37. Morphometric study of acinar autolysis in sublingual glands of rats: its relation with interval post mortem and the formalin volume post mortem / Estudo morfométrico da autólise acinar em glândulas sublinguais de ratos: sua relação com intervalo post mortem e o volume do fixador
A autólise acinar post mortem em glândulas sublinguais humanas é um fenômeno que prejudica a sua análise microscópica. Com o objetivo de esclarecer e prevenir tal ocorrência, a presente investigação foi planejada no sentido de analisar morfometricamente as possíveis influências do intervalo post mortem (IPM) e do volume de fixador histológico (VF

38. Preservação do sistema genital de chinchila (Chinchilla lanigera) para avaliação em microscopia de luz
The preservation of chinchilla genital organs using a fixed solution of paraformaldehyde 10% buffered and a saturated solution of Bouin during 4, 12 and 18 hours of fixation, inclusion in paraffin and staining with hematoxylin-eosin was evaluated. The Bouin solution with 12 hours of fixation was the best protocol of fixation for the ovaries, oviduct, uterus

39. Influência de diferentes microestruturas de implantes osseointegráveis sobre o tecido ósseo peri-implantar: avaliação histomorfometrica em humanos
Studies have demonstrated that roughness dental implant surfaces show firmer bone fixation and an increased percentage of bone-to-implant contact (BIC%) compared to commercially pure titanium surface (machined) implants. It has also been suggested that implants with roughness surfaces can be loaded earlier then machined implants. Therefore, the purpose of th

40. Characterization of Brazilian isolates of equine herpesvirus type A / Caracterização genomica de isolados brasileiros do herpesvirus equino do tipo 1
Equine Herpesvirus Type 1 (EHV-1) is a member of Alphaherpesvirinae subfamily implicated with abortions, respiratory and neurological disturbs in horses. The principal mode of viral transmission is through close contact virus-containing secretions of infected horses. Systemic pathogenesis in which this virus is implicated combines primary respiratory infecti

41. Prevalencia, tratamento e complicações dos casos de trauma facial atendidos pela FOP - Unicamp de abril de 1999 a março de 2004 / Prevalence, treatment and complications of facial injuries evaluated by Piracicaba Dental School ? State University of Campinas, from April 1999 to March 2004
This study is based on an observational, prospective and longitudinal research with the purpose of analyzing the prevalence, treatment modalities and complications rates of the facial trauma attended by the Division of Oral and Maxillofacial Surgery of Piracicaba Dental School ? Unicamp occurred in the region of Piracicaba from April 1999 to March 2004. A to

42. DNA extraction and quantification from touch and scrape preparations obtained from autopsy liver cells
The objective of the present study was to develop a simplified low cost method for the collection and fixation of pediatric autopsy cells and to determine the quantitative and qualitative adequacy of extracted DNA. Touch and scrape preparations of pediatric liver cells were obtained from 15 cadavers at autopsy and fixed in 95% ethanol or 3:1 methanol:acetic

43. Evaluation of malignant lesions of the maxillomandibular complex, on the presence of metallic artifacts using computed tomography. / "Avaliação de lesões malignas dos maxilares na presença de artefatos dentários metálicos utilizando a tomografia computadorizada"
Computed tomography is an important tool to determinate the diagnosis, treatment and follow up malignant lesions of the maxillomandibular complex. In many cases, it is the election exam to all of these purposes. One problem with CT is the artifacts that appear in the presence of metallic restorations, implants and metallic fixation screws or plates. These ar

44. Influência da estimulação ultra-sônica de baixa intensidade no reparo de osteotomias de tíbias com fixação flexível / The influence of low-intensity ultrasound on the tibia osteomy healing of rabbits, with flexible fixation
O ultra-som de baixa intensidade tem demonstrado ser um recurso acelerador do processo de consolidação óssea em fraturas. Este estudo experimental investigou a influência da estimulação ultra-sônica de baixa intensidade no processo de reparo ósseo em fraturas de tíbias tratadas por meio de fixação flexível. O estudo foi desenvolvido no laboratór

45. Male perineal sling with autologous aponeurosis and bone fixation: description of a technical modification
Post-prostatectomy urinary incontinence is an uncommon complication of adenomectomies, occurring in approximately 1% of cases and being more frequent following radical prostatectomies. There is a significant implication in the quality of life for these patients. The surgical techniques employed for its treatment are the implantation of an artificial sphincte

46. Evaluation of tissue response due to different fixation materials in autogenous bone grafts: microscopic morphological analysis / Avaliação da resposta tecidual frente a diferentes materiais de fixação em enxertos ósseos autógenos: análise microscópica morfológica
Autogenous bone grafts have been largely used for the reconstruction of severely atrophic ridges. The fixation of these grafts plays an important role in bone graft repair, leading to the integration to the receptor bed and early revascularization. Resorbable plates and screws are being developed in an attempt to minimize some negative aspects of the metalli

47. Efeito do tratamento com fatores hepatotróficos sobre o fígado de ratas (Wistar) com fibrose induzida experimentalmente / Effect of the treatment with hepatotrophic factors on the liver of rats (Wistar) with experimentally induced-fibrosis
The extraordinary capacity of growth of hepatic tissue can be stimulated by two processes, by the partial hepatectomy or by hepatotrophic substance supply. In this work, it was adopted the second option to treat rats with induced-fibrosis, verifying the effect of the hepatotrophic factors on the histopathological evaluation, the ratio volumetric of the colla

48. Bioactive Hierarchical Structures for Genetic Control of Bone Morphogenesis
For thirty years it has been known that certain compositions of Na2O-CaO-P2O5-SiO 2 glasses will form a mechanically strong, chemical bond to bone. These materials have become known as bioactive glasses and the process of bonding is called bioactive fixation. Bioactive glasses are widely used clinically in the repair of bone defects. Recent research at the I
