Abstract
The microtubule-associated protein MAP1B has been implicated in axonal growth and brain development. We found that MAP1B is highly expressed in the most aggressive and deadliest breast cancer subtype, triple-negative breast cancer (TNBC), but not in other subtypes. Expression of MAP1B was found to be highly correlated with poor prognosis. Depletion of MAP1B in TNBC cells impairs cell migration and invasion concomitant with a defect in tumorigenesis. We found that MAP1B interacts with key components for invadopodia formation, cortactin, and Tks5, the latter of which is a PtdIns(3,4)P2-binding and scaffold protein that localizes to invadopodia. We also found that Tks5 associates with microtubules and supports the association between MAP1B and α-tubulin. In accordance with their interaction, depletion of MAP1B leads to Tks5 destabilization, leading to its degradation via the autophagic pathway. Collectively, these findings suggest that MAP1B is a convergence point of the cytoskeleton to promote malignancy in TNBC and thereby a potential diagnostic and therapeutic target for TNBC.

Abstract
BACKGROUND This study aimed to evaluate VE of primary, first, and second booster ancestral-strain monovalent mRNA COVID-19 vaccination against symptomatic infections and severe diseases in Japan. METHODS We conducted a test-negative case-control study. We included medically attended episodes and hospitalizations involving individuals aged ≥ 16 with signs and symptoms from July to November 2022, when Omicron BA.5 was dominant nationwide. To evaluate VE, we calculated adjusted ORs of vaccination among test-positive versus test-negative individuals using a mixed-effects logistic regression. RESULTS For VE against symptomatic infections among individuals aged 16 to 59, VE of primary vaccination at > 180 days was 26.1% (95% CI: 10.6-38.8%); VE of the first booster was 58.5% (48.4-66.7%) at ≤ 90 days, decreasing to 41.1% (29.5-50.8%) at 91 to 180 days. For individuals aged ≥ 60, VE of the first booster was 42.8% (1.7-66.7%) at ≤ 90 days, dropping to 15.4% (-25.9-43.2%) at 91 to 180 days, and then increasing to 44.0% (16.4-62.5%) after the second booster. For VE against severe diseases, VE of the first and second booster was 77.3% (61.2-86.7%) at ≤ 90 days and 55.9% (23.4-74.6%) afterward. CONCLUSION mRNA booster vaccination provided moderate protection against symptomatic infections and high-level protection against severe diseases during the BA.5 epidemic in Japan.

Abstract
OBJECTIVES This study aimed to clarify the relationship between the oral assessment guide (OAG), a simple method for assessing oral function and poor nutrition in gastric cancer patients and investigate the reduction of oral mucositis through appropriate oral function management. SUBJECTS AND METHODS Gastric cancer patients who underwent chemotherapy at the Nagoya Ekisaikai Hospital between January 2015 and December 2020 were evaluated. The prognostic nutritional index (PNI), as the objective variable, was used to assess nutritional status. The explanatory variables were sex, age, smoking status, body mass index (BMI), number of remaining teeth, cancer stage, albumin level, C-reactive protein level, white blood cell count and the OAG score. RESULTS PNI was significantly associated with age, number of remaining teeth, cancer stage and the OAG score (p < 0.05) among the 217 patients. There were significant differences in age, BMI, cancer stage and the OAG score among the patients. An abnormal BMI and an advanced cancer stage were more common in older patients, and abnormal OAG scores were associated with a lower PNI. CONCLUSIONS For gastric cancer patients undergoing postoperative chemotherapy, worse oral functional status is associated with worse PNI and nutritional status.

Abstract
The photocatalytic properties of anodic oxides on a newly developed TiNbSn and commonly used Ti6Al4V alloys as biomaterials were investigated. The alloys were anodized in an electrolyte of sodium tartrate acid with H2O2 at a high voltage and the mechanism of the photocatalytic and antiviral activities was studied. The anodized TiNbSn and Ti6Al4V exhibited highly crystallized rutile TiO2 and poorly crystallized anatase TiO2, respectively. X-ray photoelectron spectroscopy analysis revealed the presence of oxides of the alloying elements in addition to TiO2. The anodized TiNbSn exhibited higher activities than Ti6Al4V, and electron spin resonance spectra indicated that the number of hydroxyl radicals (⋅OH) generated from the anodized TiNbSn was higher than that from the anodized Ti6Al4V. The results can be explained by two possible mechanisms: the higher crystallinity of TiO2 on TiNbSn than that on the Ti6Al4V reduces the number of charge recombination sites and generates abundant ⋅OH; charge separation in the anodic oxide on TiNbSn due to the electronic band structure between TiO2 and the oxides of alloying elements enhances photo activities. The excellent photoinduced characteristics of the anodized TiNbSn are expected to contribute to the safe and reliable implant treatment.

Abstract
Abstract
Background
Magnification endoscopy and magnification narrow-band imaging are image enhanced endoscopy technologies that may allow for the diagnosis of advanced neoplasia in the GI tract on the basis of imaging characteristics. Recently, the Unified Magnifying Endoscopic Classification (UMEC) has been developed, which unified the criteria for the esophagus, stomach, and colon. UMEC divides optical diagnosis into one of the three categories: non-neoplastic, intramucosal neoplasia, and deep submucosal invasive cancer.
Purpose
The objective of this study is to educate North American endoscopists on the use of the UMEC schema, and to ascertain performance of the UMEC framework among North American endoscopists.
Method
Using UMEC, five North American endoscopists (>1000 procedures) without prior training in magnifying endoscopy independently diagnosed previously collected endoscopic image set of the esophagus, stomach, and colon. The endoscopists were trained on the use of UMEC via an eleven-minute training video with exemplars of each element of UMEC from esophagus, stomach, and colon. All endoscopists were blinded to white-light and non-magnifying NBI findings as well as histopathological diagnosis. The diagnostic performance of UMEC was assessed while using the gold standard histopathology as a reference.
Result(s)
A total of 299 gastrointestinal lesions (77 esophagus, 92 stomach, and 130 colon) were assessed using UMEC. For esophageal squamous cell carcinoma, the sensitivity, specificity, and accuracy for all 5 endoscopists ranged from 65.2% (95% CI: 50.9–77.9) to 87.0% (95% CI: 75.3–94.6), 77.4% (95% CI: 60.9–89.6) to 96.8% (95% CI: 86.8–99.8), and 75.3% to 87.0%, respectively. For gastric adenocarcinoma, the sensitivity, specificity, and accuracy for all 5 endoscopists ranged from 94.9% (95% CI: 85.0–99.1) to 100%, 52.9% (95% CI: 39.4–66.2) to 92.2% (95% CI: 82.7–97.5), and 73.3% to 93.3%, respectively. For colorectal adenocarcinoma, the sensitivity, specificity, and accuracy for all 5 endoscopists ranged from 76.2% (95% CI: 62.0–87.3) to 83.3% (95% CI: 70.3–92.5), 89.7% (95% CI: 82.1–94.9) to 97.7% (95% CI: 93.1–99.6), and 86.8% to 90.7%, respectively.

