It is known that light-box luminance is an important factor in the detection of objects on radiographs. Existing methods for image contrast enhancement do not consider the luminance effect so that the enhancement may be inappropriate for the processed image displayed on a video monitor. Based on the properties of human visual system (HVS), an adaptive local(More)
Hibiscus protocatechuic acid (PCA), a phenolic compound isolated from the dried flower of Hibiscus sabdariffa L. (Malvaceae), demonstrated antioxidant and antitumor promotion effects in our previous study. In the present study, Hibiscus PCA was found to inhibit the survival of human promyelocytic leukemia HL-60 cells in a concentration- and time-dependent(More)
BACKGROUND Multidisciplinary care is advocated as an effective chronic kidney disease treatment program in a few, but not all, studies. Our study aimed to evaluate the effect of multidisciplinary care on renal outcome and patient survival using a larger cohort. METHOD A total 1382 chronic kidney disease patients, ages 18-80 years, with chronic kidney(More)
OBJECTIVE The purpose of this study was to compare quality of life (QOL) between peritoneal dialysis (PD) patients with adequate and inadequate total solute clearance (TSC). We also tried to determine the relationship between QOL and TSC. DESIGN A cross-sectional study design was used in which QOL was evaluated and compared between PD patients with(More)
BACKGROUND Many studies support the role of bilirubin as a cytoprotector in chronic inflammatory diseases, such as stroke and atherosclerosis. AIM To investigate the relationship between serum total bilirubin levels and functional dependence in older adults. METHODS Data from the National Health and Nutrition Examination Survey (1999-2002) pertaining to(More)
In this study, three Chinese patients with ticlopidine-induced aplastic anemia were reported and another 13 patients in the English literature were reviewed. We attempted to find underlying similarities, evaluate the risk factors, and identify appropriate treatment for this complication. All but one of the patients were over 60 years old, and the 6 who died(More)
A new configuration for a pressure sensor in which the motion of a diaphragm produces strain in a fiber Fabry-Perot interferometer (FFPI) is described. The single-mode fiber containing the interferometer is bonded at one end to the stainless-steel diaphragm. The fiber is also attached beyond the interferometer to the sensor housing in such a manner that it(More)
Histoplasmosis is one of the most common opportunistic fungal infections in immunocompromised patients in endemic areas. We report the first two microbiologically documented cases of histoplasmosis in Taiwan. The first patient, with acquired immunodeficiency syndrome and a depleted CD4+ lymphocyte count, presented with a history of prolonged fever, papular(More)
While K-means is one of the most well known methods to partition data set into clusters, it still has a problem when clusters are of different size and different density. K-means converges to one of many local minima. Many methods have been proposed to overcome these limitations of K-means, but most of these methods do not overcome the limitation of both(More)
The study was designed to determine whether hemodialysis patients in Taiwan had a different antibody response to common virus infections compared to the normal population. Serum samples from 18 hemodialysis patients and 21 healthy volunteers were obtained every 3 months for 2 years. Geometric mean titers (GMTs) of immunoglobulin G (IgG) antibodies to(More)
