NMR microscopy of polyacrylamide hydrogel.

Polyacrylamide Hydrogel (PAMG) is a kind of water-absorbing functional material. It has the ability of absorbing large amounts of water and releasing water under different conditions. So PAMG has an extensive background of applications in many fields. It is an interesting problem to clarify the distribution and status of water in PAMG1. This paper reports experiments in which the proton distribution and structures of networks in gamma-irradiation crosslinked PAMG samples have been shown by using spin-echo single-slice imaging of nuclear magnetic resonance microscopy.

Zygosity in two cases of triplet.

A total of 11 techniques including 57 items for zygosity diagnosis was employed in two sets of triplet. Namely, placenta-fetal membrane, LDH isoenzymes, etc. The authors made an investigation in detail on the pedigree history of polyembryony and systematic analysis of two sets of male triplets. The conclusion was that the first triplet came from a single ovum, whereas the second triplet developed from double ova. Different methods for the zygosity diagnosis were discussed. It was considered that there was hereditary influence in the occurrence of triplets developing either from a single ovum or from multiple ova.
