Abstract
Background: The advancement of multidisciplinary treatment has increased the need to develop tests to monitor tumor burden during treatment. We herein analyzed urinary microRNAs within extracellular vesicles from patients with esophageal squamous cell carcinoma (ESCC) and normal individuals using a microarray. Methods: Patients with advanced ESCC who underwent esophagectomy (A), endoscopic submucosal resection (ESD) (B), and healthy donors (C) were included. Based on microRNA expression among the groups (Analysis 1), microRNAs with significant differences between groups A and C were selected (Analysis 2). Of these candidates, microRNAs in which the change between A and C was consistent with the change between B and C were selected for downstream analysis (Analysis 3). Finally, microRNA expression was validated in patients with recurrence from A (exploratory analysis). Results: For analysis 1, 205 microRNAs were selected. For Analyses 2 and 3, the changes in 18 microRNAs were consistent with changes in tumor burden as determined by clinical imaging and pathological findings. The AUC for the detection of ESCC using 18 microRNAs was 0.72. In exploratory analysis, three of eighteen microRNAs exhibited a concordant trend with recurrence. Conclusions: The current study identified the urinary microRNAs which were significantly expressed in ESCC patients. Validation study is warranted to evaluate whether these microRNAs could reflect tumor burden during multidisciplinary treatment for ESCC.

Abstract
To detect and track structural changes in atomic nuclei, the systematic study of nuclear levels with firm spin-parity assignments is important. While linear polarization measurements have been applied to determine the electromagnetic character of gamma-ray transitions, the applicable range is strongly limited due to the low efficiency of the detection system. The multi-layer Cadmium-Telluride (CdTe) Compton camera can be a state-of-the-art gamma-ray polarimeter for nuclear spectroscopy with the high position sensitivity and the detection efficiency. We demonstrated the capability to operate this detector as a reliable gamma-ray polarimeter by using polarized 847-keV gamma rays produced by the [Formula: see text]([Formula: see text]) reaction. By combining the experimental data and simulated calculations, the modulation curve for the gamma ray was successfully obtained. A remarkably high polarization sensitivity was achieved, compatible with a reasonable detection efficiency. Based on the obtained results, a possible future gamma-ray polarimetery is discussed.

Abstract
Microbial rhodopsins are light-receptive proteins with various functions triggered by the photoisomerization of the retinal chromophore from the all-trans to 13-cis configuration. A retinal chromophore is covalently bound to a lysine residue in the middle of the seventh transmembrane helix via a protonated Schiff base. Bacteriorhodopsin (BR) variants lacking a covalent bond between the side chain of Lys-216 and the main chain formed purple pigments and exhibited a proton-pumping function. Therefore, the covalent bond linking the lysine residue and the protein backbone is not considered a prerequisite for microbial rhodopsin function. To further examine this hypothesis regarding the role of the covalent bond at the lysine side chain for rhodopsin functions, we investigated K255G and K255A variants of sodium-pumping rhodopsin, Krokinobacter rhodopsin 2 (KR2), with an alkylamine retinal Schiff base (prepared by mixing ethyl- or n-propylamine and retinal (EtSB or nPrSB)). The KR2 K255G variant incorporated nPrSB and EtSB as similarly to the BR variants, whereas the K255A variant did not incorporate these alkylamine Schiff bases. The absorption maximum of K255G + nPrSB was 524-516 nm, which was close to the 526 nm absorption maximum of the wild-type + all-trans retinal (ATR). However, the K255G + nPrSB did not exhibit any ion transport activity. Since the KR2 K255G variant easily released nPrSB during light illumination and did not form an O intermediate, we concluded that a covalent bond at Lys-255 is important for the stable binding of the retinal chromophore and formation of an O intermediate to achieve light-driven Na+ pump function in KR2.

Abstract
OBJECTIVE To investigate the criteria, based on fetal TR waveforms in late gestation, to predict biventricular circulation (BV) after birth in cases of tricuspid valve dysplasia (TVD) or Ebstein's anomaly diagnosed during the fetal period. METHODS We included 35 consecutive cases diagnosed with TVD or Ebstein's anomaly during the fetal period between January 2008 and December 2021 at Kanagawa Children's Medical Center, Kanagawa, Japan. The maximum velocity and change in pressure over time of tricuspid regurgitation (TR) jet (dP/dt), estimated using TR waveforms obtained during the late-gestation period (gestational age ≥ 28 weeks), were collected from patient records. dP/dt was calculated by dividing the change in estimated right ventricular pressure obtained using Bernoulli's principle by the time taken for the TR maximum velocity to change from one-third to two-thirds of its peak value. The outcome was divided into four categories: BV, single ventricular circulation, neonatal death and fetal death. Patients with BV were included in the BV group, while patients with single ventricular circulation, neonatal death or fetal death were included in the non-BV (NBV) group. RESULTS Overall, 19 and 16 patients were included in the BV and NBV groups, respectively. The median TR maximum velocity was 3.3 (range, 2.4-3.6) m/s in the BV group and 1.9 (range, 1.0-3.3) m/s in the NBV group. There were no cases of postnatal BV in fetuses with TR maximum velocity < 2.4 m/s; cases with TR maximum velocity of 2.4-3.3 m/s were observed in both BV and NBV groups. Receiver-operating-characteristics-curve analysis was performed on the 11 patients in the BV group and five patients in the NBV group with a TR maximum velocity of 2.4-3.3 m/s. dP/dt ≥ 350 mmHg/s and TR maximum velocity ≥ 2.9 m/s were identified as criteria for predicting the outcome in such cases. The performance of dP/dt ≥ 350 mmHg/s in predicting BV after birth in fetuses with TVD or Ebstein's anomaly was higher compared to that of TR maximum velocity ≥ 2.9 m/s (sensitivity, 90.9% vs 72.3% and specificity, 80.0% vs 80.0%, respectively). CONCLUSIONS In fetuses with TVD or Ebstein's anomaly, the postnatal outcome may be BV or NBV when the TR maximum velocity is 2.4-3.3 m/s. In such cases, by combining the TR maximum velocity with dP/dt ≥ 350 mmHg/s, BV after birth may be predicted with greater accuracy. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
Systemic chemotherapy has shown a significant survival benefit in patients with hepatocellular carcinoma (HCC). However, it is associated with various immune-related adverse events (irAEs). We report a case with grade 3 diarrhea and grade 2 colitis following systemic chemotherapy, successfully treated with prednisolone. An 89-year-old man was incidentally detected with a 140-mm hypervascular intrahepatic nodule on contrast-enhanced computed tomography (CECT). Washout of the contrast medium was also detected, and protein induced by vitamin K deficiency or antagonists-II (PIVKA-II) was elevated. Since the Albumin-Bilirubin (ALBI) grade was 2a without any distant metastasis, transarterial chemoembolization (TACE) was performed to treat the HCC, but several intrahepatic nodules were seen in both lobes. Therefore, the patient was treated with lenvatinib for 1 year and 4 months. A complete response according to modified Response Evaluation Criteria in Solid Tumors (mRECIST) criteria was achieved in 2 months; however, multiple hypervascular nodules were detected again. Since the ALBI grade was 1, a second round of chemotherapy with atezolizumab and bevacizumab was initiated. Although a complete response was achieved, the therapy was discontinued due to grade 3 diarrhea and grade 2 colitis after the sixth course. Based on the stool analysis and culture, CECT, and colonoscopy, the diagnosis was atezolizumab-associated colitis. Diarrhea was controlled following the oral administration of 0.5 mg/kg/day of prednisolone, and atezolizumab-bevacizumab therapy was successfully reinitiated without recurrence of colitis. The management of irAEs is important for a significant survival benefit. Systemic chemotherapy with atezolizumab and bevacizumab can be resumed despite a grade 3 irAE due to atezolizumab.

