Abstract
The review summarizes certain theoretical and experimental studies of the quasiparticle, J, and Josephson, IJ, currents between superconductors partially dielectrized with charge-density waves (CDWs). A relation between the Cooper and electron-hole pairings and their manifestations in high-Tc oxides have been analyzed. It was shown that the CDW fingerprints can be found in a lot of already observed dependences. All described results are considered in the framework of the historical context.
