Abstract
Uptake of thiosulfate ions as an inorganic sulfur source from the environment is important for bacterial sulfur assimilation. Recently, a selective thiosulfate uptake pathway involving a membrane protein YeeE (TsuA) in Escherichia coli was characterized. YeeE-like proteins are conserved in some bacteria, archaea, and eukaryotes. However, the precise function of YeeE, along with its potential partner protein in the thiosulfate ion uptake pathway, remained unclear. Here, we assessed selective thiosulfate transport via Spirochaeta thermophila YeeE in vitro and characterized E. coli YeeD (TsuB) as an adjacent and essential protein for YeeE-mediated thiosulfate uptake in vivo. We further showed that S. thermophila YeeD possesses thiosulfate decomposition activity and that a conserved cysteine in YeeD was modified to several forms in the presence of thiosulfate. Finally, the crystal structures of S. thermophila YeeE-YeeD fusion proteins at 3.34-Å and 2.60-Å resolutions revealed their interactions. The association was evaluated by a binding assay using purified S. thermophila YeeE and YeeD. Based on these results, a model of the sophisticated uptake of thiosulfate ions by YeeE and YeeD is proposed.

Abstract
Samples of the carbonaceous asteroid Ryugu were brought to Earth by the Hayabusa2 spacecraft. We analyzed 17 Ryugu samples measuring 1 to 8 millimeters. Carbon dioxide-bearing water inclusions are present within a pyrrhotite crystal, indicating that Ryugu's parent asteroid formed in the outer Solar System. The samples contain low abundances of materials that formed at high temperatures, such as chondrules and calcium- and aluminum-rich inclusions. The samples are rich in phyllosilicates and carbonates, which formed through aqueous alteration reactions at low temperature, high pH, and water/rock ratios of <1 (by mass). Less altered fragments contain olivine, pyroxene, amorphous silicates, calcite, and phosphide. Numerical simulations, based on the mineralogical and physical properties of the samples, indicate that Ryugu's parent body formed ~2 million years after the beginning of Solar System formation.

Abstract
The KamLAND-Zen experiment has provided stringent constraints on the neutrinoless double-beta (0νββ) decay half-life in ^{136}Xe using a xenon-loaded liquid scintillator. We report an improved search using an upgraded detector with almost double the amount of xenon and an ultralow radioactivity container, corresponding to an exposure of 970 kg yr of ^{136}Xe. These new data provide valuable insight into backgrounds, especially from cosmic muon spallation of xenon, and have required the use of novel background rejection techniques. We obtain a lower limit for the 0νββ decay half-life of T_{1/2}^{0ν}>2.3×10^{26} yr at 90% C.L., corresponding to upper limits on the effective Majorana neutrino mass of 36-156 meV using commonly adopted nuclear matrix element calculations.

Abstract
Coriandrum sativum L. (coriander), which is an annual herb of the Apiaceae family, has been traditionally used as a remedy. Here we tested whether heated extract of coriander leaf protects nigral dopaminergic neurodegeneration after exposure to 6-hydroxydopamine (6-OHDA). After injection of 6-OHDA into the rat substantia nigra pars compacta (SNpc), dopaminergic degeneration, which was determined by tyrosine hydroxylase immunostaining, was rescued by co-injection of CaEDTA, an extracellular Zn2+ chelator, suggesting that extracellular Zn2+ influx is involved in neurodegeneration. Both intracellular Zn2+ dysregulation determined by ZnAF-2 fluorescence and dopaminergic degeneration in the SNpc induced by 6-OHDA were rescued by co-injection of 0.25% coriander extract, which also reduced reactive oxygen species (ROS) production in the SNpc determined by aminophenyl fluorescein fluorescence. The present study suggests that coriander leaf extract protects nigral dopaminergic neurodegeneration induced by intracellular Zn2+ dysregulation. It is likely that the nutraceutical property of coriander leaf extract contributes to the protection via reducing ROS production.

