The surface tension and density of distilled water, physiological solution and salt solutions of the DNA, irradiated by nonthermal coherent millimeter electromagnetic waves with the frequencies 64.5, 50.3, and 48.3 GHz are investigated. The measurements of test samples show that due to irradiation the surface tension does not change within the experimental error. The densities of physiological solution...
Spectrophotometry and microcalorimetry have been employed to investigate the melting of DNA complexes with the anti-tumour compound mitoxanthrone for ionic strengths of 0.11 and 0.011 M NaCl. It is shown that at 0.011 M NaCl the dependence of the melting point (T m ) on the concentration of mitoxanthrone passes through a minimum, and T m falls in the region where there is one mitoxanthrone...
