• This reports our recent studies on changes in properties of heavy hadrons containing at least a charm or a bottom quark in nuclear matter, and the results for the Λ^+_c and Λ_b hypernuclei are studied quantitatively. Comparisons are made with the results for the Λ hypernuclei studied previously in the same approach. It is shown that although the scalar and vector potentials for the Λ, Λ^+_c and Λ_b in the hypernuclei multiplet with the same baryon numbers are quite similar, the wave functions obtained, e.g., for 1s_<1/2> state, are very different. The Λ^+_c probability density distribution in ^<209>_<Λ^+_c>Pb is much more pushed away from the center than that for the Λ in ^<209>_ΛPb due to the Coulomb force. On the contrary, the Λ_b probability density distributions in Λ_b hypernuclei are much larger near the origin than those for the Λ in the Λ hypernuclei due to its heavy mass. A possibility of B^- nuclear bound (atomic) states is also briefly discussed.
