Identification of aac(2')-I Type b aminoglycoside-modifying enzyme genes in resistant Acinetobacter baumannii
Authors: T. Lin, C.G. Tang, Q.H. Li, J. Ji, H.Y. Ge, X.Y. Zhang and H.P. Sun
The aim of this study was to investigate the mechanism underlying the drug resistance of Acinetobacter baumannii toward aminoglycosides. A total of 32 A. baumannii strains were identified by molecular identification and subsequently isolated. The isolates were then amplified by polymerase chain reaction to analyze the 9 aminoglycoside-modifying enzyme gen.. Read More»

Combining ability of tropical and temperate inbred lines of popcorn
Authors: V.Q.R. da Silva, A.T. do Amaral J�ºnior, L.S.A. Gon�§alves, S.P. Freitas J�ºnior, L.S. Candido, C. Vittorazzi, L.M. Moterle, R.A. Vieira and C.A. Scapim
In Brazil, using combining ability of popcorn genotypes to achieve superior hybrids has been unsuccessful because the local genotypes are all members of the same heterotic group. To overcome this constraint, 10 lines (P1 to P10) with different adaptations to tropical or temperate edaphoclimatic environments were used to obtain.. Read More»

Gene expression profiles of primary retinal pigment epithelial cells from apolipoprotein E knockout and human apolipoprotein E2 transgenic mice
Authors: D.H. Jo, J.H. Lee, H.J. Jun, J. Kim, Q. Wen, M.H. Hoang,Y.S. Yu, J.H. Kim and S.J. Lee
Age-related macular degeneration (AMD) causes visual impairment in the elderly. In non-neovascular AMD, studies involving human subjects have suggested potential involvement of aberrant lipid metabolism. However, there have been no reports on gene expression patterns in animal models of non-neovascular AMD with abnormal lipid metabolism such as apolipopro.. Read More»

IGF-I gene polymorphism, but not its blood concentration, is associated with milk fat and protein in Holstein dairy cows
Authors: E. Bonakdar, H.R. Rahmani, M.A. Edriss and B.E. Sayed Tabatabaei
We estimated the allele and genotype frequencies of IGF-I/SnaBI gene polymorphism and the concentration of this protein in Holstein dairy cows. We also examined the association with milk yield (305-day milk yield) and milk components (fat and protein percentage, and 305-day milk protein and fat yield). Blood IGF-I levels were .. Read More»

Sequence characterization and phylogenetic analysis of toll-like receptor (TLR) 4 gene in the Tibetan macaque (Macaca thibetana)
Authors: Q.X. Dai, Y.F. Yao, Z.C. Qi, Y. Huang, Q.Y. Ni, M.W. Zhang and H.L. Xu
In this study, the complete coding region sequence of an innate immune-related TLR4 gene was obtained from the Tibetan macaque (Macaca thibetana) genome via PCR and direct sequencing. The sequence had a total length of 2481 bp, contained 3 complete exons, and encoded 826 amino acids (AAs); its isoelectric point was 5.703, and the molecular weight was 94.7.. Read More»

�Ovar-Mhc� - ovine major histocompatibility complex: structure and gene polymorphisms
Authors: V.S.R. Dukkipati, H.T. Blair, D.J. Garrick and A. Murray
The major histocompatibility complex (MHC) in sheep, Ovar-Mhc, is poorly characterised, when compared to other domestic animals. However, its basic structure is similar to that of other mammals, comprising class I, II and III regions. Currently, there is evidence for the existence of four class I loci. The class II region is b.. Read More»

Gene flow from transgenic to nontransgenic soybean plants in the Cerrado region of Brazil
Authors: Abud S, de Souza PIM, Vianna GR, Leonardecz E, Moreira CT, Faleiro FG, Junior JN, Monteiro PMFO, Rech EL and Aragao FJL
Evaluation of transgenic crops under field conditions is a fundamental step for the production of genetically engineered varieties. In order to determine if there is pollen dispersal from transgenic to nontransgenic soybean plants, a field release experiment was conducted in the Cerrado region of Brazil. Nontransgenic plants w..

Genetic correlation between heifer pregnancy and scrotal circumference measured at 15 and 18 months of age in Nellore cattle
Authors: J.P. Eler, J.B.S. Ferraz, J.C.C. Balieiro, E.C. Mattos and G.B. Mour�£o
Data of pregnancy diagnosis from 24,945 Nellore heifers, raised under tropical conditions in Brazil and exposed to breeding at about 14 months of age, were analyzed simultaneously with 13,742 (analysis 1), 36,091 (analysis 2), 8,405 (analysis 3), and 8,405 (analysis 4) scrotal circumference (SC) records of contemporary young b..

Genetic diversity in wild (Sus scrofa scrofa) and domestic (Sus scrofa domestica) pigs and their hybrids based on polymorphism of a fragment of the D-loop region in the mitochondrial DNA
Authors: S.F. Grossi, J.F. Lui, J.E. Garcia and F.V. Meirelles
We examined the variation in mitochondrial DNA by sequencing the D-loop region in wild and domestic (large-white breed) pigs, in hybrids between domestic and wild pigs, and in Monteiro pigs. A D-loop fragment of approximately 330 bp was amplified by PCR. Sequencing of DNA amplicons identified haplotypes previously described as.. Read More»

Estimates of genetic parameters for Holstein cows for test-day yield traits with a random regression cubic spline model
Authors: DeGroot BJ, Keown JF, Van Vleck LD and Kachman SD
Genetic parameters were estimated with restricted maximum likelihood for individual test-day milk, fat, and protein yields and somatic cell scores with a random regression cubic spline model. Testday records of Holstein cows that calved from 1994 through early 1999 were obtained from Dairy Records Management Systems in Raleigh.. Read More»
