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)
The ultrasound-guided transversus abdominis plane block and ilioinguinal-iliohypogastric nerve block have been shown to provide pain relief after abdominal surgery. A combination of the 2 blocks may provide acceptable surgical anesthesia for cesarean delivery. We describe 4 women who had contraindications to neuraxial anesthesia, who underwent cesarean(More)
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)
Despite advances in postoperative pain management, the proportion of patients with moderate to severe postoperative pain is still ranging 20-80%. In this retrospective study, we investigated 1736 patients to determine the incidence of postoperative pain in need of intervention (PPINI)defined as numeric rating scale >4 at rest in the post anaesthesia care(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)
Tropical cyclones have been hypothesized to influence climate by pumping heat into the ocean, but a direct measure of this warming effect is still lacking. We quantified cyclone-induced ocean warming by directly monitoring the thermal expansion of water in the wake of cyclones, using satellite-based sea surface height data that provide a unique way of(More)
23 24 Interannual-decadal variability of tropical cyclone (TC) track density over the North 25 Atlantic (NA) between 1979 and 2008 is studied using observations and simulations with 26 a 25-km-resolution version of the High Resolution Atmospheric Model (HiRAM) forced 27 by observed sea surface temperatures (SSTs). The variability on decadal and interannual(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)
