    Notes: 13C NMR data for several 1-substituted prop-2-ynes and 1,4-bis derivatives of but-2-yne are reported with full assignments. Substituent effects of  - X - aryl groups (X = O, S, NMe, SO2) at the propargylic position on the chemical shifts of the acetylenic carbons were determined.

    An explicit formulation of a triangular plate-bending element with shear (1992)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: Plate-bending elements with the inclusion of transverse shear effects are important in analysing problems of transverse bending of relatively thick plates. Several such elements are available. Recently another element with a triangular geometry has been suggested. The construction of the element stiffness matrix follows conventional procedure which involves rigorous matrix computations. An alternative method of obtaining the stiffness matrix explicitly for such an element is suggested in the present work. Thus the process of matrix inversion and a considerable degree of matrix multiplications can be avoided in constructing the element stiffness matrix. Explicit expressions worked out may be conveniently used in microcomputers.

    A Convenient Synthesis of Centperazine, an Antifilarial Candidate Drug (1993)
    Weinheim : Wiley-Blackwell

    Notes: 7-Ethyl-octahydro-2-methyl-6H-pyrazino[1,2-c]pyrimidin-6-one (centperazine) (1), an antifilarial candidate drug, currently undergoing phase II clinical trials, has been synthesized by a more economically viable alternative route. Condensation of N,N′-dibenzylethylenediamine (2) with 3,4-dibromobutyronitrile (3) gives 2-(1,4-dibenzyl-2-piperazinyl)acetonitrile (4), which, on catalytic reduction, debenzylation, cyclocarbamation and N-alkylation yields the target molecule 1 in 10.1% overall yield.

    The 87-kD A gamma-globin enhancer-binding protein is a product of the HOXB2(HOX2H) locus (1994)
    American Society of Hematology
    Details
    Publication Date: 1994-03-01
    Description: Developmental regulation of globin gene expression may be controlled by developmental stage-specific nuclear proteins that influence interactions between the locus control region and local regulatory sequences near individual globin genes. We previously isolated an 87-kD nuclear protein from K562 cells that bound to DNA sequences in the beta- globin locus control region, gamma-globin promoter, and A gamma-globin enhancer. The presence of this protein in fetal globin-expressing cells and its absence in adult globin-expressing cells suggested that it may be a developmental stage-specific factor. A lambda gt11 K562 cDNA clone encoding a portion of the HOXB2 (formerly HOX2H) homeobox gene was isolated on the basis of the ability of its beta-galactosidase fusion protein to bind to the same DNA sequences as the 87-kD K562 protein. Because no other relationship had been established between the 87-kD K562 protein and the HOXB2 protein other than their ability to bind ot the same DNA sequences, we have investigated whether the two proteins are related antigenically. Our data show that antisera produced against the HOXB2-beta-gal fusion protein and a synthetic HOXB2 decapeptide react specifically with an 87-kD protein from K562 nuclear extract, showing that the 87-kD K562 nuclear protein is a product of the HOXB2 locus, and is the first demonstration of cellular HOXB2 protein.
