Abstract
Although the lithic cutting-edge productivity has long been recognized as a quantifiable aspect of prehistoric human technological evolution, there remains uncertainty how the productivity changed during the Middle-to-Upper Paleolithic transition. Here we present the cutting-edge productivity of eight lithic assemblages in the eastern Mediterranean region that represent a chrono-cultural sequence including the Late Middle Paleolithic, Initial Upper Paleolithic, the Early Upper Paleolithic, and the Epipaleolithic. The results show that a major increase in the cutting-edge productivity does not coincide with the conventional Middle-Upper Paleolithic boundary characterized by the increase in blades in the Initial Upper Paleolithic, but it occurs later in association with the development of bladelet technology in the Early Upper Paleolithic. Given increasing discussions on the complexity of Middle-Upper Paleolithic cultural changes, it may be fruitful to have a long-term perspective and employ consistent criteria for diachronic comparisons to make objective assessment of how cultural changes proceeded across conventional chrono-cultural boundaries.

Abstract
We successfully performed electron scattering off unstable nuclei which were produced online from the photofission of uranium. The target ^{137}Cs ions were trapped with a new target-forming technique that makes a high-density stationary target from a small number of ions by confining them in an electron storage ring. After developments of target generation and transportation systems and the beam stacking method to increase the ion beam intensity up to approximately 2×10^{7} ions per pulse beam, an average luminosity of 0.9×10^{26} cm^{-2} s^{-1} was achieved for ^{137}Cs. The obtained angular distribution of elastically scattered electrons is consistent with a calculation. This success marks the realization of the anticipated femtoscope which clarifies the structures of exotic and short-lived unstable nuclei.

Abstract
Flerovium (Fl, element 114) is the heaviest element chemically studied so far. To date, its interaction with gold was investigated in two gas-solid chromatography experiments, which reported two different types of interaction, however, each based on the level of a few registered atoms only. Whereas noble-gas-like properties were suggested from the first experiment, the second one pointed at a volatile-metal-like character. Here, we present further experimental data on adsorption studies of Fl on silicon oxide and gold surfaces, accounting for the inhomogeneous nature of the surface, as it was used in the experiment and analyzed as part of the reported studies. We confirm that Fl is highly volatile and the least reactive member of group 14. Our experimental observations suggest that Fl exhibits lower reactivity towards Au than the volatile metal Hg, but higher reactivity than the noble gas Rn.

Abstract
Boron Neutron Capture Therapy (BNCT) is a radiotherapy for the treatment of intractable cancer. In BNCT precise determination of 10B concentration in whole blood sample before neutron irradiation of the patient, as well as accurate neutron dosimetry, is crucial for control of the neutron irradiation time. For this purpose ICP-AES and neutron induced prompt γ-ray analysis are generally used. In Ibaraki Neutron Medical Research Center (iNMRC), an intense proton beam will be accelerated up to 8 MeV, which can also be used for Charged Particle Activation Analysis (CPAA). Thus, in this study, we apply the CPAA utilizing the proton beam to non-destructive and accurate determination of 10B concentration in whole blood sample. A CPAA experiment is performed by utilizing an 8 MeV proton beam from the tandem accelerator of Nuclear Science Research Institute in Japan Atomic Energy Agency. The 478 keV γ-ray of 7Be produced by the 10B(p, α)7Be reaction is used to quantify the 10B in human blood. The 478 keV γ-ray intensity is normalized by the intensities of the 847 keV and 1238 keV γ-rays of 56Co originating from Fe in blood. The normalization methods were found to be linear in the range of 3.27 μg 10B/g to 322 μg 10B/g with correlation coefficients of better than 0.9999.

Abstract
We observed the atomic 1s and 2p states of π^{-} bound to ^{121}Sn nuclei as distinct peak structures in the missing mass spectra of the ^{122}Sn(d,^{3}He) nuclear reaction. A very intense deuteron beam and a spectrometer with a large angular acceptance let us achieve a potential of discovery, which includes the capability of determining the angle-dependent cross sections with high statistics. The 2p state in a Sn nucleus was observed for the first time. The binding energies and widths of the pionic states are determined and found to be consistent with previous experimental results of other Sn isotopes. The spectrum is measured at finite reaction angles for the first time. The formation cross sections at the reaction angles between 0° and 2° are determined. The observed reaction-angle dependence of each state is reproduced by theoretical calculations. However, the quantitative comparison with our high-precision data reveals a significant discrepancy between the measured and calculated formation cross sections of the pionic 1s state.

Abstract
Fission-fragment mass distributions were measured for ^{237-240}U, ^{239-242}Np, and ^{241-244}Pu populated in the excitation-energy range from 10 to 60 MeV by multinucleon transfer channels in the reaction ^{18}O+^{238}U at the Japan Atomic Energy Agency tandem facility. Among them, the data for ^{240}U and ^{240,241,242}Np were observed for the first time. It was found that the mass distributions for all the studied nuclides maintain a double-humped shape up to the highest measured energy in contrast to expectations of predominantly symmetric fission due to the washing out of nuclear shell effects. From a comparison with the dynamical calculation based on the fluctuation-dissipation model, this behavior of the mass distributions was unambiguously attributed to the effect of multichance fission.

Abstract
The first elastic electron scattering has been successfully performed at the self-confining radioactive-isotope ion target (SCRIT) facility, the world's first electron scattering facility for SCRIT technique achieved high luminosity (over 10^{27} cm^{-2} s^{-1}, sufficient for determining the nuclear shape) with only 10^{8} target ions. While ^{132}Xe used in this time as a target is a stable isotope, the charge density distribution was first extracted from the momentum transfer distributions of the scattered electrons by comparing the results with those calculated by a phase shift calculation.

