The serum levels of several metabolites are significantly altered in schizophrenia patients. In this study, we performed a targeted analysis of 34 candidate metabolites in schizophrenia patients (n = 25) and compared them with those in age- and gender-matched healthy subjects (n = 27). Orthogonal partial least square-discriminant analysis revealed that(More)
To report the technical results and imaging findings of intranodal lymphangiogram (INL). we studied four patients (three men, one woman) who had persistent chylous leakage despite conservative treatment after esophageal cancer surgery. Their mean age was 68 years (range 61–74 years). The inguinal or femoral lymph node was punctured under ultrasound guidance(More)
PURPOSE To compare radiation exposure of nurses when performing nursing tasks associated with interventional procedures depending on whether or not the nurses called out to the operator before approaching the patient. MATERIALS AND METHODS In a prospective study, 93 interventional radiology procedures were randomly divided into a call group and a no-call(More)
High-performance liquid chromatography-fluorescence detection using a hydrophilic interaction chromatography-mode column (ZIC®-HILIC) was used to determine four kinds of thiol compounds in human serum. Sera were obtained from 34 subjects for this study (17 male subjects aged 22-38 years and 17 female subjects aged 18-38 years). Serum cysteine,(More)
BACKGROUND AND AIM Several reports have described portopulmonary venous anastomosis (PPVA). However, in balloon-occluded retrograde transvenous obliteration (BRTO), attention has not been paid to paradoxical embolism. The objective of this study was to investigate the existence of a right-left shunt due to PPVA when the drainage vein is occluded by a(More)
PURPOSE To determine the correlation of the rate of change of each future remnant liver (FRL) before and after portal vein embolization (PVE), by CT volumetry and Tc-99m galactosyl human serum albumin scintigraphy (GSA scintigraphy). MATERIAL AND METHODS From December 2007 to July 2012, ten patients underwent PVE before hepatic resection. CT volumetry and(More)
Multidrug resistance (MDR) in cancer is known to decrease the therapeutic efficacy of chemotherapy. The effects of irradiation on MDR in cancer cells remain unclear. Tc-99m methoxyisobutylisonitrile (MIBI) exhibits the same ATP-binding cassette (ABC) transporter kinetics as the chemotherapeutic compound doxorubicin. In this study, we investigated the(More)
Histological examination of adequate biopsy specimens is fundamental to the management of patients with malignant lymphoma. Core-needle biopsy with computed tomography potentially provides a better basis for this assessment. Image-guided needle biopsy should be the first procedure performed in the diagnosis of lymphoma, except in easily accessible(More)
BACKGROUND Technetium-99m methoxyisobutylisonitrile (Tc MIBI) is a substrate with the same uptake kinetics as doxorubicin. Multidrug resistance (MDR) is a mechanism that impedes chemotherapy of non-small cell lung cancer (NSCLC). We examined the effect of radiation exposure on MDR in NSCLC and the synergy between an MDR modulator, GG918, and radiation,(More)
Rectal varices occur in 44.5 % of patients with ectopic varices caused by portal hypertension, and 48.6 % of these patients are untreated and followed by observation. However, bleeding occurs in 38 % and shock leading to death in 5 % of such patients. Two patients, an 80-year-old woman undergoing treatment for primary biliary cirrhosis (Child-Pugh class A)(More)
