Objectives: To verify the incidence of calcified brain metastases (CBM), illustrating the different presentation patterns and histology of primary tumor. Methods: A series of 1002 consecutive brain computed tomography (CT) scans of patients with known primary tumors was retrospectively assessed. CBM were defined by the presence of calcification...

Background: Osteoblastoma is a benign bone-forming tumor, sometimes locally invasive, that may involve any bone. The highest incidence is between 20 and 30 years of age, and there are no cases described in the elderly. Methods: We report a case of an elderly patient with a lesion in the lumbar spine in which osteoblastoma diagnosis was made....

OBJECTIVE: Somatostatin is an endogenous inhibitor of hormone secretion and cell proliferation. Treatment with somatostatin analogues in humans causes a reduction in size and secretory activity of endocrine tumours, including GH-secreting pituitary adenomas. This study was aimed to characterize the intracellular mechanisms mediating the in...

We have recently reported that glioblastoma (GB)-initiating cells (GIC) with low expression and/or mutation of TP53 and high expression of PI3K ("responder" genetic profile) can be effectively and safely radiosensitized by the ATM inhibitor KU60019. We report here on drug's diffusion and elimination from the animal body and brain, its effects...

Background: B cell receptor Immunoglobulin (BcR IG) repertoire of Chronic Lymphocytic Leukemia (CLL) is characterized by the expression of quasi-identical BcR IG. These are observed in approximately 30% of patients, defined as stereotyped receptors and subdivided into subsets based on specific VH CDR3 aa motifs and phylogenetically related IGHV...