Abstract
The differential cross sections of the Σ^{-}p→Λn reaction were measured accurately for the Σ^{-} momentum (p_{Σ}) ranging from 470 to 650 MeV/c at the J-PARC Hadron Experimental Facility. Precise angular information about the Σ^{-}p→Λn reaction was obtained for the first time by detecting approximately 100 reaction events at each angular step of Δcosθ=0.1. The obtained differential cross sections show a slightly forward-peaking structure in the measured momentum regions. The cross sections integrated for -0.7≤cosθ≤1.0 were obtained as 22.5±0.68 [statistical error(stat.)] ±0.65 [systematic error(syst.)] mb and 15.8±0.83(stat)±0.52(syst) mb for 470<p_{Σ}(MeV/c)<550 and 550<p_{Σ}(MeV/c)<650, respectively. These results show a drastic improvement compared with past measurements of the hyperon-proton scattering experiments. They will play essential roles in updating the theoretical models of the baryon-baryon interactions.

Abstract
There are few case reports of hepatocellular carcinoma (HCC) metastasis to the skeletal muscle. A 78-year-old man developed a mass in the right shoulder. Washout of contrast medium during contrast-enhanced ultrasonography (CEUS) in both the primary HCC and the metastatic site was detected. Several nodules were scattered throughout the liver on an autopsy. In addition, the moderately differentiated HCC had metastasized to the right teres major muscle. Rare muscular metastasis should be considered if a hepatic tumor is moderately or poorly differentiated HCC. Early washout during CEUS is consistent with a pathological diagnosis of moderately or poorly differentiated HCC.

Abstract
X-ray spectroscopy of hadronic atoms is a powerful method to study strong interaction between hadrons and nuclei. At J-PARC, we have conducted two experiments, J-PARC E07 and E03, for hadronic atoms with a doubly strange hyperon, Ξ−, aiming at the world-first detection of their X-rays. The first measurement is performed as a byproduct of J-PARC E07 experiment with the hybrid emulsion technique. The second one, J-PARC E03, is a dedicated experiment for detection of Ξ− Fe atom X rays. The preliminary results and the present status of E07 and E03 are shown in this article. Future prospects of Ξ−-atomic X-ray spectroscopy are also discussed. A new measurement has been proposed for detecting Ξ− C atom X rays, where a novel Ξ− tracking method will be applied to realize an improved signal to noise ratio.

Abstract
A new hyperon-proton scattering experiment, dubbed J-PARC E40, was performed to measure differential cross sections of the Σ+p, Σ−p elastic scatterings and the Σ−p → Λn scattering by identifying a lot of Σ particles in the momentum ranging from 0.4 to 0.8 GeV/c produced by the π±p → K+Σ± reactions. We successfully measured the differential cross sections of these three channels with a drastically improved accuracy with a fine angular step. These new data will become important experimental constraints to improve the theories of the two-body baryon-baryon interactions. Following this success, we proposed a new experiment to measure the differential cross sections and spin observables by using a highly polarized Λ beam for providing quantitative information on the ΛN interaction. The results of three Σp channels and future prospects of the Λp scattering experiment are described.

