Abstract: Provided herein are compositions, combinations, and methods comprising NMDA antagonists including, but not limited to, NMDA glutamate receptor antagonists such as [2-(8,9-dioxo-2,6-diazabicyclo[5.2.0]non-1-(7)-en-2-yl)alkyl]phosphonic acid and derivatives thereof, which are effective in reducing the amount of anesthetic required to maintain anesthesia (i.e. to achieve an anesthetic-sparing effect).

Abstract: Disclosed are novel DNAs encoding polypeptides related to opioid receptors, methods for expressing and isolating such polypeptides, and methods of use thereof. Also disclosed are vectors for expressing the novel DNAs of the invention.

Abstract: Isolated DNAs encoding opiorph receptor polypeptides are provided. Recombinant cloning vectors which include these DNA sequences and cells which include these vectors are also provided. Methods for detecting the expression, in a tissue, of mRNA encoding a polypeptide encoded by this DNA are encompassed as well as methods for producing these polypeptides. These isolated polypeptides and antibodies to these polypeptides are also contemplated.

Abstract: Growth hormone releasing hormone (GHRH) receptor binding has been characterized using a unique binding assay utilizing iodinated GHRH probes. Photoaffinity GHRH probes have been constructed which allow for photolabeling and characterization of the receptor. In addition, high affinity biotinylated GHRH analogs have been constructed. Solubilization of GHRH-R/GHRH complexes and extraction of specifically bound GHRH using a mild detergent solution, followed by affinity chromotography, leads to a substantially purified GHRH-R isolate. Electrophoretic treatment of the GHRH-R isolate produces GHRH-R of sufficient purity to conduct sequencing of the receptor.
