4. On the Use of a TiO2 Sol-Gel for Horseradish Peroxidase Enzyme Immobilization for Development of an Amperometric Biosensor
The sol-gel technique has drawn considerable attention in the area of biomolecules immobilization by virtue of its intrinsic properties including chemical inertness, thermal stability, and good biocompatibility. The present work reports the development of a bio-sensing methodology which involves the immobilization of horseradish peroxidase enzyme (HRP) on pe

5. EFEITO DO TEOR DE GLICEROL NO TRANSPORTE DE VAPOR D’ÁGUA ATRAVÉS DE FILMES DE TRIACETATO DE CELULOSE PRODUZIDOS A PARTIR DO APROVEITAMENTO DA PALHA DE MILHO (ZEA MAYS L.)
Glycerol is a plasticizer widely used due to its good plasticization efficiency, great availability, biocompatibility and low exudation. It is a renewable raw material that, when introduced in biodegradable films, promotes significant changes in its properties and, thus, guarantees a wide spectrum of application. In this work, corn straw was used to produce

6. ASPECTOS ESTRUTURAIS DE ESFERAS DE QUITOSANA/PVA RETICULADAS COM GLUTARALDEÍDO SUBMETIDAS A DIFERENTES TRATAMENTOS TÉRMICOS
Chitosan is a biopolymer derived from chitin and the most abundant polysaccharide in nature after cellulose. This biopolymer has been applied in different areas due its biodegradability and biocompatibility properties. Modifications of chitosan structure by cross-linking chemical agents can alter its physical, chemical, and morphological characteristics. The

7. BINARY MICELLES (E45S8/F127) FOR QUERCETIN AND GRISEOFULVIN SOLUBILISATION
Micelles have aroused interest due to their ability to assist in the transport of poorly soluble drugs. In this study the mixture of copolymers F127/E45S8 in different proportions (F/ES 30/70, 50/50 and 70/30) was performed to improve the bioavailability of griseofulvin and quercetin. The results of cytotoxicity (MTT assay) revealed that the copolymers F127

9. Comparison of subcutaneous inflammatory response to commercial and engineered zinc hydroxyapatite implants in rabbits
RESUMO A hidroxiapatita (HA) é amplamente utilizada como biomaterial para reparo ósseo e revestimento de próteses metálicas. As principais limitações dos atuais compostos comerciais de hidroxiapatita sintética incluem alto custo e menor disponibilidade, especialmente para fins de medicina veterinária. Além disso, acredita-se que a biocompatibilidade

10. Bubaline Diaphragm Matrix: Development and Clinical Assessment into Cattle Abdominal Hernia Repair
Abstract The purpose of the study was to develop a xenogenic bubaline diaphragm matrix (BDM) for abdominal hernia repair. A fresh diaphragm was decellularized using aqueous sodium dodecyl sulfate (SDS) solutions (0.5-4% w/v) over a period. Acellularity was confirmed histologically and characterized by Masson’s trichrome staining, scanning electron microsc

11. In vitro Evaluation of PHBV/PCL Blends for Bone Tissue Engineering
The objective of this study was to evaluate Vero cells in in vitro biocompatibility tests with pure PHBV and PCL and 75/25 and 50/50 blends developed for bone tissue bioengineering in dense or porous forms. The biomaterials were characterized morphologically by scanning electron microscopy, (SEM) stereoscopic imaging (SI), and micrometer measurement. Cellula
