To investigate the effects of iterative reconstruction in 18F-fluorodeoxyglucose (FDG) gamma camera coincidence imaging (GCI), image contrast and visual detection obtained by using the iterative ordered-subsets expectation maximization (OSEM) reconstruction, in a phantom and in patients with lung cancer and breast cancer, were compared with those obtained(More)
The effect of summer climate on leaf carbon isotope composition (δ13C) of the major roadside tree species Prunus × yedoensis (P. yedoensis) was investigated in Kyoto city, Japan, to explore the implications for alterations in urban environments. Temperature and the vapor pressure deficit were higher at sites of higher traffic volumes, possibly affected by a(More)
The evaluation of hemodialysis ultrafiltrate is essential for the assessment of uremic toxins, dialyzer net performance, protein catabolic rate, and safety and environmental protection. Total dialysate collection (TDC), however, is technically far from the daily procedure used. In the present study, use of a continuous syringe extraction method (CSEM) as a(More)
BACKGROUND The detection rate of multiple lung adenocarcinomas, which display multiple ground glass opacity nodules in the peripheral lung, is increasing because of advances in high resolution computed tomography. The genetic backgrounds of multiple nodules and the mechanisms that underlie their multicentric development are unknown. In this study, we(More)
The objective of this study was to evaluate transcriptional expression of survivin and the two splice variants (survivin-2B and survivin-DeltaEx3) in cervical carcinomas. The gene expression levels of survivin and its splice variants in 11 human cervical carcinoma cell lines and 20 malignant and 12 normal cervical tissue samples were analyzed using(More)
UNLABELLED This study investigated the validity of myocardial 18F-fluorodeoxyglucose (FDG) imaging with a dual-head gamma camera operated in coincidence detection mode (DCD-I) by comparing this technique with conventional PET and SPECT with ultra-high-energy general-purpose collimators (UHGPs). METHODS The subjects included 5 healthy volunteers and 20(More)
Lung adenocarcinoma has never before been reported to be associated with von Hippel-Lindau (VHL) disease. Here, we report a case of VHL disease in a patient who had metachronous multiple lung adenocarcinomas. The patient is a 64-year-old-woman with VHL disease. She underwent surgical resection of one adenocarcinoma and one atypical adenomatous hyperplasia.(More)
A 55-year-old female felt a transient chest pain soon after a fish meal. Sixteen days later she presented a local clinic with fever of 38°C. After chest computed tomography( CT) and upper gastrointestinal endoscopy showed fish bone embedded in the wall of the middle portion of the esophagus, she referred to our hospital 22 days after the meal. Thirty days(More)
The conventional protocol for whole-body positron emission tomography (PET) with fluorine-18 fluorodeoxyglucose (FDG) requires a total acquisition time of 40-60 min, which is inconvenient for many oncological patients owing to fatigue and discomfort. This study examined the feasibility of a short protocol for whole-body PET. A phantom containing six "hot"(More)
Free full-thickness grafts of nail bed of the lesser toes or an amputated fingertip were successfully performed on 11 fingers of 10 patients since 1979. In nine patients in whom the nail beds had been severely crushed or lost, but the nail matrix was intact, the end results of this technique were excellent. In one patient in whom both the nail bed and(More)