Abstract
To elucidate the mechanism and significance of 6-hydroxydopamine (6-OHDA)-induced Zn2+ toxicity, which is involved in neurodegeneration in the substantia nigra pars compacta (SNpc) of rats, we postulated that intracellular hydrogen peroxide (H2O2) produced by 6-OHDA is a trigger for intracellular Zn2+ dysregulation in the SNpc. Intracellular H2O2 level elevated by 6-OHDA in the SNpc was completely inhibited by co-injection of GBR 13069 dihydrochloride (GBR), a dopamine reuptake inhibitor, suggesting that 6-OHDA taken up through dopamine transporters produces H2O2 in the intercellular compartment of dopaminergic neurons. When the SNpc was perfused with H2O2, glutamate accumulated in the extracellular compartment and the accumulation was inhibited in the presence of N-(p-amylcinnamoyl)anthranilic acid (ACA), a blocker of the transient receptor potential melastatin 2 (TRPM2) channels. In addition to 6-OHDA, H2O2 also induced intracellular Zn2+ dysregulation via AMPA receptor activation followed by nigral dopaminergic degeneration. Furthermore, 6-OHDA-induced nigral dopaminergic degeneration was completely inhibited by co-injection of either HYDROP, an intracellular H2O2 scavenger or GBR into the SNpc. The present study indicates that H2O2 is produced by 6-OHDA taken up through dopamine transporters in the SNpc, is retrogradely transported to presynaptic glutamatergic terminals, activates TRPM2 channels, accumulates glutamate in the extracellular compartment, and induces intracellular Zn2+ dysregulation via AMPA receptor activation, resulting in nigral dopaminergic degeneration prior to movement disorder. It is likely that intracellular H2O2, but not extracellular H2O2, is a key trigger for nigral dopaminergic degeneration via intracellular Zn2+ dysregulation.

Abstract
This study investigated the utility of patent ductus arteriosus (PDA) closure with hemostatic clip by comparing with traditional PDA closure. Medical records of 51 dogs with surgical closure of PDA were reviewed and retrospective study was conducted. 29 dogs were treated by procedure with hemostatic clip (Group HC), and 22 dogs were treated by surgical ligation (Group SL). Data pertaining to breed, sex, age and body weight at the time of surgery, echocardiographic minimal ductal diameter, duration of surgery, hemostatic clip size, echocardiographic findings, hemor-rhage, residual ductal flow and recanalization were collected from records. The results showed that procedure with hemostatic clip had been selected in lighter dogs than traditional PDA closure. Duration of surgery performed only hemostatic clip technique was significantly shorter than that in group SL. Preoperative LVIDd, E-wave and FS were significantly lower than postoperative ones. As regard all parameters, the differences between pre- and postoperative periods were not significantly different between group HC and group SL. Hemorrhage, residual ductal flow, and recanalization were not significantly different in both groups. The present study showed that procedure with hemostatic clip is beneficial in that it is available in smaller dogs and can make shorter operation duration than traditional PDA closure. Moreover, the procedure is effective for the resolution of volume overload of the left atrium and ventricle in short-term outcome. Complications including hemorrhage, residual ductal flow and recanaliza-tion were not significantly different with both techniques.

Abstract
On the basis of the evidence that extracellular Zn2+ influx induced with AMPA causes Parkinson's syndrome in rats that apomorphine-induced movement disorder emerges, here we used a low dose of AMPA, which does not increase intracellular Zn2+ level in the substantia nigra pars compacta (SNpc) of young adult rats, and tested whether intracellular Zn2+ dysregulation induced with AMPA is accelerated in the SNpc of aged rats, resulting in age-related vulnerability to Parkinson's syndrome. When AMPA (1 mM) was injected at the rate of 0.05 μl/min for 20 min into the SNpc, intracellular Zn2+ level was increased in the SNpc of aged rats followed by increase in turning behavior in response to apomorphine and nigral dopaminergic degeneration. In contrast, young adult rats do not show movement disorder and nigral dopaminergic degeneration, in addition to no increase in intracellular Zn2+. In aged rats, movement disorder and nigral dopaminergic degeneration were rescued by co-injection of either extracellular (CaEDTA) or intracellular (ZnAF-2DA) Zn2+ chelators. 1-Naphthyl acetyl spermine (NASPM), a selective blocker of Ca2+- and Zn2+-permeable GluR2-lacking AMPA receptors blocked increase in intracellular Zn2+ in the SNpc of aged rats followed by rescuing nigral dopaminergic degeneration. The present study indicates that intracellular Zn2+ dysregulation is accelerated by Ca2+- and Zn2+-permeable GluR2-lacking AMPA receptor activation in the SNpc of aged rats, resulting in age-related vulnerability to Parkinson's syndrome.

