13. GLUT1 expression in malignant tumors and its use as an immunodiagnostic marker
OBJECTIVE: To analyze glucose transporter 1 expression patterns in malignant tumors of various cell types and evaluate their diagnostic value by immunohistochemistry. INTRODUCTION: Glucose is the major source of energy for cells, and glucose transporter 1 is the most common glucose transporter in humans. Glucose transporter 1 is aberrantly expressed in sever

14. Seropositivity rates for toxoplasmosis, rubella, syphilis, cytomegalovirus, hepatitis and HIV among pregnant women receiving care at a public health service, São Paulo state, Brazil
Infectious and parasitic diseases affecting women during their reproductive age may result in vertical transmission. The aim of this study was to determine the seroprevalence for TORSCH among pregnant women receiving care at a university hospital. Records of 574 pregnant women who received medical attention from January 2006 to December 2007 were assessed. T

15. Use of heterologous antigens for the immunodiagnosis of abdominal angiostrongyliasis by an enzyme-linked immunosorbent assay
Angiostrongylus costaricensis has a broad geographic distribution spanning from North to South America and the infections of vertebrates with this nematode can result in abdominal complications. Human infections are diagnosed by histological or serological methods because the isolation of larvae from feces is not feasible, as most parasites become trapped in

16. Determination of the association of urine prostate specific antigen levels with anthropometric variables in children aged 5-14 years
PURPOSE: Calculation of PSA is possible in human fluids even if it presents in very low concentrations with the help of hypersensitive immunodiagnostic methods. The periurethral glands represent one of the potential sources of urine prostate specific antigen (uPSA) in both sexes but the purpose of studying PSA levels in children is still unclear in the liter

17. Anti-Toxoplasma gondii secretory IgA in tears of patients with ocular toxoplasmosis: immunodiagnostic validation by ELISA
Toxoplasma gondii causes posterior uveitis and the specific diagnosis is based on clinical criteria. The presence of anti-T. gondii secretory IgA (sIgA) antibodies in patients' tears has been reported and an association was found between ocular toxoplasmosis and the anti-T. gondii sIgA isotype in Brazilian patients. The purpose of this study was to provide a

18. Seleção de peptídeos reconhecidos por imunoglobulinas Y anti-metacestódeo de Taenia solium por phage display
The Taenia solium metacestodes localization in humans occours mainly in the central nervous system (CNS) promoting the disease named neurocysticercosis (NC), the most frequent parasitosis in the CNS. The pathological presentation of NC differs about localization and viability of metacestodes, and host immunological response. For its diagnosis stabelishment i

19. Epitope mapping and secondary struture characterization of Citrus tristeza virus coat protein and immunomolecular diagnosis to Xystella fastidiosa / Caracterização dos epitopos e da estrutura secundaria da proteina do capsideo do Citrus tristeza virus e um diagnostico imunomolecular para Xystella fastidiosa
Este trabalho visou efetuar a identificação dos epitopos das prottnas recombinantes CB-22 e CB-104 do capsídeo do Cítrus tristeza vírus (CTV), reconhecidos pelos anticorpos monoclonais (MAb) produzidos por Stach-Machado e colaboradores (2000). Assim, os epitopos reconhecidos pelos MAbs 30.G.02 e 37.G.ll, correspondem às seqüências de aminoácidos NLH

20. CARACTERIZAÇÃO ESTRUTURAL E IMUNOQUÍMICA DE GLICOINOSITOL FOSFORILCERAMIDAS DE Aspergillus fumigatus. EFEITO DE INIBIDORES DE SÍNTESE DE GLICOESFINGOLIPÍDEOS EM FUNGOS PATOGÊNICOS. / Structural and immunochemical characterization of glycosylinositol phosphorylceramides from Aspergillus fumigatus. Effect of glycosphingolipid synthesis inhibitors on pathogenic fungi.
The search for alternatives for new antifungal therapies led our laboratory to analyze the molecular structures of specific glycosphingolipids (GSLs) present in fungi but not in mammals. We analyze the molecular structures of glycosylinositol phosphorylceramides (GIPCs) from the opportunistic fungus Aspergillus fumigatus. GSLs were extracted and purified by

21. Use of the paired samples (cerebrospinal fluid and serum) in immunodiagnostic of active and inactive human neurocysticercosis
Paired samples of cerebrospinal fluid (CSF) and serum of 30 patients - 10 with active, 10 with inactive neurocysticercosis (NCC), and 10 control subjects - were evaluated by enzyme-linked immunosorbent assay (ELISA) using two Taenia crassiceps metacestode extracts as antigen in order to detect IgG antibodies. In active NCC, high levels of IgG were detected (

22. Desenvolvimento de um método sorológico para o diagnóstico laboratorial da esquistossomose mansoni baseado em peptídeos sintéticos / Development of a serologic method for laboratory diagnosis of the schistosomiasis mansoni based on synthetic peptides
Based on algorithms of hidrophilicity and flexibility, obtained by the use of the ProtScale software, disposable at the site http://au.expasy.org/cgi-bin/protscale.pl, seven potentially antigenic peptides were selected from different Schistosoma mansoni proteins: cathepsin B (Sm31), heat shock protein (SmHSP-70), cathodic circulating antigen (CCA) and the po

23. Diagnosis of American trypanosomiasis (Chagas' disease) by the new complement fixation test.
A new immunodiagnostic method of complement fixation was used for serodiagnosis of American trypanosomiasis; 92% sensitivity and 99% specificity were obtained, for an overall accuracy of 97%. This test can be used in field studies, obviating the use of most laboratory equipment and imported reagents; places where economic limitations hinder the use of other

24. Evaluation of an automated immunodiagnostic assay system for direct detection of herpes simplex virus antigen in clinical specimens.
The Vitek ImmunoDiagnostic Assay System (VIDAS) is a 2 1/3-h automated qualitative enzyme-linked fluorescent immunoassay developed for the direct detection of herpes simplex virus (HSV) antigen in clinical specimens. A total of 356 clinical specimens submitted for HSV isolation were prospectively evaluated with the VIDAS, and the results of the technique wer
