Abstract
Aqueous galactose solutions containing eggshell was heated at 120 °C to produce calcium supplements containing rare sugars. Galactose was isomerized to rare sugars with improving rare sugar yields compared to those without eggshell. Organic acids were also formed as byproducts during the reaction. These acids were neutralized by dissolving eggshells with increasing the calcium ion concentration in the solution. When eggshell components (calcium carbonate, magnesium carbonate, or calcium phosphate) were used for the treatment, rare sugars were also formed. Especially, addition of magnesium carbonate improved rare sugar yield, but byproduct formation became more pronounced. Eggshells used in the treatment were used for repeated treatments. When eggshells were used three times, rare sugar yield changed only slightly but the selectivity of rare sugars improved significantly. By these processes, we obtained an aqueous solution of rare sugars containing calcium ion at 295 mg/L, which has potential as ingredients for dietary supplements.

Abstract
Galactose was treated in sodium phosphate buffer at various concentrations (0.1-500 mmol/L) under subcritical water conditions (140 °C), and the effects of the buffer concentration and reaction time (0-300 s) on the reaction behavior were evaluated. The reaction proceeded rapidly at higher buffer concentrations. Rare sugars (tagatose, talose, and sorbose) were formed from galactose by isomerization. The highest yield of the main product, tagatose, was approximately 14 % in 50 mmol/L buffer. However, the tagatose yield did not increase further with increasing buffer concentration. On the other hand, the formation of talose and sorbose was accelerated at higher buffer concentrations, with the highest yields of approximately 5 % and 12 %, respectively, in 500 mmol/L buffer. At the same time, the formation of byproducts (organic acids and colored substances) was also accelerated in high-concentration buffers. These results suggest that phosphate buffer promoted all reactions occurring under subcritical water conditions.

Abstract
BACKGROUND We evaluated whether baseline maternal heart rate variability (HRV), including the Analgesia Nociception Index (ANI), is associated with maternal hypotension and fetal heart rate (FHR) abnormalities following combined spinal-epidural (CSE) labor analgesia. METHODS Laboring women were enrolled in this prospective observational study. The primary endpoint was maternal hypotension. The secondary endpoint was FHR abnormalities within 30 min following CSE analgesia initiated with intrathecal plain bupivacaine 1.0 mg and fentanyl 20 µg. The maternal ANI, electrocardiogram, blood pressure, heart rate, oxygen saturation, and FHR tracings were recorded 15 min before and 30 min after CSE. Parturients were grouped based on presence of hypotension and FHR abnormalities. Patient demographics and HRV metrics were compared. Receiver operating characteristics (ROC) curves were constructed for the prediction of hypotension and FHR abnormalities. RESULTS No significant intergroup differences were detected in patient characteristics. Several baseline HRV metrics and ANI differed significantly between the normotensive (n = 50) and hypotensive (n = 31) groups and between parturients showing FHR abnormalities (n = 19) and those showing reassuring FHR traces (n = 62). The area under the ROC curve (AUC) for predicting hypotension of the baseline low-frequency (LF)/high-frequency (HF) ratio was 0.677 (95% CI 0.55 to 0.80), and that of the ANI was 0.858 (95% CI 0.78 to 0.94). For predicting non-reassuring FHR patterns, the AUC of the LF/HF ratio was 0.77 (95% CI 0.65 to 0.89), and that of the ANI was 0.833 (95% CI 0.72 to 0.94). CONCLUSIONS The ANI can predict the propensity for maternal hypotension and non-reassuring FHR patterns following CSE.

