Abstract
This study investigated the effect of a home-based computerized cognitive training program that utilizes a digital application for training abacus-based mental calculations, "SoroTouch," on the cognitive functions of healthy middle-aged and older people using a randomized controlled trial. The participants were 20 adults (aged 42-79 years) who were involved in community-based activities for dementia prevention held by a certain organization. The participants were assigned randomly to the intervention (SoroTouch) group or control group. The SoroTouch group received home-based cognitive training with SoroTouch, being asked to use the software every day for 6 months, while the control group did not receive any intervention. To investigate the effect of SoroTouch, CogEvo, a cognitive functions test battery utilizing a tablet device, was administered to all participants once per month during the 6-month intervention period. In addition, before and after the intervention, all participants were asked to take the CogEvo and the Japanese version of the Montreal Cognitive Assessment (MoCA-J). The analyses showed that the SoroTouch group did not improve total scores of the CogEvo and MoCA-J, but large group differences were observed in the two tasks of the CogEvo as follows: 'Follow the order' (modified Trail Making Test) at 2 months after the beginning of the intervention (group differences; 39.4, 95% confidence interval; 7.6-71.2) and 'Route 99' at 6 months (group differences; 39.6, 95% confidence interval; 4.9-74.4). These results provide evidence that a home-based computerized cognitive training program SoroTouch has the potential to improve working memory, attention and planning in healthy middle-aged and older adults.

Abstract
The emergence of highly infectious pathogens with their potential for triggering global pandemics necessitate the development of effective treatment strategies, including broad-spectrum antiviral therapies to safeguard human health. This study investigates the antiviral activity of emetine, dehydroemetine (DHE), and congeneric compounds against SARS-CoV-2 and HCoV-OC43, and evaluates their impact on the host cell. Concurrently, we assess the potential cardiotoxicity of these ipecac alkaloids. Significantly, our data reveal that emetine and the (-)-R,S isomer of 2,3-dehydroemetine (designated in this paper as DHE4) reduce viral growth at nanomolar concentrations (i.e., IC50 ∼ 50-100 nM), paralleling those required for inhibition of protein synthesis, while calcium channel blocking activity occurs at elevated concentrations (i.e., IC50 ∼ 40-60 µM). Our findings suggest that the antiviral mechanisms primarily involve disruption of host cell protein synthesis and is demonstrably stereoisomer specific. The prospect of a therapeutic window in which emetine or DHE4 inhibit viral propagation without cardiotoxicity renders these alkaloids viable candidates in strategies worthy of clinical investigation.

Abstract
OBJECTIVES To compare the discriminative capabilities for the manifestation of sarcopenia or physical frailty between serum creatinine- and cystatin C-derived indices among community-dwelling older adults. DESIGN Cross-sectional study. SETTING Primary Care and Community. PARTICIPANTS We utilized a subset of data from the Frail Elderly in the Sasayama-Tamba Area (FESTA) study, which was initiated in 2015 to gather comprehensive information on various health-related parameters among community-dwelling older individuals (age ≥65 years). MEASUREMENTS Five serum creatinine-cystatin C based indices including the Sarcopenia Index, the serum creatinine/cystatin C ratio, the disparity between serum cystatin-C-based and creatinine-based estimated GFR, the total body muscle mass index (TBMM), and the prediction equation for skeletal muscle mass index (pSMI) were employed. Sarcopenia and physical frailty were identified based on the Asian Working Group for Sarcopenia criteria and the revised Japanese version of the Cardiovascular Health Study criteria, respectively. The receiver operating characteristic (ROC) and logistic regression analyses were performed to assess the discriminative abilities of these tools. RESULTS In the analysis of 954 participants, 52 (5.5%) were identified with sarcopenia and 35 (3.7%) with physical frailty. Regarding sarcopenia discrimination, TBMM and pSMI both exhibited area under the curve (AUC) values exceeding 0.8 for both men and women. Concerning the identification of physical frailty, AUC values ranged from 0.61 to 0.77 for males and 0.50 to 0.69 for females. In the multivariate logistic regression analyses, only TBMM and pSMI consistently displayed associations with sarcopenia, irrespective of sex (P<0.001, respectively). On the other hand, no consistent associations were observed between the indices and physical frailty. CONCLUSIONS This study provides a robust association of a serum creatinine- and cystatin C-derived indices, especially TBMM and pSMI, with sarcopenia among community-dwelling older adults. Conversely, the application of these indices for the screening of physical frailty has its constraints, necessitating further investigation.

Abstract
Image-based deep learning (IBDL) is an advanced technique for predicting the surface irradiation conditions of laser surface processing technology. In pulsed-laser surface processing techniques, the number of superimposed laser shots is one of the fundamental and essential parameters that should be optimized for each material. Our primary research aims to build an adequate dataset using laser-irradiated surface images and to successfully predict the number of superimposed shots using the pre-trained deep convolutional neural network (CNN) models. First, the laser shot experiments were performed on copper targets using a nanosecond YAG laser with a wavelength of 532 nm. Then, the training data were obtained with the different superimposed shots of 1 to 1024 in powers of 2. After that, we used several pre-trained deep CNN models to predict the number of superimposed laser shots. Based on the dataset with 1936 images, VGG16 shows a high validation accuracy, higher sensitivity, and more than 99% precision than other deep CNN models. Utilizing the VGG16 model with high sensitivity could positively impact the industries' time, efficiency, and overall production.

