BACKGROUND/PURPOSE It is still under discussion which is the best tissue augmenting substance for the endoscopic treatment of children with vesicoureteral reflux (VUR). We describe our preliminary experience (September 2009-November 2011) with polyacrylate-polyalcohol copolymer hydrogel (PPCH). METHODS This is an observational, descriptive, prospective study which included 81 female and male ...

Polyelectrolyte multilayer films assembled from a hydrophobic N-alkylated polyethylenimine and a hydrophilic polyacrylate were discovered to exhibit strong antifouling, as well as antimicrobial, activities. Surfaces coated with these layer-by-layer (LbL) films, which range from 6 to 10 bilayers (up to 45 nm in thickness), adsorbed up to 20 times less protein from blood plasma than the uncoated ...

Absorbent recycled paper products were tested and compared with a sodium polyacrylate gelling agent, Aquatain, for solidifying larval diets of the screwworm, Cochliomyia hominivorax (Coquerel). A recycled newsprint product, Terra-Mulch, when mixed with water and dietary ingredients produced a diet medium of homogeneous texture that supported larval growth and development comparable to the stand...

The swelling behavior of fully neutralized sodium polyacrylate gels was investigated in aqueous solutions of alkali metal (LiCl, NaCl, KCl, CsCl) and alkaline earth metal salts (CaCl2, SrCl2, BaCl2). The total salt concentration and the ratio of monovalent to divalent cations were varied in the biologically significant range. It is found that the concentrations of both monovalent and divalent c...

Despite the low cost and high ionic conductivity of aqueous electrolytes, their practical applications are limited because a withstand voltage 1.2 V The energy density increases in proportion to which is crucial factor for electric double-layer capacitors (EDLCs) with solid polymer electrolytes. In this study, electrolyte solution was made into viscous improve electrolyte. prepared from sodium ...

T he process of debridement is an important step in the preparation of the wound bed in chronic wounds. Ways in which wound debridement can be achieved include surgical, sharp, mechanical, enzymatic and autolytic debridement. Expert opinion and clinical experience suggest that removal of the material such as necrotic tissue and fibrinous slough from the surface of a wound is necessary for the p...

in this article, hybrid organic-inorganic materials were prepared by free radical copolymerization of 2-hydroxyethyl methacrylate (hema) and 3-methacryloxy-propyltrimethoxysilane (mptms) via sol-gel process. the methoxysilane-containing copolymer precursors were synthesized at different compositions. these copolymer precursors were then hydrolyzed and condensed to produce phema-sio2 nanocomposi...

A highly absorbent cellulose fiber from recycled paper was tested and compared with a polyacrylate gelling agent, Aquatain, normally used for bulking and solidifying larval rearing medium of screwworm, Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae). The absorbent fiber, when mixed with water and dietary ingredients, produced a diet medium of homogeneous texture that supported larva...

The transport of microscale carbonyl iron powder suspensions modified with anionic homopolymers was studied in water-saturated sand columns containing well-dispersed hydrophobic sand grains. Sand grains functionalized with hexadecyltrimethoxysilane were coated with a eutectic mixture of dichlorobenzenes that was solid at -10 °C and was mixed by grinding with unmodified sand grains. The dichloro...
