Abstract
Background Anti-programmed cell death protein 1 (PD-1) antibody monotherapy (PD1) has led to favorable responses in advanced non-acral cutaneous melanoma among Caucasian populations; however, recent studies suggest that this therapy has limited efficacy in mucosal melanoma (MCM). Thus, advanced MCM patients are candidates for PD1 plus anti-cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) combination therapy (PD1 + CTLA4). Data on the efficacy of immunotherapy in MCM, however, are limited. We aimed to compare the efficacies of PD1 and PD1 + CTLA4 in Japanese advanced MCM patients. Patients and methods We retrospectively assessed advanced MCM patients treated with PD1 or PD1 + CTLA4 at 24 Japanese institutions. Patient baseline characteristics, clinical responses (RECIST), progression-free survival (PFS), and overall survival (OS) were estimated using Kaplan–Meier analysis, and toxicity was assessed to estimate the efficacy and safety of PD1 and PD1 + CTLA4. Results Altogether, 329 patients with advanced MCM were included in this study. PD1 and PD1 + CTLA4 were used in 263 and 66 patients, respectively. Baseline characteristics were similar between both treatment groups, except for age (median age 71 versus 65 years; P < 0.001). No significant differences were observed between the PD1 and PD1 + CTLA4 groups with respect to objective response rate (26% versus 29%; P = 0.26) or PFS and OS (median PFS 5.9 months versus 6.8 months; P = 0.55, median OS 20.4 months versus 20.1 months; P = 0.55). Cox multivariate survival analysis revealed that PD1 + CTLA4 did not prolong PFS and OS (PFS: hazard ratio 0.83, 95% confidence interval 0.58-1.19, P = 0.30; OS: HR 0.89, 95% confidence interval 0.57-1.38, P = 0.59). The rate of ≥grade 3 immune-related adverse events was higher in the PD1 + CTLA4 group than in the PD1 group (53% versus 17%; P < 0.001). Conclusions First-line PD1 + CTLA4 demonstrated comparable clinical efficacy to PD1 in Japanese MCM patients, but with a higher rate of immune-related adverse events. Anti-PD-1 plus anti-CTLA-4 antibody therapy (PD1 + CTLA4) is an option for patients with advanced mucosal melanoma (MCM). Data on the efficacy of PD1 + CTLA4 compared with PD-1 monotherapy (PD1) for MCM, however, are limited. We retrospectively analyzed data from 329 Japanese patients with advanced MCM treated with PD1 or PD1 + CTLA4. No significant differences in objective response rate, progression-free survival, or overall survival were observed. Immune-related adverse events resulting in treatment cessation were higher in the PD1 + CTLA4 group.

Abstract
Abstract
The high temperature gas-cooled reactor (HTGR) has advantages for irradiation applications such as large space available for irradiation at reflector region and high thermal neutron spectrum with the graphite moderator. High temperature engineering test reactor (HTTR), a prismatic type of the HTGR, has been constructed to establish and upgrade the basic technologies for the HTGRs. Many irradiation regions are reserved in the HTTR to be served as a potential tool for an irradiation test reactor in order to promote innovative basic researches such as materials, fusion reactor technology, and radiation chemistry. This study shows the overview of some possible irradiation applications at the HTTRs including neutron transmutation doping silicon (NTD-Si) and Iodine-125 (125I) productions. The HTTR has possibility to produce about 40 tons of doped Si-particles per year for fabrication of spherical silicon solar cell. Besides, the HTTR could also produce about 1.8 × 105 GBq/yr of 125I isotope, comparing to 3.0 × 103 GBq of total 125I supplied in Japan in 2016.

