Blood-brain barrier permeable peptide compositions that contain variable antigen binding domains from camelid and/or shark heavy-chain only single-domain antibodies are described. The variable antigen binding domains of the peptide compositions bind to therapeutic and diagnostic biomarkers in the central nervous system, such as the amyloid-beta peptide biomarker for Alzheimer's disease. The peptide compositions contain constant domains from human IgG, camelid IgG, and/or shark IgNAR. The peptide compositions include heavy-chain only single-domain antibodies and compositions with one or more variable antigen binding domain bound to one or more constant domains.

Methods of and compositions for breaking down a biofilm or inhibiting, preventing or treating a microbial infection that produces a biofilm are disclosed, which involves administration of an interfering agent capable of specifically competing, titrating, or inhibiting the binding of an HU protein to a microbial DNA. By competing with HU proteins that bind to DNA scaffold in the biofilm, these interfering agents destabilize the biofilm leading to destruction and removal of the biofilm by the immune system. Further method and composition aspects are contemplated in relation to infections caused by bacteria that export an HU protein.

The present invention generally relates to microfluidic droplets and, in particular, to multiple emulsion microfluidic droplets. In certain aspects, particles such as gel particles can be prepared in an aqueous carrier from aqueous droplets (or a non-aqueous carrier from non-aqueous droplets). For example, in some embodiments, double-emulsion droplets of a first fluid, surrounded by a second fluid, contained in a carrier fluid may be prepared, where the first fluid forms a gel and the second fluid is removed. For instance, the second fluid may be dissolved in the carrier fluid, or the second fluid may be hardened, then removed, for example, due to a change in pH. Other embodiments of the present invention are generally directed to kits containing such microfluidic droplets, microfluidic devices for making such microfluidic droplets, or the like.

This disclosure related to modular and programmable peptide-oligonucleotide chimeras comprising of peptide and oligonucleotide segments interlinked by an organic core are presented and their assembly as morphologically-tunable soft materials, for example, nanostructure compositions comprising a plurality of compounds comprising a peptide segment and an oligonucleotide segment interlinked by an organic core moiety.

A particulate, modified release barrier coated drug-cation exchange resin complex comprising a core composed of a drug complexed with a pharmaceutically acceptable ion-exchange resin is provided. Methods of making and products containing this coated complex are described.

A method of treating a mammal, comprising administering a therapeutically effective amount of a poly-oxygenated metal hydroxide composition to a mammal to reduce a proliferation of hypoxic carcinoma cells, wherein the poly-oxygenated metal hydroxide composition comprises a clathrate containing free oxygen gas (O.sub.2) molecules. The carcinoma cells may comprise lung carcinoma (A549). The poly-oxygenated metal hydroxide material is configured to provide bioavailable oxygen gas molecules to a mammal when administered to the mammal. The poly-oxygenated metal hydroxide composition can be administered intravenously, directly to carcinoma cells, and orally. The composition may comprise a fluid, where the poly-oxygenated metal hydroxide composition is soluble in the fluid.

Disclosed are modified pigment epithelium-derived factor (PEDF) peptides, particulate carrier prodrugs thereof, and pharmaceutical compositions comprising the peptides or particulate carrier prodrugs. The peptides, particulate carrier prodrugs, and pharmaceutical compositions may be used to treat diseases and disorders that are amenable to treatment with anti-angiogenic agents, anti-tumorigenic agents, anti-fibrotic agents, chemotherapy-protecting agents, and immune stimulating agents.

The present invention relates to an immunostimulatory nanocomplex. The immunostimulatory nanocomplex comprises polyglutamic acid (PGA), a first positively charged substance, a second positively charged substance and a dengue viral protein for holding the dengue viral protein inside. The immunostimulatory nanocomplex is characterized by having a nonuniformally and positively charge distribution along a radial direction thereof. The nonuniformally and positively charge distribution comprises a first electrically charged portion having substantially electrical neutrality, a second electrically charged portion surrounding the first electrically charged portion, and a third electrically charged portion surrounding the second electrically charged portion. The third electrically charged portion has a third volume charge density more than a second volume charge density of the second electrically charged portion, thereby enhancing CD8(+) T-cell response and higher antibody titer after administrating an organism with the immunostimulatory nanocomplex.