Abstract
BackgroundTakayasu arteritis (TAK), a granulomatous large vessel vasculitis, mainly involves the aorta and its proximal branches and commonly occurs in young females. However, studies of pregnancy in women with TAK are sparse and limited, probably due to the rarity of the disease.ObjectivesThe purpose of this study was to understand the status quo of medical treatments of the primary disease and outcomes of pregnancy in patients with TAK, and birth outcomes of the children in Japan.MethodsPatients with TAK who conceived after the onset of the disease and were managed at medical facilities participating in the Japan Research Committee of the Ministry of Health, Labour, and Welfare for Intractable Vasculitis (JPVAS) were retrospectively enrolled in this study. The following information was collected from patients who had a live-born baby: age at diagnosis of TAK, disease classification, age at delivery, treatments before and during pregnancy, complications during pregnancy, birth outcomes of the children, and changes in disease activity during pregnancy and after delivery.ResultsFifty-one cases and 69 pregnancies from 19 ethics committee-approved centers were enrolled during the study period 2019–2021. Of these, 49 cases and 66 pregnancies (95.7%) resulted in delivery and live-born babies. The Numano classification of the 49 cases was as follows: type I, 11; type IIa, 15; type IIb,12; type III, 1; type IV, 1; type V, 9; with type IIa being the most common. The age of diagnosis was 22 years (13–37 years, year of diagnosis 1965–2017), the median age of the delivery of 66 pregnancies was 31 years (year of delivery 1969-2021), and the median duration of illness at delivery was nine years. There were 34 planned pregnancies (51.5%, including four pregnancies by artificial insemination/ovulation induction). Preconception therapy included prednisolone (PSL) in 51 pregnancies (77.3%, median dose 7.5 mg (range 4–30 mg)/day), immunosuppressive drugs in 18 pregnancies (27.3%, azathioprine 8, tacrolimus 7, methotrexate 4, cyclosporin A 1, and colchicine 1), biologics in 12 pregnancies (18.1%, infliximab 6, tocilizumab 5, and adalimumab 1), antihypertensive drugs in 5 pregnancies (7.6%). Surgical treatment had been performed before pregnancy in 6 cases (aortic root replacement 2, subclavian artery dilatation 1, subclavian artery bypass 1, subclavian artery stenting 1, and ascending aorta semicircular artery replacement 1). Medications used during the course of pregnancy included PSL in 48 pregnancies (72.7%, median dose 8 mg (range 4–30 mg)/day, increased in 13 pregnancies, decreased in 1 pregnancy), immunosuppressants in 13 pregnancies (19.7%, azathioprine 6, tacrolimus 6, and cyclosporin A 1), biologics 9 pregnancies (13.6%, infliximab 4, tocilizumab 4, and adalimumab 1). Immunosuppressants and biologics were discontinued in five and four pregnancies after conception. Complications during pregnancy were observed in 20 pregnancies (30.3%), with hypertension being the most common. Complications related to TAK or its treatment were severe infections in two pregnancies and aneurysm enlargement due to increased circulating plasma volume in one pregnancy. Aortic arch replacement was performed after delivery for the latter case. Relapse of TAK was observed in 4 pregnancies (6.1%) during pregnancy and in 8 pregnancies (12.1%) after delivery. One pregnancy resulted in restenosis of subclavian artery for which dilatation procedure was performed prior to the pregnancy. There were 13/66 (19.7%) preterm infants and 17/59 (28.8%) low birth weight infants; all but one had a birth weight of more than 2,000 g and no had serious postnatal abnormalities. Forty-three (82.7%) of the 52 confirmed infants were breastfeed fully or mixed.ConclusionMost of the pregnancies in patients with TAK were successfully delivered while they had low disease activity at a dose of less than 10 mg/day of PSL. Relapse occurred during pregnancy and after delivery in some cases. The babies tended to have low birth weight, but 82.7% of them were breastfed without serious complications.Disclosure of InterestsTakako Miyamae: None declared, Yusuke Manabe: None declared, takahiko sugihara Speakers bureau: TS has received honoraria from Abbvie Japan Co., Ltd., AsahiKASEI Co., Ltd., Astellas Pharma Inc., Ayumi Pharmaceutical, Bristol Myers Squibb K.K., Chugai Pharmaceutical Co., Ltd., Eli Lilly Japan K.K., Mitsubishi-Tanabe Pharma Co., Ono Pharmaceutical, Pfizer Japan Inc., Takeda Pharmaceutical Co.

Abstract
Myasthenia gravis (MG) is an autoantibody-mediated inflammatory disease of the neuromuscular junction. Biomarkers indicating disease activity in MG are warranted. Recently, the soluble urokinase plasminogen activator receptor (suPAR) has been reported to be associated with inflammation, tissue damage, disease activity and prognosis in various diseases, including autoimmune diseases. In this study, serum suPAR levels were measured in 40 patients with anti-acetylcholine receptor antibody-positive MG and 30 controls, and their correlations with clinical variables and severity scale scores were investigated. We identified that serum suPAR levels significantly correlated with MG activities of daily living scale (Spearman's ρ = 0·45; P = 0·004) and MG Foundation of America classification (Spearman's ρ = 0·37; P = 0·02) at serum sampling, but not with anti-acetylcholine receptor antibody titers. In conclusion, serum suPAR levels can be a candidate for a novel biomarker of disease activity in anti-acetylcholine receptor antibody-positive MG.