Abstract
Background A high incidence (40-73%) of postoperative nausea and vomiting (PONV) has been reported following orthognathic surgery, and various risk factors have been associated with it. Identifying PONV risk factors based on initial onset time will help establish preventive measures. This study aimed to identify factors that are significantly related to PONV based on the initial onset time after orthognathic surgery. Methods This study included 590 patients who underwent orthognathic surgery. Multivariate logistic regression analysis was performed to identify the risk factors that are significantly related to PONV. The objective variables were classified into three categories: no PONV, early PONV (initial onset time: 0-2 h after anesthesia), and late PONV (initial onset time: 2-24 h after anesthesia). The explanatory variables included relevant risk factors for PONV, as considered in previous studies. Results Total intravenous anesthesia with propofol was a significant depressant factor for early PONV (adjusted odds ratio [aOR] = 0.340, 95% confidence interval [CI] = 0.209-0.555) and late PONV (aOR = 0.535, 95% CI = 0.352-0.814). The administration of a combination of intraoperative antiemetics (vs. no administration) significantly reduced the risk of early PONV (aOR = 0.464, 95% CI = 0.230-0.961). Female sex and young age were significant risk factors for late PONV (aOR = 1.492, 95% CI = 1.170-1.925 and unit aOR = 1.033, 95% CI = 1.010-1.057, respectively). Conclusion We identified factors that are significantly related to PONV based on the initial onset time after orthognathic surgery. Total intravenous anesthesia with propofol significantly reduced the risk of PONV not only in the early period (0-2 h after anesthesia) but also in the late period (2-24 h after anesthesia).

Abstract
Abstract
Introduction
The electrical pulmonary vein (PV) isolation has been established as a curative therapy for paroxysmal atrial fibrillation (AF). Arctic Front™cryoballoon has been used worldwide for AF cryoablation. Recently, a new cryoballoon, POLARxTM CRYOABLATION system have been introduced, of which material of the balloon is softer and the N2O gas flow rate is higher.
Purpose
The aim was to investigate the procedural parameter and efficacy of POLARx comparing with Arctic Front.
Methods
This retrospective single center study included 101 consecutive patients who underwent paroxysmal AF ablation using cryoballoon at Keio University hospital from April 2021 to March 2022. The procedural data including the cryoballoon temperature and the number and duration of cryoablation were compared between POLARx (POLARx group) and ARCTIC FRONT ADVANCE PRO (AFA group). After the cryoablation, we added the radiofrequency application in order to maximize the isolated area when the voltage was remained inside PV (Figure 1). The necessities of the additional radiofrequency applications were also compared.
Results
In the present study, 64 patients in AFA group and 37 patients in POLARx group were analyzed. POLARx group included younger population and less females (62.8±9.9 vs 67.5±9.4 year of age, P=0.02; 13.5 vs 32.8%, P=0.04). There was no significant difference in comorbidities and examination data such as left atrium diameter or brain natriuretic peptide level. The minimal cryoballoon temperatures reached in POLARx group were lower than AFA group (−59.3±6.2 vs −47.7±7.5°C, P<0.01). No difference was found in the total number and duration of cryoablation and the time to isolate PV (6.1±2.1 vs 5.9±1.6, P=0.69; 790.2±256.1 vs 776.1±235.0 sec, P=0.69; 41.8±21.3 vs 47.1±29.6 sec, P=0.44, respectively). With regard to individual PVs, the total number and duration were tended to be larger at right superior PV in POLARx group (1.9±1.1 vs 1.4±0.7, P=0.01; 231.8±123.8 vs 193.2±83.0 sec, P=0.07), while there was no significant difference at the other PVs. The rate of successful PV isolation by a single cryo-application was not different between AFA and POLARx group (54.3 vs 61.4%, P=0.17). The additional radiofrequency applications were more frequent in AFA group (14.8 vs. 4.9%, P=0.003). There was a significant difference at right inferior PV (32.8 vs 8.1%, P=0.01), while not at left superior PV, left inferior PV and right superior PV (9.4 vs 2.9%, P=0.42; 9.4 vs 5.7%, P=0.71; 7.8 vs 2.7%, P=0.41). Phrenic nerve injury was occurred 1 case in both group and esophageal ulcer was occurred in 1 case in AFA group. No other complication including cardiac tamponade was occurred.
Conclusion
The total number and duration of cryoablation were not significantly different between AFA and POLARx group, except for right superior PV. There was an advantage in largely isolating right inferior PV in POLARx group comparing with AFA group.

