Abstract
56 Background: L1 cell adhesion molecule (L1) is a 200-220 kDa transmembrane glycoprotein of the immunoglobulin super family initially identified in neural cells. L1 was detected in ovarian cancer in a stage-dependent manner, was found exclusively in the invasion front of colorectal cancer, and has been considered a stem cell marker in glioma. The authors have shown that mRNA expression of L1 was a significant prognostic factor in gastric cancer (Kodera et al. Gastrointestinal Cancer Symposium 2009, abst 37). Its role in gastric cancer was further investigated. Methods: Expression of L1 was observed by immunostaining in 72 surgically resected pT4A-stage gastric cancer specimens. The association of L1 with peritoneal seeding and prognosis was elucidated. mRNA expression of L1-expressing gastric cancer cell line, KATO3, was suppressed using siRNA (KATO3 L1-). Microarray was used to indentify molecules that differ in expression between KATO3 L1- and the parental cell line. Results: L1 was scarcely stained in non-cancerous epithelial cells and intestinal metaplastic cells. L1 was detected mainly in the cell surface membrane of cancer cells in 15 of 72 specimens, more often in the intestinal type cancer. No correlation was found between L1 expression and detection of cancer cells in the peritoneal washes or development of peritoneal carcinomatosis. Nevertheless, the prognosis of L1-positive cancer was significantly inferior (p = 0.024). Prognosis was particularly poor among 6 cases where L1 was expressed in cancer cells at the invasive front (median survival time 149 days). Of 40,000 genes evaluated in the microarray, mRNA expression of 50 genes were amplified by > 4-fold whereas the expression of 20 genes were attenuated to less than 1/4. Of these, expression of DYRK1A that induces apoptosis in conjunction with p53 was markedly suppressed to less than 1/8. Suppression of DYRK1A in the KATO3 L1- in comparison with the parental cell line was confirmed by RT-PCR. Conclusions: L1 affects prognosis of gastric cancer, particularly when it is expressed in cancer cells at the invasion front. Its role in the biology of gastric cancer has began to be elucidated. No significant financial relationships to disclose.

Abstract
The aim of this study was to examine the pharmacokinetics of nicorandil, a hybrid of an adenosine triphosphate-sensitive potassium channel opener and a nitrate, and to estimate its clinical doses in dogs with mild mitral valve regurgitation (MR). Nicorandil (0.1, 0.3, and 1.0 mg/kg) was administered orally to normal dogs and those with experimentally-induced MR, and its plasma concentrations were analyzed using high-performance liquid chromatography. Plasma concentrations increased dose-dependently after the administration of nicorandil, and were not different between normal dogs and those with MR. Similar to the effective plasma values obtained in cardiac disease in humans, the findings of this pharmacokinetic study may indicate that a dose of 0.3-1.0 mg/kg has the same effectiveness in dogs with cardiac dysfunction.

Abstract
Differential cross sections and photon-beam asymmetries for the gamma(p)-->K{+}Lambda(1520) reaction have been measured with linearly polarized photon beams at energies from the threshold to 2.4 GeV at 0.6<cos(theta){c.m.}{K}<1. A new bump structure was found at W approximately 2.11 GeV in the cross sections. The bump is not well reproduced by theoretical calculations introducing a nucleon resonance with J<or=3/2. This result suggests that the bump might be produced by a nucleon resonance possibly with J>or=5/2 or by a new reaction process, for example, an interference effect with the phi photoproduction having a similar bump structure in the cross sections.

Abstract
Photoproduction of Lambda(1520) with liquid hydrogen and deuterium targets was examined at photon energies below 2.4 GeV in the SPring-8 LEPS experiment. For the first time, the differential cross sections were measured at low energies and with a deuterium target. A large asymmetry of the production cross sections from protons and neutrons was observed at backward K+/0 angles. This suggests the importance of the contact term, which coexists with t-channel K exchange under gauge invariance. This interpretation was compatible with the differential cross sections, decay asymmetry, and photon beam asymmetry measured in the production from protons at forward K+ angles.

