Virus Replication as a Phenotypic Version of Polynucleotide Evolution [PDF]

open access: yesBulletin of Mathematical Biology, April 2013, Volume 75, Issue 4, pp 602-628, 2013
In this paper we revisit and adapt to viral evolution an approach based on the theory of branching process advanced by Demetrius, Schuster and Sigmund ("Polynucleotide evolution and branching processes", Bull. Math. Biol.

Pulling hairpinned polynucleotide chains: Does base-pair stacking interaction matter? [PDF]

open access: yesJ. Chem. Phys. 114, 8694-8700 (2001). AIP Copyright, 2001
Force-induced structural transitions both in relatively random and in designed single-stranded DNA (ssDNA) chains are studied theoretically. At high salt conditions, ssDNA forms compacted hairpin patterns stabilized by base-pairing and base-pair stacking

On the Lubensky-Nelson model of polymer translocation through nanopores [PDF]

open access: yesBiophys. J. 103, 889 (2012), 2012
We revisit the one-dimensional stochastic model of Lubensky and Nelson [Biophys. J 77, 1824 (1999)] for the electrically driven translocation of polynucleotides through alpha-hemolysin pores.

Solvation Effects on Hole Mobility in the Poly G/Poly C Duplex [PDF]

open access: yesRussian Journal of Physical Chemistry A, 86, 832-836 (2012), 2012
Theoretical calculations of solvation contribution to hole energy in a polynucleotide chain give very low hole mobility values at zero temperature, \mu < 10^{-3} cm^2/(V s).

Complexation of DNA with Cationic Surfactant [PDF]

open access: yes, 1999
Transfection of an anionic polynucleotide through a negatively charged membrane is an important problem in genetic engineering. The direct association of cationic surfactant to DNA decreases the effective negative charge of the nucleic acid, allowing the

Driven Polymer Translocation Through a Narrow Pore [PDF]

open access: yes, 1999
Motivated by experiments in which a polynucleotide is driven through a proteinaceous pore by an electric field, we study the diffusive motion of a polymer threaded through a narrow channel with which it may have strong interactions. We show that there is

Complex Formation Between Polyelectrolytes and Ionic Surfactants [PDF]

open access: yes, 1998
The interaction between polyelectrolyte and ionic surfactant is of great importance in different areas of chemistry and biology. In this paper we present a theory of polyelectrolyte ionic-surfactant solutions.

Viral Evolution and Adaptation as a Multivariate Branching Process [PDF]

open access: yes, 2013
In the present work we analyze the problem of adaptation and evolution of RNA virus populations, by defining the basic stochastic model as a multivariate branching process in close relation with the branching process advanced by Demetrius, Schuster and ...

An Innovative Lip Boosting Technique Using Polynucleotides: "4-point Cannula Technique". [PDF]

open access: yesPlast Reconstr Surg Glob Open
Summary:. The new concept in aesthetic medicine is heading toward regenerative medicine and the use of skin boosters in our practice, so the present case report aimed to evaluate the efficacy of injecting a polynucleotide into the lips for lip ...
