25. ExpressÃo tecidual da proteÃna cerbB-2 em mulheres portadoras de doenÃas tumorais de mama
The cerbB-2 protein has been sufficiently studied for its importance as prognostic factor of the breast cancer, mainly in the chemotherapy associations. To eliminate the subjectivity in the interpretation of the conventional immunohistichemistry method, this study aims to quantify, morphometrically, the immunostain of the cerbB-2 protein expressed in breast

26. Maspin expression in axilla-negative breast cancer: correlation with recurrence and prognostic factors. / Expressão da maspina no câncer mamário axila-negativo: correlação com a recidiva tumoral e com fatores prognósticos.
O câncer de mama é a neoplasia maligna de maior incidência em mulheres no mundo e no Brasil. A utilização de fatores prognósticos é importante na individualização dos grupos de prognóstico favorável e desfavorável. As metástases axilares são consideradas o fator mais relevante no câncer de mama, pois as pacientes com linfonodos axilares compro

27. Reduction of growth and resistance cellular of mammary carcinoma after silencing of gene PIF/DCD (Proteolysis-inducing Factor) by shRNAi. / Redução do crescimento e resistência celular de carcinoma mamário após silenciamento do gene PIF/DCD (Proteolysis-Inducing Factor) via shRNAi.
A expressão do PIF/DCD em tumores tem sido relacionada ao crescimento e resistência à morte celular e à indução de caquexia em camundongos. O objetivo deste estudo foi investigar o papel do PIF/DCD nestes processos. Foram construídos três PIF/DCD-RNAi chamados de IBC-I, II, III e pKLO (controle), compreendendo diferentes áreas do mRNA, geramos clone

28. Localização histologica das metastases nos linfonodos sentinelas e fatores de risco para predizer positividade dos linfonodos não-sentinelas em cancer de mama / Histologic localization of sentinel lymph nodes metastases and risk factors for prediction of non-sentinel lymph nodes positivity in breast cancer
INTRODUCTION: The complete axillary lymph node dissection is the standard treatment for patients with positive sentinel lymph node (SLN) in breast cancer. However, several studies report that 38 to 67% of patients with positive SLN do not have involvement of the non-sentinel lymph nodes (NSLN). OBJECTIVE: The purpose of this study is to explore the orphologi

29. Expressão de PRSS11, MTSS1, CLPTM1, SMYD2, NOTCH1 e RPL37A em fatias de carcinoma de mama de cadelas e correlação com resposta à doxorrubicina in vitro / Expression of PRSS11, MTSS1, CLPTM1, SMYD2, NOTCH1 and RPL37A in slices of bitch mammary cancer and correlation with response to exposure doxorubicin in vitro
Mammary gland tumors are the most common neoplasias of bitches and doxorubicin is one the mainstay drugs used in their treatment. Neoadjuvant chemotherapy with doxorubicin not only reduces the primary tumor as well as allows an in vivo evaluation of tumor response. Predictive markers of response, if identified, might allow a tailored treatment of each patien

30. Regulating factors of angiogênese and tumoral infiltration in positive the mammary carcinomas for citoqueratina 5 / Fatores reguladores da angiogênese e infiltração tumoral nos carcinomas mamários positivos para a citoqueratina 5
O reconhecimento de subtipos de carcinomas mamários baseados em suas características moleculares trouxe novas perspectivas na investigação do câncer de mama. Algumas proteínas chaves reguladoras da angiogênese e da infiltração tumoral foram avaliadas em carcinomas de mama de fenótipo basal (CK5+). Foi realizado estudo Imunoistoquímico com 14 antic

31. ESTUDO RETROSPECTIVO DE LESÕES HEPÁTICAS CRÔNICAS EM CÃES / CHRONIC HEPATIC LESIONS OF DOGS. A retrospective study
The necropsy reports of 4899 dogs necropsied at the Veterinary Pathology Laboratory of the Universidade Federal de Santa Maria from 1964 to 2003 were reviewed in search of chronic hepatic lesions. Three hundred and six lesions (6,2%) were found and were classified as inflammatory (4,2%), degenerative (26,8%), circulatory (23,2%) and neoplastic (45,8%). Neopl

32. Does the correlation between EBNA-1 and p63 expression in breast carcinomas provide a clue to tumorigenesis in Epstein-Barr virus-related breast malignancies?
Several investigators have identified Epstein-Barr virus (EBV) particles in breast carcinomas, a fact that supports a role for EBV in mammary tumorigenesis. The possible mechanism involved in this process is not clear. The present study was carried out in an attempt to determine whether there is a relationship between latent infection with EBV and p53 and p6

33. AvaliaÃÃo do Ãster de acridina como marcador conjugado à lectina em histoquÃmica
Neoplasic cell transformations present differences in the composition and distribution of oligosaccharides in cell surface glicoproteins and glicolipids. Lectins have been used as auxiliary tools in histopathologic diagnosis to mammary, uterus and brain tissues, for example. Chemiluminescence is a technique with low detection threshold and large dynamic spec

34. Decorin is one of the proteoglycans expressed in Walker 256 rat mammary carcinoma
Proteoglycan and glycosaminoglycan content was analyzed in a model of rat mammary carcinoma to study the roles of these compounds in tumorigenesis. Hyaluronic acid and proteoglycans bearing chondroitin and/or dermatan sulfate chains were detected in solid tumors obtained after subcutaneous inoculation of Walker 256 rat carcinoma cells. About 10% of sulfated

35. Efeito da quimioterapia primaria no carcinomade mama com diametro entre 21 e 50mm : avaliação clinica, mamografica e anatomopatologica
The carcinoma of the breast whose largest diameter is between 21mm and 50mm is considered a potentially operable tumor. Nowadays , the routine protocol of treatment consists of an initial surgical procedure, generally a radical mastectomy, followed by adjuvant chemotherapy. Since the late eighties some studies have arisen using the primary chemotherapy prior
