Cytosine glycols (5,6-dihydroxy-5,6-dihydrocytosine) are initial products of cytosine oxidation. Because these products are not stable, virtually all biological studies have focused on the stable oxidation products of cytosine, including 5-hydroxycytosine, uracil glycols and 5-hydroxyuracil. Previously, we reported that the lifetime of cytosine glycols was greatly enhanced in double-stranded DN...

The separation of polyethylene glycols (PEGs) into single homologs by reversed-phase chromatography is investigated experimentally and theoretically. used core–shell column shown to achieve the baseline PEG up molar weights at least 5000 g/mol. A detailed study performed elucidating role operating conditions, including temperature, eluent composition, degree polymerization polymer. Applying Mar...

Dendrimers are macromolecular hyperbranched nano-structures, which properties mainly driven by the type of their terminal functions. This paper reports synthesis dendritic structures built from difunctional polyethylene glycols (PEGs) used as core. Three different PEG lengths have been used: PEG300 (ca 6 CH2CH2-O units), PEG1000 22 and PEG2000 45 units). The first level branching units is based...

This study evidences the adsorption of model nonionic polymers onto aluminogermanate imogolite nanotubes, attractive porous nanofillers with potential molecular loading and release applications. We resolve underlying mechanisms between nanotubes polyethylene glycols different weights by means nanoisothermal titration calorimetry. The analysis results provides a direct thermodynamic characteriza...
