Abstract: The present invention relates to a functionally expressed bacterial voltage-sensitive ion-selective channel. The novel channel can be used in conjunction with mammalian ion channel pore-containing regions in assays for screening for compounds that modulate activity of the channel. One bacterial ion channel of the present invention, called NaChBac, is derived from Bacillus halodurans (GenBank#BAB05220 (8)).

Abstract: Nucleic acid and protein sequences relating to a cation channel which is sperm-specific (CatSper2) are disclosed. The CatSper2 protein is shown to be specifically expressed in sperm. Nucleic acids, vectors, transformed cells, transgenic animals, polypeptides, and antibodies relating to the CatSper2 gene and protein are disclosed. Also provided are methods of in vitro fertilization and contraception, methods of identifying modulators of CatSper2 activity, methods of genotyping subjects with respect to CatSper2, methods of diagnosing and treating CatSper2-mediated disorders, including infertility, as well as methods of doing business related to CatSper2-mediated disorders.

Abstract: Methods for identifying neuroprotective compounds, as well as compositions and methods for treating subjects suffering from neurological diseases or disorders are provided.

Abstract: The succinate and napadisylate salts and solvates of 2-(Methyloxy)-N-[2-methyl-1-phenyl-2-(1-pyrrolidinyl)propyl]-4,6-bis(trifluoromethyl)benzamide, 6-bis(trifluoromethy)benzamide napadisylate, and uses thereof in the treatment of disorders relating to GlyT1 transporter, such as schizophrenia, are disclosed.

Abstract: The present invention relates to novel salts of 7-[4-(4-chlorobenzyloxy)benzenesulfonyl]-8-methoxy-3-methyl-2,3,4,5-tetrahydro-1H-3-benzazepine and a pharmaceutically acceptable solvate thereof, pharmaceutical formulations, processes for their preparation, and their use in medicine. The chemical entities are useful in therapy, in particular as antipsychotic agents.

Related business methods are also disclosed.

Abstract: The invention provides nanosensors and nanosensor components for the detection of ion channel activity, receptor activity, or protein protein interactions. Certain of the nanosensor components comprise a nanoparticle and recognition domain. Following contact with cells and, optionally, internalization of the nanosensor component by a cell, the recognition domain binds to a target domain, e.g., a heterologous target domain, of a polypeptide of interest such as an ion channel subunit, G protein coupled receptor (GPCR), or G protein subunit. Ion channel activity, GPCR activity, or altered protein interaction results in a detectable signal. The nanoparticles may be functionalized so that they respond to the presence of an ion by altering their proximity. Certain of the nanosensors utilize the phenomenon of plasmon resonance to produce a signal while others utilize magnetic properties, RET, and/or ion-sensitive moieties. Also provided are polypeptides, e.g.

Abstract: The present invention provides methods and compositions for expressing eukaryotic membrane proteins.

Abstract: A remotely controlled submersible vehicle comprises a fore section and an aft section. In use, they are held apart from each other, such as by telescopic arms, in order to define a gap within which a payload is received. This keeps the payload near the center of the vehicle, improving the balance of the vehicle and minimizing any threat of disruption to the wash path of thrusters.