Abstract
To understand the roles of pluripotent stem cell-inducing genes in gastric cancer, the expression of Krüppel-like factor 4 (KLF4), Nanog, octamer-binding transcription factor 4 (Oct4), avian myelocytomatosis viral oncogene homolog (c-Myc) and sex-determining region Y-box 2 (SOX2) was examined using the newly developed gastric carcinoma tissue microarray. The associations between the immunohistochemical expression levels of the pluripotency-inducing factors and the clinicopathological data of 108 patients with gastric cancer were analyzed. No associations were identified between the expression levels of the five pluripotency-inducing factors and the tumor-node-metastasis (TNM) classification or clinicopathological characteristics of the patients. In addition, multivariate analysis revealed no association of Nanog, Oct4, SOX2 or c-Myc with the prognosis of the gastric cancer patients; however, low expression of KLF4 was determined to be an independent negative prognostic factor (P=0.0331), particularly in patients who underwent R0 resection (TNM stages 2 and 3; P=0.0048). In summary, low KLF4 expression was found to be negatively associated with overall survival, and may therefore be a useful prognostic marker in gastric cancer patients.

Abstract
Epithelial cell adhesion molecule (EpCAM) is a marker for circulating tumor cells (CTCs) in various types of cancer, while cluster of differentiation 44 (CD44) is a marker for gastric cancer (GC) stem cells. To evaluate the clinical significance of CD44+ CTCs in patients with GC in the present study, the number of EpCAM+CD44+ and EpCAM+CD44- cells were detected in the peripheral blood of 26 GC patients and 12 healthy volunteers using flow cytometry. The number (mean ± standard deviation) of EpCAM+CD44+ cells in the GC patients and healthy volunteers was 69.9±52.0 and 0.91±2.10, respectively (P=0.0001), while that of EpCAM+CD44- cells was 59.1±88.0 and 9.83±9.91, respectively (P=0.0313). The sensitivity and specificity of EpCAM+CD44+ cell detection for the identification of GC patients were 92.3 and 100%, respectively. By contrast, the values of EpCAM+CD44- cell detection were 76.9 and 83.3%, respectively. The number of EpCAM+CD44+ cells in the GC patients was correlated with the disease stage (P=0.0423), the depth of the tumor (P=0.0314) and venous invasion (P=0.0184) in the resected tumor specimens, while the number of EpCAM+CD44- cells did not correlate with any clinicopathological factors. The number of EpCAM+CD44+ cells significantly decreased following surgical resection of the tumor or induction of systemic chemotherapy. Additionally, atypical cells with a high nuclear to cytoplasmic ratio were morphologically detected in the sorted EpCAM+CD44+ cells. These results suggested that CD44+ CTCs, but not CD44- CTCs, reflect the malignant status of the primary tumor in patients with GC, providing a candidate biomarker for diagnosis and treatment response.

Abstract
BACKGROUND Prognosis of breast cancer patients has been reported to depend on the expression of induced pluripotent stem (iPS) cell-inducing factors: KLF4 and NANOG. However, the relationship between KLF4 or NANOG expression in each breast cancer subtype and the life prognosis has not been elucidated. METHOD KLF4 and NANOG expression levels were evaluated in 208 patients using a newly developed tissue microarray (TMA). In vitro, siRNA against klf4 (siKLF4) was transfected in TNBC cell line MDA-MB-231, and the expression of KLF4 was inhibited. RESULTS Triple-negative breast cancer (TNBC) patients in KLF4 high-expression (upper) group had more favorable overall survival (OS) and disease-free survival (DFS) rates than KLF4 lower group (p = 0.0453 and p = 0.0427). In contrast, patients in the NANOG upper group had significantly poorer prognosis than lower group in TNBC breast cancer subtypes (p < 0.0001). Multivariate analysis showed that KLF4 (p = 0.0313), NANOG (p = 0.0002), and TNM stage (p = 0.0001) are mutually independent prognostic factors. It was also shown that the proliferation and invasion ability of siKLF4-induced TNBC cells were up-regulated significantly. CONCLUSION Our findings suggested that KLF4 and NANOG expression levels were favorable prognostic factors for TNBC patients. KLF4 also had an ability to inhibit the proliferation and invasion of TNBC.

Abstract
No traditional Japanese and Chinese herbal preparations have been shown to be effective antitumor agents, and a Japanese herbal therapy (Kampo medicine) for cancer that causes fewer adverse drug reactions than orthodox pharmaceuticals is desired. Our present study demonstrated that a Kampo preparation Daikenchuto (DKT) exerts an antitumor effect against various cancer cells. We also discovered an antitumor factor in Japanese Zanthoxylum peel, which is an ingredient of DKT. Breast, esophageal, gastric, and colon cancer cell lines were individually incubated with DKT for 1-72 h, followed by assessment of tumor growth inhibition by MTT assay. The cancer cells were also analyzed for apoptotic changes after DKT treatment. Nude mice were used to establish a model of gastric cancer tumor growth and peritoneal disseminated metastasis, in which the number of peritoneal disseminations was evaluated after oral administration of DKT for 4 weeks. In addition, the antitumor effects of the individual DKT ingredients (viz., ginseng, Japanese Zanthoxylum peel, and processed ginger) and other Kampo preparations were also analyzed. The antitumor effect of DKT was demonstrated in gastric, breast, esophageal, and colon cancer cells. DKT treatment induced apoptosis in these cells. Oral administration of DKT had a tendency to reduce the growth and significantly reduced the peritoneal dissemination of gastric cancer in the nude mouse model compared with control. DKT exhibited a higher antitumor effect than other Kampo preparations. Furthermore, Japanese Zanthoxylum peel, an ingredient of DKT, showed a particularly potent antitumor effect. Our study indicated that DKT is useful as a Kampo preparation for cancer therapy. We also showed that Japanese Zanthoxylum peel, an ingredient of DKT, contains an antitumor factor.

