Abstract: The present invention provides a dispersant for aqueous and non-aqueous systems which can disperse insoluble fine powders in non-aqueous liquids in a short period of time and give long-term dispersion stability to the resulting dispersions without allowing the formation of hard cake or precipitates. The dispersant is a compound of the formula wherein SO is styrene oxide; R is a C8–C22 saturated or unsaturated group; x=1–100; y=1–3; z=1–100 and s=1–100. The dispersant of the invention is also particularly effective for dispersing additives into polymers such as polyesters, polyamides, polycarbonates, polyethylene and polypropylene.

Abstract: A mixed hydrogen-oxygen fuel generator system uses an electrolytic solution to generate gaseous hydrogen-oxygen fuel through the electrolysis of water. This generator system includes: at least one electrolytic cell with multiple metallic plates used as an internal isolation system in which two of the plates separately connect to both the positive and negative terminal of a DC circuit. These plates are used for the electrolysis of the electrolytic solution in the cell(s) to produce, under pressure, mixed hydrogen-oxygen fuel. The apparatus also includes a cooling system containing a water cooling tank in which there are two zones: one is the electrolytic solution circulation coil and the another is a water circulation zone.

Abstract: The instant invention provides a method of treating or preventing osteoarthritis, joint effusion, joint inflammation and pain, synovitis, lameness, post operative arthroscopic surgery, deterioration of proper joint function including joint mobility, the reduction or inhibition of metabolic activity of chondrocytes, the activity of enzymes that degrade cartilage, the reduction or inhibition of the production of Hyaluronic acid, said method comprising orally administering to a mammalian species a therapeutically effective amount of Hyaluronic Acid or pharmaceutically acceptable salts thereof. Additionally, compositions containing hyaluronic acid; chondroitin sulfate, and glucosamine sulfate in a paste formulation are also disclosed which can be administered on their own or can be used as a feed additive.
Abstract: The present invention describes a rapid and efficient in vivo library-versus-library screening strategy for identifying optimally interacting pairs of heterodimerizing polypeptides. It allows for the screening of a protein library against a second protein library, rather than against a single bait protein, and thus has numerous applications in the study of protein-protein interactions. Additionally, it allows for the application of different selection stringencies. Two leucine zipper libraries, semi-randomized at the positions adjacent to the hydrophobic core, were genetically fused to either one of two designed fragments of the enzyme murine dihydrofolate reductase (mDHFR), and cotransformed into E. coli. Interaction between the library polypeptides was required for reconstitution of the enzymatic activity of mDHFR, allowing bacterial growth.

Abstract: Protein Fragment Complementation Assays (PCA) are done in plant material using enzyme fragment constructs, for example, dihydrofolate reductase (DHFR) fragment constructs. Plant material is transformed with at least two different constructs that form different products capable of interacting to reconstitute enzymatic activity in the plant material. Detection of the activity can be done using a substrate for the enzyme in the culture medium which, when reacted with the enzyme, is converted to a detectable product. One embodiment uses a substrate that can be enzymatically converted to a detectable fluorescent product. An inducer such as rapamycin or salicylic acid can be added to the culture medium to increase the level of detectable product.
