Abstract:
A method and apparatus for vacuum arc deposition of material on a surface of an object (32), uses a vacuum chamber (12) accomodating the active surface of the cathode (24) and an anode (34). A power supply connected to the anode (34) and cathode (24) establishes an electric arc. The track of the arc is controlled with a magnetic field established with a permanent magnet (56) that is moved in a closed path relative to the cathode. A solenoid (68) modifies the main magnetic field produced on the active surface of the cathode (24).
Abstract:
The invention relates to consolidated ligands, which include amino acid sequences which bind to at least two domains of a target protein. The consolidated ligands have increased affinity for the target protein over ligands directed to a single domain. Particularly preferred ligands include those directed to the Src Homology 2 and 3 (SH2, SH3) domains of eukaryotic protein tyrosine kinases, which are involved in complex regulation of the enzymic activity, obligatory for differentiation and growth control. Ligands of this kind of design may be widely useful as reagents in the investigation of SH interactions, and as leads for design of therapeutic agents.

Abstract:
The present invention provides a series of ibogaine analogs of formula (I) wherein: R1 is S or O; R2 is H, (C1-C4)alkyl, (C1-C4)alkoxy, OH, CN, CONH2, halo, oxazolyl, (C1-C4)alkylS, or (C1-C2)trifluoroalkyl; R3 is a phenyl group optionally substituted at the 2'- or 3'-position of the phenyl ring with halo, N(R)2, wherein each R is H or (C1-C4)alkyl; or NO2; and R4 is (C3-C6)cycloalkyl(C1-C4)alkyl, (C3-C6)cycloalkyl or (C1-C4)alkyl, optionally containing 1-2 double bonds, and the pharmaceutically acceptable salts thereof, useful to treat cocaine addiction and the use of other addictive substances.
Abstract:
The invention provides certain amino acid conjugates of substituted 2-phenyl-N-[1-(phenyl)-2-(1-heterocycloalkyl- or heterocycloaryl-)ethyl]acetamides useful for selectively agonizing kappa opioid receptors in mammalian tissue.
Abstract:
A method for identifying an immunodominant sequence region in a diphtheria toxin-specific peptide is provided. Also provided are diphtheria toxin-specific peptides with an immunodominant sequence region.
Abstract:
The invention is directed to methods of culturing rickettsiae in Ixodes scapularis cell lines. The methods of the invention provide for culture of microorganisms such as Anaplasma marginale, Ehrlichia canis, and Rickettsia rickettsii. A method of the invention involves incubating a rickettsia with an Ixodes scapularis tick cell culture in a culture medium under reduced oxygen and increased CO2 at a sufficient temperature until growth of the rickettsia is detected. The culture medium comprises a medium suitable for the growth of invertebrate cells supplemented with an organic buffer. The cell culture method can be used in large scale production of rickettsia containing products useful in diagnostic assays and vaccine preparations.
