    Notes: Analogous to the localization of the wave function of an electron in a random potential (Anderson localization), in the macroscopic system of magnetoelastic waves (MEWs) propagating in a highly magnetostrictive string exhibiting the giant ΔE effect, the piling-up of MEWs into a wave-packet in a restricted small region of the string is expected. This wave-packet is subject to hopping in a discontinuous wave by applying a magnetic field due to the change in the local elastic states caused by the ΔE effect. From this expectation, a theoretical analysis was performed focusing on the derivation of localization conditions of MEWs. The analysis was carried out using a one-dimensional string model having high magnetostriction. The string is assumed to be composed of random chains with (1) alloy-type disorder (random weights of masses with equal spacings) and (2) liquid-type disorder (random spacings of masses with equal weights). For the elastic and magnetoelastic constants of the string, the value of Fe78Si10B12 amorphous wire (Unitika) were used in the calculations. No substantial changes in the localization states were not recognized in both modes. The analysis revealed that, when the change of the apparent Young's modulus with magnetic field ΔE is 28%, the localized MEWs are subject to hopping conserving their wave identities (eigenfrequencies and eigenstates). This result in considered to originate from the changes in the disorder conditions to support the localization of MEWs. To confirm the above theoretical prediction experimentally, MEW properties have been measured by using Fe78Si10B12 amorphous wires connecting weights made of leads to form the random chain structure. The localized MEWs are, indeed, observed by detecting the local vibrations of the wires. Theoretical and experimental results will be presented in detail at the conference. © 1997 American Institute of Physics.

    Notes: Charged particles in organic polymer plumes photoablated by ultraviolet lasers are measured with a Faraday cup assembly. In spite of a relatively low F2 laser (157 nm) fluence 〈1 J/cm2, relative charged fragment concentrations measured for polyimide, polytetrafluoroethylene, and polyethyleneterephthalate targets are (approximately-greater-than)10−3. Charged particle concentrations in the ablation plumes generated by an F2 laser with polyethyleneterephthalate and polyimide targets are always higher than those in KrF laser (248 nm) ablation plumes at the same specific laser energy deposited on the target. Charged fragments have also higher velocities in the F2 laser ablation plumes. An exponential increase in the charged fragment concentration with increasing laser fluence suggests that the ions are mainly produced through electron-neutral collisions in the hot material core close to the target surface. © 1995 American Institute of Physics.

    Notes: Organic thin films of copper-phthalocyanine (CuPc) and aluminum tris-8-hydroxyquinline (Alq3) were fabricated via KrF laser ablation. In spite of poor crystallinity exhibited in the reconstructed organic films, the CuPc film still works as a hole-transport layer in electroluminescence cells based on the CuPc and Alq3 layers. Electroluminescence at ∼500 nm was obtained with a low initiation voltage of ∼12 V. There is no significant difference in electroluminescence performance for devices fabricated via laser ablation and thermal evaporation. Emission at ∼600 nm caused by energy transfer from Alq3 to 4-(Dicyanomethylene)-2-methyl-6-(p-dimethylaminostyryl)-4H-pyran (DCM) is also observed from a DCM-doped Alq3 emission layer. © 1997 American Institute of Physics.

    Notes: We have developed a very controllable fabrication process of an extremely narrow (∼10 nm) quantum wire metal-oxide-semiconductor field-effect transistor (MOSFET) on a separation-by-implanted-oxygen (SIMOX) substrate using anisotropic etching and selective oxidation technique. The drain current versus gate voltage characteristics show oscillations caused by Coulomb blockade even at room temperature. The oscillations split into several sharp peaks when the temperature is decreased, indicating that the channel is separated by several serial coupled quantum dots and that the quantum levels of these dots correspond to the observed fine peaks. © 1996 American Institute of Physics.

    Notes: 1. The antihypertensive effects of 10 mg/kg trichloromethiazide (TCM), 10 mg/kg 7–O-ethylfangchinoline (7–O-EFC) and the combination of these drugs given orally once daily for 2 weeks were investigated by measuring the blood pressure (BP), heart rate (HR) and activity in conscious, freely moving spontaneously hypertensive rats (SHR) fitted with a telemetry device.2. Clear diurnal rhythms of the HR and activity in synchrony with the light/dark cycle were observed during therapy, whereas the BP rhythm was obscure.3. Alone, TCM and 7–O-EFC produced slight and insignificant reductions of 24 h mean BP, whereas in combination they produced an additive and significant BP reduction, compared with the vehicle-treated controls, from the third day of therapy. The BP reduction induced by the combination of these drugs during the dark phase was more marked than that during the light phase.4. None of the drug therapies affected the HR and activity diurnal rhythms.5. The results of the present study demonstrate that the telemetry method is useful for monitoring the antihypertensive effects of drugs in SHR under physiological conditions with minimal stress.

    Notes: 1. The depressor response to sodium nitroprusside (SNP) and the pressor response to Nω-nitro-L-arginine methyl ester (L-NAME) were investigated in anaesthetized and ganglion-blocked 6 week old (young) and 20 week old (adult) spontaneously hypertensive rats (SHR), and the results were compared with those in age-matched normotensive Wistar-Kyoto (WKY) rats.2. SNP produced a dose-dependent decrease of the mean blood pressure (BP) in both strains, and no differences in vascular sensitivity to SNP were observed between the strains.3. L-NAME caused dose-dependent pressor responses in both strains. The sensitivity and the maximal response to L-NAME in SHR were significantly greater than those in age-matched WKY (P 〈 0.05 or 0.01; t-test, 13d.f. in both ages). However, there were no significant differences in the responses between ages in each strain.4. Acute reduction of BP induced by 7-O-ethylfangchinoline did not affect the responses to SNP and L-NAME in the adult SHR.5. These results indicate that a greater amount of NO is tonically released in SHR and that its contribution to BP control is greater in SHR than in WKY, whereas vascular sensitivity to NO does not differ between the strains. In addition, acute changes in BP do not affect the degree of dependency on NO for BP control.