Abstract
BACKGROUND AND PURPOSE Metal artifacts reduce the quality of CT images and increase the difficulty of interpretation. This study compared the ability of model-based iterative reconstruction and hybrid iterative reconstruction to improve CT image quality in patients with metallic dental artifacts when both techniques were combined with a metal artifact reduction algorithm. MATERIALS AND METHODS This retrospective clinical study included 40 patients (men, 31; women, 9; mean age, 62.9 ± 12.3 years) with oral and oropharyngeal cancer who had metallic dental fillings or implants and underwent contrast-enhanced ultra-high-resolution CT of the neck. Axial CT images were reconstructed using hybrid iterative reconstruction and model-based iterative reconstruction, and the metal artifact reduction algorithm was applied to all images. Finally, hybrid iterative reconstruction + metal artifact reduction algorithms and model-based iterative reconstruction + metal artifact reduction algorithm data were obtained. In the quantitative analysis, SDs were measured in ROIs over the apex of the tongue (metal artifacts) and nuchal muscle (no metal artifacts) and were used to calculate the metal artifact indexes. In a qualitative analysis, 3 radiologists blinded to the patients' conditions assessed the image-quality scores of metal artifact reduction and structural depictions. RESULTS Hybrid iterative reconstruction + metal artifact reduction algorithms and model-based iterative reconstruction + metal artifact reduction algorithms yielded significantly different metal artifact indexes of 82.2 and 73.6, respectively (95% CI, 2.6-14.7; P < .01). The latter algorithms resulted in significant reduction in metal artifacts and significantly improved structural depictions(P < .01). CONCLUSIONS Model-based iterative reconstruction + metal artifact reduction algorithms significantly reduced the artifacts and improved the image quality of structural depictions on neck CT images.

Background/Purpose
Mitral annuloplasty plays a crucial role during mitral valve (MV) repair. The dynamics of the mitral annulus (MA) may be variously affected by the annuloplasty device. Therefore, we investigated the differences in MA dynamics when using a semi-rigid ring, semi-rigid band, and flexible ring.
Methods
We retrospectively reviewed 61 patients with mitral regurgitation who underwent MV repair, which included annuloplasty. Semi-rigid rings were used in 33 patients, flexible bands in 21, and semi-rigid bands in seven. Three-dimensional transoesophageal echocardiography (3D-TEE) images of the MV were recorded before and after annuloplasty. The 3D-TEE image datasets were analysed using semi-automated analysis software. We measured anterolateral–posteromedial (AL–PM) and anteroposterior (AP) diameter and height of the MV. The sphericity index (AP diameter divided by AL-PM diameter) and annular height to commissural width ratio (AHCWR) were calculated as the circular and saddle-shaped geometries, respectively. The differences in these values between end diastole (ED) and end systole (ES) were compared by t-test before and after mitral annuloplasty to analyse the MA among the semi-rigid ring, semi-rigid band, and flexible ring.
Results
Before annuloplasty (n = 61), the AL–PM diameter was significantly larger (ED: 4.26 ± 0.08 vs. ES: 4.24 ± 0.07, p = 0.016) and the sphericity index was significantly smaller (ED: 0.93 ± 0.01 vs. ES: 0.94 ± 0.01, p = 0.017) at ED than at ES. Table 1 shows the analysis after annuloplasty for each device. After annuloplasty, not every group demonstrated significant differences in AL–PM diameter or sphericity index. MA dynamics were reduced equally with the three devices.
Conclusion
Mitral annuloplasty reduced MA dynamics equally when using a semi-rigid ring, semi-rigid band, and flexible ring. There were no distinctive differences among the three devices in terms of maintaining flexibility and a saddle-shaped geometry.