Abstract
BACKGROUND Although immunotherapy is thought to be a promising cancer treatment, most patients do not respond to immunotherapy. In this post hoc analysis of a phase 1/2 study, associations of programmed death ligand 1 (PD-L1), PD-L2, and HLA class I expressions with responses to dendritic cells (DCs)-based immunotherapy were investigated in patients with advanced sarcoma. METHODS This study enrolled 35 patients with metastatic and/or recurrent sarcomas who underwent DC-based immunotherapy. The associations of PD-L1, PD-L2, and HLA class I expressions in tumor specimens, which were resected before immunotherapy, with immune responses (increases of IFN-γ and IL-12) and oncological outcomes were evaluated. RESULTS Patients who were PD-L2 (+) showed lower increases of IFN-γ and IL-12 after DC-based immunotherapy than patients who were PD-L2 (-). The disease control (partial response or stable disease) rates of patients who were PD-L1 (+) and PD-L1 (-) were 0% and 22%, respectively. Disease control rates of patients who were PD-L2 (+) and PD-L2 (-) were 13% and 22%, respectively. Patients who were PD-L1 (+) tumors had significantly poorer overall survival compared with patients who were PD-L1 (-). No associations of HLA class I expression with the immune response or oncological outcomes were observed. CONCLUSIONS This study suggests that PD-L1 and PD-L2 are promising biomarkers of DC-based immunotherapy, and that addition of immune checkpoint inhibitors to DC-based immunotherapy may improve the outcomes of DC-based immunotherapy.

Abstract
We have demonstrated that a bacterial membrane protein, YeeE, mediates thiosulfate uptake. Thiosulfate is used for cysteine synthesis in bacteria as an inorganic sulfur source in the global biological sulfur cycle. The crystal structure of YeeE at 2.5-Å resolution reveals an unprecedented hourglass-like architecture with thiosulfate in the positively charged outer concave side. YeeE is composed of loops and 13 helices including 9 transmembrane α helices, most of which show an intramolecular pseudo 222 symmetry. Four characteristic loops are buried toward the center of YeeE and form its central region surrounded by the nine helices. Additional electron density maps and successive molecular dynamics simulations imply that thiosulfate can remain temporally at several positions in the proposed pathway. We propose a plausible mechanism of thiosulfate uptake via three important conserved cysteine residues of the loops along the pathway.

Abstract
BACKGROUND Localized-type tenosynovial giant cell tumor (TGCT) is a rare, neoplastic disease with only limited data supporting treatment protocols. We describe treatment protocols and evaluate their oncological outcome, complications, and functional results in a large multicenter cohort of patients. A secondary study aim was to identify factors associated with local recurrence after surgical treatment. METHODS Patients with histologically proven localized TGCT of a large joint were included if they had been treated between 1990 and 2017 in 1 of 31 tertiary sarcoma centers. Of 941 patients with localized TGCT, 62% were female. The median age at initial treatment was 39 years, and the median duration of follow-up was 34 months. Sixty-seven percent of the tumors affected the knee, and the primary treatment at the tertiary center was 1-stage open resection in 73% of the patients. Proposed factors for predicting a first local recurrence after treatment in the tertiary center were tested in a univariate analysis, and those that demonstrated significance were subsequently included in a multivariate analysis. RESULTS The localized TGCT recurred in 12% of all cases, with local-recurrence-free rates at 3, 5, and 10 years of 88%, 83%, and 79%, respectively. The strongest factor for predicting recurrent disease was a prior recurrence (p < 0.001). Surgical treatment decreased pain and swelling in 71% and 85% of the patients, respectively, and such treatment was associated with complications in 4% of the patients. Univariate and multivariate analyses of the patients who had not undergone therapy previously yielded positive associations between local recurrence and a tumor size of ≥5 cm versus <5 cm (hazard ratio [HR] = 2.50; 95% confidence interval [CI] = 1.32 to 4.74; p = 0.005). Arthroscopy (versus open surgery) was significantly associated with tumor recurrence in the univariate analysis (p = 0.04) but not in the multivariate analysis (p = 0.056). CONCLUSIONS Factors associated with recurrence after resection of localized-type TGCT were larger tumor size and initial treatment with arthroscopy. Relatively low complication rates and good functional outcomes warrant an open approach with complete resection when possible to reduce recurrence rates in high-risk patients. LEVEL OF EVIDENCE Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Abstract
Coriandrum sativum (coriander) is an annual herb of the Apiaceae family and has been used as a traditional remedy. Here we examined whether heated leaf extract of coriander decreases the concentrations of heavy metals in tissues. Male ddY mice were given a drinking water containing 0.25% of heated leaf extract of coriander for 8 weeks. Eight weeks after the intake, the concentrations of zinc, iron, copper, arsenic, and cadmium were measured in the liver and kidney. The intake of coriander did not modify the concentrations of all heavy metals tested in the liver, but decreased the concentrations of iron, arsenic, and cadmium in the kidney. Because heavy metals can induce oxidative stress, the effect of coriander intake on hydrogen peroxide-induced oxidative stress was compared between slices from the kidney and liver. The slices were immersed in Ringer solution containing 100 μM hydrogen peroxide and aminophenyl fluorescein (APF), a probe for detecting reactive oxygen species (ROS). APF fluorescence was markedly increased in the control kidney slices, while the increase was completely blocked in kidney slices from coriander intake group. In contrast, APF fluorescence was also markedly increased in the control liver slices, while the increase was not blocked by coriander intake. The present study indicates that intake of coriander leaf extract contributes to powerful resistance to oxidative stress in the kidney, probably via decreased concentrations in heavy metals. It is likely that decrease in arsenic concentration to the detection limit is a major factor for the resistance.

