Tumores das glândulas salivares

OBJECTIVO: Descrever e ilustrar as características ecográficas e tomodensitométricas dos tumores das glândulas salivares, salientando a diferenciação radiológica entre tumores benignos e malignos e a sua correlação anátomo-patológica, terapêutica e prognóstica. MATERIAL E MÉTODOS: Estudo retrospectivo, com revisão das imagens de ecografia e TC, dos tumores das glândulas salivares diagnosticados no nosso Hospita...

Mesenchymal hamartoma of the liver: a case report and literature review.

We report a case of a mesenchymal hamartoma of the liver in a two-year-old boy. He presented to the emergency room with abdominal distention and vomiting. Abdominal ultrasound and computed tomography were performed and revealed a large, intra-peritoneal lesion, with thick wall, multiple cysts of variable size and solid septa. The lesion was surgically resected. Pathological examination revealed a mesenchymal ha...

q-exponential distribution in time correlation function of water hydrogen bonds

In a series of molecular dynamics simulations we analyzed structural and dynamics properties of water at different temperatures (213 K to 360 K), using the Simple Point Charge-Extended (SPC/E) water. We detected a q-exponential behavior in the history-dependent bond correlation function of hydrogen bonds. We found that q increases with T -1 below approximately 300 K and is correlated to the increase of the tetr...
