Methods of forming cross-linked polysaccharides are disclosed in which one or more polysaccharides are dissolved in solution, gelled, modified to have a desired concentration, and subsequently irradiated. The irradiation of the gel crosslinks the polysaccharide(s) present. The disclosed techniques may be applied to various polysaccharides, including but not limited to agarose and/or hyaluronic acid.

A system and method includes a nonthermal plasma sub-system with a permeable UV filter for production and delivery of a redox gas solution to treat onychomycosis, wherein the redox gas solution comprises a reactive species dissolved in a perfluorocarbon liquid, and wherein the perfluorocarbon liquid is dispensed onto a gas-permeable membrane and wherein the reactive species may include, alone, or in combination, one or more of reactive oxygen, reactive nitrogen, reactive chlorine, or reactive bromine species, and the perfluorocarbon liquid may include perfluorodecalin.

The non-therapeutic cosmetic treatment method includes at least: —applying an active composition including at least niacinamide onto the skin of a subject, and—illuminating the skin using at least one light source emitting at a wavelength of between 620 and 690 nanometres, preferably 660 nanometres, the illumination being carried out before, at the same time as or after the application of the composition. A device is configured for implementing such a method.

Disclosed herein are photoisomerized compositions comprising anthocyanins and methods of making an use thereof. For example, disclosed herein are methods of photoisomerizing a composition, the methods comprising: irradiating a composition comprising an anthocyanin dissolved in a solvent solution with UV light; wherein at least a portion of the anthocyanin is present as a trans isomer before the irradiation; wherein the solvent solution comprises ethanol and water in a ratio of ethanol to water (volume/volume) of 99:1 to 70:30; thereby converting at least a portion of trans isomer to a cis isomer via photoisomerization to produce a photoisomerized composition. In some examples, the photoisomerized composition has a more intense and stable blue color at pH 8 relative to the composition before irradiation.

A method for improving body shape and improving skin condition using a noni fruit ferment is provided, and the method includes: administrating a composition to a subject in need thereof. The composition includes an effective amount of noni fruit ferment. The noni fruit ferment is prepared by (a) mixing glucose and noni fruit with water for extraction, to obtain a noni fruit broth, and (b) fermenting the noni fruit broth with a plurality of bacteria strains. The bacteria strains include yeast, lactic acid bacteria, and acetic acid bacteria. In step (b), the noni fruit broth and the bacteria strains are irradiated with a red light source with a wavelength of 620 nm to 750 nm. In addition, the noni fruit ferment also has at least one of the following functions: removing free radicals, improving defecation status, and improving gastrointestinal motility.

A dental composition including: ion sustained-release glass; and a carrier for supporting the ion sustained-release glass, wherein the ion sustained-release glass is fluoroaluminoborosilicate glass having a composition range of: 15% to 35% by mass SiO.sub.2; 15% to 30% by mass Al.sub.2O.sub.3; 5% to 20% by mass B.sub.2O.sub.3; 20% to 45% by mass SrO; 5% to 15% by mass F; and 0% to 10% by mass Na.sub.2O.

Semisolid oral dispersions for improving the health and/or appearance of the oral cavity. The semisolid oral dispersions include hydrophilic active agent particles in hydrophobic phase. The hydrophilic active agent particles can include bleaching agents, antimicrobial agents, anticalculus agents, and/or combinations thereof. The hydrophilic active agent particle can have a solubility in water of at least about 20 parts, by weight of the particles, in about 100 parts, by weight, of water.

Compositions for application to skin of a subject comprising (a) an unsaturated organopolymer, (b) a hydride functionalized polysiloxane and (c) an environment-responsive agent that is capable of transporting out of the composition or facilitates out-transport of one or more beneficial agents from the composition after the composition is applied to a subject. Alternatively, the compositions comprise (a) a bifunctional organopolysiloxane polymer having one unsaturated group and one hydride and (b) the environment-responsive agent. The environment-responsive agent may be a volatile agent and the compositions can be used to create a thin film on the skin of a subject wherein the volatile agent is capable of transporting out of the film. In one embodiment, the volatile agent is transported out of the composition by convection. In one embodiment, the volatile agent is transported out of the composition by diffusion.
