    Polymerization to graphite-like nitride clusters from tetracyanoethylene vapor (1994)
    Woodbury, NY : American Institute of Physics (AIP)

    Notes: Various types of graphite-like nitride clusters were synthesized by chemical vapor deposition of tetracyanoethylene (TCE) onto a substrate of cleaved KCl crystals at 230–300 °C. At a low reaction temperature of 230 °C, TCE was polymerized to ribbon-like clusters, which resembled curved graphitic sheets. Upon increasing the reaction temperature to 250–300 °C, polymerized TCE condensed on KCl to form spheric clusters. The most regular structure of the clusters was obtained at 300 °C in a nanoscale needle-like morphology. High-resolution electron microscopy suggested that these clusters were composed of polymerized TCE layers with a interlayer distance of 0.34–0.35 nm. © 1994 American Institue of Physics.

    Epitaxial growth of C60 and KI(001) surface (1994)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 65 (1994), S. 1222-1223 
    Details
    ISSN: 1077-3118

    Topics: Physics
    Notes: Epitaxial growth of C60 is observed for vacuum-deposited crystals on the KI(001) cleavage surface. When the KI surface is kept at 240 °C and the deposition rate is controlled to be less than a monolayer min−1 (∼0.5 nm min−1), rectangular platelike crystals of C60 grow epitaxially. Transmission electron micrographs and electron diffraction patterns of the crystals exhibit that the (002) planes of the face-centered cubic C60 crystal orient in parallel to the KI(001) surface. This epitaxial orientation is explained in terms of thec(2×2) commensurate lattice matching.

    Transitory elevation of serum amylase levels after restorative proctocolectomy (1992)

    Description / Table of Contents: Résumé L'incidence d'une hyperamylasémie post-opératoire a été étudiée chez 70 malades qui ont subi une proctocolectomie restaurative en plusieurs temps. Le 14ème jour post-opératoire, 27 des 70 patients après colectomie totale montraient une hyperamylasémie, et l'amylase sérique retournait à la normale au 30ème jour post-opératoire. 3 des 37 après anastomose iléo-anale et 8 des 70 après fermeture de la stomie montraient une élévation de l'amylase sérique post-opératoire. La colectomie totale pourrait avoir un possible rôle dans l'augmentation post-opératoire de l'amylase sérique. Aucun de ces patients n'avaient eu une évidence clinique certaine de pancréatite post-opératoire. Chez 7 malades montrant une élévation significative des taux d'amylase sérique (au dessus de 1000 IU) ceci était dû surtout à l'isoenzyme pancréatique. Cette élévation transitoire de l'amylase sérique semblait n'être pas modifiée par l'administration d'agents thérapeutiques pour la pancréatite. Ces observations suggèrent que l'hyperamylasémie post-opératoire sans évidence clinique de pancréatite est très commune après colectomie totale et que l'hyperamylsémie post-opératoire elle-même ne require pas nécessairement un traitement.
    Notes: Abstract The incidence of postoperative hyperamylasaemia was evaluated in 70 patients who underwent staged restorative proctocolectomy. On the 14th postoperative day, 27 of 70 patients after total colectomy showed hyperamylasaemia, and the serum amylase returned to normal on the 30th postoperative day. Three out of 37 after ileoanal anastomosis and 8 out of 70 after stoma closure showed elevation of serum amylase postoperatively. Total colectomy might have a possible role in the postoperative increase of serum amylase. None of these patients had any obvious clinical evidence of postoperative pancreatitis. In 7 patients showing significant elevation of serum amylase levels (over 1000 IU), this was due predominantly to the pancreatic isoenzyme. This transitory elevation of serum amylase did not seem to be altered by the administration of therapeutic agents for pancreatitis. These observations suggest that postoperative hyperamylasaemia without clinical evidence of pancreatitis is very common after total colectomy, and that postoperative hyperamylasaemia itself does not necessarily require treatment.
