3D printing technology has great potential for the reconstruction of human skin. However, reconstructed skin some differences from natural skin, largely because hydrogel used does not have appropriate biological and physical properties to allow healing regeneration. This study examines swelling, degradability, microstructure Collagen/Sodium Alginate (Col/SA) hydrogels differing compositions pur...

Starch was isolated from cocoyam (Xanthosoma sagittifolium). It was further modified by acetylation using NaOH and NaHCO3 at room temperature (28±3 oC). The pasting and physicochemical properties of the native and modified starches were then studied. Pasting properties of the alkaline modified cocoyam starches showed higher peak viscosities (245.92-256.96 RVU) compared to low peak viscosity (21...

The purpose of this study is to develop novel intestinal-specific drug delivery systems with pH sensitive swelling and drug release properties. Methacrylic-type polymeric prodrugs were synthesized by free radical copolymerization of methacrylic acid, poly(ethyleneglycol monomethyl ether methacrylate) and a methacrylic derivative of N-(4-hydroxyphenyl)-2-(4-methoxyphenyl) acetamide in the presen...

Liver diseases have been a medical problem which is difficult to manage. Some of the problems in the treatment of these diseases lie in the lack of reliable drug available. Curcumin, an active ingredient of the rhizomes of plant Curcuma has been investigated in the treatment of various disorders incuding liver diseases. The therapeutic effects of curcumin on liver diseases have been thought to ...

Abstract The influence mechanism of basicity on the reduction swelling index (RSI) iron ore briquettes was investigated using SEM analysis and Factsage 7.3 thermodynamic calculations based addition pure CaO to Bayan Obo concentrate. results revealed that solid solution Ca 2+ in FeO lattice increased with briquettes, whereas diffusion channels Fe ions during process from resulted formation a gre...