Abstract
Abstract
microRNAs modulate gene expression in various cancer types, and their profiles differ in healthy and cancer groups of people and they represent a warning sign for various cancer scenarios. Identification of tumor-specific microRNAs presents a powerful opportunity to potentially reduce cancer mortality through early detection. In order to achieve early detection through population screening, noninvasive approaches are needed to complement and improve upon current strategies for urothelial cancer (UC) screening. Since all microRNAs in the blood cannot be transferred from donor to recipient cells during single blood circulation, kidney filtration could pass some untransferred microRNAs from blood to urine, therefore urinary microRNAs might be used as biomarkers for the diagnosis of cancer. We investigated whether urine levels of microRNA can differentiate patients with UC from healthy individuals. Here, we successfully identified UC-related microRNA ensembles in urine through a combination of microfluidic microRNA extraction device and machine learning-based analysis.
We analyzed 93 urine samples from 27 UC patients and 66 healthy individuals (controls). An initial set of 74 microRNAs was selected by microarray microRNA profiling assay as biomarker candidates. Quantitative reverse-transcription PCR was used for further analysis to validate the expression of microRNAs.
We selected a group of 6 microRNAs for validation; (miR-6089, miR-4488, miR-4784, miR-26a-5p, miR-148a-3p, and miR-143-3p) were confirmed to be significantly different in UC and controls. We adopted a logistic regression model and successfully developed a classifier based on these 6 microRNAs, which showed remarkably high sensitivity (94%) and specificity (85%).
In summary, patients with UC have significantly different patterns of microRNA expression from healthy individuals. We identified a signature of 6 microRNAs as predictors that can differentiate patients with UC from those who are healthy. These microRNAs could be potentially developed as biomarkers for UC.

Abstract
Decreasing the partition coefficient (LogP) by the introduction of a hydrophilic group is the conventional approach for improving the aqueous solubility of drug candidates, but is not always effective. Since melting point is related to aqueous solubility, we and other groups have developed alternative strategies to improve solubility by means of chemical modification to weaken intermolecular interaction in the solid state, thereby lowering the melting point and increasing the solubility. Here, we show that converting the symmetrical molecular structure of the clinically used estrogen receptor (ER) antagonist cyclofenil (1) into asymmetrical form by introducing an alkyl group enhances the aqueous solubility. Among the synthesized analogs, the chiral methylated analog (R)-4c shows the highest solubility, being 3.6-fold more soluble than 1 even though its hydrophobicity is increased by the methylation. Furthermore, (R)-4c also showed higher membrane permeability than 1, while retaining a comparable metabolic rate, and equivalent biological activity of the active forms (R)-13a to 2. Further validation of this strategy using lead compounds having symmetric structures is expected.

Abstract
BACKGROUND/AIM The association between MHC class I polypeptide-related sequence A (MICA) and hepatocellular carcinoma (HCC) development was identified in our previous genome-wide association study. Decreasing soluble MICA (sMICA) through MICA sheddases suppression facilitates natural killer (NK) cell-mediated cytotoxicity. The expression of ADAM9 in HCC has been correlated with poor prognosis, and our recent study showed that its suppression contributes to cancer elimination by decreasing sMICA. MATERIALS AND METHODS Human HCC cell line PLC/PRF/5 and HepG2 cells were used. sMICA levels were measured by ELISA. Expression of retinoid X receptors (RXRs) and retinoic acid receptors (RARs) was knocked down by siRNA. RESULTS In our screening of FDA-approved drugs in vitro, retinoids were found to be efficient ADAM9 and ADAM10 inhibitors. Treatment with retinoids reduced sMICA levels in human HCC cells. Interestingly, the effects were abrogated by depletion of the retinoid receptor RXRα. CONCLUSION Retinoids can be potential novel agents for HCC treatment.

Abstract
In an emulsion-counter hybrid experiment performed at J-PARC, a Ξ^{-} absorption event was observed which decayed into twin single-Λ hypernuclei. Kinematic calculations enabled a unique identification of the reaction process as Ξ^{-}+^{14}N→_{Λ}^{10}Be+_{Λ}^{5}He. For the binding energy of the Ξ^{-} hyperon in the Ξ^{-}-^{14}N system a value of 1.27±0.21 MeV was deduced. The energy level of Ξ^{-} is likely a nuclear 1p state which indicates a weak ΞN-ΛΛ coupling.

Abstract
Aqueous solubility is a key requirement for small-molecule drug candidates. Here, we investigated the regioisomer-physicochemical property relationships of disubstituted benzenes. We found that meta-isomers bearing non-flat substituents tend to possess the lowest melting point and the highest thermodynamic aqueous solubility among the regioisomers. The examination of pharmaceutical compounds containing a disubstituted benzene moiety supported the idea that the introduction of a non-flat substituent at the meta position of a benzene substructure would be a promising approach for medicinal chemists aiming to improve the thermodynamic aqueous solubility of drug candidates, even though it might not be universally effective.

Abstract
Abstract
Background
Skeletal muscle atrophy is an independent prognostic predictor for patients with chronic heart failure, and the concept of sarcopenia is drawing attention. Furthermore, the importance of not only muscle mass but also intramuscular fat (IMF) has been pointed out. However, there is a lack of consensus on the implications of ectopic fat for the prognosis in patients with non-ischemic cardiomyopathy.
Purpose
We investigated whether ectopic fat in the thigh affects the prognosis with non-ischemic cardiomyopathy.
Methods
We recruited 105 patients who were diagnosed with non-ischemic cardiomyopathy by cardiac catheterization and echocardiographic date between September 2017 and November 2019. Finally 73 patients with reduced EF (EF 40% or less) enrolled in this prospective study. Functional status was evaluated by using cardiopulmonary exercise test at baseline. All patients were measured quantity of epicardial fat and thigh IMF percentage (%IMF) using computed tomography scan. Demographic, laboratory and echocardiographic date were collected from the patients' medical records. Clinical endpoints were unexpected readmission.
Results
During the follow-up period 18 patients had adverse events. The %IMF was significantly higher in the group with adverse events than without (5.57±5.70 and 3.02±2.44%, respectively; p<0.01). Spearman correlation coefficient analysis showed a modest correlation between %IMF and lower limb extension strength (Spearman r=−0.280; p=0.0315), but there was no significant correlation between %IMF and exercise tolerance such as anaerobic threshold and peak oxygen uptake. Patients were divided into 2 groups according to the median values of %IMF. Kaplan-Meier analysis demonstrated that events were significantly higher in the high %IMF group (log-rank p=0.033). Multivariate Cox regression analysis adjusted for left ventricular end-diastolic diameter and peak ventricular oxygen consumption found %IMF as an independent factor of adverse events (hazard ratio 1.545; 95% confidential interval 1.151–2.087; p=0.004).

