1. Detection, purification and characterization of a lectin from freshwater green algae Spirogyra spp.
ABSTRACT Freshwater algae are rich sources of structurally biologically active metabolites, such as fatty acids, steroids, carotenoids and polysaccharides. Among these metabolites, lectins stand out. Lectins are proteins or glycoproteins of non-immune origin which bind to carbohydrates or glycoconjugates, without changing ligand structure. Many studies have

2. Investigação dos polimorfismos dos genes da interleucina-1 (IL-1), IL1RN, IL-4, IL-6 e IL-10 em pacientes adultos portadores de púrpura trombocitopênica imune = : Investigation of interleukin-1 (IL-1), IL1RN, IL-4, IL-6 and IL-10 gene polymorphism adult patients with immune thrombocytopenic purpura / Investigation of interleukin-1 (IL-1), IL1RN, IL-4, IL-6 and IL-10 gene polymorphism adult patients with immune thrombocytopenic purpura
The immune thrombocytopenic purpura (ITP) is an autoimmune disease characterized by the presence of autoantibodies against the platelet membrane glycoproteins such as GPIIb/IIIa and GPIb/IX. The pathogenic process of ITP involves an accelerated destruction of platelets by reticuloendothelial system and the presence of mucocutaneous bleeding. The inflammatory

3. Infecção pelo Paracoccidioides brasiliensis em população de assentamentos rurais de Jaraguari, Mato Grosso do Sul. Estudo epidemiológico utilizando a intradermorreação com gp43 e retestagem para avaliação do fenômeno booster.
Estudos sobre a epidemiologia da infecção paracoccidióidica são baseados em inquéritos realizados com testes intradérmicos, sendo a paracoccidioidina o antígeno mais utilizado, contudo, reações cruzadas com outras infecções fúngicas têm sido relatadas. A glicoproteína de 43 - kDa (gp43) por ser o componente mais antigênico do Paracoccidioides

4. Evaluation of Caesalpinia pulcherrima endospermic gum as affinity matrices for galactose-binding lectins interaction
Lectins are proteins or glycoproteins able to bind, specifically and reversibly carbohydrates and glycoconjugates. Considering this ability, the utilization of Caesalpinia pulcherrima seeds polysaccharides as an affinity matrix was tested. The endospermic gum were solubilized in distinct concentrations of NaOH and treated with different amounts of epichloroh

5. Reatividade de anticorpos a frações antigênicas de Strongyloides venezuelensis no diagnóstico diferencial da estrongiloidíase humana
Strongyloides stercoralis, nematódeo parasita intestinal, é um dos responsáveis pelas infecções parasitárias mais prevalentes em humanos. A detecção precoce previne o desenvolvimento das síndromes clínicas de hiperinfecção e disseminação. Na procura por marcadores de resposta imune na estrongiloidíase, as propriedades antigênicas de component

6. Avaliação das respostas imunológicas e protetora de uma vacina de DNA contra tumores induzidos por HPV-16. / Immune responses and anti-tumor therapeutic effects generated by a DNA vaccine against HPV-16-induced tumors.
No presente trabalho, desenvolvemos uma estratégia vacinal baseada em vacinas de DNA que codificam proteínas do HPV-16, o tipo viral de maior relevância epidemiológica, fusionadas à glicoproteína D (gD) do vírus herpes simplex tipo 1 (HSV-1). A vacina que contêm o gene da E7 de HPV-16 fusionada à gD de HSV-1 (pgDE7), administrada em regime vacinal d

7. CaracterizaÃÃo BioquÃmica Parcial do LÃtex de Cryptostegia grandiflora R. Br. e AÃÃo Contra o Vetor da Dengue. / Biochemical characterization of latex of Cryptostegia grandiflora and larvicidal activity against Aedes aegypti
Cryptostegia grandiflora R. Br. is a shurb belonging to Apocynaceae family popularly known as âunha de bruxaâ. There are few studies available about the latex from this species and preliminary assays had shown its action against Dengue vector. Thus, this study aimed to characterize the biochemical properties of Cr. grandiflora latex and to evaluate the act

8. Montagem de um pseudo-hantavírus quimera, contendo a nucleoproteína do vírus Araraquara e as glicoproteínas do vírus Andes, em sistema baculovírus / Assembly of a chimeric hantavirus-like particle, containing the Araraquara nucleoprotein and the Andes glycoproteins, expressed in baculovirus system
Hantaviruses, members of the Bunyaviridae family, are the infectious agents responsible for Hemorrhagic Fever with Renal Syndrome and the Hantavirus Cardiopulmonary Syndrome. The viral genome is composed by three segments of single-stranded negative-sense RNA, designated as S, M and L, which encode, respectively, the nucleoprotein, the G1 and G2 glycoprotein

9. Construção e análise das propriedades profiláticas e terapêuticas de uma vacina contra tumores associados ao HPV-16. / Construction and analysis of the prophylactic and therapeutic proprieties of a vaccine against HPV-16 associated tumors.
The development of vaccines against human papillomavirus (HPV) represents an important alternative to control the sexually transmitted infection and cervical cancer. In this paper we explored a novel vaccine strategy against tumors induced by HPV-16 using the E7 protein obtained after genetic fusion to the glycoprotein D of herpes virus type 1, a protein wit
