    Notes: In our previous study, apparent reduction of glucocorticoid receptor (GR) mRNA was seen in the hippocampus and the hypothalamic paraventricular nucleus (PVN) during repeated immobilization (IMO) stress, but not following starvation. Our laboratory has also shown that the sp1 activates, whereas tumour suppressor p53 represses the promoter activity of GR gene. In an attempt to reveal the possibility that transcription factors such as sp1 and/or p53 are involved in the regulation of GR mRNA expression in the hippocampus and in the PVN in vivo, we examined the expression of GR mRNA, p53 mRNA, and sp1 mRNA in the hippocampus and in the PVN during repeated IMO and following starvation. In addition, the expression of these mRNAs was examined in the anterior pituitary, another GR-rich area. GR mRNA in all subfields of the hippocampus was robustly decreased, while GR mRNA in the anterior pituitary was increased, 24 h following 4 × IMO (2 h daily, for 4 consecutive days) and immediately after 5 × IMO. GR mRNA in the PVN was significantly decreased immediately after 5 × IMO, but not at 24 h after 4 × IMO. Conversely, p53 mRNA in the PVN and hippocampus was increased, whereas p53 mRNA in the anterior pituitary was decreased, 24 h following 4 × IMO and immediately after 5 × IMO. Sp1 mRNA was unchanged in all areas examined following repeated IMO. Following 4 days of starvation, neither GR mRNA, p53 mRNA nor sp1 mRNA showed any changes in the PVN and the hippocampus, except there was a minor decrease in GR mRNA in CA1-2. In the anterior pituitary, 4 days of starvation induced a minor, but significant increase in GR mRNA, whereas it decreased p53 mRNA. Overall, regression analyses revealed a negative correlation between GR mRNA levels and p53 mRNA levels in CA1-2 and dentate gyrus of the hippocampus and in the anterior pituitary. GR mRNA in the PVN also showed a tendency towards the negative correlation with p53 mRNA levels. The results raise the possibility that p53 negatively regulates GR mRNA expression in the PVN, the hippocampus and the anterior pituitary during repeated immobilization stress.

    Notes: SUMMARY —Basic, phenolic and lactonic fractions of the fusel oils obtained from Japanese and Scotch whiskies were analyzed mainly by means of gas-liquid chromatography coupled with mass spectrometry. Two picolines, three lutidines, two ethyl pyridines, α-isopropyl and 2-methyl-5-ethyl pyridines, quinoline, 2- and 6-methyl quinolines, eight pyrazines, guaiacol and its three alkyl derivatives, phenol, two ethyl phenols, o-isopropyl phenol, two cresols, 2,6-xylenol, eugenol, o-hydroxy acetophenone, 2-hydroxy-5-methyl acetophenone, γ-nonalactone, cis- and trans-3-methyl-4-hydroxy caprylic acid γ-lactone and five furan compounds were found in Japanese or Scotch whiskies. Origins of these compounds are discussed.

    Notes: We describe a 68-year-old healthy woman with an unusual skin manifestation of mycetoma. A dark reddish erythematous plaque was present on the dorsum of the left hand for over 10 years. A skin biopsy revealed sulphur granules in the abscess, and Nocardia nova was identified from the specimen. Treatment with dapsone resulted in significant improvement. We review the clinical features of cutaneous N. nova infections.

    Notes: Abstract A naturally occurring member of ubiquinone (Q) group, a dihydroubiquinone-9 (Q-9 (H2)), has been isolated as a minor ubiquinone component from the fungus Aureobasidium pullulans. By ultraviolet absorption, mass and nuclear magnetic resonance spectrometric studies, the structure of Q-9 (H2) was found to be 2,3-dimethoxy-5-methyl-6-IX-dihydromultiprenyl9-1,4-benzoquinone (I).

