Buccal micronucleus frequency is associated with age in Down syndrome
Authors: F.L.S. Ferreira, D. PrĂ?¡, M.G. Martino-Roth and G.L. Garcias
Down syndrome has been linked to premature aging and genomic instability. We examined the frequency of micronucleus (MN) and binucleated cells in the oral mucosa of Down syndrome patients and healthy controls matched by age and gender, addressing the effect of age and family income. Down syndrome individuals had an increased n.. Read More»

FISH analysis and cytogenetic characterization of male meiotic prophase I in Acricotopus lucidus (Diptera, Chironomidae)
Authors: W. Staiber
In the chironomid Acricotopus lucidus, two cells with quite different chromosome complements arise from the last unequal spermatogonial mitosis, as a consequence of monopolar migration of the so-called germ line limited chromosomes (Ks). The cell receiving all the Ks, in addition to two sets of the regularly segregating somati.. Read More»

Cytogenetic findings in an epithelioid sarcoma with angiomatoid features. A case report
Authors: M.S. Brassesco, E.T. Valera, A.M. Castro-Gamero, D.A. Moreno,T.P. Silveira, B.M. Mori, E.E. Engel4, C.A. Scrideli and L.G. Tone
Epithelioid sarcoma is a rare, aggressive soft tissue tumor of unknown histogenesis showing predominantly epithelioid cytomorphology. We conducted a conventional and molecular cytogenetic study of a 27-year-old male with epithelioid sarcoma with angiomatoid features. Cytogenetic analysis of epithelioid sarcoma metaphase spread..

Potential use of molecular markers for prediction of genotypic values in hybrid maize performance
Authors: M. Balestre, R.G. Von Pinho, J.C. Souza and R.L. Oliveira
We evaluated the potential of genetic distances estimated by microsatellite markers for the prediction of the performance of single-cross maize hybrids. We also examined the potential of molecular markers for the prediction of genotypic values and the applicability of the Monte Carlo method for a correlation of genetic distanc.. Read More»

Genotypic stability and adaptability in tropical maize based on AMMI and GGE biplot analysis
Authors: M. Balestre, R.G. Von Pinho, J.C. Souza and R.L. Oliveira
We evaluated the phenotypic and genotypic stability and adaptability of hybrids using the additive main effect and multiplicative interaction (AMMI) and genotype x genotype-environment interaction (GGE) biplot models. Starting with 10 single-cross hybrids, a complete diallel was done, resulting in 45 double-cross hybrids that .. Read More»

Cytogenetic and molecular analysis of an apomictic cassava hybrid and its progeny
Authors: N.M.A. Nassar, P.T.C. Gomes, A.M. Chaib1, N.N. Bomfim,R.C.D. Batista and R.G. Collevatti
An interspecific hybrid between cassava and Manihot glaziovii acquired an apomixis gene from the parent M. glaziovii. This hybrid was exposed to open pollination during three subsequent generations. Seven sibs and the maternal progenitor of the fourth generation were genotyped using six microsatellite loci previously developed.. Read More»
