    Notes: Summary Dose-dependent relaxations were induced by dopamine in human pulmonary arteries that had been contracted with prostaglandin F2α without α-adrenergic blocking agents. The dopamine-induced relaxation was inhibited by haloperidol and fluphenazine, but not by domperidone, suggesting that this relaxation was mediated via DA1 receptors.

    Notes: Abstract Auditory brainstem response (ABR) was used to assess possible brainstem damage in 76 neonates with asphyxia and intracranial haemorrhage (ICH). Fifty-eight neonates had ICH, 52 had neonatal asphyxia and 34 of these patients had both. Eighty-nine percent of the patients with neonatal asphyxia showed some abnormal patterns in response, the major one being an increase in the threshold of wave V. In the ICH group, abnormal patterns were observed in 62.5%, among whom the prolongation of the I–V interpeak latency (IPL) and of wave V latency was seen more frequently than the increase of threshold of wave V. In the case of neonatal asphyxia associated with ICH, both the prolongation of the latency and the increase of threshold were observed equally. These abnormalities of ABR were associated with worsening clinical condition and conversely normalized gradually following the improvement of the underlying disease. Especially the I–V IPL, wave V latency and the threshold of wave V could serve as indicators of the treatment.

    Notes: Thin films of III-V nitride semiconductors (AlN, GaN, InN), mixed-crystalline films (AlxIn1−xN), and multilayered films (GaN/InN)n were grown by rf magnetron sputtering at low substrate temperatures below 500 °C. These films were characterized by x-ray diffraction, Raman scattering, optical absorption, and electrical measurements; it was proved that they have high crystal quality comparable to the previously reported data obtained by other growth methods. Dependence of the band-gap energy of AlxIn1−xN on composition x was determined. Multilayered films of (GaN/InN) were prepared for the first time; these films showed the characteristic diffusion property to make an ordered-alloy superlattice.

    Notes: Epitaxial thin films of LiNbO3 and LiTaO3 were grown on sapphire substrates by the rf-magnetron sputtering method. Structural characterization was made by several spectroscopic measurements: x-ray diffraction, Raman scattering, and optical absorption. We obtained epitaxial thin films with lattice-mismatched strained layers, without misfit defects which are usually created at the interface. Impurity-ion (Nd3+ and Cr3+) doped films were also grown; these films had larger refractive indices than the pure films. Furthermore, the heteroepitaxial thin films of up to 10 alternating LiNbO3/LiTaO3 layers were successfully grown, and their periodic structures were studied by optical second-harmonic generation.

    Notes: Abstract Electrical and dielectrical properties of poly(bis(β-phenoxyethoxy)phosphazene) (I) and its complexes with various content ratios of AgSO3CF3 to monomeric unit (0.25/1 (II) and 0.5/1 (III) in molar ratio) were investigated.Dc conductivity of respective samples at 18 °C were 6.1×10−12, 4.4×10−9, and 7.1×10−8 S/m.Dc conduction was considered to be due to ion hopping. Charge mobility ranged from 3×10−12 to 6× 10−11 m2/Vs depending on the applied field in sample II. In sample I, a tanδ peak was found which can be ascribed to molecular relaxation of main chains. The peak vanished upon introducing AgSO3 CF3. Temperature dependence of total conductivity (σ T ) measured byac method in the temperature range between −150 °C and 50 °C showed several peaks at the temperatures corresponding to the peak temperatures of tanδ. Total conductivities of respective samples at 100 kHz were 4.9×10−7 (69 °C), 1.7×10−4 (45 °C), and 1.5×10−4(40°C)S/m.

    Notes: Abstract A non-destructive method for determining the amount of actinoids has been developed. The method is based on thermal neutron coincidence counting and employs a selective detection of neutrons resulting from the spontaneous fission of actinoids. The detection system is described in detail and the measurement results of244Cm as an example are presented. The results show that the measured fission rate of244Cm is consistent with the fission rate calculated from ENDF/B-V data and that the amount of244Cm can be determined within about 5% accuracy even in the presence of a large amount of actinoids, for example, up to 2.6·106, 3.6·104, or 1.6·103 times in the mass ratio of239Pu,241Am, or240Pu to244Cm, respectively.

    Notes: Abstract Thalictrum minus cells immobilized in calcium-alginate beads were cultured in a newly devised bioreactor for the purpose of producing berberine. This system could prevent cells from leaking out of the beads, allowing them to release most of the berberine synthesized into the liquid medium. Furthermore, the biosynthetic capability of the immobilized cells was found to be comparable to that of freely suspended cells.

    Notes: Abstract A new bioreactor (liquid-gas two-phase system) was devised for berberine-secreting Thalictrum minus cells immobilized in calcium alginate beads, which were alternately soaked in medium, and exposed to air. The highest yield of berberine (875 mg/l) was obtained by setting the cycle of medium supply and air supply for 30 seconds and 2 minutes, respectively, during a culture period of 30 days. Under such conditions of batch culture, the berberine productivity of immobilized cells was as high as that of freely suspended cells. Furthermore, the rate of berberine production by immobilized cells remained constant at a high value (50 mg/l/day) for a period of 60 days of semi-continuous culture achieved by renewal of medium at intervals of 10 days.