Abstract
We present a precision analysis of the ^{136}Xe two-neutrino ββ electron spectrum above 0.8 MeV, based on high-statistics data obtained with the KamLAND-Zen experiment. An improved formalism for the two-neutrino ββ rate allows us to measure the ratio of the leading and subleading 2νββ nuclear matrix elements (NMEs), ξ_{31}^{2ν}=-0.26_{-0.25}^{+0.31}. Theoretical predictions from the nuclear shell model and the majority of the quasiparticle random-phase approximation (QRPA) calculations are consistent with the experimental limit. However, part of the ξ_{31}^{2ν} range allowed by the QRPA is excluded by the present measurement at the 90% confidence level. Our analysis reveals that predicted ξ_{31}^{2ν} values are sensitive to the quenching of NMEs and the competing contributions from low- and high-energy states in the intermediate nucleus. Because these aspects are also at play in neutrinoless ββ decay, ξ_{31}^{2ν} provides new insights toward reliable neutrinoless ββ NMEs.

Abstract
The herbicide paraquat (PQ) has been reported to enhance the risk of developing Parkinson's disease (PD) from epidemiological studies. PQ-induced reactive oxygen species (ROS) are linked with a selective loss of nigrostriatal dopaminergic neurons. Here, we first report a unique mechanism of nigrostriatal dopaminergic degeneration, in which rapid intracellular Zn2+ dysregulation via PQ-induced ROS production causes PD in rats. When the substantia nigra pars compacta (SNpc) of rats was perfused with PQ, extracellular concentrations of glutamate and Zn2+ were increased and decreased, respectively, in the SNpc. These changes were ameliorated by co-perfusion with Trolox, an antioxidative agent. In in vitro slice experiments, PQ rapidly increased extracellular Zn2+ influx via AMPA receptor activation. Both loss of nigrostriatal dopaminergic neurons and increase in turning behavior in response to apomorphine were markedly reduced by coinjection of PQ and intracellular Zn2+ chelator, i.e., ZnAF-2DA into the SNpc. Furthermore, loss of nigrostriatal dopaminergic neurons induced with a low dose of PQ, which did not induce any behavioral abnormality, was completely blocked by coinjection of ZnAF-2DA. The present study indicates that rapid influx of extracellular Zn2+ into dopaminergic neurons via AMPA receptor activation, which is initially induced by PQ-mediated ROS production in the SNpc, induces nigrostriatal dopaminergic degeneration, resulting in PQ-induced PD in rats. Intracellular Zn2+ dysregulation in dopaminergic neurons is the cause of PQ-induced pathogenesis in the SNpc, and the block of intracellular Zn2+ toxicity leads to defending PQ-induced pathogenesis.

Abstract
Aims The aims of this study were to evaluate the long-term outcome of surgery for bone or soft-tissue metastases from renal cell carcinoma (RCC) and to determine factors that affect prognosis. Patients and Methods Between 1993 and 2014, 58 patients underwent surgery for bone or soft-tissue metastases from RCC at our hospital. There were 46 men and 12 women with a mean age of 60 years (25 to 84). The mean follow-up period was 52 months (1 to 257). The surgical sites included the spine (33 patients), appendicular skeleton (ten patients), pelvis (eight patients), thorax (four patients), and soft tissue (three patients). The surgical procedures were en bloc metastasectomy in 46 patients (including 33 patients of total en bloc spondylectomy (TES)) and intralesional curettage in 12 patients. These patients were retrospectively evaluated for factors associated with prognosis. Results The one-, three-, five-, ten-, and 15-year overall survival (OS) rates were 89%, 75%, 62%, 48%, and 25%, respectively. The median survival time (MST) was 127 months for en bloc metastasectomy and 54 months for intralesional curettage and bone grafting. The median survival time was 127 months for the spine, 140 months for lesions of the appendicular skeleton, and 54 months for the pelvis. Multivariate analysis showed that non-clear cell type RCC and metastases to more than two sites were independent risk factors for a poor prognosis. Conclusion Patients with bone or soft-tissue metastases from a RCC have a reasonable prognosis, making surgical resection a viable option even in patients in whom the metastases are advanced.

