    Notes: The new frames in physics has united the physics of materials and a new terminology of supercorresponding c- and q-number systems is introduced for the classical and quantal physics. In the q-number system, the electron field as represented by the Schrödinger or Dirac wave function is regarded as the electron itself, which interacts with the zero-point photon field and gives the mass renormalization. The new frames can analyze this subject without the divergence difficulty. The resultant decrease in the self-energy of the electron of about 1 eV is proposed to be dependent on the environmental crystal situation, and may become cooperative to generate coherence to the conduction electron-photon coupled system. Our basic c-number equation includes the vector potential of the interacting photon field, the microscopic electronic electric current, the frequency of the considered photon field, the original plasma frequency of the conduction electrons, and an equivalent frequency and the resonance frequency of the bound-state electrons. Placing reasonable values for these constants, we get a detailed k-ω diagram for the photon-electron field complex. By the action of the bound-state electrons, the original plasma frequency of about 4 eV is separated into two, with the lower value of about 1.7 eV (2.6×1015 s−1). This branch crosses the free-photon mode near the same frequency, opening a sharp narrow window for the zero-point free-photon field. The Fermi frequency of the conduction electrons is about the same with the wavelength of about 10 A(ring), which may fit one of the crystal dimensions. The zero-point photon-electron field complex at this frequency may couple to the electron field at the Fermi level through the induced zero-point ripple electron field. The Heisenberg uncertainty, ΔEΔt≥(h-dash-bar), may operate to the window for generating the longer time-space coherence. We call this mechanism CRCG (crystallo-radiative coherence generator).

    Voltage shift phenomena in a heteroepitaxial BaTiO3 thin film capacitor (2002)

    Notes: Voltage shift phenomena of the hysteresis loop were characterized for a c-axis oriented heteroepitaxial BaTiO3 film by means of switching current measurements using various types of pulse sequences. During application of voltage, the hysteresis loop gradually shifted along the voltage axis according to the polarity of the voltage. Even after the application of voltage, while the top and bottom electrodes were short-circuited, the hysteresis loop continued to move. Under certain conditions, a part of the hysteresis loop shifted back, whereas the rest shifted forward. These results were explained, assuming that there is a nonswitching layer between the ferroelectric layer and the bottom electrode, and that the discontinuity of polarization can be compensated by injection of negative charges from the electrode. It was suggested that the nonswitching layer is possibly formed by relaxation of lattice misfit strain in the heteroepitaxial ferroelectric thin film. © 2002 American Institute of Physics.

    Reduction of HSP70 and HSC70 Heat Shock mRNA Induction by Pentobarbital After Transient Global Ischemia in Gerbil Brain (1993)

    Notes: Abstract: The effect of pentobarbital on the induction of heat shock protein (HSP) 70 and heat shock cognate protein (HSC) 70 mRNAs after transient global ischemia in gerbil brains was investigated by in situ hybridization using cloned cDNA probes selective for each mRNA species. In sham control brains, HSP70 mRNA was scarcely present, whereas HSC70 mRNA was present in most cell populations. After a 5-min occlusion of bilateral common carotid arteries, HSP70 and HSC70 mRNAs were induced together in several cells and were especially dense in hippocampal dentate granule cells at 3 h, but the strong hybridization of the mRNAs continued only in hippocampal CA1 cells by 2 days. At 7 days after the ischemia, CA1 neuronal cell death was apparent, and the HSP70 mRNA disappeared and HSC70 mRNA content returned to the sham level, except for in the CA1 cells. Pretreatment with pentobarbital (40 mg/kg, i.p.) greatly reduced or inhibited the induction of HSP70 and HSC70 mRNAs at both early (3-h) and late (2-day) phases after ischemia. The drug also prevented CA1 cell death at 7 days along with the maintenance of expression of HSC70 mRNA at the sham control level. Hypothermic effects of pentobarbital were noted at 30 and 60 min after the reperfusion, whereas at 2 h there was no statistical significance between the control and drug-treated groups. The great reduction of HSP70 and HSC70 mRNA induction at both early and late phases after ischemia suggests that pentobarbital reduces intra- and/or postischemic stress and may protect CA1 cells from ischemic damage. These effects of the drug may be mainly due to its specific action rather than its hypothermic effects.