Conclusion(s)
UMEC is a simple and practical classification that can be used to introduce and educate endoscopists to magnification narrow-band imaging and optical diagnosis.

Abstract
BACKGROUND Evaluating COVID-19 vaccine effectiveness (VE) domestically is crucial for assessing and determining national vaccination policy. This study aimed to evaluate VE of mRNA COVID-19 vaccines in Japan. METHODS We conducted a multicenter test-negative case-control study. The study comprised individuals aged ≥16 visiting medical facilities with COVID-19-related signs or symptoms from 1 January to 26 June 2022, when Omicron BA.1 and BA.2 were dominant nationwide. We evaluated VE of primary and booster vaccination against symptomatic SARS-CoV-2 infections and relative VE of booster compared with primary. RESULTS We enrolled 7,931 episodes, including 3,055 test positive. The median age was 39, 48.0% were male, and 20.5% had underlying medical conditions. In individuals aged 16 to 64, VE of primary vaccination within 90 days was 35.6% (95% CI, 19.0-48.8%). After booster, VE increased to 68.7% (60.6-75.1%). In individuals aged ≥65, VE of primary and booster was 31.2% (-44.0-67.1%) and 76.5% (46.7-89.7%), respectively. Relative VE of booster compared with primary vaccination was 52.9% (41.0-62.5%) in individuals aged 16 to 64 and 65.9% (35.7-81.9%) in individuals aged ≥65. CONCLUSIONS During BA.1 and BA.2 epidemic in Japan, mRNA COVID-19 primary vaccination provided modest protection. Booster vaccination was necessary to protect against symptomatic infections.

Abstract
BackgroundSystemic sclerosis (SSc) is an autoimmune disease that is characterized by systemic vasculopathy and fibrosis. Pulmonary hypertension (PH), defined as elevated pulmonary arterial pressure (PAP), is one of the leading causes of death of SSc1. In recent years, various therapies have been developed to target each of the pathogenesis of SSc – autoimmunity, vasculopathy, and fibrosis. Accordingly, treatment strategies based on risk stratification for PH progression are aspired; however, prediction of changes in PAP in diverse patients with SSc has not been established2.ObjectivesTo visualize the patterns of PAP elevation in SSc and to identify the clinical characteristics of each trajectory, by applying latent trajectory modeling for PAP measured repeatedly by echocardiography.MethodsThis was a multicenter, retrospective cohort study conducted at four referral hospitals in Kyoto, Japan. Patients with SSc who visited the study site between April 2008 and March 2021 and had at least three echocardiographic measurements of systolic pulmonary arterial pressure (sPAP) were included in this study. Follow-up concluded in March 2021. A group-based trajectory model3 was applied to the change in sPAP over time, and individual patients were classified into distinct subgroups that followed similar trajectories. The number and shape of the trajectories were estimated based on adequacy, goodness of fit, parsimony, and interpretability of the model. Clinical plausibility was assessed by comparing PH-free survival, i.e., time to either PH or death, for each trajectory. Multinomial logistic regression analysis was performed for baseline clinical characteristics associated with trajectory assignment.ResultsA total of 236 patients with a total of 1097 sPAP measurements were included. We identified five trajectories following the quadratic function as “rapid progression (n=9, 3.8%)”, “early elevation (n=30, 12.7%)”, “mid elevation (n=54, 22.9%)”, “late elevation (n=24, 10.2%)”, and “low stable (n=119, 50.4%)”. Each trajectory, in this order, showed earlier elevation of sPAP and shorter PH-free survival (Figure 1). In the multinomial logistic regression (with the “low stable” as reference), cardiac involvement was associated with the “rapid progression” (adjusted odds ratio [OR] 28.9, 95% confidence interval [CI] 3.21–259.5), diffuse cutaneous SSc was associated with the “early elevation” (OR 4.08, 95% CI 1.27–13.1), anti-centromere antibody positive was associated with the “mid elevation” (OR 4.50, 95% CI 1.11–18.2), and older age of onset was associated with the above three trajectories.ConclusionThe pattern of changes in pulmonary artery pressure over time in SSc can be classified into five distinct trajectories. Each trajectory differed in baseline clinical characteristics and outcomes.References[1]Pokeerbux MR, et al.

Abstract
In the mouse testis, sperm originate from spermatogonial stem cells (SSCs). SSCs give rise to spermatogonial progenitors, which expand their population until entering the differentiation process that is precisely regulated by a fixed time-scaled program called the seminiferous cycle. Although this expansion process of progenitors is highly important, its regulatory mechanisms remain unclear. NANOS3 is an RNA-binding protein expressed in the progenitor population. We demonstrated that the conditional deletion of Nanos3 at a later embryonic stage results in the reduction of spermatogonial progenitors in the postnatal testis. This reduction was associated with the premature differentiation of progenitors. Furthermore, this premature differentiation caused seminiferous stage disagreement between adjacent spermatogenic cells, which influenced spermatogenic epithelial cycles, leading to disruption of the later differentiation pathway. Our study suggests that NANOS3 plays an important role in timing progenitor expansion to adjust to the proper differentiation timing by blocking the retinoic acid (RA) signaling pathway.

