- Abstract
Context. The presence of the lithium-6 isotope in some metal-poor stars is a matter of surprise because of the high values observed. Non-standard models of Big Bang nucleosynthesis and pre-Galactic cosmic ray fusion and spallation have been proposed to explain these values. However, the observations of this light isotope are challenging which may make some detections disputable.

6. Formation of giant globular cluster G1 and the origin of the M 31 stellar halo
- Author
-
Bekki, K., Chiba, M., Bekki, K., and Chiba, M.
- Abstract
We demonstrate that globular cluster G1 could have been formed by tidal interaction between M 31 and a nucleated dwarf galaxy (dE,N). Our fully self-consistent numerical simulations show that during tidal interaction between M 31 and G1's progenitor dE,N with $M_{B} \sim -15$mag and its nucleus mass of ~107$M_{\odot}$, the dark matter and the outer stellar envelope of the dE,N are nearly completely stripped whereas the nucleus can survive the tidal stripping because of its initially compact nature. The naked nucleus (i.e., G1) has orbital properties similar to those of its progenitor dE,N. The stripped stars form a metal-poor ([Fe/H] ~ -1) stellar halo around M 31 and its structure and kinematics depend strongly on the initial orbit of G1's progenitor dE,N. We suggest that the observed large projected distance of G1 from M 31 (~40 kpc) can give some strong constraints on the central density of the dark matter halo of dE,N. We discuss these results in the context of substructures of M 31's stellar halo recently revealed by Ferguson et al. ([CITE]).

7. The mass of the Milky Way: Limits from a newly assembled set of halo objects*
- Author

Sakamoto, T., Chiba, M., Beers, T. C., Sakamoto, T., Chiba, M., and Beers, T. C.
- Abstract
We set new limits on the mass of the Milky Way, making use of the latest kinematic information for Galactic satellites and halo objects. Our sample consists of 11 satellite galaxies, 137 globular clusters, and 413 field horizontal-branch (FHB) stars up to distances of 10 kpc from the Sun. Roughly half of the objects in this sample have measured proper motions, permitting the use of their full space motions in our analysis. In order to bind these sample objects to the Galaxy, their rest-frame velocities must be lower than their escape velocities at their estimated distances. This constraint enables us to show that the mass estimate of the Galaxy is largely affected by several high-velocity objects (Leo I, Pal 3, Draco, and a few FHB stars), notby a single object alone (such as Leo I), as has often been the case in past analyses. We also find that a gravitational potential that gives rise to a declining rotation curve is insufficient to bind many of our sample objects to the Galaxy; a possible lower limit on the mass of the Galaxy is about $2.2\times 10^{12}~M_\odot$. To be more quantitative, we adopt a Bayesian likelihood approach to reproduce the observed distribution of the current positions and motions of the sample, in a prescribed Galactic potential that yields a flat rotation curve. This method enables a search for the most likely total mass of the Galaxy, without undue influence in the final result arising from the presence or absence of Leo I, provided that both radial velocities and proper motions are used. Although the best mass estimate depends somewhat on the model assumptions, such as the unknown prior probabilities for the model parameters, the resultant systematic change in the mass estimate is confined to a relatively narrow range of a few times $10^{11}~M_\odot$, owing to our consideration of many FHB stars. The most likely total mass derived from this method is $2.5^{+0.5}_{-1.0}\times 10^{12}~M_{\odot}$(including Leo I), and $1.8^{+0.4}_{-0.7}\times 10^{12}~M_{\odot}$(excluding Leo I). The derived mass estimate of the Galaxy within the distance to the Large Magellanic Cloud (∼50 kpc) is essentially independent of the model parameters, yielding $5.5^{+0.0}_{-0.2}\times 10^{11}~M_{\odot}$(including Leo I) and $5.4^{+0.1}_{-0.4}\times 10^{11}~M_{\odot}$(excluding Leo I). Implications for the origin of halo microlensing events (e.g., the possibility of brown dwarfs as the origin of the microlensing events toward the LMC, may be excluded by our lower mass limit) and prospects for more accurate estimates of the total mass are also discussed.

