Abstract: Naturally-derived bioprosthetic materials are treated with epoxide crosslinking agents. In some embodiments, the tissue is crosslinked with low molecular weight epoxides in aqueous solutions at high pH levels. In other embodiments, the tissue is crosslinked at physiologic pH levels with epoxide crosslinking agents catalyzed with tertiary or quaternary amines, such as Tris or imidazole. In an advantageous embodiment, bioprosthetic tissue is crosslinked and derivatized with an anticalcification agent, such as a polyphosphonate anticalcification agent, using a polyphosphonate:polyepoxide monoadduct.

Abstract: A terry cloth article having a frosted appearance includes a plurality of naps the tips of which are bleached, and is produced by a process including the steps of impregnating granules of an absorbent material with a solution including a bleaching agent, and contacting a dyed terry cloth with the granules for a time sufficient to bleach at least a portion of the dye from the naps of the terry cloth. After residual bleaching agent remaining on the terry cloth is neutralized, the terry cloth is subsequently contacted with a solution including an effective amount of an anti-peeling agent for a time sufficient to substantially eliminate peeling. Optionally the terry cloth can subsequently be overdyed with a second dye of a different color than the color of the terry cloth.

Abstract: Modified wool having improved shrink-proofing property is obtained by a two step process in which raw material wool is first immersed in a first aqueous bath containing a water-soluble organic phosphine and is then immersed in a second aqueous bath containing a modifying agent selected from epoxy compounds, ethyleneimine compounds, urea, substituted urea compounds, thiourea, substituted thiourea compounds, alkylene carbonates, unsaturated carboxylic acids, derivatives of unsaturated carboxylic acids, unsaturated nitriles, unsaturated alcohols, esters of an unsaturated alcohol, sulfonic acid salts having a vinyl group, cyanic acid salts, nonionic surfactants of a poly(alkylene oxide) type, salts of sulfates of the nonionic surfactants and silane coupling agents having a vinyl group. The treatment may also be performed by a one step process in which wool is immersed in an aqueous bath containing the above phosphine compound and a modifying agent selected from the above.

Abstract: The preparation of water-insoluble, bactericidal, peroxide-containing products, by reaction of magnesium acetate with hydrogen peroxide, and products obtained are disclosed. Processes for application and deposition of these reaction products on natural, synthetic and blend fibrous substrates are also disclosed. The modified fibrous substrates thus produced inhibit the growth and spread of odor- and disease-causing gram-positive and gram-negative bacteria and the antibacterial activity of the modified fibrous substrates is durable to repeated launderings.

Abstract: In a washing method, a web of textile goods is wetted with a washing-active liquid and the liquid is caused to foam by steam which is blown at high pressure into a back side of the web of goods with a pile on the front side. The steam is discharged from a nozzle slot that extends transversely across the web of goods. The nozzle directs the steam against the web and through it. The foam which then suddenly forms is then drawn off by a vacuum or suction together with the liquid still in the pile from the pile side of the web.

Abstract: Novel bleaches, a method for bleaching substrates using these materials and detergent compositions containing same are reported. The bleaches are phosphinoyl imines. Substrates such as fabrics may be bleached in an aqueous solution containing the phosphinoyl imines and a peroxygen compound.

Abstract: The structurally stable gelled electrolyte of the present invention includes a base electrolyte, a three-dimensional polymer precursor that is radiation curable and an electrically non-conducting solvent gelling agent. The base electrolytes of this invention are comprised of an aprotic liquid and a dissolved ionizable alkaline metal salt. The preferred radiation curable polymer pre-cursors of this invention include trimethylol propane ethoxy triacrylate (TMPEOTA) and poly(ethylene glycol) diacrylate (PEGDA).

Abstract: A cold water washing method for reducing the soil load on a textile by introducing the textile and cold water into an internal assembly within a washing machine. The method includes a first break wash wherein the textile, water, and a solvent are introduced into the washing machine to initiate soil removal. In a second break wash, a surfactant and an alkali are added to the first break wash to continue the washing cycle. The combined first and second break washes are drained from the internal assembly and the textile is rinsed with water. After draining the first rinse from the internal assembly, a second rinse including ozonated water and an acid is introduced into the internal assembly. The second rinse is drained from the internal assembly and a third rinse, which includes ozonated water, is introduced into the internal assembly to rinse the textile.

In particular, an effective amount of a pyrazine derivative of the invention may be administered into a body of a patient. The pyrazine derivative that is in the body may be exposed to visible and/or infrared light to cause spectral energy to emanate from the pyrazine derivative. This emanating spectral energy may be detected and utilized to determine renal function of the patient.
