chromosome counting was performed in nine populations of achillea tenuifolia lam and eight populations of a. bieberestinii afan (asteraceae) collected from hamedan and kermanshah provinces in the west of iran. chromosome numbers in both species varied from 2n=2x=18 to 2n=4x=36. some populations of both species showed (2n=4x=36) chromosome number that is the first report as polyploidy levels. an...
There have been relatively few reports of individuals with double autosomal trisomy (Gagnon et al., 1961; Becker, Burke, and Albert, 1963; Hsu et al., 1965; Marks, Wiggins, and Spector, 1967). There have been rather more published accounts of individuals showing trisomy for one autosome and an additional chromosome in the sex chromosome complement as well. Of these, only those with the sex chro...
OBJECTIVE To provide Canadian health care providers with current information on the use of quantitative fluorescent polymerase chain reaction (QF-PCR) or equivalent technology in the prenatal diagnosis of fetal chromosomal abnormalities. OPTIONS Over the last few decades, prenatal diagnosis of fetal chromosomal abnormalities has relied on conventional cytogenetic analysis of cultured amniocyt...

PURPOSE To examine karyotype changes in cultured human corneal endothelial cells (HCECs). METHODS HCECs with Descemet's membrane were removed from 20 donors of various ages (range, 2-77 years; average, 43.7+/-26.4 years) and cultured on dishes coated with extracellular matrix produced by bovine corneal endothelial cells (BCECs). Karyotype changes were examined by G-band karyotyping of HCECs a...

Of the 65 328 pregnancies of South Australian mothers screened by the South Australian Maternal Serum Antenatal Screening (SAMSAS) Programme between 1 January 1991 and 31 December 1997, 3431 (5.25%) were declared at increased risk of fetal Down syndrome. Fetal or neonatal karyotype was determined in 2737/3431 (79.8%) of these pregnancies, including 16 with early fetal loss. Interrogation of the...
