Abstract
PURPOSE To compare the feasibilities and efficacies of the total extraperitoneal (TEP) technique and laparotomy for incarcerated obturator hernia repair. METHODS All study subjects were diagnosed with incarcerated obturator hernia, preoperatively and TEP was performed as for TEP groin hernia repair. The incarcerated intestine was retracted into the peritoneal cavity with the hernia sac. The obturator foramen was then covered with a rectangular mesh (9 × 13 cm), which also covered the internal inguinal ring, Hesselbach's triangle, and the femoral ring. Non-ischemia of the incarcerated bowel was confirmed laparoscopically. In patients undergoing laparotomy, the obturator foramen was closed by continuous sutures, and no prosthesis was used. We recorded the length of hospital stay, operative time, amount of intraoperative bleeding, and postoperative complications. RESULTS Twenty-two patients underwent obturator hernia repair in our hospital between January 2000 and December 2012, of whom 10 were treated with laparotomy and the remaining 12 via TEP. Three patients undergoing TEP were converted to laparotomy. The operation time was significantly longer in the conversion group compared with either the laparotomy or the TEP groups. There was no difference between the laparotomy and TEP groups regarding intraoperative bleeding. Patients who underwent TEP without conversion had a significantly shorter hospital stay than those who underwent laparotomy or required conversion. CONCLUSIONS TEP provides a suitable approach for incarcerated obturator hernia repair, with favorable results regarding hospital stay. TEP is a feasible, minimally invasive technique for the repair of incarcerated obturator hernias.

Abstract
We report on the measurement of the first 2(+) and 4(+) states of (66)Cr and (70,72)Fe via in-beam γ-ray spectroscopy. The nuclei of interest were produced by (p,2p) reactions at incident energies of 260 MeV/nucleon. The experiment was performed at the Radioactive Isotope Beam Factory, RIKEN, using the DALI 2γ-ray detector array and the novel MINOS device, a thick liquid hydrogen target combined with a vertex tracker. A low-energy plateau of 2(1)(+) and 4(1)(+) energies as a function of the neutron number was observed for N≥38 and N≥40 for even-even Cr and Fe isotopes, respectively. State-of-the-art shell model calculations with a modified Lenzi-Nowacki-Poves-Sieja (LNPS) interaction in the pfg(9/2)d(5/2) valence space reproduce the observations. Interpretation within the shell model shows an extension of the island of inversion at N=40 for more neutron-rich isotopes towards N=50.

Abstract
While adjuvant chemotherapy is preferable for colon cancer, treatment duration is controversial. This phase III trial is investigated optimal duration of adjuvant chemotherapy for Stage IIB/III colon cancer. Eighteen-month treatment with UFT/LV did not improve DFS compared with 6-month UFT/LV treatment. This study suggests that 6 months treatment duration is enough for Stage IIB/III colon cancer. Background While adjuvant chemotherapy is preferable for high-risk colon cancer, treatment duration is controversial. Oral uracil and tegafur (UFT)/leucovorin (LV) is widely used as a standard adjuvant chemotherapy for colon cancer in Japan. We conducted a phase III trial to investigate the optimal duration of adjuvant chemotherapy for stage IIB/III colon cancer. Patients and methods Patients with curatively resected stage IIB/III colon cancer were eligible for enrollment in this trial. Patients were registered within 6 weeks after surgery and were randomly assigned to receive UFT/LV for 28 of 35 days for 6 months in the control group or for 5 consecutive days per week for 18 months in the study group. The primary end point was the disease-free survival (DFS), and the secondary end points were overall survival (OS) and safety. Result A total of 1071 patients were registered from 233 centers. A statistically significant difference in DFS was not observed between the study group and the control group; the 5-year DFS was 69% in the study group and 69% in the control group. The 5-year OS was 85% in the study group and 85% in the control group. Conclusion Eighteen-month treatment with UFT/LV did not improve DFS or OS compared with 6-month UFT/LV treatment in patients with stage IIB/III colon cancer. The important finding from this study is that not 18 months but 6 months of treatment is enough for postoperative UFT/LV for stage IIB/III colon cancer. Clinical trial number UMIN-CTR C000000245.

