Isolation and characterization of novel microsatellite markers from Siamese fighting fish (Betta splendens, Osphronemidae, Anabantoidei) and their transferability to related species, B. smaragdina and B. imbellis
Authors: V. Chailertrit, A. Swatdipong, S. Peyachoknagul, J. Salaenoi and K. Srikulnath
Ten novel microsatellite markers were developed and characterized from Siamese fighting fish (Betta splendens). Nine of ten markers were polymorphic, exhibiting an allelic number (NA) from 2 to 6 alleles per locus. The effective number of alleles (NE) ranged from 1.60 to 3.08 (average of 2.30). The observed (HO) and expected (.. Read More»

Authors: B.P. Hoh, S.S. Siraj, S.G. Tan and K. Yusoff
The river catfish Mystus nemurus is an important fresh water species for aquaculture in Malaysia. We report the first genetic linkage map of M. nemurus based on segregation analysis and a linkage map using newly developed microsatellite markers of M. nemurus. A total of 70 of the newly developed polymorphic DNA microsatellite markers were analyzed on pedi.. Read More»

Characterization and description of a multiple sex chromosome system in Potamotrygon motoro (Chondrichthyes, Myliobatiformes) from the Paran�¡ River, Argentina
Authors: D.R. Aichino, M.C. Pastori, H.A. Roncati, M.A. Ledesma, A.C. Swar�§a and A.S. Fenocchio
The Potamotrygonidae family represents the only freshwater group of specialized elasmobranchs and is composed of 4 genera: Plesiotrygon, Paratrygon, Potamotrygon, and Heliotrygon. Individuals of Potamotrygon motoro were collected from the Paraná River at Ituzaingó (Province of Corrientes) in Argentina. Mitotic preparations were obtained usin.. Read More»

Numerical aberrations of chromosome 17 and TP53 in brain metastases derived from breast cancer
Authors: D.S. Vasconcelos, F.P.E. da Silva, L.G. Quintana, N.P. Anselmo, M.A.K. Othman, T. Liehr and E.H.C. de Oliveira
Breast cancer is the second most common origin of brain metastases, after lung cancer, and represents 14-20% of all cases. Abnormalities of chromosome 17 are important molecular genetic events in human breast cancer, and several oncogenes and tumor suppressor genes are located on this chromosome. In about half of all human cancers, the tumor suppressor ge.. Read More»

Inverted migration of rare whisker sheatfish in Nong-Han Lake, northeastern Thailand: Implications for conservation
Authors: P. Phongkaew, U. Arunyawat, A. Swatdipong and V. Hongtrakul
Nong-Han Lake, Thailand, sustains the whisker sheatfish (Micronema bleekeri Günther, 1864), which is a rare species of freshwater catfish. Wild-caught whisker sheatfish has been intensively harvested to meet market demand; yet, genetic information about this species remains unknown. To assist with the in situ.. Read More»

Impacts of stocking on the genetic diversity of Colossoma macropomum in central Amazon, Brazil
Authors: C.A. de Queiroz, N.R. Sousa, G.F. da Silva and L.A.K.A. Inoue
Tambaqui (Colossoma macropomum) is the main fish species farmed on a commercial scale in northern Brazil. In view of the current scenario of Brazilian aquaculture, studies on the genetic improvement and reproductive management of captive tambaqui are crucial in identifying the genetic variability of broodstocks and devising ma..

Fourteen years after the Shahid-Rajaei dam construction: an evaluation of morphometric and genetic differentiation between isolated up- and downstream populations of Capoeta capoeta gracilis (Pisces: Cyprinidae) in the Tajan River of Iran
Authors: Hossein AnvariFar, H. Farahmand, D.M. Silva, R.P. Bastos, A. Khyabani and Hassan AnvariFar
We evaluated the effects of the Shahid-Rajaei dam, 14 years after its construction, on morphometric and genetic divergence between up- and downstream populations of the Iranian fish Siah-Mahi (Capoeta capoeta gracilis). Sixty-six specimens were analyzed. There were significant differences between the 2 groups in the means of 16 morphometric characters (un.. Read More»

A rare case of trisomy 11q23.3-11q25 and trisomy 22q11.1-22q11.21
Authors: P.-S. Zou, H.-F. Li, L.-S. Chen, M. Ma1, X.-H. Chen, D. Xue and D.-H. Cao
Partial duplication of the long arm of chromosome 11 and the partial trisomy of 22q are uncommon karyotypic abnormalities. Here, we report the case of a 6-year-old girl who showed partial trisomy of 11q and 22q, as a result of a maternal balanced reciprocal translocation (11;22), and exhibited dysmorphic features, severe intel..

Cytogenetic toxicity and gonadal effects of 17 �±-methyltestosterone in Astyanax bimaculatus (Characidae) and Oreochromis niloticus (Cichlidae)
Authors: C.L.G. Rivero-Wendt, A.L. Miranda-Vilela, M.F.N. Ferreira, A.M. Borges and C.K. Grisolia
The synthetic hormone, 17-α-methyltestosterone (MT), is used in fish hatcheries to induce male monosex. Androgenic effects on various fish species have been reported; however, few studies have assessed possible genotoxic effects, although there are concerns about such effects in target and non-target species. We evaluated genotoxic and gonadal effec.. Read More»
