PURPOSE To assess whether measuring the pattern of pancreatic enhancement on gadolinium chelate dynamic magnetic resonance imaging (MRI) is helpful for diagnosis of suspected early or mild chronic pancreatitis. MATERIALS AND METHODS In this retrospective study, 24 patients with suspected early or mild chronic pancreatitis, classified by imaging criteria(More)
OBJECTIVES To evaluate the outcome of arterially enhancing nodules (AENs) measuring <20 mm detected on MRI in patients with cirrhosis. METHODS Prospective analysis of 54 patients with a total of 161 AENs <20 mm on MRI. Inclusion criteria included a minimum of 12 months of MRI follow-up or histological evaluation of the AEN. Key exclusions were patients(More)
Accumulating evidence suggests that an imbalance in T-helper type 1 (Th1)/Th2 response with enhanced Th1 immune response has an important role in the process of coronary artery disease (CAD). Dendritic cell (DC) subsets, myeloid DCs (mDCs) and plasmacytoid DCs (pDCs), could regulate immune reactions by polarizing naive T-helper cells into Th1 or Th2(More)
BACKGROUND It has been shown that dendritic cells (DCs) and fractalkine play a role in accelerating progression of the inflamed atherosclerotic lesions and plaque rupture. We evaluated the numbers and functional changes of DCs and its subsets in human type 2 diabetes with or without unstable angina pectoris (UAP). METHODS The study population consisted of(More)
OBJECTIVE To study the MR appearance of lymph nodes in relation to activity of chronic active hepatitis C, we correlated the findings on MR imaging with a histologic grading of the activity level. MATERIALS AND METHODS Fifty patients with chronic active hepatitis C, who had MR imaging examinations and a related histology report from a liver biopsy(More)
OBJECTIVE Our purpose was to determine the association between posterior lumbar spine subcutaneous edema, fluid collections, and body weight on lumbar spine MR imaging. MATERIALS AND METHODS MR images of the lumbar spine obtained at 1.5 T of 307 consecutive outpatients (191 female, 116 male) were reviewed on the basis of MR imaging signal characteristics(More)
In this paper, we report on the design, fabrication and subsequent investigation of a broad band cross polarization converter based on a C2-symmetric ring/disk cavity. Different plasmon hybridization modes are excited in the ring/disk cavity and enable the polarization manipulations. The designed cross polarization converter can convert the x or y polarized(More)
In this article, a multi-band plasmonic filter based on double layer spoof surface plasmon polaritons was presented. The multi-band performance resulted from the high-order modes of the spoof surface plasmon polaritons (SSPPs), which has been verified through the dispersion curves and surface electric fields. The cutoff frequency of each band of the filter(More)
This paper presents a rotor flux estimation method for induction motors based on high-order terminal sliding-mode observer. A terminal sliding mode manifold is designed for the observer and a control strategy is applied to stabilize the observer. A high-order sliding-mode mechanism is utilized in the observer controller to generate a smooth control signal,(More)
Saccharides have been recognized as potential bio-lubricants because of their good hydration ability. However, the interfacial structures of saccharides and their derivatives are rarely studied and the molecular details of interaction mechanisms have not been well understood. In this paper, the supramolecular assembly structures of saccharic acids(More)