Abstract
AIM To evaluate the safety, tolerability and pharmacokinetic profile of bapineuzumab after a single intravenous injection in Japanese patients with mild to moderate Alzheimer's disease. METHODS Participants received either a placebo (n = 8), or bapineuzumab 0.15 (n = 6), 0.5 (n = 6), 1.0 (n = 6) or 2.0 (n = 6) mg/kg. Serum concentrations of bapineuzumab, antibapineuzumab antibody and total plasma β-amyloidx-40 were assayed. RESULTS Adverse events for bapineuzumab and placebo groups were 71% and 88%, respectively. Treatment-emergent adverse events (cataract, injection site hemorrhage, nasopharyngitis, pneumonia and muscle twitching) reported for ≥2 participants were mild or moderate in severity and unrelated to bapineuzumab dose. No deaths, serious adverse events or withdrawals were reported. Mean peak concentration for bapineuzumab increased with dose, from 3.3 ± 0.9 μg/mL with the 0.15 mg/kg dose to 61.0 ± 32.8 μg/mL with 2.0 mg/kg. Mean bapineuzumab exposure (area under the curve from time 0 to last measurable concentration; μg·h/mL) increased in a linear manner with increasing dose (mean 1260 for 0.15 mg/kg, 4264 for 0.5 mg/kg, 7818 for 1.0 mg/kg, 15 313 for 2.0 mg/kg). Mean half-life ranged from 15 to 28 days, and clearance was similar across dose groups (range 0.12-0.17 mL/h/kg). CONCLUSIONS Plasma β-amyloidx-40 levels increased with increasing doses of bapineuzumab. Bapineuzumab was safe and well tolerated at all doses in Japanese patients with mild to moderate Alzheimer's disease. Geriatr Gerontol Int 2016; 16: 644-650.

Abstract
The β-decay half-lives of 110 neutron-rich isotopes of the elements from _{37}Rb to _{50}Sn were measured at the Radioactive Isotope Beam Factory. The 40 new half-lives follow robust systematics and highlight the persistence of shell effects. The new data have direct implications for r-process calculations and reinforce the notion that the second (A≈130) and the rare-earth-element (A≈160) abundance peaks may result from the freeze-out of an (n,γ)⇄(γ,n) equilibrium. In such an equilibrium, the new half-lives are important factors determining the abundance of rare-earth elements, and allow for a more reliable discussion of the r process universality. It is anticipated that universality may not extend to the elements Sn, Sb, I, and Cs, making the detection of these elements in metal-poor stars of the utmost importance to determine the exact conditions of individual r-process events.

Abstract
EAGLE was a randomized, multicenter phase III study which evaluated the superiority of bevacizumab 10 mg/kg plus FOLFIRI compared with bevacizumab 5 mg/kg plus FOLFIRI in patients with mCRC previously treated with first-line bevacizumab plus an oxaliplatin-based regimen. The results suggest that the higher 10 mg/kg dose offers no clear clinical benefit compared with bevacizumab 5 mg/kg in this setting. Background A targeted agent combined with chemotherapy is the standard treatment in patients with metastatic colorectal cancer (mCRC). The present phase III study was conducted to compare two doses of bevacizumab combined with irinotecan, 5-fluorouracil/leucovorin (FOLFIRI) in the second-line setting after first-line therapy with bevacizumab plus oxaliplatin-based therapy. Patients and methods Patients were randomly assigned to receive FOLFIRI plus bevacizumab 5 or 10 mg/kg in 2-week cycles until disease progression. The primary end point was progression-free survival (PFS), and secondary end points included overall survival (OS), time to treatment failure (TTF), and safety. Results Three hundred and eighty-seven patients were randomized between September 2009 and January 2012 from 100 institutions in Japan. Baseline patient characteristics were well balanced between the two groups. Efficacy was evaluated in 369 patients (5 mg/kg, n = 181 and 10 mg/kg, n = 188). Safety was evaluated in 365 patients (5 mg/kg, n = 180 and 10 mg/kg, n = 185). The median PFS was 6.1 versus 6.4 months (hazard ratio, 0.95; 95% confidence interval [CI] 0.75–1.21; P = 0.676), and median TTF was 5.2 versus 5.2 months (hazard ratio, 1.01; 95% CI 0.81–1.25; P = 0.967), respectively, for the bevacizumab 5 and 10 mg/kg groups. Follow-up of OS is currently ongoing. Adverse events, including hypertension and hemorrhage, occurred at similar rates in both groups. Conclusion Bevacizumab 10 mg/kg plus FOLFIRI as the second-line treatment did not prolong PFS compared with bevacizumab 5 mg/kg plus FOLFIRI in patients with mCRC. If bevacizumab is continued after first-line therapy in mCRC, a dose of 5 mg/kg is appropriate for use as second-line treatment. Clinical trial identifier UMIN000002557.

