Background: Drug resistance is a primary hindrance for the efficiency of chemotherapy against osteosarcoma. Although chemotherapy has improved the prognosis of osteosarcoma patients dramatically after introduction of neo-adjuvant therapy in the early 1980's, the outcome has since reached plateau at approximately 70% for 5 year survival. The remaining 30% of the patients eventually develop resistance to multiple types of chemotherapy. In order to overcome both the dose-limiting side effects of conventional chemotherapeutic agents and the therapeutic failure incurred from multidrug resistant (MDR) tumor cells, we explored the possibility of loading doxorubicin onto biocompatible, lipid-modified dextran-based polymeric nanoparticles and evaluated the …

The use of biomolecular motors for nanotechnological applications has been impaired by an inability to control biomolecular motor activity in a temporal fashion. Previous data has suggested that myosin activity can be modulated by inducing changes in the degree of myosin oxidation. The hypothesis of this study is that myosin motor activity can be regulated by altering the amount of antioxidants and reducing agents present in assay solution. To test this hypothesis we systematically altered the concentration of reducing agents and examined the effects of these changes on myosin-dependent actin filament translation. Our findings indicate that myosin activity can be …

The current rise in the interest in physical phenomena at nano spatial scale is described hereby as a natural consequence of the scientific progress in manipulation with matter with an ever higher sensitivity. The reason behind arising of the entirely new field of nanoscience is that the properties of nanostructured materials may significantly differ from their bulk counterparts and cannot be predicted by extrapolations of the size-dependent properties displayed by materials composed of microsized particles. It is also argued that although a material can comprise critical boundaries at the nano scale, this does not mean that it will inevitably exhibit …
