Authors: L.C. Souza, A.L. Silva J�ºnior, M.C. Souza, S.H. Kunz and F.D. Miranda
Studies of genetic diversity in natural populations are important for the definition of conservation strategies, especially in populations reduced by processes of fragmentation and continuous forest extraction. Molecular markers stand out as interesting tools for these studies. The objective of this research was to characteriz.. Read More»

Genotypic variation and relationships among nitrogen-use efficiency and agronomic traits in tropical maize inbred lines
Authors: M.C. Rodrigues, W.M. Rezende, M.E.J. Silva, S.V. Faria, L.T. Zuffo, J.C.C. Galv�£o and R.O. DeLima
Improvement in nitrogen-use efficiency (NUE) on maize is among the best strategies to mitigate the problems of poor soil fertility in tropical conditions. The objectives of this study were: i) to quantify the genetic variability for NUE-components and agronomic traits in a set of tropical maize inbred lines; ii) to study the g.. Read More»

Contemporary pollen and seed dispersal in natural populations of Bertholletia excelsa (Bonpl.)
Authors: A.B. Baldoni, L.H.O. Wadt, T. Campos, V.S. Silva, V.C.R. Azevedo, L.R. Mata, A.A. Botin, N.O. Mendes, F.D. Tardin, H. Tonini, E.S.S. Hoogerheide and A.M. Sebbenn
Due to the nutritional content and commercial value of its seeds, Bertholletia excelsa is one of the most important species exploited in the Amazon region. The species is hermaphroditic, insect pollinated, and its seeds are dispersed by barochory and animals. Because the fruit set is dependent on natural pollinator activity, g.. Read More»

Interleukin-18 (rs187238) and glucose transporter 4 (rs5435) polymorphisms in Euro-Brazilians with type 1 diabetes
Authors: Y. Al-Lahham, A.K.B. Mendes, E.M. Souza, D. Alberton, F.G.M. Rego, G. Valdameri and G. Picheth
Type 1 diabetes (T1D) is an autoimmune disease with a strong genetic component that has been associated with several genetic loci. Interleukin 18 (IL-18) is a potent proinflammatory cytokine, which is involved in the innate and adaptive immune responses, and in the pathogenesis of various diseases including T1D. Glucose transp..

Authors: M. Wahid, S. Prasarnpun and N. Yimtragool
Cadmium (Cd) is produced mainly as a by-product of zinc mining. In Thailand, the largest zinc mine is located in the Mae Sot district, Tak Province. Samples of Monopterus albus were collected from paddy fields in 4 sites, three downstream and one upstream from the zinc mine. The upstream site was considered to be uncontaminate.. Read More»
