      Description

      This novel invention uses polishing techniques to slowly polish or abrade away stepped layers of an object to be scanned. The scanned object is cast into a contrasting resin which provides a dark (or light) background for photography. The layers are digitally photographed stepwise to produce a record of internal structures. 2D digital images are reassembled using computer and software methods to produce exquisitely fine detailed 3D digital models of the solid internal structures in full color.

      Because polishing can be controlled tightly, layers may be removed in the in the nanometer realm. This implies the limiting barrier in resolution is the pixel size of the recording camera. These cameras pixels are getting denser and denser as technology progresses which only improves the performance of the 3D scanner.

      The multi-spectral light used to illuminate the image plane can be used to identify the chemical components of the object. Therefore the 3D scanner has a spectrometer function as well.

      The Full Color 3D Solid Image Scanner would be important in the semiconductor industry. Most importantly 1st article scanning semiconductor devices to determine as manufactured state vs. as designed.

        Description

        An aliquot of serum was added to methanol. The mixture was vortex and centrifuged. The supernatant was transferred into clean tube with Al. The mixture was vortex. Then add H3PO4 and CCL3. After the mixture was vortexed and centrifuged for one minute at 2500 rpm, the chloroform extract was evaporated and the residue was redissolved methanol. Sample was injected into high performance liquid chromatography (HPLC).

      • Optimized Expression of IL-12 Cytokine FamilyOptimized Expression of IL-12 Cytokine Family

          Description

          The IL-12 family of cytokines (IL-12, IL-23, and IL-27) has an important role in inflammation and autoimmune diseases. IL-12 is produced by macrophages and dendritic cells in response to certain bacterial and parasitic infections and is a powerful inducer of IFN-gamma production. IL-23 is proposed to stimulate a subset of T cells to produce IL-17, which in turn induce the production of proinflammatory cytokines that lead to a protective response during infection. IL-27 appears to have duel functions as an initiator of TH1-type (cellular immunity) immune responses and as an attenuator of immune/inflammatory responses.

          The present inventions provide methods for improved expression of multimeric proteins by engineering different ratios of the subunit expression units in a cell or upon expression from a multi-promoter plasmid having different strength promoters. The inventors have improved the levels and efficiency of expression of the IL-12 family of cytokines, which includes IL-12, IL-23, and IL-27, by adjusting the transcription and translation of the alpha and beta subunits that comprise the heterodimeric proteins. Optimal ratios of expression for the two (2) subunits were determined for IL-12, IL-23, and IL-27.

            Description

            This additive makes conventional plastics biodegrade in landfills. It is cost competitive, any existing polymer factory can use it with no special equipment, versions are food contact compliant under FDA and EC regulations, and versions exist for all polymer families, including PLA (which despite its billing, doesn't biodegrade at all quickly in landfills.) See: http://earthnurture.com . I have recently filed a provisional patent, with non-publication requested, so either trade secret or patent protection is possible.
