Gene therapy has been developed as an important strategy in field of cancer therapies. But it was always puzzled by low transfection efficacy. In this study, th
The spectrum of highly ionized nickel in the region of 12-40 nm was studied by means of the beamfoil method. Nickel ions of 45 and 70 MeV energy from the HI-13