Abstract
Mitotically quiescent cancer stem cells (CSC) are hypothesized to exhibit a more aggressive phenotype involving greater therapeutic resistance and metastasis. The aim of our study was to develop a method for identifying quiescent CSC in esophageal squamous cell carcinoma (ESCC) based on their expression of the p75 neurotrophin receptor (p75NTR) and other proposed CSC markers, such as CD44 and CD90. Double immunostaining of surgical ESCC specimens revealed that the mean Ki-67-labeling index of the p75NTR-positive cells was significantly lower than that of the p75NTR-negative cells. Real-time PCR analysis of sorted fractions of ESCC cell lines (KYSE cells) revealed that stem cell-related genes (Nanog, p63 and Bmi-1) and epithelial-mesenchymal transition (EMT)-related genes (N-cadherin and fibronectin) were expressed at significantly higher levels in the p75NTR-positive fractions than in the CD44-positive or CD90-positive fractions. In addition, the p75NTR-positive fractions exhibited significantly higher colony formation in vitro, significantly enhanced tumor formation in mice, and significantly greater chemoresistance against cisplatin (CDDP) than the CD44‑positive or CD90‑positive fractions. Furthermore, in both the cultured cells and those from the mouse xenograft tumors, the p75NTR‑positive/CD44-negative and p75NTR‑positive/CD90-negative KYSE cell fractions contained significantly higher proportions of mitotically quiescent cells. These results suggest that the mitotically quiescent CSC population in ESCC can be identified and isolated based on their p75NTR expression, providing researchers with a novel diagnostic and therapeutic target.

Abstract
BACKGROUND The fatty liver could increase the risk of serious acute ischemia reperfusion (I/R) injury, and hepatic steatosis is indeed a major risk factor for hepatic failure after grafting a fatty liver. MATERIALS & METHODS Fatty liver models of methionine- and choline-deficient high-fat mice were subjected to I/R injury with or without 5-aminolevulinic acid (5-ALA)/sodium ferrous citrate (SFC) treatment. Levels of hepatic enzymes, lipid peroxidation and apoptosis, inflammatory cytokines and heme oxygenase (HO)-1, and the carbon monoxide (CO) in the liver, and reactive oxygen species (ROS), inflammatory cytokines and members of the signaling pathway in isolated Kupffer were assessed. RESULTS Alanine aminotransferase and aspartate aminotransferase levels, the number of necrotic areas, thiobarbituric acid reactive substance content, TUNEL-positive cells, infiltrated macrophages, and the inflammatory cytokine expression after I/R injury were dramatically decreased, whereas the endogenous CO concentrations and the HO-1 expression were significantly increased by 5-ALA/SFC treatment. The expression of toll-like receptors 2 and 4, NF-κB and inflammatory cytokines and ROS production in Kupffer cells were significantly decreased with 5-ALA/SFC treatment. CONCLUSION 5-ALA/SFC significantly attenuates the injury level in the fatty liver after I/R injury.

Abstract
The present study evaluated the capture efficiency of esophageal and breast cancer cells with a modified 'polymeric circulating tumor cells (CTC)-chip' microfluidic device, which was developed for the isolation of circulating tumor cells. Esophageal cancer cell lines KYSE150, KYSE220 and KYSE510, and breast cancer cell lines MCF7, SKBR3 and MDA-MB-231 were used for evaluation. The capture efficiencies of the esophageal cancer cell lines in phosphate-buffered saline (PBS) were ~0.9, irrespective of epithelial cell adhesion molecule (EpCAM) expression, which was represented as the mean fluorescent intensity from 528 to 76. In the breast cancer cell lines, efficient capture was observed for MCF7 and SKBR3 in PBS; however, a low value of ~0.1 was obtained for MDA-MB-231. Fluorescent imaging of immunolabeled cells revealed marginal EpCAM expression in MDA-MB-231. Using whole blood, no clogging occurred in the microstructure-modified CTC-chip and efficiency of capture was successfully evaluated. Capture efficiencies for KYSE220 and MCF7 in whole blood were >0.7, but were of either equal or lesser efficiency in comparison to PBS. Therefore, the modified CTC-chip appears useful for clinical application due to its cost, practicality of use, and efficient cancer cell capture.

