    Mechanisms of the contractile effects of flosequinoxan (1995)

    ISSN: 1432-1912
    Keywords: Key words Flosequinoxan ; Positive inotropic effect ; Phosphorylation ; Phosphatase ; Phospholamban ; Inhibitory subunit of troponin

    Notes: Abstract  In guinea-pig papillary muscles the positive inotropic effect of flosequinoxan (BTS) starting at 100 μmol/l amounted to 287.6±34.2% at 300 μmol/l without any effects on time to peak tension (103.9±2%) and relaxation time (107.1±6.7% of predrug value, respectively). 10 μmol/l carbachol attenuated the positive inotropic effect of 300 μmol/l to 166.5±11.6% (n=10). The phosphorylation state of the inhibitory subunit of troponin (TnI) and phospholamban (PLB) in [32P]-labeled guinea-pig ventricular myocytes was increased starting at 100 μmol/l amounting to 142.5±12.6% and 130.9±2.2% at 300 μmol/l, respectively (n=5). Furthermore, BTS (300 μmol/l) decreased phosphorylase phosphatase activity by 23.1%. It is concluded that the contractile effects of BTS are accompanied by enhanced phosphorylation of regulatory proteins which could in part be due to inhibition of phosphorylase phosphatase activity.

    Structural and property correlations of ethylen-α-olefin copolymers (1989)
    Springer
    Colloid & polymer science 267 (1989), S. 480-493 
    Details
    ISSN: 1435-1536
    Keywords: Polyethylene ; sidechainbranching ; fractionation ; x-ray ; DSC ; NMRinvestigations ; structure-propertycorrelations
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract Ethyleneα-olefin copolymers differ from other polyethylenes in that: - there is no long chain branching; - short chain branching is determined by the comonomer unit; - the molecular mass distribution is sharp; - the side chain distribution on different molecules is broad; - the sequential distribution of branching is very broad along the molecular chains, which becauses a multi-peak lamella distribution, and a multi-peak melting heat. With the help of a cross-fractionation method we interpreted the differences of the experimental data, according to the molecular mass fractionation and the branching received. The thermal history has a great influence on ethylene-α-olefin copolymers, evidenced in the crystallization time for the same branching type, but with extremely varied branching percentages.

    Chain-structure-superstructure relations in eutectoid copolymers (1989)

    ISSN: 1435-1536

    Notes: Abstract It will be shown that low-density polyethylene is a eutectoid copolymer with non-random distribution of branchings along the chains. From a line-profile analysis it is deduced that the crystal-size-distribution is uniquely related with the distribution of branchings thus yielding that basic features of the colloid-structure are controlled by the chemical structure of the macromolecules.

    Determination of crystallite particle size distribution of polymers from WAXS (1996)
    Bognor Regis [u.a.] : Wiley-Blackwell
    Journal of Polymer Science Part B: Polymer Physics 34 (1996), S. 485-496 
    Details
    ISSN: 0887-6266
    Keywords: X-ray line profile analysis ; crystallite size distribution ; (ethylene 1-hexen)-copolymers ; recrystallization in LPE ; Chemistry ; Polymer and Materials Science
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology , Physics
    Notes: A method for the calculation of crystallite size distributions from the profile of wide-angle x-ray reflections is developed. The influence of lattice distortions on the profile is taken into account. The information about the lattice distortions is obtained from the measurement of the integral widths of a number of reflections. The method is applied to samples of (ethylen-1 hexen) copolymers. The change of crystallite size distributions in lateral directions with increasing temperature (20-121°C) is measured. Recrystallization processes at temperatures near the melting point are observed. © 1996 John Wiley & Sons, Inc.

    Zur Charakterisierung der mechanischen Eigenschaften von Polymeren (1984)

    Description / Table of Contents: Based on experimental results a strain region is proved to exist in chemical multifilament yarns (about 0 to 0.3%) in which the linear theory of viscoelasticity holds as in polymer solids, the deviations caused by the multifilamentary composition having to be taken into account. The moduli determined by different methods can be described by a common pattern with respect to the value and time of the stress applied. With highly oriented samples the maximum of the modulus indicates the begin of irreversible deformation and depends on the length distribution of the molecules.
    Notes: An Hand experimenteller Resultate wird der Nachweis erbracht, daß auch für Chemieseiden ein Dehnungsbereich existiert (ca. 0 bis 0,3%), für den genau wie bei kompakten Polymerfestkörpern die lineare Viskoelastizitätstheorie gilt. Bei diesem Material sind jedoch die auf Grund des polyfilen Charakters entstehenden Meßfehler zu berücksichtigen. Die mit unterschiedlichen mechanischen Untersuchungsmethoden ermittelten Moduli lassen sich unter Beachtung der Beanspruchungshöhe und -zeit in ein gemeinsames Bild einordnen. Das Maximum im Modulverlauf zeigt bei hochorientierten Proben den Beginn der irreversiblen Verformung an und ist abhängig von der Längenverteilung der Verbindungsmoleküle.
