    Notes: [Auszug] The critical importance of dosage compensation is underscored by a novel human syndrome (“XYXq syndrome”) in which we have detected partial X disomy, demonstrated supernormal gene expression resulting from the absence of X inactivation, and correlated this overexpression with its ...

    Notes: Summary The Miller-Dieker Syndrome (MDS) consists of lissencephaly, characteristic facies, pre- and postnatal growth retardation, plus various other birth defects. Autosomal recessive inheritance has been presumed based on four reported families with two or more affected siblings. We present substantial evidence that monosomy 17p13.3 causes the MDS phenotype. This includes two patients with ring chromosome 17, one patient with a de novo 17p13 deletion, and one patient with monosomy 17p due to an unbalanced 7p; 17p translocation. We report the first prenatal diagnosis of MDS in a 20-week fetus from this latter family. Additionally, we report a balanced translocation between chromosome 17 and different autosomes (8, 12, and 15) in three of the four familial cases of lissencephaly. The finding of a chromosomal basis for this presumed autosomal recessive disorder significantly alters genetic counseling and makes prenatal diagnosis possible in some families.

    Description / Table of Contents: Zusammenfassung Die Interpretation der Abhängigkeit von Relaxationszeiten und Viskositäten von der Temperatur auf Grund des freien Volumens läßt sich in bezug auf Konzentrations-, Druck- und Zugkraftbereich erweitern. Der Koeffizient, der in derWilliams/Landel/Ferry -Gleichung die thermische Expansion des relativen freien Volumens repräsentiert, hat die folgenden bezüglichen Analoga: Für die Konzentrationsabhängigkeit eine Konstante, die eng mit dem fraktionellen freien Volumen der Verdünnungsflüssigkeit verkoppelt ist; für die Druckabhängigkeit den Anteil an Kompressibilität, der dem Verschwinden an freiem Volumen zugeschrieben werden muß; für die Zugkraft eine Konstante proportional zu 1–2μ, wobeiμ dasPoissonsche Verhältnis ist. Die Behandlung ist wahrscheinlich auf Bedingungen begrenzt, in denen das freie Volumen nicht größer als 0.08 wird. Im Fall der Druckabhängigkeit findet sich, daß einige Viskositätsdaten an Kohlenwasserstoff- und Silikonflüssigkeiten bei hohen Drucken sehr gut mit der vorausgesagten Form und mit vernünftigen Werten der assoziierten Parameter übereinstimmen.
    Notes: Summary The free volume interpretation of the dependence of relaxation times and viscosities on temperature can be extended to their dependence on concentration, pressure, and tensile strain. The coefficient which in theWilliams/Landel/Ferry equation represents the thermal expansion of the relative free volume has the following analogs, respectively: for concentration dependence, a constant closely related to the fractional free volume of the diluent liquid; for pressure dependence, the part of the compressibility attributable to collapse of free volume; for tensile strain, a constant proportional to 1–2μ, whereμ isPoisson's ratio. The treatment is probably limited to conditions where the fractional free volume is not greater than 0.08. In the case of pressure dependence, some viscosity data on hydrocarbon and silicone liquids at high pressures are found to agree closely with the predicted form with reasonable values of the associated parameters.

    Notes: The viscoelastic properties of a 4% solution of monodisperse polystyrene (molecular weight 394,000) in Aroclor 1260 were determined by the following techniques: creep recovery, stress relaxation upon cessation of steady flow, dynamic measurements, and normal stress difference and shear stress measurements in steady flow. All measurements were carried out with cone and plate geometry in a Weissenberg rheogoniometer. The modification of this instrument to perform creep and creep recovery experiments by use of an air-bearing suspension and an air-turbine drive is described. A broad range of shear rates and frequencies encompassing both linear and nonlinear behavior was employed. The elastic behavior is described in terms of the recoverable shear strain s or the steady-state compliance Je°. The first three techniques gave identical results for Je° in the range of linear viscoelasticity for which it is defined. The normal stress difference measurements confirmed Lodge's relation s = (P11 - P22)/2σ21. Reasons for previous experimental disagreement with this result are discussed.

    Notes: The basis for obtaining the steady-state compliance from stress relaxation upon cessation of steady flow (SRUCSF) data is derived. Measurements on three polymer solutions of differing molecular weight, polydispersity, and degree of entanglement coupling show good agreement between results from SRUCSF and creep-recovery experiments in both linear and nonlinear viscoelastic regions. The stress overshoot phenomenon is interpreted in terms of a change in entanglement spacing upon imposition of a shearing field. The phenomenon is analyzed in terms of a relaxation time for re-entanglement, which is found to be much longer than the relaxation time of the shear stress upon cessation of steady flow.

    Notes: The dynamic mechanical properties at about 1 Hz of a film of regenerated cellulose have been measured over a range of temperatures from -100 to +90°C and water contents from effectively zero to 3%. Three loss peaks were found which were attributed to molecular motions in the amorphous regions. One of these was postulated to involve motion of segments of two chains connected through hydrogen bonding via a “tightly bound” molecule of water. Viscoelastic measurements over a somewhat wider range of water contents at room temperature exhibited contradictory effects depending upon the amount of water. These results provide support for the concept of two types of water in cellulose: tightly bound and loosely bound.
