4Near-infrared photoimmunotherapy of pancreatic cancer using an indocyanine green-labeled anti-tissue factor antibody显示文摘AIM To investigate near-infrared photoimmunotherapeutic effect mediated by an anti-tissue factor(TF) antibody conjugated to indocyanine green(ICG) in a pancreatic cancer model.METHODS Near-infrared photoimmunotherapy(NIR-PIT) is a highly selective tumor treatment that utilizes an antibody-photosensitizer conjugate administration, followed by NIR light exposure. Anti-TF antibody 1849-ICG conjugate was synthesized by labeling of rat IgG2 b anti-TF monoclonal antibody 1849(anti-TF 1849) to a NIR photosensitizer,ICG. The expression levels of TF in two human pancreatic cancer cell lines were examined by western blotting. Specific binding of the 1849-ICG to TF-expressing BxPC-3 cells was examined by fluorescence microscopy. NIR-PITinduced cell death was determined by cell viability imaging assay. In vivo longitudinal fluorescence imaging was used to explore the accumulation of 1849-ICG conjugate in xenograft tumors. To examine the effect of NIRPIT, tumor-bearing mice were separated into 5 groups:(1) 100 μg of 1849-ICG i.v. administration followed by NIR light exposure(50 J/cm2) on two consecutive days(Days 1 and 2);(2) NIR light exposure(50 J/cm2) only on two consecutive days(Days 1 and 2);(3) 100 μg of 1849-ICG i.v. administration;(4) 100 μg of unlabeled antiTF 1849 i.v. administration; and(5) the untreated control. Semiweekly tumor volume measurements, accompanied with histological and immunohistochemical(IHC) analyses of tumors, were performed 3 d after the 2nd irradiation with NIR light to monitor the effect of treatments. RESULTS High TF expression in BxPC-3 cells was observed via western blot analysis, concordant with the observed preferential binding with intracellular localization of 1849-ICG via fluorescence microscopy. NIR-PIT-induced cell death was observed by performing cell viability imaging assay. In contrast to the other test groups, tumor growth was significantly inhibited by NIR-PIT with a statistically significant difference in relative tumor volumes for 27 d after the treatment start date [2.83 ± 0.38(NIR-PIT) vs 5.42 ± 1.61(Untreated), vs 4.90 ± 0.87(NIR), vs 4.28 ±1.87(1849-ICG), vs 4.35 ± 1.42(anti-TF 1849), at Day 27, P < 0.05]. Tumors that received NIR-PIT showed evidence of necrotic cell death-associated features upon hematoxylin-eosin staining accompanied by a decrease in Ki-67-positive cells(a cell proliferation marker) by IHC examination.CONCLUSION The TF-targeted NIR-PIT with the 1849-ICG conjugate can potentially open a new platform for treatment of TF-expressing pancreatic cancer.Winn Aung Atsushi B Tsuji Aya Sugyo Hiroki Takashima Masahiro Yasunaga Yasuhiro Matsumura Tatsuya Higashi 2018World Journal of Gastroenterology2018,24,48:7
5Paleoenvironmental information recorded by pollen in B-3GC gravity core in Okinawa Trough显示文摘Based on pollen records in B-3GC gravity core, environmental change since 9500 aBP of Okinawa Trough and its adjacent islands was derived. The result showed that the most time during this period was in a warm temperate climate except in middle Holocene (6800-4400 aBP) that was under subtropical climate control. During 9500-8300 aBP and 3100-2000 aBP periods, it appeared colder and drier than the rest time. The original area of pollen sources surrounding Okinawa Trough was covered by evergreen and deciduous broadleaf forest alternatively with mixed broad-leaf-conifer forest distributed in high mountainous areas. Usually, these three kinds of forests existed at the same time with difference in altitude. Pollen from subtropical and tropical plants increased obviously in about 5000-6000 aBP, reflecting a great lifting of vegetation zone and expansion of evergreen broad-leaf forest in the study area. However, there was a slight descending of plant zone and shrinking of evergreen broadleaf forest duringSONG Changqing, SUN Xiangjun & Yoshiki SaitoNational Natural Science Foundation of China, Beijing 100085, China Open Lab of Marine Geology, Tongji University, Shanghai 200039, China Institute of Botany, Chinese Academy of Sciences, Beijing 100093, China Geological Survey of Japan, Higashi 1-1-3, Tsukuba, Ibaraki, 305-8567,Japan 2001Chinese Science Bulletin2001,46,11:7