Abstract
BACKGROUND Patients with gastric cancer who have positive cytologic results for cancer cells in peritoneal washings (CY1) have poor outcomes, even in the absence of other distant metastases. A standard treatment for such patients remains to be established. METHODS We conducted a phase II trial with the 2-year survival rate as the primary endpoint. Patients who had gastric cancer with CY1 status but no other residual disease received postoperative chemotherapy with S-1 (1M tegafur-0.4M gimestat-1M otastat potassium) at a daily dose of 80mg/m(2) for 4 weeks, followed by 2 weeks of rest. This cycle was continued until disease progression or intolerable adverse events. D2 dissection was the recommended surgical procedure; splenectomy could be omitted at the discretion of the surgeon. Accrual of 50 patients was planned, and a 2-year survival rate of more than 36% was needed to exceed the historical control. RESULTS Forty-eight patients were enrolled, among whom 47 were assessable for survival and 46 for adverse reactions. Median overall survival was 705 days, and progression-free survival was 376 days. The 2-year survival rate was 47%. Median time to treatment failure was 288 days. Neutropenia was the commonest > or = grade 3 toxicity (6 patients), and anorexia was the most frequent > or = grade 2 non-hematologic toxicity (10 patients). CONCLUSIONS Gastrectomy followed by S-1 monotherapy resulted in survival that surpassed historical data and can serve as an active control treatment for future trials in patients who have gastric cancer with CY1 status in the Far East.

Abstract
Obstructive sleep apnea syndrome (OSAS) is related to the increased prevalence of cardiovascular disease and metabolic syndrome (MS). A novel adipokine, retinol binding protein-4 (RBP4), was reported to be associated with insulin resistance and the prevalence of type 2 diabetes. To examine whether plasma RBP4 is associated with insulin resistance and MS development in OSAS, we measured plasma RBP4 levels in 181 Japanese men (24 healthy controls and 40 mild, 64 moderate, and 53 severe OSAS) of whom 26 had mild glucose intolerance with HbA1c < or = 6.0%. After a full polysomnography, blood was collected between 06:00 and 07:00 AM. Plasma RBP4 levels in moderate/severe OSAS patients were higher than in control subjects. Plasma RBP4 was not correlated with apnea variables, HOMA-IR, or blood pressure. However, it was positively correlated with visceral fat areas and plasma triglyceride levels. The prevalence of MS was higher in severe OSAS patients than in mild/moderate OSAS and control subjects. Plasma RBP4 was higher in OSAS patients with MS than in those without MS. This study indicates that plasma RBP4 is associated with dyslipidemia, but not with insulin resistance, glucose intolerance, or hypertension in patients with OSAS. Visceral obesity may play key roles in increasing the plasma RBP4 level and MS development in OSAS.

Abstract
Although pH modification is one of the effective strategies for dissolving or preventing uroliths, little is known about its effects on the pharmacokinetics of phenobarbital in dogs. Five spayed, female Beagles were fed with a twice-daily diet that included potassium citrate and ammonium chloride for urine alkalinization and acidification, respectively. After a stabilizing period of 7 days, a single clinical dose of phenobarbital (3 mg/kg) was orally administered, and time-course changes in its serum and urine concentrations were determined by high-performance liquid chromatography. Total amounts of unchanged phenobarbital excreted into urine for 216 h were decreased by urine acidification and increased by urine alkalinization. The elimination half-life of serum phenobarbital in dogs with urine alkalinization was shortened and Cl(R) increased when compared with dogs with urine acidification. Other pharmacokinetic parameters, including C(max), T(max), AUC(0-216), Cl/F, and A(e0-216) were not changed by modification of the urine pH. These results suggest that the pH of urine is likely to be a determinant of the pharmacokinetics, especially urine excretion rate, of a clinical dose of oral phenobarbital. It is possible that the serum concentration of phenobarbital might be altered when a pH modifying-diet is administered for the purpose of dissolving or preventing uroliths.

Abstract
BACKGROUND On magnetic resonance imaging (MRI) using gadolinium diethylenetriamine pentaacetic acid (Gd-DTPA) as contrast medium, images of infarct regions are enhanced in acute myocardial infarction (AMI). In old myocardial infarction (OMI), thinning of the myocardial walls is present, but images are no longer enhanced by Gd-DTPA. On the other hand, MI in children with a history of Kawasaki disease (KD), several differences from adult MI are observed. HYPOTHESIS The aim of this study was to evaluate the lesions that result from OMI in children with a history of KD using MRI with Gd-DTPA as a contrast medium. METHODS The subjects were 16 young patients with a history of KD who were diagnosed as having OMI. Of these, both thinning of the myocardial wall and MRI enhancement by Gd-DTPA were observed in 4 cases, thinning alone was observed in 6 cases, Gd-DTPA image enhancement alone was observed in 3 cases, and neither thinning nor Gd-DTPA image enhancement was observed in 3 cases. RESULTS The Gd-DTPA-image-enhanced, OMI-induced lesions observed in patients with KD were different from those observed in adults; this might be attributable to histologic differences. CONCLUSION Magnetic resonance imaging using Gd-DTPA can evaluate myocardial thinning and presence of circulation noninvasively at the same time and is considered to be useful for long-term follow up of the patients with KD and OMI.

