Abstract: A skin dressing comprises a hydrated hydrogel material including a source of lactate ions and a supply of glucose, optionally also including a source of zinc ions and a source of iodide ions. The dressing has beneficial effects on skin.

Abstract: The present invention provides a composition comprising an enzyme, e.g. oxidase enzyme, a source of zinc and/or ammonium ions and a source of lactate ions. The compositions are typically sterilised by exposing the compositions to sterilising radiation, e.g. gamma radiation. The incorporation of a source of zinc and/or ammonium ions and a source of lactate ions, e.g. zinc L-lactate, in the enzyme-containing composition results in an improvement in enzyme activity post-sterilisation. The presence of a source of zinc and/or ammonium ions and a source of lactate ions in the composition therefore has a protective effect on the enzyme during exposure to sterilising radiation so that good recovery of enzyme activity can be obtained.

Abstract: A skin dressing comprises a first dressing component (16) carrying oxidoreductase enzyme in dried condition; and a second dressing component (18) carrying a source of water, such that when the first and second dressing components are placed in fluid communication with each other, water migrates from the second component towards the first comportent and acts to hydrate enzyme carried by the first component, at least at the surface of the first component. The dressing components are kept separate before use, e.g. being sealed in separate sterile, water-impervious packages such as laminated aluminium foil pouches. In use of the dressing, the second dressing component is located on the skin of a human or animal, e.g. over a wound to be treated or on a region of skin to be treated for cosmetic or therapeutic purposes such as for treatment of acne or other skin conditions. The first dressing component is placed on top of the second component in fluid communication therewith.

Abstract: An interface tube is provided for an image display device. In one embodiment, an interface tube having an inside surface and a center region where the at least a portion of the inside surface includes light-disbursing elements. The light-disbursing elements may be configured to direct a substantial portion of reflected light away from the center region to prevent center region from exceeding a specified temperature.

Abstract: A skin dressing, particularly a wound dressing, comprises oxidoreductase enzyme and, optionally, peroxidase enzyme, wherein the enzyme(s) are present in hydrated condition, e.g. being present in one or more hydrated hydrogels. The dressing is used by being located on the skin of a human or animal e.g. over a wound. The oxidoreductase enzyme catalyses a reaction that produces hydrogen peroxide from an appropriate substrate, the substrate either being naturally present in body fluids and/or being supplied separately and/or being incorporated into the dressing. The currently preferred oxidoreductase enzyme is glucose oxidase. The catalyses reaction of ?-D-glucose substrate to give hydrogen peroxide and gluconic acid. A mixture of oxidoreductase enzyme can undergo reaction (optionally catalysed by the peroxidase enzyme) to produce a variety of species including reactive oxygen intermediates that have antimicrobial properties and that can therefore assist in promoting wound healing.

Abstract: A point of purchase research device includes a housing having a user surface and a mounting surface adapted to cooperate with a store shelf. The housing further includes a display device affixed adjacent to the user surface and communicatively connected to a user input device and a control unit. The control unit having a processor communicatively connected to the display device and the user input device. The control unit executes a control routine on the processor and is configured to control the display device to gather consumer information from the user input device.

Abstract: A lip guard is provided for protecting the lips of brass and woodwind players who wear braces. Each lip guard comprises a strip of thermoplastic material that is heated, molded into place over the teeth and braces of the musician, and then allowed to cool. The lip guards thus provide a smooth, protective barrier between the musician's lips and braces that protects the lips against chaffing that might occur as the mouthpiece of a musical instrument presses back against the musician's lips. The lip guards can be removed from the teeth quickly and easily between performances and can be reused from performance to performance. If adjustments are made to the musician's braces, the lip guards can be easily and conveniently reheated and remolded to accomodate the new shape.

Abstract: A conductive polymer composition having PTC characteristics comprising a polymer matrix, constituting from 20 to 98 percent by weight of the composition, throughout which is dispersed a mixture of conductive carbon blacks constituting from 2 to 80 percent by weight of the composition, the mixture comprising a first conductive carbon black and a second conductive carbon black, each of the carbon blacks having a structure level, as measured by DBP technique, of 40 to 150 cc/100 g and each constitutes from 1 to 40 percent by weight of the composition, the first carbon black comprising particles having average size in the range from 35 to 300 nm and the second carbon black comprising particles having average size in the range from 15 to 25 nm.
