This paper contains examples of closed aspherical manifolds obtained as aby-product of recent work by the author [arXiv:math.GR/0509490] on the relativestrict hyperbolization of polyhedra. The following is proved.  (I) Any closed aspherical triangulated n-manifold M^n with hyperbolicfundamental group is a retract of a closed aspherical triangulated(n+1)-manifold N^(n+1) with hyperbolic fundamental group.  (II) If B_1,...,B_m are closed aspherical triangulated n-manifolds, thenthere is a closed aspherical triangulated manifold N of dimension n+1 such thatN has nonzero simplicial volume, N retracts to each B_k, and \pi_1(N) ishyperbolic relative to \pi_1(B_k)'s.  (III) Any finite aspherical simplicial complex is a retract of a closedaspherical triangulated manifold with positive simplicial volume andnon-elementary relatively hyperbolic fundamental group.Comment: This is the version published by Algebraic & Geometric Topology on 20  September 200
