13. Caracterização do parasitismo por Ornithodoros brasiliensis (Chelicerata: Argasidae) e da toxicose induzida em humanos e animais
Ticks are blood-sucking arthropods distributed worldwide and able to parasitize almost all terrestrial vertebrate animals. Ticks are considered a great hazard for both public health and animal breeding due to their ability to transmit infectious diseases and to induce direct toxic effects leading to clinical disturbances. Ornithodoros brasiliensis, popularly

14. A new specie of Artigasia Christie, 1934 (Oxyurida: Hystrignathidae) from a Cuban passalid beetle
Artigasia milerai sp. nov. (Oxyurida: Hystrignathidae) is described from the gut caeca of Passalus interstitialis Escholtz, 1829 (Coleoptera: Passalidae) from Escaleras de Jaruco, La Habana province, Cuba (type locality) and El Pan de Matanzas, Matanzas province, Cuba. It differs from A. ensicrinata (Hunt, 1981), A. monodelpha (Travassos & Kloss, 1958) and A

15. Estudo da interação do As(III) com modelo "zinc finger" da proteína NCp7 HIV-1 e complexos de Bi(III) e Sb(III) com ligantes contendo 2-mercapto-imidazol
The ejection of zinc from its coordination site in Zn-finger protein can be promoted by other metal species through competitive binding. This is considered as a promising strategy to inactivate the Zn-finger protein and for the design of new and more efficient drugs. A study of the As(III) interaction with the CCHC zinc finger domain of the NCp7 protein of H

16. Avaliação do modelo de hamster para detecção das alterações lipídicas e cardiotoxicidade associadas à terapia contra o vírus da imunodeficiência humana / Evaluation of the hamster model for the detection of lipidic and cardiotoxicity alterations associated to therapy against human immunodeficiency virus
With the introduction of a new antiretroviral class use, integrants of highly active anti-retroviral therapy (HAART) for the treatment of infections by human immunodeficiency virus, several side effects started to be described.To establish an animal model for the study of these side effects, was chosen specie that have similarities in the lipidic profile and

17. ATIVIDADE LEISHMANICIDA DE DERIVADOS AMINOQUINOLINICOS E EFEITO IMUNOMODULATÓRIO EM MACRÓFAGOS PERITONEAIS INFECTADOS COM LEISHMANIA AMAZONENSIS E L. MAJOR
The leishmaniasis are parasitic-infection diseases that affect 12 million people in 88 countries, it remains a serious public health problem worldwide, including in Brazil. This disease is caused by different Leishmania species, which invade and multiply within macrophages in vertebrate host. No vaccine exists yet and chemotherapy has been based mainly in pe

18. Pesquisa de genes de resistência a antimicrobianos beta-lactâmicos e de enterotoxina em cepas de Staphylococcus aureus presentes em amostras de alimentos / Search of antimicrobial beta-lactam resistance genes and enterotoxin genes in Staphylococcus aureus strains present in food samples
Introduction: Staphylococcus aureus are a bacterium that causes various types of diseases. There are two major aggravating to its presence: the toxins production and antimicrobial resistance. S. aureus produce heat-labile enterotoxina that, when present in food, can lead to poisoning of those who consume. This specie is also known to easily respond adaptivel

19. Atividade de constituintes micromoleculares de Renealmia alpinia (Rottb.) Maas (Zingiberaceae) sobre Leishmania (Leishmania) chagasi
Leishmaniasis is a complex of tropical disease caused by protozoa belonging to the genus Leishmania and it is among the six most important endemic diseases in the world. Its clinical manifestations can vary from benign cutaneous injuries to the disfiguring and destructive mucosal lesions or to the visceral form, fatal if not treated. Its incidence has increa

20. Taxonomia de Philosepedon Eaton, 1904 (Diptera, Psychodidae, Psychodinae) no Brasil
The genus Philosepedon Eaton, 1904 was proposed to Psychoda humeralis Meigen, 1818 by monotype. The taxonomic position of Philosepedon in Psychodinae and its diagnose are controversial. Here, it is proposed a new diagnose to genus. The objective of this study was study the Brazilian fauna of Philosepedon, a genus poor studied in this country. 185 specimens w

21. Seleção de novos tipos e propagação rápida em Solenostemon scutellarioides, Lamiaceae / Selection of new tipes and rapid propagation in Solenostemon Scutellarioides, Lamiaceae
The specie Solenostemon scutellarioides is an ornamental plant cultivated since the era Victoriana, very used due to great diversity of coloration, format of leaves and growth habits. However, the great instability of coloration and formats of these varieties have been hindering its commercial exploration. Two assays were conducted in the Experimental Statio

Microsatellite molecular markers are small repeated sequences in tanden compound of 1 to 6 nucleotides. Widely used as genetic markers, the microsatellites have a particular attribute that is the high rates of mutation. These molecular markers or are widely used in conservation genetics, population genetics, forensic research, diagnosis of diseases, ecologic

23. Análise estatística do efeito da pressão na carbonização da madeira de Eucaliptus grandis
Brazil is the largest producer and consumer of charcoal with 75% for the steel industry. Carbonization processes are usually difficult to control craft technologies and offering relatively low mass yields. The average values are often admitted between 18 and 25%. New technologies are being developed to improve these numbers. Pyrolysis under pressure is one s

24. Characterization of chitinase gene from lutzomyia longipalpis:alternative splicing description and search for promoter sequence / Caracterização de gene de quitinase de Lutzomyia longipalpis: descrição de processamento alternativo e busca por seqüência promotora
Leishmaniasis is a disease caused by Leishmania protozoa transmitted by the bite of infected sand flies. Current methods used to combat this illness have been shown to be inefficient, and better knowledge of aspects related to Leishmania-sand fly interaction are necessary for the development of new controlling methods.
