    Notes: Abstract A girl with type 1a pseudohypoparathyroidism (PHP) presented several hormonal abnormalities. Although she had eluded neonatal thyroid screening, she was diagnosed as having hypothyroidism at the age of 5 months. Thereafter, a diagnosis of PHP was made on the basis of skeletal features of Albright osteodystrophy and lack of both cyclic adenosine monophosphate (c-AMP) and phosphaturic responses after parathyroid hormone (PTH) infusion. The basal levels of luteinizing hormone (LH) and follicle stimulating hormone (FSH) were higher than normal and showed exaggerated responses to luteinizing hormone-releasing hormone (LH-RH). There was no growth hormone (GH) response to arginine infusion, and the prolactin (PRL) response after thyrotropin-releasing hormone (TRH) infusion was also impaired. The stimulating guanine nucleotide-binding protein (Ns) activity of the erythrocytes was reduced to 66.9%. The skeletal age was not delayed at the age of 5 months in spite of the hypothyroid state, and it advanced following thyroxine and vitamin D treatments.

    Ontogeny of cholecystokinin-8 and glutamic acid decarboxylase in cerebral neocortex of macaque monkey (1989)

    Notes: Summary Concentration of cholecystokinin-8 and the activity of glutamic acid decarboxylase were determined in the various cerebral cortical subdivisions of Japanese monkey (Macaca fuscata fuscata) at three different ages (embryonic 4 months, full-term and adult). The CCK-8 immunoreactive material extracted with 90% methanol from the cerebral cortex of the adult and foetal monkey were shown to be identical with synthetic cholecystokinin-8 by the criterion of co-elution on gel filtration chromatography (Sephadex G-50). The peptide concentration increased dramatically by about 30–80 fold (in terms of protein) and 17–28 fold (in terms of wet weight) between embryonic 4-month-old and full-term monkeys, while the level decreased 1/6–1/16 (protein) and 1/4–1/10 (wet weight) between full-term and adult monkeys. In adults, the highest levels of the peptide was observed in the association cortex, orbital prefrontal cortex and posterior parietal cortex. Glutamic acid decarboxylase activity, on the other hand, gradually increased about 4–10 fold (protein) between embryonic 4-month-old and adult animals and there was little variation in the increase rate among the cerebral subdivisions. In contrast to cholecystokinin-8, no reduction in the enzyme activity occurred between full-term and adult animals. The high level of cholecystokinin-8 in the embryonic period suggests that the peptide may participate in the regulation of the development of primate cerebral cortex.

    Characteristics of βA chromosome haplotypes in Japanese (1987)

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract DNA polymorphism patterns linked to the βA-globin gene were analyzed in healthy Japanese using four different restriction endonucleases. The chromosomes with the βA-globin gene were mapped through an evaluation of the presence of seven different restriction sites (HincII 5′ to ε; HindIII in Gγ and Aγ; HincII in, and 3′ to, ψβ1; AvaII in β; Bam-HI 3′ to β). Among 36 chromosomes analyzed, 20 chromosomes had a haplotype of [+−−−−−+]. Among 55 individuals examined, 7 possessed a homozygous haplotye of [+−−−−−+]. All Japanese with the AγT-globin gene had a subhaplotype of [−++−+] 5′ to the δ-globin gene. Their major haplotypes were [−++−+−+] and [−++−++−]. It was expected that the presence of the AγT-globin gene in Japanese may be deduced from subhaplotypes 5′ to the δ-globin gene.

    Description / Table of Contents: Sommaire Pour simuler l'auto-régulation du volume de fluide du corps humain au moyen de la tonicité, des modèles sont mis au point de différentes manières et l'on prouve que tous permettent de reproduire la réponse type d'organismes quelconques à l'ingestion d'eau. La variété des modèles est dûe à des incertitudes sur la physiologie des reins et des hormones que ces modèles utilisent comme principe de départ.
    Abstract: Zusammenfassung Kontroll-Modelle des Körperflüssigkeitsvolumens durch Tonus sind auf verschiedene Weisen entwickelt worden, und alle zeigen, daß es möglich ist, die charakteristische Antwort des Organismus auf Aufnahme von Wasser zu reproduzieren. Die Verschiedenheit der Modelle ist auf Unsicherheiten der zugrundeliegenden Nieren-und Hormonphysiologie zurückzuführen.
    Notes: Abstract Control models of body fluid volume via tonicity are developed in several ways, and all are demonstrated to be able to reproduce the characteristic response of organisms to ingestion of water. The diversity of models is due to uncertainties in renal and hormonal physiology, on which they are based.

    Some propositions on caustics and an application to the biaxial-fracture problem (1985)

    Notes: Abstract Some fundamental problems on the optical method of caustics, which is used to determine the value of the stress-intensity factor, are studied. The paper shows that the radiusr o of the initial curve considerably affects the results and describes a method to eliminate this effect. This method is also applied to the biaxial-stress fracture problem. It is shown that the biaxial stress affects the fracture toughness of thin specimens of Plexiglas sheets and that the fatigue-crack-growth rate is increased due to the compressive stress along the crack line.

    Immobilization of cellulolytic and hemicellulolytic enzymes on inorganic supports (1987)

    Notes: Commercial cellulase preparations from Trichoderma viride and Aspergillus niger were immobilized on porous silica glass and ceramics such as alumina and titania with titanium tetrachloride (TiCl4) and on their silanized derivatives with glutaraldehyde (GLUT). The amounts of the immobilized enzymes were in the range 10-50 mg/g carrier (dry) depending on the kind of carrier and immobilization method. Their activities toward carboxymethyl cellulose (CMC), xylan, aryl-β-glucoside, and aryl-β-xyloside were 3-53% of those of the native enzymes. The optimum pH of the enzymes shifted to the acidic side in most cases, whereas the optimum temperatures were nearly the same as those of native ones. The activity of immobilized enzyme preparations towards CMC did not change significantly during continuous operation over a periods of 60 days. Finally, xylan was hydrolyzed with the immobilized enzymes, and the sugars formed were investigated.

    Isoscalar magnetic moments and the role of the δ-hole excitation (1985)

    Notes: Abstract Expectation values of the total spinS of nucleons in nuclei are very quenched. This quenching is shown to be hardly explained by the mixture ofΔ-hole states. The quenching thus provides the best evidence for the role of non-central parts of the nucleon-nucleon interaction, especially the tensor interaction.