Abstract
Background
Epicardial adipose tissue (EAT) has been recognized to contribute inflammatory activity and atherosclerosis. On the other hand, it has been reported that the volume of EAT is lower in non-ischemic heart failure (HF) patients than healthy individuals. However, the difference in regional muscle-adipose distribution including EAT between HF with preserved ejection fraction (HFpEF) and HF reduced ejection fraction (HFrEF) has not been investigated. In addition, we investigated whether distribution of body composition contributed to exercise capacity.
Methods
The study included 105 non-ischemic HF patients diagnosed by cardiac catheterization between September 2017 and November 2019. Epicardial, abdominal and thigh muscle and adipose tissue volume were measured by computed tomography (CT), and exercise tolerance was evaluated by symptom-limited cardiopulmonary exercise test.
Results
Patients were divided into 2 groups according to the left ventricular ejection fraction, ≥40% as HFpEF (n=28) or <40% as HFrEF (n=77). There was no significant difference comorbidity, including hypertension, dyslipidemia, chronic kidney disease, and body mass index. Plasma B-type natriuretic peptide level was significantly higher in HFrEF than HFpEF group (146.2 vs 393.2 pg/ml, p<0.01), whereas, high-sensitive troponin T level was not different between two groups. Although there was no significant difference in BMI between two groups, the volume of EAT was significantly higher in HFpEF than HFrEF group (81.8 vs 136.4 ml, p=0.01). On the other hand, HFpEF had more thigh adipose tissue compared with HFrEF group (54.6 vs 42.1 ml, p=0.03). There were negative correlations between EAT volume and parameters of exercise capacity such as anaerobic threshold (r=−0.42, p<0.01) and peak VO2 (r=−0.32, p<0.01). Muscle volume itself does not corelate with these parameters.
Conclusion
In patient with nonischemic HF, the pattern of regional adipose distribution may have important role in pathologically. HFpEF and HFrEF has different pattern despite similar body mass index. These differences may be related to impaired exercise tolerance in these 2 different types of HF.

Abstract
Synthetic sensing materials (artificial receptors) are some of the most attractive components of chemical/biosensors because of their long-term stability and low cost of production. However, the strategy for the practical design of these materials toward specific molecular recognition in water is not established yet. For the construction of artificial material-based chemical/biosensors, the bottom-up assembly of these materials is one of the effective methods. This is because the driving forces of molecular recognition on the receptors could be enhanced by the integration of such kinds of materials at the 'interfaces', such as the boundary portion between the liquid and solid phases. Additionally, the molecular assembly of such self-assembled monolayers (SAMs) can easily be installed in transducer devices. Thus, we believe that nanosensor platforms that consist of synthetic receptor membranes on the transducer surfaces can be applied to powerful tools for high-throughput analyses of the required targets. In this review, we briefly summarize a comprehensive overview that includes the preparation techniques for molecular assemblies, the characterization methods of the interfaces, and a few examples of receptor assembly-based chemical/biosensing platforms on each transduction mechanism.

Abstract
Exploring new strategies for simple and on-demand methods of manipulating the sensing ability of sensor devices functionalized with artificial receptors embedded in a molecular assembly is important to realizing high-throughput on-site sensing systems based on integrated and miniaturized devices such as field-effect transistors (FETs). Although FET-based chemical sensors can be used for rapid, quantitative, and simultaneous determination of various desired analytes, detectable targets in conventional FET sensors are currently restricted owing to the complicated processes used to prepare sensing materials. In this study, we investigated the relationship between the sensing features of FETs and the nanostructures of mixed self-assembled monolayers (mSAMs) for the detection of biomolecules. The FET devices were systematically functionalized using mixtures of benzenethiol derivatives (4-mercaptobenzoic acid and benzenethiol), which changed the nanostructure of the SAMs formed on gold sensing electrodes. The obtained cross-reactivity in the FETs modified with the mSAMs was derived from the multidimensional variations of the SAM characteristics. Our successful demonstration of continuous control of the molecular recognition ability in the FETs by applying the mSAM system could lead to the development of next-generation versatile analyzers, including chemical sensor arrays for the determination of multiple analytes anytime, anywhere.

Abstract
The gyromagnetic factor of the low-lying E=251.96(9) keV isomeric state of the nucleus ^{99}Zr was measured using the time-dependent perturbed angular distribution technique. This level is assigned a spin and parity of J^{π}=7/2^{+}, with a half-life of T_{1/2}=336(5) ns. The isomer was produced and spin aligned via the abrasion-fission of a ^{238}U primary beam at RIKEN RIBF. A magnetic moment |μ|=2.31(14)μ_{N} was deduced showing that this isomer is not single particle in nature. A comparison of the experimental values with interacting boson-fermion model IBFM-1 results shows that this state is strongly mixed with a main νd_{5/2} composition. Furthermore, it was found that monopole single-particle evolution changes significantly with the appearance of collective modes, likely due to type-II shell evolution.

Abstract
BACKGROUND Intra-operative cell salvage is not routinely used during cesarean delivery because it is not cost-effective for patients at low risk of hemorrhage and there are theoretical concerns about amniotic fluid embolism. Some guidelines recommend using leukocyte depletion filters to decrease the risk of amniotic fluid embolism before re-infusing salvaged blood, but these filters are not available in Japan. We compared the efficacy and safety of leukocyte depletion and micro-aggregate filters in combination with intra-operative cell salvage during cesarean delivery. METHODS Blood was collected in a Cell Saver 5 reservoir during cesarean delivery. Four samples were collected: pre-wash, post-wash, post-filtration with a leukocyte depletion filter and post-filtration with a micro-aggregate filter. Each sample was analyzed for amniotic fluid markers of zinc coproporphyrin-1 and sialyl-Tn, for fetal hemoglobin, and the sample underwent pathological examination for white blood cells and squamous cells. Post-filtration samples were compared using paired t-tests with P <0.05 indicating statistical significance. RESULTS Zinc coproporphyrin-1 and sialyl-Tn were negative at almost all sample points. Squamous cells decreased by 59.1% post-wash and 91.2% post-filtration using a leukocyte depletion filter. Leukocyte depletion filters removed 99.7% of white blood cells and were more effective in removing white blood cells than micro-aggregate filters (P=0.02). CONCLUSION Leucocyte depletion filters are more effective in removing white blood cells and squamous cells than micro-aggregate filters, and their introduction for intra-operative cell salvage during cesarean delivery should be considered in Japanese clinical practice.

