Pseudogap regime for the prototype high-Tc compounds hole dopedBi2Sr2CaCu2O8-x (Bi2212) and electron doped Nd2-xCexCuO4 (NCCO) is described bymeans of novel generalized LDA+DMFT+Sk approach. Here conventional dynamicalmean-field theory (DMFT) equations are supplied with additional (momentumdependent) self-energy Sk. In the present case Sk describes non-local dynamicalcorrelations induced by short-ranged collective Heisenberg-likeantiferromagnetic spin fluctuations. Material specific model parameters of twoneighboring CuO2 layers of Bi2212 and single CuO2 layer of NCCO were obtainedwithin local density approximation (LDA) and constrained LDA method. We showthat Fermi surface in presence of the pseudogap fluctuations have perfectlyvisible "hot-spots" for NCCO while in Bi2212 there is just rather broad regionwith strong antiferromagnetic scattering. Results obtained are in goodagreement with recent ARPES and optical experiments.
