    The effect of deuterium oxide on protein turnover in Lemna minor (1979)
    Springer
    Planta 146 (1979), S. 229-236 
    Details
    ISSN: 1432-2048
    Keywords: Density labelling ; Deuterium oxide ; Lemna ; Protein turnover
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Lemna minor fronds transferred to a sterile culture medium containing 50% (v/v) deuterium oxide (2H2O) rapidly undergo a loss of soluble protein with a corresponding increase in free amino acids. The loss of protein is due to two factors: (i) the inhibition of protein synthesis for 4 h followed by a slower rate of synthesis than normal, (ii) a rapid 9–10 fold increase in protein degradation. In plants grown for longer periods (3–6 days) in 50% 2H2O medium, protein synthesis is inhibited by 20% and the rate constant of degradation is 2–3 times that measured in fronds growing in normal (H2O containing) complete medium. The initial loss of protein is not due to the breakdown of any specific protein fraction. Investigation of several enzymes indicates that all proteins are catabolised in response to 2H2O treatment. The implications of these results with regard to the interpretation of density-labelling experiments are discussed.

    The mechanism of deuterium oxide-induced protein degradation in Lemna minor (1980)
    Springer
    Planta 148 (1980), S. 374-380 
    Details
    ISSN: 1432-2048
    Keywords: Deuterium oxide ; Lemna ; Protein degradation ; Stress (D2O) ; Tonoplast properties
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Transfer of Lemna minor fronds to culture medium containing 50% (v/v) deuterium oxide induces a large increase in the rate of protein breakdown, which is not due to an increase in the activity of acidic or neutral proteolytic enzymes or peptidases. Biochemical and ultrastructural evidence indicates that deuterium oxide affects the properties of certain membranes, particularly the tonoplast, and allows vacuolar proteolytic enzymes to pass into the cytoplasm and cause the increased protein breakdown.

    Topics: Biology
    Notes: Abstract The lateral cotyledonary meristems of germinating Pisum sativum cv. Puget seeds were used to develop a reproducible Agrobacterium tumefaciens-mediated trans-formation system. This procedure exhibits distinct advantages over those previously reported, in that it uses dry seed as starting material, and the highly regenerable cotyledonary meristems rapidly produce transgenic shoots without an intermediate callus phase. This transformation regime facilitates the rapid generation of phenotypically normal, self-fertile plants containing functional transgenes inherited in a Mendelian fashion.

    Notes: The thermodynamical parameters (free energy, enthalpy, and entropy) of complex formation between ethidium bromide and single-stranded and double-stranded tetranucleotides of different base sequence [5′-d(TpGpCpA), 5′-d(ApCpGpT), and 5′-d(ApGpCpT) have been determined from the temperature dependencies of 500 MHz proton nmr chemical shifts. The analysis enables the contributions to be differentiated for the formation of different types of complexes (1:1, 2:1, 1:2, and 2:2) in aqueous solution. The results have been interpreted in terms of the main types of intermolecular interactions responsible for formation of the different complexes; van der Waals and electrostatic interactions are important for formation of complexes of ethidium bromide with single-stranded tetranucleotides, whereas van der Waals and hydrophobic interactions play a significant role in the binding of the dye to the tetramer duplexes. © 1997 John Wiley & Sons, Inc.

    Nitrogen-phosphorous antagonism in flame-retardant cotton (1986)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Applied Polymer Science 31 (1986), S. 1655-1662

    Notes: Phosphorous, as sodium dihydrogen phosphate, and nitrogen, in the form of a urea-for-maldehyde condensate, were applied to cotton fabric. The flame-retarding character of each treated fabric was assessed by determining the respective limiting oxygen index. Analysis of the results showed that at the lowest levels of applied phosphorous (P = 2%), the presence of nitrogen produced less than an additive combined flame-retarding effect. At higher phosphorous levels, this deviation from additivity increased until at P 〉 6%, the presence of nitrogen antagonized the flame-retarding effect of the phosphorous. These observations are discussed within the current ideas of nitrogen-phosphorous interaction in flame-retardant systems, for cotton-containing fabrics.

    The electroinitiated polymerization of N-vinylcarbazole with zinc bromide, IIPart I: cf.12.. Kinetics of polymerization (1973)

    Description / Table of Contents: Die elektroinitiierte Polymerisation von N-Vinylcarbazol (VCZ) wurde in Aceton bei 25°C mit Zinkbromid als Katalysator unter Verwendung von Platinelektroden eingehend untersucht. Die Polymerisationsgeschwindigkeit erwies sich als direkt abhängig von der Stromstärke, der Zinkbromid-Konzentration und dem anfänglichen Wassergehalt des Solvens.Die Molekulargewichte der entstandenen Polymeren (1000-6000) sind unabhängig von der Stromstärke, der Zinkbromid-Konzentration und dem Umsetzungsgrad des Monomeren zum Polymeren, werden jedoch beeinflußt durch Wasser, die Monomerkonzentration und das Elektrodenmaterial. Die chemische Zusammensetzung der Polymeren ändert sich nicht mit der Stromstärke, der Zinkbromid-Konzentration, dem Umsetzungsgrad und dem Elektrodenmaterial. Sie ändert sich jedoch ein wenig mit dem Wassergehalt des Acetons.
    Notes: The electroinitiated polymerization of N-vinylcarbazole (VCZ) in acetone solvent at 25°C with zinc bromide, as catalyst, and platinum electrodes was investigated in detail. The polymerization rate was found to be directly dependent on current strength, zinc bromide concentration and the initial water content of the solvent.The molecular weights of the formed polymers (1000-6000) are independent of current strength, zinc bromide concentration and degree of conversion of monomer to polymer, but are affected by water, monomer concentration, and by the type of electrodes used. The chemical composition of the polymer is invariant with current strength, zinc bromide concentration, degree of conversion, and electrode material but does vary slightly with the water content of acetone.
