25. A microcirculação da bolsa da bochecha do hamster sob a influência do diabetes mellitus experimental induzido por estreptozotocina: aspectos morfofuncionais / Microcirculation of hamster cheek pouch under the influence of exerimental diabetes mellitus induced by streptozocin morpho-functional aspects
Diabetes Mellitus is a chronic metabolic disease with multiple etiologic factors (genetic, viral and immunological) that results in absolute or relative insulin deficiency, causing persistent elevated blood glucose levels. Nowadays, Diabetes Mellitus is considered as an important health concern due to its increasing prevalence and high morbimortality. Its cl

26. Estudo das proteínas da família gp82 das formas metacíclicas do Trypanosoma cruzi / Study of gp82 family proteins of Trypanosoma cruzi metacyclic forms
The main goal of this work was to characterize the proteins encoded by the gp82 gene fami ly, which is part of the large T. cruzi gp85/trans-sialidase multigenic family. Previous studies had focused on the surface gp82, which is engaged in the cell invasion by CL strain metacyclic forms and is identified by monoclonal antibody (MAb) 3F6. Firstly, we investig

27. Remodeling of dystrophin-glycoprotein complex, intercalated disk proteins, and contractile proteins in the hearts of mice subjected to sepsis induced by cecal ligation and puncture. / Remodelamento do complexo de glicoproteínas associadas à distrofina, do disco intercalar e das proteínas contráteis no coração de camundongos submetidos à sépsis induzida por ligação e perfuração do ceco
Sepsis and septic shock represent a complex syndrome of systemic inflammatory response, with multiple physiological and immunological abnormalities, commonly caused by bacterial infection. The most important consequence of the response is the involvement of many organs and tissues. Cardiac dysfunction, caused by impairment in myocardial contractility, has be

28. Metabolismo do dibenzotiofeno por Cunninghamella elegans associados aos estudos morfolÃgicos e ultraestruturais
Considering the biotechnological potential of Cunninghamella elegans related to recalcitrant compounds in the environment the aim of this work was to evaluate the dibenzothiophene (DBT) degradation in association with morphological and ultrastructral aspects. Samples treated with DBT were submitted to gas chromatography coupled to mass spectrometry - GC-MS.

29. Cytoskeleton, endoplasmic reticulum and nucleus alterations in CHO-K1 cell line after Crotalus durissus terrificus (South American rattlesnake) venom treatment
Snake venoms are toxic to a variety of cell types. However, the intracellular damages and the cell death fate induced by venom are unclear. In the present work, the action of the South American rattlesnake Crotalus durissus terrificus venom on CHO-K1 cell line was analyzed. The cells CHO-K1 were incubated with C. d. terrificus venom (10, 50 and 100g/ml) for

30. Smooth muscle cell behavior of rat ventral prostate after androgen deprivation in vivo and mechanical stretch assay in vitro / Comportamento da celula muscular lisa da prostata ventral de ratos apos privação androgenica in vivo e sob estiramento mecanico in vitro
Smooth muscle cells (SMC) are the main component of the prostatic stroma and play important roles in the organ physiology, acting on the contraction associated with ejaculation and on the remodeling related to neoplasias or androgen deprivation, on the production of paracrine factors and the synthesis/degradation/reorganization of extracellular matrix compon

31. Análise proteômica comparativa entre neutrófilos não ativados e ativados com PMA, um análogo do diacilglicerol
Neutrophils are the major type of leukocytes in peripheral blood and protect against fungal and bacterial infections. Directed migration in a gradient of chemotactic stimuli enables these cells to rapidly find the site of infection and destroy the invading pathogens. PMNs can exist in three different activation states, namely, resting, primed, and activated

32. Expressão gênica diferencial de fibroblastos de linfonodos comprometidos ou não comprometidos de pacientes com câncer de mama após cultura isolada ou co-cultura com células epiteliais mamárias normais ou malignas / Differential gene expression of fibroblasts from involved or uninvolved lymph nodes from breast cancer patients cultured alone or cocultured with normal or malignant mammary epithelial cells
Tumor development may be influenced by epithelial-mesenchimal interactions in the primary site as well as in the involved lymph node from breast cancer patients. Our aim was to evaluate the proliferation rate and gene profile of fibroblasts obtained from involved and uninvolved lymph nodes from breast câncer patients and to determine the influence of normal

33. Dexamethasone blocks the migration of the human neuroblastoma cell line SK-N-SH
Glucocorticoids (Gc) influence the differentiation of neural crest-derived cells such as those composing sympathoadrenal tumors like pheochromocytomas, as well as neuroblastomas and gangliomas. In order to obtain further information on the effects of Gc on cells evolving from the neural crest, we have used the human neuroblastoma cell line SK-N-SH to analyze

34. Efeito da cisplatina em cultura de linhagens estabelecidas e sua capacidade de induzir transformação celular in vitro / Effesct of cisplatin on culture cell lines and its ability to induce cellular transformation in vitro
Cisplatin is an antineoplastic agent used to treat solid malignancies, such as testicular, ovarian and bladder tumors. However, both in vitro and in vivo, cisplatin has been shown to be mutagenic, genotoxic and tumorigenic. Maintained in culture, Vero cells presented behavioral and morphological alterations associated with cellular transformation in vitro, a

35. Changes in cell shape, cytoskeletal proteins and adhesion sites of cultured cells after extracellular Ca2+ chelation
Although much is known about the molecules involved in extracellular Ca2+ regulation, the relationship of the ion with overall cell morphology is not understood. The objective of the present study was to determine the effect of the Ca2+ chelator EGTA on the major cytoskeleton components, at integrin-containing adhesion sites, and their consequences on cell s

36. The cytoskeleton of the electric tissue of Electrophorus electricus, L.
The electric eel Electrophorus electricus is a fresh water teleost showing an electrogenic tissue that produces electric discharges. This electrogenic tissue is distributed in three well-defined electric organs which may be found symmetrically along both sides of the eel. These electric organs develop from muscle and exhibit several biochemical properties an