6Colon perforation due to antigenemia-negative cytomegalovirus gastroenteritis after liver transplantation: A case report and review of literature显示文摘BACKGROUND Cytomegalovirus(CMV) remains a critical complication after solid-organ transplantation. The CMV antigenemia(AG) test is useful for monitoring CMV infection. Although the AG-positivity rate in CMV gastroenteritis is known to be low at onset, almost all cases become positive during the disease course. We treated a patient with transverse colon perforation due to AG-negative CMV gastroenteritis, following a living donor liver transplantation(LDLT).CASE SUMMARY The patient was a 52-year-old woman with decompensated liver cirrhosis as a result of autoimmune hepatitis who underwent a blood-type compatible LDLT with her second son as the donor. On day 20 after surgery, upper and lower gastrointestinal endoscopy(GE) revealed multiple gastric ulcers and transverse colon ulcers. The biopsy tissue immunostaining confirmed a diagnosis of CMV gastroenteritis. On day 28 after surgery, an abdominal computed tomography revealed transverse colon perforation, and simple lavage and drainage were performed along with an urgent ileostomy. Although the repeated remission and aggravation of CMV gastroenteritis and acute cellular rejection made the control of immunosuppression difficult, the upper GE eventually revealed an improvement in the gastric ulcers, and the biopsy samples were negative for CMV. The CMV-AG test remained negative, therefore, we had to evaluate the status of the CMV infection on the basis of the clinical symptoms and GE.CONCLUSION This case report suggests a monitoring method that could be useful for AGnegative CMV gastroenteritis after a solid-organ transplantation.Takahiro Yokose Hideaki Obara Masahiro Shinoda Yutaka Nakano Minoru Kitago Hiroshi Yagi Yuta Abe Yohei Yamada Kentaro Matsubara Go Oshima Shutaro Hori Sho Ibuki Hisanobu Higashi Yuki Masuda Masanori Hayashi Miho Kawaida Takehiko Mori Takumi Fujimura Ken Hoshino Kaori Kameyama Tatsuo Kuroda Yuko Kitagawa 2019World Journal of Gastroenterology2019,25,15:5

9GIS COMPONENT BASED 3D LANDSLIDE HAZARD ASSESSMENT SYSTEM: 3DSLOPEGIS显示文摘In this paper, based on a new Geographic Information System (GIS) grid-based three-dimensional (3D) deterministic model and taken the slope unit as the study object, the landslide hazard is mapped by the index of the 3D safety factor. Compared with the one-dimensional (1D) model of infinite slope, which is now widely used for deterministic model based landslide hazard assessment in GIS, the GIS grid-based 3D model is more acceptable and is more adaptable for three-dimensional landslide. Assuming the initial slip as the lower part of an ellipsoid, the 3D critical slip surface in the 3D slope stability analysis is obtained by means of a minimization of the 3D safety factor using the Monte Carlo random simulation. Using a hydraulic model tool for the watershed analysis in GIS, an automatic process has been developed for identifying the slope unit from digital elevation model (DEM) data. Compared with the grid-based landslide hazard mapping method, the slope unit possesses clear topographical meaning, so its results are more credible. All the calculations are implemented by a computational program, 3DSlopeGIS, in which a GIS component is used for fulfilling the GIS spatial analysis function, and all the data for the 3D slope safety factor calculation are in the form of GIS data (the vector and the grid layers). Because of all these merits of the GIS-based 3D landslide hazard mapping method, the complex algorithms and iteration procedures of the 3D problem can also be perfectly implemented.XIE Mo-wen, ZHOU Guo-yun, ESAKI Tetsuro(Institute of Environmental Systems, Kyushu University, Hakozaki 6-10-1, Higashi Ku, Fukuoka, 812-8581, Japan) 2003Chinese Geographical Science2003,13,1:4