Abstract
On the basis of the findings that the rapid influx of extracellular Zn2+ into nigral dopaminergic neurons causes dopaminergic neurodegeneration, here we report that AMPA causes movement disorder in rats. AMPA markedly increased turning behavior in response to apomorphine 1 and 2 weeks after AMPA injection into the substantia nigra pars compacta (SNpc), while AMPA-induced movement disorder was suppressed by co-injection of intracellular Zn2+ chelators, i.e., ZnAF-2DA and TPEN, suggesting that AMPA-induced movement disorder is due to intracellular Zn2+ dysregulation. Furthermore, AMPA markedly induced loss of nigrostriatal dopaminergic neurons 2 weeks after AMPA injection into the SNpc, while AMPA-induced neurodegeneration was also suppressed in the SNpc and the striatum by co-injection of ZnAF-2DA and TPEN. AMPA rapidly increased nigral intracellular Zn2+ after AMPA injection into the SNpc and this increase was blocked by co-injection of TPEN. These results indicate that AMPA receptor activation rapidly increases influx of extracellular Zn2+ into nigral dopaminergic neurons and causes nigrostriatal dopaminergic neurodegeneration, resulting in movement disorder in rats. The evidence that AMPA-induced intracellular Zn2+ dysregulation causes movement disorder via nigrostriatal dopaminergic neurodegeneration suggests that AMPA receptors, probably Ca2+- and Zn2+-permeable GluR2-lacking AMPA receptors are potential targets for overcoming Parkinson's syndrome.

Abstract
Azathioprine (AZA) is increasingly being prescribed to rheumatoid arthritis (RA) patients. Following oral administration, AZA is converted into its active form. Inflammatory bowel disease (IBD) and systemic lupus erythematosus (SLE) patients with low thiopurine (S)-methyltransferase (TPMT) activity tend to respond well to AZA therapy. In a previous study of Japanese SLE patients under low-dose AZA therapy, the group with the 94C>A mutation in inosine triphosphatase (ITPA) showed greater improvement in their disease activity index. However, it is not yet clear how genotypes relate to responsiveness to RA treatment. The genotypes ITPA 94C>A, TPMT*3C, NUDT15 595C>T, GST-M1, GST-T1 and MRP4/ABCC4 2269G>A of Japanese patients with RA were determined. The relationship between these genotypes and response to AZA therapy was evaluated using the Disease Activity Score 28 (DAS28) and various medical data. Of the 22 patients 15 had the ITPA 94C/C genotype, 7 had the ITPA 94C/A genotype, none had the TPMT*3C mutation, 4 had the NUDT15 595C>T mutation, 8 had the GST-M1 and T1 null genotypes and 9 had the MRP4/ABCC4 2269G>A mutation. Changes in DAS28 at 6 months after baseline were similar in both ITPA genotype groups. However, the maintenance dose of AZA was significantly lower in the C/A group than in the C/C group (0.85±0.30 mg/kg/day vs. 1.2±0.46 mg/kg/day, respectively; p = 0.043). The ITPA 94C/A group showed the same response to RA treatment as the C/C group, but at a lower dose. This demonstrates that RA patients with the ITPA 94C>A mutation are more responsive to AZA.

Abstract
We propose a differential interference contrast method for cells using hard x-ray Gabor holography and knife-edge filtering in the spatial frequency domain, without relying on beam shearing. A phase object is holographically recorded and reconstructed by computer. Interference between the wavefronts of zeroth order weighted by ejπ/2 in the positive frequency region produces a dark image. Similarly, interference between the wavefronts of the zeroth order weighted by ej3π/2 in the negative frequency region produces a bright image. By adding these two intensity distributions, good quality phase-contrast images of 8-μm-diameter polystyrene beads and human HeLa cells were obtained.

Abstract
Abstract:A problem of identifying the phase response curve of the myocardial pacemaker was investigated using a simple dynamic system model of cardiac arrhythmia. A hybrid optimization method of a genetic algorithm and a local optimization technique was employed to obtain a solution of the model fitting. The method was applied to two categories of arrhythmias, ventricular parasystole and high-degree AV block. The present study offered a new insight into the mechanism of cardiac arrhythmias.

