Abstract: A method by which consolidated articles can be produced from nanocrystalline materials to have mechanical properties that can be improved through thermal treatment. The method entails machining a body to produce polycrystalline chips having nanocrystalline microstructures, and then consolidating the chips to form a consolidated article having mechanical properties that exceed that of the body from which the chips were formed. In particular, consolidation of nanocrystalline chips formed by machining a supersaturated solid-solution body causes precipitation of a fine dispersion of precipitates in the consolidated article, with the potential for certain properties to even improve during consolidation or subsequent thermal treatment of the consolidated article.

Abstract: The present invention provides processes for the production of paclitaxel. Paclitaxel is produced by protecting the C(7) and the C(10) hydroxy groups of 10-DAB with a bridging silicon-based protecting group. The resulting 7,10-protected 10-DAB derivative is then derivatized and deprotected to form paclitaxel.

Abstract: Pyrogenic toxins, such as staphylococcal enterotoxins, modified in the disulfide loop region are provided. The modified toxins retain useful biological properties but have substantially reduced toxicity compared to the corresponding unmodified native toxin. The native pyrogenic toxins are typically modified by deletions within the disulfide loop region to produce modified enterotoxins having 100-fold or greater decrease in toxicity.

Abstract: A three-dimensional projection reconstruction pulse sequence acquires two half echoes in a steady state free precession (SSFP) scan. A method for combining the two echoes to suppress either fat or water in the reconstructed image is described includes shifting the phase of one echo and combining them in a regridding process used to transform the radial data to a Cartesian grid prior to image reconstruction.

Abstract: A system and method for detecting mass based on a frequency differential of a resonating micromachined structure, such as a cantilever beam. A high aspect ratio cantilever beam is coated with an immobilized binding partner that couples to a predetermined cell or molecule. A first resonant frequency is determined for the cantilever having the immobilized binding partner. Upon exposure of the cantilever to a solution that binds with the binding partner, the mass of the cantilever beam increases. A second resonant frequency is determined and the differential resonant frequency provides the basis for detecting the target cell or molecule. The cantilever may be driven externally or by ambient noise. The frequency response of the beam can be determined optically using reflected light and two photodetectors or by interference using a single photodetector.

Abstract: The present invention is directed to non-pathogenic, oncolytic, recombinant polioviruses for the treatment of various forms of malignant tumors. The recombinant polioviruses of the invention are those in which the internal ribosomal entry site (IRES) of the wild type poliovirus was exchanged with the IRES of other picornaviruses, and optionally P1, P3 or the 3?NTR thereof was exchanged with that of poliovirus Sabin type. More particularly, the present invention is directed to the administration of the non-pathogenic, oncolytic, recombinant poliovirus to the tumor directly, intrathecally or intravenously to cause tumor necrosis. The method of the present invention is particularly useful for the treatment of malignant tumors in various organs, such as: breast, colon, bronchial passage, epithelial lining of the gastrointestinal, upper respiratory and genito-urinary tracts, liver, prostate and the brain.

Abstract: A system and method for generating a three-dimensional visualization image of an object such as an organ using volume visualization techniques and exploring the image using a guided navigation system which allows the operator to travel along a flight path and to adjust the view to a particular portion of the image of interest in order, for example, to identify polyps, cysts or other abnormal features in the visualized organ. An electronic biopsy can also be performed on an identified growth or mass in the visualized object. Virtual colonoscopy can be enhanced by electronically removing residual stool, fluid and non-colonic tissue from the image of the colon, by employing bowel preparation followed by image segmentation operations. Methods are also employed for virtually expanding regions of colon collapse using image segmentation results.

Abstract: Each frame of time-series pictures shot by a camera is converted to a spatial differential frame picture by the following equations: H(i,j)=?|G(i+di,j+dj)?G(i,j)|/(Gi,j,max/Gmax), I=Gmax/{1+exp(?0.02(H?80))}, where ? denotes a sum over di=?1 to 1 and dj=?1 to 1, Gi,j,max denotes the maximum pixel value of 3×3 pixels having its center at the i-th row and j-th column, and Gmax denotes the assumable maximum value 255 of the pixel value G(i, j). Moving objects at a time t is discriminated based on a correlation between spatial differential frame pictures at times (t?1) and t and a discrimination result of moving objects included in the spatial differential frame picture at the time (t?1).
