    SUBCELLULAR DISTRIBUTION AND TRANSPORT OF ACETYLCHOLINE IN CAT VENTRAL ROOTS AND SCIATIC NERVE (1978)

    Notes: Abstract— The axonal transport of radioactive ACh, which was labelled by injecting radioactive choline into the ventral horn of the cat, was studied. Radioactivity analysed as ACh was transported in the nerves at a rate of 20–25 cm/24 h from the place of injection. Morphological and biochemical analysis after density gradient centrifugation revealed that endogenous ACh was principally distributed in three fractions-(a) a soluble fraction (provided homogenization was carried out in the presence of eserine), (b) a vesicular fraction (diameter 600–1600 A) in the 0.4M-sucrose layer of the density gradient, and (c) a fraction containing very small structures (size 90–100 A) in the 0.8–1.0 M-sucrose interphase. The radioactive ACh, however, was exclusively found in the soluble fraction (supernatant) after density gradient centrifugation. Analysis of ACh metabolites showed that radioactive ACh may have been formed locally in the nerves after transport of its precursor. Thus the morphologic and metabolic results do not support the hypothesis that ACh is transported in vesicles.

    THE RELATIONSHIP OF CARDIAC SHEAR AND TRACE ELEMENT CONTENT TO BEEF MUSCLE TENDERNESS (1976)

    Notes: The purpose of this investigation was to determine whether mechanical shear values of the cardiac muscle could be useful in predicting skeletal muscle tenderness as measured by mechanical shear and sensory evaluation methods. The metal ion content of bovine skeletal muscle was also determined and evaluated for its ability to predict skeletal muscle tenderness. W-B shear results indicate cardiac muscle tenderness is related to semimembranosis tenderness, but the magnitude of the correlation coefficient is not high enough for adequate prediction capabilities. However, the predictive capability of element content is very good for all three tenderness measures-sensory panel, W-B and rotary shear. These results indicate the good potential of this approach to tenderness prediction.

    Notes: [Auszug] The lower crust of the neutron star contains fat nuclei bathed in a neutron Fermi gas which is almost surely super-fluid5. The discussions we have found of this superfluid do not observe that its Tc and energy gap will at most densities be determined by the proximity effect from those of the ...

    Description / Table of Contents: Zusammenfassung In dieser Arbeit diskutieren wir die rechnerischen Gesichtspunkte zweier Algorithmen von E. I. Jury zur Entscheidung ob alle Nullstellen eines Polynoms mit ganzzahligen Koeffizienten im Einheitskreis liegen. Wir zeigen, daß beim ursprünglichen Algorithmus von Jury die Rechenzeit asymptotisch exponentiell mit dem Grad des Polynoms anwächst, wenn mit variable Genauigkeit gerechnet wird. Wir zeigen auch, daß unter denselben Voraussetzungen beim modifizierten Algorithmus von Jury die Rechenzeit durch eine Potenz vom Grad des Polynoms abgeschätzt werden kann. Schließlich geben wir einen auf Kongruenzen beruhenden, zum modifizierten Algorithmus von Jury analogen Algorithmus an, der aber weniger Rechenzeit als dieser benötigt.
    Notes: Abstract In this paper we discuss the computational aspects of two algorithms due to E. I. Jury for determining if all the zeros of a polynomial with integer coefficients lie within the unit circle. We show that Jury's original algorithm asymptotically requires an exponential amount of computing time when variable-precision arithmetic is employed. We show that his modified algorithm requires only a polynomially bounded amount of computing time when variable-precision arithmetic is employed. Finally we produce a congruence arithmetic algorithm analogous to Jury's modified algorithm which requires less computing time than Jury's modified algorithm.

    Notes: Conclusion These studies on isolated intact mast cell granules, indicate that changes in the concentration of the divalent cations (Ca2+, Mg2+)alone cannot explain the membrane fusions and histamine release during sequential exocytosis in mast cells.

    Changes in production, yield, and chemical composition of corn(Zea mays) after ultrasound treatments of the seeds (1979)

    Notes: Summary In the spring of each year (1972–1974) air-dry grains of two inbred lines ofZ. mays (7275-13-1 and 106) were exposed for 17 h to a low level (25 kHz) of ultrasound and subsequently planted in the field together with untreated controls and grown to maturity. In the fall of each year the ears of each group were harvested and the number of broken stalks, the yield and weight of grains and grain parts and the alcohol-soluble amino acid complement of the grain parts were determined. Broken stalks and yields were unaffected, however the embryos from the treated groups retained more moisture than their respective controls, dry weights were also significantly increased. The alcohol-soluble amino acid composition of the embryos was markedly changed, levels of proline were severely depressed in the embryos of both lines and generally increased in the endosperms. Sonication resulted in an overall decrease of up to 40% in totalled alcohol-soluble amino acids in the grains of 7275-13-1.

    The role of calcium ions in the synthesis and transport of noradrenaline carrier vesicles in guinea-pig sympathetic neuronsin vitro (1978)

    Notes: Summary Guinea-pig inferior mesenteric ganglia (IMG)/hypogastric nerve preparations were incubated in tissue culture media containing ethylene glycol-bis-(β-aminoethyl ether)N,N′tetra-acetic acid (EGTA) or colchicine and examined either by fluorescence microscopy or by transmission electron microscopy. Two millimolar EGTA inhibited the accumulation of noradrenaline (NA) fluophore proximal to a crush, but did not produce an increase in the fluorescent intensity of, or the number of dense-cored vesicles (DCVs) within the neuronal perikarya. Calcium ions, but not magnesium ions, were able to block this effect of EGTA. Preparations incubated in the presence of colchicine (2.5 μg/ml) showed a reduction in the amount of fluorescent material accumulating proximal to a crash, but an increase in both the fluorescent intensity and the number of DCVs within the neuronal perikarya. The suggestion that calcium ions are required for the synthesis of some part of the NA-containing vesicle rather than for their loading onto the axoplasmic transport mechanism is discussed.