8. Kinematic analysis of spiral structures in the local disk

Yano, T., Chiba, M., Gouda, N., Yano, T., Chiba, M., and Gouda, N.
- Abstract
We present a method, based on the kinematic analysis of the Galactic disk stars near the Sun, to clarify whether the internal motions of the stellar system in spiral arms follow those expected in the density wave theory. The method is based on the linear relation between the phases of spatial positions and those of epicyclic motions of stars, as predicted by the theory. The application of the method to the 78 Galactic Cepheids near the Sun, for which accurate proper motions are available from the HipparcosCatalogue, has revealed that these Cepheids show no correlation between both phases, mainly because of the large uncertainties in their spatial motions. This implies that previous studies for the calibration of the wave parameters using a similar sample to ours lack a clear physical basis: the currently available data of the Cepheids are still inaccurate to assess the presence of density waves in the solar neighborhood. We show the required accuracy for the astrometric data of the Cepheids to clarify the issue and future prospects are outlined.

- Abstract
The objectives of this study were to estimate the prevalence of anemia and iron deficiency among schoolchildren in the Aral Sea region of Kazakhstan and to determine the various factors associated with anemia in this population. We conducted a cross-sectional study of randomly selected schoolchildren. Blood samples were collected for measuring hemoglobin (Hb), serum ferritin (SF), total iron binding capacity (TIBC), and other hematological indices, and subjects were screened for anemia and iron deficiency. Associations between Hb concentration and SF, TIBC, anthropometric, and socioeconomic data were evaluated using regression analysis. The prevalence of anemia was 49.8 per cent although levels were mostly mild. Twenty-two per cent of the children were iron depleted (SF < 12 microg/l). Of the anemic children, 32.4 per cent were found to have iron deficiency anemia (anemia with SF < 12 microg/l). There were significant positive correlations between the levels of Hb and SF, but a negative correlation with serum TIBC. Age, mean corpuscular volume (MCV) and SF were found to be significantly related to Hb by stepwise multiple regression analysis. Multiple logistic regression analysis revealed that anemia was independently related to living district, education of father, and child's age. The results suggest that iron deficiency is an important determinant of anemia in this population; however, whole anemia cannot be solely explained by iron deficiency. Further studies are needed for consideration of micronutrients status, parasite infestation, hereditary disorders, and exposure to environmental pollutants.

12. VISCOUS HYDROELASTIC VIBRATIONS IN A CYLINDRICAL CONTAINER WITH AN ELASTIC BOTTOM
- Author

BAUER, H. F. and CHIBA, M.
- Abstract
The coupled motion of a viscous liquid in a cylindrical container with an elastic bottom is treated. The liquid exhibits a free surface with surface tension. The hydroelastic frequencies and decay magnitudes are determined for the lower angular- and radial modes, for which the influences of the various parameters are investigated. A new phenomenon was detected, showing that for low liquid height ratio an aperiodic range appears, in which the viscous liquid is not able to oscillate. This range decreases with growing membrane tension and increasing mode number. In addition, it was found that higher liquid modes experience larger damping and disappear from the motion as time goes on.

Chiba, M., Suzuki, S., Hinokio, Y., Hirai, M., Satoh, Y., Tashiro, A., Utsumi, A., Awata, T., Hongo, M., and Toyota, T.
- Abstract
A high association between type 2 diabetes mellitus and depressive illness has been reported. Insulin resistance during depressive illness might contribute to the linkage between depression and type 2 diabetes. To determine whether the genetic polymorphisms of the tyrosine hydroxylase ([TH] HUMTH01) and insulin (INS-VNTR) genes contribute to insulin resistance in depressive illness, we analyzed the association between the polymorphisms and insulin resistance in 41 Japanese patients with depressive disorder, 204 normal control subjects, 161 cohort subjects with normal glucose tolerance (NGT) and without depressive symptomatology, and 59 NGT subjects with depressive symptomatology. The depressive patients had a significantly lower insulin sensitivity index (SI) than the control subjects (P= .016). Depressive NGT subjects had a significantly higher homeostasis model assessment (HOMA) insulin resistance index [HOMA(R)] than the nondepressive NGT subjects (P< .0001). The depressive patients and NGT subjects had more HUMTH01 allele 7 (TH7) than the controls and nondepressive NGT subjects. SI was significantly lower in patients with the TH7/7 homozygote versus patients with the other genotypes and the controls. TH7 was associated with higher HOMA(R) as compared with the other alleles in the NGT subjects. Insulin resistance was associated with depressive disorders. The HUMTH01 and INS-VNTR were associated with insulin resistance and depressive symptoms.

