37. Endoscopia digestiva alta na rede pública de saúde : diagnósticos de lesões do tubo digestivo alto em uma população de atendimento primário na região sudoeste do município de Campinas, São Paulo - Brasil = Endoscopy in public health : diagnoses of lesions in the upper digestive tract in a population of primary care in the region southwest of the city of Campinas, São Paulo - Brazil / Endoscopy in public health : diagnoses of lesions in the upper digestive tract in a population of primary care in the region southwest of the city of Campinas, São Paulo - Brazil
Upper digestive tract endoscopy (UDTE) is one of the most highly indicated exams for the investigation of upper digestive tract diseases. It is normally performed in high-complexity hospitals and specialized clinics; however, the high demand for UDTE examinations and the growing number of professionals specializing in endoscopic techniques have resulted in a

38. Análise de genes diferencialmente expressos nas vias de sinalização (Hedgehog e Wnt) em carcinomas basocelulares humanos
Hedgehog (HH) and Wingless-Int (Wnt) signaling pathway are related to the process of cellular proliferation, differentiation, angiogenesis, matrix remodeling and homeostasis of stem cells. Over the years, several mutations in HH signaling pathway have been identified, including the loss of function mutations in ptch1 and the gain of function mutations in smo

39. Desenvolvimento e caracterização de dispositivo de PLLA/Trietil-Citrato associado à derme suína acelular para reparação de lesões cutâneas / Development and characterization of PLLA/Triethyl citrate device associated to acellular dermal matrix to repair cutanous wounds
One of the challenges of the Tissue Engineering is to promote a better functioning of organs and tissues damaged by diseases or traumas. With target for developing a biphasic device for future regeneration and dermal application in Tissue Engineering and Regenerative Medicine, fibroblasts from VERO cell line were cultivated on a porcine acellular dermal matr

40. Evaluation of a radiographic method to detect tibial dyschondroplasia lesions in broilers
This study aimed at developing radiographic techniques for the early detection of dyschondroplastic lesions in the tibia of broilers. The experiment was carried out at the facilities of UNIFOR/MG and Formiga and UNIFENAS/ Alfenas with 420 one-day-old male Cobb broilers. At 20 days of age, all birds were radiographed and identified with an alpha-numeric metal

41. Experimental model of heterotopic ossification in Wistar rats
Heterotopic ossification (HO) is a metaplastic biological process in which there is newly formed bone in soft tissues adjacent to large joints, resulting in joint mobility deficit. In order to determine which treatment techniques are more appropriate for such condition, experimental models of induced heterotopic bone formation have been proposed using hetero

42. Comparative studies on the histology and ultrastructure of the siphons of two species of Tellinidae (Mollusca: Bivalvia) from Brazil
Despite the great importance of the siphons for infaunal bivalves, only a few studies have examined their tissues using histology techniques or scanning electron microscopy. In the present study, the siphons of Tellina lineata Turton, 1819 and Macoma biota Arruda & Domaneschi, 2005 were investigated. The siphon walls are composed by a series of muscle sheets

43. Restoration of the rabbit corneal surface after total epithelial debridement and complete limbal excision
How is the corneal epithelium restored when all of it plus the limbus have been eliminated? This investigation explored the possibility that this may be achieved through the conjunctival epithelium. The corneal epithelium of the right eye of 12 rabbits (Oryctolagus cuniculus) was totally scraped followed by surgical excision of the limbus plus 1.0-1.5 mm of

44. Ethnobotanic study of Randia aculeata (Rubiaceae) in Jamapa, Veracruz, Mexico, and its anti-snake venom effects on mouse tissue
In Mexico, medicinal plants are widely used. The use of Randia aculeata by healers against snakebites has never been scientifically tested in relation to possible effects on blood parameters and muscle tissue damage. Interviews were carried out in Jamapa, Veracuz, Mexico, with local residents to collect information about the traditional use of Randia aculeat

45. Alterações morfológicas de Tilápias do Nilo (Oreochromis niloticus) (Linnaeus, 1758) expostas às águas da represa Billings. / Morphologic alterations of Nile Tilapia (Oreochromis niloticus) (Linnaeus, 1758) exposed to waters of Billings dam.
The Billings dam shows eutrophic waters due to the large amount of sewage from urban occupation neaby, and consequently, the fish can be a public health problem. The gills and liver become target organs for the action of pollutants in the aquatic environment and may present several levels of biological organization. These biological responses to stress cause

46. Controle hormonal da próstata feminina do gerbilo sob influência de múltiplas prenhezes e reposição hormonal / Hormonal control of the gerbil s female prostate : influence of multiple pregnancies and hormone replacement
The gerbil female prostate is located paraurethrally and has all the main histological components of the male prostate, like secretor epithelium and fibromuscular stroma. This gland, like the prostate in males, is targeted by testosterone action, which promotes morphofunctional development. Furthermore, estrogens are required to maintain the male and female

Desenvolvimento de técnica de análise de imagens digitais para avaliação do estágio da fibrose em biópsias hepáticas de pacientes portadores de hepatite crônica por vírus da hepatite B e C / Development of a digital image analysis technique for the evaluation of fibrosis stage in liver biopsies of HBV and HCV patients
The hepatitis caused by viruses are the most frequent, principally the virus B (HBV) and C (HCV) hepatitis. The anatomopathologic study of the liver biopsy is considered the gold standard for the evaluation of architectural distortion and degree o fibrosis of the livers parenchyma, important prognostic factors for the patients with chronic viral hepatitis.

48. Tissue reaction to Endométhasone sealer in root canal fillings short of or beyond the apical foramen
OBJECTIVE: This study evaluated the response of periapical tissues to the endodontic sealer Endométhasone in root canal fillings short of or beyond the apical foramen. MATERIAL AND METHODS: Twenty root canals of premolars and incisors of 2 mongrel dogs were used. After coronal access and pulp extirpation, the canals were instrumented up to a size 55 K-file