Abstract
Background A strategy for accelerating liver regeneration after hepatectomy would offer great benefits in preventing postoperative liver failure and improving surgical outcomes. Transforming growth factor (TGF) β is a potent inhibitor of hepatocyte proliferation. Recently, thrombospondin (TSP) 1 has been identified as a negative regulator of liver regeneration by activation of local TGF-β signals. This study aimed to clarify whether the LSKL (leucine–serine–lysine–leucine) peptide, which inhibits TSP-1-mediated TGF-β activation, promotes liver regeneration after hepatectomy in mice. Methods Mice were operated on with a 70 per cent hepatectomy or sham procedure. Operated mice received either LSKL peptide or normal saline intraperitoneally at abdominal closure and 6 h after hepatectomy. Perioperative plasma TSP-1 levels were measured by enzyme-linked immunosorbent assay in patients undergoing hepatectomy. Results Administration of LSKL peptide attenuated Smad2 phosphorylation at 6 h. S-phase entry of hepatocytes was accelerated at 24 and 48 h by LSKL peptide, which resulted in faster recovery of the residual liver and bodyweight. Haematoxylin and eosin tissue staining and blood biochemical examinations revealed no significant adverse effects following the two LSKL peptide administrations. In the clinical setting, plasma TSP-1 levels were lowest on the first day after hepatectomy. However, plasma TSP-1 levels at this stage were significantly higher in patients with subsequent liver dysfunction compared with levels in those without liver dysfunction following hepatectomy. Conclusion Only two doses of LSKL peptide during the early period after hepatectomy can promote liver regeneration. The transient inhibition of TSP-1/TGF-β signal activation using LSKL peptide soon after hepatectomy may be a promising strategy to promote subsequent liver regeneration.

Abstract
Endocytoscopy (ECS) is a novel endoscopic technique that allows detailed diagnostic examination of the gastrointestinal tract at the cellular level. We previously reported that use of ECS at ×380 magnification (GIF-Y0002) allowed a pathologist to diagnose esophageal squamous cell carcinoma (ESCC) with high sensitivity (94.9%) but considerably low specificity (46.7%) because this low magnification did not reveal information about nuclear abnormality. In the present study, we used the same magnifying endoscope to observe various esophageal lesions, but employed digital 1.6-fold magnification to achieve an effective magnification of ×600, and evaluated whether this improved the diagnostic accuracy in distinguishing neoplastic from non-neoplastic lesions.We examined the morphology of surface cells using vital staining with toluidine blue and compared the histological features of 40 cases, including 19 case of ESCC and 21 non-neoplastic esophageal lesions (18 cases of esophagitis, 1 case of glycogenic acanthosis, 1 case of leiomyoma, and 1 case of normal squamous epithelium). One endoscopist classified the lesions using the type classification, and we consulted one pathologist for judgment of the ECS images as 'neoplastic', 'borderline', or 'non-neoplastic'. At ×600 magnification, the pathologist confirmed that nuclear abnormality became evident, in addition to the information about nuclear density provided by observation at ×380. The overall sensitivity and specificity with which the endoscopist was able to predict neoplastic lesions using the type classification was 100% (19/19) and 90.5% (19/21), respectively, in comparison with values of 94.7% (18/19 cases) and 76.2% (16/21), respectively, for the pathologist using a magnification of ×600. The pathologist diagnosed two non-neoplastic lesions and one case of ESCC showing an apparent increase of nuclear density with weak nuclear abnormality as 'borderline'. Among the 21 non-cancerous lesions, two cases of esophagitis that were misdiagnosed by the endoscopist were also misinterpreted as 'neoplastic' by the pathologist. We have shown, by consultation with a pathologist, that an ECS magnification of ×600 (on a 19-inch monitor) is adequate for recognition of nuclear abnormality. We consider that it is feasible to diagnose esophageal neoplasms on the basis of ECS images, and that biopsy histology can be omitted if a combination of increased nuclear density and nuclear abnormality is observed.