20. HYDROELASTIC VISCOUS OSCILLATIONS IN A CIRCULAR CYLINDRICAL CONTAINER WITH AN ELASTIC COVER
- Author

BAUER, H.F. and CHIBA, M.
- Abstract
If the surface of a viscous liquid is completely covered by an elastic structure, the hydroelastic frequencies are shifted to a larger magnitude than those obtained with a free surface. It was found that viscosity decreases the oscillation frequencies in comparison to the coupled hydroelastic frequencies of frictionless liquid and that a new phenomenon appears, exhibiting for certain liquid height ranges h/aonly aperiodic motion. With increasing angular and radial mode numbers these aperiodic ranges of h/adecrease. Higher modes show larger damping. An increase in the membrane tension decreases the aperiodic region, while an increase in the mass of the membrane increases it.

- Abstract
Abstract: We report a case of a lumbar teratoma in a 50-year-old woman. The teratoma showed a dumb-bell-type expansion at the level of the left L3/4 foramen with massive erosion of the L3 vertebral body. MRI revealed inhomogeneous signal changes in the tumor, which were histologically compatible with a mixture of bone, muscle, fat, and cyst containing sebaceous material. Complete resection of the tumor and spinal arthrodesis with pedicle screw fixation was necessary to obtain stability of the affected spinal segment.

Hinokio, Y., Suzuki, S., Hirai, M., Chiba, M., Hirai, A., and Toyota, T.
- Abstract
Aims/hypothesis. Augmented oxidative stress induced by hyperglycaemia possibly contributes to the pathogenesis of diabetic complications. Oxidative stress is known to increase the conversion of deoxyguanosine to 8-oxo, 2 ′-deoxyguanosine in DNA. To investigate the possible contribution of oxidative DNA damage to the pathogenesis of diabetic complications, we measured the content of 8-oxo, 2 ′-deoxyguanosine in the urine and the blood mononuclear cells of Type II (non-insulin-dependent) diabetic patients. Methods. We studied 53 Type II diabetic patients and 39 age-matched healthy control subjects. We assayed 8-oxo, 2 ′-deoxyguanosine by HPLC-electrochemical detection method. Results. The content of 8-oxo, 2 ′-deoxyguanosine in the urine and the mononuclear cells of the Type II diabetic patients was much higher than that of the control subjects. Urinary 8-oxo, 2 ′-deoxyguanosine excretion and the 8-oxo, 2 ′-deoxyguanosine content in the mononuclear cells from the diabetic patients with complications were higher than those from the diabetic patients without complications. Urinary excretion of 8-oxo, 2 ′-deoxyguanosine was significantly correlated with the 8-oxo, 2 ′-deoxyguanosine content in the mononuclear cells. The 8-oxo, 2 ′-deoxyguanosine content in the urine and mononuclear cells was correlated with the haemoglobin A1 cvalue. Conclusion/interpretation. This is the first report of a direct association between oxidative DNA damage and the complications of diabetes. The augmented oxidative DNA damage in diabetes is speculated to contribute to the pathogenesis of diabetic complications. [Diabetologia (1999) 42: 995–998]Aims/hypothesis.

32. Recombinant vaccinia viruses expressing an immunodominant epitope of HIV-1 envelope protein within an influenza hemagglutinin cassette predominantly prime epitope-specific CD8+CTL

- Abstract
We constructed recombinant vaccinia viruses (RVV) expressing a 15-residue peptide (P18IIIB; RIQRGPGRAFVTIGK) of gp160 envelope protein from a human immunodeficiency virus type-1 (HIV-1) IIIB isolate using an H1 influenza virus hemagglutinin (HA) gene cassette. Immunofluorescent tests with antisera against both H1N1 influenza virus and P18IIIB localized chimeric HA molecules comprising influenza virus HA and P18IIIB peptide intracellularly, but the P18IIIB could not be seen on the outer surfaces of infected cells though weak fluorescence was detected regarding HA molecule. Consistent with these findings, Western blotting confirmed the expression of a polypeptide of about 74-kDa protein representing chimeric HA molecule in the infected cells. These recombinants markedly primed CD8+cytotoxic T lymphocytes (CTL) specific for P18IIIB as well as HA protein of the influenza virus, but failed to elicit P18IIIB-specific antibody despite stimulating production of HA-specific antibody. In addition, the P18IIIB-specific CTL could strongly lyse target cells expressing the whole HIV-1 envelope gene of IIIB strain. Thus, the influenza virus chimeric HA cassette vector system used in the present study appeared to be a useful tool for constructing vaccine candidates which will predominantly prime CD8+CTL specific for immunodominant determinants of various infectious agents.