Abstract
Abstract
We have synthesized an analog of aristolochic acid (AA) with potent growth inhibitory activity in various human cancer cell lines and report here on mechanistic studies of this potential therapeutic. AA is a natural product and the main active principle of Aristolochia plants, a known source of antitumor agents. In 1964 due to nephrotoxicity, drug development efforts with AA were terminated following Phase I clinical trial in patients with terminal cancer of different origin. Structure activity studies of AA species allowed us to select a structural analog of AA (RJ-34) that lacks the determinants responsible for the renal toxicity and carcinogenicity of the parent compound. Building further on our experience with AA molecules, we developed a synthetic approach that affords efficient high-yield synthesis of RJ-34. Its structure and purity has been confirmed by high-performance liquid chromatography, liquid chromatography coupled with two-stage mass spectrometry and high resolution nucleic magnetic resonance. Sulforhodamine B assay revealed that RJ-34 has growth inhibitory activity in A549 and HCT-15 human cancer cell lines comparable to or stronger than that of paclitaxel or topotecan. At five nanomolar, RJ-34 inhibited DNA synthesis and cut the growth of A549 cells by 50%, leading to cell cycle arrest in G1/M and G2/S, with apparent apoptosis at concentrations greater than 200 nanomolar. Notably, protein synthesis in cultured cells, as evaluated by puromycin labelling, remained unaffected. RJ-34 was screened against the NCI-60 cell line panel - encompassing sixty human cancer cell lines from various tissues - providing clues to its mechanisms of action; namely, that RJ-34 acts through inhibition of DNA topoisomerases I and II and/or DNA intercalation. Follow-up studies using purified calf Topo I and human Topo II alpha and various plasmid substrates confirmed the role of RJ-34 as a DNA intercalator and human Topoisomerase II alpha poison. The pattern of activity of RJ-34 in the NCI-60 panel was distinct from that of AA and aristolactam - another related compound - suggesting that RJ-34 acts by mechanisms distinct from AA. In summary, RJ-34— a non-nephrotoxic analog of aristolochic acid— has a potent growth inhibitory activity in various human cancer cell lines with a mechanism of action different from the parent AA. Moving forward, pre-clinical pharmacokinetics, safety and efficacy studies are necessary to establish the potential of RJ-34 for development as an anticancer therapeutic.

Abstract
OBJECTIVE The incidence of postoperative nausea and vomiting (PONV) after general anesthesia with total intravenous anesthesia (TIVA) was reported to be significantly lower than with volatile inhalational agents (13.3% vs 25%). However, no investigation of PONV risk factors associated with TIVA has ever been reported. This cross-sectional retrospective study aimed to investigate whether known risk factors influenced PONV in intubated general anesthetics utilizing TIVA for dental or oral and maxillofacial surgery. METHODS Subjects were 761 patients who underwent dental or oral and maxillofacial surgery under TIVA with propofol, fentanyl, and remifentanil. Univariate and multivariable logistic regression analyses were performed using PONV (within 24 hours) as the dependent variable and previously reported risk factors as independent variables. RESULTS Age (odds ratio [OR]: 1.020 per year decrease; 95% confidence interval [CI]: 1.0002-1.0418; P = .047) and female sex (OR: 2.73; 95% CI: 1.60-4.84; P < .001) were positively associated with PONV. Sagittal split ramus osteotomy (SSRO) (OR: 2.28; 95% CI: 1.21-4.33; P = .011) and bimaxillary osteotomy (OR: 5.69; 95% CI: 2.09-15.99; P < .001) were more likely to be associated with PONV than operations that were neither bimaxillary osteotomy nor SSRO. Late PONV (2-24 hours) had an ∼2.7 times higher incidence than early PONV (0-2 hours). CONCLUSION These findings suggest further PONV countermeasures, aside from TIVA with propofol and prophylactic antiemetics for orthognathic surgeries especially bimaxillary osteotomy, are needed.

Abstract
PURPOSE The purpose of the study was to explore whether a developmental test provides enough information to estimate a child's functional independence. The strength of the relationship between developmental level and functional independence of different skills was investigated. METHODS The participants were 397 children (age 0-7 years) who were referred to NCCHD for suspected developmental delay. The participants' developmental level was measured with the Kyoto Scale of Psychological Development (KSPD) and their functional independence was assessed through a Japanese version of the WeeFIM II®. To calculate the strengths of the relationship between developmental age (DA) in different domains of the KSPD and WeeFIM II item scores, partial correlation analyses were conducted, controlling for chronological age. RESULTS Partial correlation coefficients between the score of each of the 18 WeeFIM II items and each of the three KSPD domain DAs (controlling chronological age) fell in the ranges of r = 0.169-0.581 (Posture-Motor; P-M), r = 0.377-0.627 (Cognitive-Adaptive; C-A), and r = 0.332-0.655 (Language-Social; L-S). When the participants were divided into three age groups, the correlations ranged from -0.095 to 0.552 for the youngest group (mean age = 14.21 months), from 0.283 to 0.653 for the middle group (mean age = 32.98 months), and from 0.345-0.692 for the oldest group (mean age = 57.48 months), depending on the combinations of the WeeFIM II items/developmental domains of the KSPD. The results indicated that for most of the daily living skills, its functional independence was only partially explained by the scores of a developmental test, once chronological age was controlled. CONCLUSION This study showed the limitation of a developmental test as a tool to measure the functional independence of children and the necessity of using an independent tool, such as WeeFIM II, to evaluate the level of required support for each daily living skill.

