Reproductive outcomes in recurrent pregnancy loss associated with a parental carrier of chromosome abnormalities or polymorphisms
Authors: Y. Dong, L.L. Li, R.X. Wang, X.W. Yu, X. Yun and R.Z. Liu
The subsequent reproductive outcomes in couples with a history of recurrent pregnancy loss (RPL) associated with chromosome abnormalities or polymorphisms are generally not reported in China. Many RPL carrier couples have decided not to have children. The present study recorded the subsequent delivery, miscarriage, and unpregn.. Read More»

Analysis of the genetic diversity of Chinese native Cannabis sativa cultivars by using ISSR and chromosome markers
Authors: L.G. Zhang, Y. Chang, X.F. Zhang, F.Z. Guan, H.M. Yuan, Y. Yu and L.J. Zhao
Hemp (Cannabis sativa) is an important fiber crop, and native cultivars exist widely throughout China. In the present study, we analyzed the genetic diversity of 27 important Chinese native hemp cultivars, by using inter-simple sequence repeats (ISSR) and chromosome markers. We determined the following chromosome formulas: 2n = 20 = 14m + 6sm; 2n = 20 = 2.. Read More»

Correlation between chromosomal polymorphisms and male infertility in a Northeast Chinese population
Authors: L.L. Li, D. Peng, R.X. Wang, H.B. Zhu, W.J. Wang, R.Z. Liu
The aim of this study was to evaluate the correlation between chromosomal polymorphisms and male infertility. The patients were diagnosed with azoospermia or oligospermiaby a semen analysis. Chromosomal analysis was performed on peripheral blood lymphocytes obtained from the patients, with standard G-banding and C-banding. Y c.. Read More»

`Identification of the origin of marker chromosomes by two-color fluorescence in situ hybridization and polymerase chain reaction in azoospermic patients
Authors: C.L. Wei1, J.L. Cheng, W.C. Yang, L.Y. Li, H.C. Cheng and J.J. Fu1
Y chromosomal microdeletions at the azoospermia factor locus and chromosome abnormalities have been implicated as the major causes of idiopathic male infertility. A marker chromosome is a structurally abnormal chromosome in which no part can be identified by cytogenetics. In this study, to identify the origin of the marker chromosomes and to perform a gen..

Is there a relationship between polyploidy and stressful environments? A case study of inselbergs in northeastern Brazil
Authors: S.R. Pitrez, L.A. Andrade, F.N.M. Assis and L.P. Felix
The aim of this study was to examine the hypothesis that plants with higher ploidy levels are selected by environments under more extremely stressful conditions than the same (or closely related) species from less rigorous terrestrial or epiphytic habitats. Therefore, we analyzed the chromosome numbers of 26 species belonging to 21 genera and 13 families .. Read More»

Detection of Y chromosome microdeletions and mitochondrial DNA mutations in male infertility patients
Authors: A.I. G�?¼ney, D. Javadova, D. K�?±rac, K. Ulucan, G. Koc, D. Ergec, H. Tavukcu and T. Tarcan
Infertility affects about 10-15% of all couples attempting pregnancy with infertility attributed to the male partner in approximately half of the cases. Proposed causes of male infertility include sperm motility disturbances, Y chromosome microdeletions, chromosomal abnormalities, single gene mutations, and sperm mitochondrial.. Read More»

Characterization of allele-specific expression of the X-linked gene MAO-A in trophectoderm cells of bovine embryos produced by somatic cell nuclear transfer
Authors: A.R. Ferreira, L.F.C. Aguiar Filho, R.V. Sousa, R. Sartori and M.M. Franco
Somatic cell nuclear transfer (SCNT) may affect epigenetic mechanisms and alter the expression of genes related to embryo development and X chromosome inactivation (XCI). We characterized allele-specific expression of the X-linked gene monoamine oxidase type A (MAO-A) in the trophectoderm (TF) of embryos produced by SCNT. Tota.. Read More»

A framework radiation hybrid map of buffalo chromosome 1 ordering scaffolds from buffalo genome sequence assembly
Authors: N.B. Stafuzza, B.C.M. Naressi, E. Yang, J.J. Cai and M.E.J. Amaral-Trusty
River buffalo chromosome 1 (BBU1) is a sub-metacentric chromosome homologous to bovine chromosomes 1 and 27. In this study, we constructed a new framework radiation hybrid (RH) map from BBU1 using BBURH5000 panel adding nine new genes (ADRB3, ATP2C1, COPB2, CRYGS, P2RY1, SLC5A3, SLC20A2, SST, and ZDHHC2) and one microsatellite (CSSM043) to the set of mark..

Genetic anomalies in patients with severe oligozoospermia and azoospermia in eastern Turkey: a prospective study
Authors: G.G. Ceylan1, C. Ceylan2 and H. Elyas3
Infertility is defined as the inability to conceive a child after one year of regular unprotected intercourse; it is a major health problem affecting about 10-15% of all couples. Infertility is due to a male factor in approximately 50% of cases. The human Y chromosome contains genes necessary for gonadal differentiation into a testis and genes for complet.. Read More»

Origin of a polyploid accession of Brachiaria humidicola (Poaceae: Panicoideae: Paniceae)
Authors: K.R. Boldrini1, P.L. Micheletti1, P.H. Gallo1, A.B. Mendes-Bonato1,M.S. Pagliarini1 and C.B. Valle2
Brachiaria humidicola, a species adapted to poorly drained and infertile acid soils, is widely used throughout the tropics. Cytological characterization of 54 accessions of B. humidicola for breeding purposes revealed 2n = 36, 42, and 54 chromosomes. One accession (H030), with 2n = 42 chromosomes, showed a different meiotic behavior. In most accessions fr.. Read More»
