The book Funções do cérebro (Workings of the brain), by physician Domingos Guedes Cabral, is recognized as one of the first Brazilian works to defend Darwinist theories. In light of the need for more studies on the reception of evolutionism in Brazil, the article investigates this book in an effort to reveal how Guedes Cabral used evolutionism in his argumentation and to reveal the purpose of his arguments within a historical context. Findings indicate that Guedes Cabral relied on evolutionism as part of both an ideological project and an incipient eugenic theory, later developed in the early twentieth century.

Six males of Phyllocycla hamata Belle, 1990 were collected in the Reserva Florestal da Usina Hidroelétrica Jauru, Salto da Fumaça, Mato Grosso state, Midwestern Brazil and represent the first record for that state. The specimens examined have been deposited in the Museu Nacional, UFRJ, Rio de Janeiro, RJ, Brazil. This species is included in the volsella group and can be separated from the other species in this group by the cerci shorter than segment 10 (S10), with a very long internal hook. © 2011 Check List and Authors.

The molecular epidemiology of Ascaris spp. of human and pig origin has been studied as a means to assess the potential of pigs as reservoirs for human ascariasis. In this study, human (H) and pig (P) Ascaris spp. haplotypes from two Brazilian regions were characterised based on two mitochondrial genes, nad1 and cox1. The results show six haplotypes of the cox1 gene, with two haplotypes (H9P9 and P3) corresponding to haplotypes previously characterised in China. Because P3 was found in humans in this study, it was designated as H14P3. Furthermore, five new Ascaris spp. nad1 haplotypes from humans (H12- H16) and five from pigs (P16- P20) were observed, with one being highly frequent and present in both hosts, here designated as H12P17. Phylogenetic and network analysis demonstrated that the molecular epidemiology of Ascaris spp. in Brazil is driven by the globally distributed haplotypes cox1 H14P3 and nad1 H12P17. In conclusion, in this study genetic characterisation of Ascaris spp. showed that humans and pigs share common haplotypes that are also present in two widely separated geographical regions of Brazil. © 2012 Royal Society of Tropical Medicine and Hygiene.

The common use of Pouteria mammosa (L.) Cronquist, "Mamey or Zapote," in food and ethnobotanic medicine shows its low or absent toxicity as fruit extracts prepared from seeds. However, it is essential to conduct security trials to scientifically support their use in drug therapy. This study evaluated the aqueous and hydroalcoholic extract (25%) Acute Oral Toxicity, obtained from the seeds of P. mammosa, in Sprague Dawley rats and dermal and eye irritability in New Zealand rabbits. The 404 and 405 acute dermal and eye irritation/corrosion guidelines were used, as well as the 423 Acute Oral Toxicity guideline, Acute Toxic Class Method of the Organization for Economic Cooperation and Development (OECD). The aqueous extract was located in the following category: not classified as toxic (CTA 5), while hydroalcoholic extract at 25% was classified as dangerous (CTA 4). Both extracts can be used without side reaction that irritates the skin which permitted classification as potentially not irritant. P. mammosa in the two extracts caused mild and reversible eye irritation, and it was classified as slightly irritating. © 2015 Carlos M. S. Dutok et al.
