Molecular Diagnosis of X-Fragile Syndrome: Perspectives for the Public Health System in the Central Region of Brazil
Authors: K.B. Penteado, C.I.S. Gressler, A.D. Da Cruz, T.C. Vieira, & M.A. D. Gigonzac
X-Fragile Syndrome (FXS) is the most common cause of inherited intellectual disability and the second of genetic origin, with an estimated prevalence of 1/4000 men and 1/6000 women. The etiology is associated with a trinucleotide expansion of CGG sequences and hypermethylation of the promoter region of the FMR1 (Fragile-X Ment.. Read More»

In vivo antimutagenic activity of the medicinal plants Pfaffia glomerata (Brazilian ginseng) and Ginkgo biloba
Authors: I.V. Almeida, E. D�?¼sman, G.I. Mattge, F. Toledo, A.F. Reusing and V.E.P. Vicentini
Complementary and alternative therapies, including the use of medicinal plants, have become almost standard among the world’s population. Pfaffia glomerata (PG), popularly known as Brazilian ginseng, is widely used as a restorer of vital functions, increasing mental balance, and is used for the treatment of diabetes and .. Read More»

Chemotherapeutical effects of the herbal medicine Uncaria tomentosa (Willd.) DC.
Authors: I.V. Almeida, L.C. Soares, F.T. Lucio, L.B. Cantagalli, A.F. Reusing and V.E.P. Vicentini
The use of medicinal plants dates back to the beginning of humanity, and today their application as complementary therapy has been widely disseminated as an alternative to conventional therapy. The medicinal plant named Uncaria tomentosa (Willd.) DC. (known as cat’s claw) is a common woody vine of the Amazon forest that .. Read More»

Contributions of classical and molecular cytogenetic in meiotic analysis and pollen viability for plant breeding
Authors: M.P. Lavinscky, M.M. Souza, G.S. Silva and C.A.F. Melo
The analysis of meiotic behavior has been widely used in the study of plants as they provide relevant information about the viability of a species. Meiosis boasts a host of highly conserved events and changes in genes that control these events will give rise to irregularities that can alter the normal course of meiosis and may.. Read More»

Chromosome variations and diversity of Epidendrum ibaguense Lindl. (Orchidaceae) on the Tepequ�?©mâ�?�?s Tepuy, Roraima, Brazil
Authors: S.R. N�?³brega, A.L.F. Coelho, C.F. Verola, I.R. Costa, R. Vila�?§a, F.J.F. Luz and W.F. Ara�?ºjo
Studies addressing chromosome variations have elucidated many points regarding the taxonomy of the Orchidaceae. Epidendrum L. besides being one the largest orchid genera, present remarkable morphological, and inter- and intraspecific chromosome variations. Thus, based on a previous report on flower color variation in individua.. Read More»

Intraspecific and interspecific polyploidy of Brazilian species of the genus Inga (Leguminosae: Mimosoideae)
Authors: M.F. Figueiredo, R.L.A. Bruno, A.E. Barros e Silva, S. Nascimento, I.G. Oliveira and L.P. Felix
We investigated the karyotypes of 13 species of six sections of the genus Inga (Leguminosae-Mimosoideae) from Brazil. We used conventional Giemsa staining to identify numerical chromosomal variations and looked for karyotypic evolutionary patterns. The karyotypes generally had small chromosomes, varying from metacentric to sub.. Read More»

Y-STR haplotype diversity and population data for Central Brazil: implications for environmental forensics and paternity testing
Authors: T.C. Vieira, M.A.D. Gigonzac, D.M. Silva, R.G. Rodovalho, G.S. Santos and A.D. da Cruz
The central region of Brazil was colonized by internal migration of individuals of different origins, who contributed to the genetic diversity existing in this population. This study determined the allele frequencies and haplotype diversity of Y-STRs in Goiás State, Central Brazil, and compared the data obtained with a .. Read More»

Male infertility in Northeast China: molecular detection of Y chromosome microdeletions in azoospermic patients with Klinefelter��?s syndrome
Authors: H.-G. Zhang, Z.-B. Zhang, R.-X. Wang, Y. Yu, X.-W. Yu, E. Fadlalla and R.-Z. Liu
The prevalence of microdeletions of azoospermia factor (AZF) among azoospermic Klinefelter’s syndrome (KFS) patients shows conflicting data. We aimed to detect this frequency in a Northeast Chinese population, and to investigate the possible association between AZF microdeletions and KFS by comparison with previous conflicting reports. Eighty men af.. Read More»