Abstract
BACKGROUND Brain-derived neurotrophic factor (BDNF) is a member of the neurotrophin family of growth factors. Previous studies have demonstrated lower serum BDNF levels in patients with major depressive disorder (MDD) and reported an association between BDNF levels and depression-related personality traits in healthy subjects. The aim of the present study was to explore for a possible association between peripheral BDNF levels and personality traits in patients with MDD. METHODS In this cross-sectional study, a total of 123 inpatients with MDD (Diagnostic and Statistical Manual for Mental Disorders, 4th edition) at the Juntendo University Koshigaya Hospital were recruited. Serum levels of BDNF were measured. Personality traits were assessed using the 125-item short version of the Temperament and Character Inventory (TCI). RESULTS Multiple regression analysis adjusted for age, sex, body mass index, dose of antidepressant, and depression severity showed that TCI Self-Directedness (SD) scores were negatively associated with serum BDNF levels (β = -0.23, p = 0.026). CONCLUSIONS MDD patients who have low SD did not show the reduction in serum BDNF levels that is normally associated with depressive state. Our findings suggest that depression-related biological changes may not occur in these individuals.

Abstract
The aim of the present study was to examine whether the specific personality traits, Harm-Avoidance (HA) and Self-Directedness (SD) as measured by the Temperament and Character Inventory (TCI), were predictive for subsequent depressive episodes in remitted patients with major depressive disorders (MDDs) over a 4-year follow-up. A total of 109 inpatients with MDD participated in this study. The subjects completed the TCI when they were assessed to be in remission. They were divided into high or low HA groups and high or low SD groups, as discriminated by the quartile value. A total of 69 patients were followed-up over a 4-year period or until recurrence. Both Kaplan-Meier analysis and Cox׳s proportional hazards regression analysis indicated that patients with a low SD score had a significantly shorter time to recurrence from remission than patients with a high SD score even when some prognostic predictors were controlled for. In contrast, HA was not found to be a predictor of recurrence for future depressive episodes. A part of MDD patients with low scores in Self-Directedness are likely to develop depression over a subsequent period of time. Interventions that improve SD may help to delay recurrence of depression in MDD patients.

Abstract
BACKGROUND Previously, we compared the hyperthymic scores of residents in Sapporo, Koshigaya, and Oita (which are located at latitudes of 43°N, 36°N, and 33°N in Japan, respectively) using the Temperament Evaluation of Memphis, Pisa, Paris and San Diego-auto questionnaire version (TEMPS-A). We found that residents who lived at lower latitudes had higher hyperthymic temperament scores; however, the mechanism of the effect of latitude on hyperthymic temperament remained unclear. The current study examined the mediators of the latitude effect in additional regions with different annual temperatures and amounts of ambient sunshine. METHODS The Japanese archipelago stretches over 4000 km from north to south and has four large islands: Hokkaido, Honshu, Shikoku, and Kyushu. In addition to the TEMPS-A previously reported data collected at Sapporo (latitude 43°N), Koshigaya (36°N), and Oita (33°N), we collected the TEMPS-A data of 189 and 106 residents from Takaoka (36°N) and Obihiro (42°N), respectively. Taken together, these five regions have different patterns (i.e., highs and lows) of annual ambient total sunshine (hours) and mean temperature (°C). The effect of latitude, sunshine, and temperature on affective temperaments was analyzed for five Japanese regions. RESULTS Multiple regression analyses revealed that latitude predicted significant variance in hyperthymic temperament. Ambient temperature, but not sunshine, significantly affected hyperthymic temperament. LIMITATIONS The light exposure that residents actually received was not measured. The number of regions studied was limited. The findings might not generalize to residents across Japan or other countries. CONCLUSIONS The present findings suggest that latitude affects hyperthymic temperament, and ambient temperature might mediate this effect.

Abstract
Excited states in the N=102 isotones 166Gd and 164Sm have been observed following isomeric decay for the first time at RIBF, RIKEN. The half-lives of the isomeric states have been measured to be 950(60) and 600(140) ns for 166Gd and 164Sm, respectively. Based on the decay patterns and potential energy surface calculations, including β6 deformation, a spin and parity of 6- has been assigned to the isomeric states in both nuclei. Collective observables are discussed in light of the systematics of the region, giving insight into nuclear shape evolution. The decrease in the ground-band energies of 166Gd and 164Sm (N=102) compared to 164Gd and 162Sm (N=100), respectively, presents evidence for the predicted deformed shell closure at N=100.

