Abstract: A transdermal patch is provided, wherein the patch comprises a cross-linked poly(ethylene oxide) hydrogel loaded with naltrexone, or a pharmaceutically acceptable salt or solvate thereof, and an occlusive adhesive tape. The poly(ethylene oxide) hydrogel has a crosslink density of at least 4.5×10?4 mol cm?3 and not more than 16×10?4 mol cm?3. Also provided are methods for preparing naltrexone-loaded cross-linked poly(ethylene oxide) hydrogels, transdermal patches for use as a medicament, for example in the treatment of a specified condition with LDN therapy.
Abstract: A method of preparing hydrophobic silica particles includes the step of reacting together in a single step a mixture of silane ether monomers and organically modified silane ether monomers with a hydrolyzing agent. The method also includes producing hydrophobic silica microparticles and nanoparticles that can include dyes and/or magnetizable components. The silica nanoparticles can be used in the detection, visualization and/or analysis of latent fingerprints.
Abstract: The present subject matter relates generally to antioxidant compounds having the formula (I): wherein each of R1, R2, R3, and R4 are as defined below. These compounds are potentially useful as, for example, antioxidants.
