Silver nanoparticles-composing alginate/gelatine hydrogel improves wound healin...
Diniz, Flavia Resende; Maia, Romerito Cesar A. P.; Andrade, Lucas Rannier; Andrade, Luciana Nalone; Vinicius Chaud, Marco; Silva, Classius Ferreira daPolymer hydrogels have been suggested as dressing materials for the treatment of cutaneous wounds and tissue revitalization. In this work, we report the development of a hydrogel composed of natural polymers (sodium alginate and gelatin) and silver nanoparticles (AgNPs) with recognized antimicrobial activity for healing cutaneous lesions. For the development of the hydrogel, different ratios of sodium alginate ...
Chitosan/Copaiba oleoresin films for would dressing application
Debone, H. S.; Lopes, Patrícia Santos; Severino, Patrícia; Yoshida, Cristiana Maria Pedroso; Souto, Eliana B.; Silva, Classius Ferreira daBiopolymeric films can be used as dressings for the treatment of skin burns and other chronic wounds. The healing properties of these films may be enhanced by the addition of Copaiba oil (Copaifera L.) which properties have already been well-described. The aim of this study was to evaluate the addition of Copaiba oil in chitosan films prepared by casting solvent evaporation technique using chitosan solution (2%...
Natural polysaccharides in wound dressing applications
Yassue-Cordeiro, Patrícia Hissae; Severino, Patrícia; Souto, Eliana B.; Yoshida, Cristiana Maria Pedroso; Silva, Classius Ferreira daThis chapter discusses one innovative pharmaceutical form: the so-called two-dimensional system or flat system. They can be subdivided into films (or membranes), or even fabrics. The main applications of these systems are in the development of controlled release formulations, wound dressings, and in tissue engineering. This chapter focuses on the wound dressings for healing. A brief conceptualization and introd...
Development of chitosan/silver sulfadiazine/zeolite composite films for wound d...
Yassue-Cordeiro, Patricia Hissae; Zandonai, Cássio Henrique; Genesi, Bianca Pereira; Lopes, Patrícia Santos; Sanchez-Lopez, Elena; Garcia, Maria LuisaBiopolymeric films with silver sulfadiazine (AgSD) are proposed as an alternative to the occlusive AgSD-containing creams and gauzes, which are commonly used in the treatment of conventional burns. While the recognized cytotoxicity of AgSD has been reported to compromise its use as an antimicrobial drug in pharmaceuticals, this limitation can be overcome by developing sustained-release formulations. Microporous...
Physical-chemical analysis of colonial italian type salami commercialized in To...
Silva, Cristiana da; Savariz, Franciele Cristina; Follmann, Heveline dal Magro; Nuñes, Luciana; Chapla, Vanessa Mara; Silva, Classius Ferreira daItalian immigration in the west of Paraná State contributed for the development of small meat industries. The colonial Italian-type salami is one of the main commercialized meat products in this region, therefore making necessary its quality evaluation. The aim of this work is to verify whether the composition of the colonial salami is in accordance with Brazilian law, and the nutritional facts information on t...
Adsorption of textiles dyes in active carbon, seaweed and sawdust: determinatio...
Koroishi, Érika Tomie; Bonan, Andréia Aline; Andrade, Caroline Bonifácio de; Silva, Aracélis Ferreira da; Santos, Washington Luiz Felix dosTextile industries have environmental problems with their effluents due to high level of COD and color. Adsorption is one of the most important processes used to remove color from effluent. Adsorption isotherms of three adsorbing materials were determined: active carbon from the coconut bark, ground seaweed (a mixture mainly with Sargassum sp.) and sawdust (alternative material). Solutions with Red Remazol RG w...
