Newly characterized interaction stabilizes DNA structure: oligoethylene glycols stabilize G-quadruplexes CH–π interactions [PDF]

open access: yes, 2017
Oligoethylene glycols are used as crowding agents in experiments that aim to understand the effects of intracellular environments on DNAs. Moreover, DNAs with covalently attached oligoethylene glycols are used as cargo carriers for drug delivery systems.

Relationship between Friction Coefficient, Contact Angle and Infrared Absorbance of Polypropylene Glycol on Metal Surface

open access: yesTribology Online, 2013
The kinematic viscosities in the undiluted solutions of propylene glycol and the polypropylene glycols were proportional to their molecular weights, but the friction coefficients and compressibilities in polypropylene glycols hardly depended on their ...

ESI-MS/MS for the Differentiation of Diastereomeric Pyrimidine Glycols in Mononucleosides

open access: yes, 2016
Pyrimidine glycols, or 5,6-dihydroxy-5,6-dihydropyrimidines, are primary lesions in DNA induced by reactive oxygen species. In this article, we report the preparation and tandem mass spectrometry (MS/MS) characterization of the two cis diastereomers of ...
