Abstract: The present invention pertains to liquid droplets including a polymer according to Formula (I) and to their use in an aqueous medium for the uptake of compounds from outside the droplets into the droplets for separation, storage and/or reaction of compounds inside the droplets, as well as associated methods of production of the polymer.

Abstract: The present invention provides compositions and methods for the treatment or prevention of a neurological disease or disorder of the central nervous system (e.g., a storage disorder, lysosomal storage disorder, neurodegenerative disease, etc.) by reconstitution of brain myeloid cell and microglia upon transplantation of hematopoietic cells enriched in microglia reconstitution potential. The invention also provides compositions and methods for ablating and reconstituting microglia.

Abstract: A fragrance-containing microparticle of water-insoluble polymeric material, the polymer having a glass transition temperature of from 0° C. to 50° C. and a zeta potential lying within the ranges ?40 mV to ?5 mV and +5 mV to +45 mV. The microparticles have enhanced substantivity to hair, resulting in a longer-lasting fragrance.

Abstract: Disclosed are methods, compositions, reagents, systems, and kits to prepare and utilize poly (?-amino ester) (PBAE) polymers, which are synthesized via Michael addition reactions of diacrylates and amines disclosed herein. Various embodiments utilize lactones and lactone derivatives to generate the diacrylate compounds. The PBAE polymers are shown to be effective biodegradable carriers for the delivery of an agent such as an organic molecule, inorganic molecule, nucleic acid, protein, peptide, polynucleotide, targeting agent, an isotopically labeled chemical compound, vaccine, or an immunological agent.
