Cytogenetic and random amplified polymorphic DNA analysis of Leptodactylus species from rural and urban environments (Anura, Amphibia)
Authors: M.P. Arruda and E. Morielle-Versute
Cytogenetic and random amplified polymorphic DNA analyses carried out in the species Leptodactylus podicipinus, L. ocellatus, L. labyrinthicus, and L. fuscus from rural and urban habitats of the northwest region of São Paulo State, Brazil, showed that the karyotypes (2n = 22), constitutive heterochromatin distribution and nucleolus organizer region..

Selection of DNA barcoding loci and phylogenetic study of a medicinal and endemic plant, Plectranthus asirensis J.R.I. Wood from Saudi Arabia
Authors: F. Al-Qurainy, S. Khan, M. Nadeem, M. Tarroum and A. Al-Ameri
Genuine medicinal plant materials are very important for potential crude drug production, which can be used to cure many human diseases. DNA barcoding of medicinal plants is an effective way to identify adulterated or contaminated market materials, but it can be quite challenging to generate barcodes and analyze the data to de..

DNA repair by polymerase �´ in Saccharomyces cerevisiae is not controlled by the proliferating cell nuclear antigen-like Rad17/Mec3/Ddc1 complex
Authors: J.M. Cardone, M. Brendel and J.A.P. Henriques
DNA damage activates several mechanisms such as DNA repair and cell cycle checkpoints. The Saccharomyces cerevisiae heterotrimeric checkpoint clamp consisting of the Rad17, Mec3 and Ddc1 subunits is an early response factor to DNA damage and activates checkpoints. This complex is structurally similar to the proliferating cell nuclear antigen (PCNA), which.. Read More»

Gene expression analysis of demineralized bone matrix-induced osteogenesis in human periosteal cells using cDNA array technology
Authors: S. Honsawek, P. Bumrungpanichthaworn, T. Thitiset and L. Wolfinbarger Jr.
Demineralized bone matrix (DBM) has been widely investigated as a biomaterial to promote new bone formation and is utilized clinically for bone repair and regeneration. We investigated gene expression patterns of osteogenic differentiation in human periosteal (HPO) cells cultured with demineralized bone matrix, using cDNA arra.. Read More»

Molecular variability in Brycon cf. pesu M�¼ller and Troschel, 1845 (Characiformes: Characidae) from the Araguaia-Tocantins basin
Authors: R.S. Panarari-Antunes, A.J. Prioli, S.M.A.P. Prioli, H.F. J�ºlio Jr. C.S. Agostinho and L.M. Prioli
Brycon pesu is a small-sized fish distributed throughout the Amazon and Orinoco Basins and other coastal basins of northeastern South America. Brycon cf. pesu specimens from the Araguaia-Tocantins Basin are currently separated into two morphotypes, Brycon sp1 and Brycon sp2, owing to different coloration of their anal fin. Brycon sp2 has a reddish margin .. Read More»

ABO genotyping in leukemia patients reveals new ABO variant alleles
Authors: M.C.Z. Novaretti, A.E. Domingues, R. Manhani, E.M. Pinto, P.E. Dorlhiac-Llacer and D.A.F. Chamone
The ABO blood group is the most important blood group system in transfusion medicine and organ transplantation. To date, more than 160 ABO alleles have been identified by molecular investigation. Almost all ABO genotyping studies have been performed in blood donors and families and for investigation of ABO subgroups detected serologically. The aim of the .. Read More»

Identification of actinomycete communities in Antarctic soil from Barrientos Island using PCR-denaturing gradient gel electrophoresis
Authors: L. Learn-Han, C. Yoke-Kqueen, M.S. Shiran, C.M.W. Vui-Ling, A.M. Nurul-Syakima, R. Son and H.M. Andrade
The diversity of specific bacteria taxa, such as the actinomycetes, has not been reported from the Antarctic island of Barrientos. The diversity of actinomycetes was estimated with two different strategies that use PCR-denaturing gradient gel electrophoresis. First, a PCR was applied, using a group-specific primer that allows ..

Mutual information content of homologous DNA sequences
Authors: Helena Cristina G. Leit�£o, Luciana S. Pess�´a and Jorge Stolfi
The necessary information to reproduce and keep an organism is codified in acid nucleic molecules. Deepening the knowledge about how the information is stored in these bio-sequences can lead to more efficient methods of comparing genomic sequences. In the present study, we analyzed the quantity of information contained in a DN.. Read More»

The mutation G298A�Ala100Thr on the coding sequence of the Duffy antigen/chemokine receptor gene in non-caucasian Brazilians
Authors: Angela Cristina Estalote, Rodrigo Proto-Siqueira, Wilson Ara�ºjo Da Silva Jr., Marco Antonio Zago and Marcos Palatnik
Ala100Thr has been suggested to be a Caucasian genetic marker on the FY*B allele. As the Brazilian population has arisen from miscegenation among Portuguese, Africans, and Indians, this mutation could possibly be found in Euro- and Afro-Brazilians, or in Brazilian Indians. Fifty-three related individuals and a random sample of.. Read More»

Allele frequencies for 12 autosomal short tandem repeat loci in two bolivian populations
Authors: L. Cifuentes, H. Jorquera, M. Acu�±a, J. Ord�³�±ez and A.L. Sierra
Two hundred and sixty unrelated subjects who asked for paternity testing at two Bolivian Laboratories in La Paz and Santa Cruz were studied. The loci D3S1358, vWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820, TH01, TPOX, and CSF1PO were typed from blood samples, amplifying DNA by polymerase chain reactions and electr..