Abstract
Bisphenol A (BPA) has been shown to exhibit various toxic effects, including the induction of reproductive disorders. Generally, BPA is converted to conjugated metabolites, leading to bio-inactivation. On the other hand, the toxicity of conjugated metabolites is not fully understood. Notably, the placenta develops the sulfate-sulfatase pathway, which transports and reactivates sulfated steroids. Therefore, we investigated the potential adverse effects of the BPA-sulfate conjugate (BPA-S) on human placenta-derived BeWo cytotrophoblasts. In the present study, high-concentration BPA-S (100 μM) induced significant inhibition of BeWo growth, with effects similar to those seen with unconjugated BPA (100 μM and 100 nM). This growth inhibition was restored by treatment of the cells with an inhibitor of the organic anion-transporting peptides (OATPs) (bromosulphophthalein) or with a sulfatase (STS) inhibitor (STX64). BeWo exhibits expression of the genes encoding OATP1A2 and OATP4A1 as known sulfated steroid transporters and STS, suggesting that BPA-S suppresses cell growth activity via the sulfate-sulfatase pathway. In addition, cell cycle analysis revealed that BPA-S (100 μM) increased the fraction of cytotrophoblasts in the G2/M phases and significantly decreased the accumulation of the transcript encoding Aurora kinase A (AURKA), which is a critical regulator of cellular division. These results suggested that BPA-S triggers cell cycle arrest and inhibits proliferation of BeWo cytotrophoblasts by decreased AURKA, an effect that is mediated by the sulfate-sulfatase pathway. Overall, these findings provide insights into the reactivation of sulfated endocrine-disrupting chemicals and subsequent adverse effects.

Abstract
Mammalian syntaxin 17 (Stx17) has several roles in processes other than membrane fusion, including in mitochondrial division, autophagosome formation and lipid droplet expansion. In contrast to conventional syntaxins, Stx17 has a long C-terminal hydrophobic region with a hairpin-like structure flanked by a basic amino acid-enriched C-terminal tail. Although Stx17 is one of the six ancient SNAREs and is present in diverse eukaryotic organisms, it has been lost in multiple lineages during evolution. In the present study, we compared the localization and function of fly and nematode Stx17s expressed in HeLa cells with those of human Stx17. We found that fly Stx17 predominantly localizes to the cytosol and mediates autophagy, but not mitochondrial division. Nematode Stx17, on the other hand, is predominantly present in mitochondria and facilitates mitochondrial division, but is irrelevant to autophagy. These differences are likely due to different structures in the C-terminal tail. Non-participation of fly Stx17 and nematode Stx17 in mitochondrial division and autophagy, respectively, was demonstrated in individual organisms. Our results provide an insight into the evolution of Stx17 in metazoa. This article has an associated First Person interview with the first author of the paper.

Abstract
ATP11C, a member of the P4-ATPase family, translocates phosphatidylserine and phosphatidylethanolamine at the plasma membrane. We previously revealed that its C-terminal splice variant ATP11C-b exhibits polarized localization in motile cell lines, such as MDA-MB-231 and Ba/F3. In the present study, we found that the C-terminal cytoplasmic region of ATP11C-b interacts specifically with ezrin. Notably, the LLxY motif in the ATP11C-b C-terminal region is crucial for its interaction with ezrin as well as its polarized localization on the plasma membrane. A constitutively active, C-terminal phosphomimetic mutant of ezrin was colocalized with ATP11C-b in polarized motile cells. ATP11C-b was partially mislocalized in cells depleted of ezrin alone, and exhibited greater mislocalization in cells simultaneously depleted of the family members ezrin, radixin and moesin (ERM), suggesting that ERM proteins, particularly ezrin, contribute to the polarized localization of ATP11C-b. Furthermore, Atp11c knockout resulted in C-terminally phosphorylated ERM protein mislocalization, which was restored by exogenous expression of ATP11C-b but not ATP11C-a. These observations together indicate that the polarized localizations of ATP11C-b and the active form of ezrin to the plasma membrane are interdependently stabilized.

Abstract
The formation and the chemical characterization of single atoms of dubnium (Db, element 105), in the form of its volatile oxychloride, was investigated using the on‐line gas phase chromatography technique, in the temperature range 350–600 °C. Under the exactly same chemical conditions, comparative studies with the lighter homologues of Group 5 in the Periodic Table clearly indicate the volatility sequence being NbOCl3 > TaOCl3 ≥ DbOCl3. From the obtained experimental results, thermochemical data for DbOCl3 were derived. The present study delivers reliable experimental information for theoretical calculations on chemical properties of transactinides.

Abstract
In response to cholesterol deprivation, SCAP escorts SREBP transcription factors from the endoplasmic reticulum to the Golgi complex for their proteolytic activation, leading to gene expression for cholesterol synthesis and uptake. Here, we show that in cholesterol-fed cells, ER-localized SCAP interacts through Sac1 phosphatidylinositol 4-phosphate (PI4P) phosphatase with a VAP-OSBP complex, which mediates counter-transport of ER cholesterol and Golgi PI4P at ER-Golgi membrane contact sites (MCSs). SCAP knockdown inhibited the turnover of PI4P, perhaps due to a cholesterol transport defect, and altered the subcellular distribution of the VAP-OSBP complex. As in the case of perturbation of lipid transfer complexes at ER-Golgi MCSs, SCAP knockdown inhibited the biogenesis of the trans-Golgi network-derived transport carriers CARTS, which was reversed by expression of wild-type SCAP or a Golgi transport-defective mutant, but not of cholesterol sensing-defective mutants. Altogether, our findings reveal a new role for SCAP under cholesterol-fed conditions in the facilitation of CARTS biogenesis via ER-Golgi MCSs, depending on the ER cholesterol.

Abstract
In mammalian cloning by somatic cell nuclear transfer (SCNT), the treatment of reconstructed embryos with histone deacetylase (HDAC) inhibitors improves efficiency. So far, most of those used for SCNT are hydroxamic acid derivatives-such as trichostatin A-characterized by their broad inhibitory spectrum. Here, we examined whether mouse SCNT efficiency could be improved using chlamydocin analogues, a family of newly designed agents that specifically inhibit class I and IIa HDACs. Development of SCNT-derived embryos in vitro and in vivo revealed that four out of five chlamydocin analogues tested could promote the development of cloned embryos. The highest pup rates (7.1-7.2%) were obtained with Ky-9, similar to those achieved with trichostatin A (7.2-7.3%). Thus, inhibition of class I and/or IIa HDACs in SCNT-derived embryos is enough for significant improvements in full-term development. In mouse SCNT, the exposure of reconstructed oocytes to HDAC inhibitors is limited to 8-10 h because longer inhibition with class I inhibitors causes a two-cell developmental block. Therefore, we used Ky-29, with higher selectivity for class IIa than class I HDACs for longer treatment of SCNT-derived embryos. As expected, 24-h treatment with Ky-29 up to the two-cell stage did not induce a developmental block, but the pup rate was not improved. This suggests that the one-cell stage is a critical period for improving SCNT cloning using HDAC inhibitors. Thus, chlamydocin analogues appear promising for understanding and improving the epigenetic status of mammalian SCNT-derived embryos through their specific inhibitory effects on HDACs.

