  • Patent number: 6121341
    Abstract: An impoved barrier or drug delivery system which is highly adherent to the surface to which it is applied is disclosed, along with methods for making the barrier. In the preferred embodiment, tissue is stained with a photoinitiator, then the polymer solution or gel having added thereto a defined amount of the same or a different photoinitiator is applied to the tissue. On exposure to light, the resulting system polymerizes at the surface, giving excellent adherence, and also forms a gel in the rest of the applied volume. Thus a gel barrier of arbitrary thickness can be applied to a surface while maintaining high adherence at the interface. This process is referred to herein as "priming". the polymerizable barrier materials are highly useful for sealing tissue surfaces and junctions against leaks of fluids. In another embodiment, "priming" can be used to reliably adhere preformed barriers to tissue or other surfaces, or to adhere tissue surfaces to each other.

  • Patent number: 6119037
    Abstract: This invention relates to the field of medical devices employing electrophoresis to combat bacterial colonization. More particularly, it relates to an apparatus and method of providing an electrophoresis-type medical device that mitigates the burning of surrounding biological tissue. This invention uses grooves in the contact surface of the medical device for containing the electrodes which cause the electrophoresis to occur. The grooves allow the electrodes to contact biological fluid without contacting and hence burning the surrounding biological tissue. Through the use of this invention it is possible to provide an electrophoresis-type medical device while minimizing the burning of surrounding tissue.

  • Patent number: 6110744
    Abstract: The present invention provides viral vectors that have been engineered to contain a synthetic promoter that controls at least one essential gene. The synthetic promoter is induced by a specific gene product not normally produced in the cells in which the viral vector is to be transferred. The vectors are propagated in producer or helper cells that express the inducing factor, thereby permitting the virus to replicate to high titer. The lack of the inducing factor in the target cells precludes viral replication, however, meaning that no vector toxicity or immunogenicity arises. Where the virus carries a gene of interest, this should provide for higher level expression for longer periods of time than with current vectors. Methods for making the vectors, helper cells, and their use in protein production, vaccines and gene therapy are disclosed.

  • Patent number: 6110889
    Abstract: Disclosed are peptide-based compositions and methods for inhibiting and modulating the actions of CXC intercrine molecules. The antileukinate peptides described inhibit IL-8, GRO and MIP2.beta. binding to neutrophils and neutrophil activation. The peptides are particularly advantageous as they inhibit IL-8-induced enzyme release at a 25 fold lower concentration than is required to inhibit chemotaxis, which makes them ideal for treating various inflammatory diseases and disorders including, amongst others, Adult Respiratory Distress Syndrome (ARDS), cystic fibrosis and chronic bronchitis. The invention further includes methods for inhibiting tumor cell growth by employing selected members of the disclosed group of peptides to inhibit .alpha.-chemokine binding to the tumor cell.

  • Patent number: 6107457
    Abstract: Compositions comprising a mixture of peptides that bind to molecules involved in Bcr-Abl oncoprotein function are disclosed. In addition, expression of functional BCR protein (p160 BCR) or amino terminal fragments thereof (159, 221 and 413 amino terminal residues) by way of retrovirus vectors will oppose the biological function of Bcr-Abl (p160 BCR) or inactivate Bcr-Abl tyrosine kinase function or its signal transduction function. Bcr and Abl peptides, either tyrosine phosphorylated or unphosphorylated, that bind to a region near the amino terminus of Bcr to prevent formation of tetramer Bcr-Abl molecules, that bind to the SH2 domain of Grb2, to sites on tyrosine phosphorylated Shc protein, to sites of Crkl, and to an SH2 domain of Ras Gap comprise particular peptide preparations of the invention.

  • Patent number: 6095982
    Abstract: A method and apparatus for detecting tissue abnormality, particularly precancerous cervical tissue, through fluorescence or Raman spectroscopy, or a combination of fluorescence and Raman spectroscopy. In vivo fluorescence measurements were followed by in vitro NIR Raman measurements on human cervical biopsies. Fluorescence spectra collected at 337, 380 and 460 nm excitation were used to develop a diagnostic method to differentiate between normal and dysplastic tissues. Using a fluorescence diagnostic method, a sensitivity and specificity of 80% and 67% were observed for differentiating squamous intraepithelial lesions (SILs) from all other tissues. In accordance with another aspect of the invention, using Raman scattering peaks observed at selected wavenumbers, SILs were separated from other tissues with a sensitivity and specificity of 88% and 100%. In addition, inflammation and metaplasia samples are correctly separated from the SILs.

  • Patent number: 6096874
    Abstract: The synthesis of tamoxifen derivatives, most particularly halo, halo alkyl, hydroxy, and amino tamoxifen derivatives is disclosed. The native tamoxifen molecule includes a substituted chemical group positioned on the aliphatic chain of the tamoxifen molecule. Particular tamoxifen derivatives of the invention include chloro, bromo, iodo, fluoro, amino and DTPA tamoxifen derivatives, and corresponding lower alkyl halogenated forms. The halogenated tamoxifen derivatives possess superior binding affinities for estrogen receptor rich tissues, such as uterine tissue and breast tissue, relative to unsubstituted native tamoxifen. Radiolabeled forms of the tamoxifen derivatives may be used as highly specific imaging agents for estrogen receptor rich tissues. The fluoro and bromo tamoxifen derivatives are particularly useful for imaging estrogen receptors by PET whereas the iodinated tamoxifens are particularly useful in imaging estrogen receptors by SPECT.
