13. Improved biological performance of magnesium by micro-arc oxidation
Magnesium and its alloys have recently been used in the development of lightweight, biodegradable implant materials. However, the corrosion properties of magnesium limit its clinical application. The purpose of this study was to comprehensively evaluate the degradation behavior and biomechanical properties of magnesium materials treated with micro-arc oxidat

14. Surface characterization and osteoblast-like Cells culture on collagen modified PLDLA scaffolds
Surface modification techniques based on the grafting of chemical functional groups and immobilization of bioactive molecules have been used to improve biocompatibility and clinical performance of bioabsorbable scaffolds in tissue engineering and medicine regenerative applications. This study aimed at developing and characterizing a biomimetic surface to sti

15. Citocompatibilidade de discos de titânio tratados com cobertura usando nanotecnologia de prata / Cytocompatibility of titanium disks treated using silver nanotechnology
Os componentes protéticos que fazem a união entre implante e prótese são importantes para a manutenção da saúde peri-implantar sendo responsáveis pela vedação permucosa e impedindo a penetração de agentes químicos ou bacterianos desencadeadores de processos destrutivos nas estruturas ao redor do implante. Assim faz-se importante o desenvolviment

16. Incorporation of strontium up to 5 Mol. (%) to hydroxyapatite did not affect its cytocompatibility
The aim of this work was to produce hydroxyapatite (HA) granules containing 0, 0.5, 1 and 5 mol. (%) of strontium (Sr), evaluate the physico-chemical properties and also the cytotoxicity by three different parameters of cell viability (ISO 10993-5, 10993-12). The physico-chemical characterization was carried out by using X-ray diffraction (XRD), Fourier-tran

17. Cytocompatibility of chitosan and collagen-chitosan scaffolds for tissue engineering
In this work, chitosan and collagen-chitosan porous scaffolds were produced by the freeze drying method and characterized as potential skin substitutes. Their beneficial effects on soft tissues justify the choice of both collagen and chitosan. Samples were characterized using scanning electron microscope, Fourier Transform InfraRed Spectroscopy (FTIR) and th

18. In vitro studies of multiwalled carbon nanotube/ultrahigh molecular weight polyethylene nanocomposites with osteoblast-like MG63 cells
Carbon nanotubes are highly versatile materials; new applications using them are continuously being developed. Special attention is being dedicated to the possible use of multiwalled carbon nanotubes in biomaterials contacting with bone. However, carbon nanotubes are also controversial in regards to effects exerted on living organisms. Carbon nanotubes can b

19. Characterization and in vitro cytocompatibility of an acid-etched titanium surface
O objetivo deste estudo foi caracterizar a microestrutura de uma superfície de titânio comercialmente puro (cpTi) condicionada com HCl/H2SO4 (acid etched) (AE-cpTi) e investigar sua citocompatibilidade in vitro, comparada à do cpTi usinado (turned) (T-cpTi). O T-cpTi apresentou uma superfície com sulcos e o AE-cpTi exibiu uma superfície caracterizada pe

20. Cell adhesion on different titanium-coated surfaces
Titanium (Ti) is a biocompatible material, and calcium phosphate coating on titanium is commonly applied in order to obtain faster osseointegration around metallic implant. Osteoblast adhesion on three different Ti surfaces was evaluated. The investigated surfaces were commercially pure Ti (cp Ti), Ti coated with sodium titanate (Na-Ti), and Na-Ti followed b

21. Evaluation of the cytocompatibility of mixed bovine bone
O tratamento do osso bovino com peróxidos e agentes caotrópicos visa à obtenção de uma matriz óssea acelular, com manutenção do complexo colágeno-apatita e maior resistência mecânica, denominada osso bovino misto (OBM). O objetivo desse estudo foi avaliar a citocompatitiblidade do osso bovino misto e a interação célula-OBM. Células Balb-c 3T3

22. Estudo in vitro da compatibilidade do osso bovino misto quimicamente tratado
Biomaterials have been developed and investigated aiming to help bone regeneration. Xenografts of bovine origin stand out due to their biocompatibility, low cost and availability. Some protocols have been tested to develop a chemically treated material containing the anorganic (hydroxiapatite) and the organic (collagen) components of bovine boned: the mixed

23. Novel Biodegradable Polyester Poly(Propylene Succinate): Synthesis and Application in the Preparation of Solid Dispersions and Nanoparticles of a Water-Soluble Drug
Poly(propylene succinate) (PPSu) polymers of average molecular weights from 2,800 to 13,100 g/mol were synthesized and characterized with regard to crystallinity, thermal properties, and cytocompatibility. Higher molecular weight samples exhibited lower degree of crystallinity and melted at lower temperatures. Melting of the polymer appeared to begin at 38�
