Expected coalescence times and segregating sites in a model of glacial cycles
Authors: F.F. Jesus, J.F. Wilkins, V.N. Solferini and J. Wakeley
The climatic fluctuations of the Quaternary have influenced the distribution of numerous plant and animal species. Several species suffer population reduction and fragmentation, becoming restricted to refugia during glacial periods and expanding again during interglacials. The reduction in population size may reduce the effect.. Read More»

Genetic trend for milk yield in Guzerat herds participating in progeny testing and MOET nucleus schemes
Authors: M.G.C.D. Peixoto, R.S. Verneque, R.L. Teodoro, V.M. Penna and M.L.Martinez
Genetic trends for 305-day milk yield (P305) in Brazilian Guzerat herds under selection were compared. Data from 4898 lactations of 3179 purebred and crossbred cows from various regions of Brazil were used. Milk yield was adjusted for mature age and the contemporary groups were defined as herd and calving year. Genetic paramet.. Read More»

Screening for fragile X syndrome among Brazilian mentally retarded male patients using PCR from buccal cell DNA
Authors: D.M. Christofolini, M.V.N. Lipay, M.A.P. Ramos, D. Brunoni and M.I. Melaragno
Fragile X syndrome is one of the most frequent causes of mental retardation. Since the phenotype in this syndrome is quite variable, clinical diagnosis is not easy and molecular laboratory diagnosis is necessary. Usually DNA from blood cells is used in molecular tests to detect the fragile X mutation which is characterized by .. Read More»

Evaluation of DNA polymorphisms involving growth hormone relative to growth and carcass characteristics in Brahman steers
Authors: V.R. Beauchemin, M.G. Thomas, D.E. Franke2 and G.A. Silver
Associations of DNA polymorphisms in growth hormone (GH) relative to growth and carcass characteristics in growing Brahman steers (N = 324 from 68 sires) were evaluated. Polymorphisms were an Msp-I RFLP and a leucine/valine SNP in the GH gene as well as a Hinf-I RFLP and a histidine/arginine SNP in transcriptional regulators o.. Read More»

Determination of ancestral proportions in synthetic bovine breeds using commonly employed microsatellite markers
Authors: H.M.S. Bicalho, C.G. Pimenta, I.K.P. Mendes, H.B. Pena, E.M. Queiroz and S.D.J. Pena
The International Society of Animal Genetics (ISAG) has chosen nine microsatellites (international marker set) as a standard that should be included in all cattle parentage studies. They are BM1824, BM2113, INRA023, SPS115, TGLA122, TGLA126, TGLA227, ETH10, and ETH225. We decided to ascertain whether this microsatellite set co.. Read More»

First report of major histocompatibility complex class II loci from the Amazon pink river dolphin (genus Inia)
Authors: M. MartÃ?Ânez-AgÃ?¼ero, S. Flores-RamÃ?Ârez and M. Ruiz-GarcÃ?Âa
We report the first major histocompatibility complex (MHC) DQB1 sequences for the two species of pink river dolphins (Inia geoffrensis and Inia boliviensis) inhabiting the Amazon and Orinoco River basins. These sequences were found to be polymorphic within the Inia genus and showed shared homology with cetacean DQB- 1 sequence.. Read More»

Association of BoLA-DRB3.2 alleles with tick (Boophilus microplus) resistance in cattle
Authors: M.L. Martinez, M.A. Machado, C.S. Nascimento, M.V.G.B. Silva, R.L. Teodoro, J. Furlong, M.C.A. Prata, A.L. Campos, M.F.M. Guimar�£es, A.L.S. Azevedo, M.F.A. Pires and R.S. Verneque
Losses caused by bovine tick burdens in tropical countries have a tremendous economic impact on production systems. Besides reducing production, this parasite can cause death in the most susceptible animals. The use of commercial acaricides has been the major method of control, but their misuse has led to tick resistance to ma.. Read More»

Evaluation of the humoral immune response in BALB/c mice immunized with a naked DNA vaccine anti-methicillin-resistant Staphylococcus aureus
Authors: D.M. Roth, J.P.M. Senna and D.C. Machado
Methicillin-resistant Staphylococcus aureus (MRSA) is the major pathogen involved in nosocomial infections, leading to high rates of morbidity and mortality in hospitals worldwide. The methicillin resistance occurs due to the presence of an additional penicillin-binding protein, PBP2a, which has low affinity for β-lactam .. Read More»
