    Notes: Abstract Thiazin red (TR), a fluorochrome that has an affinity to fibrillary structures such as neurofibrillary tangles (NFTs) or senile plaques, was utilized to investigate assembly of tau protein into fibrils in tau-immunopositive neocortical neurons of corticobasal degeneration (CBD) and of Alzheimer’s disease (AD). Double fluorescence with anti-paired helical filament monoclonal antibody (AT8) and TR was followed by either the Gallyas or Bodian silver impregnation method, which enabled a comparison of the staining features by three different methods on the same neuron. NFTs of AD were uniformly stained by TR and Gallyas method. Most of tau-immunopositive neurons of CBD were similarly stained by Gallyas method but barely or only weakly by TR or Bodian method, suggesting that tau in neocortical neurons of CBD is less liable to form fibrillary structures than in those of AD, easily distinguishable by TR staining. Clarifying the process of tau assembly using this fluorochrome will give a clue to understanding mechanisms of tau deposition, which may be different in various neurological disorders.

    Lancefield group C Streptococcus dysgalactiae infection responsible for fish mortalities in Japan (2004)

    Notes: A Lancefield serological group C Streptococcus sp. was isolated from cultured amberjack, Seriola dumerili Risso, and yellowtail, Seriola quinqueradiata Temminck and Schlegel, immunized with Lactococcus garvieae commercial vaccines in Japan. The isolated bacteria were Gram-positive cocci, auto-aggregating in saline, morphologically long chains in growth medium, catalase negative and α-haemolytic on blood agar. An almost complete gene sequence of the 16S rDNA of two isolates was determined and compared with that of bacterial strains in the database. The isolates were identified as Streptococcus dysgalactiae based on the results of the 16S rDNA sequence, the bacteriological properties and the Lancefield serological grouping. Oligonucleotide primers specifically designed for the 16S–23S rDNA intergenic spacer region of S. dysgalactiae amplified a gene from all the fish isolates, as well as the type strains α-haemolytic S. dysgalactiae subsp. dysgalactiae ATCC430738 and β-haemolytic S. dysgalactiae subsp. equisimilis ATCC35666, but not those of S. equi ATCC33398, Lactococcus garvieae ATCC43921 and L. garvieae KG9408. The severe necrotic lesions of the caudal peduncle seen in experimentally infected fish were similar to those seen in naturally infected fish.

    Three-color polymer light-emitting diodes by stamped dye diffusion (2002)

    Notes: A method to pattern the integrated emissive colors of polymer light-emitting diodes (PLEDs) using stamped dye diffusion is introduced. In this method, the emitting colors are tuned selectively by the energy transfer processes from the host polymer to the diffused dye. The diffusion of the dye into the emitting polymer layer was successfully achieved by transferring the prefabricated dye pattern onto a silicon substrate at an elevated temperature. Coumarin6, 4-(dicyanomethylene)2-methyl-6-(1,1,7,7-tetramethyljulolidyl-9-enyl)-4H-pyran and Nile Red dyes were diffused selectively into a poly (9-vinylcarbazole)-based emitting layer using this method. We have investigated the electroluminescent properties of the dye diffused PLEDs and also have demonstrated the integration of three-color PLEDs with dimensions of the order of 10 μm. © 2002 American Institute of Physics.

    Notes: We have investigated the morphologies and gap energies of In0.46Ga0.54As quantum dots (QDs) by using scanning tunneling microscopy/spectroscopy. The measured gap energy increases with decreasing dot height in the range of 1.7–6.6 nm. The gap energy has been calculated using a one-dimensional quantum well model taking into account a variation of In composition. Comparison of the observed height dependence and the calculation indicates the one-dimensional quantum confinement of carriers and the In enrichment in a QD. © 2001 American Institute of Physics.

    Notes: Scanning tunneling spectroscopy has been used to study quantum-size effects on the electronic structure of InAs quantum dots (QDs) in correlation with their morphologies. The measured gap energy increases with decreasing dot height in the range of 3.4–7.6 nm. Comparison between the observed height dependence and calculation based on a quantum disk model indicates that the gap energy of a single InAs QD is mainly determined by the quantum confinement in the vertical direction of the QD. © 2000 American Institute of Physics.

    Involvement of the Entorhinal Cortex in the Stress Response to Immobilization, But Not to Insulin-Induced Hypoglycaemia (2003)

    Notes: Although the involvement of the limbic system in the neuroendocrine responses to some stressors has been documented, the specific role of the entorhinal cortex has not been elucidated. In this study, we investigated the involvement of the entorhinal cortex in stress responses. Fos immunoreactivity, a widely used marker for neuronal activation, was detected in the entorhinal cortex of rats subjected to immobilization stress, whereas no marked staining was observed in the entorhinal cortex of the control and insulin-induced hypoglycaemia groups. Lesion of the entorhinal cortex produced by ibotenic acid significantly attenuated the adrenocorticotropic hormone (ACTH) release evoked by immobilization; however, no significant change in ACTH release was observed in insulin-induced hypoglycaemia. No significant difference between entorhinal-lesioned rats and control rats was observed in blood glucose concentrations when subjected to either immobilization or to insulin-induced hypoglycaemia. Together, these results indicate that the entorhinal cortex is closely involved in the stress response to immobilization but not to insulin-induced hypoglycaemia.

    Compressible bag model and the phase structure (2002)

    Notes: Abstract. The phase structure of hadrons and the quark-gluon plasma is investigated by two types of equation of state of the hadrons, namely the ideal hadron gas model and the compressible bag model. It is pointed out that, while the ideal gas model produces an unrealistic extra hadron phase, the compressible bag model gives the expected and reasonable phase diagram even if the rich hadron spectrum is taken into account.

    Notes: Abstract We investigated to measure the objective visual acuity using pattern visual evoked potentials (PVEP) to help the diagnosis with psychogenic visual loss (PVL) who ranged in age from 7 to 14 years old. Pattern stimuli consisted of black and white checkerboard patterns (39, 26, 15 and 9′) with a visual angle of 8 degrees and a contrast level of 15%. The pattern reversal frequency was 0.7 Hz. This resulted in an average of 100 PVEP per session. Visual acuity of 0.1 was consistent with the 39′ pattern, 0.2 with the 26′ pattern, 0.5 with the 15′ pattern, and 1.0 with the 9′ pattern. As the results, five PVL patients could measure visual acuity with this method in the present study. The PVEP is useful in evaluating the visual acuity and helped to diagnose the PVL patients. In addition we used the dynamic topography to study the difference in the results of the PVEP. The dynamic topography obtained from the results of the PVEP was analyzed. The flow type of the P100 component diverged into three types (separated type, hollow type and localized type) in the PVL patients and the normal children. The localized type was observed in 59.1% of normal children and in 56.3% of PVL patients. While the separated type was shown in 6.8% of normal children and in 8.3% of PVL patients. There were not significant differences between the PVL patients and the normal children in each type.
