    Notes: Abstract Methanol extracts of the green algaUlva pertusa contain four kinds of glycerolipids that are active as feeding-stimulants for marine herbivorous gastropods. These compounds are digalactosyldiacylglycerol (DGDG), 1,2-diacylglycerly-4′-O-(N,N,N-trimethyl)-homoserine (DGTH), 1-monoacylglyceryl-4'-O-(N,N,N-trimethyl)-homoserine (MGTH), and 6-sulfoquinovosyldiacylglycerol (SQDG). The various gastropods exhibit marked specificity, however, as young abaloneHaliotis discus respond to DGDG and DGTH at minute dosages of 20–30 μg/sample zone, but do not respond to 300 μg of SQDG, which is a phagostimulant for two other kinds of gastropods,Turbo comutus andOmphalius pfeifferi.

    Molecular analysis of familial androgen insensitivity syndrome due to replacement of glutamic acid 802 by lysine (2000)
    Springer
    Journal of human genetics 45 (2000), S. 342-345

    ISSN: 1435-232X

    Notes: Abstract We studied a Japanese family presenting at least two cases of complete androgen insensitivity syndrome (CAIS) and negative androgen receptor binding. The index subject showed a 46, XY karyotype and a complete female phenotype. For the purpose of further diagnosis and genetic counseling, molecular analysis of the androgen receptor (AR) gene was performed. Direct sequencing of the AR gene identified a mutation at nucleotide 2935 (A → G). This replacement was a novel missense mutation, resulting in the substitution of glutamic acid 802 by lysine which deleted a recognition site for EcoRI in exon 6 of the AR gene. We identified another affected individual, using chromosome and molecular analysis of the AR gene at exon 6. Furthermore, although heterozygote carriers could not be identified on clinical grounds, molecular identification of healthy individuals and heterozygote carriers in the family members provided definitive information for genetic counseling. We believe that the molecular analysis of familial CAIS is very informative for both the affected individuals and other family members.