    Notes: Background: A definite threshold of the peripheral blood eosinophile count that indicates the presence of hypereosinophilia-associated diseases has not yet been determined.Methods: The threshold eosinophile count at which cases of hypereosinophilia-associated diseases (n = 25) can be differentiated from those of bronchial asthma (n = 101) was determined. Then, the incidences of eosinophile counts greater than 1.0 × 109/l or the threshold level, were studied by analysis of 43 805 samples sent to the laboratory, and the diseases associated with the increased counts were determined.Results: The eosinophile count in cases of hypereosinophilia-associated diseases and in those of bronchial asthma were 10.967 ± 1.680 × 109/l and 0.574 ± 0.045 × 109/l, respectively (P 〈 0.001); the threshold was 2.052 × 109/l. The percentages of samples with an eosinophile count of more than 1.0 × 109/l and 2.052 × 109/l were 0.6% and 0.1%, respectively; the latter comprised of 41 samples from 24 patients including eight with hypereosinophilia-associated diseases. The patients with hypereosinophilia-associated diseases had a significantly higher count, and a higher incidence of counts of more than 2.052 × 109/l, than others, including patients with malignancies and symptoms conventionally referred as “atopic diseases”.Conclusion: Hypereosinophilia-associated diseases are associated with a very high eosinophile count of more than 2.052 × 109/l, which was observed rarely.

    Notes: Activity of fish muscle glutathione peroxidase, which presumably protects muscle from oxidative deterioration during storage and processing, was found in both Japanese jack mackerel and skipjack tuna. Activity of the peroxidase and level of reduced glutathione (enzyme substrate) decreased during 5 days storage at 4°C. Lipid hydroperoxides were substantially formed in the fish muscles during the storage.

    Notes: Background: Th2 cells are thought to be involved in eosinophilic inflammation of the lung. CC chemokine receptor 4 (CCR4) has been identified as a specific receptor for both thymus and activation-regulated chemokine (TARC) and macrophage-derived chemokine (MDC), and is preferentially expressed on Th2 cells.Objective: Our aim was to evaluate the role of Th2 cells in the lung of patients with eosinophilic pneumonia (EP).Methods: The concentrations of TARC, MDC, and interleukin (IL)-5 were measured in bronchoalveolar lavage fluid (BALF) by ELISA. Proportion of CCR4-expressing CD4+ T cells (CCR4+ CD4+ T cells) was determined by flow cytometry.Results: TARC and MDC concentrations in BALF were higher in patients with EP than in normal subjects. The proportion of CCR4-expressing cells among CD4+ T cells was higher in BALF than in peripheral blood of patients with EP. There was a significant correlation between the number of CCR4+ CD4+ T cells and the levels of TARC, MDC, and IL-5 in BALF of patients with EP.Conclusions: Our data suggest that Th2 cells, which express CCR4 and its ligands (TARC and MDC), contribute to the pathogenesis of EP in the lung.

    Notes: 〈list xml:id="l1" style="custom"〉1The age-related changes in mean arterial pressure (MAP), heart rate (HR), and baroreflex sensitivity (BRS) were studied in spontaneously hypertensive rats (SHR) and Wistar-Kyoto (WKY) rats from 4 to 20 weeks of age.2Intra-arterial blood pressure (BP) was continuously recorded for 24 h in conscious, freely moving rats. Twenty-four hour MAP and HR were calculated by an online computer. Baroreflex sensitivity was measured by phenylephrine infusion.3In SHR, BRS was significantly lower than in WKY as early as 4-5 weeks, at which time MAP in SHR was only slightly raised. During subsequent weeks, rapid increase in MAP occurred in SHR, in association with progressive bradycardia.4It was concluded that a reduced BRS may be detected in young prehypertensive SHR and this impairment of BRS may be central in origin.

    Masticatory movement in two cases with unusual alignment of the maxillary canine (2000)

    Notes: Masticatory function was analysed before and after orthodontic treatment in two cases where tooth alignment remained unusual after treatment. The Sirognathograph Analyzing System® was used to analyse the masticatory function. In both cases, the right maxillary first premolar was located where the maxillary canine is normally positioned. The results of orthodontic treatment were satisfactory both morphologically and aesthetically, and masticatory function was greatly improved. However, some problems remained in the mandibular movement due to the abnormal contact between the mandibular teeth and the maxillary first premolar. These findings support the need for examination of masticatory function when treating patients with an unusual tooth alignment even if the results of orthodontic treatment are both morphologically and aesthetically successful.

    Notes: Soybean (Glycine max) cv. Harosoy 63 is resistant to race 1 and susceptible to race 9 of Phytophthora megasperma f. sp. glycinea (Pmg). In detached primary leaves inoculated with zoospores, growth of race 1 was completely suppressed 16 h after inoculation, while race 9 was unaffected. The amount of the phytoalexin glyceollin that accumulated, however, was not significantly different in either the incompatible or compatible interaction 16 h after inoculation. At the circumference of the inoculated area, a slight accumulation of phytoalexin was observed only in the incompatible interaction 20 h or more after inoculation. Tolerance of race 9 to the phytoalexin was significantly higher than that of race 1 when the phytoalexin was added to agar. Moreover, race 9 degraded glyceollin faster than race 1. On leaves inoculated at separate points with either race, the lesion associated with race 9 never colonized areas inoculated with race 1. These results suggest that factor(s) other than the accumulation of phytoalexin in soybean tissue might cause cessation of growth of Pmg.
