  • Patent number: 8334104
    Abstract: Methods and reagents are disclosed for pretreating a sample suspected of containing a hydrophobic drug for conducting an assay method for detecting the hydrophobic drug. A combination is provided in a medium that includes the sample, a releasing agent for releasing the hydrophobic drug and the metabolites from endogenous binding moieties, and a selective solubility agent that provides for substantially equal solubility of the hydrophobic drug and the metabolites in the medium. The selective solubility agent includes a water miscible, non-volatile organic solvent and is present in the medium in a concentration sufficient to provide for substantially equal solubility of the hydrophobic drug and the metabolites in the medium. The medium, which may further include a hemolytic agent, is incubated under conditions for releasing the hydrophobic drug and the metabolites from endogenous binding moieties. The pretreated sample may be subjected to an assay for determining the hydrophobic drug.

  • Patent number: 7650335
    Abstract: A method and system for allowing end users to create a database and a user interface to interact with database data are provided. The database management system provides a database abstraction layer that hides the complexities of a database and vendor-specific implementation details from the end user, while still allowing the end user to perform powerful database tasks. The database management system allows an end user with little or no knowledge about databases to create, edit, and maintain a database without understanding the details behind the database. The database management system also provides a facility for the easy creation of web pages to access the database to provide features such as searching, data entry, and browsing data stored in the database.

  • Patent number: 7555472
    Abstract: A method and system for augmenting a corpus with documents on concepts not sufficiently covered within the corpus is provided. The augmentation system generates a corpus concept graph from the documents of a corpus. A corpus concept graph represents concepts of the documents as nodes and related concepts as links between nodes. To generate a corpus concept graph, the augmentation system identifies the concepts that are related within each document of the corpus and adds nodes and links to the corpus concept graph for related concepts. The augmentation system analyzes the corpus concept graph to determine whether the relatedness of concepts of the documents of the corpus is sufficient. If the relatedness of a pair of concepts is not sufficient, then the augmentation system attempts to identify documents not already in the corpus that are related to the concepts that are not sufficiently related.

  • Publication number: 20060046290
    Abstract: In some embodiments, the present invention pertains to a method for conjugating a first compound to a second compound wherein the conjugation involves an electrophilic moiety. The method comprises reacting the first compound with the second compound to form a conjugate. The improvement in embodiments of the present invention comprises adding a nucleophilic reagent to the conjugate wherein the nucleophilic reagent forms a neutral product upon reaction with unreacted electrophilic moieties of the conjugate. In some embodiments, the nucleophilic reagent is substantially non-reactive with disulfide bonds in the event that the conjugate comprises disulfide bonds. The conjugate formed is doubly deactivated because the other moiety for linking to the electrophilic moiety is also deactivated.