Abstract
Abstract
Background
The most effective approach for long-standing persistent atrial fibrillation (LSPAF) ablation remained undetermined. Here, we hypothesized that selective linear ablation (SLA) according to the type of tachycardia induced by burst atrial pacing (BAP) after pulmonary venous isolation (PVI) in single-procedure reduces the recurrence.
Methods
A cohort of 66 LSPAF patients (Mean age 71.0±8.2 years, AF duration 40.5±58.8 months) who underwent PVI in single-procedure between April 2016 and November 2018 was evaluated.
Results
Any sustained atrial tachycardia (AT) or AF were not inducible by BAP after PVI in 21 patients (Non-inducible group, 31.8%, 71.3±7.9 years, 34.4±54.2 months). These patients underwent cavo-tricuspid isthmus (CTI) ablation after PVI. Forty-one patients underwent selective liner ablation according to the type of tachycardia induced by BAP after PVI (SLA group, 62.1%, 71.2±8.3 years, 39.3±55.6 months). Maccroreentry ATs (6 common atrial flutter, 5 AT originating from left atrial anterior wall, 2 peri-mitral atrial flutter, 1 roof-dependent atrial flutter) were induced by BAP in 14 patients of SLA group (73.2±19.7 years, 51.7±83.5 months). RF applications created the complete linear lesions to terminate maccroreentry ATs. Sustained AF was induced by BAP after PVI in 27 patients of SLA group (70.2±9.2 years, 32.9±31.2 months). These patients underwent posterior wall isolation (PWI) and CTI ablation. Unmappable AT was induced by BAP after PVI in 4 patients (Non-SLA group, 6.1%, 67.0±9.7 years, 84.5±105.6 months). These patients underwent PWI, CTI and mitral isthmus ablation on an empirical basis instead of SLA. Using a 90-day blanking period, the single-procedure Kaplan-Meier estimates of AT or AF event-free survival were 79% at 12 months. During follow-up (14.5±8.0 months), although 19 /21 (90.5%) of Non-inducible group patients and 33/41 (80.5%) of SLA group patients did not experience AT or AF recurrence, all of Non-SLA group patients experienced AF recurrence. There was no difference between Non-inducible group and SLA group in predicting recurrence of AT or AF (p=0.3). However, there was a difference when compared with Non-SLA group (each p<0.001). Non-SLA group was an independent powerful predictor resulting in recurrence of AF after adjusting for potential confounding factors (adjusted hazard ratio = 7.17; 95% confidence interval; 2.2–23.1, p=0.001, Wald χ2=10.9). Furthermore, in Kaplan-Meier survival curves for predicting AT or AF recurrence, Non-SLA group was the significant predictive marker of AT or AF recurrence (Log-Lank χ2=18.0, p<0.001).
Kaplan-Meier survival curves
Conclusions
In LSPAF patients without inducibility of any tachycardia after PVI, sinus rhythm was highly maintained without stepwise ablation other than CTI ablation. SLA reduced recurrence of AF in LSPAF patients with AT and AF induced after PVI. In addition, nonselective liner ablations for unmappable AT after PVI were less effective in LSPAF patients.

Abstract
Abstract
Background
Lethal-ventricular-arrhythmia (VA) could be sometimes initiated by idiopathic Premature Ventricular Contractions (PVCs) originated form inferior wall. Furthermore, J-wave elevation in inferior leads was sometimes associated with lethal-VA. However, it was unclear the relationship between these PVCs and J-wave elevation in patients with lethal-VA.
Purpose
The aim of this study was to investigate the relationship between PVCs and J-wave elevation.
Methods and results
We studied 32 patients who underwent radiofrequency (RF) ablation of idiopathic PVCs with RBBB and superior axis. These PVCs were originating from inferior wall of left ventricular. Lethal-VA was defined as ventricular fibrillation (VF) or ventricular tachycardia (VT) with loss of consciousness (LOC). Among 32 patients, 3 had VF and 2 had VT with LOC. Other 27 had non-lethal-VA. Baseline clinical characteristics were not significantly difference between lethal and non-lethal-VA. The ratio of J-wave elevation in lethal-VA was significant higher as compared to those with non-lethal-VA (5/5 (100%) vs. 3/27 (11.1%), p<0.0001). Furthermore, no patients had recurrence of lethal-VA with J wave elevation in inferior leads after RF ablation of these PVCs with RBBB and superior axis,
Conclusions
We speculated that J-wave elevation in inferior leads might be a predictor of lethal-VA initiated by PVCs with RBBB and superior axis. RF ablation of these PVCs were useful method of treating lethal-VA.

Abstract
A DEAE-dextran-MMA copolymer (DDMC)-paclitaxel (PTX) conjugate was prepared using PTX as the guest and DDMC as the host. The resistance of B16F10 melanoma cells to PTX was confirmed, while the DDMC-PTX conjugate showed excellent anticancer activity that followed the Hill equation. The robustness in the tumor microenvironment of the allosteric system was confirmed via BIBO stability. This feedback control system, explained via a transfer function, was very stable and showed the sustainability of the system via a loop, and it showed superior anti-cancer activity without drug resistance from cancer cells. The block diagram of this signal system in the tumor microenvironment used its loop transfer function G(s) and the dN(s) of the external force. This indicial response is an ideal one without a time lag for the outlet response. The cell death rate of DDMC-PTX is more dependent on the Hill coefficient n than on the Michaelis constant Km. This means that this supermolecular reaction with tubulin follows an "induced fit model".

