    Notes: By collision with hyperthermal atoms, desorption of surface species can be induced. It is called collision induced desorption (CID). We studied a CID process of N2 adsorbed on a Ni(100) surface in an apparatus equipped with a molecular beam apparatus and an Fourier transform infrared spectrometer. The CID cross section was estimated, and the mechanism was discussed. © 1999 American Institute of Physics.

    Measurement of the Hg distribution in a high-pressure arc lamp by x-ray absorption (1998)
    [S.l.] : American Institute of Physics (AIP)

    Notes: We have used an x-ray absorption technique to measure the distribution of Hg atoms in a pure-Hg high-pressure arc lamp. The x rays are obtained from a molybdenum-anode x-ray tube at an accelerating potential of 25.3 kV. The spectral distribution of x rays which produce the absorption signal consists mainly of the Mo Kα and Kβ fluorescence peaks at 17.5 and 19.6 keV, respectively. Plane-wave illumination of the lamp and two-dimensional detection of the transmitted x rays allow us to probe the Hg atom density in all regions of the lamp, simultaneously, with a spatial resolution of 170 μm. A complete two-dimensional map of the density is obtained by Abel inversion of the absorption data. This map extends all the way out to the arc-envelope boundary and includes the cold regions of the discharge behind the electrodes. A temperature map of the discharge is obtained by combining the density information with an optical emission measurement of the core temperature at a single axial location. © 1998 American Institute of Physics.

    Improved dc characteristics of AlGaN/GaN high-electron-mobility transistors on AlN/sapphire templates (2002)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 81 (2002), S. 1131-1133

    Notes: High-electron-mobility transistors (HEMTs) have been demonstrated on both AlN/sapphire templates and sapphire substrates, and the dc characteristics of the fabricated devices were examined at room temperature. Better dc characteristics with high extrinsic transconductances and drain current densities were observed in the HEMTs grown on AlN/sapphire templates when compared with the HEMTs on sapphire substrates. Extrinsic transconductances of 214 and 137 mS/mm for Wg/Lg=15/2 μm HEMTs on AlN/sapphire templates and HEMTs on sapphire substrates were achieved, respectively. The enhancement of dc characteristics with small variations in threshold voltage (≤130 mV) is due to the reduction of dislocation density (1.5×108 cm−2). The decrease of dark spot density has been confirmed in the GaN grown on AlN/sapphire templates using cathodoluminescence measurements. The advantage of using AlN/sapphire templates is that low dislocation density GaN layers at a high temperature can be grown without using low-temperature-grown GaN buffer layers. © 2002 American Institute of Physics.

    Immunostimulant effects of nucleotide isolated from yeast RNA on carp, Cyprinus carpio L. (2001)

    Notes: Nucleotides from yeast RNA were evaluated for their ability to enhance the non-specific immune responses in carp, Cyprinus carpio. Oral administration of nucleotides to fish daily for 3 days resulted in enhanced responses of phagocytic and nitroblue tetrazolium (NBT) activities in kidney phagocytic cells. This activation of kidney cells was observed for at least 10 days post-treatment. The serum complement and lysozyme activities also increased in fish treated with nucleotides. Furthermore, the number of Aeromonas hydrophila in nucleotide-treated fish significantly decreased in the blood, kidney and liver after intraperitoneal injection. Thus yeast nucleotides appear to enhance non-specific immune responses in fish.

    Expression of endothelial nitric oxide synthase in human eccrine clear cells (1997)

    Notes: Nitric oxide is generated from L-arginine by nitric oxide synthase (NOS), which has at least three isoJorms: endothelial-type NOS (eNOS) and brain-type NOS (bNOS) are constitutive enzymes, and inducible-type NOS (iNOS) is expressed after stimulation. Studies by the avidin-biotin immunocomplex method, revealed eNOS immunoreactivity exclusively in the human eccrine clear cells. No eNOS immunoreactivity was observed in the eccrine dark cells or myoepithelial cells. No staining of iNOS or bNOS was observed in the eccrine yland. These findings indicate that NO pUiys a physiological part in the production and/or excretion of sweat in the human skin eccritie gland.

    Detection of koi herpesvirus in common carp, Cyprinus carpio L., by loop-mediated isothermal amplification (2004)

    Notes: Loop-mediated isothermal amplification (LAMP) is a novel method that amplifies DNA with high specificity and rapidity under isothermal conditions. In this study, using the LAMP method, a protocol for koi herpes virus (KHV) detection in common carp was designed. A set of four primers, two inner and two outer, were designed based on the sequence of the thymidine kinase (tk) gene of KHV. Time and temperature conditions for detection of KHV were optimized for 60 min at 65 °C. The detection limit using LAMP was found to be similar to that by polymerase chain reaction. In this study, we have developed a highly sensitive and rapid diagnostic procedure for detection of KHV infection in common carp.

    Notes: A comparative study between EHVF (eel herpesvirus in Formosa) and HVA (Herpesvirus anguillae) was performed. Similar syncytia were produced by each virus in cell lines infected with the viruses and similar viral yields were obtained. Significant cross-reactivity was observed in neutralization tests between HVA and EHVF but HVA and EFVF were distinctly different from channel catfish virus (CCV). An electrophoretic analysis of the structural proteins of EHVF and HVA produced similar electrophoretic patterns. Western blotting analysis of the viral proteins, using antiserum against EHVF, supported the results obtained in the cross-neutralization test. In conclusion, the isolates of HVA and EHVF are tightly clustered.

    Diversification in MHC class II invariant chain-like proteins among fishes (2004)

    Notes: The major histocompatibility complex (MHC) class II invariant chains are important for an efficient and complete presentation of antigens by MHC class II molecules. Invariant chain-like proteins (Iclp) 1 and 2 were identified by expressed sequence tag analysis from cDNA library of common carp head kidney (HK) stimulated with concanavalin A and lipopolysaccharide. The sequences were 1043 and 1016 bp in length encoding 234 and 198 amino acid proteins, respectively. Based on their predicted structure, the genes harboured transmembrane domain (TMD) and Tg (thyroglobulin) type 1 domains. Expression analysis revealed that both genes were expressed in normal tissues of HK, intestine, brain and gill. By database search, similar homologues were found in Atlantic salmon, fugu and catfish. Phylogenetic and alignment analysis indicate diversity among fish Iclps.