Abstract
INTRODUCTION Perforation of intramural metastasis to the stomach (IMS) from esophageal cancer during chemotherapy has not been reported. PRESENTATION OF CASE A 68-year-old male consulted our hospital due to appetite loss. He was diagnosed with advanced esophageal squamous cell carcinoma in the lower thoracic esophagus along with a large IMS in the upper stomach. The patient received preoperative chemotherapy of docetaxel, cisplatin, and 5-fluorouracil (DCF). During the second cycle of DCF, he had upper abdominal pain and was diagnosed with gastric perforation. Omental implantation repair for the perforation, peritoneal drainage, tube-gastrostomy, and tube-jejunostomy were performed. At 24 days after emergency surgery, he underwent thoracoscopic radical esophagectomy with total gastrectomy and reconstruction with colonic interposition. Pathological findings in the esophagus demonstrated complete replacement of the tumor by fibrosis. The gastric tumor was replaced by scar tissue with multinucleated giant cells along with a small amount of viable cancer cells. The patient was alive and healthy at 14 months after the radical operation, without tumor recurrence. DISCUSSION The gastric perforation occurred due to rapid regression of the IMS which had involved the whole gastric wall before chemotherapy. Close monitoring to detect rapid tumor shrinkage during chemotherapy in patients with IMS may be warranted. A two-step operation was proposed to achieve safe curative treatment in patients with perforation of IMS during preoperative chemotherapy. CONCLUSION We describe the first reported case of a patient with esophageal squamous cell carcinoma who showed perforation of IMS during preoperative chemotherapy.

Abstract
The low affinity neurotrophin receptor p75NTR is known to be expressed in the mitotically quiescent basal layer (BL) of the normal esophageal epithelium. The aim of the present study was to detect oncogenic changes in the p75NTR-positive BL during esophageal squamous carcinogenesis. The normal epithelium (NE), low-grade intraepithelial neoplasia (LGN), high-grade intraepithelial neoplasia (HGN), and esophageal squamous carcinoma (SCC), in which invasion was limited to the muscularis mucosa, were obtained from surgically removed esophagi. The expression of p75NTR, the proliferation marker ki67, hTERT, p53, and p63 was examined immunohistochemically. The expression of p75NTR was detected in these tissues with average staining indexes (number of stained cells/100 nucleated cells; SI) of 1.00, 0.99, 0.81, and 0.73, respectively. The expression of ki67 in the BL significantly increased with the progression from LGN to HGN. The expression of hTERT and p53 significantly increased with the progression from NE to LGN, and then increased in a stepwise manner in HGN and SCC, with SI (hTERT/p53) of 0.10/0.11, 0.32/0.45, 0.50/0.72, and 0.65/0.61, respectively. The expression of p63 showed no significant difference among NE, LGN, HGN, and SCC, with SI of 0.82, 0.77, 0.85, and 0.87, respectively. A correlation was observed between the expression of ki67 and p53 (P = 0.005), while a negative correlation was found between p75NTR and hTERT (P = 0.01). Our results demonstrated that phenotypic changes from quiescent to active proliferation in the p75NTR-positive BL occurred during the progression from LGN to HGN. The altered expression of hTERT and p53 in the BL was detected in LGN, which suggested that additional oncogenic events that disrupt mitotic regulation in the p75NTR-positive quiescent BL may play a crucial role in malignant transformation. Further investigations using the isolation and tracing of p75NTR-positive cells in precancerous epithelia may provide us with a better understanding of squamous carcinogenesis.

Abstract
We developed a new circulating tumor cell (CTC) chip in order to identify CTCs in the peripheral blood of cancer patients. In this study, we aimed to identify CTCs in the blood of breast cancer patients by using this CTC detecting system. In addition, we used this system to evaluate the response to anticancer agents. We were able to identify CTCs in 5 of 6 patients. In addition, the system showed that the number of CTCs had decreased after chemotherapy. Thus, the CTC detecting system was useful in the identification of CTCs in the breast cancer patients and in the early prediction of response to anticancer agents.

Abstract
Abstract
Background: Small cell carcinoma of the esophagus is rare and its prognosis is extremely poor. However, there is currently no in vitro model of this disease.
Methods: After obtaining written informed consent, we obtained a tumor from a 56-year-old female patient with esophageal small cell carcinoma in 2009 and transplanted it into a Severe Combined Immuno Deficiency (SCID) mouse. After successful transplantation, a tumor from the back of this mouse was minced with a sharp scissors without enzymes and was cultured in Ham F12/DMDM supplemented with 5% fetal bovine serum.
Results: Culture cells grew as adherent cells during the initial culture phase and gradually grew as floating aggregated cells. We carefully maintained these floating cells and transferred them without enzymes. These cells could passage to another flask with a split ratio of 1/10. We named these cells “TYUC-1”, and passaged them more than 85 times. The population doubling-time of TYUC-1 was approximately 30 hours. The G-band karyotype confirmed that these cells had a human origin. These cells could be transplanted to SCID mice with the same histological features of primary esophageal small cell carcinoma, and were shown to express TrkA, NGF, NSE, FGFRL1, p53, CD56, ALDH1A1, and CD44, but not CD133. A cDNA array also revealed that 9 genes were overexpressed while the expression of 33 genes was significantly lower than that in 28 esophageal squamous cell carcinoma (ESCC) cell lines. Whole exome sequencing revealed that TYUC-1 had TP53, PIK3CA, KMT2D, CACNA1H, NCOR1 and HRAS mutations. Furthermore, TYUC-1 had mutations in 128 genes, whereas 28 ESCC cell lines had no mutations in these genes.
Conclusions: We newly established TYUC-1 cells that exhibited neuroendocrine characteristics and expressed several stem cell-related molecules. These cells may be useful for understanding the characteristics of esophageal small cell carcinoma.

