Abstract: The present invention provides novel methods for the treatment of retroviral infection, particularly HIV disease. According to the present invention, human HIV infected hosts were selected who had been on a stable dose of an anti-retroviral agent, such as zidovudine, for up to two years prior to administration of the ribosomal inhibiting protein trichosanthin, and who had failed anti-retroviral therapy, as manifest by decrease in CD4+ cells on at least two serial measurements, or loss of over 50 CD4+ cells/mm.sup.3 /year. These patients remained on the same dose of anti-retroviral agent (AZT or ddI) and received trichosanthin, 1.2 mg weekly, then monthly. A significant number of patients demonstrated improved CD4+ cell counts following administration of trichosanthin as compared to CD4+ cell counts prior to adminstration of the drug.

Abstract: Structures containing a dielectric material having a polymeric reactive ion etch barrier embedded therein. The preferred dielectric materials are polymers, preferably polyimide materials. The RIE etch barrier is a copolymer having an aromatic component having high thermal stability and having a cross-linking component selected from metallacyclobutane, metallabutene and vinyl groups. The etch barrier is deposited as a solvent free liquid which can fill gaps between the dielectric material and electrical conductors embedded therein. The liquid polymer is cured to a solid insoluble state. The structures with electrical conductors embedded therein are useful for electronic applications.

Abstract: The present invention provides a method for preparing aqueous formulations of thymopentin, which method permits the peptide to retain its biological activity during storage at room temperature.

Abstract: The present invention relates to novel LHRH analogs. The LHRH analogs include "pseudo" hexapeptide, heptapeptide, octapeptide and nonapeptide analogs of LHRH, wherein all or some of the amino acids, 1, 2 and 3 have been eliminated and the remaining (2-9), (2-10), (3-9), (3-10), (4-9) or (4-10) peptide is linked to various carboxylic acids which take the place of amino acids 1, 2 or 3 in LHRH.

Abstract: A process for removing toxins from solutions of proteins, in which an aqueous solution of a protein which contains a buffer substance, a chelating agent and a detergent is subjected to an ion exchange chromatography, is described.

Abstract: A method is provided for the treatment of grafts such as tissue or organs prior to transplantation into a suitable host. The grafts are incubated, coated, or perfused with TGF-.beta. for an effective time for the uptake of the agent into the grafts and induction of its biological effects. The thus-treated graft is then transplanted into a compatible host, preferably a human host.

Abstract: Bacteriocin compositions comprising lanthionine containing bacteriocins and non-bactericidal agents. When the bacteriocin compositions are combined with a suitable carrier with each component present in sufficient quantities such that the composition is effective against Gram negative bacteria in addition to Gram positive bacteria, they become enhanced, rapid acting, broad range bactericides suitable for a variety of applications.

Abstract: This invention relates to a method of isolating and purifying proteins such as fibroblast growth factor using metal chelate affinity column chromatography and without the use of heparin. Also disclosed is a method of recovering bFGF multimers and purifying bFGF using metal chelate affinity column chromatography in the absence of heparin.

Abstract: A magnetic storage medium is composed of a non-wettable substrate upon which a transient liquid metal layer is deposited and maintained as a distribution of discontinuous liquid features. A magnetic film layer is deposited on the transient liquid metal layer resulting in a reaction of the liquid metal with the magnetic film. The topology of the magnetic film is controllable by adjusting the thickness of the transient liquid metal layer.
