Consensus report on the use of PN‐HPT™ (polynucleotides highly purified technology) in aesthetic medicine

open access: yesJournal of Cosmetic Dermatology, 2020
Injective procedures using polynucleotides‐based products to promote dermal rejuvenation and revitalization are steadily evolving, yet no structured protocols are available that discuss and provide guidance in aesthetic treatments with highly purified ...

Fluorescent labeling of plasmid DNA and mRNA : gains and losses of current labeling strategies [PDF]

open access: yes, 2016
Live-cell imaging has provided the life sciences with insights into the cell biology and dynamics. Fluorescent labeling of target molecules proves to be indispensable in this regard. In this Review, we focus on the current fluorescent labeling strategies

Nucleic acid vibrational circular dichroism, absorption, and linear dichroism spectra. I. A DeVoe theory approach [PDF]

open access: yes, 1997
Infrared (IR) vibrational circular dichroism (VCD), absorption, and linear dichroism (LD) spectra of four homopolyribonucleotides, poly(rA), poly(rG), poly(rC), and poly(rU), have been calculated, in the 1750–1550 cm-1 spectral region, using the DeVoe ...

Dry/Wet Cycling and the Thermodynamics and Kinetics of Prebiotic Polymer Synthesis

open access: yesLife, 2016
The endoergic nature of protein and nucleic acid assembly in aqueous media presents two questions that are fundamental to the understanding of life’s origins: (i) how did the polymers arise in an aqueous prebiotic world; and (ii) once formed in some ...

Fast microwave heating-based one-step synthesis of DNA and RNA modified gold nanoparticles

open access: yesNature Communications, 2022
Simple methods for attaching polynucleotides to gold nanoparticles are of interest for simplifying conjugation in a range of applications. Here, the authors report a microwave heating-based method for the fast, one-step attachment of a range of thiolated

Dependence of the nature of the Holstein polaron motion in a polynucleotide chain subjected to a constant electric field on the initial polaron state and the parameters of the chain [PDF]

open access: yes, 2021
In this work, we consider the motion of a polaron in a polynucleotide Holstein molecular chain in a constant electric field. It is shown that the character of the polaron motion in the chain depends not only on the chosen parameters of the chain, but also on the initial distribution of the charge along the chain.

A Raman spectroscopic study of the interaction between nucleotides and the DNA binding protein gp32 of bacteriophage T4 [PDF]

open access: yes, 1987
Raman spectra of the bacteriophage T4 denaturing protein gp32, its complex with the polynucleotides poly(rA), poly(dA), poly(dT), poly(rU), and poly(rC), and with the oligonucleotides (dA)8 and (dA)2, were recorded and interpreted.

An onset model of mutually catalytic self-replicative systems formed by an assembly of polynucleotides [PDF]

open access: yes, 2023
Self-replicability is the unique attribute observed in all the living organisms and the question how the life was physically initiated could be equivalent to the question how self-replicating informative polymers were formed in the abiotic material world.

Non-enzymatic oligonucleotide ligation in coacervate protocells sustains compartment-content coupling

open access: yesNature Communications, 2023
Modern cells are complex chemical compartments tightly regulated by an underlying DNA-encoded program. Achieving a form of coupling between molecular content, chemical reactions, and chassis in synthetic compartments represents a key step to the assembly
