摘要:
Attenuated recombinant viruses containing DNA encoding an immunodeficiency virus and/or CTL antigen, as well as methods and compositions employing the viruses, expression products therefrom, and antibodies generated from the viruses or expression products, are disclosed and claimed. The recombinant viruses can be NYVAC or ALVAC recombinant viruses. The DNA can code for at least one of: HIV1gag(+pro)(IIIB), gp120(MN)(+transmembrane), nef(BRU)CTL, pol(IIIB)CTL, ELDKWA or LDKW epitopes, preferably HIV1gag(+pro)(IIIB), gp120(MN) (+transmembrane), two (2) nef(BRU)CTL and three (3) pol(IIIB)CTL etpitopes; or two ELDKWA in gp120 V3 or another region or in gp160. The two (2) nef(BRU)CTL and three (3) pol(IIIB)CTL epitopes are preferably CTL1, CTL2, pol1, pol2 and pol3. The recombinant viruses and gene products therefrom and antibodies generated by the viruses and gene products have several preventive, therapeutic and diagnostic uses. DNA from the recombinant viruses are useful as probes or, for generating PCR primers or for immunization. Also disclosed and claimed are HIV immunogens and modified gp160 and gp120.

摘要:
A complete genomic clone of HIV-2 designated HIV-2.sub.SBL/ISY was cloned from DNA of the neoplastic human cell line HUT78 infected with the HIV-2.sub.SBL6669 viral isolate. The clone was sequenced and the sequence compared with those of known HIV-2 isolates. The invention is advantageous for it provides an animal model for the study of HIV infection in man.
摘要:
A document navigation tool that automatically navigates a document based on previous input from the user. The document navigation tool is utilized each time a page loads. The method recognizes user behavior on pages using patterns, which are based on four criterion: location, frequency, consistency, and scope. If the user has visited the page previously and has established a pattern, the method automatically focuses on the portion of the page indicated by the pattern, e.g. the location on a web page of the link clicked by the user in the user's last three visits to the page. If the user has not visited the page previously, the method logs the events that occur during this visit to the page.
摘要:
A screen reader application for visually impaired users suppresses unwanted content that is output by Braille or text-to-speech. The invention accesses, but does not modify, the document object model of the web page and enumerates web page elements for the end user to either hide or skip to. The end user selections are saved as rules which may be applied according to various levels of scope include web page specific, site specific or web-wide. A screen magnification application for visually impaired users automatically sets the visual focus and magnification level on a web page element according to end-user selection.
摘要:
A method for inhibiting replication of reverse transcriptase dependent virus in plant or animal cells, comprising the step of administering to said cells a compound that depletes the intracellular pool of deoxyribonucleoside phosphate in an amount effective to inhibit replication of said virus. Hydroxyurea is one such suitable compound. Also disclosed is a method for producing incomplete reverse-transcriptase dependent viral DNA, by administering a deoxyribonucleoside phosphate-depleting drug to cells infected with such a virus.
