By using the statistical model and recent theoretical predictions of nuclear properties, survival probabilities of superheavy nuclei with respect to the xn evaporation channel ( x = 1-4) are calculated. Level densities of the Fermi-gas model and of a model with collective enhancement are used. The survival probabilities and the fusion cross-sections calculated within the dinuclear system model are applied to obtain excitation functions of No isotopes in the reactions 48Ca + 204, 206, 208Pb and production cross-sections of superheavy nuclei with Z > 102 in cold and hot fusion reactions. The results are in a good agreement with available experimental data.
