Abstract: A method of producing analgesia in nociceptive and neuropathic pain is disclosed. The method includes administering to a subject an omega conopeptide which is characterized by its ability to (a) inhibit electrically stimulated contraction of the guinea pig ileum, and (b) bind selectively to omega conopeptide MVIIA binding sites present in neuronal tissue. Also disclosed are novel omega conotoxin peptides effective in producing analgesia.

Abstract: A biosensor apparatus for detecting a binding event between a ligand and receptor. The apparatus includes an electrode substrate coated with a high-dielectric hydrocarbon-chain monolayer, and having ligands attached to the exposed monolayer surface. Binding of a receptor to the monolayer-bound ligand, and the resultant perturbation of the monolayer structure, causes ion-mediated electron flow across the monolayer. In one embodiment, the monolayers have a coil-coil heterodimer embedded therein, one subunit of which is attached to the substrate, and the second of which carries the ligand at the monolayer surface.

Abstract: A method and comjugate for treating H. pylori infection in a subject are disclosed. The conjugate is composed of (a) a nuclease-resistant antisense oligomer effective to inhibit H. pylori infection in the subject by base-specific Watson-Crick binding to an H. pylori mRNA transcript, and (b) a transport moiety conjugated to the oligomer. The transport moiety is effective to facilitate uptake of the conjugate from the environment of the stomach into the cytoplasm of H. pylori cells by active transport or by pH-gradient transport across of the cell membrane of H. pylori. The conjugate is administered by oral route, preferably in a swellable polymer bolus designed to release the conjugate in sustained release.
