    STUDIES ON SOLUBLE PROTEINS RELEASED FROM THE SYNAPTIC VESICLES OF RAT BRAIN CORTEX (1971)

    Notizen: Abstract— The soluble proteins released from the synaptic vesicles of rat cerebral cortex were studied. One fraction (D4) of these proteins was released in parallel with release of acetylcholine when synaptic vesicles were incubated at 37°C for 10 min in isotonic medium. Another fraction (Dj) was liberated from synaptic vesicles when their membranes were ruptured by mild treatment under hyposmotic conditions and freeze-thawing after release of D1 fraction. Fractions D1 and D2 contained 12 and 9 per cent, respectively, of the total protein in the synaptic vesicles. Some properties of these fractions were investigated by zone electrophoresis and ultracentrifugation, and by measuring their binding capacities for [14C]acetylcholine and various enzyme activities related to acetylcholine metabolism.

    Time-of-flight neutron small-angle scattering from a superconducting composite wire (1982)

    Notizen: The precipitation behavior in the Ti–27at.%Nb–6at.%Ta–6at.%Zr alloy aged at 643 K was examined by means of time-of-flight neutron small-angle scattering. When the alloy was aged, fine-scale α precipitates appeared. During the precipitation process, each precipitate grew in size, but the total number of precipitates remained nearly constant up to 1 Ms of ageing. The increase of critical superconducting current density could be connected with increasing size of α precipitates. The specimen for the measurements consisted of a composite containing 3721 filaments in a copper matrix. The use of neutrons was shown to give great advantages for the investigation of precipitation phenomena.

    Untersuchungen zur Wirkung von Elektrizität auf den Myoglobingehalt humaner Herz- und Skelettmuskulatur (1984)

    Beschreibung / Inhaltsverzeichnis: Zusammenfassung Myocard von 8 Todesfällen durch Elektrizität wurde mittels der indirekten Immunoperoxidase-Methode auf seinen Myoglobingehalt untersucht. In 7 Fällen wurden deutliche Myoglobinaustritte aus den Muskelfasern nachgewiesen. Nach postmortaler Einwirkung von Elektrizität auf Myocard und Skelettmuskulatur von 9 Fällen mit natürlicher Todesursache wurden mit gleicher Untersuchungstechnik ebenfalls starke Myoglobinverluste demonstriert. Die Befunde werden in erster Linie auf Ischämien bzw. thermische Effekte, die durch die elektrische Energie verursacht wurden, zurückgeführt. Da die Myoglobindarstellung eine wesentlich bessere Beurteilung geschädigter Herzmuskelabschnitte zuläßt als die HE-Färbung, kann sie bei der forensischen Untersuchung des Todes durch Elektrizität von Vorteil sein.
    Notizen: Summary The myoglobin content of heart muscles was examined by the indirect immunoperoxidase method in eight autopsy cases where death was due to electricity. Seven cases showed a considerable release of myoglobin from the myocardial fibers. In experimental comparison, the heart muscles and skeletal muscles from nine cases where death was natural were exposed to electricity, and considerable deletion of myoglobin was also demonstrated. We believe that the findings of ischemia or thermal effects due to electricity were the cause of the release of myoglobin. Because the demonstration of myoglobin is preferable to estimation of the damaged areas of muscles by hematoxylin-eosin staining, this examination may be more advantageous in forensic examination of death by electricity.

    The age-dependent difference in the response of the vagina to the neonatal administration of testosterone propionate in Long-Evans female rats (1981)

    Notizen: Summary The ability of the vaginal epithelium to respond to testosterone propionate by producing keratin was established when female rats were 3 days of age, whereas the vaginal stroma from rats 2 days old or less was capable of responding to the androgen and might destroy the vaginal epithelium.

    In vivo synthesis of glycogen by phosphorylase system (1980)

    Notizen: Summary Application of conventional histochemical techniques to the living chick retina demonstrates that phosphorylase can synthesize glycogen (polyglucose) in vivo, in the paraboloid of the accessory cone. Natural in vivo glycogen synthesis may therefore be due to glycogen synthetase and phosphorylase systems, although phosphorylase is normally regarded as a glycolytic enzyme.

    Notizen: Abstract A fourteen month-old boy with atypical phenylketonuria was treated with 5-hydroxytryptophan, L-dopa and peripheral aromatic amino acid decarboxylase inhibitor (Ro 4-4602:benserazide). Despite the good control of plasma phenylalanine on a low phenylalanine diet, he had shown no improvement in his development but progressive neurological symptoms, such asiirritability, convulsions and decrease voluntary movement. After beginning neurotransmitter therapy, his irritability disappeared promptly and the other symptoms diminished. He gradually reached his developmental milestones. At two and a half years of age, he had recovered sufficiently to be able to walk freely on treatment with 13 mg/kg/day of 5-hydroxytryptophan, 11 mg/kg/day of L-dopa and 2.7 mg/kg/day of benserazide in combination with slight restriction of phenylalanine intake (100 mg/kg/day). Levels of serotonin and 5-hydroxyindoleacetic acid were low in the patient's CSF. His urinary biopterin (Crithidia factor) excretion was low. An increase in serum biopterin following L-phenylalanine loading was not found. Dihydropteridine reductase activity in his skin fibroblasts was normal. He excreated large amounts of erythro- and threo-neopterins (but only a trace of biopterin) in his urine. After loading with phenylalanine the urinary excretion of neopterins was even more enhanced, but biopterin remained at low levels. These findings indicated that the patient has a dihydrobiopterin synthetase deficiency.

    Notizen: Abstract The spin polarized electronic structure around a positive muonμ + at the tetrahedral interstitial site of silicon is calculated by use of the LCAO-Green's function method and the local spin density functional formalism. The bonding hyper deep impurity state below the valence band and the antibonding deep one in the gap caused by the strong sp hybridization in the majority spin band give the most large contribution to the hyperfine coupling constant ofμ +. The reduction of the hyperfine coupling constant,A, experienced byμ + at absolute zero is calculated to be 0.406 in satisfactory agreement with the experimental value of 0.405 ± 0.026 or 0.450 ± 0.020.