Abstract
The biological process of pearl formation is an ongoing research topic, and a number of genes associated with this process have been identified. However, the involvement of microRNAs (miRNAs) in biomineralization in the pearl oyster, Pinctada fucata, is not well understood. In order to investigate the divergence and function of miRNAs in P. fucata, we performed a transcriptome analysis of small RNA libraries prepared from adductor muscle, gill, ovary, and mantle tissues. We identified 186 known and 42 novel miRNAs in these tissues. Clustering analysis showed that the expression patterns of miRNAs were similar among the somatic tissues, but they differed significantly between the somatic and ovary tissues. To validate the existence of the identified miRNAs, nine known and three novel miRNAs were verified by stem-loop qRT-PCR using U6 snRNA as an internal reference. The expression abundance and target prediction between miRNAs and biomineralization-related genes indicated that miR-1990c-3p, miR-876, miR-9a-3p, and novel-3 may be key factors in the regulatory network that act by controlling the formation of matrix proteins or the differentiation of mineralogenic cells during shell formation in mantle tissue. Our findings serve to further clarify the processes underlying biomineralization in P. fucata.

Abstract
Phosphatidylserine (PS) has skewed distributions in the plasma membrane and is preferentially located in the inner leaflet of normal cells. Tumour cells, however, expose PS at the outer leaflet of cell surfaces, thereby potentially modulating the bio-signalling of cells. Interestingly, exosomes - or, more properly, small extracellular vesicles (sEVs) - which are secreted from tumour cells, are enriched with externalized PS, have been proposed as being involved in the progression of cancers, and could be used as a marker for tumour diagnostics. However, the sEV fractions prepared from various methods are composed of different subtypes of vesicles, and knowledge about the subtypes enriched with exposed PS is still limited. Here, we differentiated sEVs from cancer cell lines by density gradient centrifugation and characterized the separated fractions by using gold-labelling of PS in atomic force microscopy, thrombin generation assay, size and zeta potential measurements, and western blot analysis. These analyses revealed a previously unreported PS+-enriched sEV subtype, which is characterized by a lower density than that of canonical exosomes (1.06 g/ml vs. 1.08 g/ml), larger size (122 nm vs. 105 nm), more negative zeta potential (-28 mV vs. -21 mV), and lower abundance of canonical exosomal markers. The identification of the PS-exposed subtype of sEVs will provide deeper insight into the role of EVs in tumour biology and enhance the development of EV-based tumour diagnosis and therapy.

Abstract
Piwi-interacting RNAs (piRNAs) belong to a recently discovered class of small non-coding RNAs whose best-understood function is repressing transposable element activity. Most piRNA studies have been conducted on model organisms and little is known about piRNA expression and function in mollusks. We performed high-throughput sequencing of small RNAs extracted from the mantle, adductor muscle, gill, and ovary tissues of the pearl oyster, Pinctada fucata. RNA species with sequences of approximately 30 nt were widely expressed in all tissues. Uridine at the 5' terminal and protection from β-elimination at the 3' terminal suggested that these were putative piRNAs. A total of 18.0 million putative piRNAs were assigned to 2.8 million unique piRNAs, and 35,848 piRNA clusters were identified. Mapping to the reference genome showed that 25% of the unique piRNAs mapped to multiple tandem loci on the scaffold. Expression patterns of the piRNA clusters were similar within the somatic tissues, but differed significantly between the somatic and gonadal tissues. These findings suggest that in pearl oysters piRNAs have important and novel functions beyond those in the germ line.

Abstract
An electron paramagnetic resonance (EPR)-based method for noninvasive three-dimensional extracellular pH mapping was developed using a pH-sensitive nitroxyl radical as an exogenous paramagnetic probe. Fast projection scanning with a constant magnetic field sweep enabled the acquisition of four-dimensional (3D spatial +1D spectral) EPR images within 7.5 min. Three-dimensional maps of pH were reconstructed by processing the pH-dependent spectral information on the images. To demonstrate the proposed method of pH mapping, the progress of extracellular acidosis in tumor-bearing mouse legs was studied. Furthermore, extracellular pH mapping was used to visualize the spatial distribution of acidification in different tumor xenograft mouse models of human-derived pancreatic ductal adenocarcinoma cells. The proposed EPR-based pH mapping method enabled quantitative visualization of regional changes in extracellular pH associated with altered tumor metabolism.

Abstract
We report on the first observation of γ rays emitted from an sd-shell hypernucleus, _{Λ}^{19}F. The energy spacing between the ground state doublet, 1/2^{+} and 3/2^{+} states, of _{Λ}^{19}F is determined to be 315.5±0.4(stat)_{-0.5}^{+0.6}(syst) keV by measuring the γ-ray energy of the M1(3/2^{+}→1/2^{+}) transition. In addition, three γ-ray peaks are observed and assigned as E2(5/2^{+}→1/2^{+}), E1(1/2^{-}→1/2^{+}), and E1(1/2^{-}→3/2^{+}) transitions. The excitation energies of the 5/2^{+} and 1/2^{-} states are determined to be 895.2±0.3(stat)±0.5(syst) and 1265.6±1.2(stat)_{-0.5}^{+0.7}(syst) keV, respectively. It is found that the ground state doublet spacing is well described by theoretical models based on existing s- and p-shell hypernuclear data.

