  • Publication number: 20240299333
    Abstract: A ((((1r,3R,5S,7r)-3,5-dimethyladamantan-1-yl)carbamoyl)oxy)-methyl benzoate injection preparation contains ((((1r,3R,5S,7r)-3,5-dimethyladamantan-1-yl)carbamoyl)oxy)-methyl benzoate, a suspension agent, a stabilizer, an osmotic pressure adjustment agent, a pH regulator and a solvent; and the preparation may be a ready-to-use liquid injection and may also be a lyophilized powder for injection. The preparation has noticeable slow-release effects after injection, so that the drug action time can be prolonged, the frequency of dose can be reduced, the compliance of patients can be enhanced, and bioavailability can be increased. A method for preparing the above-mentioned ((((1r,3R,5S,7r)-3,5-dimethyladamantan-1-yl)carbamoyl)oxy)-methyl benzoate injection preparation is simple, economical and suitable for industrial production.

  • Publication number: 20240277495
    Abstract: The present invention provides a stent and a drug-loaded stent. The stent includes at least one stent mesh, wherein each stent mesh comprises a plurality of stent struts sequentially connected circumferentially around the stent mesh, wherein the plurality of the stent struts are sequentially connected end to end, and a joint is formed at the connected ends of adjacent stent struts. The stent mesh is configured to expand or collapse as a result of widening or narrowing of angles at the joints. Each stent strut includes at least one main section and at least one broadened section. The main section has a width smaller than that of the broadened section. In each stent mesh, the broadened sections of adjacent stent struts are staggered along an axis of the stent mesh. The drug-loaded stent is of a similar structure.

The stent mesh is configured to expand or collapse as a result of widening or narrowing of angles at the joints. Each stent strut includes at least one main section and at least one broadened section. The main section has a width smaller than that of the broadened section. In each stent mesh, the broadened sections of adjacent stent struts are staggered along an axis of the stent mesh. This arrangement enables reasonable space utilization and achieves a good tradeoff between metal coverage and radial strength of the stent.

Each stent strut includes at least one main section and at least one broadened section. The main section has a width smaller than that of the broadened section. In each stent mesh, the broadened sections of adjacent stent struts are staggered along an axis of the stent mesh. The different widths of the broadened sections and the main sections, as well as the staggered arrangement of the broadened sections, enable reasonable space utilization and achieve a good tradeoff between metal coverage and radial strength of the stent.

  • Publication number: 20100254566
    Abstract: A data set is transformed to a domain in which values are robust to distortion. The values are then expanded to carry auxiliary data. To recover the data, the data set is transformed into the domain, further transformed to get a set of possibly expanded data, and then processed to extract auxiliary data from the expanded values.
