1. Trichomonas vaginalis and associated factors among women living with HIV/AIDS in Amazonas, Brazil
OBJECTIVES: Our goal was to determine the prevalence of Trichomonas vaginalis and its associated factors among women living with HIV attending an AIDS clinic in Manaus, Amazonas, Brazil. METHODS: Cross-sectional study among women attending an AIDS clinic in Manaus between March and December 2010 for gynecological examination were invited to participate. Enro

2. Glucocorticoid-induced tumor necrosis factor receptor expression in patients with cervical human papillomavirus infection
Introduction The progression of human papillomavirus (HPV) infection in the anogenital tract has been associated with the involvement of cells with regulatory properties. Evidence has shown that glucocorticoid-induced tumor necrosis factor receptor (GITR) is an important surface molecule for the characterization of these cells and proposes that GITR ligand

3. Induction of cell migration and activation in mice by the freshwater sponge Drulia uruguayensis Bonetto & Ezcurra de Drago, 1968 (Porifera: Metaniidae)
Freshwater sponges are abundant in the Amazon region and they have been known to cause dermatitis (acute inflammation) since the beginning of the 20th century. To determine whether additional constituents, besides their body spicules, cause dermatological reactions in humans, an experimental study was developed and carried out using mice and Drulia uruguayen

4. Local lymphocytes and nitric oxide synthase in the uterine cervical stroma of patients with grade III cervical intraepithelial neoplasia
OBJECTIVES: Precancerous and cancerous cells can trigger an immune response that may limit tumor development and can be used as a prognostic marker. The aims of the present study were to quantify the presence of B and T lymphocytes, macrophages and cells expressing inducible nitric oxide synthase (iNOS) in the cervical stroma of women with grade III cervical

5. Avaliação da granzima B e do fator de crescimento endotelial vascular em pacientes com neoplasia intra-epitelial escamosa cervical de baixo e de alto grau / Immunohistochemical expression of granzyma B and vascular endothelial growth factor (VEGF) in normal uterine cervix, low and high grade squamous intraepithelial lesions
Introduction: The granzyme family designates a special group of serinoproteases which are stored fully processed and in the active form in cytoplasmic granules of the cytolytic T lymphocytes cells (CTL). Angiogenesis is the process in which new blood vessels are formed. It is associated with development of high degree intraepithelial neoplasia and invasive c

6. Human adenovírus serotype 41 interaction with hematopoietic cells: cellular permissiviness and viral gene expression analysis. / Interação do adenovírus humano, sorotipo 41, com células origem hematopoiética: análise da permissividade celular e da expressão gênica viral.
In order to verify the permissiveness of hematopoietic cells to HAdV-41 infection, PBMC and IEL from volunteers were infected. The infection assays were compared with infected HEK -293 cells. We analysed the E1A, E1B (55K), E3 (14K), VARNA, hexon and short fiber (SF) viral gene expression and GAPDH cellular gene expression. The mRNA were detected by real tim

7. Estudo da resposta imune e do tipo de papiloma vírus humano na evolução de pacientes conizadas por neoplasia intra-epitelial cervical grau III.
Uterine cervix cancer remains the third most common neoplasia and the fourth cause of death due to cancer among Brazilian women, althougth a decreasin incidence, morbidity and mortality have been observed over the last decades. Human papillomavirus (HPV) has been indicated as its most important causal factor. The local and systemic host immune response seem

8. Avaliação da imuno-expressão da granzima B na neoplasia intra-epitelial cervical em mulheres infectadas pelo HIV / Evaluation of Granzyme B expression in cervical intraepithelial neoplasia from HIV infected women
Granzyme B is a serine protease synthesized in activated cytotoxic T lymphocyte after exogenous stimulation. Cytotoxic T lymphocyte are the main effector in eradication process of neoplasic cell and virus infected cell. With perforin, granzyme B discharge apoptosis signal to a target cell. The objective of this study was to evaluate granzyme B expression in

9. Immunopathology of giardiasis: the role of lymphocytes in intestinal epithelial injury and malfunction
T lymphocyte-mediated pathogenesis is common to a variety of enteropathies, including giardiasis, cryptosporidiosis, bacterial enteritis, celiac's disease, food anaphylaxis, and Crohn's disease. In giardiasis as well as in these other disorders, a diffuse loss of microvillous brush border, combined or not with villus atrophy, is responsible for disaccharidas

10. Activation of intestinal intraepithelial T lymphocytes in calves infected with Cryptosporidium parvum.
The objective of this study was to identify disease-related changes in lymphocyte populations within ileal mucosae of calves with cryptosporidiosis. Groups of five neonatal calves were orally infected at 3 days of age with 10(8) oocysts and maintained in enteric-pathogen-free conditions until clinical disease was established or until the animals had recovere

11. Cellular infiltrate of the jejunum after re-introduction of dietary gluten in children with treated coeliac disease.
Jejunal lamina propria plasma cells and eosinophils and intraepithelial lymphocytes were raised in coeliac children on gluten-containing diets, but only intraepithelial lymphocytes were increased in patients on gluten-free diets. In contrast, lamina propria lymphocytes were reduced in children with coeliad disease on gluten-containing diets but were normal i

12. Lymphocytic gastritis and coeliac disease: evidence of a positive association.
AIMS: To investigate the prevalence of lymphocytic gastritis in patients with coeliac disease. METHODS: Gastric biopsies from 70 patients with coeliac disease were examined by light microscopy for the presence of lymphocytic gastritis, defined as 25 or more intraepithelial lymphocytes/100 gastric columnar epithelial cells. RESULTS: Lymphocytic gastritis was
