    Description / Table of Contents: Zusammenfassung Der Umsatz von Xanthobilirubinsäuremethylester mit Brom in Methanol ergibt in 20-prozentiger Ausbeute ein rotes Pigment, für das die bislang nicht bekannte 16,24-Dehydrobiladien-ab-Konstitution abgeleitet wurde. Darüber hinaus konnte das entsprechende Mesobiliverdin-XIIIα, Mesobilirubin-XIIIα, 14-Formyltripyrrinon, und zwei diastereomere 15,16-Dimethoxybiladiene-ab aus der Reaktionsmischung isoliert werden. Die mechanistischen Aspekte dieser Reaktion werden diskutiert.
    Notes: Summary On treating xanthobilirubic acid methyl ester with bromine in methanol, a red bile pigment, which was assigned the hitherto unknown 16,24-dehydrobiladiene-ab constitution, is obtained in 20% yield. In addition, the corresponding mesobiliverdin-XIIIα, mesobilirubin-XIIIα, 14-formyl-tripyrrinone, and two diastereomeric 15,16-dimethoxybiladienes-ab could be isolated from the reaction mixture. The mechanistic aspects of this reaction are discussed.

    The third fundamental form metric for hypersurfaces in nonflat space forms (1999)
    Springer
    Journal of geometry 65 (1999), S. 130-142 
    Details
    ISSN: 1420-8997
    Keywords: 53 B 25 ; 53 C 42 ; 53 C 25 ; third fundamental form metric ; hypersurfaces in nonflat space forms ; Einstein metric ; Codazzi tensor ; isoparametric hypersurfaces

    Notes: Abstract For hypersurfaces with regular Weingarten operator in nonflat space forms we study the relations between the intrinsic geometry of the third fundamental form metric and the extrinsic geometry of the hypersurface. We prove a theorema-egregium-type result for this metric and, in particular, give a local classification of hypersurfaces in case of an Einstein structure of this metric.

    The use of augmented-pressure colostography in imperforate anus (1997)
    Springer
    Pediatric surgery international 12 (1997), S. 383-385 
    Details
    ISSN: 1437-9813
    Keywords: Key words Colostogram ; Imperforate anus ; Anorectal malformation

    Topics: Medicine
    Notes: Abstract Colostomy is recommended in most newborns with imperforate anus (IA), except those with low-type anorectal malformations (ARM). Accurate demonstration of the anatomy of any associated fistula between the rectum and the urogenital tract is essential for optimal surgical management. Augmented-pressure distal colostography is recommended to fulfill this requirement prior to definitive surgical repair of IA. We examined 12 cases of high or intermediate-type ARM using this technique, which clearly demonstrated the distal perineal anatomy. All were confirmed at posterior sagittal anorectoplasty.
