    摘要: A bone fusing implant device includes an elongated body extending along a longitudinal direction. The elongated body includes a first segment having an outer surface with cortical threads, a second segment having an outer surface with cancellous threads, a top segment and a bottom segment. The first segment is adjacent to the second segment along the longitudinal direction and is configured to engage a cortical bone with the cortical threads and the second segment is configured to engage a cancellous bone with the cancellous threads. The elongated body has one or more elongated fusing gutters extending along the longitudinal direction on an outer surface of the elongated body covering the first and second segments, a central opening extending along the longitudinal direction through the elongated body's center and one or more through-openings that extend horizontally and intersect with the one or more fusing gutters.

    摘要: A device and method are described for the naked eye visualization of fluorophores. The device has a light source capable of exciting fluorophores, a rack to receive one or more fluorophores and a window through which test tubes can be observed. The method provides a means for inferring the conformational state of molecules from the amount of fluorescence emitted by the fluorophores.

    摘要: The present invention relates to preparation of biodegradable microparticles formed from polylactide-polyglycolide copolymers (PLGA) polymer and how to achieve sigmoidal release of active pharmaceutical compound from the microparticles. In particular, the present invention relates to emulsification of an inner/oil phase to an outer/water phase followed by quenching and a single drying step for the preparation of microparticles having a preferred release profile of preferably basic/nucleophilic compounds such as risperidone. Alternatively the present invention is also suitable for hydrophobic compounds that have poor water-solubility and a high drug loading of >20% w/w is required. The release profile can be controlled by adjusting the degree of saturation of the outer/water phase with the organic solvent used in the inner/oil phase, the polymer concentration of the inner/oil phase and the temperature at the quenching step. In particular, an initial lag phase and a substantially sigmoidal release profile are achieved by using an outer aqueous phase over saturated with the solvent used in the inner phase at emulsification step, in combination with a low temperature during quenching.
