“…The potential of preselecting of euploid embryos for transfer is in agreement with the fact that more than half of oocytes and embryos tested in PGD for poor prognosis IVF patients were shown to be with chromosomal abnormalities [Gianaroli et al, 2001; Munne, 2002; Kuliev et al, 2003]. Therefore, PGD for chromosomal aneuploidy allows avoiding from transfer of at least 50% of embryos, which are abnormal and should clearly contribute to the pregnancy outcome of the IVF patients of advanced reproductive age.…”

“…Finally, the patients should be also informed about the high aneuploidy rates in oocytes and embryos, as well as about the prevalence of mosaicism at the cleavage stage [Gianaroli et al, 2001; Munne, 2002; Kuliev et al, 2003]. In this way they may choose testing for aneuploidy at least for the chromosome, in which the causative gene tested is mapped, which may be of special value in PGD for single gene disorders offered for patients of the advanced reproductive age.…”

A silicone resin with silphenylene units in Si-O-Si backbones was synthesized by hydrolysis-polycondensation of 1,4-bis(hydroxydimethylsilyl)benzene (BHB) with chlorosilanes. The structure and property of this novel silicone resin were characterized by gel permeation chromatography (GPC), Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR), thermogarvimetric analysis (TG), scanning electron microscope (SEM), and electrochemical impedance spectrum (EIS). This silicone resin could be applied as the film forming material of coating when it is prepared under the condition of R/Si, Ph/R, and the content of silphenylene units being 1.3, 0.5, and 10 mol %, respectively. GPC, IR, and NMR results show that the silphenylene units have been incorporated into the polymer of silicone resin. The TG analysis indicates that this novel silicone resin has good heat resistance with the onset degradation temperature of 500.3 C and residual weight of 85.6% at 900 C. SEM results demonstrate that the silicone resin with silphenylene units can form full and uniform films, and its surface morphology of clear paints were not damaged by heat below 350C. EIS analysis reveals that clear paints of the silicone resin with silphenylene units have good resistance to corrosion.

“…Diese sind zum überwiegenden Teil auf chromosomale Veränderungen der Gameten zurückzuführen. Die Bedeutung der Polkörperdiagnostik bei älteren Frauen im Kinderwunschklientel wird klar, wenn man berücksich-tigt, dass nur 2-4% der Spermien eine Chromosomenaberration aufweisen, aber bis zu 40% der Eizellen von solchen genetischen Veränderungen betroffen sind und letzteres sehr stark altersabhängig ist [3, 11, [23][24][25][26][27][28][29][30][31][32][33] …”
