| 1 | Confirming Stereochemical Structures of Strigolactones Produced by Rice and Tobacco显示文摘主要 strigolactones (SL ) 由米饭生产了(Oryza sativa L。cv。Nipponbare ) 并且烟草(Nicotiana tabacum L。cv。Michinoku 号码 1 ) 被净化,他们的 stereochemical 结构被在 ESILC/MS 和 GCMS 为他们的 NMR 和 CD 数据和保留时间和集体破碎与光学地纯的合成标准作比较决定。从米饭植物的根流出物净化的 SL 是 orobanchol, orobanchyl 醋酸盐,和 ent-2-epi-5-deoxystrigol。除了这些 SL, 7-oxoorobanchyl 醋酸盐并且通常认为三 methoxy-5-deoxystrigol 异构体被最小公倍数 /MS 检测。7-oxoorobanchyl 醋酸盐的生产似乎发生在早生长阶段,当它仅仅在在孵化的第一个星期期间收集的根流出物被检测。烟草的根流出物包含了至少 11 SL,包括其结构尚待被澄清的通常认为的 didehydro-orobanchol 的 solanacol, solanacyl 醋酸盐, orobanchol, ent-2-epi-orobanchol, orobanchyl 醋酸盐, ent-2-epi-orobanchyl 醋酸盐, 5-deoxystrigol, ent-2-epi-5-deoxystrigol,和三异构体。而且,二 sorgolactone 异构体然而并非 sorgolactone 被最小公倍数 /MS 分析作为次要的 SL 检测。注意米饭植物生产了仅仅 orobanchol 类型 SL 是吸引人的,源于 ent-2-epi-5-deoxystrigol,而是 orobanchol 类型和 strigol 类型 SL,源于 5-deoxystrigol 在烟草植物被检测。 | Xiaonan Xie Kaori Yoneyama Takaya Kisugi Kenichi Uchida Seisuke Ito Kohki Akiyama Hideo Hayashi Takao Yokota Takahito Nomura Koichi Yoneyama | 2013 | Molecular Plant2013,6,1: | 9 |
| 2 | Anticancer effect of linalool via cancer-specific hydroxyl radical generation in human colon cancer显示文摘AIM To investigate the anticancer mechanisms of the monoterpenoid alcohol linalool in human colon cancer cells.METHODS The cytotoxic effect of linalool on the human colon cancer cell lines and a human fibroblast cell line was examined using the WST-8 assay. The apoptosisinducing effect of linalool was measured using the terminal deoxynucleotidyl transferase d UTP nickend labeling assay and flow cytometry with Annexin V. Oxidative stress was investigated by staining for diphenyl-1-pyrenylphosphine, which is a cellular lipid peroxidation marker, and electron spin resonance spectroscopy. Sixteen SCID mice xenografted with human cancer cells were randomized into 3 groups for in vivo analysis: control and low-dose and high-dose linalool groups. The control group was administered tap water orally every 3 d. The linalool treatment groups were administered 100 or 200 μg/kg linalool solution orally for the same period. All mice were sacrificed under anesthesia 21 d after tumor inoculation, and tumors and organs were collected for immunohistochemistry using an anti-4-hydroxynonenal antibody. Tumor weights were measured and compared between groups. RESULTS Linalool induced apoptosis of cancer cells in vitro, following the cancer-specific induction of oxidative stress, which was measured based on spontaneous hydroxyl radical production and delayed lipid peroxidation. Mice in the high-dose linalool group exhibited a 55% reduction in mean xenograft tumor weight compared with mice in the control group(P < 0.05). In addition, tumor-specific lipid peroxidation was observed in the in vivo model.CONCLUSION Linalool exhibited an anticancer effect via cancerspecific oxidative stress, and this agent has potential for application in colon cancer therapy. | Kenichi Iwasaki Yun-Wen Zheng Soichiro Murata Hiromu Ito Ken Nakayama Tomohiro Kurokawa Naoki Sano Takeshi Nowatari Myra O Villareal Yumiko N Nagano Hiroko Isoda Hirofumi Matsui Nobuhiro Ohkohchi | 2016 | World Journal of Gastroenterology2016,22,44: | 5 |
| 3 | Serum type Ⅳ collagen level is predictive for esophageal varices in patients with severe alcoholic disease显示文摘AIM: To determine factors predictive for esophageal varices in severe alcoholic disease (SAD). METHODS: Abdominal ultrasonography (US) was performed on 444 patients suffering from alcoholism. Forty-four patients found to have splenomegaly and/ or withering of the right liver lobe were defined as those with SAD. SAD patients were examined by upper gastrointestinal (UGI) endoscopy for the presence of esophageal varices. The existence of esophageal varices was then related to clinical variables. RESULTS: Twenty-five patients (56.8%) had esophageal varices. A univariate analysis revealed a significant difference in age and type Ⅳ collagen levels between patients with and without esophageal varices. A logistic regression analysis identified type Ⅳ collagen as the only independent variable predictive for esophageal varices (P = 0.017). The area under the curve (AUC) for type Ⅳ collagen as determined by the receiver operating characteristic (ROC) for predicting esophageal varices was 0.78. CONCLUSION: This study suggests that the level of type Ⅳ collagen has a high diagnostic accuracy for the detection of esophageal varices in SAD. | Satoshi Mamori Yasuyuki Searashi Masato Matsushima Kenichi Hashimoto Shinichiro Uetake Hiroshi Matsudaira Shuji Ito Hisato Nakajima Hisao Tajiri | 2008 | World Journal of Gastroenterology2008,14,13: | 4 |

