Abstract: An electrochemical oxygen sensor includes a sensing surface having a working electrode and a reference electrode, a hydrophilic layer formed from an oxygen diffusion-limiting layer emulsion overlaying the working electrode and a hydrophobic membrane formed from a hydrophobic solution disposed over the hydrophilic layer. The hydrophilic layer contains an epoxy network and a hydrophilic polymer. The hydrophobic layer contains an acetate copolymer and a cross-linking agent that reacts with the liquid epoxy resin in the hydrophilic layer forming the epoxy network where the hydrophobic member is water vapor and oxygen permeable.

Abstract: A dental floss member and a dental floss holder are disclosed. The dental floss member includes a linear type dental floss having a predetermined length, a first fixer disposed at one end of the dental floss, and a second fixer disposed at the other end of the dental floss. The dental floss holder includes a body having a first corresponding fixer to which the first fixer is fixed and a mounting part on which a section for use of the dental floss is mounted, and a second corresponding fixer disposed at the body and to which the second fixer is fixed.

Abstract: Biocompatible materials that have the ability to release nitric oxide (NO) in situ at the surface-blood interface when in contact with blood. The materials which may be polymers (e.g., polyurethane, poly(vinyl chloride), silicone rubbers), metals, such as stainless steel, carbon, and the like are provided with biocatalysts or biomimetic catalysts on their surface that have nitrite, nitrate, and/or nitrosothiol-reducing capability. Illustratively, the catalysts are adsorbed or immobilized at the surface of the material. The catalysts can act on endogenous nitrite, nitrate, or nitrosothiols within the blood creating a local increase in the NO levels at the surface of the material. An illustrative enzymatic biocatalyst is mammalian xanthine oxidase. In another illustrative embodiment, a biomimetic catalyst is a copper (Cu(II)-ligand complex, e.g. dibenzo[e,k]-2,3,8,9-tetraphenyl-1,4,7,10-tetraaza-cyclododeca-1,3,7,9-tetraene. In some cases, lipophilic salts of nitrite/nitrate (e.g.

Abstract: Disclosed is a system for purchasing and managing pets. The system comprises a customer node (100), a server node (120), and a supplier node (170), each node being connected by Internet. According to a request for purchase, training, referral, quarantine, etc. of pets from the customer node, information about various pets and a request form are displayed on the customer node. The customer fills in pertinent empty spaces in the request form to achieve a wanted trade. The request form has fundamental purchase items (FPI) containing contents that the customer must select. The request form further has an optional purchase item (OPI) that is optionally selected when the customer wants additional purchase to the FPIs out of free will. But the OPI doesn't directly affect arrangement of the trade. The request form further has a requisite purchase item (RPI) that the customer automatically attains without a separate selection once the trade is arranged by the selection among the FPIs. The RPI is cancelable later.
