Effect of intracellular Wolbachia on interspecific crosses between Drosophila melanogaster and Drosophila simulans
Authors: I.N. Gazla and M.C. Carracedo
Wolbachia are bacteria that live inside the cells of a large number of invertebrate hosts and are transmitted from infected females to their offspring. Their presence is associated with cytoplasmic incompatibility in several species of Drosophila. Cytoplasmic incompatibility results when the sperm of infected males fertilize eggs of uninfected females, ca.. Read More»

Behavior and viability of spontaneous oxidative stress-resistant Lactococcus lactis mutants in experimental fermented milk processing
Authors: M.N. Oliveira1, K.E. Almeida1, M.R. Damin1, T. Rochat2,J.-J. Gratadoux2, A. Miyoshi3, P. Langella2 and V. Azevedo3
Previously, we isolated two strains of spontaneous oxidative (SpOx2 and SpOx3) stress mutants of Lactococcus lactis subsp cremoris. Herein, we compared these mutants to a parental wild-type strain (J60011) and a commercial starter in experimental fermented milk production. Total solid contents of milk and fermentation temperature both affected the ac.. Read More»

PIT1 gene polymorphism in Pietrain and Large White pigs after divergent selection
Authors: A.C.P. Silveira1, T.F. Braga1, J.F. Almeida2, R.C. Antunes1,P.F.A. Freitas1, A.S.M. Cesar1 and E.C. Guimar�£es1
We examined the polymorphisms in the PIT1 gene of 103 pigs and compared their frequencies in the maternal and paternal lineages of the Pietrain and Large White breeds, which have undergone divergent selection for over 30 years. DNA samples extracted from the blood of these animals were amplified by PCR and genotyped by RFLP, using the restriction enzyme R.. Read More»

Study on the effects of blueberry treatment on histone acetylation modification of CCl4-induced liver disease in rats
Authors: W. Zhan, X. Liao, T. Tian, L. Yu, X. Liu, B. Li, J. Liu, B. Han, R.J. Xie, Q.H. Ji and Q. Yang
The objective of this study was to investigate the effects of blueberry treatment on histone acetylation modification of carbon tetrachloride (CCl4)-induced liver disease in rats. Laboratory rats were randomly divided into control, hepatic fibrosis, blueberry treatment, blueberry intervention, and natural recovery groups. Rats.. Read More»

Genetic correlations between mature cow weight and productive and reproductive traits in Nellore cattle
Authors: I.C. Regatieri A.A. Boligon F. Baldi L.G. Albuquerque
We investigated genetic associations between mature cow weight (MW) and weaning weight (WW), yearling weight (YW), weight gain from birth to weaning (GBW), weight gain from weaning to yearling (GWY), weaning hip height (WHH), yearling hip height (YHH), scrotal circumference (SC), and age at first calving (AFC). Data from 127,104 Nellore animals born between .. Read More»

Identification of the e allele at the Extension locus (MC1R) in Brazilian Creole sheep and its role in wool color variation
Authors: D. Hepp G.L. Gon�§alves G.R.P. Moreira T.R.O. Freitas C.T.D.C. Martins T.A. Weimer D.T. Passos
The melanocortin 1 receptor (MC1R) gene has been described as responsible for the black color in some breeds of sheep, but little is known about its function in many colored breeds, particularly those with a wide range of pigmentation phenotypes. The Brazilian Creole is a local breed of sheep from southern Brazil that has a wide variety of wool colors. We.. Read More»

Construction and preliminary characterization of a river buffalo bacterial artificial chromosome library
Authors: N.B. Stafuzza C.A. Abbey C.A. Gill J.E. Womack M.E.J. Amaral
River buffalo genome analyses have advanced significantly in the last decade, and the genome sequence of Bubalus bubalis will be available shortly. Nonetheless, large-insert DNA library resources such as bacterial artificial chromosomes (BAC) are still required for validation and accurate assembly of the genome sequence. We constructed a river buffalo BAC li.. Read More»

Morphology and muscle gene expression in GIFT and Supreme Nile tilapia varieties reared in two cultivation systems
Authors: E.C.S. Lima, J.A. Povh, R.A.A. Otonel, J.H. Leonhardt, A.A. Alfieri, S.A. Headley, F.P. Souza, A.R. Poveda-Parra, P.J. Furlan-Murari, N.M. Lopera-Barrer1
Tissue growth in most fishes occurs by muscular hyperplasia and hypertrophy, which are influenced by different regulatory factors, such as myostatin. The current study evaluated the influence of cultivation in hapas and earthen ponds on the diameter of white muscle fibers and on the myostatin (MSTN-1) gene in GIFT and Supreme .. Read More»

Nramp1 gene expression in different tissues of Meishan piglets from newborn to weaning
Authors: C.H. Dai, J.Y. Wu, C.X. Zhao, L.H. Yu, W.B. Bao and S.L. Wu
Natural resistance-associated macrophage protein gene 1 (Nramp1) plays an important role in the innate immune response of swine, and is believed to influence disease resistance. In this study, a real-time quantitative polymerase chain reaction technique was used to investigate Nramp1 expression in 12 different tissues in newbo.. Read More»