| 6 | 帮助, P53,和 Mlh1 蛋白质在的表示内视镜地 resected 区分类型的早胃的癌症显示文摘 AIM: To analyze the expression of the tumor-related proteins in differentiated-type early gastric carcinoma (DEGC) samples. METHODS: Tumor specimens were obtained from 102 patients (75 males and 27 females) who had received an endoscopic tumor resection at Tottori University Hospital between 2007 and 2009. Ninety-one cancer samples corresponded to noninvasive or intramucosal carcinoma according to the Vienna classification system, and 11 samples were submucosal invasive carcinomas. All of the EGCs were histologically differenti- ated carcinomas. All patients were classified as having Helicobacter pylori (H. pylori ) infections by endoscopic atrophic changes or by testing seropositive for H. pylori IgG. All of the samples were histopathologically classified as either tubular or papillary adenocarcinoma according to their structure. The immunohistochemi- cal staining was performed in a blinded manner with respect to the clinical information. Two independent observers evaluated protein expression. All data were statistically analyzed then. RESULTS: The rates of aberrant activation-induced cytidine deaminase (AID) expression and P53 overexpression were both 34.3% in DEGCs. The expression of Mlh1 was lost in 18.6% of DEGCs. Aberrant AID expression was not significantly associated with P53 overexpression in DEGCs. However, AID expression was associated with the severity of mononuclear cell activity in the non-cancerous mucosa adjacent to the tumor (P = 0.064). The rate of P53 expression was significantly greater in flat or depressed tumors than in elevated tumors. The frequency of Mlh1 loss was significantly increased in distal tumors, elevated gross-type tumors, papillary histological-type tumors, and tumors with a severe degree of endoscopic atrophic gastritis (P < 0.05). CONCLUSION: Aberrant AID expression, P53 overexpression, and the loss of Mlh1 were all associated with clinicopathological features and gastric mucosal alterations in DEGCs. The aberrant expression of AID protein may partly contribute to the induction of nuclear P53 expression. | Yohei Takeda Kazuo Yashima Akihiro Hayashi Shuji Sasaki Koichiro Kawaguchi Kenichi Harada Yoshikazu Murawaki Hisao Ito | 2012 | World Journal of Gastrointestinal Oncology2012,4,6: | 2 |

| 8 | Synchronous pancreatic solid pseudopapillary neoplasm and intraductal papillary mucinous neoplasm显示文摘Solid pseudopapillary neoplasm (SPN) is a rare and low-grade malignant pancreatic neoplasm composed of poorly cohesive monomorphic neoplastic cells forming solid and pseudopapillary structures with frequent hemorrhagic-cystic degeneration. Intraductal papillary mucinous neoplasm (IPMN) is a pancreatic exocrine tumor composed of intraductal papillary growth of mucin containing neoplastic cells in the main pancreatic duct or its major branches. In the case presented here, a 53-year-old, Japanese man was found to have multiple cystic lesions and dilatation of the main pancreatic duct in the neck of the pancreas. Histological examination revealed a main-duct and branch-duct type IPMN, of the gastric-type, involving the neck of the pancreas, associated with a 0.5 cm SPN in the caudal side of the IPMN. We diagnosed this case as synchronous SPN and IPMN. As far as we know, only one other case of synchronous SPN and IPMN has been reported. Both the present case and the previously reported case showed abnormal nuclear expression of β-catenin in SPN, whereas IPMN showed no abnormal nuclear expression. These results suggest that β-catenin abnormality is not a common pathogenetic factor of synchronous SPN and IPMN. | Kenichi Hirabayashi Giuseppe Zamboni Hiroyuki Ito Masami Ogawa Yoshiaki Kawaguchi Tomohiro Yamashita Toshio Nakagohri Naoya Nakamura | 2013 | World Journal of Gastroenterology2013,19,21: | 2 |
