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..

Clinical features of Mexican patients with Mucopolysaccharidosis type I
Authors: A. Alonzo-Rojo, J.E. GarcÃ?Âa-Ortiz, M. Ortiz-Aranda, M.P. Gallegos-Arreola and L.E. Figuera-Villanueva
Mucopolysaccharidosis type I (MPS-I) is an autosomal recessive lysosomal storage disorder caused by a deficiency or absence of α-l-iduronidase, which is involved in the catabolism of glycosaminoglycans (GAGs). This deficiency leads to the accumulation of GAGs in several organs. Given the wide spectrum of the disease, MPS.. Read More»
