    Vasoactive intestinal peptide (VIP) cells in the pancreas and gastro-intestinal mucosa (1977)

    Notes: Summary Using antibodies against pure porcine VIP in immunoperoxidase and immunofluorescence tests, VIP-immunoreactive cells have been detected in the pancreas—especially in the islets—and gastrointestinal mucosa of the dog, guinea-pig and man. VIP immunoreactive cells were widely distributed in these tissues, never being numerous at any site. Some parallelism has been noted between such cells and ultrastructurally identified D1 cells of the pancreas and gastrointestinal mucosa. The presence of VIP cells in normal pancreas may help explain the occurrence of pancreatic endocrine tumors producing VIP.

    Salivary amino acids and proteins in normal and malnourished Egyptian infants and young children (1978)
    Springer
    European journal of nutrition 17 (1978), S. 19-25

    Description / Table of Contents: Zusammenfassung Der Gehalt an Aminosäuren und Proteinen im Speichel von normalen und unterernährten ägyptischen Kindern und Kleinkindern wurde untersucht. 16 Aminosäuren, davon 7 essentielle konnten im Speichel von normal ernährten Kindern nachgewiesen werden. Die elektrophoretische Analyse ergab den Nachweis von 10 Proteinen im Speichel von normalen und unterernährten Kindern. Bei ödematösen Kindern nimmt der Gehalt sowohl an Aminosäuren, besonders der essentiellen, als auch an Proteinen zu. Bei nicht ödematösen Fällen waren der Gehalt und die Zusammensetzung mehr oder weniger normal, aber bei Marasmus dritten Grades sind Aminosäuren und Proteine etwas vermehrt. Aus diesen Ergebnissen wird geschlossen, daß die Zunahme des Speichelgehaltes an Aminosäuren und Proteinen bei unterernährten ödematösen Kindern infolge einer Gewebsdegeneration ausgelöst wird, welche bei der nicht ödematösen Form der Krankheit weniger ausgeprägt ist.
    Notes: Summary Amino acids and proteins in whole saliva of normal and malnourished Egyptian infants and young children were investigated. 16 amino acids, 7 of them are essential, could be detected in saliva of normal infants. Electrophoretic analysis revealed the existence of 10 protein components in saliva of either normal or malnourished infants. In oedematous cases, salivary amino acids, particularly the essential ones, were increased as well as most of the protein components. In non-oedematous cases, the pattern was more or less normal, but in 3rd grade marasmus, amino acid and protein components of saliva were somewhat increased. The conclusion was drawn that such increase is mainly due to tissue degeneration which is more marked in oedematous than non-oedematous form of the disease.

    Characteristic protein electrophoretic patterns of fourEntamoeba strains (1978)

    Notes: Summary Total proteins from trophozoites of four axenized strains of the histolytica group ofEntamoeba (twoE. histolytica, oneE. invadens, and oneE. moshkovskii) were analyzed by disc-electrophoresis in polyacrylamide sodium dodecyl sulphate slab gels and by radial immunodiffusion. Each strain had a characteristic and reproducible electrophoretic pattern with about 30 major protein bands distributed between molecular weights 12,000 and 110,000. A striking similarity was found between the protein patterns of bothE. histolytica strains. Immunodiffusion also resulted in characteristic patterns, in which the greatest resemblance occurred in the same strains. The sensitivity and high resolution of the electrophoretic method for protein analysis and its correlation with antigenic characterization suggests its use as a taxonomic criterion of the histolytica group of the genusEntamoeba.

    Morphology of the spermatid and spermatozoon of Amblyomma hebraeum Koch (Acarina; Ixodidae) (1978)
    Springer
    Parasitology research 55 (1978), S. 91-99 
    Details
    ISSN: 1432-1955
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary Spermatids and spermatozoa of Amblyomma hebraeum were examined by scanning and transmission electron microscopy as well as by freeze-etch and freeze-fracture techniques. The external surface of the spermatid is smooth except for a rim of two parallel grooves near the anterior apex. This rim probably marks the level at which a cap detaches, permitting extrusion of the inner cord during spermatozoon maturation. Both ends of the spermatid are closed, the anterior part being slightly thicker than the posterior. The spermatozoon is clavate anteriorly and tail-like posteriorly. The tip of the anterior part is a hemispherical structure carrying numerous bulbous expansions. Apart from the hemishperical structure, the entire spermatozoon surface is covered with parallel longitudinal cellular processes. Waves of constrictions on the tail-like part of the spermatozoon and undulations of the cellular processes are considered to be involved in sperm motility.

    Different secretory responses of periinsular and other acini in the rat pancreas after pilocarpine injection (1975)
    Springer
    Cell & tissue research 161 (1975), S. 133-143 
    Details
    ISSN: 1432-0878
    Keywords: Pancreas (rat) ; Halo phenomenon, pilocarpine ; Influence of insular hormones ; Histochemistry and electron microscopy
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary Histological, histochemical, and electron microscopical investigations of the rat pancreas, one to five hours after pilocarpine injection (4 mg in 1 ml normal saline solution), showed different secretory responses in periinsular and apoinsular acinar cells. The responsiveness to parasympathetic stimulation is markedly retarded and weakened in the periinsular area. It is supposed that the halo phenomenon is related not only to an inhibition of the secretion, but also to a longer lasting synthesis of zymogen granules. The insular hormones, glucagon and insulin, which are possibly locally enriched by insulo-acinar capillary anastomoses or by diffusion, may be involved in the regulation of activity in the periinsular cells.

    Large displacement analysis of three-dimensional beam structures (1979)

    Notes: An updated Lagrangian and a total Lagrangian formulation of a three-dimensional beam element are presented for large displacement and large rotation analysis. It is shown that the two formulations yield identical element stiffness matrices and nodal point force vectors, and that the updated Lagragian formulation is computationally more effective. This formulation has been implemented and the resulted of some sample analyses are given.
