Curvature and charge modulations in Lamellar DNA-lipid complexes
Article Abstract:
A free energy functional that includes the electrostatic, lipid mixing, and elastic degrees of freedom in a self-consistent manner is used to model the possible formation of coupled spatial corrugations and charge density modulations in lamellar DNA- lipid complexes. It is found that the balance of forces favors membrane corrugations that are expected to be stable with respect to thermal membrane undulations for a certain range of lipid composition.

Enveloping of charged proteins by lipid bilayers
Article Abstract:
The ability of mixed lipid bilayers to envelop colloidal particles such as proteins provides a possible mechanism for drug delivery through cell membranes is studied. It is found that, using a simple theoretical approach, that enveloping of charged proteins is feasible for mixed (charged-neutral) lipid bilayers, provided the spontaneous curvature of the neutral lipid is not too far from the radius of the protein.

Charge transfer excited-state dynamic in DNA duplexes substituted with an ethynylpyrenyldeoxyuridine electron source and a fluorodeoxyuridine ron trap
Article Abstract:
Six DNA duplexes are studied at 10 degree Celsius, in order to observe PY(super .+)/dU(super .-) CT excited-state dynamics in them following photoexcitation at 355nm. The results suggest that the excess electron in the PY(super .+)/dU(super .-) state of U(super PY) is restrained from hopping to nearby U(super F) traps due to attraction to PY(super .+).
