A UNIFEOB mantém uma política de pesquisa que tem como objetivo orientar as ações desenvolvidas nesse campo do conhecimento. As pesquisas têm alicerce em princípios e critérios de produção de conhecimento científico e tecnológico, seguindo normas éticas de pesquisa em seres humanos e animais e dissociada do ensino e da extensão. As atividades convergem com as diretrizes nacionais, visando o desenvolvimento sustentável social, econômico e ambiental.

    Estudo morfológico sobre testículos do tatu galinha
    (Fundação de Ensino Octávio Bastos, 2001-11-30) LIMA, Marcelo C. de; CARVALHO, Ana Flávia de; AMBRÓSIO, Carlos Eduardo; BONATELLI, Marina
    Anatomically, the testicles were located in the hypogastric, intra abdominal region in a longitudinal cranial - caudal position with an oval shape. The epididymis was found in the dorsal mid region of the testis DYCE et al (1997). The right testicle weighed 6.48 g and the left 6.23 g; they respectively measured 3.1 cm and 3.4 cm in length and 2.6 cm and 2.6 cm in width, showing a certain regularity in shape and size. The right epididymis measured 8.5 cm and the left 6.0 cm. Microscopically the testicular structures found were similar to those of other animals with characteristic germinal epithelium (spermatogonia, spermatocytes of 1st and 2nd order and spermatoids). Leydig cells were observed in large numbers.

    Análise morfológica das células do aspirado medular de fetos caninos
    (Centro Universitário da Fundação de Ensino Octávio Bastos, 2011-05-30) MÁRIO, Lara Carolina; BORGHESI, Jéssica; MELLO, Ana Carolina Landentin; MIGLINO, Maria Angélica; AMBRÓSIO, Carlos Eduardo; MARTINS, Daniele; CARVALHO, Ana Flávia de; WENCESLAU, Cristiane Valverde
    The adult bone marrow is a source of stem cells (CT), which include the hematopoietic stem cells (HSC) that originate the entire definitive hematopoietic lineage; and mesenchymal stem cells (MSC), and or stromal which are responsible for providing a favorable environment for hematopoiesis. In addition to these main cell types, bone marrow is composed of several parents, differentiated cells and an extracellular matrix. This environment where CT is found is called a niche, as it houses a large amount of CT and cellular progenitors that are kept quiescent, acting normally and or in the face of injuries. However, little is known about the fetal bone marrow niche. It is known that the bone marrow niche is derived during the ontogenesis of the yolk sac, which subsequently migrates to various hematopoietic organs such as the placenta and liver, ultimately settling in the bone marrow. Thus, the present work aims to describe morphologically the cell types of canine fetal bone marrow at 40 and 60 days of gestation. For this purpose, 6 pregnant female uteri were used to collect the medullary aspirate from the femur bone and later structural and ultrastructural morphological analysis. The results demonstrated that the canine fetal bone marrow at 60 days of gestation has cell types similar to that of the adult bone marrow as well as CT, thus being able to be used as a source of CT isolation.

    Membranas embrionárias e fetais de equinos sob análise de microscopia eletrônica de transmissão
    (Centro Universitário da Fundação de Ensino Octávio Bastos, 2009-09-30) NASCIMENTO, Priscila Leal do; MANÇANARES, Celina Almeida Furlanetto; MIGLINO, Maria Angélica; AMBRÓSIO, Carlos Eduardo; FRANCIOLLI, André Luis Rezende; FERRAZ, Ana Cláudia Cristiane; MANÇANARES, Ana Carolina Furlanetto; CARVALHO, Ana Flávia de
    To develop this research, 16 pregnant uteri were used, of which 16 placentas were obtained divided into groups of different stages of development. The material was collected from adult, mixed breed mares up to 100 days of gestation. The membranes were intended for ultra-structural analysis and the results obtained under transmission electron microscopy (MET) were similar to those found by ASSIS-NETO (2005), in bovine membranes, and ITURRIZAGA (2005), in llamas. The fetal membranes did not show relevant structural differences in the different periods studied. The chorion showed columnar epithelium; mesenchymal tissue rich in collagen fibers, the trophoblastic cells being uni, binucleated and rarely trinucleated. A large number of mitochondria were present mainly at the apex of cells. The allantoic presented a simple columnar epithelium with globular nuclei and a large concentration of mitochondria at the cell apex, in the cell base there was a large amount of rough endoplasmic reticulum. The amnion showed a simple, squamous epithelium and at the cellular apex there was a large amount of electrondense granules covered by a rounded halo. The yolk sac epithelium varied from globose to columnar, with uni or binucleate cells in a single layer, with a large amount of rough endoplasmic reticulum, uniformly distributed. Between the endodermal cells, intercellular spaces were found. So far, it is concluded that the mare's placenta is choroidal alloid, epithelial, diffuse, non-deciduous and villous, with corium cells and a yolk sac with characteristics of protein secretion, while amnion presented secretion vesicles, but with less amount of rough endoplasmic reticulum.
