the indications and results of cytogenetic analysis of 521 amniotic cell cultures performed at 13-16 weeks of gestation were evaluated in this study. 507 fetuses (97.3%) were cytogenetically normal, 14 (2.7%) had unbalanced karyotypes, and 2 fetuses were found to have major abnormalities, one with anencephaly detected by measurement of alpha -fetoprotein levels in amniotic fluid and ultrasonogr...
Triploidy is a lethal chromosomal abnormality. Foetuses with triploid condition have a tendency to die in early conception and very few survive to term. In this study, we report the prenatal diagnosis of fetal triploidy with unexpected chromosomal translocation. A 27 years old women was referred to our clinical cytogenetic department due to history of previous conceptus with intrauterine growth...
abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.

A 12 year old girl referred for chromosome analysis because of short stature was found to have karyotype mos 45,X/46,X,+mar. The marker chromosome was observed in 58% of her blood lymphocytes. It was a small, pale staining, spherical fragment with GTL banding and showed faint differentiation along its length with CBG banding. DNA analysis using Y specific probes showed the absence of the testic...
