Cancer induced bone pain (CIBP) is a major clinical problem. Although opioids remain the principal axis in drug therapies for CIBP, their sustained application is known to induce cellular and molecular adaptations including enhanced neuroimmune reactivity. This is generally characterized by glial activation and proinflammatory cytokine production which(More)
BACKGROUND The aim of this study is to investigate the relationship between 16-slice spiral CT perfusion imaging and tumor angiogenesis and VEGF (vascular endothelial growth factor) expression in patients with benign and malignant pulmonary nodules, and differential diagnosis between benign and malignant pulmonary nodules. METHODS Sixty-four patients with(More)
– It is pointed out in this paper that a more appropriate description of the joint target tracking and classification (JTC) problem would be the simultaneous probability density functions (pdfs) of target state and target class instead of the joint target state-class pdf. In this paper, models of different classes are combined into a unified set. The(More)
BACKGROUND AND OBJECTIVES We hypothesized that continuous right thoracic paravertebral block, following bolus initiation, decreases opioid consumption after right-lobe hepatectomy in patients receiving patient-controlled intravenous analgesia with sufentanil. METHODS Patients undergoing right-lobe hepatectomy with a right thoracic paravertebral catheter(More)
Previous functional magnetic resonance imaging (fMRI) studies have identified activation in the prefrontal-parietal-sub-cortical circuit during feigned memory impairment when comparing with truthful telling. Here, we used fMRI to determine whether neural activity can differentiate between answering correctly, answering randomly, answering incorrectly, and(More)
