1. Titanium Coating with Hydroxyapatite and Chitosan Doped with Silver Nitrate
Biomaterials are effective alternatives for tissue substitution, including the bone tissue, since they do not pose risks of transmission of diseases or immune rejection. Nowadays, there is an interest in new materials capable of being associated with other substances which favor bone formation, especially natural biopolymers, in particular chitosan, which ma

2. Processamento e análise de imagens na caracterização da superfície do titânio submetido a um ensaio de cultura de células
This work aims to develop a methodology for analysis of images using overlapping, which assists in identification of microstructural features in areas of titanium, which may be associated with its biological response. That way, surfaces of titanium heat treated for 08 (eight) different ways have been subjected to a test culture of cells. It was a relationshi

3. Efeito do tratamento térmico do titânio sobre a proliferação de células pré-osteoblásticas
Titanium is a biomaterial widely employed in biomedical applications (implants, prostheses, valves, stents). Several heat treatments are usually used in order to obtain physical properties required to different applications. This work studied the influence of the heat treatment on microstructure of commercial pure titanium, and their consequences in growth a

4. A dosimetric approach for relating the biological response of the lung to the accumulation of inhaled mineral dust.
Results from studies of the retention of contrasting mineral dusts inhaled by rats (for periods of up to three months) and the resultant changes in the phagocyte defence system of the deep lung were examined. The dusts used were titanium dioxide (relatively innocuous) and quartz (relatively toxic). The parameters assessed included the accumulation of materia

5. Persistent biological reactivity of quartz in the lung: raised protease burden compared with a non-pathogenic mineral dust and microbial particles.
This study assessed the potential harmfulness of particles in the lung by measuring their ability to elicit and maintain an inflammatory response and to damage lung tissue. It compared the inflammogenicity of two nondurable, biological particulates (Corynebacterium parvum and zymosan) with a pathogenic mineral dust (quartz) and a nonpathogenic dust (titanium
