49. Investigação da microbiota endofítica onipresente em microplantas "axênicas / Investigation of ubiquitous endophytic microbiota in "axenic" microplants.
Tissue culture has been an important tool widely used for various purposes, among them the micropropagation has been highlighted due to the rapid production of healthy seedlings in a small space. Within this context, the term axenic plant has been distributed as an ideal to be achieved in this technique, which the search based on numerous methods that effect

50. Ação do paratormônio humano (1-34) no tecido ósseo de ratas osteopênicas. / Action of parathyroid hormone (1-34) on bone tissue in osteopenic rats.
Introduction: Bone remodeling depends upon a variety of systemic and local factors. Systemic factors that have a direct effect include the parathyroid hormone which together with other factors maintains bone homeostasis. Biosynthetic human parathyroid hormone (1-34) [hPTH(1-34)] has been used to stimulate bone formation in patients with osteoporosis. However

51. Non genomic actions of triiodothyronine (T3) on the expression polyadenylation and distribution of TSH granules in thyrotrophs of hypothyroid rats / Ações não genômicas da triiodotironina (T3) sobre a expressão, poliadenilação e distribuição dos grânulos de TSH nos tireotrofos de ratos hipotireiodeos
The thyroid-stimulating hormone (TSH) is the main regulator of the synthesis and secretion of thyroid hormones (TH), which exert a negative feedback mechanism in the pituitary by reducing the synthesis of β and α (CGA - Glycoprotein hormones alpha chain) chains through mechanisms that involve changes in the tra

52. Morfoquantitative and chemical coding analyses of the purinergic P2X2 receptor in myenteric plexus of female and male obese mice (ob/ob). / Análises morfoquantitativa e do código químico do receptor purinérgico P2X2 no plexo mioentérico do íleo de camundongos obesos fêmeas e machos (ob/ob).
The intestinal activities are coordinated by enteric nervous system, and dysfunctions in intestinal motility were observed in obese individuals. The enteric neurons have been demonstrated to express different purinergics receptors. This study aims to analyze the expression of P2X2 receptor and the chemical code in the myenteric neurons in obesity. Sample fro

53. Sporadic medullary thyroid carcinoma: clinical data from a university hospital
INTRODUCTION: Medullary thyroid carcinoma may occur in a sporadic (s-medullary thyroid carcinoma, 75%) or in a multiple endocrine neoplasia type 2 form (MEN2, 25%). These clinical forms differ in many ways, as s-medullary thyroid carcinoma cases are RET-negative in the germline and are typically diagnosed later than medullary thyroid carcinoma in MEN2 patien

54. HistoquÃmica com lectinas de sementes de Cratylia mollis analisando tecidos prostÃticos humanos
Prostate cancer is a malignant tumour of major incidence in elderly men in the developed countries and the second major cause of death for cancer. Lectins are proteins or glycoproteins, which recognize specifically and reversibly free or conjugated carbohydrates. They have been used in histochemistry to evaluate changes in the composition and expression of c

55. 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

56. ASPECTOS MORFOLÓGICOS DO PREPÚCIO DE CRIANÇAS PORTADORAS DE HIPOSPÁDIA COM E SEM O USO DE CREME DE TESTOSTERONA A 1%
The goal of this study is to analyze the different histological features of the foreskins of children with hypospadia, that has and has not recieved application of testosterone cream, and compare them with circumcised patients. The foreskin of 09 circumcised children (G1), 13 children with hypospadia, who did not receive testosterone (G2), and 13 children wh

57. Congenital hidranencephaly and cerebellar hypoplasia in water buffaloes / Hidranencefalia e hipoplasia cerebelar congênita em búfalos Murrah
Hereditary hydrancephaly and cerebellar hypolasia are reported in Murrah buffalos. Six calves, one female and 5 male out of 128 born between 2004 and 2008 in a farm in southern Brazil were affected. All affected calves were offspring from the same bull. No affected buffaloes were observed in the descendants of other three bulls used in the farm. Main clinica

58. Morphology of the alimentary canal of the gecko Hemidactylus mabouia (Moreau de Jonnès, 1818) (Squamata: Gekkonidae) / Morfologia do tubo digestivo da lagartixa Hemidactylus mabouia (Moreau de Jonnès, 1818) (Squamata: Gekkonidae).
Hemidactylus mabouia is the gecko species more thoroughly distributed in Brazil, being common in anthropic atmospheres, what turns easy its use as model for study of the reptiles. Likewise, aiming at to describe morphologically the alimentary canal of H. mabouia, 17 adult specimens were used, being collected fragments of the esophagus, of the oesophagogastri

59. Estudo da toxicidade da Ipomoea carnea em ratas durante o período perinatal. Avaliação dos possíveis efeitos lesivos no tecido placentário / Ipomoea carnea toxicity study in rats during perinatal period. Evaluation of possible harmful effects on the placental tissue
A Ipomoea carnea é uma planta tóxica amplamente distribuída no Brasil e em outros países tropicais. Durante os períodos de seca esta planta se mantém verde, podendo servir como fonte de alimento para os animais de produção. A intoxicação natural é de caráter crônico e ocorre quando ruminantes particularmente, caprinos ingerem a planta, estes ani

60. Diversity among satellite glial cells in dorsal root ganglia of the rat
Peripheral glial cells consist of satellite, enteric glial, and Schwann cells. In dorsal root ganglia, besides pseudo-unipolar neurons, myelinated and nonmyelinated fibers, macrophages, and fibroblasts, satellite cells also constitute the resident components. Information on satellite cells is not abundant; however, they appear to provide mechanical and metab
