    Notes: Summary It was found that some ciliates,Stentor, Spirostomum andBlepharisma, which can contract rapidly like the stalks of Vorticellidae, have Ca2+-binding proteins that are very similar to spasmins, in the immunological sense. The presence of spasmins in other Protozoa and in some Metazoa was also investigated.

    Effect of oridonin, aRabdosia diterpenoid, on radiosensitization with misonidazole (1987)
    Springer
    Cellular and molecular life sciences 43 (1987), S. 1221-1223 
    Details
    ISSN: 1420-9071
    Keywords: Oridonin ; Rabdosia diterpenoid ; thiol-reactive agent ; misonidazole ; radiosensitizer

    Topics: Biology , Medicine
    Notes: Summary The radiosensitization brought about by oridonin, one of theRabdosia diterpenoids, alone or in combination with misonidazole, was investigated in Chinese hamster V79 cells. The enhancement ratio of 1.92 was obtained when 0.01 mM oridonin and 1 mM misonidazole were administered to hypoxic cells under radiation. The enhancement ratios of oridonin and misonidazole for hypoxic cells were 1.16 and 1.59 respectively. Hence, a supra-additive effect was obtained by the combined treatment with these two drugs. Under aerobic conditions, no effect of 0.01 mM oridonin on the radiosensitization caused by misonidazole was observed.

    Disposition of β-hexachlorocyclohexane, p,p′-DDT, and trans-chlordane administered subcutaneously to monkeys (Macaca fascicularis) (1992)

    Notes: Abstract To evaluate skin lipid analysis for the accumulation level of environmental pollutants, the correlations between organochlorine pesticide residues in adipose tissue, blood, and skin lipids of monkeys were studied. The mixture of β-hexachlorocyclohexane (β-HCH), p,p′-DDT, and trans-chlordane was subcutaneously given to monkeys once weekly for 5 weeks at dose levels of 1 and 10 mg/kg. The chemicals distributed in adipose tissue, blood, and skin lipids were determined six times after the last dosing at intervals of 4 to 9 weeks. Oxychlordane and p,p′-DDE were detected in all tissues together with the administered chemicals. In blood and adipose tissue, trans-chlordane decreased rapidly and oxychlordane and p,p′-DDE increased gradually and then remained at constant levels. β-HCH and p,p′-DDT in adipose tissue increased until the 12th week and then decreased in all animals. The correlation coefficients between blood and adipose tissue regardless of dose level and collection time for each chemical ranged from 0.83 to 0.94. Correlation coefficients between skin lipids and adipose tissue varied with the chemical, namely, 0.31, 0.72, 0.81, 0.81, and 0.83 for p,p′-DDE, tras-chlordane, p,p′-DDT, β-HCH, and oxychlordane, respectively. The results indicated that skin lipid analysis may be useful for the evaluation of specific pollutants in the body burden.

    Dynamic sweating response of man to infrared irradiation in various spectral regions (1991)
    Springer
    International journal of biometeorology 35 (1991), S. 18-23 
    Details
    ISSN: 1432-1254
    Keywords: Sweating ; Infrared irradiation ; Spectral region ; Cutaneous thermoreceptor ; Skin temperature
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geography , Physics
    Notes: Abstract In an attempt to detect differences in the thermal effect of infrared irradiation of different wavelengths, transient sweating response to infrared irradiation in various spectral regions was examined. In Series 1, the ventral or dorsal surface of the nude subject was irradiated repetitively for a period of 4 min (2 min on, 2 min off) by each of three kinds of infrared heaters with main emissivity in ‘near-infrared’ (NIR; 0.7–2.8 μm), ‘intermediate-infrared’ (MIR; 1.5–5.8 μm), and ‘far-infrared’ (FIR; 2.8–25 μm) regions. The sweating response on a non-irradiated area tended to be the greatest with MIR, while the magnitude of the sweating response on the irradiated area showed no consistent differences among various wavelengths. The results infer that MIR stimulated cutaneous thomoreceptors most effectively, while its direct effect on local sweat gland activity was minimal. In Series 2, the effects of 9–12 min irradiations in more restricted ranges of wavelength were compared by the combination of the three kinds of heaters with filters (translucent to wavelength ranges of 1.3–2.7, 2.7–3.5, 3.6–8.0 μm, respectively). The sweating response on a remote area was predominantly greater with the range of 2.7–3.5 μm than with the other wavelength ranges, while the local effect on sweating was minimal with this range. The results of Series 2 reinforce those of Series 1, indicating that the degree of stimulation of cutaneous thermoreceptors and of direct thermal effect on sweat gland activity differ with spectral regions incident on the skin, thus affecting local and remote effects on the sweating response.