Abstract
The Sigma(1385) resonance, or Sigma;{*}, is well known as part of the standard baryon decuplet with spin J=3/2. Measurements of the reaction gammap-->K;{+}Sigma;{*0} are difficult to extract due to overlap with the nearby Lambda(1405) resonance. However, the reaction gamman-->K;{+}Sigma;{*-} has no overlap with the Lambda(1405) due to its charge. Here we report the first measurement of cross sections and beam asymmetries for photoproduction of the Sigma;{*-} from a deuteron target. The cross sections at forward angles range from 0.4 to 1.2 mub, with a broad maximum near E_{gamma} approximately 1.8 GeV. The beam asymmetries are negative, in contrast with positive values for the gamman-->K;{+}Sigma;{-} reaction.

Abstract
In the current review article, evidences on radical surgery for gastric cancer reported in the literature are highlighted. The authors conclude that extended lymphadenectomy offers a statistically significant survival benefit. This benefit is only evident if the operative mortality is less than 2%, as obtained in centers of excellence with a high-volume experience of resection of gastric cancer. Lymphadenectomy should no longer be considered only as a tool for cancer-staging, but also as a beneficial therapeutic measure.

Abstract
We report a CR case of advanced rectal cancer successfully treated with 39 courses of mFOLFOX6. The patient was a 29-year-old female with Stage IV rectal cancer. At first she was given IFL together with radiotherapy. It took effect for three months, and the therapeutic effect was PR, but interstitial pneumonia developed. Therefore, we shifted to mFOLFOX6, and she was treated with 39 courses. Grade 1 appeared several times for peripheral neuropathy, but recovered immediately. If we could control peripheral neuropathy with FOLFOX, it was thought that long-term survival could / be expected.

Abstract
We report the first entanglement-based quantum key distribution (QKD) experiment over a 100-km optical fiber. We used superconducting single photon detectors based on NbN nanowires that provide high-speed single photon detection for the 1.5-mum telecom band, an efficient entangled photon pair source that consists of a fiber coupled periodically poled lithium niobate waveguide and ultra low loss filters, and planar lightwave circuit Mach-Zehnder interferometers (MZIs) with ultra stable operation. These characteristics enabled us to perform an entanglement-based QKD experiment over a 100-km optical fiber. In the experiment, which lasted approximately 8 hours, we successfully generated a 16 kbit sifted key with a quantum bit error rate of 6.9 % at a rate of 0.59 bits per second, from which we were able to distill a 3.9 kbit secure key.

Abstract
Seven cases of myelodysplastic syndrome with myelofibrosis, which is defined using the following criteria: (1) pancytopenia with less than 5% blasts in the peripheral blood; (2) minimal or no splenomegaly; (3) myelofibrosis with cellular marrow; (4) absence of diffuse proliferation of blasts in the bone marrow; and (5) presence of myelodysplastic features of bone marrow or peripheral blood cells, are presented. They were in the range of 52-82 years old and consisted of 3 males and 4 females. Six out of 7 cases developed into acute leukaemia after 5 to 8 months from the onset and died from between 2 weeks to 8 months from the evolution to leukaemia. The type of leukaemia was acute myeloblastic in 3 patients, and acute myelo-megakaryoblastic in 3 patients. Another patient died of severe hepatic injury after 5 months from the onset of the disease. These findings revealed that the complication of myelofibrosis in the patients with myelodysplastic syndrome was an indicative sign of rapid progression to overt leukaemia or otherwise poor prognosis for survival. In addition myelodysplastic syndrome is thought to be major primary disorder for acute myelofibrosis. Myelodysplastic syndrome with myelofibrosis is closely associated with the neoplastic proliferation of megakaryoblasts in a considerable number of patients.
