Purpose: Following gynecologic surgery, postoperative adhesions commonly cause intestinal obstruction; therefore, the anti-adhesion materials used are of great importance. Currently, various used, including regenerated cellulose (Interceed, Johnson and Johnson, Ltd) carboxymethylcellulose hyaluronate (Seprafilm, Kaken Pharmaceutical, Ltd).

Surgicel® (regenerated oxidized cellulose) is a bio-absorbable hemostatic material widely applied to prevent surgery-derived adhesions. Some critical issues have been reported associated with this biomaterial, which we aimed overcome by producing bacterial nanocellulose (BNC) membranes activity, through electrochemical oxidation using the tetramethylpiperidine-1-oxyl (TEMPO) radical. Samples we...

A previous study has demonstrated a progression in the nerve regeneration by polyaniline/cellulose (PANI/RC), although the underlying mechanism was not elucidated. In the present study, regenerated nerves were investigated, using histological techniques, functional assays and western blot analysis. The triceps surae muscle weight ratio percentages of the sham, regenerated cellulose (RC) and the...

Bacterial cellulose was produced by Acetobacter xylinum (strain TISTR 975). Bacterial cellulose is an interesting material for using as a wound dressing since it provides moist environment to a wound resulting in a better wound healing. However, bacterial cellulose itself has no antimicrobial activity to prevent wound infection. To achieve antimicrobial activity, silver nanoparticles were impre...

Regenerated cellulose nanoparticles (RCNs) including both elongated fiber and spherical structures were prepared from microcrystalline cellulose (MCC) and cotton using 1-butyl-3-methylimidazolium chloride followed by high-pressure homogenization. The crystalline structure of RCNs was cellulose II in contrast to the cellulose I form of the starting materials. Also, the RCNs have decreased crysta...

The effect of either high-cellulose (15%) or regular-cellulose (5%) diets on fecal bacterial glycosidases was assessed in two groups of ten Wistar rats, each given an injection of 1,2-dimethylhydrazone, and in two groups of six control rats. During a 4-month period, fecal activities of bacterial beta-galactosidase and beta-acetylglucosaminidase were reduced markedly in control rats maintained o...

The yield and properties of cellulose produced from bacterial fermentation of black tea broth (known as Kombucha) were investigated in this study. The tea broth was fermented naturally over a period of up to 8 days in the presence of sucrose. Tea broth with a sucrose concentration of 90 g/l produced highest yield of bacterial cellulose (66.9%). The thickness and yield of bacterial cellulose inc...

The effect of either high-cellulose (15%) or regular-cellulose (5%) diets on fecal bacterial glycosidases was assessed in two groups of ten Wistar rats, each given an injection of 1,2-dimethylhydrazone, and in two groups of six control rats. During a 4-month period, fecal activities of bacterial /3-galactosidase and /3-acetylglucosaminidase were reduced markedly in control rats maintained on th...

The effect of bacterial cellulose (BC) on the freeze-thaw stability of rice starch gels during 5 freeze-thaw cycles were investigated, using scanning electron microscopy (SEM), rapid visco analyzer (RVA), X-ray diffractometry (XRD), differential scanning calorimetry (DSC) and textural analyzer (TA). SEM micrographs of freeze-thaw gels showed that smaller pore size and a thicker surrounding matr...

The hydrophilic property of cellulose is a key limiting factor for its wide application. Here, a novel solution impregnation pathway was developed to increase the hydrophobic properties of cellulose. When compared with the regenerated cellulose (RC), the composite films showed a decrease in water uptake ability towards water vapor, and an increase of the water contact angle from 29° to 65° with...
