摘要:
An integrated retrieval scheme retrieves data involved in a plurality of semi-structured documents scattering over open networks and collects the required information item by item from the semi-structured documents through a unified interface without regard to differences in the document structures, presentation styles, and elements of the semi-structured documents. The search scheme receives a query consisting of search items and search conditions from a user. The search scheme finds, according to location data that specifies the location of each of the semi-structured documents, the location of each semi-structured document that contains all search items and converts, if necessary, item presentation styles of the entered query into that of the location found semi-structured documents according to style conversion data, and forms queries for the location found semi-structured documents, and transmits the queries to the found locations and obtains the location found semi-structured documents, and extracts item data from the obtained semi-structured documents according to structure data being used to delimit document into items and attribute data being used for conditional retrieval, and prepares a search result, and converts, if necessary, item presentation styles of the search result into the item presentation styles of each user according to the style conversion data.

摘要:
A novel antibiotic complex designated BU-4224V produced by fermentation of Kibdelosporangium albatum sp. nov. Strain R761-7. The complex may be separated chromatographically into bioactive components designated BU-4224V A, B.sub.1, B.sub.2, and C. The components BU-4224V B.sub.1 and B.sub.2 display both antiviral and antimicrobial activity, while component BU-4224V A has antimicrobial activity and component BU-4224V C has antiviral activity.
摘要:
Production of an antiviral antibiotic complex, BU-3889V and its bioactive components A.sub.1, A.sub.2, A.sub.3, D.sub.1, D.sub.2 and D.sub.3, by fermentation of a BU-3889V producing strain of the new microorganism Amycolatopsis orientalis ATCC-53884 is disclosed. Complex BU-3889V is recovered and the components separated by the use of ion exchange chromatography techniques. The bioactive components are characterized by their physico-chemical characterizing properties. The products have been found to be effective to inhibit viruses including herpes simplex virus, human immunodeficiency virus (HIV) and influenza virus.

摘要:
A new antitumor antibiotic designated herein as BMY-28121 is produced by fermentation of Streptomyces albus strain K7331-113 (ATCC 39897). BMY-28121, which may be recovered from the fermentation broth in either its natural free hydroxy form (BMY-28121A) or methyl ether form (BMY-28121B), inhibits gram-positive bacteria and anaerobes and inhibits the growth of mammalian tumors such as P-388 leukemia, L-1210 leukemia and B16 melanoma.
