background: very few studies have utilized specific criteria to assess mental disorders in brain tumor patients. this study aimed to diagnose mental disorders in this population using dsm-iv (depression, sleep, and mood) criteria. methods: from march 2007 to july 2009, the surgically treated patients with intracranial neoplasm were included in the study. these patients were examined in an ambul...

the most frequently mutated tumor suppressor gene found in human cancer is p53. in a normal situation, p53 is activated upon the induction of dna damage to either arrest the cell cycle or else induce apoptosis. however, when mutated, p53 is no longer able to properly accomplish these functions. our aim was to investigate p53 protein alteration in cases of basal cell carcinoma (bcc) and compare ...

primary malignant neoplasms of the pericardium are rare and are predominantly mesotheliomas, followed by benign localized fibrous mesothelioma, malignant fibrosarcoma, angiosarcoma and benign and malignant teratomas. 1 this article concerns an atypical presentation of this malignant tumor with symptoms and signs of pericardial effusion. this unusual feature was complete encasement of the heart ...

OBJECTIVES Patients with heart failure have increased circulating levels of tumor necrosis factor (TNF) and TNF receptors. It is not known whether TNF, which is known to blunt beta-adrenergic responsiveness in experimental models, contributes to the loss of heart rate variability in patients with heart failure. Therefore, we examined heart rate variability in relation to circulating levels of T...

Determination of tumor volume in subcutaneously inoculated xenograft models is a standard procedure for clinical and preclinical evaluation of tumor response to treatment. Practitioners frequently use a hands-on caliper method in conjunction with a simplified formula to assess tumor volume. Non-invasive and more precise techniques as investigation by MR or (μ)CT exist but come with various adve...

Pharmacometric models were developed to characterize the relationships between lesion-level tumor metabolic activity, as assessed by the maximum standardized uptake value (SUVmax) obtained on [(18)F]-fluorodeoxyglucose (FDG) positron emission tomography (PET), tumor size, and overall survival (OS) in 66 patients with gastrointestinal stromal tumor (GIST) treated with intermittent sunitinib. An ...

One recent area of cancer research is irreversible electroporation (IRE). Irreversible electroporation is a minimally invasive procedure where needle electrodes are inserted into the body to ablate tumor cells with electricity. The aim of this paper is to investigate how uncertainty in tissue and tumor conductivity propagate into final ablation predictions used for treatment planning. Two dimen...
