27. Avaliação da expressão do vírus de Epstein-Barr e metaloproteinase 9 nas células de Hodgkin-Reed-Sternberg e correlação com os parâmetros clínicos e evolutivos em pacientes com Linfoma de Hodgkin clássico no Brasil / Matrix Metalloproteinase-9 is consistently expressed in Hodgkin-Reed-Sternberg cells and has no impact on survival in patients with Epstein-Barr virus (EBV) related and non-related Hodgkin lymphoma in Brazil
Clinical and histological features of classical Hodgkin lymphoma (cHL) are primarily due to the effects of cytokines, enzymes and chemokines produced by Hodgkin-Reed-Sternberg (HRS) cells and their surrounding inflammatory cells in response to signals triggered by etiological factors such as Epstein-Barr virus (EBV). Matrix metalloproteinase-9 (MMP-9) has be

31. Regulation of negative emotions in high trait anxious individuals: an ERP study
Literature has shown that failures in the ability to down-regulate negative emotions are the core substrate of anxiety disorders. Previous studies have investigated this issue by encouraging individuals to voluntarily change how they think about a situation in order to decrease its emotional impact. The majority of studies has demonstrated that explicit inst