Abstract
Paroxysmal nocturnal hemoglobinuria (PNH) is acquired hemolytic anemia characterized by symptoms such as anemia and hemoglobinuria. In recent years, eculizumab as an anti-complement (C5) monoclonal antibody has been used for PNH and shown to have marked effects. We performed laparoscopic cholecystectomy in a patient with PNH being treated with eculizumab, and could avoid the risk of perioperative hemolysis and thrombosis. [Patient] The patient was a 48-year-old female who had developed PNH when she was 39 years old. At the age of 46 years, eculizumab administration was initiated once every 2 weeks. During the administration period, neither the progression of anemia nor hemoglobinuria was observed. In March 2013, gallstones were detected, and she was referred to our hospital for surgery. Eculizumab was administered 10 days before surgery, and laparoscopic cholecystectomy was performed in May 2013. After the operation, for the prevention of thrombosis, elastic stockings and a foot pump were used without anticoagulant administration. After the operation, neither the progression of anemia nor hemoglobinuria was observed. On postoperative day 5, eculizumab was administered as planned, and she showed a favorable general condition and was discharged. [Discussion] Perioperative care in PNH patients was conventionally considered to involve a high risk of developing anemia, thrombosis, or infection. However, after the advent of eculizumab, the control of the symptoms of PNH became possible in many patients. In this patient with PNH being treated with eculizumab, safe perioperative management was possible without the development of complications.

Abstract
BACKGROUND Pancreatic carcinoma (PC) is among the most lethal types of carcinomas worldwide. We aimed to establish well-defined PC cell lines in order to determine their resistance to chemotherapy. MATERIALS AND METHODS Cells cultured from the tumors of two patients were analyzed for xenograft formation, V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS) and TP53 mutations, chemosensitivity, and mRNAs encoding rate-limiting enzymes that metabolize anticancer drugs. RESULTS The TYPK-1 and TYPK-2 cell lines were established from the lymph node of a locally advanced PC and from the ascites of a multi-metastatic and multi-chemoresistant PC, respectively. Each cell line generated tumors in nude mice. KRAS and TP53 mutations were detected in TYPK-1 but not TYPK-2 cells. TYPK-1 cells were resistant to gemcitabine, and TYPK-2 cells were resistant to oxaliplatin. The gemcitabine sensitivity of each cell line correlated with the expression of mRNAs encoding DCK and SLCAC29A1. CONCLUSION TYPK-1 and TYPK-2 cells may contribute to investigations of resistance to anticancer drugs.

Abstract
PURPOSE Several video-assisted and robotic surgery techniques have been reported for resection of the thyroid and parathyroid glands. Our institute has started performing endoscopic thyroidectomy using the Lap-protector and E·Z-access system, referred to as E·Z-access using video-assisted neck surgery (EZ-VANS). In this report, we evaluate the safety and efficacy of this technique. METHODS From January 2007 to September 2014, 110 patients underwent resection of a primary thyroid tumor, 73 who underwent a cervical collar incision (the Open group) and 37 underwent EZ-VANS (the EZ-VANS group). RESULTS The average operating time was 159 and 172 min in the Open group and EZ-VANS group, respectively; the amount of blood loss was 46.5 and 54.7 ml, respectively; and the length of hospital stay after surgery was 4.3 and 5.2 days, respectively, with no significant differences observed between the two groups. The learning curve for the EZ-VANS technique was shorter than for open surgery. CONCLUSIONS We confirmed that the EZ-VANS technique is a safe and useful method for resection of benign and early malignant thyroid tumors.

Abstract
Esophagectomy in the prone position has recently been introduced as a less-invasive procedure for treating esophageal cancer. We herein present a case of esophageal squamous cell carcinoma (ESCC) treated with a bilateral thoracic approach in the prone position. The patient was a 69-year-old male diagnosed with middle thoracic ESCC. Computed tomography scans and fluorine-18-fluorodeoxyglucose revealed possible metastasis to the lymph nodes on the left dorsal side of the descending thoracic aorta (DTA). After preoperative chemotherapy, we dissected the lymph node metastasis on the left dorsal DTA using the left thoracic approach, following resection of the ESCC by a right thoracic approach in the same prone position. The postoperative course was uneventful, and the patient was discharged 23 days after surgery. A bilateral thoracic approach for esophageal cancer in the prone position may be a new option for surgically treating esophageal cancer.

Abstract
BACKGROUND/AIM Small cell carcinoma of the esophagus (SCCE) is a rare but very aggressive disease with poor prognosis. The aim of the present study was to identify a molecular signature to predict postoperative outcomes in patients with SCCE. MATERIALS AND METHODS Expression of microRNA was detected in surgically-removed SCCE tumors using microarrays. A SCCE cell line (TYUC-1) was established to investigate the biological role of differentially expressed microRNAs. RESULTS Hierarchical clustering of microRNA expression revealed two discrete clusters that were identical to the cases with rapid tumor relapse (n=3; median survival, 5.1 months) and the cases with long-term survival (n=3; median observation, 144.7 months), respectively. Eight microRNAs (miR-4323, miR-625, miR-3619-3p, miR-4419b, miR-1249, miR-4648, miR-4664-3p and miR-1203) showed significant correlation with tumor relapse (p<0.01). Migration of TYUC-1 was significantly inhibited by down-regulation of miR-625. CONCLUSION The expression profiles of microRNAs in tumors may represent a novel predictor for postoperative outcomes in patients with SCCE.

