Abstract: A novel recombinant human neurokinin-1 receptor short form (hereinafter identified as human NK1R sF) is disclosed which has been prepared by polymerase chain reaction techniques. Also disclosed is the complete sequence of human NK1R sF complementary DNA; expression systems, including a CHO (Chinese hamster ovarian cell line) stable expression system; and an assay using the CHO expression system.NK1R sF, can be used in an assay to identify and evaluate entities that bind substance P receptor or NK1R sF. The assay can also be used in conjunction with diagnosis and therapy to determine the body fluid concentration of substance P antagonists in arthritis patients.
Abstract: The compounds of formula (I) ##STR1## wherein R is selected from the group hydroxymethyl and carboxy, have been identified as metabolites of 5.alpha.-23-methyl-4-aza-21-nor-chol-1-ene-3,20-dione and are believed to be active as testosterone 5.alpha.-reductase inhibitors and would thus be useful for treatment of acne, seborrhea, female hirsutism or benign prostatic hypertrophy.
Abstract: A method for inhibiting the deposition of pitch on and/or for removing pitch from the surfaces of pulping and papermaking machinery by adding an effective amount of a melamine formaldehyde-type polymer to a pulp slurry or furnish in contact with said machinery.
Abstract: A method for treating an ink-laden wastewater stream comprising adding an effective amount of a melamine-aldehyde polymer to the ink laden stream being treated and segregating at least some portion of the resulting ink-laden agglomerated solids from the treated water.
Abstract: Method for controlling fouling in high efficiency cooling tower fill using low molecular weight 2-acrylamido-2-methylpropyl sulfonic acid/acrylic acid-type polymers.
Abstract: A method for increasing the porosity of fly ash comprising adding an effective amount of a polymer/nitrate composition to fly ash produced from the combustion of fuels such as coal.
Abstract: Methods of treating circulating water containing oversprayed, water-borne paint, such as in a paint spray booth operation, with aluminum salts such as aluminum chloride or polyaluminum chloride and a flocculant, resulting in removal of sludge from the paint spray booth water.
Abstract: Methods of treating circulating water containing over-sprayed, water-borne paint, alone or in combination with over-sprayed solvent-borne paint, as in a paint spray booth operation, comprise maintaining the alkalinity of the paint spray booth water between about 50 and 2000 ppm, on a calcium carbonate basis, by adding an alkalinity source thereto, maintaining the pH between about 6.0 and 9.0, adding a melamine polymer to the water, adding an aluminum salt to the water, contacting the over-sprayed paints with the alkalinity-adjusted paint spray booth water before or after addition of the melamine polymer and aluminum salt, adding an effective amount of a flocculant to the paint spray booth water, and removing resulting sludge from the paint spray booth water.
Abstract: Improved tellurium-containing coating compositions and a method for applying a tellurium-containing coating to a metallic surface characterized by the presence of tellurium and an organic acid solubilizing agent.
Abstract: An alkoxybenzotriazole, in combination with mercaptobenzothiazole, tolyltriazole, benzotriazole, a substituted benzotriazole and/or 1-phenyl-5-mercaptotetrazole, is used to inhibit the corrosion of metallic surfaces, particularly copper surfaces, in contact with an aqueous system. Systems and compositions are also claimed.
Abstract: A novel method of treating circulating water containing over-sprayed, water-borne paint, such as in a paint spray booth operation, comprises adjusting the alkalinity of the paint spray booth water to between about 20 and 600 ppm, on a calcium carbonate basis, by adding a designated alkalinity source thereto, adding a cationic potato starch to the water, contacting the over-sprayed, water-borne paint with the alkalinity-adjusted paint spray booth water after addition of the cationic potato starch, adding an effective amount of a polymer floccing agent to the paint spray booth water, and removing resulting sludge from the paint spray booth water.