Abstract
BACKGROUND Aspartate transaminase-to-platelet ratio index (APRI) and fibrosis-4 (FIB-4) are well known as representative indirect serum biomarkers related to liver fibrosis. The usefulness of these markers for the diagnosis of liver fibrosis after liver transplantation (LT) in hepatitis C virus (HCV)-infected patients and the influence of splenectomy were investigated. METHODS From June 2003 to May 2014, 31 HCV-infected patients who underwent LT and postoperative follow-up liver biopsies were included in this study. The association between liver fibrosis and serum biomarkers and the influence of splenectomy on APRI and FIB-4 were also investigated. RESULTS A total of 195 biopsy specimens were collected, and liver fibrosis was identified as: F0, 59.7%; F1, 34.1%; and F2, 6.3%. Both APRI and FIB-4 were significantly higher in patients who showed F1 and F2 in liver biopsy specimen than F0 (P values, .009 and .022, respectively); sensitivity and specificity of APRI were, respectively, 63.4% and 66.7%, and those of FIB-4 were 57.7% and 69.6%. In 11 patients (35.5%) who underwent splenectomy at the time of LT, the cutoff values for APRI and FIB-4 were 0.61 and 1.41, which were significantly lower than the corresponding values (1.00 and 3.64) of patients without splenectomy. CONCLUSIONS APRI and FIB-4 could effectively estimate liver fibrosis after LT for HCV-related liver disease. For LT patients with splenectomy, APRI and FIB-4 were also useful to estimate liver fibrosis, but the standard values should be adjusted lower than those for patients without splenectomy.

Abstract
A methodology of a preventive radioecological assessment of the territory has been developed for optimizing post-emergency monitoring and countermeasure implementation in an event of a severe radiation accident. Approaches and main stages of integrated radioecological zoning of the territory are described. An algorithm for the assessment of the potential radioecological criticality (sensitivity) of the area is presented. The proposed approach is validated using data of the dosimetric passportization in Ukraine after the Chernobyl accident for the test site settlements.

Abstract
A 48-year-old Japanese woman was diagnosed with Budd-Chiari syndrome and transferred for possible living donor liver transplantation (LDLT). Examinations before LDLT revealed that the recipient had anti-Jra and preformed donor-specific anti-human leukocyte antigen (HLA) antibodies (DSA). Rituximab was administrated at 16 days prior to the patient's scheduled LDLT for the prophylaxis of antibody-mediated rejection by DSA. The clinical significance of anti-Jra has not been clearly established because of the rarity of this antibody, so we discussed blood transfusion strategy with the Department of Blood Transfusion Service and prepared for Jra-negative packed red blood cells (RBCs). Intraoperative blood salvage was used during LDLT procedures to reduce the use of packed RBCs. Although post-transplantation graft function was excellent, a total of 44 U of Jra-negative RBCs were transfused during the entire perioperative period. Because sufficient amounts of Jra-negative packed RBCs were supplied, Jra mismatched blood transfusion was avoided. The patient was discharged from our hospital on postoperative day 102 without clinical evidence of any blood transfusion-related adverse events. Although there are some controversies of blood transfusion related to anti-Jra antibodies, the current strategies of blood transfusion for liver transplantation with anti-Jra are as follows: (1) sufficient supply and transfusion of Jra-negative matched packed RBCs and (2) application of intraoperative blood salvage to reduce the total amount of rare blood type RBCs. These strategies may be changed when the mechanism of anti-Jra alloimmunization is fully understood in the future.

