A new method for measurement of the turnover rate of aromatic amino acids and related compounds in vivo using stable isotopes was developed. Deuterium-and carbon 13-labeled phenylalanine and deuterium-labeled tryptophan were used as tracers. This method was applied for the analysis of amino acid and amine metabolism in infantile autism. Marked disturbances(More)
Dullard/Ctdnep1 is a member of the serine/threonine phosphatase family of the C-terminal domain of eukaryotic RNA polymerase II. Embryos lacking Dullard activity fail to form primordial germ cells (PGCs). In the mouse, the formation of PGCs is influenced by BMP4 and WNT3 activity. Although Dullard is reputed to negatively regulate BMP receptor function, in(More)
Here, we report the case of a 62-year-old man with neuroblastoma, which is extremely rare in adults. His tumor was resected, but it recurred four months later. Radiotherapy reduced tumor size, and the patient remained in good health three years after surgical tumor removal. The residual tumor and the treatments administered to this patient were evaluated.(More)
To reduce the incidence of surgical site infection (SSI) after radical cystectomy, a new closing method using subcutaneous continuous aspiration drain was developed and compared to the conventional closing method. The new method involved (a) closed aspiration with an indwelling aspiration drain without suture of the subcutaneous fat and (b) covering with(More)
OBJECTIVE Tamsulosin is often administered at a dose of 0.2 mg in Japan, Korea, and elsewhere in Asia, while a dose of 0.4 mg is more common in the West. In order to determine the higher dose might also be appropriate in the North-East Asian setting, we studied whether the effect of increasing the dose to 0.4 mg in Japanese patients who had dysuria(More)
Percutaneous needle biopsy was carried out in 75 patients with various neurological and muscle diseases (myopathies in 7, lower motor neuron diseases in 22, upper motor neuron diseases in 6, and unlocalized or miscellaneous diseases in 13) and its usefulness as a diagnostic procedure was evaluated. The ages of the subjects ranged from 2 months to 35 years,(More)
