We describe a 17 year old male with a low level of trisomy 9 mosaicism. Maternal uniparental chromosome 9 disomy in the euploid cell line was shown to have arisen after postzygotic loss of the paternal chromosome 9 from the trisomic cell line by cytogenetic and molecular analysis. This is believed to be the first report of uniparental disomy for chromosome 9. In four of the 11 reported cases of...

erodium (geranaiceae) species are distributed in different habitats of iran. some species are of medicinal importance while some are well known weeds. there are no chromosome counts for erdoium species of iran. chromosome numbers are given for six taxa of erodium (geraniaceae) from iran: e. cicutarium (2n=36), e. ciconium(2n=18), e. malacoides (2n=20), e. moschatum (2n=20), e. neuradifolium (2n...

To evaluate the practical value of natural beta-carotene (NbetaC) and to elucidate the apparent discrepancy between epidemiological observations and intervention trials on the role of beta-carotene (betaC) in tumor prevention, the genotoxicity and the antigenotoxicity of NbetaC and synthetic betaC crystal (SbetaCC) stereoisomers were studied comparatively using chromosome aberration analysis an...

The Breakpoint Cluster Region is a protein encoded by the BCR gene with its partially discovered function to generate instructions for producing and also encode serine/threonine kinase protein. There are three cluster regions; major (M-bcr) which high in CML patients, minor (m-bcr) 1-2% contribution CML, micro (μ-bcr) very rare case of CML. ABL1 encodes can as tyrosine kinase. translocation ABL...

Cytological, seed and epidermal studies were carried out of 9 taxa belonging to 4 genera 6 species the tribe Eupatorieae. Chromosome counts 2 species-Adenostemma caffrum (n=10) A. mauritianum are reported for first time from Nigerian flora report Ageratum conyzoides (n=18) differed earlier reports. The cytotypes in is flora. pollen fertility test all plants studied high this revealed that meios...