Abstract
Background Inhibition of metastasis through upregulation of immune surveillance is a major purpose of chemokine gene therapy. In this study, we focused on a membrane-bound chemokine CXCL16, which has shown a correlation with a good prognosis for colorectal cancer (CRC) patients. Methods We generated a CXCL16-expressing metastatic CRC cell line and identified changes in TNF and apoptosis-related factors. To investigate the effect of CXCL16 on colorectal liver metastasis, we injected SL4-Cont and SL4-CXCL16 cells into intraportal vein in C57BL/6 mice and evaluated the metastasis. Moreover, we analyzed metastatic liver tissues using flow cytometry whether CXCL16 expression regulates the infiltration of M1 macrophages. Results CXCL16 expression enhanced TNF-α-induced apoptosis through activation of PARP and the caspase-3-mediated apoptotic pathway and through inactivation of the NF-κB-mediated survival pathway. Several genes were changed by CXCL16 expression, but we focused on IRF8, which is a regulator of apoptosis and the metastatic phenotype. We confirmed CXCL16 expression in SL4-CXCL16 cells and the correlation between CXCL16 and IRF8. Silencing of IRF8 significantly decreased TNF-α-induced apoptosis. Liver metastasis of SL4-CXCL16 cells was also inhibited by TNF-α-induced apoptosis through the induction of M1 macrophages, which released TNF-α. Our findings suggest that the accumulation of M1 macrophages and the enhancement of apoptosis by CXCL16 might be an effective dual approach against CRC liver metastasis. Conclusions Collectively, this study revealed that CXCL16 regulates immune surveillance and cell signaling. Therefore, we provide the first evidence of CXCL16 serving as an intracellular signaling molecule.

Abstract
A 6 1-year-old man who was admitted to our hospital because of obstructive jaundice. He was diagnosed with locally advanced cancer of the pancreatic head on computed tomography. Gemcitabine (1,000 mg/m² on days 8 and 15, every 21 days) + S-1 (6 0 mg/m² on day 1-15, every 21 days) chemotherapy was administered because the tumor had invaded the common hepatic artery and portal vein. The tumor was reduced following 9 months of chemotherapy. Thus, subtotal stomach- preserving pancreaticoduodenectomy (SSPPD)was performed. The histopathological findings indicated no invasion of the cancer into the surrounding tissues. No recurrence has occurred 7 months after surgery. Neoadjuvant chemotherapy is important for effective treatment of locally advanced pancreatic cancer.

Abstract
Abstract
Introduction:
MicroRNA-210 regulates cancer cell proliferation by targeting fibroblast growth factor receptor-like 1 (FGFRL1) in esophageal squamous cell cancer (ESCC) (JBC 2011). The expression of FGFRL1 has been associated with tumor growth and lymph node metastasis. In the present study, we analyzed and compared the expression of FGFR1, FGFR2, FGFR3, and FGFR4 with that of FGFRL1 using a tissue microarray. We also examined whether antibodies for FGFRL1 inhibited the growth and motility of ESCC cells.
Material and Methods:
A squamous cell carcinoma tissue microarray established in Toyama University was used to evaluate the expression of the 5 FGFRs. Sixty-nine specimens of ESCC were obtained from 62 male and 7 female patients, with an average age of 64.4 years old, that underwent surgery between 1990 and 2008. The TNM stages of these patients were as follows; stage 1: 7, stage 2a; 10, stage 2b; 10, stage 3; 35, stage 4; 7. The immunohistochemical results of these patients were scored according to intensity and distribution after a careful examination by two independent researchers. The ESCC cell line KYSE520 was used for experimental analyses. Polyclonal and monoclonal antibodies for FGFRL1 were used to evaluate the function of FGFRL1.
Results:
The percentage of patients who tested positive for the expression of the different FGFRs was as follows: FGFRL-1, 81% (56/69); FGFR1, 65% (37/57); FGFR2, 36% (22/61); FGFR3, 21% (12/57); FGFR4, 39% (22/56). The prognosis of FGFRL1 positive patients was significantly worse than that of FGFRL1 negative patients. (P=0.0311). Both polyclonal and monoclonal antibodies inhibited the growth (50% reduction) and motility (25% reduction) of ESCC cells. However, no association was observed between the expression of the other FGFRs and patient prognosis. Regarding combination analysis of the expression of each FGFR, patients that co-expressed FGFRL1 and FGFR1 had the worst prognosis, while patients who tested negative for the expression of both FGFRL1 and FGFR4 had the best prognosis.
Conclusions:
Among the 5 FGFRs, the expression of FGFRL1 was the main oncogenic driving factor in ESCC patients. The expression of FGFR1 and FGFR4 may be a sub-driving factor of ESCC.

Abstract
Experimental investigations of transactinoide elements provide benchmark results for chemical theory and probe the predictive power of trends in the periodic table. So far, in gas-phase chemical reactions, simple inorganic compounds with the transactinoide in its highest oxidation state have been synthesized. Single-atom production rates, short half-lives, and harsh experimental conditions limited the number of experimentally accessible compounds. We applied a gas-phase carbonylation technique previously tested on short-lived molybdenum (Mo) and tungsten (W) isotopes to the preparation of a carbonyl complex of seaborgium, the 106th element. The volatile seaborgium complex showed the same volatility and reactivity with a silicon dioxide surface as those of the hexacarbonyl complexes of the lighter homologs Mo and W. Comparison of the product's adsorption enthalpy with theoretical predictions and data for the lighter congeners supported a Sg(CO)6 formulation.