Abstract
Angiotensin receptor blockers (ARBs) are widely used to treat hypertension, but severe refractory hypotension during general anesthesia is a well-known complication associated with the continuation of ARBs during the perioperative period. It has therefore been recommended that ARBs be withheld for 24 hours before induction of general anesthesia. However, impaired renal function affects the pharmacokinetics of each ARB differently. The half-life of azilsartan is prolonged in accordance with the degree of renal impairment. Herein, we describe a patient with chronic kidney disease grade 3B who experienced severe refractory hypotension after induction of general anesthesia requiring administration of dopamine following inadequate responses to ephedrine and phenylephrine despite a 24-hour azilsartan washout period. When the same patient underwent general anesthesia for a subsequent surgery, azilsartan was withheld for 48 hours before induction, resulting in mild intraoperative hypotension that responded adequately to phenylephrine. Severe refractory hypotension during general anesthesia cannot always be avoided by holding azilsartan for 24 hours in patients with significant renal impairment. Therefore, a longer washout period may be preferable for patients regularly taking azilsartan who also have concurrent substantial renal impairment.

Abstract
It remains unknown whether the histology of vascular invasion during secondary ossification of epiphyseal cartilage is the same as that seen in primary ossification; we examined the initial processes of vascular invasion of secondary ossification in the murine femora. Many endomucin-immunoreactive blood vessels gathered at the central region of the articular surface, and buds of soft tissue, including glomerular loops of endomucin-immunoreactive blood vessels and TNALPase- immunopositive osteoblastic cells accompanied by TRAP-positive osteoclasts, had begun to invade the epiphyseal cartilage. The invading soft tissues formed cartilage canals displaying MMP9 immunoreactivity in the tip region, and cartilaginous collagen fibrils were not visible in the vicinity of the vascular wall of the blood vessels. Thus, the histological profile marked by invading glomerular vasculature and the erosion of the cartilage matrix near the vascular walls during secondary ossification differs from that seen during primary ossification.

Abstract
Metal-organic frameworks (MOFs), which are self-assemblies of metal ions and organic ligands, provide a tunable platform to search a new state of matter. A two-dimensional (2D) perfect kagome lattice, whose geometrical frustration is a key to realizing quantum spin liquids, has been formed in the π - d conjugated 2D MOF [Cu3(C6S6)] n (Cu-BHT). The recent discovery of its superconductivity with a critical temperature T c of 0.25 kelvin raises fundamental questions about the nature of electron pairing. Here, we show that Cu-BHT is a strongly correlated unconventional superconductor with extremely low superfluid density. A nonexponential temperature dependence of superfluid density is observed, indicating the possible presence of superconducting gap nodes. The magnitude of superfluid density is much smaller than those in conventional superconductors and follows the Uemura's relation of strongly correlated superconductors. These results imply that the unconventional superconductivity in Cu-BHT originates from electron correlations related to spin fluctuations of kagome lattice.

Abstract
This study aimed to compare cerebral oxyhemoglobin (O2Hb) levels during incremental exercise by cycling vs. arm cranking in 12 healthy adult men aged 20.8 ± 0.2 years old. O2Hb was measured by near-infrared spectroscopy. Regions of interest included the left and right prefrontal cortices (LtPFC and RtPFC, respectively), the left and right premotor cortices (LtPMC and RtPMC, respectively), and the supplementary motor area (SMA) bilaterally. After 4 min of rest, 4 min of warm-up was performed by using ergometer followed by incremental exercise (increasing work rate by 5 W/min for arm cranking and 20 W/min for cycling exercise). All values were averaged every tenth of the participant's exercise time period from beginning of incremental exercise to end point. At the middle exercise intensity (50% exercise time), the averaged O2Hb values obtained at all regions of interest seemed to be higher during arm cranking exercise as compared to cycling; however, there were no significant differences between two types of exercise. At the end point of incremental exercise (100% exercise time), the O2Hb obtained at all regions of interest was significantly higher during arm cranking exercise compared to cycling (LtPFC 0.081 ± 0.019 vs. -0.001 ± 0.013 mM·cm, RtPFC 0.076 ± 0.021 vs. 0.018 ± 0.015 mM·cm, SMA 0.012 ± 0.040 vs. 0.040 ± 0.016 mM·cm; arm cranking vs. cycling; p < 0.05, respectively). We conclude that exercise-induced cerebral oxygenation is greater with arm cranking than with leg cycling.

