    Notes: High-quality InGaN/GaN multiple-quantum wells (MQWs) with different In fractions varying from 0.04 to 0.30 have been grown on Ga-polarity GaN by N2 plasma-assisted molecular-beam epitaxy (rf-MBE). High-resolution x-ray diffraction results have indicated that the high interface quality and good reproducibility of the InGaN QW have been achieved. Photoluminescence spectra reveals the superior and intense luminescence properties of InGaN MQWs from ultraviolet (∼388 nm) to green-yellow (∼528 nm) range. We have shown that the Ga-polarity GaN underneath is the key parameter for the successful growth of InGaN MQWs by rf-MBE. © 2001 American Institute of Physics.

    Notes: GaN films with N- and Ga-polarity were grown on sapphire (0001) substrates using different buffer layers by plasma-assisted molecular-beam epitaxy. The surface stability of each lattice-polarity film during the growth interruption was studied by reflection high-energy electron diffraction (RHEED). It was found that the surface of N-polarity film was unstable against the exposure to the nitrogen plasma flux, while that of Ga-polarity one was stable. This provides a method to clarify the lattice polarity by the in situ RHEED observation directly. A model is proposed to explain the observed phenomenon, where the origin of the phenomenon is mainly attributed to the differences in surface dynamics processes and morphologies between the two kinds of lattice-polarity films. © 2000 American Institute of Physics.

    Notes: Time-resolved photoluminescence measurements at 5 K were performed to study the optical properties of InGaN/GaN multiple-quantum wells (MQWs) grown by plasma-assisted molecular-beam epitaxy (rf-MBE). Stimulated-emission (SE) phenomena by optical pumping were observed under the high-excitation density from the InGaN/GaN MQW samples with the In composition varying from 0.04 to 0.16. It was found that the threshold density for SE phenomena strongly depended on the In composition, where the lowest threshold density was 69 μJ/cm2 from our samples. Our results show a potential of rf-MBE technique for the future optical device applications. © 2001 American Institute of Physics.

    Notes: Background A recent report provided evidence that a disintegrin and metalloprotease domain 33 (ADAM33), a member of the ADAM family, is a novel susceptibility gene in asthma linked to bronchial hyper-responsiveness. However, there has been no investigation of the genetic role of ADAM33 variants in nasal allergy.Objective The purpose of this study was to test the association between ADAM33 polymorphisms and Japanese cedar pollinosis (JCPsis), a most common seasonal allergic rhinitis in Japan.Methods We conducted a case–control association study among a Japanese population, involving 95 adult individuals with JCPsis and 95 normal healthy controls. A total of 22 single-nucleotide polymorphisms (SNPs) in ADAM33 were genotyped using PCR-based molecular methods.Results Six SNPs of ADAM33 gene, three in introns (7575G/A, 9073G/A and 12540C/T) and three in the coding region (10918G/C, 12433T/C and 12462C/T), were strongly associated with JCPsis (P=0.0002−0.022 for absolute allele frequencies) and most of the SNPs were in linkage disequilibrium with each other. A higher frequency of the common alleles of these SNPs was noted for the subjects with JCPsis in comparison with healthy controls. We also identified a haplotype associated with the disease susceptibility. In addition, associations were found between ADAM33 polymorphisms and various cedar pollinosis phenotypes including clinical severity, eosinophil counts in nasal secretion and allergen-specific IgE levels in sera, but not total serum IgE levels.Conclusion These results indicate that polymorphisms in the ADAM33 gene are associated with susceptibility to allergic rhinitis due to Japanese cedar pollen, but the functional relationship still needs clarification.

    Notes: Two patients became infested with Gnathostoma nipponicum after eating raw loach-fish they had caught in a rice field in central Japan. A fragment of Gnathostoma was found in a biopsy from one of them. The sera of both patients reacted with Gnathostoma antigen using indirect immunofluorescence. Scanning electron microscopy was performed on blocks of the paraffin-embedded parasite sample and the viscera of a fish from the same rice field. The risk of eating raw freshwater fish is discussed.

    Notes: In Sakhalin taimen Hucho perryi two choriogenins have been identified in serum, designated high- and low-molecular-weight vitelline envelope-related protein (hVERP and lVERP). Two immunoassays were developed using specific antibodies; single radial immunodiffusion (SRID) and enzyme-linked immunosorbent assay (ELISA), for measurement of the precursors to vitelline envelope proteins. ELISA measures hVERP and lVERP in serum at concentrations as low as 16 and 47 ng ml−1, respectively. Using these immunoassays, changes in serum levels of VERP were measured after treatment with E2 and during oocyte growth. When immature 2-year-old taimen were injected with 2 mg E2 per kg body weight, both VERPs were induced in serum within 24 h. In the course of the first ovulation, serum VERPs levels increased in September (8 months before ovulation), reached maximum in January, and decreased sharply prior to ovulation in May. These changes generally paralleled that of vitellogenin except for the drastic decrease of VERPs in May.

