Modeling of crossbred cattle growth, comparison between cubic and piecewise random regression models
Authors: H.R. Mirzaei, W.S. Pitchford and A.P. Verbyla
Two analyses, cubic and piecewise random regression, were conducted to model growth of crossbred cattle from birth to about two years of age, investigating the ability of a piecewise procedure to fit growth traits without the complications of the cubic model. During a four-year period (1994-1997) of the Australian “South.. Read More»

Gene expression in swine granulosa cells and ovarian tissue during the estrous cycle
Authors: P.V. Silva, S.E.F. Guimar?£es, J.D. Guimar?£es, J.B. Neto, P.S. Lopes, C.S. do Nascimento, C.F. de Campos, M.M.C.A. Weller, M.E. Botelho and V.R. Faria
The components of the insulin-like growth factor (IGF) system appear to be involved in regulation of ovarian follicular growth and atresia in the pig. We investigated the expression pattern of mRNAs for IGF1 (IGF1), its binding proteins (IGFBP1, IGFBP2, IGFBP3, and IGFBP5), and epidermal growth factor in swine follicle cells a.. Read More»

Genetic diversity in the Pantaneiro horse breed assessed using microsatellite DNA markers
Authors: E.H. Giacomoni, G.P. Fern?¡ndez-Stolz and T.R.O. Freitas
The genetic variability for a sample of 227 animals from three populations of Pantaneiro horses was estimated using data from 10 microsatellite loci. The number of alleles and the proportion of heterozygosity indicated high variability. A total of 91 alleles were found, with a significantly high mean number of alleles. The mea.. Read More»

Genetics of efficient feed utilization and national cattle evaluation: a review
Authors: D.H. â??Dennyâ? Crews Jr.
Selection for the wide range of traits for which most beef breed associations calculate expected progeny differences focus on increasing the outputs of the production system, thereby increasing the genetic potential of cattle for reproductive rates, weights, growth rates, and end-product yield. Feed costs, however, represent a.. Read More»

Assessing hygienic behavior of Apis mellifera unicolor (Hymenoptera: Apidae), the endemic honey bee from Madagascar
Authors: H. Rasolofoarivao, H. Delatte, L.H. Raveloson Ravaomanarivo,B. Reynaud and J. Cl?©mencet
Hygienic behavior (HB) is one of the natural mechanisms of honey bee for limiting the spread of brood diseases and Varroa destructor parasitic mite. Objective of our study was to measure HB of Apis mellifera unicolor colonies (N = 403) from three geographic regions (one infested and two free of V. destructor) in Madagascar. The pin-killing method was used.. Read More»

Genetic analysis of average annual productivity of Nellore breeding cows (COWPROD)
Authors: J.P. Eler, J.B.S. Ferraz, J.C.C. Balieiro and E.C. Mattos
With the aim of estimating the coefficient of heritability of average annual productivity of Nellore cows (COWPROD), a data set from 24,855 animals with known pedigree was analyzed. COWPROD is defined as the amount (in kilograms) of weaned calves produced yearly by one cow during her remaining time in herd ignoring a fixed.. Read More»

Nucleolar behavior during meiosis in four species of phyllostomid bats (Chiroptera, Mammalia)
Authors: M.R. Beguelini, S.R.C. Marchesin, M.T.V. Azeredo-Oliveira and E. Morielle-Versute
We analyzed the behavior of the nucleolus, nucleolar structures and nucleolus organizer regions (NORs) during meiotic division in four species of phyllostomid bats that have different numbers and locations of NORs. Nucleoli began disassembly at leptotene, and the subcomponents released from the nucleolus were dispersed in the .. Read More»

Detection of deletions and duplications in the Duchenne muscular dystrophy gene by the molecular method MLPA in the first Argentine affected families
Authors: D.M. Marzese, A. Mampel, L.C. Gomez, M.I. Echeverria,A.L. Vargas, V. Ferreiro, F. Giliberto and M. Roque?
Deletions/duplications in the Duchenne muscular dystrophy (DMD) gene account for 60 to 70% of all alterations. A new technique, multiplex ligation-dependent probe amplification (MLPA), has been described that allows the detection of large genetic rearrangements by simultaneous amplification of up to 45 target sequences. The pr.. Read More»

Pattern of GHR mRNA expression and body growth in the S2 line of sex-linked dwarf chickens
Authors: H.Y. Huang, Z.H. Zhao, S.F. Li, Z. Liang, C.M. Li and Q.B. Wang
Sex-linked dwarf (SLD) chickens have been widely used in cross breeding of broilers and laying hens. To study the molecular mechanisms underlying growth hormone receptor (GHR) in SLD chickens, the expression profiles of GHR were measured in three growth related tissues (liver, breast, and thigh) in male and female S2 SLD chick..

Molecular characterization and structure analysis of RPL10/QM-like protein from the red drum Sciaenops ocellatus (Sciaenidae)
Authors: X. Chen, C.-W. Wu, S.-P. Zhong, F.-R. Zeng, J.-S. Zhang, J. Wang and S.-F. Niu
The QM-like gene encodes a ribosomal protein L10. Besides housekeeping roles in protein synthesis, QM-like proteins have multiple extraribosomal functions during cell growth, cell differentiation and apoptosis. We obtained the full-length cDNA of QM-like protein (designated as SoQM) from the salt water game fish Sciaenops ocel.. Read More»
