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)
Dominant climatic factors controlling the lifetime peak intensity of typhoons are determined from six decades of Pacific typhoon data. We find that upper ocean temperatures in the low-latitude northwestern Pacific (LLNWP) and sea surface temperatures in the central equatorial Pacific control the seasonal average lifetime peak intensity by setting the rate(More)
Numerous electrophysiological studies have showed auditory sensory gating-out abnormalities in chronic schizophrenia with antipsychotic medication. Previous research has used functional magnetic resonance imaging (fMRI) with excellent spatial resolution to identify the neural substrates of sensory gating-out deficits revealing increased hemodynamic response(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)
The insula is a region that integrates interoception and drug urges, but little is known about its role in behavioral addiction such as internet addiction. We investigated insula-based functional connectivity in participants with internet gaming disorder (IGD) and healthy controls (HC) using resting-state functional MRI. The right and left insula subregions(More)
BACKGROUND Paravertebral block is often used to provide postoperative analgesia after renal surgery. In this case-series report, we present our experience with 3 patients in whom percutaneous nephrolithotomy was performed successfully under ultrasound-guided 3-segment lumbar-thoracic paravertebral block. CASE SUMMARY Three patients were scheduled for(More)
Faking memory impairment means normal people complain lots of memory problems without organic damage in forensic assessments. Using alternative forced-choice paradigm, containing digital or autobiographical information, previous neuroimaging studies have indicated that faking memory impairment could cause the activation in the prefrontal and parietal(More)