Abstract
Summary
Objectives: The aim of the study was to develop a low-cost and compact system for analysis of tremor using a three-axis accelerometer (the Wii Remote (Nintendo)). To analyze tremor, we hypothesized that the influence of gravitational acceleration should be separated from that of movement. This hypothesis was tested experimentally and we also attempted to record and analyze tremor using our system in a clinical ward.
Methods: A system for tremor measurement and analysis was developed using the three-axis accelerometer built into the Wii Remote. The frequency and amplitude of mechanical oscillation were calculated using methods for frequency analysis of the axis of largest variance and an estimation of tremor amplitude.
Results: The system consists of a program for measurement and analysis of Wii Remote acceleration (Tremor Analyzer), a Wii Remote, a Bluetooth USB adapter and a Web camera. The Tremor Analyzer has a GUI (graphical user interface) that is divided into five segments. The sampling period of the analyzer is 30 msec. To confirm the hypothesis, mechanical oscillations were fed to the Wii Remote. The peak frequency of the power spectrum and the frequency of the oscillation generator were in good agreement, except at 1 Hz (0.01 G) and 2 Hz (0.02 G). With a change in the sum of squares of the three axes from 1.0 to 1.8 (G), the estimated and generated amplitude (0.3 cm) were in close agreement.
Conclusions: This system using a Wii Remote is capable of analyzing frequency and estimated amplitude of tremor between 3 Hz and 15 Hz.

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
In this experiment, we examined a possible protective effect of encapsulated neurotrophic factor-secreting cell grafting for ischemic injury. We established a basic fibroblast growth factor (bFGF)-secreting cell line by genetic manipulation. We enveloped these cells into polymer capsules, which consist of a semipermeable membrane, and implanted them into the right striatum of rats. At 6 days after implantation, these rats received right middle cerebral artery occlusion (MCAO) using interluminal suture technique. At 24 h after MCAO, rats were sacrificed and their cerebral infarction volume was determined by 2,3,5-triphenyltetrazolium chloride (TTC) staining and image analysis. We found approximately 30% reduction in infarct volume in the encapsulated bFGF-secreting cell grafting groups vs. the encapsulated naive BHK cell grafting group or the without implantation group. We measured bFGF secretion from encapsulated bFGF-secreting cells using enzyme-linked immunosorbent assay (ELISA). The retrieved capsules continued to secrete bFGF. There was no significant difference of bFGF secretion between the capsules before and after transplantation. A large number of viable BHK-bFGF cells was observed within the full length of the retrieved capsule. These results indicate that encapsulated bFGF-secreting cell grafting exerts a protective effect on ischemic injury.

Abstract
Abstract
Background
Atrial fibrillation is common after oesophageal surgery. The aim of this study was to evaluate whether landiolol hydrochloride was effective and safe in the prevention of atrial fibrillation after oesophagectomy, and to see whether a reduction in incidence of atrial fibrillation would reduce other postoperative complications.
Methods
This single-centre study enrolled patients scheduled for transthoracic oesophagectomy in a randomized, double-blind, placebo-controlled trial between March 2013 and January 2016. Enrolled patients were randomized with a 1 : 1 parallel allocation ratio to either landiolol prophylaxis or placebo. The primary endpoint was the occurrence of atrial fibrillation after oesophagectomy. Secondary endpoints were incidence of postoperative complications, and effects on haemodynamic and inflammatory indices.
Results
One hundred patients were enrolled, 50 in each group. Postoperative atrial fibrillation occurred in 15 patients (30 per cent) receiving placebo versus five (10 per cent) receiving landiolol (P = 0·012). The overall incidence of postoperative complications was significantly lower in the landiolol group (P = 0·046). In the landiolol group, postoperative heart rate was suppressed effectively, but the decrease in BP was not harmful. The interleukin 6 level was significantly lower on days 3 and 5 after surgery in the landiolol group (P = 0·001 and P = 0·002 respectively).
Conclusion
Landiolol was effective and safe in preventing atrial fibrillation after oesophagectomy. Registration number: UMIN000010648 (http://www.umin.ac.jp/ctr/).