Abstract
The Japan Atomic Energy Agency (JAEA) started the Research and Development (R&D) to improve nuclear prediction techniques for High Temperature Gas-cooled Reactors (HTGRs). The objectives are to introduce a generalized bias factor method to avoid full mock-up experiment for the first commercial HTGR and to introduce reactor noise analysis to High Temperature Engineering Test Reactor (HTTR) experiment to observe sub-criticality. To achieve the objectives, the reactor core of graphite-moderation system named B7/4”G2/8”p8EUNU+3/8”p38EU(1) was newly composed in the B-rack of Kyoto University Critical Assembly (KUCA). The core is composed of the fuel assembly, driver fuel assembly, graphite reflector, and polyethylene reflector. The fuel assembly is composed of enriched uranium plate, natural uranium plate and graphite plates to realize the average fuel enrichment of HTTR and it’s spectrum. However, driver fuel assembly is necessary to achieve the criticality with the small-sized core. The core plays a role of the reference core of the bias factor method, and the reactor noise was measured to develop the noise analysis scheme. In this study, the overview of the criticality experiments is reported. The reactor configuration with graphite moderation system is rare case in the KUCA experiments, and this experiment is expected to contribute not only for an HTGR development but also for other types of a reactor in the graphite moderation system such as a molten salt reactor development.

Abstract
BACKGROUND Aristolochic acids (AA) and arsenic are chemical carcinogens associated with urothelial carcinogenesis. Here we investigate the combined effects of AA and arsenic toward the risk of developing upper tract urothelial carcinoma (UTUC). METHODS Hospital-based (n = 89) and population-based (2,921 cases and 11,684 controls) Taiwanese UTUC cohorts were used to investigate the association between exposure to AA and/or arsenic and the risk of developing UTUC. In the hospital cohort, AA exposure was evaluated by measuring aristolactam-DNA adducts in the renal cortex and by identifying A>T TP53 mutations in tumors. In the population cohort, AA exposure was determined from prescription health insurance records. Arsenic levels were graded from 0 to 3 based on concentrations in well water and the presence of arseniasis-related diseases. RESULTS In the hospital cohort, 43, 26, and 20 patients resided in grade 0, 1+2, and 3 arseniasis-endemic areas, respectively. Aristolactam-DNA adducts were present in >90% of these patients, indicating widespread AA exposure. A>T mutations in TP53 were detected in 28%, 44%, and 22% of patients residing in grade 0, 1+2, and 3 arseniasis-endemic areas, respectively. Population studies revealed that individuals who consumed more AA-containing herbs had a higher risk of developing UTUC in both arseniasis-endemic and nonendemic areas. Logistic regression showed an additive effect of AA and arsenic exposure on the risk of developing UTUC. CONCLUSIONS Exposure to both AA and arsenic acts additively to increase the UTUC risk in Taiwan. IMPACT This is the first study to investigate the combined effect of AA and arsenic exposure on UTUC.

Abstract
Abstract
Background
Whether optical frequency domain imaging (OFDI) images can realize pathological diagnosis of coronary atherosclerotic plaques, and whether its diagnostic accuracy of lesion types varies depending on the personal experience of the clinician caring for coronary intervention have not been elucidated.
Purpose
This study investigated the interobserver variability in characterizing atherosclerotic plaque types by OFDI for multiple OFDI observers with levels of different experience.
Methods
Three-hundred-thirty-three histological cross-sections from 21 autopsy hearts were co-registered with the corresponding OFDI images. Histological cross-sections were classified into the following 7 lesion types according to the modified AHA atherosclerosis classification by a single experienced pathologist blinded for OCT findings: adaptive intimal thickening (AIT), intimal xanthoma (IX), pathological intimal thickening (PIT), fibrous cap atheroma (FA), fibrocalcific plaque (FC), calcified nodule (CN), and healed erosion/rupture (HER). The five OFDI observers, unaware of the histological diagnosis, provided a single diagnosis for each corresponding OFDI image. The OFDI observer 1 was an expert interventional cardiologist with sufficient experience in OFDI imaging, followed by the OFDI observer 2, 3, and 4 as middle career interventional cardiologists who had completed training ten, seven, and four years. The OFDI observer 5 was a young career interventional cardiologist. The diagnostic accuracy of lesion types for each OFDI observer was determined taking histology as a gold standard.
Results
On histological analysis, 13% of histological cross-sections were diagnosed as AIT, 5% as IX, 23% as PIT, 25% as FA, 27% as FC, 2% as CN, and 5% as HER. The overall agreement between OFDI diagnosis and histopathologic diagnosis for OFDI observer 1 to 5 was 77%, 62%, 61%, 56%, and 46% (k values of 0.71, 0.54, 0.54, 0.45, and 0.33), respectively. Although the performance for characterizing AIT and FC was excellent and comparable among all OFDI observers, the sensitivity and positive predictive value for characterizing IX, PIT and FA varied depending on the OFDI observers' years of experience (Table). The main causes of false-positive or -negative diagnosis of FA were IX and PIT for all OFDI observers.
Conclusion
The diagnostic accuracy of atherosclerotic tissue properties from OFDI images correlated with the observers' years of experience, subspecialty training in coronary imaging, which suggests that the interpretation of OFDI images requires expertise and can be challenging to a less experienced reader.