Abstract
BACKGROUND Impaired exercise capacity and muscle weakness are important characteristics of liver transplantation recipients. Perioperative rehabilitation has been introduced to promote early mobilization of patients and to prevent postoperative pulmonary complications. However, it is unknown how physical status recovers during the hospital stay after a liver transplant. The purpose of this study was to evaluate the changes in clinical indicators that represent the functional exercise capacity and muscle strength before and after living donor liver transplantation (LDLT). METHODS We retrospectively reviewed 21 consecutive patients who underwent LDLT with perioperative rehabilitation from April 2014 to December 2015. Twelve patients who were tested for 6-minute walk distance, hand-grip strength, and isometric knee extensor muscle strength before and 4 weeks after LDLT were enrolled. RESULTS At the preoperative baseline, the 6-minute walk distance significantly correlated with the Model for End-stage Liver Disease score and pulmonary functions (vital capacity, forced vital capacity, and forced expiratory volume in 1 second of predictive values). Comparisons between the preoperative and postoperative values revealed significant decreases in weight, Barthel Index, hand-grip strength, and isometric knee extensor muscle strength. Changes in hand-grip strength and isometric knee extensor muscle strength after LDLT correlated with the preoperative Model for End-stage Liver Disease score. CONCLUSIONS Physical functional status had not been fully recovered 4 weeks after LDLT. Further investigation regarding developing a strategy for prevention of muscle atrophy before LDLT and recovery of physical fitness after LDLT would be helpful.

Abstract
BACKGROUND This prospective study was designed to examine the associations of demographic, clinical, psychological and neuroendocrine factors with acute and chronic post-operative pain following partial mastectomy. METHODS Sixty-four female patients scheduled for partial mastectomy were enrolled. Pre-operative anxiety/depression was assessed, using the Hospital Anxiety and Depression Scale (HADS). Pre-operative 24-h urinary cortisol levels were measured 2 days before surgery. Post-operative pain was examined using a visual analog scale (VAS) for acute pain on 0-2 post-operative day (POD), and a short-form McGill Pain Questionnaire for chronic pain at 6 months after surgery. In the last 29 subjects, post-operative 24-h urinary cortisol levels were also measured on 0 POD and were subjected to correlation analysis. RESULTS Multivariate logistic regression analysis revealed that lower pre-operative cortisol secretion and greater pre-operative anxiety were significantly associated with an increased risk of moderate to severe acute post-operative pain [Odds Ratio (95% Confidence Interval); 0.96 (0.92-0.98), and 1.24 (1.04-1.54)], and that patients with greater pre-operative anxiety and moderate to severe acute pain were more likely to develop chronic post-operative pain [OR (95% CI); 1.63 (1.23-2.40), and 5.07 (1.30-24.6)]. Correlational analysis demonstrated that the post-operative cortisol level was inversely correlated with pre-operative anxiety and the intensity of acute post-operative pain (r = -0.40, p < 0.05, and r = -0.50, p < 0.01), but not with the intensity of chronic pain. CONCLUSIONS This study confirms that pre-operative anxiety is associated with both acute and chronic post-operative pain after partial mastectomy. It also suggests that lower perioperative cortisol secretion might be associated with greater acute post-operative pain. SIGNIFICANCE Although the associations between psychological stress/stress hormone levels and chronic post-operative pain remain to be determined, pre-operative psychological stress and perioperative cortisol levels are correlated with acute post-operative pain.

Abstract
BACKGROUND To understand the impact of psychologic variables on donor quality of life, we studied long-term data on postoperative psychiatric complications in living liver donors. This study is a focused psychological investigation of diagnoses, treatments, and long-term clinical courses of living liver donors with psychiatric complications. METHODS Of the 142 donors who underwent live-donor liver transplantation at Nagoya University Hospital between April 2004 and July 2014, we investigated those without a history of mental illness who had developed such illness after transplantation and required psychiatric treatment. RESULTS A total of 6 (4.2%) donors developed the following psychiatric complications after transplantation: major depressive disorder (n = 2), panic disorder (n = 2), conversion disorder (n = 1), and substance use disorder (n = 1). Concerning psychiatric treatment, all donors received antianxiety drugs, 3 took antidepressants, and supportive psychiatric therapy was concomitantly provided to all subjects. The average treatment period was 53.3 months. Regarding subject outcomes, 3 donors achieved remission, and the other 3 continued treatment. All subjects showed improvement in Global Assessment of Functioning Scale. CONCLUSION It is important to accurately diagnose postoperative psychiatric complications and provide long-term treatment in close coordination with transplant surgeons.

