Limited-play optical medium with improved shelf stability are formed from a plurality of layers, including in sequence: (a) a first substrate layer; (b) a data layer; (c) a reflective layer; (d) a reactive layer comprising a dye having a reduced state and an oxidized state and further comprising an oxidized form of a reducing agent effective to convert the dye from the oxidized state to the reduced state, and (e) a second substrate layer. The dye in the reduced state is substantially transparent to light of wavelengths used to read the optical medium, and the dye in the oxidized state absorbs light of wavelengths used to read the optical medium. The reflective metal layer is formed from a metal or metal alloy that is not significantly oxidized by the oxidized form of the reducing agent. For example, the reflective metal layer is suitably formed from silver or gold.

Methods for production of platelets from pluripotent stem cells, such as human embryonic stem cells (hESCs) and induced pluripotent stem cells (iPSCs) are provided. These methods may be performed without forming embryoid bodies or clusters of pluripotent stem cells, and may be performed without the use of stromal inducer cells. Additionally, the yield and/or purity can be greater than has been reported for prior methods of producing platelets from pluripotent stem cells. Also provided are compositions and pharmaceutical preparations comprising platelets, preferably produced from pluripotent stem cells.

Techniques and devices are presented for communicating exposure to a potentially harmful stimulus. The devices include a stimulus sensitive gel which changes volume in response to exposure to the stimulus and thereby presents a contrast in color that serves as a visual indicator that exposure to the stimulus has occurred.

A closure for releasably securing to a container adapted for storing foodstuff or a beverage, the closure comprising closing means (14) for closing a mouth of the container and securing means (22,23) for securing it in a closed position, the closing means and the securing means being formed of a plastics material comprising polyoxymethylene so as to provide a substantial gas barrier to the passage of oxygen and/or carbon dioxide therethrough, The closure may have a sealing member (18) formed of resilient material (compared to the rigid material of the remainder of the closure) for providing a seal between the closure and the container. The sealing member may be provided on a bore component which projects into the container so that, in use, it seals against an internal surface of the container. The sealing member may be an o-ring (18) formed of an elastomer, e.g. nitrile butadiene rubber. A foodstuff or beverage container, e.g. in the shape of a wine glass or the shape of a beer glass, having such a closure is also described. The use of a plastics material comprising polyoxymethylene for closing a container provides a barrier to the ingress of oxygen and/or to the egress of carbon dioxide to improve the shelf life of the product is also described.

Disclosed are antimicrobial emulsions, products comprising the emulsions, and methods of use.

The invention discloses a decorative material midbody with split-packaged chemical additives and relates to a novel material, in particular to the production and the application of a novel decorative material. The decorative material midbody with split-packaged chemical additives is packaged by classification according to the length of quality guarantee periods of component materials, wherein a component A consists of chemical additives, fillers and pigments with the quality guarantee period being above six months, and a component B consists of hydraulic inorganic solidifying materials with the quality guarantee period being only three months. The decorative material midbody with split-packaged chemical additives has the advantages that the advantage that the quality guarantee period of the component A is long is exerted, the difficulty in storage and transportation is reduced and the wastage of fillers, pigments and additives is reduced; and the emphasized safekeeping and storage of the component B with the short quality guarantee period are facilitated, the component B can be taken out from the unused midbody for timely use or be replaced by new component B when the deadline of the quality guarantee period approaches, and the situations of potential engineering hazards and energy wastage are avoided.

This invention is directed to an improvement in binders particularly suited for use in preparing nonwoven products and to the nonwoven products. The improved binders comprise a blend of emulsion polymerized ethylene-vinyl chloride (EVCl) polymer and an emulsion polymerized self crosslinkable vinyl acetate-ethylene-N-methylolacrylamide (VAE-NMA) polymer. The blends of the EVCl polymer emulsion and the VAE-NMA polymer emulsion can be applied to cellulose and cellulose/synthetic nonwoven substrates and cured in the absence of an acid catalyst to provide a self-sustaining web having excellent wet strength performance. The blends of EVCl and VAE-NMA polymers do not require an acid catalyst to facilitate cure.

A method including improving a property of a paper product precursor by adding a molten wax suspension to paper product precursor, the molten wax suspension including a suspension of liquid wax particles in a liquid solvent, the liquid wax particles being at a temperature higher than the melting point of the wax. The molten wax suspension may be added to the paper product precursor in a production line prior to making a finished paper product. A finished paper product may be made from the paper product precursor.

Formulations, methods and devices for producing formulations and methods for nebulizer delivery of formulations of water-insoluble drugs and drugs requiring storage in aqueous or other water-miscible pharmaceutically unacceptable vehicles for stability are provided. Also provided are methods for minimizing wastage of drugs administered by nebulizer, and for the achievement of quantitative dosing with diluent from a mass marketed formulations, which because of the mass market is much less costly per dose than formulations manufactured specifically for much lower volume medical use.

A compound comprising a metal chelate linked to a hexose carrier for use as a metallopharmaceutical diagnostic or therapeutic agent is provided. The compound is suitable for imaging by single-photon emission computed tomography, computer assisted tomography, magnetic resonance spectroscopy, magnetic resonance imaging, positron emission tomography, fluorescence imaging or x-ray.

The invention provides polyamine derivatives, a use of the polyamine derivatives for the transfection of polyanions into cells, and a method of transfecting cells with a polyanion, comprising mixing said polyanion with a polyamine derivative e.g. in a buffer and treating said cells with the mixture obtained in the previous step.

There is provided a condom having a coating or deposit of a composition which includes a physiologically-active agent such as glyceryl trinitrate, wherein the condom has been treated with a neutralising or acidic material such that the condom, when immersed in water, results in the water having a pH of 7 or less. The condom may be treated with an acidic slurry of dusting powder. Also provided is a process for the manufacture of condoms, in which the process includes the steps of: 1) treating the formed condoms with a neutralising or acidic material; and 2) thereafter applying to the condoms a composition including a physiologically-active agent such as glyceryl trinitrate, wherein the condoms, when immersed in water, results in the water having a pH of 7 or less.

The present invention comprises buffered compositions and methods for antiseptically treating or pretreating anatomic surfaces for invasive surgical or treatment procedures. The compositions and methods according to the present invention find use in treating skin, gums and ocular surfaces for injections and other procedures. The buffered compositions of the present invention comprise antiseptic agents, optionally within an aqueous gel or semi-gel formulation, to provide enhanced methods of treating anatomic surfaces such as the gums or eye prior to surgical or other invasive procedures. Buffered compositions provide additional benefits to standard non-buffered preparations including decreased toxicity to the anatomic surfaces, which improves post-procedural discomfort and vision in the case of ocular surfaces.
