14. Aspectos epidemiológicos da neoplasia mamária canina / Epidemiological aspects of canine mammary tumor
Tumor de mama é a neoplasia mais freqüente em cadelas, entretanto, há controvérsias sobre os fatores que influenciam o desenvolvimento do tumor. O objetivo deste trabalho foi estudar o perfil das cadelas com tumor de mama atendidas no Hospital de Clínicas Veterinárias da Universidade Federal do Rio Grande do Sul (HCV-UFRGS). Foram coletados os dados de

15. Efeito da vitamina D no perfil transcricional de cultura organotípica de câncer de mama / Vitamin D effect in the transcriptional profile of breast cancer organotypic culture
High 1,25(OH)2D3 (VD) concentrations (10-100nM) exerts antiproliferative effects and modifies gene expression profile in breast cancer (BC) cell lines. However, studies conducted in cell lines disconsider stromal-epithelium interactions, which are known to regulate breast cancer development. Besides, high VD concentrations may cause hypercalcemia in vivo. Ou

16. Polymorphism in CYP17, GSTM1 and the progesterone receptor genes and its relationship with mammographic density
Radiologic breast density is one of the predictive factors for breast cancer and the extent of the density is directly related to postmenopause. However, some patients have dense breasts even during postmenopause. This condition may be explained by the genes that codify for the proteins involved in the biosynthesis, as well as the activity and metabolism of

17. Padronização de modelo de carcinogênese mamária induzido quimicamente por DMBA em camundongos / Standardization of a mammary carcinogenesis chemically model induced by DMBA in mice
O câncer de mama permanece como o segundo tipo de câncer mais freqüente no mundo e o primeiro entre as mulheres (INCA, 2007). Porém, os mecanismos envolvidos no processo de gênese dos tumores mamários mesmo sendo intensamente estudados nos últimos 30 anos, ainda não são bem definidos. Vários estudos apontam que a susceptibilidade em função da gen

18. Histological study, immunohistochemistry and cell culture of normal tissues and cancer of the breast and human dog / Estudo histológico, imuno-histoquímico e de cultura de células de tecidos normais e cancerosos da mama humana e canina
O câncer está incluído entre as entidades patológicas que mais acometem a mama feminina. A cada ano, cresce o número de mulheres acometidas pelo câncer de mama e também as pesquisas sobre a biologia desse tumor, aí incluídas aquelas que utilizam modelos animais, principalmente os tumores de mama de cadelas. Este trabalho teve como objetivo desenvolv

19. Carcinoma ductal invasivo mamÃrio esporÃdico: uma abordagem histoquÃmica e imunohistiquÃmica
Breast cancer is the most frequent neoplasia and the main cause of cancer death in women worldwide. Among the several types of mammary gland neoplasia Invasive Ductal Carcinoma (IDC) represents 65% to 80% of all carcinomas. The major problem concerning this neoplasia is the great genotypic and phenotypic heterogeneity. This feature explains the increasing se

20. Câncer de mama e organização de serviços: do atendimento básico à referência na Casa de Saúde Santa Marcelina Itaquera, no município de São Paulo / Breast cancer and organization of services: the problem of the delayed diagnosis and treatment in patients of the Casa de Saúde Santa Marcelina unidade Itaquera of the city of São Paulo
Introduction: The breast cancer is one of the most extensively studied cancers worldwide in many aspects, including in relation to its epidemiological characteristics, some very peculiar. This is due to the fact that breast cancer in women is one of the most important causes of morbidity and mortality from cancer in almost all populations of the planet since

21. DETECTION OF MASSES IN MAMMOGRAPHY IMAGES USING CELLULAR NEURAL NETWORKS, STATISCAL FUNCTIONS VECTOR MACHINES AND SUPPORT / DETECÇÃO DE MASSAS EM IMAGENS MAMOGRÁFICAS USANDO REDES NEURAIS CELULARES, FUNÇÕES GEOESTATÍSTICAS E MÁQUINAS DE VETORES DE SUPORTE
Breast cancer presents high occurrence frequency among the world population and its psychological effects alter the perception of the patients sexuality and the own personal image. Mammography is an x-ray of the mamma that allows the precocious detection of cancer, since it is capable to showing lesions in their initial stages, typically very small lesions i

22. Redução da biocarga e garantia de esterilidade em implantes mamários de silicone / Bioburden reduction and sterility assurance in silicone gel breast implants
Silicone breast implants consist of biomaterials widely used in breast reconstitution surgeries after the occurrence of cancer, accidents, breast size correction (in case of different volume between both breasts)or in mammary augmentation for esthetic reasons. With a view to confer security in its application, directly related to patients health, great atten

Avaliação do dano radioinduzido, capacidade de reparo e morte cecular em células humanas tumorais (T-47D e MCF-7) e não tumorais (MCF-10) de mama / Evaluation of the radioinduced damage, repair capacity and cell death on human tumorigenic (T-47D and MCF-7) and nontumorigenic (MCF-10) cell lines of breast
Breast cancer is one of the most common malignancies that account women, representing about one in three of all female neoplasm. Approximately, 90% of cases are considered sporadic, attributed to somatic events and about 10% have a family history and this only 4 - 5 % is decurrent of hereditary factors. In the clinic, ionizing radiation is a major tool utili

24. Transcriptional up-regulation of PHLDA1 by 17β-estradiol in MCF-7 breast cancer cells
Most breast cancer risk factors are associated with prolonged exposure of the mammary gland to high levels of estrogens. The actions of estrogens are predominantly mediated by two receptors, ERα and ERβ, which act as transcription factors binding with high affinity to estrogen response elements in the promoter region of target genes. However, most target g
