    Antineutrophil Cytoplasmic Antibody in Patients with Primary Sjo¨gren’s Syndrome (1999)

    Notes: Abstract: The incidence, specificity and clinical significance of positivity for serum antineutrophil cytoplasmic antibody (ANCA) was investigated in 60 patients with primary Sjögren’s syndrome (SjS). The indirect immunofluorescence (IIF) technique and an enzyme-linked immunosorbent assay (ELISA) were used to measure ANCA. Purified myeloperoxidase (MPO), lactoferrin (LF), cathepsin-G (CTG) and elastase (HLE) served as ANCA antigens for the ELISA. Ten (16.7%) of the 60 SjS patients showed positivity by IIF for perinuclear, but not cytoplasmic, ANCA. Four of the 60 sera were shown to be positive for LF, four for MPO, 0 for CTG and 0 for HLE by ELISA. There was no correlation between ANCA positivity and clinical features. ANCA in patients with SjS might be an epiphenomenon of polyclonal B-cell activation.

    The effect of SiO2 addition in super-hydrophilic property of TiO2 photocatalyst (1999)

    Notes: Abstract The relation between the effect and the amount of SiO2 addition on photo-generated hydrophilicity of TiO2 thin film, was investigated by measuring the X-ray diffraction, the microstructure, the specific surface area and the TG-DTA. It was found that the optimum range existed in the amount of SiO2 addition to TiO2, 10–30 mol % SiO2 addition was most effective for contact angle of water. The SiO2 addition less than 30 mol % has a suppressive effect on the transformation of anatase to rutile and on the crystal growth of anatase in calcination, and it has large surface area. With the consequence that the photocatalytic activity of TiO2 and the capability of holding absorbed water which increases during UV irradiation improved.

    Stability and fragmentation of multiply ionized clusters (1998)

    Notes: Abstract: The stability of neutral, singly and multiply ionized silicon clusters, (N = 2-7, M = 0, , , ), has been investigated using an ab initio density functional method. We show that the fragmentation effect significantly affects the structure of mass-spectra of multiply ionized silicon clusters. For clusters, the clusters with a large fragmentation energy are found to correspond to the high peaks at N = 4 and 6 in mass-spectra. For clusters, a peak at N = 5 in mass-spectra has been predicted to be especially high.

    Notes: Abstract The electronic states of Fe atoms in Co[Fe(CN)5NH3 $$\cdot x $$ H2O were studied by means of 57Fe Mössbauer spectroscopy. The Mössbauer spectra of Co[Fe(CN)5NH3 $$\cdot $$ 6H2O show the coexistence of mixed valences for the Fe atoms and a magnetic relaxation at 4 K. When water molecules were removed, electron transfer from Co to Fe occurred.

    Study of optimum condition for synthesis of [γ-32P]ATP with high specific radioactivity (1999)

    Notes: Abstract The synthesis of [γ-32P]ATP with high specific radioactivity was investigated by the enzymatic method. We utilized a part of the glycolytic pathway which consists of three reaction steps. First, we examined the maximum radioactivity of H3 32PO4 without the decrease of labeling yield. Next, we examined the minimum amount of reagent without the decrease of labeling yield, because some reagents contain the phosphorus species as impurity. In this paper, we propose the optimum condition for synthesis of [γ-32P]ATP with high specific radioactivity. As our calculation, we will be able to obtain about 220 TBq/mmol specific radioactivity using 1.5 GBq of H3 32PO4.

    Notes: Abstract The solvent extraction behavior of [TcCl6]2− in the HCl-TBP system was studied together with that of its aqua complexes. It was deduced from the dependence of the distribution coefficient of [TcCl6]2− both on the HCl and TBP concentrations that a possible form extracted into TBP is H2[TcCl6](TBP)4. The distribution coefficients of aqua complexes of [TcCl6]2− were found to be in the order of [TcCl4(H2O)2]〈[TcCl6]2−〈[TcCl5(H2O)]−.
