Chitosan films were plasticized with four hydrophilic compounds, namely, glycerol (GLY), ethylene glycol (EG), poly(ethylene glycol) (PEG), and propylene glycol (PG). Our objective was to investigate the effect of plasticizers on mechanical and surface properties of chitosan films. The stability of plasticized films was observed by storage for 3 and 20 weeks in an environmental chamber at 50 +/...

background and objectives: preparation and evaluation of nanocomposite films have become prevalent in recent years. depending on the purpose of using the film, and considering the effects and interaction effects of nanomaterial and other modifiers on the film properties, the amounts of nanomaterials and modifiers should be optimized. the effects of montmorillonite (mmt), glycerol (gl), and thei...

The composition factors of Kac-modules for the general linear Lie superalgebra gl m|n is explicitly determined. In particular, a conjecture of Hughes, King and van der Jeugt in [J. Math. Phys., 41 (2000), 5064-5087] is proved.

Synthetic and natural polymers are often used as drug delivery systems in vitro and in vivo. Biodegradable chitosan of different sizes were used to encapsulate antitumor drug tamoxifen (Tam) and its metabolites 4-hydroxytamoxifen (4-Hydroxytam) and endoxifen (Endox). The interactions of tamoxifen and its metabolites with chitosan 15, 100 and 200 KD were investigated in aqueous solution, using F...

This study was carried out to investigate the capacity of chitosan and wheat bran to protect against high fat diet-induced hepatic steatosis. MATERIALS AND METHODS: Thirty six adult male Sprague-Dawley rats (average body weight of 120-150 g) were randomly assigned to six groups (n=6 rats/group) and fed on one of the following experimental diets: (i) basal diet, negative control; (ii) basal diet...

Selective isolation of Kunitz trypsin inhibitor (KTI) and lectin from soybean whey solutions by different types of chitosan beads was investigated. The chitosan beads were co-crosslinked with tripolyphosphate/genipin in solutions at pH 5, 7 or 9 (CB5, CB7, CB9). The maximum adsorption ratios of chitosan beads to KTI and lectin were observed at pH 4.4 and 5.4, respectively; highly selective sepa...

A new biocomposite cross-linked glutaraldehyde-chitosan/MgO/Fe3O4 (CTS-GL/MgO/Fe3O4) adsorbent with magneto-responsiveness was prepared and applied for the removal of reactive blue 19 (RB-19), a synthetic textile dye. The CTS-GL/MgO/Fe3O4 structurally characterized using spectroscopic (XRD, FTIR, SEM–EDX), its physicochemical properties were evaluated potentiometry pHpzc analyses. influence var...

The possibility of using glycol chitosan to obtain stabilized liposome containers for doxorubicin delivery is demonstrated. The dissociation constants of the liposome complexes with glycol chitosan (3.4 × 10–4 and 1.10 × 10–5 depending on the aggregation state of the liposomes) are determined. It is shown that the formation of liposome complexes with glycol chitosan has a significant prolongati...