    Emulsifying and Surface Properties of Wheat Gluten under Acidic Conditions (2001)

    Notes: The solubility of wheat gluten was greatly improved at pH 4 or lower where it showed good emulsifying activity. This might be due to its high surface activity in the acidic pH range and the formation of a stable protein film surrounding the oil droplets. Among the major gluten proteins, gliadins showed higher surface activity than glutenins. The content of glutenins in the adsorbed protein film was higher than that of gliadins, and glutenins are likely to have been adsorbed more tightly than gliadins. These results suggest that gluten proteins exhibit complex behavior, such as adsorption/desorption/displacement/rearrangement during the adsorption process in a gluten-stabilized emulsion.

    Notes: Escherichia coli in phosphate-buffered saline irradiated with far-infrared (FIR) energy was injured and killed even under the condition where the bulk temperature of the suspension was maintained below the lethal temperature. Using four kinds of antibiotics (penicillin G, chloramphenicol, nalidixic acid and rifampicin), we investigated the FIR irradiation-induced damage to E. coli on the basis of the sensitivity changes to the antibiotics. FIR irradiation increased the organism’s sensitivity to rifampicin both below and above the lethal temperature. The increase in sensitivity to chloramphenicol was observed only when FIR irradiation occurred above the lethal temperature. These results suggest that the mechanism of FIR irradiation-induced death in E. coli differs according to whether the radiation exposure occurs above or below the lethal temperature.

    Description / Table of Contents: Zusammenfassung Neue chemische und optische Daten für antimon- und bismuthführende Hemusite auf epithermalen Au-Ag-Cu Lagerstätten in Japan werden vorgelegt. Die empirische Formel für die antimon-führende Varietät aus der Iriki-Mine ist: (Cu5.83Fe0.14Ag0.01)Σ5.98Mo1.03(Sn0.54Sb0.41Te0.03Bi0.02)Σ1.00 (S7.85Se0.15)Σ8.00, und die der Sb-Bi Varietät aus der Kawazu Mine ist: (Cu5.84Fe0.14Ag0.01)Σ5.99M01.03(Sn0.82Sb0.11Bi0.l0Te0.04)Σ1.07 (S7.80Se0.12)Σ7.92. Die theoretische Formel von Hemusit ist Cu+ 4Cu2+ 2Mo4+Sn4+S8, während die wahrscheinlichere Formel für den Hemusit von Iriki Cu+ 4Cu2+ 1.5Mo4+Sn4+ 0.5Sb5+ 0.5S8, mit Sb5+ an der Stelle von Sn4+, das(SbS4)3− Tetraeder bildet, wie zu erwarten ist, unter der Voraussetzung, da♭ das Metall zu Schwefelverhältnis 1 und die Struktur sphaleritähnlich ist. Bi3+ kann jedoch nicht in dieser Weise untergebracht werden, und das führt zu einem Mangel an (S + Se) für den Hemusit von Kawazu. Die Reflektions-Spektren beider Minerale werden mit denen des Wolfram-Equivalents von Hemusit (Kiddcreekit) verglichen. Die Beziehung zwischen Hemusitsensu stricto und diesen jetzt beschriebenen Varietäten wird auf der Basis einfacher und gekoppelter chemischer Substitution diskutiert. Auf dieser Basis werden Schlüsse auf die Valenz von Sb, Bi Mo und Cu in der Hemusit-Struktur gezogen.
    Notes: Summary New compositional and optical data are reported for antimonian and antimonianbismuthian varieties of hemusite from epithermal Au-Ag-Cu deposits in Japan. The empirical formula for the antimonian variety, from the Iriki mine is: (Cu5.83Fe0.14Ag0.01)Σ5.98Mo1.03(Sn0.54Sb0.41Te0.03Bi0.02)Σ1.00(S7.85Se0.15)Σ8.00, and that of the Sb-Bi variety from the Kawazu mine is: (Cu5.84Fe0.14Ag0.01)Σ5.99Mo1.03(Sn0.82Sb0.11Bi0.l0Te0.04)Σ1.07(S7.80Se0.12)Σ7.92. The theoretical formula of hemusite is Cu+ 4Cu2+ 2MO4+Sn4+S8, whilst the most probable formula of the Iriki hemusite is Cu+ 4.5CU2+ 1.5Mo4+Sn4+ 0.5Sb5+ 0.5S8, with Sb5+ substituting for Sn4+ and forming (SbS4)3− tetrahedra as might be expected, given that the metal to sulphur ratio is 1, and given the sphalerite-like structure of the mineral. However Bi3+ cannot be so accommodated, resulting in a deficiency in (S + Se) for Kawazu hemusite. Reflectance spectra for both are compared with those of the tungsten analogue (compositional) of hemusite, kiddcreekite. The relationship between hemusitesensu stricto and these newly reported varieties is discussed in terms of simple and coupled chemical substitutions, and inferences are drawn on the valency of Sb, Bi, Mo and Cu in the hemusite structure.
