Dipeptides Containing Pyrene and Modified Photochemically Reactive Tyrosine: Noncovalent and Covalent Binding to Polynucleotides [PDF]

Molecules, 2023
Dipeptides 1 and 2 were synthesized from unnatural amino acids containing pyrene as a fluorescent label and polynucleotide binding unit, and modified tyrosine as a photochemically reactive unit.

Stochastic Sensing of Polynucleotides Using Patterned Nanopores [PDF]

Physical Review X, 2012
The effect of the microscopic structure of a pore on polymer translocation is studied using Langevin dynamics simulation, and the consequence of introducing patterned stickiness inside the pore is investigated.

Translocation of structured polynucleotides through nanopores [PDF]

Physical Biology 1 (2004) 19-26, 2003
We investigate theoretically the translocation of structured RNA/DNA molecules through narrow pores which allow single but not double strands to pass. The unzipping of basepaired regions within the molecules presents significant kinetic barriers for the translocation process.

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

Biophys. 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. We show that the model correctly describes two further important properties of the experimentally observed translocation time distributions, namely their spread ...

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

J. 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 interactions, and a threshold external force is needed to pull the hairpinned structure into a ...

Driven Polymer Translocation Through a Narrow Pore [PDF]

, 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 a range of polymer lengths in which the system is approximately translationally invariant, and we ...

An Innovative Lip Boosting Technique Using Polynucleotides: “4-point Cannula Technique” [PDF]

Plastic and Reconstructive Surgery, Global 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 ...

Phenanthridine–pyrene conjugates as fluorescent probes for DNA/RNA and an inactive mutant of dipeptidyl peptidase enzyme [PDF]

Beilstein Journal of Organic Chemistry, 2023
Two novel conjugate molecules were designed: pyrene and phenanthridine-amino acid units with a different linker length between the aromatic fragments. Molecular modelling combined with spectrophotometric experiments revealed that in neutral and acidic ...

Results of Shoulder Adhesive Capsulitis Treatment With the Use of Platelet Rich Plasma and Nucleotide Drugs: A Comparative Study [PDF]

Travmatologiâ i Ortopediâ Rossii, 2022
Background. Intra-articular injections of autologous platelet-rich plasma (PRP), which is a natural biological stimulant and affects various parts of the regenerative process, are often used in the treatment of adhesive capsulitis.
