Abstract: Citrate buffer, a polyol, a polymer, a salt, a preservative are used individually or in combination in a liquid coating or film composition with DispersinB to stabilize the DispersinB at an ambient or higher temperature. The polyol may comprise sorbitol, glycerol, propylene glycol, isomalt, erythritol, or maltitol. The polymer may comprise poloxamer 407, polyvinyl alcohol, gelatin, cellulose, hydroxyethyl cellulose, carboxymethyl cellulose, or polyvinylpyrrolidone. The salt may comprise NaCl, Na2SO4, NH4Cl, KCl, KNO3, or K2SO4. The preservative may comprise ethylenediaminetetraacetic acid (EDTA), levulinic acid, or anisic acid.

Abstract: Particular antimicrobials are identified for efficacy in a composition with DispersinB to enhance biofilm dispersal and inactivation of biofilm embedded bacteria.

Abstract: Methods and devices are provided for rejuvenating the skin of a subject, e.g., a human. The methods include moving a blade across a skin region of the subject. The skin region, for example, can include predominantly vellus hairs.

Abstract: Shaving systems and related methods are disclosed. In some embodiments, a shaving system includes a first electrical power source, a razor, and a second electrical power source in the razor, wherein the first electrical power source is capable of charging the second electrical power source.

Abstract: An arrangement for a direct methanol fuel cell includes a fuel cartridge that supplies a source of fuel to the direct methanol fuel cell. The fuel cartridge has a surface area enhanced planar vaporization membrane residing in the fuel cartridge. The arrangement also includes a fuel reservoir that receives fuel from the fuel cartridge, the fuel reservoir arranged to deliver fuel to the fuel cell. The fuel reservoir also including a surface area enhanced planar vaporization membrane residing in the fuel reservoir. The combination of the surface area enhanced planar vaporization membranes residing in the fuel cartridge and reservoir provides a dual stage vaporization of fuel to the fuel cell. Other features included are passive or active arrangements to increase the temperature of the fuel or reduce pressure in the fuel container to enhance rate of vaporization.