Abstract
AIM Autotaxin (ATX) is a secreted enzyme that is considered to be associated with liver damage as well as fibrosis. This study assessed the ability of ATX to diagnose liver fibrosis in patients with chronic hepatitis B virus (HBV) infection. METHODS Serum ATX levels were retrospectively evaluated in 101 treatment-naïve patients with HBV-related chronic hepatitis or cirrhosis, all of whom had undergone liver biopsy at our hospital. RESULTS Serum ATX concentration increased significantly according to liver fibrosis stage in overall (r = 0.46, P < 0.0001), male (r = 0.55, P < 0.0001), and female (r = 0.52, P = 0.0006) patient groups. When analyzed by gender, serum ATX was one of the most reliable markers for all fibrosis stages compared with other tested non-invasive markers, which included hyaluronic acid, type IV collagen 7S, aspartate aminotransferase-to-platelet ratio index, and fibrosis index based on four factors, according to receiver operating characteristic curve analysis. CONCLUSION Based on this histologically proven data, ATX represents a novel non-invasive biomarker for liver fibrosis in HBV-infected patients.

Abstract
Abstract
Background: Cancer stem cells (CSC) are good sources of tumor initiation, heterogeneity, progression, and metastasis because of their unique characteristics. Several potential markers for CSCs have been suggested for breast cancer, including CD44+/CD24−/low, aldehyde dehydrogenase 1 (ALDH1), and epithelial cell adhesion molecule/epithelial-specific antigen. We previously reported that ALDH1 gene expression is related to aggressive phenotypes and poor prognosis in breast cancers. In this study, we conducted differential analysis of mRNA expression in ALDH1-positive breast cancer to identify genes associated with CSC. Next, we performed basic and clinical studies of one gene.
Methods: Messenger RNA was isolated from ALDH1-positive cells and ALDH1-negative cells in 5 ALDH1-positive breast cancers. Microarray analysis revealed that several genes were significantly associated with the ALDH1 gene. Among them, we examined a long non-coding RNA of H19 in this study. We evaluated the effect of H19 on CSCs using RNA interference and a sphere formation assay using two cell lines, HCC1937 and iCSCL10A cells. We also investigated H19 expression in 192 surgical specimens by in situ hybridization and analyzed the relationship between H19 expression and clinic pathological findings in breast cancer patients.
Results: Through in vitro experiments, we confirmed that suppression of H19 reduced sphere formation in both HCC1937 and iCSCL10A cells. Among surgical specimens, 48 samples (25%) expressed H19. We verified thatH19 positivity was significantly higher in ALDH1-positive cases than in ALDH1-negative cases (68% vs 9.7%, p < 0.001). H19 was significantly highly expressed in triple-negative breast cancer (TNBC) (46%) compared with other subtypes: luminal (33%), luminal-HER2 (6%), and HER2-enriched subtype (15%). H19-positive patients showed significantly worse prognosis (5-year disease-free survival 75.8% vs 91.5%, p = 0.001 and 5-year overall survival 88.7% vs 97.7%, p = 0.002). The effect of H19 expression on prognosis was the most significant in TNBC compared to in other subtypes (5-year disease-free survival 63.6% vs 88.9%, p = 0.038).
Conclusions: H19 is clearly associated with CSCs and correlated with poor prognosis in breast cancer patients, particularly TNBC. Our future studies will investigate the role of H19 in maintaining the nature of CSCs and protein-coding genes associated with H19.

Abstract
PurposeTo determine the correlation of the degree of aniseikonia with the retinal displacements and metamorphopsia in patients that have undergone successful epiretinal membrane (ERM) surgery.MethodsSubjects were 28 eyes with an ERM in 28 patients. The New Aniseikonia Test (NAT) and M-CHARTS were used to quantify the degree of preoperative and postoperative aniseikonia and metamorphopsia. We also evaluated the distance between the intersections of 2 sets of retinal vessels situated vertically or horizontally by using spectral-domain optical coherence tomography (SD-OCT) images in 28 patients.ResultsThe vertical score of M-CHARTS (MV) was not significantly improved, but the horizontal score of M-CHARTS (MH) was significantly improved at 1 week, 1 month, and 3 months postoperatively. The preoperative NAT score was significantly correlated with the preoperative MH. The NAT score at 3 months was significantly correlated with the MH at 3 months and the MV at 3 months. The preoperative NAT score was significantly correlated with the ratio of the vertical retinal displacement at 1 month and at 3 months after surgery. However, the NAT scores did not improve significantly at any postoperative times.ConclusionsThe degree of aniseikonia was significantly correlated with the degree of metamorphopsia and the tangential displacement of the retina after ERM surgery. Aniseikonia is difficult to improve and metamorphopsia may be a more sensitive parameter to detect the functional recovery after successful ERM surgery.

Abstract
Regeneration of blood vessels (neovascularization) is critical for gastric ulcer (GU) healing. The contributions of bone marrow-derived endothelial progenitor cells (BMD-EPCs) to neovascularization during GU healing are not fully elucidated. Our specific aims were to determine whether in GU, BMD-EPCs are incorporated into blood vessels of GU granulation tissue jointly with ECs, thus forming hybrid vessels; or, form separate vessels consisting of only BMD-EPCs. GUs were induced in rats by serosal application of acetic acid. Vascular cast studies were performed at 7, 21 and 60 days after GU induction and tissue specimens were immunostained for CD34, CD133, VEGFR2, and SDF-1 at 14 days. Human relevance was determined using archival human GU specimens. In rat GU granulation tissue BMD-EPCs constituted 28 ± 3% of all cells lining newly formed blood vessels, and were nested between fully differentiated ECs. In rat GU granulation tissue, expression of stromal derived factor-1 (SDF-1) - the major chemoattractant for BMD-EPCs was strongly upregulated. In human GU specimens, BMD-EPCs were also present in granulation tissue constituting 34 ± 3% of all cells lining blood vessels and jointly formed hybrid vessels with differentiated ECs. Our study uncovered that BMD-EPCs incorporate into newly formed blood vessels in GU granulation tissue; and, together with ECs of pre-existing vessels, contribute to and support neovascularization through vasculogenesis. This study is the first demonstration that vasculogenesis occurs during GU healing in both humans and in rats.