11An unusual enteropathy-associated T-cell lymphoma with MYC translocation arising in a Japanese patient:A case report显示文摘Enteropathy-associated T-cell lymphoma(EATL) is a rare peripheral T-cell lymphoma classified into 2 types,with or without celiac disease,based on histology.Type 2 EATL is less commonly associated with celiac disease,in which cells are characterized by being monomorphic and small-to medium-sized.Cells are characterized by CD8 and CD56 expression and c-MYC oncogene locus gain.We present an atypical case of type 2 EATL in the jejunum,with human T-lymphotropic virus-1 that was CD4-CD8+ CD56-CD30-CD25-TIA-1+ and granzyme B+ on immunohistological staining.It also displayed translocation of chromosome 8p24(c-MYC),as determined by fluorescent in situ hybridization.Mucosal spreading and intraepithelial invasion by lymphoma with villous atrophy were detected adjacent to the mucosal layer.The lymphoma may be derived from intraepithelial CD8+ T cells,similar to celiac disease.Kenji Okumura Masahiko Ikebe Tatsuro Shimokama Morishige Takeshita Nao Kinjo Keishi Sugimachi Hidefumi Higashi 2012World Journal of Gastroenterology2012,18,19:3
12Ectopic hepatocellular carcinoma mimicking a retroperitoneal tumor:A case report显示文摘BACKGROUND An ectopic hepatocellular carcinoma(EHCC)arises from the ectopic liver which is defined as a hepatic organ or tissue not connected to surrounding tissues.EHCC is a rare disease and it is difficult to diagnose preoperatively.Furthermore,the clinical features are not fully elucidated.CASE SUMMARY A retroperitoneal tumor(6 cm)was located at the dorsal side of the pancreas head on abdominal ultrasonography in an 81-year old woman positive for hepatitis C virus antibody.Contrast enhanced-computed tomography and gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging showed viable HCC patterns with early enhancement and delayed washout.The tumor markers-serum alphafetoprotein and alpha-fetoprotein-L3%-were increased to 30.1 ng/m L and83.1%,respectively.Protein induced by vitamin K absence or antagonist-Ⅱwas within normal levels(17 m AU/m L).Positron emission tomography-computed tomography showed strong accumulation into the tumor(Standardized Uptake Value max:13.8),and the tumor cytology following endoscopic ultrasoundguided fine needle aspiration showed poorly differentiated carcinoma.Tumor extirpation was performed,and operative findings showed that the retroperitoneal tumor was disconnected from the pancreas and the liver.Swollen lymph nodes near the tumor were histologically normal.On histological examination,the tumor was finally diagnosed as EHCC with Arginase-1 positive expression.CONCLUSION We report our experience of a rare EHCC which was difficult to diagnose,and we present a review of the literature.Yuki Adachi Hiromitsu Hayashi Toshihiko Yusa Toru Takematsu Kazuki Matsumura Takaaki Higashi Kensuke Yamamura Takanobu Yamao Katsunori Imai Yo-ichi Yamashita Hideo Baba 2020World Journal of Gastroenterology2020,26,18:3

14Overproduction of reactive oxygen species–obligatory or not for induction of apoptosis by anticancer drugs显示文摘Many studies demonstrate that conventional anticancer drugs elevate intracellular level of reactive oxygen species(ROS) and alter redox-homeostasis of cancer cells. It is widely accepted that anticancer effect of these chemotherapeutics is due to induction of oxidative stress and ROS-mediated apoptosis in cancer. On the other hand, the harmful side effects of conventional anticancer chemotherapy are also due to increased production of ROS and disruption of redox-homeostasis of normal cells and tissues. This article describes the mechanisms for triggering and modulation of apoptosis through ROS-dependent and ROS-independent pathways. We try to answer the question: 'Is it possible to induce highly specific apoptosis only in cancer cells, without overproduction of ROS, as well as without harmful effects on normal cells and tissues?' The review also suggests a new therapeutic strategy for selective killing of cancer cells, without significant impact on viability of normal cells and tissues, by combining anticancer drugs with redox-modulators, affecting specific signaling pathways and avoiding oxidative stress.Donika Ivanova Zhivko Zhelev Ichio Aoki Rumiana Bakalova Tatsuya Higashi 2016Chinese Journal of Cancer Research2016,28,4:3