    Notes: Summary Polymerization conditions of dl-phenylalanine N-carboxyanhydride (NCA) by m, p-vinylbenzylamine were examined for the preparation of (vinylbenzylimino)oligo(dl-phenylanaline NCA) macromer (VB-OPhe) with narrow molecular weight distribution. According to the results obtained, i.e., under the condition of short polymerization time (ca. 2 h) and in relatively high concentrations of the NCA in THF, the polymerizations of the NCA were carried out to give VB-OPhe macromers, which were found to have very narrow molecular weight distributions. Furthermore, their functionalities were proved to be approximately unity by the polymerization method.

    Dielectric relaxation of polyorganophosphazenes (1992)
    Springer
    Journal of inorganic and organometallic polymers and materials 2 (1992), S. 255-267 
    Details
    ISSN: 1572-8870
    Keywords: Polyorganophosphazene ; dielectric relaxation ; two-site model ; conformation analysis
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Dielectric relaxation spectra of poly(bis-trifluoroethoxy phosphazene) (PBFP), poly(bis-n-propoxy phosphazene) (PBPP), and poly(bis-n-propylamino phosphazene) (PBPAP) were measured in wide temperature and frequency regions, and the α-relaxation caused by micro-Brownian motion of segments in the rubbery state and the β-relaxation due to the local motions of the polymer in the glassy region were observed. The dielectric spectra of PBFP at temperatures higher than the rubbery region exhibited a mesophase transition at 358 K. From conformation analysis according to the two-site model, it has been elucidated that the mechanism for β-relaxation of these samples is hindered internal rotation of the side groups.

    Static and dynamic properties of XY systems with extended defects in cubic anisotropic crystallines (1985)
    Springer
    Journal of statistical physics 41 (1985), S. 497-530 
    Details
    ISSN: 1572-9613
    Keywords: Phase transitions and critical phenomena ; efects ; random systems
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Static and dynamic critical behavior ofXY systems in cubic anisotropic crystallines, with extended defects (or quenched nonmagnetic impurities) strongly correlated alongɛ d -dimensional space and randomly distributed ind − ɛ d dimensions, were studied. These extended defects make the systems coordinate anisotropic, resulting in unique critical behavior due to competition between the cubic anisotropy and the coordinate anisotropy. The systems were analyzed by anɛ 1/2 (ɛ≡4 − d) type of expansion with double expansion parameters based on a renormalization-group (RG) approach. Critical exponents were calculated near the second-order phase transition point and the behavior of the first-order transition was evaluated near the tricritical point.

    Quark-gluon plasma formation in the central rapidity region and finite size effects of colliding nuclei (1984)
    Springer
    The European physical journal 23 (1984), S. 391-403 
    Details
    ISSN: 1434-6052
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The energy density of the central products in the ultra-relativistic heavy ion collisions are calculated. In our estimation, the special attention is paid to the space-time extension of the emission points of the secondary hadrons which are originate in the successive nucleon-nucleon interactions within the finite size of colliding nuclei. The average collision number per produced particle, in the final state interaction, is also calculated and is used as a criterion whether the system is thermalized or not. It turns out that the attainable energy density in the central heavy ion collision is sensitive to the spacetime extension of the emission points. However, if the incident energy and the mass numbers of colliding nuclei are high and large, we can get high enough energy density for the phase transition from a hadronic state to a quark-gluon plasma state.
