Cytogenetic characterization of Crenicichla (Pisces, Perciformes, Cichlidae) of the Igua�§u River
Authors: S.M.H.K. Mizoguchi, A.L.B. Portela-Castro, I.C. Martins-Santos
Three populations of the genus Crenicichla, namely Crenicichla iguassuensis, Crenicichla sp 1 and Crenicichla sp 2, from the Iguaçu River, were analyzed cytogenetically, and their nucleolus organizer regions, constitutive heterochromatin distribution and chromomycin A3 markings were studied. Karyotype analyses showed a .. Read More»

Movement patterns and genetic diversity of wild and reintroduced common dormice, Muscardinus avellanarius....
Authors: D.M. Naim, S. Telfer, S. Tatman, S. Bird, S.J. Kemp and P.C. Watts
Movement is an important life history trait that can have an impact on local adaptation, and other evolutionary phenomena. We used a combination of nestbox survey data and genetic techniques (genotyping at 10 microsatellite loci) to quantify patterns of movement in common dormice Muscardinus avellanarius at two distinct sites ..

Localization of HSP single-copy genes by inexpensive, permanent non-fluorescent in situ hybridization on meiotic chromosomes of the grasshopper Schistocerca pallens (Acrididae)
Authors: T.T. Rieger, S.V. Oliveira-Silva, I.A. Pach�ªco, B.S. Chagas, J.F. Santos
There have been many studies on Schistocerca gregaria and Locusta migratoria, which are important grasshopper pests in many parts of the world. However, the main pest grasshopper species in Brazil, S. pallens, Rhammatocerus schistocercoides and Stiphra robusta, are very poorly characterized genetically. We adapted a permanent .. Read More»

Protocol to cryopreserve and isolate nuclei from adipose tissue without dimethyl sulfoxide
Authors: M.M. Almeida1, L.C.J. Caires1, C.M. Musso1, J.M.S. Campos1, C.M.C. Maranduba1, G.C. Macedo2, J.P.R.F. Mendon�§a3 and R.M.G. Garcia1
Cryopreservation injuries involve nuclear DNA damage. A protocol for cryopreserving and isolating adipocyte nuclei is proposed. Adipose tissue samples were directly analyzed (NoCRYO-0h), or stored at -196°C for 7 days without 10% dimethyl sulfoxide (DMSO) (CRYO-WO-DMSO) or with DMSO (CRYO-W-DMSO). To determine the effect of DMSO on cryopreservation tr.. Read More»

Bionomics and sociological aspects of Euglossa fimbriata (Apidae, Euglossini)
Authors: S.C. Augusto and C.A. Gar�³falo
The nesting biology and the social structure of Euglossa fimbriata were studied based on two original nests found on the campus of the University of São Paulo, Ribeirão Preto, Brazil. Nest 1 contained two inseminated females, 39 sealed cells, one cell being provisioned, and six old and empty cells. Nest 2 contain.. Read More»

Polymorphic microsatellite markers in the false kelpfish Sebastiscus marmoratus: isolation, characterization, and cross-species amplification
Authors: H.B. Liu, S.F. Liu, J.B. Ye, Y.J. Yuan, S.X. Dingand Z.M. Zhuang
A (GT/CA)13-microsatellite-enriched genomic library of the false kelpfish Sebastiscus marmoratus was constructed, and 20 polymorphic microsatellite loci were isolated and characterized. The polymorphisms were investigated in 48 wild individuals from a single population collected from the northern Yellow Sea. The numbers of all.. Read More»

Male sleeping aggregations of solitary oil-collecting bees in Brazil (Centridini, Tapinotaspidini, and Tetrapediini; Hymenoptera: Apidae)
Authors: I. Alves-dos-Santos, M.C. Gaglianone, S.R.C. Naxara and M.S. Engel
Males of solitary bees usually spend the night in clusters on small branches of plants, cavities and flowers. The individuals usually return to the same location each evening during their life, exhibiting site fidelity to a particular plant. We report on the sleeping roosts of the males of some oil-collecting bees of the gener.. Read More»

Differentiation and evolutionary relationships in Erythrinus erythrinus (Characiformes, Erythrinidae): occurrence and distribution of B chromosomes
Authors: N.F. Martins, M.B. Cioffi, W.P. Troy, J.F. Martinez, O. Moreira-Filho and L.A.C. Bertollo
Erythrinus erythrinus, a Neotropical fish species of the Erythrinidae family, has a wide distribution in South America. Previous cytogenetic analysis showed that this species presents extensive karyotype diversity, with 4 karyomorphs (A-D) described herein. This study investigated the karyotypic structure of 2 new pop.. Read More»

Comparative study of leptin and leptin receptor gene expression in different swine breeds
Authors: S.E. Georgescu, M.A. Manea, S. Dinescu and M. Costache
Leptin is an important regulator of appetite, energy metabolism, and reproduction and is mainly synthesized in the adipocytes and then secreted into the bloodstream. The leptin receptor was classified as type I cytokine receptor due to its structural homology with IL-6 receptors and the signaling pathways in which they are bot.. Read More»

Analysis of p53 codon 72 gene polymorphism in Brazilian patients with endometriosis
Authors: C.L. Ribeiro J�ºnior, J.T. Arruda, C.T.X. Silva andK.K.V.O. Moura
We examined the frequency of p53 codon 72 polymorphism in 38 patients with endometriosis whose diagnosis was confirmed using videolaparoscopy. Half of the women were infertile. There were no significant differences in the genotype (P = 0.0927) or allele frequencies (P = 0.1430) for p53 Arg72Pro polymorphism between the two gro.. Read More»
