Abstract: It has been determined that a specific metaplastic lineage that contains immunoreactivity for a trefoil polypeptide, spasmolytic peptide, is associated with and gives rise to the vast majority of human adenocarcinomas. The identification of this Spasmolytic Polypeptide Expressing Metaplasia (SPEM) is a major factor for grading of biopsies of the stomach to assess risk for gastric cancer. It also forms the basis of a method for serological screening for those at risk for gastric cancer. In a preferred embodiment, antibodies to spasmolytic peptide (hSP) are used in immunostaining of biopsies of gastric tissue obtained by endoscopy for grading biopsies. Those patients having these cells, characterized by a morphology more typical of a type of cell present normally in the intestine and not stomach, Brunner's gland cells, are at risk of developing adenocarcinoma.

Abstract: A method for beneficially restructuring ingestible substances such as sports drinks, water, neutraceuticals, pharmaceuticals, and the like and its contents for consumption by organisms. The method is also applied to topical substances such as lotions and creams. The method involves subjecting such substances for a period of time to an electromagnetic field of a specified flux density varying from 10−5 to 10−21 gauss and a specific frequency varying from 0 hertz to 300 hertz, depending on the intended subsequent use of the substance. The specific flux density and the specific frequency is empirically determined to restructure the substances such that the substances beneficially affect the organism which has the substances incorporated into the organism's metabolism.

Abstract: A novel method of hematoma-directed ultrasound guided excisional breast biopsy is disclosed. In one aspect of the inventon, the hematoma is produced by an injection of the patient's own blood into a pre-selected area to target a lesion. Detection of the targeted lesion and hematoma is achieved with MRI. In a second aspect of the invention, the hematoma is produced by stereotactic core needle breast biopsy in a pre-selected area, and the targeted lesion and hematoma are detected using intraoperative ultrasound. The method avoids many of the disadvantages associated with traditional needle localized breast biopsy. The method can also be used to guide the excision of lesions visualized by MRI, ultrasound, mammography, PET scanning, and scintimammography. The method may be used in any organ and, in particular, the breast.

Abstract: The invention relates to detection of MAP-2 (microtubule associated protein-2) as a marker to determine the metastatic potential of a tumor, including tumors derived from the neural crest such as melanomas, gliomas, Schwanomas, chromocytomas and small cell lung cancer. In one aspect, the invention comprises a method for determining the metastatic potential of a tumor sample, wherein decreased levels of MAP-2 expression in a test sample relative to controls indicates that the sample has increased metastatic potential as compared to the control. In another aspect, the invention comprises a method to prevent tumor progression in metastatic melanoma by increasing levels of MAP-2 protein in cells.

The invention is comprised of two major pieces: a chamber within which the AFM scanning head assembly is placed, and an integrated sample platform and spring-loaded base-plate that allows samples to be loaded and unloaded without removal of the chamber from the AFM scanning head assembly. The sample platform, which extends up from the base-plate and is inserted into the chamber, can include a magnet that is securely attached to the base.

Abstract: A number of cDNA clones whose products may interact with D1 receptors in vivo were identified. One of the clones, P24, was characterized further. P24 is localized in dendrites and spines of pyramidal cells in PFC. The extent of overlap between P24 expressing and D1 receptor expressing pyramidal cells appeared to be 100%. In contrast, only a limited number D1 receptor antibody labeled neurons in caudate expressed P24. P24 lowers the threshold of D1 receptor response to dopamine (DA) by an order of magnitude. Sequence similarity suggests P24 is a diverged member of the RAMP family. The P24 protein is therefore referred to as a D1 DA RAMP, calcyon. The isolated protein and nucleotide molecule encoding the protein, as well as primers for the nucleotide, are described. The protein and compounds modifying DA binding to the receptor or calcium release which is mediated by the Calcyon, are useful in research studies, drug screening, and therapeutically.

Abstract: Disclosed are oligomers that bind Ku protein. These oligomers are useful for inhibiting activation of DNA-PK, treating certain forms of autoimmune disease, detection and purification of Ku protein, and identification of proteins that interact with Ku protein. Preferably, the oligomers are composed of nucleotides, nucleotide analogs, or a combination. Most preferably, the oligomers are composed of ribonucleotides. Also disclosed is a method of inhibiting DNA repair, a method of identifying cellular proteins that interact with Ku protein, and a method of treating autoimmune disease in patients with anti-Ku antibodies. The disclosed oligomers can have several preferred features, either alone or in combination, in addition to Ku binding. One such feature, referred to herein as inhibition activity, is inhibition of DNA-PK kinase activity. Another preferred feature, referred to herein as aptamer motifs, is the presence of one or more of the base sequences GCUUUCCCANNNAC, A(A/C)AUGA, and AACUUCGA.

Abstract: The examples demonstrate that GIP receptor mRNA and protein are present in normal bone and osteoblastic-like cell lines, and that high-affinity receptors for GIP can be demonstrated by 125I GIP binding studies. When applied to osteoblast-like cells (SaOS2), GIP stimulated an increase in cellular cAMP content and in intracellular calcium, with both responses being dose dependent. Moreover, administration of GIP results in elevated expression of collagen type I mRNA as well as an increase in alkaline phosphatase activity. Both of these effects reflect anabolic actions of presumptive osteoblasts. These results provide the first evidence that GIP receptors are present in bone and osteoblastic like cells and that GIP modulates the function of these cells. GIP has anabolic actions on remodeling bone, increasing vertebral bone density in a rat model of osteoporosis. GIP at 10 nM inhibits PTH-induced bone resorption in a fetal long bone assay and stimulates the synthesis of type 1 collagen mRNA.