Abstract
Environmental water quality monitoring plays an important role in human health risk assessments for pharmaceuticals in water and pollutant source control. A new chemical detection method was developed to enhance molecular selectivity and portability by combining the molecularly imprinted technique and an electroosmotic pump (EOP), which requires only a small pump, batteries and stopwatch in principle. Selective chemical adsorption on the surface-modified EOP decreases the pumping performance of EOP due to a decrease in the surface electric charge. For proof of concept, the microfabricated EOPs with chemical surface treatment were used to investigate the effects of surface chemical change on pumping performance. The microfluidic EOP of a size of 20 mm × 20 mm × 1 mm was modified by an interval immobilization method using the template of 4-(tributylammonium-methyl)-benzyltributylammonium chloride (TBTA) and evaluated by measuring EOF. The pumping performance of the surface-modified EOP was decreased by the selective adsorption of TBTA to a two-point recognition site on the EOP surfaces. The relationships between the flow rate and the TBTA concentration were fitted to the Langmuir equation. The EOP can selectively detect the model substance even in a mixture solution with a different chemical compound. This molecular imprinted EOP does not require large and expensive instruments for driving the device and chemical detection, which can be applied to a portable analytical device for onsite analysis.

Abstract
The AIDH is a project as a historical epidemiology. The AIDH aims to collect, maintain, and manage past epidemiological materials and to offer these materials to persons who are interested in the history and in the fields of tropical medicine and global health. In this paper, we introduce our purpose and activities and show a hypothesis about lymphatic filariasis with Brugia malayi in Japan as a case of historical epidemiology. We hope to build fruitful ties between historians and scholars of tropical medicine and global health workers through an interdisciplinary approach to the history of control of infectious diseases.

Abstract
Androgen receptor (AR) has a key role in the development and progression of prostate cancer, and AR antagonists are used for its remedy. Recently, carborane derivatives, which are carbon-containing boron clusters have attracted attention as new AR ligands. Here we determined the force field parameters of 10-vertex and 12-vertex p-carborane to facilitate in silico drug design of boron clusters. Then, molecular dynamics (MD) simulations of complexes of AR-carborane derivatives were performed to evaluate the parameters and investigate the influences of carborane derivatives on the three-dimensional structure of AR. Energy profiles were obtained using quantum chemical calculations, and the force-field parameters were determined by curve fitting of the energy profiles. The results of MD simulations indicated that binding of the antagonist-BA341 changed some hydrogen-bond formations involved in the structure and location of helix 12. Those results were consistent with previously reported data. The determined parameters are also useful for refining the structure of the carborane-receptor complex obtained by docking simulations and development of new ligands with carborane cages not only for AR but also for various receptors.

Abstract
Abstract
Background
The optimal anticoagulant regimen for elderly AF has not been well elucidated, because this population, especially the very elderly (≥85 years), have not been sufficiently represented in most randomized controlled clinical trials for stroke prevention in non-valvular AF (NVAF).
Purpose
The ANAFIE registry was designed to evaluate the real-world anticoagulant treatment status of elderly (≥75 years) NVAF patients including >8,000 very elderly patients. In this main analysis of the ANAFIE, the incidence of stroke or systemic embolic events (stroke/SEE), and major bleeding were compared between warfarin (WF) and direct oral anticoagulants (DOACs).
Methods
A total of 33,018 NVAF patients aged ≥75 years was enrolled in the ANAFIE, and followed for 2 years. The incidence of stroke/SEE and major bleeding by type of anticoagulants (WF and all DOACs) was estimated using Kaplan-Meier method. Hazard ratio (HR) and 95% confidence interval (95% CI) were calculated by Cox proportional hazard model.
Results
In the analysis set of 32,099 patients, the mean age was 81.5 years. 23,738 (74%) were <85 years and 8,361 (26.0%) were ≥85 years. 92.5% of the whole population used anticoagulants including WF (27.6%) or DOACs (72.3%). The ratio of each DOAC was dabigatran 7.8%, rivaroxaban 21.5%, apixaban 26.9% and edoxaban 16.1%. Stroke/SEE and major bleeding was observed in 396 patients (1.24/100 patient-years [py]) and 279 patients (0.87/100py). The time in therapeutic range for patients <85 years and ≥85 years in the WF group was 76.7% and 72.2%, respectively. The incidence of stroke/SEE was numerically lower in patients taking any DOAC vs. WF regardless of age group (<85 years [HR 0.83] and ≥85 years [HR 0.71]). Major bleeding was also lower vs. WF in both age groups (<85 years [HR 0.60] and ≥85 years [HR 0.65]).
Conclusion
In elderly NVAF patients enrolled in the ANAFIE registry, the incidence of stroke/SEE and major bleeding was lower in patients taking a DOAC compared with WF for all patients ≥75 years, even for very elderly patients.