Abstract
Gold nanoparticles (AuNPs) have recently attracted attention as clinical agents for enhancing the effect of radiotherapy in various cancers. Although radiotherapy is a standard treatment for cancers, invasive recurrence and metastasis are significant clinical problems. Several studies have suggested that radiation promotes the invasion of cancer cells by activating molecular mechanisms involving integrin and fibronectin (FN). In this study, polyethylene-glycolylated AuNPs (P-AuNPs) were conjugated with Arg–Gly–Asp (RGD) peptides (RGD/P-AuNPs) to target cancer cells expressing RGD-binding integrins such as α5- and αv-integrins. RGD/P-AuNPs were internalized more efficiently and colocalized with integrins in the late endosomes and lysosomes of MDA-MB-231 cells. A combination of RGD/P-AuNPs and radiation reduced cancer cell viability and increased DNA damage compared to radiation alone in MDA-MB-231 cells. Moreover, the invasive activity of breast cancer cell lines after radiation treatment was significantly inhibited in the presence of RGD/P-AuNPs. Microarray analyses revealed that the expression of FN in irradiated cells was suppressed by combined use of RGD/P-AuNPs. Reduction of FN and downstream signaling may be involved in suppressing radiation-induced invasive activity by RGD/P-AuNPs. Our study suggests that RGD/P-AuNPs can target integrin-overexpressing cancer cells to improve radiation therapy by suppressing invasive activity in addition to sensitization. Thus, these findings provide a possible clinical strategy for using AuNPs to treat invasive breast cancer following radiotherapy.

Abstract
BACKGROUND & AIMS Primary biliary cholangitis (PBC) is an autoimmune liver disease characterized by portal inflammation and immune-mediated destruction of intrahepatic bile ducts that often leads to liver decompensation and liver failure. Although the biochemical response to ursodeoxycholic acid (UDCA) can predict disease outcome in PBC, few biomarkers have been identified as prognostic tools applicable prior to UDCA treatment. We therefore sought to identify such indicators of long-term outcome in PBC in the Japanese population. METHODS The prebiopsy serum samples and subsequent clinical data of 136 patients with PBC treated with UDCA were analysed over a median follow-up period of 8.8 years. Serum levels of biomarkers related to microbial translocation (sCD14, EndoCAb and I-FABP) were measured along with those of 33 cytokines and chemokines and additional auto-antibodies. Associations between the tested parameters and the clinical outcomes of liver decompensation and liver-related death/liver transplantation were evaluated using the Cox proportional hazards model with stepwise methods and Kaplan-Meier analysis. RESULTS Elevated levels of serum IL-8, and sCD14 before UDCA therapy were significantly associated with both liver decompensation and liver-related death/liver transplantation. In multivariate analyses, IL-8≥46.5 pg/mL or sCD14≥2.0 μg/mL at enrolment demonstrated the same results. Kaplan-Meier analysis also revealed IL-8 and sCD14 to be significantly associated with a poor outcome. sCD14 was significantly correlated with IL-8. EndoCAb and I-FABP were not related to disease outcome. CONCLUSIONS Serum IL-8 and sCD14 levels before UDCA therapy represent noninvasive surrogate markers of prognosis in patients with PBC.

Abstract
AIM Past hepatitis B virus (HBV) infection is considered a risk factor for hepatocarcinogenesis, but the clinicopathological characteristics of non-B non-C hepatocellular carcinoma (NBNC-HCC) excluding past HBV infection have not been investigated. This study aimed to clarify the clinicopathological features of strictly defined NBNC-HCC. METHODS Among HCC patients who underwent surgical resection at our affiliated hospitals in Nagano prefecture, Japan, between 1996 and 2012, 77 were negative for serum anti-HBV core/surface antibodies in addition to HBV surface antigen and anti-hepatitis C virus antibody without signs of autoimmune liver disease, Wilson disease, or hemochromatosis. These patients were divided into the alcohol intake-positive group (ethanol intake >20 g/day, n = 31), non-alcoholic fatty liver group (steatosis >5% and ethanol intake <20 g/day, n = 30), and cryptogenic group (no ethanol intake or steatosis, n = 16). Preoperative clinical parameters, tumor and background liver pathology, and prognosis were analyzed. RESULTS Advanced fibrosis and steatosis were detected in 64% and 60% of all patients, respectively. Approximately 85% of the alcohol intake-positive patients had advanced fibrosis. Non-alcoholic fatty liver HCC subjects had the highest body mass index and prevalence of diabetes, but 30-40% had none to mild fibrosis. The cryptogenic group of HCC patients had the lowest incidence of accompanying hepatic inflammation/fibrosis but the largest tumor size. Recurrence/survival rates were comparable among the groups. CONCLUSIONS Liver fibrosis and steatosis are risk factors of HCC regardless of past HBV infection and ethanol consumption. The present results also indicate the possibility of hepatocarcinogenesis independent of hepatic steatosis, inflammation and fibrosis, ethanol intake, and past HBV infection.

