    Notes: 2D NMR spectra have been measured at variable temperatures between -100°C and +110°C in a sample of melt crystallized deuterated polyethylene (PE). The line shape could be decomposed into a central part originating from deuterons in the amorphous regions and outer parts from crystalline regions of PE. The “NMR crystallinity” determined from this separation was 72% in agreement with the X-ray crystallinity of 74%. Changes of the crystalline NMR line shape were interperted in terms of oscillations around the chain axis, the r.m.s. oscillation amplitude varying from 5° at 40°C to 12° at 110°C. The central part of the NMR line shape indicates the existence of a “narrow” and a “medium” component due to different motional processes in the amorphous regions.

    Description / Table of Contents: Zusammenfassung Es wird von einer Familie berichtet, in der durch mütterliche balancierte Translokation t(5;10)(p15;p13) eine unbalancierte Chromosomenkonstitution bei zwei Kindern entstand. Mit Hilfe der G-Bandenanalyse wurde sie als Trisomie des distalen Abschnitts des kurzen Armes von Chromosom 10 (p13→pter) identifiziert. Der Vergleich mit 15 Literaturberichten von Trisomie 10p bestätigt das Vorliegen eines charakteristischen Dysmorphiesyndroms.
    Notes: Abstract This is the report of a family in which a balanced translocation in the mother t(5;10)(p15;p13) led to an unbalanced chromosomal constitution in two children. It was identified by G-banding analysis as trisomy of the distal portion of the short arm of chromosome 10 (p13→pter). Comparison with 15 previous reports of trisomy 10p confirms the existence of a characteristic dysmorphic syndrome.