Abstract
BACKGROUND Antimelanoma differentiation-associated protein (anti-MDA)5 antibodies are associated with rapidly progressive interstitial lung disease (RP-ILD) in patients with clinically amyopathic dermatomyositis (CADM) or dermatomyositis (DM). OBJECTIVES We aimed to evaluate the relevance of monitoring anti-MDA5 antibody levels for the management of RP-ILD in patients with CADM or DM. METHODS Twelve patients with CADM (n = 10) or DM (n = 2) accompanied by RP-ILD were included. Baseline characteristics and outcomes were recorded. Serial measurements of anti-MDA5 antibody levels were measured. All patients were treated with corticosteroids, tacrolimus and intravenous cyclophosphamide. RESULTS All patients achieved RP-ILD remission after combined immunosuppressive therapy for a mean of 6·8 months, with significant decreases noted in the mean anti-MDA5 antibody levels at remission. Six (50%) patients became anti-MDA5 antibody negative after therapy. After a mean follow-up of 31 months, RP-ILD relapse was observed in four (33%) patients in both the anti-MDA5 antibody sustained positive group and the negative conversion group. However, relapsed patients in the sustained positive group relapsed earlier than those in the negative conversion group. Thus, a decrease in anti-MDA5 antibody levels during remission was associated with longer remission. Relapses were associated with a reincrease of anti-MDA5 antibody levels in four of four (100%) patients. In contrast, none of the patients without reincrease in anti-MDA5 antibody exhibited symptoms of relapse during follow-up. Therefore, reincrease in anti-MDA5 antibody levels was associated with relapse. CONCLUSIONS The anti-MDA5 antibody level is a novel parameter for monitoring and a good predictor of RP-ILD relapse in patients with CADM or DM.

Abstract
Light and electron microscopy showed gastric spirilla in the gastric mucosa of 45 clinically normal rhesus monkeys (Macaca mulatta). In paraffin sections, gastric spirilla were best shown by silver impregnation stains. When stained by hematoxylin and eosin (HE), gastric spirilla may be mistaken for strands of mucus. In thick sections of epon-embedded tissue, gastric spirilla looked like “corkscrews” with up to 12 coils. They were 8 μm long and 0.7 μm wide, and had characteristic bipolar flagella. They were concentrated in the gastric glands at the isthmus, were less common at the neck and base, and were absent in the gastric lumen. Gastric spirilla were associated closely with parietal cells and could penetrate their cytoplasm. Gastric spirilla elicit neither changes of host cytocomponents nor an inflammatory response in the gastric mucosa.

Abstract
Rhesus monkeys (Macaca mulatta), given 3 × 108 to 5 × 1010Shigella flexneri 2a orally, developed signs of acute shigellosis within 24 hours. A diffuse acute colitis was well established at 48 hours. The inflammatory reaction was confined to the mucosa. The submucosa showed only edema. The shigellae were found predominantly in the columnar cells of the surface epithelium, less frequently in those of the crypt, and least frequently in the lamina propria. Shigella bacilli invaded the columnar cells from the intestinal lumen. The bacilli multiplied within epithelial cells and spread laterally to adjacent epithelial cells and penetrated the lamina propria. The bacterial invasion affected epithelial cells unevenly and resulted in the disappearance of goblet cells and pyknotic shrinkage of the surface epithelial cells. Epithelial cells had abnormal and accelerated exfoliation which resulted in multifocal epithelial defects. There was a distinct correlation between the quantity of bacilli present in tissues and the intensity of the inflammatory response. The small intestines were spared.

Abstract
Intestinal spirochetosis, an infection of the mucosa by spiral-shaped organisms, was studied in clinically normal rhesus monkeys (Macaca mulatta) by histology, transmission and scanning electron microscopy. The incidence of intestinal spirochetosis was 42% in 221 monkeys. Spiral organisms stained with hematoxylin and eosin (HE) appeared as a broad basophilic haze on the colonic surface and were strongly positive by the Warthin-Starry stain. Spiral-shaped bacteria include two structurally different organisms: spirochetes and flagellated microbes. They intimately populated the brush border of the surface of the epithelium of the large intestine. They were absent in the crypts and in the small intestine. Infection by spirochetes produced no alteration of cytocomponents of the underlying host structures. Spirochetes and flagellates infrequently penetrated beyond the brush border into the epithelial cytoplasm and also into the lamina propria. Even in cases where invasion was documented, no inflammatory response was found.

Abstract
The aim of this study was to explore the biological functions of a tetraspanin family protein CD82 expressed aberrantly in chemotherapy-resistant CD34(+)/CD38(-) acute myelogenous leukemia (AML) cells. Microarray analysis of patient-isolated CD34(+)/CD38(-) AML cells revealed that the levels of anti-apoptotic protein BCL2L12 were downregulated after CD82 depletion by specific short hairpin RNA (shRNA). Western blot analysis indicated that BCL2L12 was aberrantly expressed in patient-isolated AML cells and AML cell lines. Furthermore, CD82 blockade by a specific antibody downregulated BCL2L12 in parallel with dephosphorylation of signal transducer and activator of transcription 5 (STAT5) and AKT, whereas pharmacological inhibition of STAT5 and AKT activation decreased BCL2L12 expression in leukemia cells. In addition, shRNA-mediated downregulation of BCL2L12 increased the levels of cleaved caspase-3 and suppressed proliferation of leukemia cells, impairing their engraftment in immunodeficient mice. Taken together, our results indicate that CD82 regulated BCL2L12 expression via STAT5A and AKT signaling and stimulated proliferation and engrafting of leukemia cells, suggesting that CD82 and BCL2L12 may be promising therapeutic targets in AML.