15Comparison of cerebral activation between motor execution and motor imagery of self-feeding activity显示文摘Motor imagery is defined as an act wherein an individual contemplates a mental action of motor execution without apparent action.Mental practice executed by repetitive motor imagery can improve motor performance without simultaneous sensory input or overt output.We aimed to investigate cerebral hemodynamics during motor imagery and motor execution of a self-feeding activity using chopsticks.This study included 21 healthy right-handed volunteers.The self-feeding activity task comprised either motor imagery or motor execution of eating sliced cucumber pickles with chopsticks to examine eight regions of interest:pre-supplementary motor area,supplementary motor area,bilateral prefrontal cortex,premotor area,and sensorimotor cortex.The mean oxyhemoglobin levels were detected using near-infrared spectroscopy to reflect cerebral activation.The mean oxyhemoglobin levels during motor execution were significantly higher in the left sensorimotor cortex than in the supplementary motor area and the left premotor area.Moreover,significantly higher oxyhemoglobin levels were detected in the supplementary motor area and the left premotor area during motor imagery,compared to motor execution.Supplementary motor area and premotor area had important roles in the motor imagery of self-feeding activity.Moreover,the activation levels of the supplementary motor area and the premotor area during motor execution and motor imagery are likely affected by intentional cognitive processes.Levels of cerebral activation differed in some areas during motor execution and motor imagery of a self-feeding activity.This study was approved by the Ethical Review Committee of Nagasaki University(approval No.18110801)on December 10,2018.Moemi Matsuo Naoki Iso Kengo Fujiwara Takefumi Moriuchi Daiki Matsuda Wataru Mitsunaga Akira Nakashima Toshio Higashi 2021Neural Regeneration Research2021,16,4:3

18Impaired coronary microvascular endothelial function in men with metabolic syndrome显示文摘AIM: To assess coronary endothelial function of conduit and resistance vessels in patients with metabolic syndrome (MS). METHODS: Seventy-eight men (mean age, 57 years) with chest pain and angiographically normal coronary arteries were included in the study. Patients with coronary spastic angina were excluded. Changes in coronary artery diameter and coronary blood flow (CBF) in response to acetylcholine (ACh) were determined using quantitative coronary angiography and Doppler velocity measurements. Coronary flow reserve was calculated as the ratio of coronary blood velocity after adenosine triphosphate infusion relative to baseline values. Patients were divided into two groups based on the presence or absence of MS. RESULTS: There were 24 patients in the MS group (31%). The increase in CBF in response to ACh infusion was impaired in the MS group (P < 0.0001) compared to the non-MS group, whereas changes in coronary artery diameter in response to ACh infusion did not differ between the two groups. Multivariate regression analysis revealed that MS was a significant factor associated with the lesser change in CBF induced by ACh infusion at 30 μg/min (P < 0.0001, r 2 = 0.46). CONCLUSION: Coronary endothelial dysfunction was present at the level of resistance vessels but not conduit vessels in the MS patients included in our study.Hiroki Teragawa Naoya Mitsuba Kenji Nishioka Kentaro Ueda Shingo Kono Yukihito Higashi Kazuaki Chayama Yasuki Kihara 2010World Journal of Cardiology2010,2,7:2
