The present invention provides assays and assay systems for use in spatially encoded biological assays. The invention provides an assay system comprising an assay capable of high levels of multiplexing where reagents are provided to a biological sample in defined spatial patterns; instrumentation capable of controlled delivery of reagents according to the spatial patterns; and a decoding scheme providing a readout that is digital in nature.

Ablation device for creating a lesion within tissue includes an angle indexing apparatus. The angle indexing apparatus includes an index-key and an indexer. The index-key is secured to the ablation device. The indexer is secured in a position relative to which the index-key can move. The index-key is adapted to mate with the indexer in a plurality of positions, thereby allowing operation of the ablation device in a plurality of orientations.

Process for making a functionalized substrate in the form of a water-soluble film carrying a coating of a functional composition, the process comprising applying to at least one side of the film an aqueous solution comprising one or more functional materials to form the coating wherein the coating is formed from a plurality of layers in a stepwise manner and / or the aqueous solution comprises a film insolubilizer agent.

Systems providing improved methods of performing a spinal fusion procedure and including a monorail instrument that protects the medial neural structures, includes a sliding platform for additional instrumentation and allows controlled delivery of various instruments for disc preparation and implant insertion. The monorail instrument engages other instruments, including various instruments utilized to prepare the disc space as well as spinal fusion implants, for guided and controlled insertion into the disc space. The monorail instrument may be a distractor, and may include flutes for preparation of the disc space.

The present invention relates to antisense antiviral compounds and methods of their use and production in inhibition of growth of viruses of the Orthomyxoviridae family and in the treatment of a viral infection. The compounds are particularly useful in the treatment of influenza virus infection in a mammal. Exemplary antisense antiviral compounds are substantially uncharged, or partially positively charged, morpholino oligonucleotides having 1) a nuclease resistant backbone, 2) 12-40 nucleotide bases, and 3) a targeting sequence of at least 12 bases in length that hybridizes to a target region selected from the following: a) the 5′ or 3′ terminal 25 bases of the negative sense viral RNA segment of Influenzavirus A, Influenzavirus B and Influenzavirus C; b) the terminal 30 bases of the 5′ or 3′ terminus of the positive sense vcRNA; c) the 45 bases surrounding the AUG start codon of an influenza viral mRNA and; d) 50 bases surrounding the splice donor or acceptor sites of influenza mRNAs subject to alternative splicing.

The subject invention provides compounds having the structure: wherein R1 is substituted or unsubstituted phenyl or a 5-6 membered heterocyclic or heteroaromatic ring containing from 1 to 5 heteroatoms; R2 is hydrogen, or a substituted or unsubstituted alkyl, —C(O)-alkyl, —C(O)—O-alkyl, alkoxy, cycloalkyl, alkenyl, monocyclic or bicyclic aryl, heteroaryl or heterocyclic moiety; R3 is hydrogen, or a substituted or unsubstituted alkyl, —C(O)-alkyl, —C(O)—O-alkyl, alkoxy, cycloalkyl, alkenyl, monocyclic or bicyclic aryl, heteroaryl or heterocyclic moiety, or R2 and R3 are joined to form a heterocyclic ring; wherein the dashed line represents a second bond which may be present or absent, and when present R3 is oxygen; R4 and R5 are each independently substituted or unsubstituted alkyl, —C(O)-alkyl, —C(O)—O-alkyl, alkoxy, cycloalkyl, alkenyl, monocyclic or bicyclic aryl, heteroaryl or heterocyclic moiety, or R4NR5 together form a substituted or unsubstituted monocyclic or bicyclic, heterocyclic or heteroaryl moiety containing from 1 to 6 heteroatoms; R12 is hydrogen, alkyl, halogen or cyano; and n is 0, 1, 2, 3 or 4, or an enantiomer, or a specific tautomer, or a pharmaceutically acceptable salt thereof and a method for treating a disease associated with the A2b adenosine receptor by administering a therapeutically effective amount of the compounds of the invention.

The present invention provides a simple and improved osmotic device that is capable of providing a controlled release of active agent contained in the core first through a preformed passageway and then through an in situ formed second passageway into an environment of use. One or both of the passageways optionally increases in size during use of the osmotic device. The preformed passageway and / or the second passageway increase the release rate of the active agent, enable the release of large particles containing active agent, and / or enable the release of active agents that are substantially insoluble in the environment of use. By virtue of the in situ formation of the second aperture, the device is able to release a greater overall percentage of active agent than it would release in absence of the second aperture.
