We develop an approach for incorporating both medium and off-shell effects in the calculation of full-folding nucleon-nucleus optical potentials for elastic scattering. The approach is based on a flexible scheme for calculating the nucleon-nucleon effective interaction in the nuclear medium. Using this scheme, we calculate a fully off-shell, energy-dependent effective force which includes effects arising from Pauli blocking and the nuclear mean field via an interacting nuclear matter model. Calculations of the elastic scattering observables for {ital p}+{sup 40}Ca and for {ital p}+{sup 208}Pb at energies between 30 and 400 MeV are presented and discussed. We also study total cross sections for neutron scattering off {sup 40}Ca, {sup 90}Zr, and {sup 208}Pb in the 5--400 MeV energy range. The theory gives a reasonable overall description of the data in the energy range under study.
