    Notes: Summary High molecular weight mouse nerve growth factor(H M W-NGF), in addition to its effects on certain neural elements, is also chemotactic for human polymorphonuclear leukocytes. One of the subunits of H M W-NGF is a protease of the serine family and its active site contains a serine residue and a closely-neighboring histidine residue that are both essential for proteolysis. Elimination of enzyme activity by irreversibly blocking the single serine has no effect on leukotaxis, but blocking the histidine abolishes leukotaxis. These results suggest the possibility that part of the proteolytic active site of this enzyme may have evolved to perform more than one, completely different, biologic function — proteolysis as well as nonproteolytically mediated chemotaxis.

    Food habits of the giant humphead wrasse,Cheilinus undulatus (Labridae) (1978)
    Springer
    Environmental biology of fishes 3 (1978), S. 235-238

    ISSN: 1573-5133
    Keywords: Coral reef fishes ; Indo-Pacific ; Stomach contents ; Oceania ; Red Sea

    Topics: Biology
    Notes: Synopsis The giant humphead wrasse (Cheilinus undulatus), an inhabitant of coral reefs, is widely distributed in the tropical Indo-Pacific region. Stomach and intestinal contents of 72 specimens from the Pacific and the Red Sea revealed that this fish feeds primarily on mollusks, fishes, echinoids, and crustaceans.

    Eine neuartige Methode der Kompensation unspezifischer Lichtverluste in der Atomabsorptions-Spektroskopie (1974)

    Description / Table of Contents: Zusammenfassung Es wird ein neuartiges System zur Kompensation unspezifischer Lichtverluste in der Atomabsorptions-Spektroskopie beschrieben. Dieses System hat folgende typische Eigenschaften: Es arbeitet im Zweistrahlbetrieb und gestattet die Ermittlung der unspezifischen und spezifischen Lichtverluste im gleichen Bereich der Atomzone. Sowohl sehr schnell veränderliche, als auch sehr hohe unspezifische Lichtverluste (bis zu mindestens 1,0 Extinktionseinheiten) können kompensiert werden. Als Anwendungsbeispiele werden die Bestimmung von Blei in Kondensmilch und in aufgeschlossenen Blutproben diskutiert.
    Notes: Abstract A new system is described with particular attention being given to the characteristic features: it works in the double beam mode and allows the determination of non-specific and specific losses of light in the same area of the atomic zone; a reliable compensation may be accomplished for quickly varying as well as for high non-specific losses of light (up to at least 1.0 absorbance units). The determinations of lead in condensed milk and in digested blood are discussed as typical examples for the application of the system.
