Chalcone synthase (CHS) is the key enzyme in an early stage of the flavonoid biosynthetic pathway. In the present study, a full-length cDNA clone for CHS was isolated from flower tepals of the liliaceous ornamental Tricyrtis sp., in which tepals have many reddish-purple spots resulting from accumulation of cyanidin derivatives. The deduced amino acid(More)
The J-Linac portion of the KEK electron-positron (e-/e +) Linac is currently under construction (1994-1998); its addition will improve and reinforce the accelerator control system. Until now, the operation of the 2.5 GeV PF Linac, particularly its routine operation, has been contracted to a private company. Recently, a survey using questionnaires was(More)
Neuropsychiatric systemic lupus erythematosus (NPSLE) is speculated to be caused by disturbed microcirculation of the central nervous system. However, characteristic imaging findings of NPSLE have not been established. Hence, we investigated whether high-resolution images obtained using ultrahigh field MRI at 7 T can detect microcerebrovascular lesions in(More)
BACKGROUND Antigen presenting cells play a pivotal role in the adaptive immune response in hypersensitivity pneumonitis (HP). It was hypothesised that lymphangiogenesis is involved in the pathophysiology of HP via cell transport. OBJECTIVE To determine the clinical significance of lymphangiogenic factors in HP. METHODS Levels of vascular endothelial(More)
The KEK 8GeV Linac (linear accelerator) has been using an operation database consisting of PCs (personal computers) and MS-SQL [1] on a Windows NT server. An automatic database logging system for Linac operation and attendant problems has been completed. The Linac has both static and dynamic databases, which store accelerator data, a troubleshooting log and(More)
