[Improved identification for 5p deletion syndrome and partial trisomy 11q presented in a fetus by SNP array].

Objective: To investigate the prenatal application of single nucleotide polymorphism array (SNP array) in the identification of 5p deletion syndrome with partial trisomy 11q.

Methods: G-banded karyotyping and SNP array were performed using amniocytes on a fetus with multiple malformations for the identification of chromosome abnormality. Furthermore, karyotyping was carried out on the parental peripheral blood specimens to ascertain the origin of chromosome abnormalities and then fluorescence in situ hybridization (FISH) was also utilized to confirm the results.

Physicochemical properties of corn stalk after treatment using steam explosion coupled with acid or alkali.

The aim of this study was to evaluate comparatively the effects of different pretreatments including steam explosion, acid, and alkali, alone or in combination, on the structural properties and thermal stability of corn stalk. All of the treated treatments decreased the contents of hemicellulose and lignin and thereby increased the content of cellulose in corn stalks. But the combined treatments with alkali and steam explosion under 0.