Abstract
Insulin degludec (IDeg) is a novel basal insulin analogue with an ultralong duration of action that provides flat and stable reductions in blood glucose. The BEGIN ONCE ASIA trial was a phase 3 pan-Asian study examining the efficacy and safety of IDeg once daily (OD) versus insulin glargine (IGlar) OD in insulin-naive patients with type 2 diabetes (T2D). In this multinational, 26-week, open-label, treat-to-target trial, participants were randomised (2:1) to IDeg OD or IGlar OD, administered with one or more antidiabetic drugs (OAD) per os. Here we report the results from a post hoc analysis of Japanese patients enrolled in the trial [n = 133; 63.2 % male; mean age 61.0 years; mean body mass index 24.1 kg/m2; mean glycosylated haemoglobin (HbA1c) 8.5 %]. After 26 weeks, mean HbA1c levels were similar between the two groups [estimated mean treatment difference 0.11 %; 95 % confidence interval (CI) -0.09, 0.31]. Confirmed hypoglycaemia was reported in 53.4 and 61.4 % of patients in the IDeg OD and IGlar OD groups [rate ratio (IDeg/IGlar) 0.87; 95 % CI 0.51, 1.48]. Confirmed nocturnal hypoglycaemia was reported in 17.0 and 22.7 % of patients in the IDeg OD and IGlar OD groups, respectively [rate ratio (IDeg/IGlar) 0.50; 95 % CI 0.19, 1.32]. Adverse event rates were similar between treatment groups. Initiating insulin treatment with IDeg OD in Japanese patients with T2D, inadequately maintained on OADs and requiring treatment intensification, provided effective glycaemic control with low rates of confirmed and nocturnal confirmed hypoglycaemia.

Abstract
Bosonic superweakly interacting massive particles (super-WIMPs) are a candidate for warm dark matter. With the absorption of such a boson by a xenon atom, these dark matter candidates would deposit an energy equivalent to their rest mass in the detector. This is the first direct detection experiment exploring the vector super-WIMPs in the mass range between 40 and 120 keV. With the use of 165.9 day of data, no significant excess above background was observed in the fiducial mass of 41 kg. The present limit for the vector super-WIMPs excludes the possibility that such particles constitute all of dark matter. The absence of a signal also provides the most stringent direct constraint on the coupling constant of pseudoscalar super-WIMPs to electrons. The unprecedented sensitivity was achieved exploiting the low background at a level 10(-4) kg-1 keVee-1 day-1 in the detector.

Abstract
Living donor liver transplantation (LDLT) using a right liver graft with additional vein reconstructions has not been previously reported in a situs inversus (SI) patient. A 60-year-old man with SI was referred for LDLT for end-stage cirrhosis secondary to hepatitis B. The calculated regional volumes of the individual hepatic vein territories in the right liver graft suggested that the middle hepatic vein (MHV) tributaries and the inferior right hepatic veins (IRHVs) should be reconstructed in addition to the right hepatic vein (RHV). On the back-table, the recipient's recanalized umbilical vein graft was anastomosed to the V5 opening, and the other side of vein graft was anastomosed to the RHV and V8 opening to create a large single orifice. After total hepatectomy, the right liver graft was placed in the left subphrenic space at the reversed position. The common orifice of hepatic venous drainage from RHV, V8 and V5 was anastomosed to the anatomical RHV conduit of the recipient, followed by IRHV anastomosis to the inferior vena cava. Postoperative course was almost uneventful, and no vascular complications were experienced. Even for SI patients, LDLT using a right liver graft with reconstructions of the MHV tributaries and the IRHVs is feasible.

Abstract
To clarify the effect of killer cell immunoglobulin-like receptor (KIR) ligand incompatibility on outcomes of acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) patients in complete remission after single cord blood transplantation (CBT), we assessed the outcomes of CBT registered in the Japan Society for Hematopoietic Cell Transplantation (JSHCT) database. A total of 643 acute leukemia (357 AML and 286 ALL) patient and donor pairs were categorized according to their KIR ligand incompatibility by determining whether or not they expressed HLA-C, Bw4 or A3/A11 by DNA typing. A total of 128 patient–donor pairs were KIR ligand-incompatible in the graft-versus-host (GVH) direction and 139 patient–donor pairs were incompatible in the host-versus-graft (HVG) direction. Univariate and multivariate analyses showed no significant differences between the KIR ligand-incompatible and compatible groups in the GVH direction for both AML and ALL patients of overall survival, disease-free survival, relapse incidence, non-relapse mortality and acute GVH disease. However, KIR incompatibility in the HVG direction ameliorated engraftment in ALL patients (hazard ratio 0.66, 95% confidence interval 0.47–0.91, P=0.013). Therefore, there were no effects of KIR ligand incompatibility in the GVH direction on single CBT outcomes for acute leukemia patients without anti-thymocyte globulin use. However, it is necessary to pay attention to KIR incompatibility in the HVG direction for engraftment.

