The self-incompatibility possessed by Brassica is an intraspecific reproductive barrier by which the stigma rejects self-pollen but accepts non-self-pollen for fertilization. The molecular/biochemical bases of recognition and rejection have been intensively studied. Self-incompatibility in Brassica is sporophytically controlled by the polymorphic S locus.(More)
Aurora family kinases contribute to regulation of mitosis. Using RNA interference in synchronized HeLa cells, we now show that Aurora-A is required for mitotic entry. We found that initial activation of Aurora-A in late G2 phase of the cell cycle is essential for recruitment of the cyclin B1-Cdk1 complex to centrosomes, where it becomes activated and(More)
In Brassica species that exhibit self-incompatibility, two genes, SLG and SRK, at the S locus are involved in the recognition reaction with self and non-self pollen. From a pollen-recessive S29 haplotype of Brassica rapa, both cDNA and genomic DNA clones for these two genes were isolated and characterized. The nucleotide sequence for the S domain of SRK29(More)
Dynamic behavior of leukocytes in the microcirculation of solid tumor tissue was visualized using a fluorescent labeling technique combined with the use of a real-time confocal laser-scanning microscope (CLSM) system. Colon tumor cells (RCN-9) were inoculated into the peritoneal cavity of male Fischer 344 rats. Tumor-free rats were similarly injected with(More)
BACKGROUND The current study was performed to clarify whether the presence of residual carcinoma in situ at ductal resection margins differs prognostically from residual invasive ductal lesions in patients undergoing surgical resection for extrahepatic cholangiocarcinoma. METHODS A retrospective analysis of 84 patients with extrahepatic cholangiocarcinoma(More)
2-Aminophenol 1,6-dioxygenase was purified from the cell extracts of Pseudomonas sp. AP-3 grown on 2-aminophenol. The product from 2-aminophenol by catalysis of the purified enzyme was identified as 2-aminomuconic 6-semialdehyde by gas chromatographic and mass spectrometric analyses. The molecular mass of the native enzyme was 140 kDa based on gel(More)
BACKGROUND Extended radical esophagectomy with three-field lymphadenectomy for patients with thoracic esophageal cancer has been shown to be effective. But even if this operation is performed, some patients still experience relapse of the disease. The purpose of this study was to clarify the pattern and timing of recurrence after extended radical(More)
BACKGROUND Great controversy exists concerning the adequate extent of esophagectomy for cure in patients with esophageal cancer. Extended radical esophagectomy combined with three-field lymphadenectomy has been performed to improve the cure rates for patients with the disease in Japan. The purposes of this study were to assess the mortality and morbidity(More)
BACKGROUND The purpose of this study was to compare the functional utility of intraoperative ultrasonography (IOUS) and cholangiography (IOC) during a laparoscopic cholecystectomy for the treatment of gallstone disease. STUDY DESIGN A prospective study comparing IOUS and IOC was carried out in 65 patients. Intraoperative ultrasonography was conducted(More)
A new aquaporin (AQP10) was identified in human small intestine. This gene encoded a 264-amino-acid protein with high sequence identity with AQP3 (53%), 9 (52%), and 7 (43%). These AQPs constitute one subfamily of AQP family that is differentiated from the other subfamily of AQP (AQP0, 1, 2, 4, 5, 6, and 8) by sequence homology. Ribonuclease protection(More)
