- Abstract:
- ... Fibres have been used extensively in wound dressing applications as they provide a high surface area for absorption, ease of fabrication and softness. It is common practice for commercial wound dressings to be produced from natural materials, such a marine polysaccharides, as they are predominantly biocompatible, non-toxic, and often display bioactive properties, such as inherent antimicrobial act ...

- Abstract:
- ... The Tricholoma matsutake polysaccharides (TMP) extraction was optimized using counter-current probe ultrasonic extraction (CCPUE) by response surface methodology (RSM). The effect of three factors (liquid–solid ratio, extraction time and pulse duration) on the TMP yield was studied. The results showed that the optimal conditions were liquid–solid ratio (15), extraction time (61min) and pulse durat ...

- Abstract:
- ... The idea of this study was to combine hyaluronic acid (HA) viscosupplementation and a local/controlled delivery of a hydrophobic anti-inflammatory drug. To this aim, we investigated the ability of an octenyl succinic anhydride (OSA) modified HA (OSA–HA), to act as a solubility enhancer and as a platform for slow release of hydrophobic drug(s). This novel HA derivative could act as a viscosupplemen ...

The sorption data of an anionic dye on cellulose fiber are often correlated with a log-linear model to determine the internal accessible volume of the fiber to the anionic dye (V, L/kg) and as such the standard affinity of the anionic dye to the fiber (−Δμ°, J/mol), but without taking into account the influence of ionized carboxyl groups due to cellulose oxidation ([COO−]f, mol/kg). In this study, ...

A precooled aqueous solution of 7wt% NaOH/12wt% urea was used to dissolve cellulose up to a concentration of 2wt%, which was then coagulated in an acetone/water mixture to regenerate cellulose film. The volume ratio of acetone to water (φ) had a dominant influence on film dimensional stability, film-forming ability, micromorphology, and mechanical strength. The film regenerated at φ=2.0 showed exc ...