35. Chlorophyll Fluorescence Applied in the Analysis on Vertical Movement of Herbicides in Soil

Yanase, D., Andoh, A., Chiba, M, and Yoshida, S.
- Abstract
Five photosynthesis inhibiting herbicides were compared for their mobility in soil columns used as the penetration model. The vertical movement of these compounds in soil was analyzed by a newly developed technique in which herbicide distribution was determ ined by the intensity of chlorophyll fluorescence in Chlorella cells suspended in aqueous extracts of soil samples from various depths. With the aid of a fluorescence microplate scanner, measurement of chlorophyll fluorescence was performed with great efficiency. Photosynthesis inhibiting activity of tested herbicides was determined beforehand by the same method and served in calculating herbicide concentrations in sample extracts. Among tested compounds, hexazinone showed the greatest mobility and diuron the smallest, suggesting water solubility is one of the factors which govern the soil mobility of herbicides.

- Abstract
This paper presents an analysis of the inclusive properties of diffractive deep inelastic scattering events produced inep interactions at HERA. The events are characterised by a rapidity gap between the outgoing proton system and the remaining hadronic system. Inclusive distributions are presented and compared with Monte Carlo models for diffractive processes. The data are consistent with models where the pomeron structure function has a hard and a soft contribution. The diffractive structure function is measured as a function ofx
P , the momentum fraction lost by the proton, of ß, the momentum fraction of the struck quark with respect toxP , and ofQ2 in the range 6.3·10-4 P <10 -2 , 0.1<ß<0.8 and 82<100 GeV
2 . The dependence is consistent with the formxP wherea=1.30±0.08(stat)-0.14 +0.08 (sys) in all bins of ß andQ2 . In the measuredQ2 range, the diffractive structure function approximately scales withQ2 at fixed ß. In an Ingelman-Schlein type model, where commonly used pomeron flux factor normalisations are assumed, it is found that the quarks within the pomeron do not saturate the momentum sum rule.- Published

- Abstract
Experimental studies of open charm production in two-photon processes have been performed. In the measurement, charmed hadrons were identified by electrons from their semi-leptonic decays. The result was compared with calculations based on the direct process and photon-gluon fusion process by resolved photons. We found that the effect of the gluon component in a photon is substantial in the observed events.

- Abstract
A search for excited states of the standard model fermions was performed using the ZEUS detector at the HERA electron-proton collider, operating at a centre of mass energy of 296 GeV. In a sample corresponding to an integrated luminosity of 0.55 pb
-1 , no evidence was found for any resonant state decaying into final states composed of a fermion and a gauge boson. Limits on the coupling strength times branching ratio of excited fermions are presented for masses between 50 GeV and 250 GeV, extending previous search regions significantly.- Published

41. Experimental Studies on a Nonlinear Hydroelastic Vibration of a Clamped Cylindrical Tank Partially Filled With Liquid

Chiba, M.
- Abstract
Experimental studies have been carried out on the nonlinear hydroelastic vibrations of a clamped circular cylindrical tank with a flexible wall and a rigid bottom. In the studies, two test cylinders, made of polyester, with radius R = 240 mm, thickness h = 0.254 mm, and length L = 480 and 160 mm (L/R = 2.0 and 2/3), respectively, were used. The tank is fully or partially filled with water having a free surface. The nonlinearity of the response of the flexible wall when the wall of the tank is harmonically excited by points was investigated, with varying liquid height. It was found that the degree of the nonlinearity depends on the vibration mode, i.e., a circumferential wave number and an axial wave number of the shell, on the length of the tank, as well as on the height of the liquid contained in it. The results obtained here were compared with the experimental results of a cantilevered tank, which was previously carried out. The influence of a thin film floating on the free surface upon the bulging-type responses, in which shell wall response is predominant, was also examined. On the free surface, sub-harmonic response with order 1/2 was observed when the amplitude of the shell wall became large.