Abstract
Abstract
Background
Bleeding is associated with shorter life expectancy during anticoagulant treatment in atrial fibrillation (AF) patients. Prior studies showed bleeding during anticoagulant treatment occurred more frequently in elderly AF patients than in younger AF patients. HAS-BLED score is a risk assessment tool for bleeding. However, since it was developed from the database of patients with warfarin, it has not been clarified whether this score is applicable in the era of direct oral anticoagulant (DOACs), especially for elderly AF patients.
Purpose
All Nippon AF In the Elderly (ANAFIE) registry was designed to obtain real-world information regarding patients with non-valvular AF (NVAF) aged ≥75 years, including current status of anticoagulant therapy and prognosis. The present study aimed to determine factors that associate with major bleeding for elderly NVAF patients using the dataset of ANAFIE registry conducted in Japan.
Methods
Total of 32,099 patients aged ≥75 years with NVAF were enrolled in ANAFIE registry, and followed for 2 years. Incidence rates of major bleeding for total population, <85 years old group and ≥85 years old group were estimated using Kaplan-Meier method. Cox proportional hazards model was used to determine independent predictors of major bleeding. The factors included in the model were selected by backward elimination procedure.
Results
Mean age was 81.5 years. 23,738 (74.0%) was <85 years old and 8,361 (26.0%) was ≥85 years old. 92.5% of whole population used anticoagulants including warfarin (27.6%) or DOACs (72.3%). Major bleeding occurred in 279 patients at 12 months with 189 in <85 years and 90 in ≥85 years old group. The cumulative incidence rate of major bleeding at 12 months by Kaplan-Meier method was 0.9% in whole patients, and was slightly higher in ≥85 years than in <85 years old group (1.1% vs 0.8%). In multivariate analysis of the whole patients, history of major bleeding (hazard ratio [HR]: 2.17), severe hepatic dysfunction (HR: 3.62), malignancy (HR: 1.52), falling within a year (HR: 2.07), antiplatelet use (HR: 1.37) and warfarin use (HR: 1.81) emerged as independent predictors of major bleeding. Severe hepatic dysfunction (HR: 9.17), HbA1c <6.0% (HR: 2.19) and dementia (HR: 2.00) were associated with major bleeding in patients only in aged ≥85 years. On the other hand, proton pump inhibitor use (HR: 1.36), creatinine clearance <30 mL/min (HR: 1.53) and polypharmacy (HR: 1.61) were associated with major bleeding only in those aged <85 years.
Conclusion
Among elderly (≥75 years old) Japanese NVAF patients in the era of DOACs, prior major bleeding, severe hepatic dysfunction, malignancy, falling within a year, antiplatelet use and warfarin use were identified as independent predictors of major bleeding. Impact of some predictors differed between the 2 age groups (<85 years vs ≥85 years).

Abstract
Abstract
Background
Since prevalence of atrial fibrillation (AF) is increasing by aging, AF in elderly has been recognized as a big burden to keep long lasting healthy life worldwide. CHADS2 and CHA2DS2-VASc scores are commonly used for stroke risk assessment for AF, but predictors for elderly was not well elucidated, especially for very elderly (≥85 years old) patients.
Purpose
All Nippon AF In the Elderly (ANAFIE) registry was designed to evaluate a real-world treatment status of elderly (≥75 years old) non-valvular AF (NVAF) patients, including anticoagulant therapy and outcomes. The present analysis aimed to identify factors for stroke/systemic embolic events (SEE) of elderly NVAF patients using the dataset of ANAFIE registry, which was conducted in Japan.
Methods
Total of 32,099 patients aged ≥75 years with NVAF were enrolled in ANAFIE registry, and followed for 2 years. Incidence of stroke/SEE for total population, <85 years old group and ≥85 years old group was estimated using Kaplan-Meier method. Cox proportional hazards model was used to determine independent predictors of stroke/SEE. The factors included in the model were selected by backward elimination procedure.
Results
Mean age was 81.5 years. 23,738 (74%) was <85 years old and 8,361 (26%) was ≥85 years old. Women were more prevalent in ≥85 years old than in <85 years old group (53.2 vs 39.0%). Mean CHADS2 and CHA2DS2-VASc scores in the ≥85 years group were 3.0 and 4.7, and 2.8 and 4.4 in the <85 years group, respectively. 92.5% of whole population used anti-coagulants including warfarin (27.6%) or direct oral anticoagulants (DOACs) (72.3%). Stroke/SEE occurred in 396 patients at 12 month with 256 in <85 years old and 140 in ≥85 years old group. The cumulative incidence rate of stroke/SEE by Kaplan-Meier method at 12 months was 1.2% in the whole patients, and was higher in ≥85 years than in <85 years old group (1.7% vs 1.1%). In the multivariate analysis using the whole patients, age ≥85 years (hazard ratio [HR]: 1.27), history of major bleeding (HR: 1.93), persistent AF (HR: 1.64), longstanding persistent and permanent AF (HR: 1.61), high systolic blood pressure (130-<140 [HR: 1.43], ≥140 [HR: 1.44]), prior stroke (HR: 2.09), dementia (HR: 1.34), creatinine clearance <30 mL/min (HR: 1.82) emerged as independent predictors. Independent predictors for stroke/SEE were almost similar between <85 and ≥85 years old group except hypertension and diabetes. High blood pressure was associated with stroke/SEE only in patients aged <85 years, and high blood sugar was only associated in patients aged ≥85 years.
Conclusion
Among elderly NVAF patients in the era of DOACs, higher age (≥85 years), type of AF, prior major bleeding, high blood pressure, prior stroke, dementia, and low creatinine clearance were identified as independent predictors of stroke/SEE. The blood pressure and blood sugar control differently affected <85 years vs ≥85 years old group.

Abstract
Advances in low-dimensional superconductivity are often realized through improvements in material quality. Apart from a small group of organic materials, there is a near absence of clean-limit two-dimensional (2D) superconductors, which presents an impediment to the pursuit of numerous long-standing predictions for exotic superconductivity with fragile pairing symmetries. We developed a bulk superlattice consisting of the transition metal dichalcogenide (TMD) superconductor 2H-niobium disulfide (2H-NbS2) and a commensurate block layer that yields enhanced two-dimensionality, high electronic quality, and clean-limit inorganic 2D superconductivity. The structure of this material may naturally be extended to generate a distinct family of 2D superconductors, topological insulators, and excitonic systems based on TMDs with improved material properties.

Abstract
Highly enantioselective organocatalytic construction of spirochromans containing a tetrasubstituted stereocenter was developed. Intramolecular oxy-Michael addition was catalyzed with a bifunctional cinchona alkaloid thiourea catalyst. A variety of spirochroman compounds containing a tetrasubstituted stereocenter were obtained with excellent enantioselectivities of up to 99% enantiomeric excess. The reaction was applied to the asymmetric formal synthesis of (-)-(R)-cordiachromene.