Abstract
Abstract
Purpose: This study aimed to evaluate response to neoadjuvant chemotherapy (NAC) for patients with hormone receptor-negative (HR-negative) breast cancer (BC) to identify subtypes that require anthracycline treatment.
Methods: In total, 103 patients with operable HR-negative BC were registered. They were randomely assigned to administration of 6 cycles of docetaxel (75mg/m2) and cyclophosphamide (600 mg/m2) (TC6) or 3 cycles of 5-fluorouracil (500 mg/m2), epirubicin (100mg/m2), and cyclophosphamide (500mg/m2) followed by 3 cycles of docetaxel (100mg/m2) (FEC-D). Cytokeratin (CK) 5/6 and EGFR expression were used to identify basal and non-basal triple-negative (TN) BC. The primary endpoint was pathological complete response (pCR); secondary endpoints were safety, breast-conserving surgery, disease-free survival, and overall survival. Predictive factors of pCR for each regimen were also evaluated.
Results:
The pCR rate was 36% for FEC-D and 25.5% for TC6, which did not differ significantly (P=0.265). When TN BC was subdivided into basal and non-basal subtypes, the pCR rate in the basal subtype was significantly lower for TC6 (13.6%) than for FEC-D (42.9%) (P=0.033), but did not significantly differ in the non-basal (TC6, 36.4%; FEC-D, 25.0%) and HER2-positive (TC6, 41.7%; FEC-D, 35.7%) cases.
The relative dose intensities of epirubicin and docetaxel in FEC-D and docetaxel in TC6 were 96.3±13.0%, 93.5±14.6%, and 93.9±16.3% (mean±SD), respectively. Occurrence of grade ≥2 adverse events was significant in FEC-D-treated patients. Poor appetite (P<0.001), nausea (P<0.001), vomiting (P<0.001), dysgeusia (P=0.03), and fatigue (P=0.05) were significantly more common for FEC-D than TC6. Patients treated with FEC-D experienced significantly more febrile neutropenia and anemia (P=0.016 and 0.017, respectively).
The rates of breast-conserving surgery were 68.0 and 72.3% for FEC-D and TC6, respectively (P=0.641).
Patients achieved pCR had better DFS (log rank test, P = 0.287) and OS (log rank test, P = 0.069), though not significant. Patients treated with FEC-D had better DFS (log rank test, P = 0.107) and OS (log rank test, P = 0.159), though not significant. Among patients with TN BC, those treated with FEC-D had significantly better DFS (log rank test, P = 0.016) and OS (log rank test, P = 0.034) than treated with TC6.
Low ALDH1 expression and high topo IIα protein expression were strongly correlated with pCR in FEC-D, with odds ratios (ORs) of 4.33 [95% CI, 1.02–18.38] and 4.08 [0.97–17.2], respectively. ALDH1 was also associated with pCR in TC, OR=3.50 [0.84–14.6]. Other factors, including age, tumor size, nodal status, tumor grade, Ki67, p53, and TOP 2A status were not associated with pCR in either regimen.
Conclusions:We found that TC6 was less effective than FEC-D for treating HR-negative BC because it was insufficient for TNBC, particularly for basal BC. This suggests that anthracycline is more important than taxane for basal BC. Additionally, ALDH1 could be a marker for resistance to conventional chemotherapy.

Abstract
AIM Serum glycosylated Wisteria floribunda agglutinin-positive Mac-2 binding protein (WFA+ -M2BP) is a reliable, non-invasive marker of liver fibrosis. This study assessed the ability of WFA+ -M2BP to diagnose liver fibrosis in patients with chronic hepatitis B virus (HBV) infection and evaluated WFA+ -M2BP as a predictor of hepatocellular carcinoma (HCC) development. METHODS Serum WFA+ -M2BP values were retrospectively evaluated in 112 treatment-naïve patients with HBV-related chronic hepatitis and cirrhosis who had undergone liver biopsy at our hospital. RESULTS Serum WFA+ -M2BP levels were significantly related with liver fibrosis (r = 0.3725, P = 0.001). Fibrosis stage F2, F3, and F4 had a cut-off index of 0.94, 1.26, and 1.26, respectively. For diagnosing F ≥ 2 fibrosis, the area under the receiver-operating characteristic curve for WFA+ -M2BP was 0.713 and comparable with those of other non-invasive fibrosis markers, such as hyaluronic acid, type IV collagen 7S, aspartate aminotransferase-to-platelet ratio index, fibrosis-4 index, serum albumin, and platelet count. Multivariate analysis identified male, WFA+ -M2BP ≥0.71, alanine aminotransferase ≥80 IU/L, and platelet count <14.5 × 109 /L as independent risk factors for the development of HCC in patients with HBV infection. CONCLUSIONS Serum WFA+ -M2BP values appear to be useful for assessing liver fibrosis stage and are independently associated with HCC development in patients with chronic HBV infection.

Abstract
AIM To assess whether surrogate biomarkers of endotoxemia were correlated with the histological features of nonalcoholic fatty liver disease (NAFLD).
METHODS One hundred twenty-six NAFLD patients who had undergone percutaneous liver biopsy were enrolled. Serum lipopolysaccharide (LPS)-binding protein (LBP) and anti-endotoxin core immunoglobulin G (EndoCab IgG) antibody concentrations at the time of liver biopsy were measured using the enzyme-linked immunosorbent assays to examine for relationships between biomarker levels and histological scores.
RESULTS Serum LBP concentration was significantly increased in nonalcoholic steatohepatitis (NASH) patients as compared with nonalcoholic fatty liver (NAFL) subjects and was correlated with steatosis (r = 0.38, P < 0.0001) and ballooning scores (r = 0.23, P = 0.01), but not with the severity of lobular inflammation or fibrosis. Multivariate linear regression analysis revealed that LBP was associated with steatosis score and circulating C-reactive protein, aspartate aminotransferase, and fibrinogen levels. Serum EndoCab IgG concentration was comparable between NASH and NAFL patients. No meaningful correlations were detected between EndoCab IgG and histological findings.
CONCLUSION LBP/EndoCab IgG were not correlated with lobular inflammation or fibrosis. More accurate LPS biomarkers are required to stringently assess the contribution of endotoxemia to conventional NASH.
