    Notes: Nanometer-scale mounds were fabricated by applying voltage pulses between a substrate and an atomic force microscope cantilever coated with magnetic material. Mounds were formed on both insulator and conducting substrates. Magnetic force microscopy (MFM) observations of the fabricated mounds were performed, and the contrast was turned over by reversing the magnetization of the tip, which is convincing proof that the mounds are magnetic. The MFM images also suggest that the mounds are perpendicularly magnetized. These results demonstrate that scanning probe microscope based nanofabrication is a promising method to fabricate nanoscale magnetic dots on any kind of substrates. © 1996 American Institute of Physics.

    Spin-polarized secondary electron microscopy of soft magnetic films on antiferromagnetic substrates : The 41st annual conference on magnetism and magnetic materials (1997)

    Notes: Coupling of soft magnetic films to antiferromagnetic substrates was studied by spin-polarized secondary electron microscopy. Permalloy (Ni80Fe20 alloy) films were deposited on antiferromagnetic NiO(111) single-crystal substrates. A domain structure consisting of fine grains (∼50 μm) was characteristic of the NiFe film deposited without applying magnetic field. The domain image and its response to applied field suggested existance of local easy axis and local unidirectional anisotropy. When macroscopic unidirectional anisotropy was introduced to the NiFe film by depositing under an applied dc magnetic field, many of the fine grains disappeared and the film showed large domains (∼1 mm). In the large domains, small elongated reversed domains (∼20 μm×60 μm) aligned parallel to each other implying local easy axis of magnetization. The type of domain behavior described above was not observed in a NiFe film on MgO(111) substrate that had the same crystal structure as NiO but no magnetic ordering. An x-ray analysis revealed that the local easy axes observed in NiFe/NiO specimens coincided with the [112¯] of the NiO crystal lying in the (111) substrate plane, which supported coupling of the NiFe film with the single-crystal substrate. © 1997 American Institute of Physics.

    Notes: Abstract We investigated metabolic changes in brain tumours following treatment, using proton magnetic resonance spectroscopy. In meningiomas, effective therapeutic embolisation led to an acute increase in lactate. In radiosensitive tumours such as malignant lymphoma, a decrease in lactate and in increase inN-acetyl-aspartate occurred after radiotherapy, which preceded changes observed on magnetic resonance imaging. On the other hand, no significant changes in spectral patterns were observed in malignant gliomas resistant to therapy. Tissue characterisation of brain tumours by spectral patterns on proton magnetic resonance spectroscopy remains controversial. However, we have shown it to be sensitive to metabolic changes following treatment, which may reflect the efficacy of the therapy.

    Metabolic and neurological patterns in chronic cerebral infarction: a single-voxel 1H-MR spectroscopy study (1997)

    Notes: Abstract The details of brain metabolism in chronic cerebral infarcts have not been clarified. Using proton MR spectroscopy (1H-MRS) at 1.5 T, we measured biochemical changes in 16 patients with large infarcts involving the motor cortex in the chronic phase (median 293.9 days) and related the findings to clinical data. Localised spectra were obtained using point-resolved spectroscopy, with an echo time of 270 ms. Regions of interest were placed on the frontal lobe, including the precentral gyrus and central sulcus. Motor function was assessed by the manual muscle power test at the time of the 1H-MRS study. Only three patients with severe paresis had no signal in the lesions and a lactate signal was obtained in 13 cases. N -acetyl aspartate (NAA) was observed in 4 cases with recanalisation of an occluded vessel. Motor function correlated strongly with the NAA/choline-containing compounds (Cho) ratio (P 〈 0.01) and lactate/Cho ratio (P 〈 0.01). We found various metabolic patterns, reflecting residual neurological function.

    Notes: Abstract. Supravalvular aortic stenosis (SVAS) is rare in twins. We report monozygotic twins, both of whom had SVAS, coronary ostial stenosis, and peripheral pulmonary arterial stenosis, but no other phenotypic features of Williams syndrome. One of the twins died suddenly, but the SVAS and the right and left coronary ostial stenoses were enlarged successfully at operation in the other twin.

    General theory of coincidence-site lattices, reduced 0-lattices and complete pattern-shift lattices in arbitrary crystals (1976)
    [S.l.] : International Union of Crystallography (IUCr)

    Notes: The definition of a lattice and its superlattice is given algebraically. A coincidence site lattice (CSL) is defined as an intersection lattice of any two crystal lattices, and a complete pattern-shift lattice (DSCL) as the set theoretically smallest lattice containing both crystal lattices as superlattices. In the case where the two lattices are related by a non-singular matrix (having non-zero determinant), the so-called 0-lattice may be generated from the two crystal lattices. Any translation of the 0-lattice by all the vectors of one of the crystal lattices forms a lattice, i.e. a reduced 0-lattice. As a result of the theory of groups and numbers, the reduced 0-lattice (abbreviated to ROL) is homomorphic to the DSCL. It is shown that the factor group of all cosets of lattice 1 in the DSCL (in the ROL) is isomorphic with the factor group of all cosets of the CSL in lattice 2 (in the 0-lattice). The volume of a unit cell is derived for all the lattices generated by the two crystal lattices. Secondly, the reciprocal of a lattice is introduced and the reciprocity between the CSL and the DSCL determined by the reciprocals of the two crystal lattices is shown as a special case of a theorem mentioned about modules over a ring. Finally a complete diagram of relationships between b-lattices and 0-lattices for direct lattices and reciprocal lattices is given.

    Notes: In cubic polycrystals, combinations of coincidence orientation relationships at a triple junction of grains A, B and C can be obtained by using the equation ΣCA = ΣABΣBC/d2, where d is a common divisor of ΣAB and ΣBC. This paper describes the derivation of this equation and shows several models of polycrystals composed of specially selected coincidence boundaries using the above equation.

    Cathepsin B in gingival crevicular fluid of adult periodontitis patients: Identification by immunological and enzymological methods (1996)

    Notes: Abstract Cathepsin B (EC 3.4.22.1), a typical lysosomal cysteine proteinase was identified immunologically with anti-human cathepsin B antibody in inflammatory exudate, gingival crevicular fluid (GCF) of adult periodontitis patients. The sensitive enzyme immunoassay (EIA) system initially developed, was rarely influenced by the presence of endogenous, cysteine proteinase inhibitors, cystatin(s), indicating that it is possible to quantify the gross amount of cathepsin B including free enzyme forms and enzyme-inhibitor complex forms using this EIA system. The cathepsin B levels in, GCF as determined by EIA and the activity measured with Z-Arg-Arg-MCA showed positive and significant correlation with various clinical parameters. Immunoblotting analysis revealed that the molecular form was a 29 kDa mature enzyme. More than 95% of Z-Arg-Arg-MCA hydrolytic activity in each GCF sample was inhibited by CA-074, specific inhibitor of cathepsin B. These results strongly suggested that the gross amount of cathepsin B in GCF as well as its activity level is closely associated with the severity of the disease and that cathepsins B play an important role in the pathogenesis of periodontitis.