Abstract
Pear psyllids (Hemiptera: Psylloidea: Psyllidae: Cacopsylla spp.) belong to the most serious pests of pear (Pyrus spp.). They damage pear trees by excessive removal of phloem sap, by soiling the fruits with honeydew which, in turn, provides a substrate for sooty mould, and by transmission of Candidatus Phytoplasma spp., the causal agents of the pear decline disease. The morphological similarity, the presence of seasonal dimorphism that affects adult colour, size and wing morphology and uncritical use of species names, led to much confusion in the taxonomy of pear psyllids. As a result, pear psyllids have been frequently misidentified. Many of the entries attributed to Cacopsylla pyricola and other species in the GenBank are misidentifications which led to additional, unnecessary confusion. Here we analysed DNA barcodes of 11 pear psyllid species from eastern Asia, Europe and Iran using four mitochondrial gene fragments (COI 658 bp, COI 403 bp, COI-tRNAleu-COII 580 bp and 16S rDNA 452 bp). The efficiency of identification was notably high and considerable barcoding gaps were observed in all markers. Our results confirm the synonymies of the seasonal forms of Cacopsylla jukyungi ( = C. cinereosignata, winter form) and C. maculatili ( = C. qiuzili, summer form) previously suggested based on morphology. Some previous misidentifications (C. chinensis from China, Japan and Korea = misidentification of C. jukyungi; C. pyricola and C. pyrisuga from East Asia = misidentification of C. jukyungi and C. burckhardti, respectively; C. pyricola from Iran = misidentification of C. bidens, C. pyri and Cacopsylla sp.) are also corrected. There is no evidence for the presence of European pear psyllid species in East Asia.

Abstract
BACKGROUND Intraperitoneal chemotherapy using paclitaxel is considered an experimental approach for treating peritoneal carcinomatosis. This study aimed to determine the recommended dose, and to evaluate the clinical efficacy and safety, of the combination of intravenous gemcitabine, intravenous nab-paclitaxel and intraperitoneal paclitaxel in patients with pancreatic cancer and peritoneal metastasis. METHODS The frequencies of dose-limiting toxicities were evaluated, and the recommended dose was determined in phase I. The primary endpoint of the phase II analysis was overall survival rate at 1 year. Secondary endpoints were antitumour effects, symptom-relieving effects, safety and overall survival. RESULTS The recommended doses of intravenous gemcitabine, intravenous nab-paclitaxel and intraperitoneal paclitaxel were 800, 75 and 20 mg/m2 respectively. Among 46 patients enrolled in phase II, the median time to treatment failure was 6·0 (range 0-22·6) months. The response and disease control rates were 21 of 43 and 41 of 43 respectively. Ascites disappeared in 12 of 30 patients, and cytology became negative in 18 of 46. The median survival time was 14·5 months, and the 1-year overall survival rate was 61 per cent. Conversion surgery was performed in eight of 46 patients, and those who underwent resection survived significantly longer than those who were not treated surgically (median survival not reached versus 12·4 months). Grade 3-4 haematological toxicities developed in 35 of 46 patients, whereas non-haematological adverse events occurred in seven patients. CONCLUSION Adding intraperitoneal paclitaxel had clinical efficacy with acceptable tolerability.

Abstract
In this report, we present two cases in which benzodiazepines (BZDs) were able to be successfully reduced or discontinued by treatment with traditional Japanese herbal medicine (Kampo medicine), including Hangekobokuto (HKT). These two patients with long-term use of BZDs due to mental disorders suffered epigastric symptoms. After starting Kampo therapy including HKT, their epigastric symptoms were improved and they were able to reduce or discontinue the use of BZDs. This suggests that HKT is a potentially promising substitutive pharmacotherapy for patients with long-term use of BZDs. HKT should be considered as a treatment for patients with mental disorders who have taken BZDs for a long time and suffer from medically unexplained epigastric symptoms.

Abstract
Zearalenone (ZON), produced by Fusarium fungi, exhibits estrogenic activity. Livestock
can be exposed to ZON orally through contaminating feeds such as cereals, leading to
reproductive disorders such as infertility and miscarriage via endocrine system
disruption. However, the details of ZON metabolism remain unclear, and the mechanism of
its toxicity has not been fully elucidated. In this study, we investigated the kinetics of
ZON absorption and metabolism in rat segmented everted intestines. ZON absorption was
confirmed in each intestine segment 60 min after application to the mucosal buffer at 10
µM. Approximately half of the absorbed ZON was metabolized to
α-zearalenol, which tended to be mainly glucuronidated in intestinal cells. In the
proximal intestine, most of the glucuronide metabolized by intestinal cells was excreted
to the mucosal side, suggesting that the intestine plays an important role as a first drug
metabolism barrier for ZON. However, in the distal intestine, ZON metabolites tended to be
transported to the serosal side. Glucuronide transported to the serosal side could be
carried via the systemic circulation to the local tissues, where it could be reactivated
by deconjugation. These results are important with regard to the mechanism of endocrine
disruption caused by ZON.

Abstract
Avian glucose transporters (GLUT) responsible for insulin-responsive glucose uptake into adipocytes remain poorly characterized. We aimed to identify the insulin-responsive GLUT using primary culture of chicken adipocytes. Acute stimulation with 1 μM insulin for 20 min increased 2-deoxyglucose uptake, AKT protein phosphorylation, and GLUT1 protein levels on the plasma membrane of the chicken adipocytes, whereas pretreatment with 10 μM triciribine, an AKT inhibitor, canceled these effects. Furthermore, the insulin stimulation did not affect GLUT12 protein levels on the plasma membrane of the chicken adipocytes. Our results suggest that GLUT1 is an insulin-responsive GLUT in chicken adipocytes.