Abstract
Data related to radioactivity released from the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident on 15 March 2011 gathered by residents of Miharu, Fukushima Prefecture, and by Tohoku University are presented. These data sets consist of (1) the earliest radiation monitoring by a Geiger counter in the town, (2) ratios of radioactivity between (132)Te and (137)Cs for a wide area between Fukushima and Tokyo, (3) radiation measurement of soil samples collected from 18 school grounds, and (4) external radiation exposure of 1400 students using OSL badges. By combining and analysing these various data sets, a curve for the cumulative total external exposure as a function of time, with 16 : 00 h on 15 March 2011 being time zero, is obtained. The average cumulative external dosage is estimated to be 10 mSv (σ = 4.2 mSv) over 10 years. In addition, the initiative that the residents of Miharu took in response to the FDNPP accident, which became known as The Misho Project (MP), is documented; in particular, the time at which the municipality instructed the immediate ingestion of iodine tablets by those under the age of 40, 13 : 00 h on 15 March 2011, is assessed.

Abstract
We report the case of an adult male with progressing focal nodular hyperplasia (FNH). Although imaging studies suggested that the tumor was a classical FNH, the tumor biopsy showed glutamine synthetase expression and heat shock protein 70 in part of the tumor. As we could not definitely distinguish this case of FNH from early hepatocellular carcinoma (HCC), we performed laparoscopic partial hepatectomy. The surgical resected specimen showed that the tumor had a central scar with vascular and cholangiolar proliferation, which is compatible with FNH. Immunohistochemical analysis showed that the molecular expression pattern was compatible with FNH in the center of the tumor, whereas it partly resembled early HCC in the periphery of the tumor. FNH progression is occasionally found, and the molecular pattern of the progressing area in FNH might resemble that of early HCC due to morphologic and phenotypic changes induced by the regenerative mechanism and the alteration of blood flow. We should carefully observe progressing FNH.

Abstract
MicroRNA (miR)-203 has been shown to induce squamous differentiation of epidermal stem cells through the suppression of p63. The aim of this study was to assess the tumor suppressor effect of miR-203 in esophageal squamous cell carcinoma (ESCC) with focus on the regulation of the cell fate decisions and organization of tumor tissue architecture in vivo. Our investigation establishing stable clones from ESCC cell lines with induced miR-203 expression resulted in significant growth inhibition in a mouse xenograft model. Small foci were observed in xenograft tumors with stratified squamous differentiation in conjunction with restored baso-apical polarity. The expression of the basement membrane protein laminine was localized at the center of the foci and the basal cell marker p75NTR was expressed in the innermost layer. The expression of ki67 and p63 was co-localized at the center layers, while involucrin was expressed in the outer layers. Flow cytometry revealed that the p75NTR-positive cells expressing p63 and Bmi1 were well maintained, while the expression of p63 was suppressed in the p75NTR-negative cells. Our cDNA microarray analysis demonstrated the upregulation of genes involved in regulating tissue architecture, such as BMP-4 and ZO-1 in the mir-203 transfectant. Investigation using surgically removed ESCC specimens revealed that the expression of miR-203 significantly correlated with a favorable prognosis. These results demonstrated that miR-203 regulated both basal and supra-basal cell components to induce differentiation with restored epithelial tissue architecture, leading to significant tumor growth inhibition in vivo. Those results suggest the use of miR-203 as a novel therapeutic and diagnostic target in patients with ESCC.

Abstract
It has been reported that chloride–proton exchanger ClC-5 and vacuolar-type H+-ATPase are essential for endosomal acidification in the renal proximal cells. Here, we found that ClC-5 is expressed in the gastric parietal cells which secrete actively hydrochloric acid at the luminal region of the gland, and that it is partially localized in the intracellular tubulovesicles in which gastric H+,K+-ATPase is abundantly expressed. ClC-5 was co-immunoprecipitated with H+,K+-ATPase in the lysate of tubulovesicles. The ATP-dependent uptake of 36Cl− into the vesicles was abolished by 2-methyl-8-(phenylmethoxy)imidazo[1,2-a]pyridine-3-acetonitrile (SCH28080), an inhibitor of H+,K+-ATPase, suggesting functional expression of ClC-5. In the tetracycline-regulated expression system of ClC-5 in the HEK293 cells stably expressing gastric H+,K+-ATPase, ClC-5 was co-immunoprecipitated with H+,K+-ATPase, but not with endogenous Na+,K+-ATPase. The SCH28080-sensitive 36Cl− transporting activity was observed in the ClC-5-expressing cells, but not in the ClC-5-non-expressing cells. The mutant (E211A-ClC-5), which has no H+ transport activity, did not show the SCH28080-sensitive 36Cl− transport. On the other hand, both ClC-5 and its mutant (E211A) significantly increased the activity of H+,K+-ATPase. Our results suggest that ClC-5 and H+,K+-ATPase are functionally associated and that they may contribute to gastric acid secretion.

Abstract
The management of synchronous asymptomatic colonic metastases from primary esophageal squamous cell carcinoma (ESCC) has not yet been reported. A 64-year-old male patient was diagnosed with middle thoracic ESCC. The patient received chemoradiotherapy and incomplete response/stable disease was achieved. Preoperative colonoscopy revealed a 1.0-cm submucosal tumor at the splenic flexure of the colon, and biopsy results indicated possible metastasis from primary ESCC. The patient underwent subtotal esophagectomy and the colonic tumor was excised. A postoperative pathological diagnosis confirmed that the colonic tumor had metastasized from primary ESCC. Even though the patient was discharged 18 days after surgery without any complications, he died on the 72nd postoperative day due to multiple bone metastases and pleural dissemination. Our findings suggest that even with well-controlled and asymptomatic colonic metastasis from primary esophageal lesions, the prognosis of patients with primary ESCC is poor.

