BACKGROUND High-definition (HD) positron emission tomography (PET) image reconstruction is a new image reconstruction method based on the point spread function system, which improves the spatial resolution of the images. PURPOSE To compare the utility of HD reconstruction of PET images for staging lung cancer with that of conventional 2D ordered subset(More)
We have isolated a new gene, psu1(+), from the fission yeast Schizosaccharomyces pombe. The predicted amino acid sequences shows that this protein has striking homology to the SUN family of the budding yeast, hence designated Psu1 (S. pombe homologue of the SUN family). Disruption of the psu1(+) gene revealed that it is essential for growth, and the null(More)
Hypothemycin was originally isolated as an antifungal metabolite of Hypomyces trichothecoides. Here we report that treatment on v-K-ras-transformed NIH3T3 cells (DT cells) with hypothemycin caused drastic decrease in amount of cyclin D1 protein with concomitant prolongation of G1 phase in their cell cycle. Analysis using hypothemycin-resistant mutant of(More)
