The distribution of neutral and sialyl N-linked oligosaccharides from human serum glycoproteins has been studied using three kinds of HPLC columns as described below. N-linked oligosaccharides were released from chymotrypsin- and trypsin-digested glycopeptides of human serum by means of glycoamidase (from almond) digestion. The reducing ends of the(More)
OBJECTIVES To clarify the causes of death of residents with renal tubular dysfunction induced by cadmium (Cd) in the environment. METHODS A 15 year follow up study was performed with the inhabitants living in the Cd polluted Kakehashi River basin in Japan. Standardised mortality ratios (SMRs) for causes of death, classified by ICD-9, were computed using(More)
In this study we have attempted to quantify the thermal and photoperiodical responses of rice (Oryza sativa L.) flowering time QTLs jointly by a 'date-of-planting' field experiment of a mapping population, and a 'phenological model' analysis that separately parameterizes the two responses, based on daily temperature, daily photoperiod and flowering date.(More)
The functions of src family protein-tyrosine kinases are thought to be regulated negatively by the phosphorylation of highly conserved tyrosine residues close to their carboxyl termini. Recently we have purified and cloned a protein-tyrosine kinase (designated as CSK) that can specifically phosphorylate the negative regulatory site of p60c-src. To elucidate(More)
PURPOSE We measured the time lags between the start or end of tasks and signal changes in functional MRI (fMRI) for various age groups and evaluated the age correlation of the time lags. METHODS Forty subjects, 20-76 years old, were evaluated. fMRI was performed with and echo planar imaging sequence at 0.5 s intervals. We measured the time for the signal(More)
Using an expression cloning strategy, the cDNA encoding the human HNK-1 sulfotransferase (HNK-1ST) has been cloned. During this cloning we found that HNK-1ST and other Golgi-associated sulfotransferases cloned before share homologous sequences including the RDP motif (Ong, E., Yeh, J.-C., Ding, Y., Hindsgaul, O., and Fukuda, M. (1998) J. Biol. Chem. 223,(More)
When people are completely isolated from environmental time cues, their circadian rhythms free run with a nearly 24-h cycle, generated by an internal body clock. Free-running temperature, cortisol, and melatonin rhythms have also been described in totally blind people, even though they were living in normal society and had access to abundant time cues; thus(More)
We propose a three-dimensional (3-D) sugar-mapping technique for pyridylaminated (PA) neutral and sialyl oligosaccharides as a powerful structural characterization of N-linked oligosaccharides using only picomoles of samples. The new map consists of the elution data from 42 different sialyl oligosaccharides, 26 of which are mono-, 7 of which are di-, 7 of(More)
BACKGROUND AND PURPOSE Visual field defects sometimes occur after temporal resection surgery. Our purpose was to evaluate the correlation between visual field defects caused by temporal lobe resection and the degree of resection of the Meyer loop, as assessed by diffusion tensor tractography. MATERIALS AND METHODS We examined 14 patients who underwent(More)
We isolated a novel gene, APCL, that showed significant homology to the adenomatous polyposis coli (APC) tumor suppressor gene. This novel gene, located on chromosome 19p13.3, encodes a protein of 2303 amino acids that is expressed specifically in the brain. The predicted protein of APCL contains five copies of a 20-amino-acid motif (FXVEXTPXCFSRXSSLSSLS).(More)