42. Direct Measurement for Elasticity of Myosin Head

- Abstract
During muscle contraction, chemical energy from ATP hydrolysis is converted to the relative sliding movement of actin and myosin filaments. In order to elucidate the molecular mechanism of sliding-force generation, it is a crucial clue to know an elastic modulus of myosin. Here, we report direct measurements of Young′s modulus of myosin head (myosin subfragment-1) isolated from rabbit skeletal muscle, using a surface forces apparatus. Our results show that the elasticity of myosin subfragment-1 has direction and is about 0.3 GPa along the long axis during ATP hydrolysis. When the bow-shaped subfragment-1 is modelled as an elastic rod, the stiffness and the bending fluctuations of subfragment-1 are calculated to be 3 ∼ 7 pN/nm and about 1 nm, respectively. These results strongly support a model of multiple power strokes rather than the conventional tilting-crossbridge model.

Chiba, M., Shinohara, A., and Inaba, Y.
- Abstract
Determination of tin (Sn) concentrations in human blood samples was examined by atomic absorption spectrometry with a graphite furnace. The matrix modifiers, 120 μg/ml Ni, 0.1% H3PO4, and 10% ascorbic acid, in the furnace increased the sensitivity; the detection limit was 2.5 ng/ml when 10 μl of the sample solution was injected into furnace, namely 25 pg of Sn. When Sn in blood samples was determined, addition of ascorbic acid was necessary. The highest absorbance was observed when Ni, H3PO4, and ascorbic acid were added. Sn concentrations in blood of male smelter workers were very low, ranging from below the detection limit to 20 ng/ml, which were considered to be normal values.

- Abstract
Summary Serotype G6 human rotavirus PA151 was examined by RNA-RNA hybridization in comparison with another G6 strain PA169 and two naturally-occurring G3 reassortants PCP5 and MZ58. PA151 possessed three gene segments that formed hybrids with AU-1 and seven gene segments that formed hybrids with bovine rotavirus NCDV. PA151 also possessed eight, 10 and 10 gene segments that formed hybrids with genomic RNAs from PA169, PCP5, and MZ58, respectively. Thus, PA151 was an intergenogroup reassortant formed in nature between members of the bovine and AU-1 genogroups and it shared a genome constellation with PA169, PCP5, and MZ58. These results suggest that naturally-occurring intergenogroup reassortants possessing such a genome constellation were perpetuated in human populations.

- Abstract
The angular distributions of the reactione
+ e− →μ+ μ− ande+ e+ →τ+ τ− have been measured between and 60.8 GeV with the VENUS detector at TRISTAN. The average total cross section and the forward-backward charge asymmetry for μ-pair production are observed to be 28.3±1.4±0.8 pb and (−29.0−4.8 +5.0 ±0.5)%, and those for τ-pair production are 27.6±1.7±1.0 pb and (−32.8−6.2 +6.4 ±1.5)% at . These values are consistent with the predictions of the standard model of electroweak interactions.- Published

- Abstract
This paper presents energy distributions of the hadronic system produced in neutral-current electron-proton deep-inelastic scattering at a centre of mass energy of 296 GeV. Comparison of the results with QCD Monte Carlo models shows that QCD radiation has a strong influence on the characteristics of the final state. The data are reasonably reproduced by the Lund model based on a matrix element calculation in first order ofa
s , followed by appropriate parton showers, as well as by the colour dipole model. The HERWIG parton shower model also gives a reasonable representation of the data. Neither the first order matrix elements alone nor the Lund parton shower model, without the matrix element calculation, reproduce the data.- Published

- Abstract
We report Mn superoxide dismutase (SOD) protein and activity in a patient with familial autosomal recessive Lewy body-negative parkinsonism in comparison with patients with sporadic Parkinson's disease (PD) and controls. We recently proved linkage of this family with markers of chromosome 6 at 6q25.2-27, which included the Mn SOD gene. We used a novel polymorphic mutation at -9 position of the signal peptide of the Mn SOD precursor protein, which caused valine to alanine substitution. All the affected members of this family showed homozygosity for alanine, whereas nonaffected members, sporadic PD patients, and the control subjects studied showed either heterozygosity of alanine and valine or homozygosity of valine. The Mn SOD activity of this familial patient was the highest among the PD patients and the control subjects studied, and an abundant expression of Mn SOD was found in the substantia nigra. The molecular weight of Mn SOD protein by Western blotting of this patient was essentially similar to that of PD patients and the control subjects. High Mn SOD activity may constitute a genetic risk factor in this familial patient. The difference in the signal peptide sequence may affect the expression of Mn SOD within mitochondria; however, it is unlikely that loss of function type Mn SOD mutation is the cause of this familial parkinsonism. Mn SOD in sporadic PD patients was similar to that in controls.