Abstract
Abstract
Background
Sodium-glucose cotransporter 2 (SGLT2) inhibitor promotes diuresis and reduces the risk of hospitalization for heart failure (HF). However, the mechanisms of diuretic effects of SGLT2 inhibitor in HF patients with type 2 diabetes mellitus (T2DM) remain under investigation.
Purpose
The purpose of this study was to investigate the mechanisms of acute diuretic effects of SGLT2 inhibitor and to identify its predictor in HF patients with T2DM.
Methods
We prospectively enrolled 40 hospitalized HF patients with T2DM (68±13 years, 63% male, and hemoglobin A1c 7.1±0.9%) between July 2014 and June 2018. All patients received ipragliflozin at a dose of 50 mg once daily after breakfast. They underwent 24-hour urine test and first-morning blood and urine tests before and after ipragliflozin therapy.
Results
Urine volume significantly increased from 1,365±511 ml/day on day 0 to 1,698±595 ml/day on day 3 (p<0.001). Multivariate linear regression analyses showed that the increase of 24-hour urine sodium but not urine sugarwas significantlyand independently associated with the increase of 24-hour urine volume (β-Coefficient=0.80; P<0.001). Univariate and multivariate logistic regression analyses showed that higher dosage of furosemide-equivalent loop diuretics and lower level of first-morning urine sodium concentration (per 1 mEq/L) at baseline were significantly associated with the diuretic effect of ipragliflozin therapy, and the latter independently predicted increase of 24-hour urine volume (Table).
Predictors for increase of urine volume Univariate Multivariate Odds ratio (95% CI) P value Odds ratio (95% CI) P value Dosage of furosemide, mg 1.09 (1.01–1.18) 0.04 – – HbA1c, % 1.45 (0.56–3.78) 0.44 Fasting blood glucose, mg/dL 1.02 (0.99–1.04) 0.24 eGFR, mL/min/1.73m2 1.01 (0.97–1.05) 0.65 Plasma BNP, pg/mL 1.00 (0.99–1.01) 0.12 Left ventricular ejection fraction, % 0.98 (0.94–1.02) 0.24 First-morning urine sugar, mg/dL 1.20 (0.96–1.50) 0.12 First-morning urine sodium, mEq/L 0.96 (0.93–0.99) 0.02 0.96 (0.93–0.99) 0.02 24-hour urine sugar, g/day 3.49 (0.13–93.40) 0.46 24-hour urine sodium, mEq/day 0.98 (0.96–1.01) 0.20 eGFR, estimated glomerular filtration rate; BNP, brain natriuretic peptide.
Conclusion
SGLT2 inhibitor has acute natriuretic activity and may restore loop-diuretic resistance in HF patients with T2DM.

Abstract
Abstract
Background
Inflammatory bowel disease (IBD) is a complex multisystem disease characterized by chronic inflammation, which can lead to coronary microvascular dysfunction (CMD).
Purpose
We aimed to investigate the presence and the severity of CMD in Crohn's disease (CD) and ulcerative colitis (UC) by assessing coronary flow reserve (CFR) using transthoracic Doppler echocardiography, and to elucidate the influence of enterectomy on CMD.
Methods
Thirty-seven IBD patients (22 CD patients: 39±12 years, 15 UC patients: 52±17 years), and 30 age- and gender-matched control subjects (46±12 years) who have comparable risk factors for coronary artery disease were enrolled. Smokers were excepted from the present study. For CFR measurement, coronary flow velocity was recorded at rest and during hyperemia in the left anterior descending coronary artery induced by intravenous infusion of adenosine triphosphate (0.14 mg/kg/min), and a CFR ≤2.5 calculated as the ratio of hyperemic to basal peak and mean diastolic velocity defined CMD. CFR measurement was repeated before and within 1 year after enterectomy. Serum or plasma cytokines were also measured before and after enterectomy.
Results
The median disease duration of CD and UC patients were 12 and 6 years. Although none of control subjects had CMD, 38% in IBD patients (CD: 41%, UC: 33%) had CMD. CFR was similarly and significantly lower in CD and UC patients than Control subjects (CD: 2.92±1.03*, UC: 2.99±0.65*, and Control: 3.84±0.75, *p<0.05 vs. Control). Serum levels of TNF-α, IL-6 and hs-CRP were significantly higher in CD and UC patients than Control subjects. Multiple linear regression analysis showed that the presence of IBD and mean diastolic flow velocity at baseline were independently associated with reduced CFR among all study participants (β=−0.324 and −0.614, p=0.001, respectively). CFR in IBD patients with both CMD and non-CMD significantly improved after enterectomy, and the extent of CFR improvement was greater in patients with CMD than those with non-CMD (Figure). Serum levels of IL-6 and hs-CRP significantly reduced among all IBD patients.
Conclusion
IBD was associated with CMD, which improved after enterectomy.

