Dyschromatosis symmetrica hereditaria (DSH) (also called "reticulate acropigmentation of Dohi") is a pigmentary genodermatosis of autosomal dominant inheritance characterized by a mixture of hyperpigmented and hypopigmented macules distributed on the dorsal aspects of the hands and feet. To determine the gene responsible for this disease, we performed a(More)
Inorganic arsenic is converted to methylated metabolites, and most is excreted in urine as dimethylarsinic acid in humans and animals. The present study was conducted to investigate the metabolism of arsenic and identify hepatic and renal metabolites of arsenic after an intravenous injection of arsenite (0.5 mg As/kg body weight) in rats. Similar levels of(More)
The correlation between mutations in the Werner’s syndrome (WRN) gene and the haplotypes of surrounding markers was studied in Japanese patients. We have elucidated the genomic structure of WRN helicase, and found five additional mutations, designated mutations 6–10. Mutations 4 and 6 were found to be the two major mutations in this population; these(More)
Dyschromatosis symmetrica hereditaria (DSH) is a pigmentary genodermatosis of autosomal-dominant inheritance. We have reported 20 different mutations of the adenosine deaminase acting on RNA 1 gene (ADAR1) in patients with DSH since we had clarified that the disease is caused by a mutation of the ADAR1 gene in 2003. In this study, we report 10 novel(More)
To determine the significance of poultry and bovine as infectious sources of Campylobacter jejuni in Japan, the serotype distribution and pulsed-field gel electrophoresis (PFGE) patterns of poultry and bovine isolates were compared with those of isolates from patients with diarrhea in Akita (Japan). Serotypes O:2 and O:4-complex were common in human,(More)
Four bla(VIM-2) gene-harboring Pseudomonas aeruginosa strains were identified. These strains possessed a class 1 integron harboring ORF1, bla(VIM-2), and aacA4 gene cassettes. The transposon-mediated horizontal spread of the bla(VIM-2) gene among these strains was suggested, which increases the threat that the bla(VIM-2) gene will disseminate among diverse(More)
The profile of helicase gene mutations was studied in 89 Japanese Werner’s syndrome (WRN) patients by examining the previously described mutations 1– 4 as well as a new mutation found during this study, designated mutation 5. Of 178 chromosomes (89 patients), 89 chromosomes (50%) had mutation 4, 11 (6.2%) chromosomes had mutation 1, and two chromosomes(More)
BACKGROUND We conducted a case-control study to examine the impact of coronal heart disease (CHD) risk factors on calcium oxalate (CaOX) stone formation. METHODS Variables included body mass index (BMI), current alcohol use, smoking habit, hypertension, hypercholesterolemia, diabetes mellitus, and hyperuricemia. Data suf fi cient for analysis were(More)
The lyase activity toward Se-methylated selenoamino acids and the demethylase activity toward methylselenol in the metabolism of selenium were characterized in vitro. The beta- and gamma-lyase activities toward selenomethionine (SeMet) and Se-methylselenocysteine (MeSeCys), respectively, were compared under exactly identical conditions by incubating(More)
OBJECTIVES Although several nomograms for prostate cancer detection have been developed for Western populations, the models constructed on Japanese data would be more useful for the Japanese population because of various differences between Western and Asian populations. We previously developed a model for predicting the probability of a positive initial(More)