Abstract
Abstract
Background
Cryoballoon ablation (CBA) is a widely used procedure for atrial fibrillation (AF). However, the anatomical change of pulmonary veins (PVs) and the risk factors of PV stenosis is less clear. We aimed to decipher the prevalence and the predictive factors for PV stenosis after CBA.
Methods
We analyzed the data of 320 PVs from 80 patients who underwent CBA for AF (age: 62±10 years, 59 males, 75 paroxysmal AF). All patients underwent pre- and post-procedural cardiac computed tomography (mean 6.7±3.3 months after ablation). We defined the PV stenosis when the cross sectional area of PV was less than 50% compared with that of PV before the CBA.
Results
The average cross sectional PV area decreased significantly after CBA (pre- vs. post-CBA; 2.4±1.0cm2 vs. 2.3±1.1cm2, P<0.001), whereas the volume of left atrium (LA) also decreased significantly (pre- vs. post-CBA; 75.0±23.2cm3 vs. 70.7±21.9cm3, P<0.001). There was a weak but significant correlation between the reduction rate of PV area and that of LA volume (Pearson's correlation coefficient 0.411, p<0.001). Only 6 PV stenosis were revealed, in which area reduction of more than 75% and 50–75% were observed in 2 PVs and 4 PVs, respectively. The incidence of PV stenosis was greater in female (male vs. female; 0.8% vs. 4.8%, P=0.043) and tend to be frequent in left PVs (left PVs vs. right PVs; 3.1% vs. 0.6%: P=0.107). Moreover, patients who developed PV stenosis tended to have lower weight and shorter height (PV stenosis group vs. non-PV stenosis group; 58.2±12.4kg vs. 67.7±13.0kg: P=0.078, 161.2±9.1cm vs. 167.2±8.8cm: P=0.094). There were no significant differences in the number of freezing, minimum temperature and total freezing time between PV stenosis group and non-PV stenosis group.
Conclusions
The ostial PV area decreased significantly but little after CBA, possibly due to LA reverse remodeling. The PV stenosis was more common in women and tend to be frequent in left PVs, lower weight, and shorter height patients, though severe stenosis after CBA was not observed in this study.

Abstract
Background Recently, intravenous magnesium therapy has been used for the treatment of ventricular arrhythmias, but data to establish a causal link between the electrophysiological properties and the antiarrhythmic actions are lacking. Methods and Results The acute antiarrhythmic effect of magnesium sulfate was assessed using epinephrine-, digitalis-, and coronary ligation-induced canine ventricular arrhythmia models. The intravenous administration of magnesium sulfate (100 mg/kg) reduced the incidence of the ventricular arrhythmias of all models. The antiarrhythmic effect on the epinephrine-induced arrhythmia was potent and long-lasting, while those on the other arrhythmia models were weak and transient. The direct cardiovascular effects were assessed using the canine isolated, blood-perfused sinus node, papillary muscle, and atrioventricular node preparations. The intracoronary administration of magnesium sulfate (0.1–30 mg) suppressed sinoatrial automaticity and ventricular contraction, while it increased atrio-His and His-ventricular conduction time, coronary blood flow, and the duration of monophasic action potential in a dose-dependent manner. The effects on His-ventricular conduction and monophasic action potential duration were less potent compared with the other cardiovascular effects. Conclusion These results suggest that magnesium sulfate possesses multiple electrophysiological properties and that the effects related to the calcium channel inhibition may be the most relevant for the antiarrhythmic actions.

Abstract
AIM To elucidate mechanisms by which mineral trioxide aggregate (MTA) suppresses pro-inflammatory cytokine mRNA expression in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. METHODOLOGY Mineral trioxide aggregate extracts were prepared by immersing set ProRoot MTA in culture medium. RAW264.7 cells were cultured in the presence of LPS and MTA extracts. mRNA expression levels of interleukin (IL)-1α, IL-6, early growth response 2 (Egr2), suppressor of cytokine signalling 3 (Socs3) and IL-10 were quantified with reverse transcription-quantitative polymerase chain reaction. Phosphorylation of nuclear factor-kappa B (NF-κB) p65 in RAW264.7 cells was analysed by Western blotting. Intracellular calcium imaging was performed with Fluo-4 AM. The activity of nuclear factor of activated T cells (NFAT) was determined by luciferase assays. Enforced expression and silencing of Egr2 in RAW264.7 cells were carried out using an expression vector and specific RNAi, respectively. In vivo kinetics of Egr2+ cells in MTA-treated rat molar pulp tissues were examined using immunohistochemistry. Data were analysed by one-way analysis of variance, followed by the Tukey-Kramer test (P < 0.05). RESULTS Exposure to MTA extracts resulted in reduced mRNA expression levels of IL-1α and IL-6, as well as reduced expression of phosphorylated NF-κB, in LPS-stimulated RAW264.7 cells. Exposure to MTA extracts induced Ca2+ influx, which was blocked by NPS2143, an antagonist of calcium-sensing receptor (CaSR); Ca2+ influx then triggered activation of calcineurin/NFAT signalling and enhanced mRNA expression of Egr2. Enforced expression of Egr2 in RAW264.7 cells promoted the expression of both IL-10 and Socs3. In vivo application of MTA onto rat molar pulp tissue resulted in the appearance of Egr2-expressing cells that coexpressed CD163, a typical M2 macrophage marker. CONCLUSIONS Mineral trioxide aggregate extracts induced downregulation of IL-1α and IL-6 in LPS-stimulated RAW264.7 cells via CaSR-induced activation of calcineurin/NFAT/Egr2 signalling and subsequent upregulation of IL-10 and Socs3.

