1. Nassarius foveolatus (Gastropoda, Nassariidae), a new record of an exotic species in Brazil
Abstract Exotic species are those that occur in an area beyond their natural limit and they are considered invasive when they cause harm to the economy, environment, or human health. In coastal environments, ballast water and inlays on the hull and other parts of vessels are the main ways of introducing invasive aquatic alien species. Nassarius foveolatus (D

2. Molecular detection of Bartonella, Ehrlichia and Mycoplasma in feral dogs of El Pedregal de San Angel Ecological Reserve in Mexico City
Resumo Cães errantes e selvagens representam um grupo de animais de companhia livres. Eles impactam as populações de animais selvagens pela predação de espécies nativas, deslocando predadores e introduzindo patógenos exóticos. O objetivo deste trabalho foi descrever a ocorrência molecular de Rickettsia, Ehrlichia, Anaplasma, Mycoplasma e Bartonella

3. Malaria in Brazil: what happens outside the Amazonian endemic region
Brazil, a country of continental proportions, presents three profiles of malaria transmission. The first and most important numerically, occurs inside the Amazon. The Amazon accounts for approximately 60% of the nation’s territory and approximately 13% of the Brazilian population. This region hosts 99.5% of the nation’s malaria cases, which are predomina

4. Species with medicinal and mystical-religious uses in São Francisco do Conde, Bahia, Brazil: a contribution to the selection of species for introduction into the local Unified Health System
We investigated the knowledge and practices of local residents in São Francisco do Conde, Bahia, regarding the use of medicinal and mystical plants with the aim of proposing strategies for the incorporation of phytotherapies into the local Unified Health System through local Basic Health Clinics. This municipality was founded during the early colonization o

5. Cytogenetic identification of wheat-Psathyrostachys huashanica amphiploid × triticale progenies for English grain aphid resistance
English grain aphid (EGA, Sitobion avenae Fabricius) is an important pest in wheat (Triticum aestivum L.). To develop EGA-resistant varieties, introducing the desirable genes from related species is regarded as an efficient avenue. In this study, the F1, F2 and F3 plants derived from the cross of EGA-susceptible wheat-Psathyrostachys huashanica Keng ex Kuo a

6. The influence of behavioral enrichment on dry food consumption by the black tufted-ear marmoset, Callithrix penicillata (Mammalia: Callithricidae): a pilot study
Stereotyped behaviors in captive primates are often caused by unsuitable conditions. Environmental enrichment has been used to reduce these behaviors, and also to increase the frequency of behaviors appropriate to the species. In this pilot study we evaluated whether behavioral enrichment influences food intake by the black tufted-ear marmoset, Callithrix pe

7. A influência de uma espécie exótica invasora, Artocarpus heterophyllus Lam. (jaqueira), sobre uma comunidade de pequenos mamíferos e sua interferência na dinâmica de dispersão de sementes nativas / The influence of an invasive alien species, Artocarpus heterophyllus Lamk. (jack fruit), about a community of small mammals and their influence on the dynamics of dispersal of native seeds
Atualmente, sabe-se que danos causados por espécies exóticas invasoras são umas das principais causas de extinção de espécies, afetando mais seriamente espécies que evoluíram em ilhas. A jaqueira, Artocarpus heterophyllus Lamarck (Moraceae) é originária das florestas tropicais da Índia. Foi introduzida no Brasil ainda no período Colonial e atualm

8. Hybridism between Biomphalaria cousini and Biomphalaria amazonica and its susceptibility to Schistosoma mansoni
Molecular techniques can aid in the classification of Biomphalaria species because morphological differentiation between these species is difficult. Previous studies using phylogeny, morphological and molecular taxonomy showed that some populations studied were Biomphalaria cousini instead of Biomphalaria amazonica. Three different molecular profiles were ob

10. Aspectos da introdução das espécies exóticas: o capim-gordura e a braquiária no Parque Nacional de Brasília
Invasive alien species are the major biological threats to the environment, with huge losses to the economy, to the biodiversity and natural ecosystems, an also provides risks to human health. They are considered the second leading cause of biodiversity loss. Currently underway is acceleration in the process of biological invasions and National Park of Brasi

11. Clinical relevance of oxidative stress and sperm chromatin damage in male infertility: an evidence based analysis
Oxidative stress (OS) in the reproductive tract is now a real entity and concern due to the potential harmful effects of high levels of reactive oxygen species (ROS) on sperm number, motility, quality, and function including damage to sperm nuclear DNA. Evaluation of OS related damage to non-functional sperm is highly relevant as intracytoplasmic sperm injec

12. Chagas disease in the Amazon Region
The risk that Chagas disease becomes established as a major endemic threat in Amazonia (the world's largest tropical biome, today inhabited by over 30 million people) relates to a complex set of interacting biological and social determinants. These include intense immigration from endemic areas (possibly introducing parasites and vectors), extensive landscap
