25. Desenvolvimento placentário em quatis: evolução filogenética em carnívoros? / Placental development in quati: phylogenetic evolution in carnivores?
The importance of preservation of brazilian wild species is based on knowledge of their distribution, behavior in the wild and in captivity, and the detailed description of their reproductive biology in order to perpetuate the specie. One of the main impacts of this study is the scientific details of the uterine environment versus the process of placentation

26. Imunoexpressão de caderinas e integrinas no desenvolvimento do epitélio cutâneo humano / Immunoexpression of cadherins and integrins in the development of human skin epithelium
Introduction: Cadherins and integrins are important for maintenance of tissue integrity and in signal transduction during skin development. Distribution of these molecules in human skin development was investigated and associated with markers of differentiation, cytokeratins (CK) and involucrin (INV). Methods: Using immunohistochemistry expression of E- and

27. Modelos para a produção de eritropoietina recombinante humana in vivo e in vitro com vetores plasmideais em ovinos / Models for the production of human recombinant erythropoietin in vivo and in vitro with plasmidial vectors in ovine
Some post-translational modifications are necessary for the production of biopharmaceutical proteins, such as recombinant human erythropoietin (rhEPO), with a good specific action and a high biological activity. These modifications are obtained only by bioreactors based on eukaryotic cell as mammary cells. Bioreactors, in vivo or in vitro, with this kind of

28. Disgerminoma bilateral e hiperplasia endometrial cística com piometra em cadela = Bilateral Dysgerminoma and Cystic Endometrial Hyperplasia with Pyometra in a bitch / Bilateral Dysgerminoma and Cystic Endometrial Hyperplasia with Pyometra in a Bitch
Background: Ovarian tumors are considered rare both in dogs and cats. Germ cell neoplasms correspond to approximately 15% of the cases and can be classified into dysgerminomas, teratomas and teratocarcinomas. Reports of bilateral dysgerminoma in dogs and cats are rare. The aim of this work was to describe a case of bilateral dysgerminoma and cystic endometri

29. Conidiobolomicose em ovinos: reavaliação de três casos previamente diagnosticados como tumor etimoidal enzoótico
Conidiobolomycosis is an infection caused by fungi of the genus Conidiobolus spp. that is associated with a granulomatous rhinitis in humans and animals. In sheep, the disease is clinically characterized by respiratory changes, exophthalmia, craniofacial asymmetry, and fever. Microscopically, there are multifocal granulomas containing intralesional hyphae. F

30. Triple-negative breast carcinomas are a heterogeneous entity that differs between young and old patients
OBJECTIVE: To compare the frequency and immunohistochemical profiles of triple-negative breast carcinomas in younger and older women. METHODS AND RESULTS: We selected patients diagnosed with triple-negative breast carcinomas. The groups examined were women who were 35 years old or younger between 1997 and 2007 (n = 74) and, for comparison, women who were 60

31. Fatores hepatotróficos modulam a capacidade proliferativa em cultura primária de hepatócitos de ratos normais / Hepatotrophic factors modulate the proliferative potential in primary hepatocyte cultures of normal rats
A utilização de fatores hepatotróficos (FH) tem trazido importantes avanços no tratamento de algumas doenças hepáticas. A avaliação dos efeitos dessas substâncias pode ser feita com o uso de modelos in vivo, como a regeneração hepática após a hepatectomia parcial ou in vitro, como a cultura de hepatócitos, células estreladas ou outros tipos ce

32. Histopathological characterization of a syngeneic orthotopic murine bladder cancer model
PURPOSE: We developed and characterized by histopathology and immunohistochemistry a syngeneic murine bladder tumor model derived from the MB49 tumor cell line. MATERIALS AND METHODS: Bladder tumor implantation was achieved by intravesical instillation of 5 x 10(5) MB49 tumor cells in C57BL/6 mice. A chemical lesion of the bladder was performed in order to p

33. Cytokeratin 19 expression in the peripheral blood mononuclear fraction of prostate cancer patients / Expressão do transcrito da citoqueratina 19 (CK-19) na fração mononuclear do sangue periférico em pacientes com adenocarcinoma de próstata
Introdução: O emprego da técnica de RT-PCR na detecção da expressão de genes epiteliais como a CK-19 no sangue periférico de pacientes com câncer de próstata é uma oportunidade para avaliar a progressão tumoral ao nível molecular na ausência de doença clinicamente mensurável. Material e métodos: Inicialmente 10 pacientes com nível sérico de

34. Rhabdoid choroid plexus carcinoma: a rare histological type
Primary central nervous system atypical teratoid/rhabdoid tumors mostly occur during early childhood and are almost invariably fatal. These tumors show similar histological and radiological features to primitive neuroectodermal tumor, meduloblastoma and choroid plexus carcinoma, but present different biological behaviors. We present the case of an 18 year-ol

35. Detection and characterization of epithelial cells in the peripheral blood of patients with breast cancer / Detecção e caracterização de células epiteliais no sangue periférico de pacientes com carcinoma localmente avançado de mama
The aim of this study was to detect and characterize carcinoma cells of patients with breast cancer with clinical stage III analyzing the presence or absence before chemotherapy by enrichment of peripheral blood with super paramagnetic microbeads, using direct Immunomagnetic labeling of intracellular 7/8 cytokeratin. For enrichment, magnetically labeled tumo

36. Endometrial protein expression during the luteal phase of the menstrual cycle / Expressão protéica no endométrio durante a fase lútea do ciclo menstrual
Introduction: The objective of this study was to evaluate endometrial protein expressions from fertile and infertile women during the luteal phase of the menstrual cycle by immunohistochemistry in tissue microarrays (TMA). Method: The expression of ten proteins obtained from 52 endometrial samples in the initial, mid (window of implantation) and late (premen
