PURPOSE Autophagy consists of lysosome-dependent degradation of cytoplasmic contents sequestered by autophagic vesicles (AV). The role of autophagy in determining tumor aggressiveness and response to therapy in melanoma was investigated in this study. EXPERIMENTAL DESIGN Autophagy was measured in tumor biopsies obtained from metastatic melanoma patients enrolled on a phase II trial of temozol...

OBJECTIVE To evaluate the impact of an aggressive treatment approach using muscle flaps or omentopexy in infections of the sternum and anterior mediastinum following sternotomy on mortality, as compared to that of a conservative treatment approach. METHODS Data were collected prior to, during and after the surgical procedures. Group A (n = 44) included patients submitted to conservative treat...

Aggressive angiomyxoma is an uncommon mesenchymal myxoid tumor that is characterized by slow growth and frequent local recurrence. It is currently regarded as a nonmetastasizing tumor. We describe a case of recurrent aggressive angiomyxoma with invasion into the veins including the inferior vena cava and the right atrium and with pulmonary metastases. Our case, together with those unusual cases...

Transformation is the evolution of an indolent lymphoma/leukemia to an aggressive lymphoma, typically harboring a very poor prognosis. This phenomenon is well described in humans, but underestimated in dogs although recognized as a possible evolution of indolent lymphomas/leukemias. In canine chronic leukemias, blast crisis (mainly in myeloid) and Richter syndrome (transformation into a high gr...

Aggressive angiomyxoma (AAM) is a rare benign mesenchymal tumor that occurs almost exclusively in the soft tissues of the pelvis and perineum. Very few cases of AAM occurring outside these regions have been reported. The present report presents a case of AAM originating from the liver of a 50-year-old female patient. Tumor resection was performed, and pathological examination revealed microscop...

The distinction between proactive and reactive functions of aggression is one of the most common divisions when investigating aggression among children and adolescents. To date, self-report is the least used measurement, despite existing literature supporting the view that the best informant regarding internal processes and motives are children themselves. The main aim of this study was to exam...
