  On the basis of the Brueckner-Hartree-Fock method with the nucleon-nucleon
forces obtained from lattice QCD simulations, the properties of the
medium-heavy doubly-magic nuclei such as 16^O and 40^Ca are investigated. We
found that those nuclei are bound for the pseudo-scalar meson mass M_PS ~ 470
MeV. The mass number dependence of the binding energies, single-particle
spectra and density distributions are qualitatively consistent with those
expected from empirical data at the physical point, although these hypothetical
nuclei at heavy quark mass have smaller binding energies than the real nuclei.