Abstract
Delayed γ-ray cascades, originating from the decay of (6⁺) isomeric states, in the very neutron-rich, semimagic isotopes (136,138)Sn have been observed following the projectile fission of a ²³⁸U beam at RIBF, RIKEN. The wave functions of these isomeric states are proposed to be predominantly a fully aligned pair of f(7/2) neutrons. Shell-model calculations, performed using a realistic effective interaction, reproduce well the energies of the excited states of these nuclei and the measured transition rates, with the exception of the B(E2;6⁺→4⁺) rate of ¹³⁶Sn, which deviates from a simple seniority scheme. Empirically reducing the νf(7/2)(2) orbit matrix elements produces a 4₁⁺ state with almost equal seniority 2 and 4 components, correctly reproducing the experimental B(E2;6⁺→4⁺) rate of ¹³⁶Sn. These data provide a key benchmark for shell-model interactions far from stability.

Abstract
Patients with major depressive disorder (MDD) are known to present with cognitive deficits; however, the presence of these deficits in the remitted state have been inconsistent. One of the most important factors potentially contributing to inconsistencies between studies may be the influence of medications. To explore the influence of antidepressants on cognitive performance in remitted MDD, we evaluated memory and executive functions using Wechsler Memory Scale-Revised and Stroop Color and Word Test, and compared performance among 50 medicated (29 treated with tricyclic antidepressants [TCA], 21 treated with selective serotonin reuptake inhibitors or serotonin noradrenalin reuptake inhibitors) and 19 medication-free MDD patients and 31 controls. The results showed that all 3 MDD groups had significantly lower performance for verbal memory compared with controls. Both medicated groups showed significantly lower performance for visual memory compared with controls; however, the medication-free group did not differ from controls. For the executive function, only the TCA group showed a significantly lower performance compared with controls. These results suggest that cognitive impairment remained even in remitted patients with MDD, however, part of this impairment may be influenced by class-specific antidepressant side effects.

Abstract
A new isomer with a half-life of 23.0(8) ms has been identified at 2406 keV in (126)Pd and is proposed to have a spin and parity of 10(+) with a maximally aligned configuration comprising two neutron holes in the 1h(11/2) orbit. In addition to an internal-decay branch through a hindered electric octupole transition, β decay from the long-lived isomer was observed to populate excited states at high spins in (126)Ag. The smaller energy difference between the 10(+) and 7(-) isomers in (126)Pd than in the heavier N=80 isotones can be interpreted as being ascribed to the monopole shift of the 1h(11/2) neutron orbit. The effects of the monopole interaction on the evolution of single-neutron energies below (132)Sn are discussed in terms of the central and tensor forces.

Abstract
The half-lives of 20 neutron-rich nuclei with Z=27-30 have been measured at the RIBF, including five new half-lives of (76)Co(21.7(-4.9)(+6.5) ms), (77)Co(13.0(-4.3)(+7.2) ms), (79)Ni(43.0(-7.5)(+8.6) ms), (80)Ni(23.9(-17.2)(+26.0) ms), and (81)Cu(73.2 ± 6.8 ms). In addition, the half-lives of (73-75)Co, (74-78)Ni, (78-80)Cu, and (80-82)Zn were determined with higher precision than previous works. Based on these new results, a systematic study of the β-decay half-lives has been carried out, which suggests a sizable magicity for both the proton number Z = 28 and the neutron number N=50 in (78)Ni.

Abstract
The isoscalar monopole response has been measured in the unstable nucleus (68)Ni using inelastic alpha scattering at 50A MeV in inverse kinematics with the active target MAYA at GANIL. The isoscalar giant monopole resonance (ISGMR) centroid was determined to be 21.1 ± 1.9 MeV and indications for a soft monopole mode are provided for the first time at 12.9 ± 1.0 MeV. Analysis of the corresponding angular distributions using distorted-wave-born approximation with random-phase approximation transition densities indicates that the L = 0 multipolarity dominates the cross section for the ISGMR and significantly contributes to the low-energy mode. The L=0 part of this low-energy mode, the soft monopole mode, is dominated by neutron excitations. This demonstrates the relevance of inelastic alpha scattering in inverse kinematics in order to probe both the ISGMR and isoscalar soft modes in neutron-rich nuclei.

Abstract
Cross sections of 1n-removal reactions from the neutron-rich nucleus (37)Mg on C and Pb targets and the parallel momentum distributions of the (37)Mg residues from the C target have been measured at 240 MeV/nucleon. A combined analysis of these distinct nuclear- and Coulomb-dominated reaction data shows that the (37)Mg ground state has a small 1n separation energy of 0.22(-0.09)(+0.12) MeV and an appreciable p-wave neutron single-particle strength. These results confirm that (37)Mg lies near the edge of the "island of inversion" and has a sizable p-wave neutron halo component, the heaviest such system identified to date.