Abstract
Substance abuse disorder continues to have devastating consequences for individuals and society and current therapies are not sufficient to provide the magnitude of medical impact required. Although some evidence suggests the use of ketamine in treating various substance use related- symptoms, its adverse event profile including dissociation, dysphoria, and abuse liability limit its potential as a therapy. Here, we outline experiments to test our hypothesis that (R)-ketamine can both alleviate withdrawal symptoms and produce effects that help sustain abstinence. In morphine-dependent rats, (R)-ketamine alleviated naloxone-precipitated withdrawal signs. (R)-ketamine also blocked morphine-induced place preference in mice without inducing place preference on its own. We also evaluated whether (R)-ketamine would induce anhedonia, a counter-indicated effect for a drug abuse treatment agent. S-(+)- but not R-(-)-ketamine produced anhedonia-like responses in rats that electrically self-stimulated the medial forebrain bundle (ICSS). However, time-course studies of ICSS are needed to fully appreciate these differences. These data begin to support the claim that (R)-ketamine will dampen withdrawal symptoms and drug liking, factors known to contribute to the cycle of drug addiction. In addition, these data suggest that (R)-ketamine would not produce negative mood or anhedonia that could interfere with treatment. It is suggested that continued investigation of (R)-ketamine as a novel therapeutic for substance abuse disorder be given consideration by the preclinical and clinical research communities. This suggestion is further encouraged by a recent report on the efficacy of (R)-ketamine in treatment-resistant depressed patients at a dose with little measurable dissociative side-effects.

Abstract
The (6-4) pyrimidine-pyrimidone photoproduct [(6-4)PP] is a major DNA lesion induced by ultraviolet radiation. (6-4)PP induces complex mutations opposite its downstream bases, in addition to opposite 3' or 5' base, as has been observed through a site-specific translesion DNA synthesis (TLS) assay. The mechanism by which these mutations occur is not well understood. To elucidate the mechanisms underlying mutagenesis induced by (6-4)PP, we performed an intracellular TLS assay using a replicative vector with site-specific T(thymidine)-T (6-4)PP. Rev3-/-p53-/- mouse embryonic fibroblast (MEF) cells (defective in Polζ) were almost completely defective in bypassing T-T (6-4)PP, whereas both Rev1-/- and Polh-/-Poli-/-Polk-/- MEF cells (defective in Polη, Polι, and Polκ) presented bypassing activity comparable to that of wild-type cells, indicating that Y-family TLS polymerases are dispensable for bypassing activity, whereas Polζ plays an essential role, probably at the extension step. Among all cells tested, misincorporation occurred most frequently just beyond the lesion (position +1), indicating that the Polζ-dependent extension step is crucial for (6-4)PP-induced mutagenesis. We then examined the effects of sequence context on T-T (6-4)PP bypass using a series of T-T (6-4)PP templates with different sequences at position +1 or -1 to the lesion, and found that the dependency of T-T (6-4)PP bypass on Polζ is not sequence specific. However, the misincorporation frequency at position +1 differed significantly among these templates. The misincorporation of A at position +1 occurred frequently when a purine base was located at position -1. These results indicate that Polζ-dependent extension plays a major role in inducing base substitutions in (6-4)PP-induced mutagenesis, and its fidelity is affected by sequence context surrounding a lesion.

