    Characterization of Na+ exclusion mechanisms of salt-tolerant reed plants in comparison with salt-sensitive rice plants (1991)

    Topics: Biology
    Notes: Salt-tolerant reed plants (Phragmites communis Trinius) and salt-sensitive rice plants (Oryza sativa L. cv. Kinmaze) were grown in salinized nutrient solutions up to 50 mM NaCl, and growth, Na+ contents and kinetics of 22Na+ uptake and translocation were compared between the species to characterize the salt tolerance mechanisms operating in reed plants. When both plants were grown under the same salinity, Na+ contents of the shoots were lower in reed plants, although those of the roots were quite similar. The shoot base region of both species accumulated Na+ more than the leaf blades did. Sodium-22 uptake and pulse-chase experiments suggested that the lower Na+ transport rate from root to shoot could limit excessive Na+ accumulation in the reed shoot. There was a possibility that the apparently lower 22Na+ transport rate to the shoot of reed plants was due to net downward Na+ transport from shoot base to root.

    Notes: Dual-in-line packages (DIPs) were formed from epoxy molding compounds with various physical properties using a transfer molding machine. The compounds were prepared by changing kinds and amounts of additives and addition methods. The thermal shock test was carried out by the following procedures. The plastic package was soaked alternately in liquid nitrogen (-196°C) and in liquid solder (250°C) in the cycle of 140 s. The packages were intermittently subjected to optical microscopic inspection for crack initiation. The median life to crack initiation is defined to be the number of the cycles when half of the specimens exhibited crack initiation. Glass transition temperature, coefficient of linear expansion, and flexural modulus were measured to calculate thermal stress in plastic packages. According to the linear fracture mechanics, the following expression was obtained among the median life N, thermal stress σt and strength σb. N =/σ b2 We found the linear relation between logarithm of Nσ b2 and logarithm of σb/σ t for various packages, and obtained that the value of C and m are estimated as 3 × 104 MPa2 and 5.5, respectively. Therefore, the median life can be predicted from the glass transition temperature, coefficient of linear expansion, flexural modulus, and strength of plastic materials for packages.

    Anomalous behavior of electrical conductivity of solubilized collagen solutions with thermal denaturation (1993)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: The temperature dependence of the electrical conductivity, σ, for a collagen solution was measured in the temperature region including the thermal denaturation temperature, td. The σ increased with temperature, t, but decreased at ca. 40°C, and then again increased. In this temperature region, a change of optical rotation, αD, was observed. The change is due to the thermal denaturation. The differential curve of σ vs. t gave clear deflection points and a large peak at ca. 40°C. The td could be estimated from the peak temperature. The td decreased with the increase in the concentration of collagen and with the decrease in the heating rate. These measurements were carried out for the collagen prepared by various methods. Some of them showed one peak; others had two peaks. The td obtained by the measurement of σ correlated with that obtained by the measurement of αD. The activation energy of σ, ΔEa, obtained from the linear relationship between log σ and 1/T, increased with the concentration of collagen, but was unchanged for the heating rate. The ΔEa obtained for various types of collagen showed a constant value. © 1993 John Wiley & Sons, Inc.

    Temperature dependence of pH for solubilized collagen solutions (1994)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: The temperature dependence of the pH for an acid-soluble collagen in solution was measured, so that the pH largely increased in the temperature region including ca. 40°C of the thermal denaturation temperature. As the changes of the optical rotation, αD, and the electrical conductivity, σ, were observed in this temperature region, the change of the pH is due to the thermal denaturation of collagen. The differential curve of pH vs. t gave clear deflection points and a large peak at ca. 40°C. The thermal denaturation temperature, td, could be estimated from the peak temperature. The td obtained by the measurement of the αD, tdαD, decreased with the decrease in the heating rate and with the increase in the concentration of collagen. However, the td obtained through the measurement of the pH, tdpH, was independent of the variations of the heating rate and the concentration of collagen. These measurements were carried out for different kinds of collagens prepared by various methods. Some of them had one kind of peak; others had two kinds of peaks. The tdpH correlated with the tdαD for different kinds of collagen preparations. Therefore, the measurement of the temperature dependence of the pH was useful for the determination of the td. © 1994 John Wiley & Sons, Inc.

    Notes: Flat packages (FPs) were formed from epoxy molding compounds with various physical properties using a transfer molding machine. The compounds were prepared by changing kinds and amounts of additives and addition methods. The thermal shock test was carried out by the following procedures. The plastic package was soaked alternately in liquid nitrogen (-196°) and in liquid solder (200°) in the cycle of 140s. The median life to crack initiation was defined to be the cycles when half of the specimens exhibited crack initiation. According to linear fracture mechanics, the following expression was obtained relating the median life N, thermal stress σt, and strength σb; N = C/σb2·(σb/σt)m. We found the linear relation between logarithm of Nσb2 and logarithm of σb/σt for various packages, and estimated the values of C and m as 5 × 104 MPa2 and 5.5, respectively. The value of m was the same as that obtained for a dual-in-line package.

    Two-film effects on the kinetics of hydrogen isotope exchange between CHCl3 and D2O in two liquid phase system (1993)

    Notes: A model based on the two film approximation is proposed for the description of the kinetics of the hydrogen isotope exchange between CHCl3 and D2O. In this model, details of mass transfer in interfacial region between the two liquid phases are considered and the kinetics of the exchange reaction is quantitatively described without an adjusting parameter. This model is successful in explaining the experimental results obtained with high alkali concentrations, which has not been sufficiently explained in our previous article [M. Iwasaki et al., J. Phys. Chem., 93, 5139 (1989)]. © 1993 John Wiley & Sons, Inc.

    Detection of thymopoietin-responsive proteins in nude mouse spleen cells by two-dimensional polyacrylamide gel electrophoresis and image processing (1994)

    Notes: Lymphoid cells isolated from the spleen of BALB/c nu/nu nude mice were treated with synthetic human thymopoietin, and newly synthesized proteins were labeled by [35S]methionine incorporation. In the control experiment, the same lot of spleen cells were incubated in the labeling medium without the addition of thymopoietin. Urea/detergent-soluble proteins were extracted from the cells after 3 h incubation to be separated by two-dimensional polyacrylamide gel electrophoresis. Spots of [35S]methionine-labeled proteins were visualized by autoradiography and analyzed by image processing. The computer-aided spot matching screened out three major thymopoietin-responsive proteins, TRP-1, -2 and -3. [35S]Methionine incorporation into TRP-3, of which the isoelectric point and molecular mass were approximately pI5 and 10 kDa, respectively, was decreased by the thymopoietin treatment. In contrast with the down regulation, TRP-1, which was slightly higher in pI and slightly larger in molecular mass, and TRP-2, which was slightly higher in pI and almost the same in molecular mass as TRP-3, were evidently induced by the treatment. However, TRPs could not be assigned to Thy-1 antigen on the difference in molecular mass. The specific induction by the thymopoietin treatment suggested that TRP-1 and -2 might be novel proteins related to the intracellular signal transduction.
