Abstract: A process for preparing a dispersion polymerized color toner for developing latent electrostatic images includes polymerization of a macromer in a liquid organic medium in which the macromer or the resulting polymer resin is not soluble. The liquid organic medium comprises a polymeric dispersion stabilizer. A macromer mixture comprising macromer, a colorant and a charge control agent may be polymerized in the dispersed state to produce the toner. Alternatively, the macromer is polymerized in the dispersed state to produce a particulate polymer resin. The particulate polymer resin formed is a functionalized resin having sites suitable for interacting with functionalized dyes that have complementary functionality. The functionalized dye is then applied to the resin particles typically with a dyeing aid, or surfactant. Toners produced by the inventive processes are substantially free of contamination by the liquid organic medium used during dispersion polymerization and/or dispersion dyeing.

Abstract: We describe a strategy for designing and implementing protein-fragment complementation assays (PCAs) to detect biomolecular interactions in vivo and in vitro. The design, implementation and broad applications of this strategy are illustrated with a large number of enzymes with particular detail provided for the example of murine dihydrofolate reductase (DHFR). Fusion peptides consisting of N- and C-terminal fragments of murine DHFR fused to-GCN4 leucine zipper sequences were coexpressed in Escherichia coli grown in minimal medium, where the endogenous DHFR activity was inhibited with trimethoprim. Coexpression of the complementary fusion products restored colony formation. Survival only occurred when both DHFR fragments were present and contained leucine-zipper forming sequences, demonstrating that reconstitution of enzyme activity requires assistance of leucine zipper formation. DHFR fragment-interface point mutants of increasing severity (lie to Val, Ala and Gly) resulted in a sequential increase in E.

Abstract: Liquid hydrocarbons are gelled by the introduction of a phosphate ester and a crosslinking agent. Gelling times and viscosities are improved through the use of an enhancer which is, preferably, an oxyalkylated amine or a blend of an oxyalkylated amine with another amine or a non-nitrogen-containing component. Preferred phosphate esters are ether phosphate esters.

Abstract: An improved single- or multiple-dose syringe having a conventional housing and an improved plunger configuration carrying a medicament- or saline-filled cartridge the contents of which are sequentially dispensed after the dispensing of a volume of a drawn-up primary fluid. A method for sequential administration of medicinal fluids using the improved syringe is also a part of the invention.

Abstract: The administration of histidine is able to prevent and ameliorate tissue and cellular damage which is caused by damaging levels of cytokines and growth factors. It is shown that histidine, when administered in therapeutic quantities is able to inhibit cytokines and growth factors involved in cell and tissue damage. In addition, the method of administering histidine to inhibit these molecules can prevent and ameliorate tissue, vessel and cell damage from restenosis, burns, surgical procedures and other disorders which cause and result from damaged tissues, vessels and cells.

Abstract: The present invention relates to methods for protecting the eye from degenerative eye conditions by administering prophylactic histidine compositions. The invention also relates to methods for treating ocular inflammation resulting from various causative agents, by administering therapeutic histidine compositions. The invention relates further still to novel histidine compositions for carrying out the present methods.

Abstract: An innovative liquid mulch apparatus for the production of thin, lightweight and fastly growing sod over an impervious surface such as plastic sheeting are provided. The apparatus of the invention includes, among other components, a transportable agitating tank and a trailing planter assembly that facilitates the liquid mulch method of manufacturing sods.

Abstract: A method of preventing or reducing fluid and electrolyte losses in mammalian subjects under the effect of a stimulus that directly or indirectly causes such losses, by administering a therapeutically effective amount of D-histidine, L-histidine, a racemic mixture thereof, a non-racemic mixture thereof, and pharmaceutically acceptable salts in conjunction with a carrier. In one embodiment the method is useful in reducing or preventing intestinal tract fluid secretions, and fluid and electrolyte losses associated with diarrhea arising from a number of causative agents, such as infectious diarrheas and non-infectious diarrheas. Various therapeutic regimes of histidine administration and formulation are embodied. Therapeutic compositions of histidine in combination with other medicaments, e.g., those that produce a diarrheal side-effect, are disclosed as another embodiment.