Abstract
We previously analyzed transcriptional regulation of the BMAL1 gene, a critical component of the mammalian clock system and found that the BMAL1 gene is expressed with circadian oscillation and that its regulatory region is located in hypomethylated CpG islands with an open chromatin structure. Here, we found that the BMAL1 gene is not expressed with circadian oscillation in CPT-K cells because the CpG islands located in the BMAL1 promoter are hypermethylated and that 5-aza-2'-deoxycytidine (aza-dC) recovered BMAL1 expression. In contrast, CpG islands in the PER2 promoter were hypomethylated, the PER2 gene was expressed and aza-dC enhanced PER2 gene expression in CPT-K cells. Reporter gene assays showed that intracellular transcriptional machinery for the BMAL1 gene is active, suggesting that BMAL1 inactivation is caused by DNA methylation and not by malfunctional promoter activity. Incubating CPT-K cells with aza-dC also increased CRY1 expression, whereas CLOCK expression was not altered and the CRY1 promoter was unmethylated. These results suggest that aza-dC induces BMAL1 expression via DNA demethylation in the BMAL1 promoter and enhances PER2 and CRY1 transcription. Finally, aza-dC recovered the circadian oscillation of BMAL1 transcription. These results suggest that DNA methylation of the BMAL1 gene is critical for interfering with circadian rhythms.

Abstract
In the patient-specific vascular CFD, determination of the inlet and outlet boundary conditions (BCs) is an important issue for a valid diagnosis. The 3D cine phase-contrast MRI (4D Flow) velocimetry is promising for this issue; yet, its measured velocities contain relatively large error and are not admissible as the BCs without any correction. This paper proposes a novel correction method for determining the BCs accurately using the 4D Flow velocimetry. First, we reveal that the error of the velocity measured by the 4D Flow at each measurement voxel is large but is distributed symmetrically. Secondly, our method pays attention to the incompressibility of the blood and the fact that the volume flow rate (VFR) in each vessel is constant on any cross sections. We reveal that the average of the cross-sectional VFRs integrated from many measurement voxel in each vessel is accurate despite the large error. Finally, we propose the novel correction method, which applies a smoothing to the measured velocities on each inlet or outlet boundary with a low-pass filter and then corrects them with the VFR. The results of the several phantom studies are presented to validate the accuracy of our method. A demonstrative analysis for an actual aneurysm is also presented to show the feasibility and effectiveness of our method.

Abstract
AIMS This phase 3, 26-week, open-label, treat-to-target trial investigated the efficacy and safety of insulin degludec/insulin aspart (IDegAsp) in insulin-naïve Japanese adults with type 2 diabetes. METHODS Subjects were randomized to once-daily injections of IDegAsp (n = 147) or insulin glargine (IGlar) (n = 149), both ±≤2 oral antidiabetic treatments. IDegAsp was given before the largest meal at the discretion of each subject (and maintained throughout the trial); IGlar was dosed according to label. Both insulins were titrated to a target prebreakfast self-measured plasma glucose of 3.9 to <5.0 mmol/l. RESULTS After 26 weeks, mean HbA1c was 7% with IDegAsp and 7.3% with IGlar; superiority of IDegAsp to IGlar was shown (estimated treatment difference, ETD; IDegAsp-IGlar: -0.28% points [-0.46; -0.10](95% CI), p < 0.01). At end-of-trial, mean fasting plasma glucose (FPG) was similar for IDegAsp and IGlar (5.7 vs. 5.6 mmol/l; ETD IDegAsp-IGlar: 0.15 mmol/l [-0.29; 0.60](95% CI), p = NS). IDegAsp was associated with numerically lower rates of overall confirmed (27%) and nocturnal confirmed hypoglycaemia (25%) versus IGlar (estimated rate ratio IDegAsp/IGlar: 0.73 [0.50; 1.08](95% CI), p = NS, and 0.75 [0.34; 1.64](95% CI), p = NS, respectively). Mean daily insulin doses were similar between groups at end-of-trial (both: 0.41 U/kg) as were the increases in body weight from baseline (both: 0.7 kg). Adverse event profiles were similar between groups. CONCLUSIONS IDegAsp provided superior long-term glycaemic control compared to IGlar, with similar FPG and doses and numerically lower rates of overall and nocturnal hypoglycaemia (p = NS).
