We employed 1,1-diphenyl-2-picrylhydrazyl hydrate (DPPH)- and 5,5-dimethyl-1-pyrroline-N-oxide (DMPO)-electron spin resonance (ESR) to study the effects of suppression of reactive oxygen species (ROS) by eight selected coumarin derivatives under oxidative conditions. Esculetin was the most potent radical scavenger among the eight tested compounds. Our(More)
AIM Acute pancreatitis (AP) is a process with variable involvement of regional tissues or organ systems. Multifactorial scales included the Ranson, Acute Physiology and Chronic Health Evaluation (APACHE II) systems and Balthazar computed tomography severity index (CTSI). The purpose of this review study was to assess the accuracy of CTSI, Ranson score, and(More)
OBJECTIVES To perform risk stratification by serum adipocytokines and serum markers of extracellular matrix in heart failure patients with high b-type natriuretic peptide (BNP). METHODS Patients with heart failure were enrolled in this study. Serum adipocytokines and serum markers of extracellular matrix were analyzed. RESULTS In total, 131 patients(More)
We report a case of gastrointestinal stromal tumor (GIST) of the prostate in a 75-year-old man with dysuria and urinary retention. Digital rectal examination revealed a markedly enlarged prostate. The serum level of prostate-specific antigen was 0.2 ng/dL. Imaging studies showed an expanded prostate, measuring 6.7 x 5.6 x 5.5 cm, with heterogeneity in(More)
Far infrared (FIR) rays are used for many therapeutic purposes, but the intracellular mechanisms of their beneficial effects have not been entirely elucidated. The purposes of this study were thus to explore the effects of ceramic-generated far infrared ray (cFIR) on RAW 264.7 cells by determining the scavenging activity of hydrogen peroxide (H2O2), cell(More)
The 5-HT1B receptor has been implicated in several psychiatric disorders and is a potential pharmacological target in the treatment of depression. Here we report the synthesis of a novel PET radioligand, [11C]AZ10419369 (5-methyl-8-(4-methyl-piperazin-1-yl)-4-oxo-4H-chromene-2-carboxylic acid (4-morpholin-4-yl-phenyl)-amide), for in vivo visualization of(More)
The neurotransmitter glutamate is the primary excitatory neurotransmitter in mammalian brain and is responsible for most corticocortical and corticofugal neurotransmission. Disturbances in glutamatergic function have been implicated in the pathophysiology of several neuropsychiatric disorders-including schizophrenia, drug abuse and addiction, autism, and(More)
Sulforaphane (SFN) has been indicated for the prevention and suppression of tumorigenesis in solid tumors. Herein, we evaluated SFN's effects on imatinib (IM)-resistant leukemia stem cells (LSCs). CD34(+)/CD38(-) and CD34(+)/CD38(+) LSCs were isolated from KU812 cell line flowcytometrically. Isolated LSCs showed high expression of Oct4, CD133, β-catenin,(More)
Lymphangioma is a benign tumor, which is a consequence of lymphatic malformation with blockage of lymphatic flow. Most lymphangiomas occur in the neck and axillary region, and < 1% occur in the mesentery or retroperitoneum. Lymphangiomas arising from the pancreas are extremely rare. We report the case of a 34-year-old woman with cystic lymphangioma of the(More)
BACKGROUND/PURPOSE The influence of home- and clinic-based caring system on the economic burden of heart failure remains unknown. METHODS Between January 2004 and December 2004, chronic heart failure patients who were followed up by specialist nurse-led telephone visiting regularly were enrolled. Clinical and economic data half a year before enrollment(More)