Abstract
S-1 has been recommended as adjuvant chemotherapy in patients after curative surgery for gastric cancer. However, some patients suffer recurrence even after S-1 adjuvant chemotherapy. The present study was conducted to find a predictive marker of the efficacy of S-1 adjuvant chemotherapy. We examined the microRNA (miRNA) expression of 35 patients who underwent S-1 adjuvant chemotherapy after curative surgery (R0) for pathological stage II or III gastric cancer. miRNAs were extracted from formalin-fixed, paraffin-embedded specimens for analysis and miRNA expression was examined using miRNA oligo chips. Fifteen patients relapsed and 20 did not over 5 years. Five miRNAs (miR-92b, 422a, 4732-5p, 4758-3p and 221) were highly expressed according to the tumor/normal (T/N) ratio in the patients who relapsed but not in those who did not relapse (P-value <0.05) by microarray analysis. If tumors showed high expression of 4 miRNAs (miR-92b, 422a, 4732-5p and 4758-3p) their positive predictive value of relapse was 93.8% and negative predictive value was 92.3%. In this case, their disease-free survival rate and overall survival rate were very poor. Our findings indicate that miR-92b, miR‑422a, miR-4732-5p and miR-4758-3p are closely associated with relapse following S-1 adjuvant chemotherapy in gastric cancer.

Abstract
Although Barrett's esophagus may occur without gastric acid, Barrett's adenocarcinoma after total gastrectomy is rare. Here, we present Barrett's adenocarcinoma in long-segment Barrett's esophagus after total gastrectomy. The patient was a 74-year-old male who underwent total gastrectomy 44 years ago. An endoscopic examination revealed long-segment Barrett's esophagus starting 17 cm from the incisors and continuing 20 cm to esophagojejunostomy, with irregular mucosa 27-31 cm from the incisors. Pathological diagnosis of a biopsied specimen was adenocarcinoma. We performed subtotal esophagectomy with lymph node dissection in the prone position and reconstructed the esophagus with ileocolic interposition. Postoperative pathological diagnosis from a Barrett's epithelial section was well differentiated adenocarcinoma. This case had the longest interval from total gastrectomy and smallest oral margin of Barrett's epithelium. Our case suggested that careful surveillance is needed for patients exhibiting recurrent bile reflux following total gastrectomy.

Abstract
Cytokines play important roles in all stages of steatohepatitis, including hepatocyte injury, the inflammatory response, and the altered function of sinusoidal cells. This study examined the involvement of a major inflammatory cytokine, interferon-γ (IFN-γ), in the progression of steatohepatitis. In a steatohepatitis model by feeding a methionine- and choline-deficient high-fat (MCDHF) diet to both wild-type and IFN-γ-deficient mice, the liver histology, expression of genes encoding inflammatory cytokines, and fibrosis-related markers were examined. To analyze the effects of IFN-γ on Kupffer cells in vitro, we examined the tumor necrosis factor-α (TNF-α) production by a mouse macrophage cell line. Forty two days of MCDHF diet resulted in weight loss, elevated aminotransferases, liver steatosis, and inflammation in wild-type mice. However, the IFN-γ-deficient mice exhibited less extensive changes. RT-PCR revealed that the expression of tumor necrosis factor-α (TNF-α), transforming growth factor-β, inducible nitric oxide synthase, interleukin-4 and osteopontin were increased in wild-type mice, although they were suppressed in IFN-γ-deficient mice. Seventy days of MCDHF diet induced much more liver fibrosis in wild-type mice than in IFN-γ-deficient mice. The expression levels of fibrosis-related genes, α-smooth muscle actin, type I collagen, tissue inhibitor of matrix metalloproteinase-1, and matrix metalloproteinase-2, were dramatically increased in wild-type mice, whereas they were significantly suppressed in IFN-γ-deficient mice. Moreover, in vitro experiments showed that, when RAW 264.7 macrophages were treated with IFN-γ, they produced TNF-α in a dose-dependent manner. The present study showed that IFN-γ deficiency might inhibit the inflammatory response of macrophages cells and subsequently suppress stellate cell activation and liver fibrosis. These findings highlight the critical role of IFN-γ in the progression of steatohepatitis.

Abstract
BACKGROUND/PURPOSE Aquaporins (AQPs) are important in controlling bile formation. However, the exact role in human gallbladder carcinogenesis has not yet been defined. METHODS AQP-5-expressing gallbladder carcinoma (GBC) cell lines (NOZ) were transfected with anti-AQP-5 small interfering RNA (siRNA). Growth, migration, invasion assay, and drug susceptibility tests were performed. Next, microRNA (miRNA) expression was analyzed by miRNA oligo chip (3D-Gene®). AQP-5 and AQP-5-related miRNA target gene expressions were also analyzed using tissue microarray (TMA) in 44 GBC samples. RESULTS Treatment with AQP-5 siRNA decreased cell proliferation, migration, and invasion. On the other hand, those cells increased IC50 of gemcitabine. By performing miRNA assays, miR-29b, -200a, and -21 were shown to be highly overexpressed in cells treated with AQP-5 siRNA NOZ. When focusing on miR-21, phosphatase and tensin homolog (PTEN) was found to be a target of miR-21. In the TMA, AQP-5/PTEN coexpression was significantly associated with the depth of invasion and MIB-1 index (p = 0.003, 0.010). Survival of patients with a high AQP-5/PTEN coexpression was longer than that of patients with a low coexpression (p = 0.003). CONCLUSIONS Our result suggested that miR-21 and PTEN may contribute to the role of AQP-5 in GBC. AQP-5 and PTEN cascades are favorable biomarkers of GBC.