Abstract
The present study aimed to develop and validate a model for predicting the need for emergency front-of neck airway (eFONA) procedures among trauma patients. This was a multicentre retrospective cohort study using data from the Japan Trauma Data Bank between January 2004 and December 2017. Only adult trauma patients were included. The cohort was divided into development and validation cohorts. A simple scoring system was developed to predict the necessity for emergency front-of neck airway procedures in the development cohort using a logistic regression model. The external validity and diagnostic ability of the scoring system was assessed in the validation cohort. In total, 198,182 out of 294,274 patients were included; emergency front-of-neck airway occurred in 467 patients (0.24%) they were divided into development (n = 100,120 with 0.22% undergoing emergency front-of neck airway) and validation (n = 98,062 with 0.25% undergoing emergency front-of neck airway) cohorts. The 'eFONA' prediction scoring system was developed in the development cohort, with a score of +1 for each of the following: Eye opening (no eye opening in response to any stimuli); Fall from height or motor bike; Oral-maxillofacial injury; Neck tracheal injury; and Airway management by paramedics. In the validation cohort, the C-statistic of the scoring system was 0.820. Setting the cut-off value at one for rule-out, the sensitivity and negative likelihood ratios were 0.86 and 0.22, respectively. Setting the cut-off value at two for rule-in, the specificity and positive likelihood ratios were 0.91 and 6.6, respectively. The present scoring system may assist in predicting the need for emergency front-of neck airway procedures among the general trauma population.

Abstract
BACKGROUND This study assessed the psychometric profile of 10 questionnaires (every 6 months, from 6 to 60 months) from the Japanese translation of the Ages and Stages Questionnaires, third edition (J-ASQ-3). METHODS Data from 439 children in a birth cohort were used to identify the J-ASQ-3 score distribution, establish cut-off scores, and calculate the instrument's internal consistency. Data were also collected from 491 outpatients to examine J-ASQ-3 test-retest reliability and concurrent validity, which was examined using the Kyoto Scale of Psychological Development (KSPD) and the Japanese version of the Denver Developmental Screening Test II (J-Denver II). Both the original and the alternative screening criteria of the ASQ-3 were used (failure in at least one and at least two domains, respectively). RESULTS Cronbach's alpha for each J-ASQ-3 subscale on each questionnaire ranged from 0.45 to 0.89. Test-retest reliability was >0.75 for the subscales on almost all questionnaires. Concurrent validity was also adequate. In comparison with the screening results of the KSPD, the overall sensitivity and specificity were 96.0% and 48.8%, respectively, when the ASQ-3 original criterion was used, and 92.1% and 74.9%, respectively, when the alternative criterion was used. In comparison with the screening results of the J-Denver II, the overall sensitivity and specificity were 75.6% and 74.7%, respectively, when the ASQ-3 original criterion was used, and 56.3% and 93.0%, respectively, when the alternative criterion was used. CONCLUSIONS This study quantified the psychometric profiles of the Japanese translations of 10 ASQ-3 questionnaires. We demonstrated the validity of the J-ASQ-3 and determined new cut-off scores. Further studies with larger samples from a greater range of locations are required to clarify the suitability of this tool for all Japanese children.

Abstract
Abstract
Background
Recent guidelines have stated that reduced left ventricular ejection fraction (LVEF) is the gold standard marker for identifying patients at risk for cardiac mortality. Although reduced LVEF identifies patients at an increased risk of cardiac arrest, sudden cardiac deaths (SCDs) occur considerably more often in patients with relatively preserved LVEF. Current guidelines on SCD risk stratification do not adequately cover this general population pool. Several noninvasive electrocardiographic (ECG) risk stratifiers that reflect depolarization abnormality, repolarization abnormality, and autonomic imbalance have been evaluated so far. With current therapeutic advances using new medicines or devices, an LVEF is often preserved in patients with structural heart disease (SHD). However, the usefulness of noninvasive ECG markers for risk stratification in such a patient population has not yet been elucidated.
Purpose
This study aimed to assess clinical indices and ECG markers based on 24-hour Holter ECG recordings for predicting cardiac mortality in patients with SHD who have left ventricular dysfunction (LVD) but relatively preserved LVEF.
Methods
In total, 1,829 patients were enrolled into the Japanese Multicenter Observational Prospective Study (JANIES study). In this study, we analyzed data of 719 patients (569 men, age 64±13 years) with SHD including mainly ischemic heart disease (65.8%). As ECG markers based on 24-hour Holter recordings, nonsustained ventricular tachycardia (NSVT), ventricular late potentials, and heart rate turbulence (HRT) were assessed. The primary endpoint was all-cause mortality, and the secondary endpoint was fatal arrhythmic events.
Results
During a mean follow-up of 21±11 months, all-cause mortality was eventually observed in 39 patients (5.4%). Among those patients, 32 patients (82%) suffered from cardiac causes such as heart failure and arrhythmia. Multivariate Cox regression analysis showed that after adjustment for age and LVEF, documented NSVT (hazard ratio=2.82, 95% confidence interval [CI]: 1.38–5.76, P=0.005) and abnormal HRT (hazard ratio=2.31, 95% CI: 1.15–4.65, P=0.02) were significantly associated with the primary endpoint. These two ECG markers also had significant predictive values with the secondary endpoint. The combined assessment documented NSVT and abnormal HRT improved predictive accuracy.
Conclusion
This study demonstrated that combined assessment of documented NSVT and abnormal HRT based on 24-hour Holter ECG recordings are recommended for predicting future serious events in SHD patients who have relatively preserved LVEF.