Abstract
Abstract
Background
The strategy of intravascular ultrasound (IVUS)-guided wiring for CTO PCI, that is, leading the second guidewire into the true lumen under observing by IVUS from subintimal space, is the last resort. We developed the angiography-based 3D wiring method. During establishment of the angiography-based 3D wiring method, we deduced that observation of the guidewire tip as well as the shaft named “The tip detection method” simplifies and facilitates 3D wiring under IVUS-guided wiring. Therefore, we produced New CTO IVUS which is the upgraded version of Navifocus WR IVUS by adding the pull-back transducer system. This pull-back system enables us to detect the tip as well as the shaft of the second guidewire in real time (tip detection method), which facilitates the 3D wiring technique under IVUS-guided wiring.
Objective
We evaluated the efficacy of the tip detection method during 3D wiring for CTO PCI with New CTO IVUS.
Method
We created a target pinpoint penetration model and performed the procedures using an experimental heartbeat model. The target (a tube with a lumen 0.6 mm in diameter) was placed in the distal part of a CTO 20 mm in length made of 2.5% agar. After the second guidewire (Conquest-12g) was advanced into the CTO lesion to within 5mm of the target using the angiography-based wiring, IVUS-guided wiring was performed by using Navifocus WR or New CTO IVUS each five times.
Result
The frequency of the puncture time was reduced using the new CTO IVUS compared to the Navifocus WR (1.7±0.8 vs. 28.8±23.2, p=0.17). The procedure time was significantly shorter using the new CTO IVUS compared to the Navifocus WR (103±61 vs. 459±373 seconds, p=0.04).
Conclusion
The tip detection method during 3D wiring with the new short tip IVUS with the pull-back system enables us to easily perform 3D wiring and will change the CTO PCI strategy.

Abstract
Abstract
Background
Atrial fibrillation (AF) is associated with increased mortality and morbidity. Modelling the risk of thrombosis, major bleeding and total mortality are often limited by the inadequate number of independent predictors.
Purpose
We compared the predictive accuracy of the decision-support tool framework and conventional risk score in AF patients.
Methods
We used data of AF patients enrolled into the nationwide AF registry. A random forest model was implemented to predict each outcome, and its predictive power was tested by a 5-fold cross-validation.
Results
We analyzed 7,937 patients with AF (age 70±10 years, female 31%). The type of AF was paroxysmal (37%), persistent (14%), and permanent (49%). The number of antithrombotic treatments were follows: warfarin only (n=5461), antiplatelet only (n=581), both warfarin and antiplatelet (n=1471) and no antithrombotic agents (424). The mean CHA2DS2-VASc score was 2.8±1.6 and HAS-BLED score was 2.7±1.2, respectively. We selected 20 from 50 clinical parameters and compared by the area-under-curve with the CHA2DS2-VASc score for thromboses and the HAS-BLED score for major bleeding. During the 2-year follow-up, 126 patients (1.6%) had thromboses, 140 (1.8%) had major bleeding, and 195 (2.5%) died. A random forest model had a higher value of the area-under-curve for predicting thromboses compared with the CHA2DS2-VASc (0.66 vs. 0.61, P<0.05), and had a significantly higher area-under-curve for major bleeding compared with the HAS-BLED (0.67 vs. 0.61, P<0.05). The area-under-curve for the all-cause mortality was 0.77.
Conclusions
A random forest model has a higher accuracy than conventional risk scheme in predicting thromboses and major bleeding, in addition to total mortality.

Abstract
Abstract
Background
Successful restoration of sinus rhythm (SR) by catheter ablation (CA) for persistent atrial fibrillation (AF) improves cardiac function, resulting in decrease of plasma brain natriuretic peptide (BNP) level. The exact significance and prognostic implications of this change have yet to be determined.
Purpose
To examine the impact of pre- and post-procedural BNP level on the clinical outcome after CA in patients with persistent AF and reduced left ventricular ejection fraction (LVEF).
Methods
Out of 242 patients with LVEF <50% who underwent first-time CA for persistent AF between March 2012 and September 2018 at our institute, we enrolled 137 patients (61±10 years, 83% male) whose plasma BNP level was available both at baseline and early after CA (during 1–3 month). We evaluated the impact of the BNP levels on future AF recurrence 3 months after CA as the primary endpoint. Additional secondary endpoints included heart failure (HF) hospitalization and cardiovascular death.
Results
All patients successfully restored SR at the end of CA. Within 3 months of a blanking period (BP), improvement of LVEF (from 39±10% to 65±12%, p<0.001) and reduction of BNP levels (from 178 [107–332] pg/ml to 42.3 [21.1–78.6] pg/ml, p<0.001) were observed. During the median follow-up of 21 months after BP, the incidence of AF recurrence, HF hospitalization, and cardiovascular death was 37% (n=50), 3% (n=4), and 1% (n=1), respectively. Cox proportional hazard regression analysis after adjustment for age and gender revealed that post-procedural BNP level was a significant predictor of the AF recurrence (hazard ratio [HR] per 100-pg/ml increase, 1.13; 95% confidence interval [CI], 1.02–1.25; p=0.023), but pre-procedural BNP level was not (1.02; 0.95–1.09; p=0.56). Receiver operating curve analysis determined the post-procedural BNP level of 55.5 pg/ml as the best cut-off value for predicting the AF recurrence, with area under the curve of 0.620 (95% CI, 0.534–0.702; p=0.018). The incidence of AF recurrence was significantly higher in patients with post-procedural BNP level >55.5 pg/ml (n=50) than the others (50% vs. 29%; HR, 3.99; 95% CI, 2.07–7.68; p<0.001). No patients with post-procedural BNP level ≤55.5 pg/ml experienced HF hospitalization and cardiovascular death (8% vs. 0% and 2% vs. 0%, p=0.006 and p=0.17, respectively)
Conclusions
Not pre-procedural but post-procedural BNP level early after CA predicted the future clinical outcome in patients with persistent AF and reduced LVEF. Decreased but still elevated BNP level after restoration of SR would identify the residual risk for developing unfavorable outcome.

Abstract
Invasive cancer cells degrade and invade into the extracellular matrix by expressing the matrix metalloproteinase MT1-MMP at invadopodia. Miyagawa et al. show that MT1-MMP uses the ER-Golgi SNARE Bet1 to facilitate its own transport to the plasma membrane through their interaction in a cholesterol-rich milieu. Metastasis is a major cause of cancer-related death. Membrane type 1–matrix metalloproteinase (MT1-MMP) is a critical protease for local invasion and metastasis. MT1-MMP is synthesized in the endoplasmic reticulum (ER) and transported in vesicles to invadopodia, specialized subdomains of the plasma membrane, through secretory and endocytic recycling pathways. The molecular mechanism underlying intracellular transport of MT1-MMP has been extensively studied, but is not fully understood. We show that MT1-MMP diverts the SNARE Bet1 from its function in ER-Golgi transport, to promote MT1-MMP trafficking to the cell surface, likely to invadopodia. In invasive cells, Bet1 is localized in MT1-MMP–positive endosomes in addition to the Golgi apparatus, and forms a novel SNARE complex with syntaxin 4 and endosomal SNAREs. MT1-MMP may also use Bet1 for its export from raft-like structures in the ER. Our results suggest the recruitment of Bet1 at an early stage after MT1-MMP expression promotes the exit of MT1-MMP from the ER and its efficient transport to invadopodia.

