摘要:
The invention utilizes local search engines to view a display of local business listings in order of relevance to the user. Relevance to the user depends on a variety of factors whose importance varies by user and business—these factors include distance from user-defined starting location, business size, whether or not the business is local, content provided with listing, and relevance based on user-defined search terms. The system collects and parses business information from Web pages and other sources, stores the information in a format that facilitates searches, provides a simple way for users to initiate searches, analyzes all the factors mentioned above each time a search is performed, retrieves listings in order of factor importance, and displays results to the user in order and formatted to make further inspection and use of the results easy for the user.
摘要:
The present invention features a non-human animal model that is susceptible to infection by human hepatotrophic pathogens, particularly human hepatitis C virus (HCV). The model is based on a non-human, immunocompromised transgenic animal having a human-mouse chimeric liver, where the transgene provides for expression of a urokinase-type plasminogen activator in the liver. The invention also features methods for identifying candidate therapeutic agents, e.g., agents having antiviral activity against HCV infection. The animals of the invention are also useful in assessing toxicity of various agents, as well as the activity of agents in decreasing blood lipids.
