclear structure approaching the double harmonic-oscillator shell closure for