Abstract
BACKGROUND In a previous study examining the association of hyperthymic temperament and daily light exposure (illuminance), we compared hyperthymic scores of the Temperament Evaluation of Memphis, Pisa, Paris and San Diego-auto questionnaire version (TEMPS-A) acquired from residents in Sapporo and Oita in Japan, which are located at 43° and 33° of latitude. We found that residents of Oita had significantly higher hyperthymic scores than residents of Sapporo. Moreover, a comparison of 3 regions rather than 2 regions may show a dose-response relationship in hyperthymic temperament and illuminance. METHODS Japan has 4 large islands-Hokkaido, Honshu, Shikoku, and Kyushu. Sapporo is in Hokkaido and Oita is in Kyushu. As the 3rd location, we recently collected TEMPS-A data from 125 residents in Koshigaya which is located in Honshu at 36°. We combined the data of the Koshigaya residents with the data of 94 residents from Sapporo and 95 from Oita. RESULTS The mean yearly total sunshine of the past 20 years (1993-2012) was 1684.6h in Sapporo, 1862.9h in Koshigaya, and 2002.9h in Oita. Multiple regression analyses revealed that sunshine predicted significant variance of hyperthymic temperament in a dose-dependent manner. LIMITATIONS The limitation of the present study is the lack of the consideration of the effects of temperature on hyperthymic temperament. Since correlations are fairly small, other factors are also at work for hyperthymic temperament. CONCLUSIONS The present findings suggest that higher illuminance may maintain hyperthymic temperament via light effects in a dose-dependent manner.

Abstract
BACKGROUND Although the Temperament Evaluation of Memphis, Pisa, Paris and San Diego-auto questionnaire (TEMPS-A) was designed to identify temperaments which derive from traits but not states, there is a possibility that TEMPS-A scores might be affected by mental state in non-clinical populations. For the purpose of clarifying the effects of mental state on TEMPS-A scores, it is worthwhile to examine associations of the full version of the TEMPS-A with various depressive scales and, if possible, mania rating scales. METHODS TEMPS-A data acquired from 314 medical students and staff was used to investigate the association of temperament scores with mental assessment scores such as the Beck Depression Inventory (BDI), the Quick Inventory of Depressive Symptomatology Self-Report Japanese version (QIDS-SR-J), the Patient Health Questionnaire-9 (PHQ-9), the Hamilton Depression rating scale (HAM-D) and the Young Mania Rating Scale (YMRS). RESULTS Depressive state scores were significantly and positively associated with depressive, anxious, cyclothymic, and irritable temperament scores of TEMPS-A whereas sub-threshold hypomanic state scores were significantly and positively associated with irritable temperament of TEMPS-A. There was no association between depressive state or sub-threshold hypomanic state and hyperthymic temperament scores. LIMITATIONS The nature of the present study is cross-sectional, and it is unknown whether depressive and/or sub-threshold hypomanic states may have affected temperament scores or whether temperament scores might have affected depressive and/or sub-threshold hypomanic scores. Other limitations are that the sample may not represent the entire population and that there is no evidence that Japanese findings can be applicable outside Japan. CONCLUSIONS It is worthwhile to consider the effects of mental state on temperament scores of TEMPS-A even in non-clinical population.

Abstract
The halo structure of 31Ne is studied using 1n-removal reactions on C and Pb targets at 230 MeV/nucleon. A combined analysis of the cross sections of these nuclear and Coulomb dominated reactions that feed directly the 30Ne ground-state reveals 31Ne to have a small neutron separation energy, 0.15(-0.10)(+0.16) MeV, and spin-parity 3/2-. Consistency of the data with reaction and large-scale shell-model calculations identifies 31Ne as deformed and having a significant p-wave halo component, suggesting that halos are more frequent occurrences at the neutron drip line.

Abstract
A low-lying state in 131In82, the one-proton hole nucleus with respect to double magic 132Sn, was observed by its γ decay to the Iπ=1/2- β-emitting isomer. We identify the new state at an excitation energy of Ex=1353 keV, which was populated both in the β decay of 131Cd83 and after β-delayed neutron emission from 132Cd84, as the previously unknown πp3/2 single-hole state with respect to the 132Sn core. Exploiting this crucial new experimental information, shell-model calculations were performed to study the structure of experimentally inaccessible N=82 isotones below 132Sn. The results evidence a surprising absence of proton subshell closures along the chain of N=82 isotones. The consequences of this finding for the evolution of the N=82 shell gap along the r-process path are discussed.

