BACKGROUND NAD(P)H:quinone oxidoreductase 1 (NQO1) C609T was reportedly associated with leukemia, lung cancer, colorectal cancer, and urological malignancies. This study was conducted to screen possible cancer sites associated with this polymorphism by a prevalent case-control design. METHODS The cases were 102 patients with esophageal cancer, 143 with(More)
PURPOSE The correlation between the DNA content, determined using fresh tumor tissues, and the macroscopic presentation of the lesion was studied prospectively in patients with T1 glottic carcinoma. METHODS AND MATERIALS DNA flow cytometry and fiber-optic endoscopic examination were performed for 30 previously untreated patients with T1 glottic carcinoma.(More)
A new strain isolated from soil utilizes cyclopropanecarboxylate as the sole source of carbon and energy and was identified as Rhodococcus rhodochrous (H. Nishihara, Y. Ochi, H. Nakano, M. Ando, and T. Toraya, J. Ferment. Bioeng. 80:400-402, 1995). A novel pathway for the utilization of cyclopropanecarboxylate, a highly strained compound, by this bacterium(More)
Open networks can be used for many purposes, for example, e-commerce, e-government, and so on. Different from those conventional applications, we consider networked collaborative activities, for example networked research activities. This application might be very useful and research activities could be significantly promoted. However, we must solve many(More)
