“…This has been recently confirmed by other workers (Vasilescu, Teboul, Kranck & Gutmann, 1974). The only reported observation of nonwhite excess noise in an electrolytic system was in a solution of an electrolyte (BeSO4) in equilibrium with its precipitate under applied electrical field (Feher, 1970;Feher & Weissman, 1973).…”

Spectral analysis of electrical noise from various artificial membrane systems suggests that excess noise of an f-n spectral form, where n is approximately unity, is not primarily a bulk phenomenon simply dependent on the number of charge carriers. Measurements from aqueous and nonaqueous electrolytic resistors, comprised of several different ionic species, show only flat power density spectra under applied currents, even at extreme dilutions. Excess noise of f-n form is observed under applied d-c current in single pore membranes, as previously reported, but is also seen in multipore and polymer mesh membranes. Calculations based on single pore membrane noise data are in significant variance with the bulk charge carrier model proposed by Hooge. These observations suggest that such excess noise occurs in conjunction with anisotropic constraints to ion flow.

“…Thus it results that at distances from the phosphate sites larger than 5 A, the bulk may be represented by an electric noise created by point charges (i.e., the thermal noise produced by the Brownian motion of ions in an electrolyte; see, for instance, Vasilescu et al [27]). Under this condition the assumptions developed by Schildkraut and Lifson in their phenomenological model [24] are justified also in our case.…”

Sulfur-containing molecules-and particularly the aminothiol class-are radioprotector agents. Electrostatic interactions occur between the cationic forms of these radioprotectors and the phosphate groups of DNA or the polar head of lecithin. Some electrostatic properties of four representative drugs were studied: cysteamine, methyl-2-cystearnine, WR 2578 dephosphorylated, and WR 1065. The conformations of these molecules are computed by using the PCILO method. Then the distribution of the cationic charge is specified with the help of the a6 initio method. The electrostatic potential resulting from the Mulliken atomic net charge distribution is also calculated. The electrostatic and conformational results are in good agreement with previous experimental studies from this laboratory. In the case of the interaction with DNA, these radioprotectors act as normal counterions whose interaction with DNA phosphate sites is discussed.