Abstract
Tyrosine kinase inhibitors (TKI) are used for primary therapy in patients with newly diagnosed CML. However, a reliable method for optimal selection of a TKI from the viewpoint of drug sensitivity of CML cells has not been established. We have developed a FRET-based drug sensitivity test in which a CrkL-derived fluorescent biosensor efficiently quantifies the kinase activity of BCR-ABL of living cells and sensitively evaluates the inhibitory activity of a TKI against BCR-ABL. Here, we validated the utility of the FRET-based drug sensitivity test carried out at diagnosis for predicting the molecular efficacy. Sixty-two patients with newly diagnosed chronic phase CML were enrolled in this study and treated with dasatinib. Bone marrow cells at diagnosis were subjected to FRET analysis. The ΔFRET value was calculated by subtraction of FRET efficiency in the presence of dasatinib from that in the absence of dasatinib. Treatment response was evaluated every 3 months by the BCR-ABL1 International Scale. Based on the ΔFRET value and molecular response, a threshold of the ΔFRET value in the top 10% of FRET efficiency was set to 0.31. Patients with ΔFRET value ≥0.31 had significantly superior molecular responses (MMR at 6 and 9 months and both MR4 and MR4.5 at 6, 9, and 12 months) compared with the responses in patients with ΔFRET value <0.31. These results suggest that the FRET-based drug sensitivity test at diagnosis can predict early and deep molecular responses. This study is registered with UMIN Clinical Trials Registry (UMIN000006358).

Abstract
Background Oxidative stress mitigated by antioxidant enzymes is thought to be involved in the progression to castration-resistant prostate cancer (CRPC) during androgen-deprivation therapy (ADT). This study investigated the association between genetic variations in antioxidant enzymes and the efficacy of ADT as well as its biological background. Patients and methods The non-synonymous or promoter-locating polymorphisms of antioxidant enzymes were examined as well as the time to CRPC progression and overall survival in 104 and 92 patients treated with ADT for metastatic and non-metastatic prostate cancer, respectively. In addition, intracellular reactive oxygen species and expression levels of antioxidant enzymes were examined in castration-resistant and enzalutamide-resistant cells. Results In metastatic prostate cancer, the AG/GG allele in GSTM3 rs7483 and CT/TT allele in CAT rs564250 were associated with a significantly lower risk of progression to CRPC and all-cause death compared with homozygotes of the major AA allele (hazard ratio [HR]; [95% confidence interval (CI)], 0.55 [0.34-0.86], P = 0.0086) and CC allele (HR; [95% CI], 0.48 [0.24-0.88], P = 0.016), respectively. On multivariate analyses, only GSTM3 rs7483 was associated with significant progression risk (AG/GG versus AA; HR; [95% CI], 0.45 [0.25-0.79], P = 0.0047) even after Bonferroni adjustment. In non-metastatic prostate cancer, the AG/GG allele in GSTM3 rs7483 was associated with a significantly lower risk of progression to CRPC (HR; [95% CI], 0.35 [0.10-0.93], P = 0.034) and all-cause death (HR; [95% CI], 0.26 [0.041-0.96], P = 0.043) compared with the AA allele. Intracellular reactive oxygen species levels were increased, accompanied with augmented GSTM3 expression in both castration-resistant and enzalutamide-resistant cells. Conclusions Differential activity of antioxidant enzymes caused by the polymorphism in GSTM3 may contribute to resistance to hormonal therapy through oxidative stress. The GSTM3 rs7483 polymorphism may be a promising biomarker for prostate cancer patients treated with ADT.

Abstract
INTRODUCTION An analysis of the activated partial thromboplastin time (APTT) in major orthopedic surgery patients receiving edoxaban for the prevention of venous thromboembolism (VTE) was carried out. METHODS The APTT waveform was analyzed in the above patients to monitor edoxaban administration. RESULTS Of these 99 patients, 12 exhibited deep vein thrombosis, and 25 had massive bleeding. An increased biphasic pattern of the APTT waveform was observed after the administration of edoxaban, but there were no significant differences between the patients with and without complications. The peak times of acceleration, velocity, and 1/2 fibrin formation were significantly prolonged after the administration of edoxaban, especially in patients with massive bleeding, and were moderately correlated with the anti-Xa activity. While the heights of velocity and acceleration peak 2 were lower in patients receiving warfarin treatment than in those receiving edoxaban, the widths of these parameters were significantly longer. The height of 1/2 fibrin formation and the width of acceleration peaks 1 and 2 and the velocity were significantly increased after the administration of edoxaban. CONCLUSION The peak time of the APTT waveform was significantly prolonged after the administration of edoxaban. The analysis of the APTT waveform may therefore be useful for the prediction of the risk of massive bleeding.