    Notes: Abstract A Cournot model with an arbitrary nonlinear demand function and where firms do notobserve their rival's actions directly is shown to allow mistaken beliefs to persist. Thesealter the original equilibrium state and, in a range of beliefs, destroy its stability and createcycles. The dynamics of the Cournot model are therefore fundamentally affected.

    Notes: Abstract We formulate a class of dynamic games which consists of so‐called capital accumulationgames. In such games, rival firms invest strategically in a stock of physical capital. Thecapital stocks of all firms in the industry are the state variables of the game and firms usethe rate of change of the capital stocks as their control variables. It is assumed that currentprofits of a firm are not only dependent on the firm's own capital stock, but also on thestock of capital of the rival firm. We prove existence of multiple Markov Perfect Equilibria(MPE) and study their qualitative characteristics. It turns out that there exist two differenttypes of equilibria: a strict equilibrium that is degenerate and coincides with the uniqueopen‐loop one and so‐called indifferent equilibria that are non‐strict. For both types, westudy the equilibrium dynamics. While the strict equilibrium is characterized by simpleequilibrium dynamics, the indifferent equilibria may exhibit complex dynamic behaviour.

    Notes: Abstract. —We examine the applicability of conditional stochastic simulation to interpretation of microseisms observed on soft soil sediments at Kushiro, Hokkaido, Japan. The theory of conditional random fields developed by Kameda and Morikawa (1994) is used, which allows one to perform interpolation of a Gaussian stochastic time-space field that is conditioned by realized values of time functions specified at some discrete locations. The applicability is examined by a blind test, that is, by comparing a set of simulated seismograms and recorded ones obtained from three-point array observa tions. A test of fitness was performed by means of the sign test. It is concluded that the method is applicable to interpretation of microseisms, and that the wave field of microseisms can be treated as Gaussian random fields both in time and space.

    Notes: Abstract A rapid-frequency-scan dye laser was developed for the measurement of the velocity-distribution functions of impurity atoms sputtered due to the high-temperature plasma-surface interaction. In order to confirm the effectiveness of this rapid-scan technique, measurements of the Doppler profiles of Fe atoms sputtered by Ar ion-beam bombardment with energy 3 keV were performed. A scanning range of more than 40 pm at λ ≈300 nm was obtained with a spectral bandwidth of 1.5 ∼2 pm and good linearity. Doppler profiles were determined in various scattering conditions, and excellent performance of this technique was demonstrated. The distortion error caused by line saturation was analytically discussed, and it is shown that the effect of this error is not so serious (less than 10%) even for highly saturated excitation.

    Notes: Abstract Three dimensional granular flow experiments were carried out on a ski jump with 300,000 ping-pong balls. Since the air drag was a large effect, the flow arrived at a steady state within a short distance. The terminal velocities attained showed a remarkable increase with the number of released balls. In addition, the flow formed a distinct head and tail structure, which has often been observed in large-scale geophysical flows in nature. Similarity analysis is used to show that the experiment corresponds to a natural snow avalanche that runs for several kilometers. Video cameras positioned above the flow allowed the measurement of the location and the distance of a single ball, which finally led to the particle velocity profiles. The static pressure depression measurements in and above the flow showed the air velocity profiles and suggested the strong interaction between the balls and the surrounding fluid(air). Computer simulation of 3-dimensional, inhomogeneous two-phase flows that uses the DEM for the particles and the Reynolds-averaged Navier Stokes equations for the fluid are currently in progress.

    Notes: Abstract Mitochondrial DNA (mtDNA) diversity was investigated in 38 isolants ofCladosporium carrionii in Africa (3 isolants), Australia (10), China (15) and Venezuela (10).C. carrionii was classified into 4 mtDNA types (Type I to Type IV) based on the restriction patterns withMspI,Sau3AI andHaeIII. All the 15 strains in China and 9 of 10 strains in Venezuela showed Type I, while all the 10 strains in Australia showed Type II. These results suggested a correlation between the mtDNA types and geographic origin.