    Notes: To establish whether MIB-1 and p53 staining are useful for differentiating pilocytic astrocytomas and astrocytomas from anaplastic astrocytomas and glioblastomas. This study was restricted to children and young adults under 30 years of age because of the differences in p53 mutations between paediatric and adult astrocytomas.〈section xml:id="abs1-2"〉〈title type="main"〉Methods and resultsForty-five astrocytic tumours, including 18 pilocytic astrocytomas, 14 astrocytomas, four anaplastic astrocytomas and nine glioblastomas, from 45 children and young adults, between 1 and 29 years (mean 11 years) of age, were examined pathologically, and sections from paraffin-embedded blocks were used for MIB-1 and p53 immunostaining. The MIB-1 labelling index and the frequency and intensity of p53 staining in both the pilocytic astrocytoma and the astrocytoma group were significantly lower than in the anaplastic astrocytoma plus glioblastoma group (P 〈 0.001). In 11.1% (two of 18) of pilocytic astrocytomas and 42.9% (six of 14) of astrocytomas, immunoreactivity of either MIB-1 or p53 staining was of almost the same intensity as that of anaplastic astrocytomas and glioblastomas. However, in these cases, results using both MIB-1 and p53 stain differed from those for anaplastic astrocytomas and glioblastomas.〈section xml:id="abs1-3"〉〈title type="main"〉ConclusionsMIB-1 and p53 co-staining is very useful for differentiating pilocytic astrocytomas and astrocytomas from anaplastic astrocytomas and glioblastomas. However, MIB-1 or p53 staining alone cannot differentiate pilocytic astrocytomas and astrocytomas from anaplastic astrocytomas and glioblastomas.

    Notes: Growth of Escherichia coli and Staphylococcus aureuson the surface of Trypticase Soy Agar (TSA) packaged with various CO2 partial pressures (0, 20, 40, 60, 80, 100%, balance N2) was compared to the control (N2 100%) on TSA in which the pH was adjusted to equal that in CO2 atmospheres at 15°C and 30°C. At 15°C, the biostatic effect was noted with all CO2 partial pressures for both species. At 30°C, the biostatic effect of CO2 was almost completely nullified for E. coli, but that for S. aureus was still effective. S. aureus was more sensitive to the inhibitory effects of CO2 than E. coli at both the temperatures.

    Notes: Improving daily-life habits is considered to be effective in treating obesity. We have examined obesity in regular physical examinations in university students since 1974. In this study, the subjects were 199 students regarded as obese (Broca's index: more than 120%) and 326 non-obese students randomly selected (525 subjects in total) among students who underwent regular physical examinations at Nagoya University, Japan, between 1974 and 1978. Here we report our follow-up survey of obese university students and non-obese individuals who were students of the same university during the same period. This study was carried out for the purpose of clarifying the relationship between changes in lifestyle and body weight 20 years after graduation. Concerning eating behavior, a higher proportion of subjects cared about diet intake in the current non-obese group than in the current obese group (P 〈 0.05). The meal-time in the obese was shorter than that in the non-obese group (P 〈 0.01). Ten percent of subjects in the obese group and 24.4% of subjects in the non-obese group selected class II (moderate) or higher as indicative of the intensity of their daily physical activity. There was a significant difference in distribution between the groups (P 〈 0.05). In the group showing improvement in obesity over time, a higher proportion of subjects cared about diet intake than in the group with continued obesity (P 〈 0.05). Concerning intensity of physical activity, 11.8% of subjects in the group with continued obesity selected class II (moderate) or higher, while 45.5% of subjects in the group showing improvement in obesity chose class II (moderate) or higher. A significant difference in distribution existed between the groups (P 〈 0.01). These findings suggest that the eating behavior of ending meals before feeling satiety and a lifestyle change to enhance the intensity of daily physical activity including walking, even if not having any special sports habits, are effective in decreasing body weight.

    Notes: Abstract To investigate the effect of fructose ingestion on sorbitol and fructose 3-phosphate (F3P) in erythrocytes, we administered 50 g fructose with and without treatment with an aldose reductase inhibitor, epalrestat, to seven healthy, normal-glucose-tolerant, male volunteers aged 20–43 years. The same subjects were given 50 g glucose on another day. The sorbitol and F3P contents in their erythrocytes increased significantly, reaching peak levels at 60 min and 180 min, respectively, following fructose ingestion. On the other hand, glucose ingestion did not cause any statistically significant change in sorbitol content in their erythrocytes, although it significantly elevated their F3P content. Treatment with epalrestat had no significant effect on incremental changes in erythrocyte sorbitol and F3P content following fructose ingestion. This suggests that oral fructose may be converted directly to sorbitol and F3P in erythrocytes instead of being converted via glucose. Thus, the dietary intake of fructose may affect the concentrations of sorbitol and F3P in erythrocytes in normal men.
