    Notes: The expression for the analytical derivatives of the second-order correlation energy was derived for a system under the spin-dependent perturbations, and it was applied to the correlated calculation of the 3JHH's in ethane, methanol, and methylamine. The calculation showed that the addition of tight s-type functions to the basis set considerably affects the Fermi contact (FC) contribution. Furthermore, the third- and fourth-order correlations were also evaluated for the FC contribution with the finite perturbation theory. The three noncontact contributions were computed at the Hartree–Fock (HF) level. The total contribution to the 3JHH in ethane was significantly lower than the experimental value. The calculated 3JHH's in methanol and methylamine were nearer to the experimental couplings than in ethane. © 2000 American Institute of Physics.

    Nanometer-scale resolution of a chloromethylated calixarene negative resist in electron-beam lithography: Dependence on the number of phenolic residues (2000)

    Notes: We have investigated a chloromethylated calixarene, p-chloromethylmethoxcalix[n]arene (CMC[n]AOMe) (n=5,6,7), as a negative resist in electron-beam lithography. Each CMC[n]AOMe resist has a resolution of about 12 nm and a sensitivity of about 0.8 mC/cm2 which varies slightly with n (or molecular weight). A sub-10-nm Si wire has been fabricated by halide plasma etching and a CMC[n]AOMe resist as an etching mask. Because the resist pattern edge is smooth, Si wires with 7-nm width and 10-μm length were performed without any breaking. © 2000 American Institute of Physics.

    Characteristic length of hot-electron transport in silicon metal–oxide–semiconductor field-effect transistors (2000)

    Notes: Characteristic length of hot-electron transport in an inversion layer at a Si surface is estimated by using lateral hot electron transistor, which has an upper gate and two lower gates. The inversion layer formed by biasing the upper-gate voltage is separated into three channel regions (the emitter, collector, and base) by the two lower gates. We find that the characteristic length depends on both the upper-gate voltage and the injection energy and ranges from 19 to 27 nm. These results show that hot electrons are affected by electron–electron scattering or surface–roughness scattering and that hot-electron transport plays a crucial role in Si metal–oxide–semiconductor field effect transistors with gate lengths of 20 nm or less. © 2000 American Institute of Physics.

    Cell-mediated protection in carp, Cyprinus carpio L., against Aeromonas hydrophila (1988)

    Notes: Abstract. The mechanism of protection against Aeromonas hydrophila infection in carp was studied. Recipient fish, into which pronephric cells from carp previously immunized by dipping in bacterial crude lipopolysaccharide (LPS) at 25°C for 2h were transferred, demonstrated almost the same level of protective ability as an immunized control group. The protective ability was transmitted by non-adherent (to nylon fibre) immune pronephric cells. These non-adherent cells were damaged by anti-carp thymocyte serum and were, thus, considered to be T-like cells. The protective ability was depressed in immunized carp treated with anti-carp thymocyte serum in vivo and was also remarkably reduced in immunized carp whose macrophage function was impaired by Dextran sulphate-500 treatment. These results indicate that the protection shown by carp immunized by dipping in crude LPS is dependent on cellular immunity regulated by a T-like cell-macrophage system.

    Immune protection in carp, Cyprinus carpio L., after immunization with Aeromonas hydrophila crude lipopolysaccharide (1988)

    Notes: Abstract. Vaccination with crude lipopolysaccharide (LPS) induced better protection against infection with Aeromonas hydrophila in carp than vaccination with formalin killed vaccine. Dipping fish in vaccine for 2 h at 25°C was more effective than intraperitoneal injection of the vaccine in procedural simplicity, lower stress loading and the degree of protection acquired. In carp immunized with crude LPS by the dip method, antibodies were not detected by bacteriai agglutination, passive haemagglutination and the agar diffusion tests. The results indicate that the protection against A. hydrophila infection in carp is not dependent on humoral immunity.

    A case of unilateral dermatomal cavernous haemangiomatosis (2000)

    Notes: We report a 39-year-old man with unilateral dermatomal cavernous haemangiomatosis (UDCH). Clinically, three haemangiomas were unilaterally distributed in the C6 dermatome. Histologically, these haemangiomas were distinct from routine cavernous haemangioma in that hyperplasia of smooth muscle cells on the vascular wall was observed, and electron microscopy showed that smooth muscle cells contained myofilaments and a crystal-like structure in the endothelial cells. This is distinct from Weibel–Palade bodies, which are rod-shaped cytoplasmic organelles measuring approximately 0·1 µm in diameter with a parallel linear structure. In UDCH, the haemangiomas occur only in the skin. They are clinically and histologically similar to those of blue rubber bleb naevus syndrome (BRBNS), but in BRBNS there are multiple haemangiomas in the digestive tract and other organs. UDCH is distinct from Maffucci syndrome in that enchondromata and malignant tumours are absent. To our knowledge, this is the second case of UDCH reported in the literature.

    Restoration of Mineral Depositions by Dexamethasone in the Matrix of Nonmineralizing Osteoblastic Cells Subcloned from MC3T3-E1 Cells (2000)

    Notes: Abstract. The original osteoblastic cell line, MC3T3-E1, was derived from normal mouse bone tissue and mineralized without any specific factors in vitro. This cell line may be slightly unstable because of high differentiation, and some of these cells sometimes lost the ability for mineral deposition. In this study, a new cell line was cloned which lost the ability for mineral deposition from MC3T3-E1 cells. This cell line, termed MC3T3-NM4, was not observed to undergo mineral deposition for up to at least 36 days even in media containing beta-glycerophosphate. The alkaline phosphatase (ALP) activity was also not increased. The lack of calcifying ability was found to be restored by the addition of dexamethasone in the media. This restoration was accompanied by an increase in ALP activity and osteocalcin level. It was suggested that this restoration was not due to artificial mineralization resulting from cell death.