Abstract
Manganese-56 (56Mn) is among the predominant radioisotopes produced in soil by neutrons from atomic bombs. Previously, we examined the effects of the internal exposure of this radioisotope in Wistar rats and reported significant pathological changes in the lung and small intestine. In the present study, we focused on its effects on hyaluronan synthase 2 (Has2) gene expression that may related to pathological changes in the lung. Ten-week-old male Wistar rats were exposed to neutron-activated 56MnO2 powder, non-radioactive MnO2 powder or external 60Co γ-rays (2 Gy, whole body). Animals were examined on days 3, 14, and 60 post-exposure. Absorbed doses in the lung of rats exposed to 56Mn were 55-110 mGy. Quantitative reverse transcription polymerase chain reaction analysis revealed that 56Mn exposure significantly reduced the expression of Has2 gene in the lung, while γ-rays did not change it. Our findings suggest that internal exposure to 56Mn, even at low doses, has a significant biological impact on the lung compared with external radiation.

Abstract
BACKGROUND While the frequency of interleukin (IL)-10-producing B (B10) cells is reported to have an inverse correlation with disease activity in some human autoimmune diseases, the association between B10 cells and autoimmune blistering diseases (AIBD) has not been well evaluated. Although several phenotypes of human regulatory B cells have been proposed, the most appropriate one in AIBD has not been established. OBJECTIVE To evaluate B10 cells in AIBD including their phenotypes. METHODS Peripheral blood mononuclear cells were isolated from 39 patients with AIBD, including 14 with pemphigus and 25 with pemphigoid, and 10 healthy controls. We investigated the frequencies of B10 cells and CD19+ CD24hi CD38hi B cells using flow cytometry. RESULTS The frequencies of B10 cells and CD19+ CD24hi CD38hi B cells were significantly lower and higher, respectively, in patients with pemphigus compared with healthy controls. Comparing patients with pemphigoid and healthy controls, no significant difference in the frequencies of B10 cells and CD19+ CD24hi CD38hi B cells was observed. B10-cell level in pemphigus was not associated with disease severity but inversely correlated with the required dose of steroid for treatment. While no significant difference in the frequency of IL-10-producing cells among CD19+ CD24hi CD38hi B cells was observed, in CD9+ and CD27- B-cell subsets it was significantly decreased in patients with pemphigus compared with healthy controls. CONCLUSIONS Our results suggest the association of B10 cells with pemphigus but not with pemphigoid. The decrease in B10-cell level in pemphigus is partly caused by the lower production of IL-10 in CD9+ and CD27- B-cell subsets.

Abstract
The high-temperature engineering test reactor (HTTR) is a block-type high-temperature gas-cooled reactor (HTGR). There are 32 control rods (16 pairs) in the HTTR. Six of the pairs of control rods are located in a core region and the remainder are located in a reflector region surrounding the core. Inserting all control rods simultaneously at the reactor scram in a full-power operation presents difficulty in maintaining the integrity of the metallic sleeve of the control rod because the core temperature of the HTTR is too high. Therefore, a two-step control rod insertion method is adopted for the reactor scram. The calculated control rod worth at the first step showed a larger underestimation than the measured value in the second step, although the calculated results of the excess reactivity tests showed good agreement with the measured result in the criticality tests of the HTTR. It is concluded that a cell model for the control rod guide block with the control rod in the reflector region is not suitable. In addition, in the core calculation, the macroscopic cross section of a homogenized region of the control rod guide block with the control rod is used. Therefore, it would be one of the reasons that the neutron flux distribution around the control rod in control rod guide block in the reflector region cannot be simulated accurately by the conventional cell model. In the conventional cell model, the control rod guide block is surrounded by the fuel blocks only, although the control rods in the reflector region are surrounded by both the fuel blocks and the reflector blocks. The difference of the neutron flux distribution causes the large difference of a homogenized macroscopic cross-section set of the control rod guide block with the control rod. Therefore, in this paper, the cell model is revised for the control rod guide block with the control rod in the reflector region to account for the actual configuration around the control rod guide block in the reflector region. The calculated control rod worth at the first step using the improved cell model shows better results than the previous one.

