THERMOGRAVIMETRIC STUDY OF THE FORMATION OF CROSS-LINKED STRUCTURES IN THE SYNTHESIS OF POLY(METHYLSILOXANE)
(Sociedad Chilena de Química, 2003)
SIM-XL: A powerful and user-friendly tool for peptide cross-linking analysis
(Elsevier B.V., 2015-11-03)
Chemical cross-linking has emerged as a powerful approach for the structural characterization of proteins and protein complexes. However, the correct identification of covalently linked (cross-linked or XL) peptides analyzed ...
Insights into the impact of cross-linking processes on physicochemical characteristics and mucoadhesive potential of gellan gum/retrograded starch microparticles as a platform for colonic drug release
Polymer microparticles have been regarded a promising system for drug delivery. In this paper, ionic cross-linking (IC) and dual cross-linking (DC) (ionic/covalent) processes were addressed for the design of innovative ...
Modeling a system of phosphated cross-linked high amylose for controlled drug release. Part 2: Physical parameters, cross-linking degrees and drug delivery relationships
(Elsevier B.V., 2009-04-17)
High amylose cross-linked to different degrees with sodium trimetaphosphate by varying base strength (2% or 4%) and contact time (0.5-4 h) was evaluated as non-compacted systems for sodium diclophenac controlled release. ...
Insights into the swelling process and drug release mechanisms from cross-linked pectin/high amylose starch matrices
Cross-linked pectin/high amylose mixtures were evaluated as a new excipient for matrix tablets formulations, since the mixing of polymers and cross-linking reaction represent rational tools to reach materials with modulated ...
Influence of cross-linking density on swelling and estradiol permeation of chitosan membranes
Chitosan membranes were obtained by a casting/solvent evaporation method and cross-linking with sodium tripolyphosphate. The effect of cross-linking time was studied and the cross-linked membranes were characterized with ...
Physical properties of pectin-high amylose starch mixtures cross-linked with sodium trimetaphosphate
(Elsevier B.V., 2012-02-28)
Pectin-high amylose starch mixtures (1:4; 1:1; 4:1) were cross-linked at different degrees and characterized by rheological, thermal, X-ray diffraction and NMR analyses. For comparison, samples without cross-linker addition ...
Influence of phosphated cross-linked high amylose on in vitro release of different drugs
(Elsevier B.V., 2009-11-17)
The influence of structural characteristics of high amylose cross-linked at different degrees on the release of drugs with important molecular differences, namely sodium diclophenac (SD) and nicotinamide (NI), was assessed ...
