Background
Many (artificial) bone substitute materials are currently available for use in orthopaedic trauma surgery. Objective data on their biological and biomechanical characteristics, which determine their clinical application, is mostly lacking. The aim of this study was to investigate structural and in vitro mechanical properties of nine bone substitute cements registered for use in orthopaedic trauma surgery in the Netherlands. 相似文献993.

The 16 priority PAH were determined in sediment samples from the insular zone of Guajará Bay and Guamá River (Southern Amazon River mouth). Low hydrocarbon levels were observed and naphthalene was the most representative PAH. The low molecular weight PAH represented 51% of the total PAH. Statistical analysis showed that the sampling sites are not significantly different. Source analysis by PAH ratios and principal component analysis revealed that PAH are primary from a few rate of fossil fuel combustion, mainly related to the local small community activity. All samples presented no biological stress or damage potencial according to the sediment quality guidelines. This study discuss baselines for PAH in surface sediments from Amazonic aquatic systems based on source determination by PAH ratios and principal component analysis, sediment quality guidelines and through comparison with previous studies data. 相似文献

The antiproliferative effects of twenty-eight tetrasubstituted olefins bearing a ferrocenyl group, including six never-reported compounds, were evaluated against SF-295 (human glioblastoma), HCT-8 (human colon cancer), MDA-MB-435 (human melanoma) and HL-60 (human promyelocytic leukemia) using the MTT test. IC50 values were determined for twenty-three active compounds and of these, ten compounds had IC50 values lower than 2 μM on one or more cell lines. Of all the compounds, only two produced significant amounts of ROS on HL-60 cells, and ROS production and growth inhibition could not be correlated. The ten most antiproliferative compounds were tested for their hemolytic activity on mouse erythrocytes. Five compounds showing high antiproliferative activity and low hemolytic activity were thus identified for further study. 相似文献