Abstract
ATP11C, a member of the P4-ATPase family, is a major phosphatidylserine (PS)-flippase located at the plasma membrane. ATP11C deficiency causes a defect in B-cell maturation, anemia and hyperbilirubinemia. Although there are several alternatively spliced variants derived from the ATP11C gene, the functional differences between them have not been considered. Here, we compared and characterized three C-terminal spliced forms (we designated as ATP11C-a, ATP11C-b and ATP11C-c), with respect to their expression patterns in cell types and tissues, and their subcellular localizations. We had previously shown that the C-terminus of ATP11C-a is critical for endocytosis upon PKC activation. Here, we found that ATP11C-b and ATP11C-c did not undergo endocytosis upon PKC activation. Importantly, we also found that ATP11C-b localized to a limited region of the plasma membrane in polarized cells, whereas ATP11C-a was distributed on the entire plasma membrane in both polarized and non-polarized cells. Moreover, we successfully identified LLXY residues within the ATP11C-b C-terminus as a critical motif for the polarized localization. These results suggest that the ATP11C-b regulates PS distribution in distinct regions of the plasma membrane in polarized cells.

Abstract
BACKGROUND AND AIMS T2 gallbladder cancer requires lymph node dissection for curative resection, whereas simple cholecystectomy is adequate to treat T1 gallbladder cancer. Hence, this study aimed to develop an accurate scoring system to preoperatively predict pT2 in gallbladder cancer. MATERIAL AND METHODS We retrospectively assessed data from 57 patients with suspected gallbladder cancer who underwent curative resection between September 2003 and May 2017. Six with apparent invasion of adjacent organs on preoperative images were excluded. We evaluated preoperative computed tomography, magnetic resonance and endoscopic ultrasonographic images, blood biochemistry, and the maximum standard uptake value in fluorodeoxyglucose-positron emission tomography images. We analyzed whether correlations between preoperative findings and the depth of tumor invasion could predict pT2. RESULTS The pathological diagnosis was gallbladder cancer in 30 (58.8%) patients, of whom 21 (69.9%) had pT2 or worse. Multivariate analyses selected carcinoembryonic antigen and tumor diameter as independent predictors of pT2 or worse (odds ratios = 1.741 and 1.098, respectively; 95% confidence intervals = 1.004-3.020 and 1.008-1.197, respectively). A regression formula was created using carcinoembryonic antigen and tumor diameter to calculate pT2 predictive scores. The area under the receiver operating characteristics curve of the pT2 predictive score was 0.873. CONCLUSION We created a scoring system to predict pT2 in gallbladder cancer using carcinoembryonic antigen and tumor diameter. The present findings suggested that carcinoembryonic antigen is important for the preoperative evaluation of gallbladder cancer.

Abstract
The effect of a preparation of heat-killed Gram-positive lactic acid bacteria Enterococcus faecalis 2001 (EF-2001) on oral candidiasis was evaluated by two studies. An in vitro study was performed to assess the inhibitory effect on mycelial growth of Candida strains isolated from a patient with oral candidiasis, and a clinical study was done in patients with oral candidiasis. In the in vitro study, EF-2001 inhibited mycelial growth of IT-1, a Candida strain isolated from a patient with oral candidiasis, at concentrations ≥2.34×109 cells/ml. An open clinical study was performed in 13 patients with oral candidiasis. The subjects took a powder containing 7.5×1011 heat-killed EF-2001 once a day before bedtime for seven consecutive days. In 11 of the 12 patients available for analysis (92%), the oral Candida load (cfu/swab) showed a significant decrease (P=0.01079, d=-0.437). There was a 55% decrease of Candida albicans and a 93.8% decrease of Candida glabrata. The following symptoms showed significant improvement: tinnitus (P=0.048, d=-0.462), cold feeling (P=0.048, d=-0.463), and depression (P=0.019, d=-0.34). In addition, 4 out of 26 oral symptoms tended to improve. These results suggest that EF-2001 significantly decreased the oral Candida load in patients with oral candidiasis by inhibiting mycelial growth and that EF-2001 is an effective treatment for oral candidiasis.

Abstract
Although they are known to share pathophysiological processes, the relationship between periodontitis and chronic obstructive pulmonary disease (COPD) is not fully understood. The aim of the present study was to test the hypothesis that periodontitis is associated with a greater risk of development of COPD, when smoking is taken into account. The analysis in a 5-y follow-up population-based cohort study was based on 900 community-dwelling Japanese adults (age: 68.8 ± 6.3 [mean ± SD], 46.0% male) without COPD aged 60 or older with at least 1 tooth. Participants were classified into 3 categories according to baseline periodontitis severity (no/mild, moderate, and severe). COPD was spirometrically determined by a fixed ratio of <0.7 for forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) and by FEV1/FVC below the lower limit of normal. Poisson regression was used to calculate the relative risk (RR) of developing COPD according to the severity of periodontitis. The population attributable fraction (PAF) was also calculated. During follow-up, 22 (2.4%) subjects developed COPD. Compared with no/mild periodontitis subjects, a significantly increased risk of COPD occurred among severe periodontitis subjects (RR = 3.55; 95% confidence interval [CI], 1.18 to 10.67), but no significant differences were observed between the no/mild and moderate categories (RR = 1.48; 95% CI, 0.56 to 3.90). After adjustment for potential confounders, including smoking intensity, the relationship between severe periodontitis and risk of COPD remained significant (RR = 3.51; 95% CI, 1.15 to 10.74). Likewise, there was a positive association of periodontitis severity with risk of COPD ( P for trend = 0.043). The PAF for COPD due to periodontitis was 22.6%. These data highlight the potential importance of periodontitis as a risk factor for COPD.
