Abstract:
Compositions for the inhibition of HIV-1 comprising the use of polyamide nucleic acids (PNAs) that bind to either the transactivation response element or primer binding sequence of the HIV virus are taught. The PNAs may be bound to a membrane transducing peptide, such as transportan. The methods for treating patients infected with HIV or for protecting non-infected patients against HIV infection using the anti-HIV compositions are also taught.
Abstract:
This invention claims the process for producing two structural variants of functionalized 4-amino-3-mercapto-1,2,4-triazoles as inhibitors of nitric oxide synthase (NOS) and as inhibitors of malignant cell growth. This fundamental molecular construct operates as a heterocyclic mimic of the open-chain N-aminoarginines (or N-aminoguanidines) previously established as NOS inhibitors.
Abstract:
The present invention is directed to an apparatus for and method of treatment or vascular procedures. An exitable lumen guide wire sheath (3) is disclosed and advantages thereof. The exitable lumen guide wire sheath (3) and method may be used as a multiple exitable lumen or single exitable lumen. A method of treatment of multiple branch vascular lesions is disclosed in which a desired branch of a multiple branch lesion may be protected for further procedures by an interventionalist or other practitioner. Other combinations and uses for the disclosed invention will be apparent to those skilled in the art.
Abstract:
Topors and topors antibody can be used to manipulate the presence and function of both Top1 and p53 in cells, thus controlling the function of the Top1 and p53 proteins. Topors is implicated in prevention of tumorigenesis through its role in DNA repair and preventing faulty or mutated DNA from replicating. Topors can be used therapeutically as a medicament and topors DNA can be used in gene therapy. Topors antibody may be used to detect the presence of cancer by screening for the absence of topors in a given cell or tissue sample. Kits comprising the topors antibody are also contemplated.
Abstract:
The invention relates to compositions and methods for enhancing bone healing, bone formation and wound healing. More specifically, it relates to the use of cyclooxygenase 2 (COX-2) following bone fracture, orthopaedic procedure or wound infliction to enhance healing.

Abstract:
Methods of inducing differentiation of mammalian bone marrow stromal cells into cells of multiple embryonic lineages by contacting marrow stromal cells with precursor differentiation-inducing compounds followed by contacting the partially differentiated precursor cells with specific cell type differentiation-inducing compounds. In one embodiment, the MSC derived precursor cell cultures comprise cells, at least some of which simultaneously express markers that are characteristic of endodermal and ectodermal cell types. In another embodiment, the differentiated cells are insulin-secreting pancreatic islet cells. Precursor differentiation-inducing compounds of the invention include anti-oxidants such as, but not limited to, beta-mercaptoethanol, dimethylsulfoxide, butylated hydroxyanisole, butylated hydroxytoluene, ascorbic acid, dimethylfumarate, and n-acetylcysteine. Endodermal cell differentiation-inducing compounds of the invention inclue but are not limited to anti-oxidants and growth factors including basic fibroblast growth factor. Once induced to differentiate into a particular cell type, the cells can be used for cell therapy, gene therapy, or both, for treatment of diseases, disorders, or conditions associated with tissues of multiple embryonic origins.
Abstract:
This invention relates to anti-viral agents that target RNase H substrates of reverse transcriptase and methods of using these agents to inhibit reverse transcriptase and viral replication. The invention also relates to methods for screening anti-viral agents capable of inhibiting the RNase activity of reverse transcriptase by targeting RNA-DNA hybrid substrates.

Abstract:
Site-specific modified proteins and method for producing site-specific modified proteins using amino acid analogs are disclosed. Methods for labeling proteins at a desired site in the presence of nucleophilic side chains, including lysine and cysteine side chains, are also disclosed. Methods for labeling the site-specific modified proteins are also disclosed.
