Comment on 'Resonance Raman Investigation of (Ru(phen)2(dppz)2+) and related complexes in water and in the presence of DNA.'

Article Abstract:

Some of the results of a study conducted by W. Chen, et al, on the interaction between (Ru(phen)2dppz)2+ and DNA invite comment. The lowest excited state of ruthenium(II) dppz complexes generated confusion resulting from data for rhenium-(I) dppz complexes. Chen's suggestion on the identity of the species responsible for TR2 spectra was also unlikely. In addition, the researchers should have considered the detection of the pseudo-steady-state population during a 10 ns laser pulse.

Potential function describing the folding of the 30 nm fiber

Article Abstract:

A study was conducted to show the incorporation of an attractive-repulsive potential into an elastic rod model of DNA to characterize the 30 nm fiber. An energy landscape for the 30 nm fiber was modeled. A technique of integrating a Lennard-Jones type potential function into the elastic rod model was also developed. Experimental results indicated that a twist excess or deficit can unfold the 30 nm fiber.

Thermotropic phase behavior of cationic lipid-DNA complexes compared to binary lipid mixtures

Article Abstract:

Research is presented examining the thermotropic phase behavior of zwitterionic/cationic binary lipid mixtures and comparing this to its lipidic phase diagram of mixtures complexed with DNA.