Abstract
Reconstruction following pharyngolaryngectomy with total esophagectomy is a challenging surgery to perform. Between April 2008 and August 2012, three types of modified gastric pull-up reconstruction procedures, including a gastric tube creation combined with a free jejunal transfer (n = 7), elongated gastric tube creation with vascular anastomoses (n = 2) and pedunculated gastric tube creation with Roux-en-Y anastomosis (n = 5), were performed after pharyngolaryngectomy with total esophagectomy. To clarify feasibility of these reconstructive methods, we retrospectively analyzed the short-term outcomes. There were no graft failures. Salivary fistulae were observed in two cases after high pharyngoenteral anastomoses due to oropharyngeal extension of hypopharyngeal cancers. Overall morbidity rate was 21.4%, and no deaths occurred. Although the operation time was shortest for pedunculated gastric tube reconstructions, morbidity rates were similar among all methods. All three types of modified gastric pull-up reconstruction procedures can be performed safely. We can choose one of these methods according to the tumor status and the patient condition, understanding advantages and disadvantages of each procedure.

Abstract
OBJECTIVE Testosterone may have a role distinct from cortisol in the pathophysiology of depression. The hypothalamus-pituitary-adrenal (HPA) axis affects the functions of sex steroid hormones through interaction with corticotropin-releasing hormone (CRH) and gonadotropin-releasing hormone (GnRH). The objective of this study was to investigate differences in serum levels of testosterone and cortisol in male and female patients with major depressive disorder (MDD). METHODS Participants included 87 inpatients with MDD at Juntendo University Koshigaya Hospital. Serum levels of testosterone and cortisol were assessed at admission. Matched controls included 128 healthy individuals. Data from MDD patients and controls were compared separately for men and women. Correlations between serum hormone levels and scores on the Hamilton Rating Scale for Depression (HAM-D) of patients were assessed by sex. Effects of various factors on testosterone and cortisol were analyzed using multiple regression analysis. RESULTS In male patients with MDD, a significant negative correlation was seen between testosterone levels and the "retardation" score of HAM-D. However, serum testosterone levels were not significantly different in either male or female MDD patients compared with controls. Serum testosterone was negatively associated with the number of depressive episodes in male patients with MDD. Serum cortisol levels in female patients were significantly increased compared with female controls with no significant correlations between cortisol levels and HAM-D scores. CONCLUSIONS The negative correlation between the sub-score of the HAM-D and testosterone may be associated with the biological pathophysiology of male depression. Findings of serum cortisol levels in women may suggest distinct characteristics of these hormones in men and women with MDD.

Abstract
Abstract
Background
Hyaluronic acid (HA) probably plays a critical role in tumorigenesis. The clinical significance of serum HA concentration in patients with hepatocellular carcinoma (HCC) remains to be elucidated. This study analysed the relationship between preoperative serum HA levels and prognosis after hepatic resection in patients with HCC.
Methods
Consecutive patients who underwent hepatic resection for HCC between September 1999 and March 2012 were included in this retrospective study. Serum HA levels were measured within 4 weeks before surgery by an immunoturbidimetric automated latex assay. The cut-off level for preoperative serum HA was validated using a time-dependent receiver operating characteristic (ROC) curve analysis. The prognostic impact of preoperative serum HA levels was analysed using Cox proportional hazards models.
Results
A total of 506 patients of median age 66 years (405 men, 80·0 per cent) were analysed. The median length of follow-up was 32 months. High serum HA levels (100 ng/ml or above) were associated with shorter recurrence-free survival (P < 0·001) (hazard ratio (HR) 1·50, 95 per cent confidence interval 1·17 to 1·93; P = 0·002) and overall survival (P = 0·001) (HR 1·46, 1·03 to 2·07; P = 0·033). In patients with HCC without severe liver fibrosis, serum HA level was correlated with multiple tumours (P = 0·039), early recurrence (P = 0·033), and poor recurrence-free (P < 0·001) and overall (P = 0·024) survival.
Conclusion
High preoperative serum HA levels predict poor prognosis in patients with HCC after hepatic resection, and may serve as a future biomarker.

