A series of blend films comprised 88% hydrolyzed poly(vinyl alcohol) (PVA) with native cassava starch (NCS), high-oxidized (HCS), and pre-gelatinized (PCS) was prepared via solution casting. The blends were plasticized glycerol or glycerol-sorbitol mixture. structure each film characterized by Fourier-transform infrared spectroscopy X-ray diffraction analysis. Cross-sections the PVA/HCS PVA/PCS...

Nurses have shown a weakness both in recognising different types of exudate and in choosing an appropriate dressing (Smith and Gibson, 2011). In order to support nurses in identifying the correct dressing choice, an exudate wound decision algorithm has been developed. The algorithm suggests the type of dressing required for bleeding and infected wounds is a calcium alginate dressing with a silv...

In order to provide health benefits potential probiotic strains must be viable and metabolically active in the product and maintance their activity in gastrointestinal tract (GIT). Therefore, the current investigations are based on protection of probiotics by microencapsulation to increase survival and delivery of bacterial cultures to the GIT. Several reports have shown better survival of enca...

Results from the present study have shown that the ionic species of buffers, pH values and reaction temperature can affect the enzyme unit activities and product specificity of Toruzyme (Novo Nordisk A/S Bagsvaerd, Denmark) CGTase (cyclodextrin glucanotransferase). Applying a similar reaction environment (acetate buffer, pH 6.0; temperature, 60 degrees C), the CGTase was found to be capable of ...

The nanocomposite web of calcium alginate and polyvinyl alcohol with varying proportion has been prepared by electrospinning and its application for wound healing is examined. Scanning electron microscope and Fourier transform infrared spectroscopy have been used to characterize the morphology and molecular fingerprint. The water vapour transmission rate of the blended nanofibre composite web h...

the present work investigated the preparation of biodegradable beads with alginate polymer by ionotropic gelation method to improve the control release properties of the antibiotic rifampicin. ionotropic gelation method was applied to prepare beads using calcium chloride (cacl2) as cationic component and alginate as an anionic component. in this method, adding 0.5% w/v polyvinyl alcohol (pva) t...
