    Abstract: The present invention provides a paper product for use in sterilizing an area. The paper product contains at least one paper sheet or pellet containing one or more dry chemical materials, one or more dry deliquescent materials, or mixtures thereof. The dry chemical materials are either inactive antimicrobial or biocidal chemical materials or are capable of reacting with another chemical material to produce one or more active antimicrobial or biocidal chemical materials. When the paper product is placed in an atmosphere containing water vapor, the deliquescent material(s) attracts water and dissolves, thereby either hydrating and rendering active the inactive antimicrobial or biocidal chemical material(s), or providing a medium in which the chemical materials will react to produce one or more active antimicrobial or biocidal chemical materials.

  • Publication number: 20030044315
    Abstract: A method for selective perfusion of fluids through blood vessels is controlled by the pressure in the blood vessels. A tubing line open at the proximal end for the perfusion of fluids through a tissue region is introduced into a patient's blood vessel in which perfusion is to be performed. The vessel is sealed off from the line in the area of its proximal end, and fluid is pumped into the vessel. The method is characterized in that a specific set value for the internal pressure of the vessel is measured, and the perfused flow of fluid is regulated during pumping in such a way that the set value for the internal pressure of the vessel is kept as closely as possible.

  • Publication number: 20030044316
    Abstract: A test strip having the capability of separating blood cells from whole blood, wherein it has a porous reagent layer comprising beads, an inorganic gel and a reagent that causes a detectable reaction with a substance to be detected, and a substrate that supports the reagent layer, wherein the beads are adhered to each other with the inorganic gel, and interstices are formed between the beads to trap a solid. The test strip can thus be used for separating blood cells from a whole blood including blood cells and plasma and detecting a substance to be detected, such as glucose, contained in plasma. The use of the test strip allows the measurement of a substance to be detected even by measurement of a transmitted light, the exhibition of good oxygen permeability, and thus can be used for measuring a substance to be detected with improved accuracy.

    Abstract: A process for preparing molecular sieves of type Y faujasite structure is described, as well as pre-shaped bodies of faujasite structure type Y molecular sieves. The process comprises preparing a precursor gel from a source of silica-alumina or a source of alumina and a source of silica with a template agent at a SiO2/Al2O3 greater than 7 and suitable for forming a type Y zeolite, drying the precursor gel and contacting the dried precursor gel with steam, optionally followed by caustic washing, without the formation of crystalline phases other than type Y zeolite being observed. Advantageously, the pre-shaped bodies prepared with the precursor gel of Y zeolite, when subjected to the process of the invention, will have their outer surface covered by type Y zeolite crystals. The molecular sieves so obtained may be employed as catalysts or adsorbents in various processes of the chemical or oil industry.

  • Publication number: 20030044352
    Abstract: This invention provides a method for evaluating efficacy of treatment of animals and humans using compositions comprising bacterial DNA and bacterial DNA preserved and complexed on bacterial cell walls. Biological markers such as cytokines, soluble FAS ligand (sFasL) and apoptosis markers released from cells following treatment are measured to assess efficacy of treatment and to identify non-responding patients. This method facilitates identification of animals and humans who should and who should not receive therapeutic administration of these bacterial compositions, and provide a means to evaluate efficacy of such treatment.

  • Publication number: 20030044353
    Abstract: The invention relates to activatable imaging probes that includes a chromophore attachment moiety and one or more, e.g., a plurality of, chromophores, such as near-infrared chromophores, chemically linked to the chromophore attachment moiety so that upon activation of the imaging probe the optical properties of the plurality of chromophores are altered. The probe optionally includes protective chains or chromophore spacers, or both. Also disclosed are methods of using the imaging probes for optical imaging.

  • Publication number: 20030044360
    Abstract: Disclosed is a process and composition for bleaching teeth made up of two components blended together before each application. The method and composition offers faster results while significantly reducing the possibility of user discomfort. One of said components comprises carbamide peroxide, the other contains salts and hydroxides and/or oxides of metals belonging to the first or second group of the Periodic Table which stimulate the generation of radical oxygen. In one embodiment, the first part comprises up to 50% water by weight and optionally comprises a stabilizer. In some embodiments, the first component is substantially colorless and the second component comprises a dye indicator which discolors or loses color when exposed to radical oxygen generated by the mixing of the two components.