Abstract
The high-temperature engineering test reactor (HTTR) is a block-type high-temperature gas-cooled reactor (HTGR), which was constructed in Japan. The operating data of HTTR with burn-up to about 370 EFPD (effective full-power days), which are very important for the development of HTGRs, have been collected in both zero-power and powered operations. In the aspects of code validation, the detailed prediction of temperature distribution in the core makes it difficult to validate the calculation code because of difficulty in measuring the core temperature directly in powered operation of the HTTR. In this study, the measured data of the control rod position, while keeping the temperature distribution in the core uniform at criticality in zero-power operation at the beginning of each operation cycle were compared with the calculated results by core physics design code of the HTTR. The measured data of the control rod position were modified based on the core temperature correlation. At the beginning of burn-up, the trends of burn-up characteristics are slightly different between experimental and calculation data. However, the calculated result shows less than 50 mm of small difference (total length of control rod is 4060 mm) to the measured one, which indicates that the calculated results appropriately reproduced burn-up characteristics, such as a decrease in uranium-235, accumulation in plutonium, and decrease in burnable absorber.

Abstract
BACKGROUND Neutrophil elastase plays an important role in skin inflammation induced by neutrophil infiltration. Elafin is an inducible elastase inhibitor expressed by keratinocytes, and is known to be involved in pathogenesis of neutrophilic skin disorders such as psoriasis. METHODS Immunohistochemical studies of elafin expression in the cases of vasculitis were performed. Induction of elafin expression in cultured vascular cells and its effect on neutrophil migration were studied in vitro. RESULTS A positive immunoreactivity was detected in polyarteritis nodosa, giant cell arteritis and Schönlein-Henoch purpura, but no immunoreactivity was found in Churg-Strauss syndrome. Elafin expression in cultured venous endothelial cells and arterial smooth muscle cells was undetectable, but induced by interleukin-1β (IL-1β) and IL-8. Elafin inhibited the elastin peptide-induced neutrophil chemotaxis at the concentration of 10(-8) -10(-5) mol/L. CONCLUSION Elafin deposition induced by cytokines (IL-1β or IL-8) will be an important regulator for the progress of leucocytoclastic vasculitis by functioning as an inhibitor for neutrophil chemotaxis as well as for vascular elastin degradation.

Abstract
KEY POINTS Patients with transposition of the great arteries (TGA) and systemic right ventricles have premature congestive heart failure; there is also a growing concern that athletes who perform extraordinary endurance exercise may injure the right ventricle. Therefore we felt it essential to determine whether exercise training might injure a systemic right ventricle which is loaded with every heartbeat. Previous studies have shown that short term exercise training is feasible in TGA patients, but its effect on ventricular function is unclear. We demonstrate that systemic right ventricular function is preserved (and may be improved) in TGA patients with exercise training programmes that are typical of recreational and sports participation, with no evidence of injury on biomarker assessment. Stroke volume reserve during exercise correlates with exercise training response in our TGA patients, identifying this as a marker of a systemic right ventricle (SRV) that may most tolerate (and possibly even be improved by) exercise training. ABSTRACT We aimed to assess the haemodynamic effects of exercise training in transposition of the great arteries (TGA) patients with systemic right ventricles (SRVs). TGA patients have limited exercise tolerance and early mortality due to systemic (right) ventricular failure. Whether exercise training enhances or injures the SRV is unclear. Fourteen asymptomatic patients (34 ± 10 years) with TGA and SRV were enrolled in a 12 week exercise training programme (moderate and high-intensity workouts). Controls were matched on age, gender, BMI and physical activity. Exercise testing pre- and post- training included: (a) submaximal and peak; (b) prolonged (60 min) submaximal endurance and (c) high-intensity intervals. Oxygen uptake (V̇O2; Douglas bag technique), cardiac output (Q̇c, foreign-gas rebreathing), ventricular function (echocardiography and cardiac MRI) and serum biomarkers were assessed. TGA patients had lower peak V̇O2, Q̇c, and stroke volume (SV), a blunted Q̇c/V̇O2 slope, and diminished SV response to exercise (SV increase from rest: TGA = 15.2%, controls = 68.9%, P < 0.001) compared with controls. After training, TGA patients increased peak V̇O2 by 6 ± 8.5%, similar to controls (interaction P = 0.24). The magnitude of SV reserve on initial testing correlated with Q̇c training response (r = 0.58, P = 0.047), though overall, no change in peak Q̇c was observed. High-sensitivity troponin T (hs-TnT) and N-terminal prohormone of brain naturetic peptide (NT pro-BNP) were low and did not change with acute exercise or after training. Our data show that TGA patients with SRVs in this study safely participated in exercise training and improved peak V̇O2. Neither prolonged submaximal exercise, nor high-intensity intervals, nor short-term exercise training seem to injure the systemic right ventricle.