Abstract
While statin intake has been proven to reduce the risk of colorectal cancer (CRC), the mechanism of antitumor effects and clinical significance in survival benefits remain unclear. Statin-induced antiproliferative effects and its underlying mechanism were examined using six CRC cell lines. Statins except pravastatin showed antiproliferative effects (simvastatin ≥ fluvastatin > atorvastatin) even though both of simvastatin and pravastatin could activate mevalonate pathways, suggesting the statin-mediated antiproliferative effects depended on non-mevalonate pathway. Indeed, statin induced p27(KIP1) expression by downregulation of histone methyltransferase enhancer of zeste homolog 2 (EZH2), which acts as an epigenetic gene silencer. Additionally, the use of simvastatin plus classII histone deacetylase (HDAC) inhibitor (MC1568) induced further overexpression of p27(KIP1) by inhibiting HDAC5 induction originated from downregulated EZH2 in CRC cells and synergistically led to considerable antiproliferative effects. In the clinical setting, Statin intake (except pravastatin) displayed the downregulated EZH2 expression and inversely upregulated p27(KIP1) expression in the resected CRC by immunohistochemical staining and resulted in the significantly better prognoses both in overall survival (p = 0.02) and disease free survival (p < 0.01) compared to patients without statin intake. Statins may inhibit tumor progression via an EZH2-mediated epigenetic alteration, which results in survival benefits after resected CRC. Furthermore, statin plus classII HDAC inhibitor could be a novel anticancer therapy by their synergistic effects in CRC.

Abstract
Radiofrequency ablation (RFA) is increasingly being used for the treatment of intrathoracic malignancies. Although RFA has been found to be promising in the treatment of lung metastases from some types of neoplasms, little is known concerning its clinical significance in the treatment of pulmonary metastasis from esophageal squamous cell carcinoma (ESCC). This retrospective study evaluated the feasibility, safety, and effectiveness of computed tomography-guided RFA for pulmonary metastasis from ESCC. A series of 10 ESCC patients with 17 pulmonary tumors were included. Correct placement of the ablation device into the target tumor proved to be feasible in all tumors (100%). The mean visual analog scale score, with values that ranged from 0 (no pain) to 10 (worst pain possible), was 1. This suggested that this procedure was well tolerated. No procedure-related deaths occurred. A pneumothorax needing drainage was a major complication in two patients. Local control of ablated tumor lasting for at least 1 year was achieved in 10 (83%) of 12 assessable tumors. Although locoregional recurrences developed in two tumors, these lesions could be recontrolled by repeat treatment with RFA. Three patients died of recurrent disease. The predicted 1- and 2-year overall survival rates after lung RFA were 77.8% and 62.2%, respectively. Percutaneous computed tomography-guided RFA yielded relatively high levels of local control in patients with pulmonary metastases from ESCC and was associated with an acceptable level of complications. It was concluded that a prospective study will be necessary to evaluate the effectiveness of a combination of systemic therapy and RFA for ESCC lung metastases.

Abstract
AIMS The aim of this study was to investigate the relationship between the use of bevacizumab (Bmab) in addition to oxaliplatin (OX), the development of sinusoidal obstruction syndrome (SOS) and the changes in splenic volume as an indicator of the protective effect of Bmab against OX-induced SOS. METHODS Seventy-nine patients who received OX-based chemotherapy with (OX + Bmab group: n = 48) or without Bmab (OX group: n = 31) for colorectal liver metastases were included in this study. The changes in splenic volume after chemotherapy were evaluated in the two groups. Furthermore, the relationship between the changes in splenic volume and SOS were analyzed in the 55 patients who underwent hepatectomy. RESULTS A significant increase in the splenic volume was observed in the OX group, but not in the OX + Bmab group. The increase in the splenic volume relative to baseline was significantly higher in the OX group than in the OX + Bmab group (39.1% vs. 2.3%, p < 0.0001). The incidence of moderate or severe SOS was significantly higher in the OX group than in the OX + Bmab group (50.0% vs. 16.0%, p = 0.0068), and the increase in the splenic volume was significantly higher in the patients with SOS than in those without SOS (42.9% vs. 9.9%, p = 0.0001). A multivariate analysis identified the increase in the splenic volume as an independent predictor of the development of SOS. CONCLUSIONS This study demonstrated that the inhibition of splenic volume enlargement might be a useful indicator of the protective effect of Bmab against OX-induced SOS.
