      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.

              Description

              This design is a major change in fire fighting ladder truck design.
              The design allows the fire fighter to ride up the ladder, saving energy. It also allows the fire fighter to send incapacitated people down the ladder alone, allowing the fire fighter to continue his/her work. This design also allows extra supplies/equipment to be sent up or down without a human being put in further danger.
              The automation for this design is critical. The ladder framework will be re-designed to deal with the special ladder.
              This design allows the ladder truck to do things a 'cherry picker' type cannot do, or cannot do without serious uses of energy and manpower.
