Selection index based on the relative importance of traits and possibilities in breeding popcorn
Authors: R.A. Vieira, R. Rocha, C.A. Scapim, A.T. Amaral J�ºnior and M. Vivas
One of the major difficulties faced by popcorn breeders is the negative correlation between popping expansion (PE) and grain yield (GY). It is necessary to overcome this difficulty to obtain promising genotypes. One helpful tool in this process is a selection index because it allows multiple features of interest to be selected..

Detection of hepatitis E virus genome in pig livers in Antioquia, Colombia
Authors: C. Guti�©rrez-Vergara, J. Quintero, J.F. Duarte, J.P. Suesc�ºn and A. L�³pez-Herrera
Hepatitis E is a form of endemic acute hepatitis found in humans in many countries worldwide and is caused by the hepatitis E Virus (HEV). Detection of HEV in pigs indicates that they may be carriers, possibly through zoonosis. The prevalence of HEV in pigs in Colombia is unknown. Studies in the US found that 11% of pig livers..

Association between male infertility and androgen receptor mutations in Brazilian patients
Authors: C.O.A. Melo, A.R. Danin, D.M. Silva, J.A. Tacon, K.K.V.O. Moura, E.O.A. Costa and A.D. da Cruz
The androgen receptor is encoded by a single-copy gene located in the long arm of the X chromosome (Xq11-12); it consists of eight exons and encodes an intracellular transcription factor that belongs to the steroid/nuclear receptor superfamily. Disturbances in the function of the androgen receptor can lead to several forms of .. Read More»

Characterization of a novel Cry8Ea3-binding V-ATPase Subunit A in Holotrichia parallela
Authors: W. Wei, G. Wei, Z. Dan1, Y. Xiaoping and Z. Yakun
Several receptor proteins of Cry toxin have been previously identified, including cadherin-like, aminopeptidase N, and alkaline phosphatase. In the present work, a novel binding protein, V-ATPase subunit A (HpVAA), was identified in Holotricia parallela larvae and characterized. We performed reverse transcription-polymerase ch..

Mutagenic influences of colchicine on phenological and molecular diversity of Calendula officinalis L.
Authors: Y.I. El-Nashar and M.H. Ammar
Six different colchicine concentrations: 0, 400, 800, 1200, 1600, and 2000 ppm, in combination with four soaking time treatments (1, 2, 3, and 4 h), were selected to assess the effects on germination, vegetative growth, and flower yield components in calendula plants. The molecular diversity among the treatments was assessed u.. Read More»

Molecular phylogeny and biotechnological potential of bacterial endophytes associated with Malpighia emarginata
Authors: V. Specian, A.T. Costa, A.C. Felber, J.C. Polonio, J.L. Azevedo and J.A. Pamphile
Acerola (Malpighia emarginata) is a shrub native to tropical and subtropical climates, which has great commercial interest due to the high vitamin C content of its fruit. However, there are no reports of the endophytic community of this plant species. The aim of this study was to verify the genetic diversity of the leaf endoph.. Read More»

Development and characterization of new microsatellites for Eugenia dysenterica DC (Myrtaceae)
Authors: M.P.C. Telles, J.B. Silva, L.V. Resende, R.P. Vianello, L.J. Chaves, T.N. Soares and R.G. Collevatti
Microsatellite markers were developed for population genetic analyses of the Neotropical tree Eugenia dysenterica DC (Myrtaceae), after construction of a shotgun genomic library for microsatellite discovery. Nine primers were designed, of which 5 yielded amplified product. These primers were polymorphic for 97 individuals collected in 3 distinct localitie.. Read More»

Growth factor progranulin blocks tumor necrosis factor-�±-mediated inhibition of osteoblast differentiation
Authors: N. Wang, J. Zhang and J.X. Yang
Tumor necrosis factor-a (TNF-a) stimulates osteoclast differentiation and suppresses osteoblast differentiation, leading to bone loss and decreased bone mass in local inflammation areas in patients with rheumatoid arthritis. The growth factor progranulin (PGRN) is expressed in various types of cells and play crucial roles in t.. Read More»

Association of the IL-4R Q576R polymorphism and asthma in the Chinese Han population: A meta-analysis
Authors: Z.Y. Huang, B.J. Cheng, G.J. Cai and B.F. Zhang
The IL-4R Q576R polymorphism has been reported to increase susceptibility to asthma, but the results are controversial. Thus, we performed a meta-analysis to evaluate the association of the IL-4R Q576R polymorphism and asthma risk in the Chinese Han population. A total of sixteen eligible case-control studies that evaluated th.. Read More»

Somatic cell nuclear transfer is associated with altered expression of angiogenic factor systems in bovine placentomes at term
Authors: D.B. Campos, P.C. Papa, J.E.B. Marques Jr., F. Garbelotti, L.A. F�¡tima, L.P. Artoni, E.H. Birgel Jr., F.V. Meirelles, J. Buratini Jr., R. Leiser and C. Pfarrer
Low efficiency of somatic cell cloning by nuclear transfer has been associated with alterations of placental vascular architecture. Placental growth and function depend on the growth of blood vessels; VEGF-A and bFGF are the most important factors controlling neovascularization and vascular permeability in the placenta. We hyp..
