Abstract: A therapeutic method for the treatment of Crohn's disease is provided, comprising administering to a patient in need of said treatment an intravenous dose of azathioprine or a pharmaceutically acceptable derivative thereof.

Abstract: The present invention provides a method to increase the susceptibility of cultured Zea mays cells to stable transformation with recombinant DNA via electroporation, by pretreating the Zea mays cells with certain pectin-degrading enzymes, so that the cells retain their ability to regenerate fertile, transgenic Zea mays plants containing the DNA which is also heritable.

Abstract: The present invention provides a method for the selective cleavage of peptide amide bonds under ambient conditions by treating a peptide comprising the subunit --CO--NH--CH((CH.sub.2).sub.x SY)CONH-- wherein x is 1-2 and Y is H or (C.sub.1 -C.sub.4)alkyl in an aqueous medium with a tetracoordinate Pd(II) or tetracoordinate Pt(II) complex which promotes the hydrolysis of the adjacent amide bond proximal to the carboxy terminus of the subunit.

Abstract: A motion provided to alleviate the tolerance to, or dependence on, an opiate analgesic, by the administration of an effective amount of a selective delta opioid receptor antagonist to a human patient in need of such treatment.

Abstract: Carbon-clad zirconium oxide particles are disclosed which are useful in sorbent applications, particularly as packing materials for High Performance Liquid Chromatography (HPLC). A method for the preparation of chromatographic support material is also disclosed which utilizes low pressure.

Abstract: A method of measuring adenylate cyclase (AC) in a sample of physiological material which does not employ radioactive reagents is provided, comprising:(a) providing a physiological sample of physiological material comprising cAMP produced by endogenous AC, and other endogenous adenine nucleotides selected from the group consisting of ATP, AMP, ADP and mixtures thereof;(b) combining the sample with effective amounts of apyrase, 5'-nucleotidase and adenosine deaminase, so as to enzymatically eliminate the other endogenous adenine nucleotides in the sample;(c) enzymatically converting the cAMP into AMP; and(d) measuring the amount of AMP, the amount providing a measure of the amount of cAMP and AC in the sample.

Abstract: A method is provided for forming films comprising Fe, Ru or Os employing the techniques of chemical vapor deposition to decompose a vapor comprising an organometallic compound of the formula (a): (CO).sub.4 ML or (b): M.sub.2 [.mu.-.eta.:.eta..sup.4 -C.sub.4 ](CO).sub.6 ; wherein L is a two-electron donor ligand and each R is H, halo, OH, alkyl, perfluoroalkyl or aryl; so as to deposit a coating comprising one or more of said metals on the surface of a substrate.

Abstract: The present invention relates to a voltammetric sequence-selective sensor for target polynucleotide sequences which essentially comprises: an immobilized polynucleotide probe having one end covalently bound onto an amperometric electrode. The immobilized probe includes a target binding region capable of hybridizing to the target polynucleotide sequences forming an immobilized heteroduplex having at least a hybridized region. The sequence-selective sensor of the present invention also comprises means for voltammetrically detecting immobilized heteroduplexes. There is also provided a method for detecting the presence of a target polynucleotide analyte in a physiological sample, which comprises the steps of incubating the prepared physiological sample with the voltammetric sequence-selective sensor of the present invention; voltammetrically detecting immobilized heteroduplexes; and comparing the resulting voltammogram with a control voltammogram.

Abstract: Cyclophosphamide analogs are provided of the general formula: ##STR1## wherein R.sup.1 and R.sup.2 are each (C.sub.2 -C.sub.6)alkyl, substituted with a leaving group such as halo or alkylsulfonyl, R.sup.3 and R.sup.4 are the same as R.sup.1 and R.sup.2 or are H and Ar is a heteroaromatic ring and the pharmaceutically acceptable salts thereof.