Abstract
Analyses of nuclear emulsion detectors that can detect and identify charged particles or radiation as tracks have typically utilized optical microscope systems because the targets have lengths from several μm to more than 1000 μm. For recent new nuclear emulsion detectors that can detect tracks of submicron length or less, the current readout systems are insufficient due to their poor resolution. In this study, we developed a new system and method using an optical microscope system for rough candidate selection and the hard X-ray microscope system at SPring-8 for high-precision analysis with a resolution of better than 70 nm resolution. Furthermore, we demonstrated the analysis of submicron-length tracks with a matching efficiency of more than 99% and position accuracy of better than 5 μm. This system is now running semi-automatically.

Abstract
A novel vitamin D3 analogue, [2 beta-(3-hydroxypropoxy)-calcitriol: ED-71] showed a similar Ca-regulating activity as calcitriol in the in vivo and in vitro Ca mobilization test and ex vivo intestinal Ca absorption assay using vitamin D-deficient rats. The differentiation-inducing activity of ED-71 in mouse myeloid leukemia cell line (WEHI-3 cell) was slightly less than that of calcitriol. ED-71 distributes predominantly in plasma as an intact form and its half-life plasma was twice as long as that of calcitriol. Further study revealed that the higher binding potency of ED-71 to plasma-specific vitamin D-binding protein (DBP) compared with that of calcitriol accounts for its stability in the blood circulation. The pharmacological effect of ED-71 for the animal models with osteoporosis seemed to be better than that calcitriol. These results suggest that ED-71 should become a valuable therapeutic long-acting drug for patients with osteoporosis.

Abstract
The binding potencies of OCT to chick intestinal calcitriol receptor and vitamin DBP were approximately 1/8 and 1/600 of the respective values of calcitriol. OCT is circulating mainly as an intact form bound to chylomicrons and/or lipoproteins. Intravenously injected [3H]-OCT to normal rats was quickly decreased from blood and rapid excretion of OCT as a glucuronate into bile was observed. However, significant amounts of radioactivities were recovered in the intact form in liver and intestine even after 24 h. The separation of calcemic and immune and/or differentiation activities may be derived from the rapid turnover and the nonspecific transporting system.

Abstract
In 1999, we developed a technique for biological reconstruction after excision of a bone tumour, which involved using autografts of the bone containing the tumour treated with liquid nitrogen. We have previously reported the use of this technique in 28 patients at a mean follow up of 27 months (10 to 54). In this study, we included 72 patients who underwent reconstruction using this technique. A total of 33 patients died and three were lost to follow-up, at a mean of 23 months (2 to 56) post-operatively, leaving 36 patients available for a assessment at a mean of 101 months 16 to 163) post-operatively. The methods of reconstruction included an osteo-articular graft in 16, an intercalary in 13 and, a composite graft with prosthesis in seven. Post-operative function was excellent in 26 patients (72.2%), good in seven (19.4%), and fair in three (8.3%) according to the functional evaluation system of Enneking. No recurrent tumour occurred within the grafts. The autografts survived in 29 patients (80.6%), and the rates of survival at five and ten years were 86.1% and 80.6 %, respectively. Seven of 16 osteo-articular grafts (44%) failed because of fracture or infection, but all the composite and intercalary grafts survived. The long-term outcomes of frozen autografting, particularly using composite and intercalary grafts, are satisfactory and thus represent a good method of treatment for patients with a sarcoma of bone or soft tissue.

Abstract
There have been a few reports of patients with a combination of lumbar and thoracic spinal stenosis. We describe six patients who suffered unexpected acute neurological deterioration at a mean of 7.8 days (6 to 10) after lumbar decompressive surgery. Five had progressive weakness and one had recurrent pain in the lower limbs. There was incomplete recovery following subsequent thoracic decompressive surgery. The neurological presentation can be confusing. Patients with compressive myelopathy due to lower thoracic lesions, especially epiconus lesions (T10 to T12/L1 disc level), present with similar symptoms to those with lumbar radiculopathy or cauda equina lesions. Despite the rarity of this condition we advise that patients who undergo lumbar decompressive surgery for stenosis should have sagittal whole spine MRI studies pre-operatively to exclude proximal neurological compression.
