As the expression of CD57 is indicative of immunosuppression, it may constitute a negative immunomodulator of RC's epithelium growth. Further studies are necessary to understand the importance of this cell to the biological activity or inactivity of RC's epithelium development.

BackgroundThis study compared the immunohistochemical expression of ki-67, transforming growth factor beta 1 (TGF-β1) and intercellular adhesion molecule-1 (ICAM-1) in inflammatory periapical cysts and residual cysts.Material and MethodsThe study sample was composed by 25 periapical cysts and 25 residual cysts and immunohistochemical reactions were carried out using antibodies directed against ICAM-1, TGF-β1 and ki-67. Clinical, radiological, gross, histological and immunohistochemical data were tabulated for descriptive and comparative analysis using the SPSS software and differences were considered statistically significant when p<0.05%.ResultsThere were no differences between the expression of ICAM-1 (p=0.239) and TGF-β1 (p=0.258) when comparing both groups. Ki-67 labeling index was higher in residual cysts compared to periapical cysts (p=0.017).ConclusionsResults from the present study suggest that some specific inflammatory stimuli on residual cysts would modulate their mechanisms of etiopathogenesis, growing and repair. Key words:Periapical cyst, radicular cyst, residual cyst, transforming growth factor beta 1 (TGF-β1), intercellular adhesion molecule 1 (ICAM-1), ki-67.

Large-scale testing and evaluation of network solutions are complex and typically involve multiple domains (e.g., optical, wireless, and cloud). The FUTEBOL project has deployed geographically distributed testbeds in Brazil and Europe that enable the experimentation and validation of new cross-domain network solutions. In this article, we introduce a Control Framework that allows experimenters to slice, reserve, and orchestrate optical, wireless, and cloud resources in a coordinated manner. We illustrate the features of our Control Framework and evaluate it through an experiment involving resource orchestration and automatic service scaling across multiple domains.
