25. The study of ionizing radiation as a tool for select promastigotes forms of Leishmania amazonensis, and the immunological response in experimental models / Estudo do uso da radiação ionizante como ferramenta de seleção de formas promastigotas metacíclicas de Leishmania amazonensis e a indução de resposta imunológica em modelos experimentais
Actually, millions of people around the globe are under the risk of infection by a protozoan transmitted by a bit of a sand fly. This parasite is a Leishmania spp. This causes a wide spectrum disease, since a coetaneous disease to a visceral one. The coetaneous form is the major clinical manifestation (above 90%). The ionizing radiation, produced in a 60Co f

26. Estudo dos componentes nutricionais e imunológicos na perda de peso em camundongos com alergia alimentar
Allergic diseases have reached epidemic proportions and are characterized by IgE production against antigens that gain the organisms through the mucosas. Here, we used a allergy model which BALB/c mice receive ovalbumin orally after sensitization with ovalbumin. After the oral challenge with egg white solution, the ovalbumin sensitized BALB/c mice usually sh

27. Immunological assessment of mice hyperimmunized with native and Cobalt-60-irradiated Bothrops venoms
ELISA was used to evaluate, accompany, and compare the humoral immune response of Swiss mice during hyperimmunization with native and Cobalt-60-irradiated (60Co) venoms of Bothrops jararaca, Bothrops jararacussu and Bothrops moojeni. Potency and neutralization were evaluated by in vitro challenges. After hyperimmunization, immunity was observed by in vivo ch

28. Fatores que interferem na reação imune cruzada entre phytomonas serpens e trypanosoma cruzi
The immune cross-reaction between Trypanosoma cruzi, the etiological agent of Chagas´ disease and Phytomonas serpens, a trypanosomatid parasite of tomatoes can be used for diagnostic and protective purposes in experimental murine models. Phytomonas serpens is available in various strains, cultivated from infected tomato fruits at various times and places, a

29. WORKFLOW PARA BIOINFORMÁTICA / WORKFLOW FOR BIOINFORMATICS
Genome projects usually start with a sequencing phase, where experimental data, usually DNA sequences, is generated, without any biological interpretation. DNA sequences have codes which are responsible for the production of protein and RNA sequences, while protein sequences participate in all biological phenomena, such as cell replication, energy production

30. Cationic bilayers over silica: adsorption and colloidal stability at low ionic strength / Bicamadas catiônicas em sílica: adsorção e estabilidade coloidal a baixa força iônica
The study of adsorption of model-membranes on the surface of solid partic1es is an important line of research in rapidly developing research areas such as biosensors design, building up of immunological kits or design ofbiocompatible materiais. In this work, interactions between hidrophilic silica particles and cationic liposomes made up of dioctadecyldimeth

31. HIV-1 Polymorphism: a Challenge for Vaccine Development - A Review
The perspective for the development of anti-HIV/AIDS vaccines became a target sought by several research groups and pharmaceutical companies. However, the complex virus biology in addition to a striking genetic variability and the limited understanding of the immunological correlates of protection have made this an enormous scientific challenge not overcome

32. Natural immunoglobulins (contribution to a debate on biomedical education)
Immunology has contributed to biomedical education in many important ways since the creation of scientific medicine in the last quarter of the 19th century. Today, immunology is a major area of biomedical research. Nevertheless, there are many basic problems unresolved in immunological activities and phenomena. Solving these problems is probably necessary to

33. Immunological Unresponsiveness Induced by Cryptococcal Capsular Polysaccharide Assayed by the Hemolytic Plaque Technique
Numerous studies have suggested that cryptococcal capsular polysaccharide could induce an immunological paralysis. To investigate this possibility, mice were given various concentrations of purified cryptococcal polysaccharide and then 14 days later were challenge-immunized with the same material in Freund's incomplete adjuvant. Anticryptococcal agglutinin t

34. Host Defenses in Murine Malaria: Immunological Characteristics of a Protracted State of Immunity to Plasmodium yoelii
Random-bred ICR mice recovered from infection with avirulent Plasmodium yoelii were challenged at various later times with virulent P. yoelii or with another species of Plasmodium, P. berghei, to characterize the immunological nature of the long-term state of immunity generated in response to the avirulent infection. It was found that recovered mice resisted

35. Persistence of Pathogenic Challenge Virus in Macaques Protected by Simian Immunodeficiency Virus SIVmacΔnef
Live attenuated simian immunodeficiency virus (SIV) is the most efficient vaccine yet developed in monkey models of human immunodeficiency virus infection. In all successful vaccine trials, attenuation was achieved by inactivating at least the nef gene. We investigated some virological and immunological characteristics of five rhesus macaques immunized with
