Abstract
In plants, many invading microbial pathogens are recognized by cell-surface pattern recognition receptors, which induce defense responses. Here, we show that the ceramide Phytophthora infestans-ceramide D (Pi-Cer D) from the plant pathogenic oomycete P. infestans triggers defense responses in Arabidopsis. Pi-Cer D is cleaved by an Arabidopsis apoplastic ceramidase, NEUTRAL CERAMIDASE 2 (NCER2), and the resulting 9-methyl-branched sphingoid base is recognized by a plasma membrane lectin receptor-like kinase, RESISTANT TO DFPM-INHIBITION OF ABSCISIC ACID SIGNALING 2 (RDA2). 9-Methyl-branched sphingoid base is specific to microbes and induces plant immune responses by physically interacting with RDA2. Loss of RDA2 or NCER2 function compromised Arabidopsis resistance against an oomycete pathogen. Thus, we elucidated the recognition mechanisms of pathogen-derived lipid molecules in plants.

Abstract
Abstract
Purpose
We aimed to explore the association of blood pressure (BP) classification using the 2017 American College of Cardiology/ American Heart Association Guideline and the prevalence of hypertensive retinopathy using a nationwide epidemiological database.
Methods
This study is a retrospective observational cross-sectional analysis using the health claims database of the JMDC between 2005 and 2020. We analyzed 280,599 participants who did not take anti-hypertensive medications. Each participant was categorized as having normal BP (systolic BP [SBP] <120 mm Hg and diastolic BP [DBP] <80 mm Hg; n=159,524); elevated BP (SBP 120–129 mm Hg and DBP <80 mm Hg; n=35,603); stage 1 hypertension (SBP 130–139 mm Hg or DBP 80–89 mm Hg; n=54,795); or stage 2 hypertension (SBP ≥140 mm Hg or DBP ≥90 mm Hg; n=30,677). Retinal photography at health check-up was classified as normal, grade 1, grade 2, grade 3, or grade 4 according to the Keith-Wagener-Barker system.
Results
Median (interquartile range) age was 46 (40–53) years, and 50.4% were men. Hypertensive retinopathy which was defined as ≥ Keith-Wagener-Barker system grade 1, was observed in 16,836 participants (6.0%). Multivariable logistic regression analysis showed that, compared with normal BP, elevated BP (odds ratio [OR] 1.30, 95% confidence interval [CI] 1.23–1.38), stage 1 hypertension (OR 1.71, 95% CI 1.64–1.79), and stage 2 hypertension (OR 4.10, 95% CI 3.93–4.28) were associated with higher prevalence of hypertensive retinopathy. Even among 92,121 participants without obesity, high waist circumference, diabetes mellitus, dyslipidemia, cigarette smoking, and alcohol drinking, multivariable logistic regression analysis showed that, compared with normal BP, elevated BP (odds ratio 1.34, 95% CI 1.19–1.51), stage 1 hypertension (OR 1.79, 95% CI 1.61–1.98), and stage 2 hypertension (OR 4.42, 95% CI 4.00–4.92) were associated with higher prevalence of hypertensive retinopathy. The association between BP category and hypertensive retinopathy was observed in all subgroups stratified by age or sex.
Conclusion
Our investigation showed that the prevalence of hypertensive retinopathy increased with the blood pressure category, suggesting that atherosclerotic change could start even in elevated BP and stage 1 hypertension.

Abstract
AIMS To elucidate (i) the challenges and constraints in the development and implementation of the regulatory framework for nursing professionals in Cambodia and (ii) the specific strategies adopted to address the challenges experienced in Cambodia. INTRODUCTION The health workforce will be critical to achieving the health-related and wider Sustainable Development Goals in the years up to 2030. BACKGROUND In 2006, the countries of the Association of Southeast Asian Nations signed a Mutual Recognition Arrangement in relation to nursing services in the region with the main aim of facilitating the mobility of nursing professionals between countries. To ensure the competency of the health workforce and the quality and safety of health services, member states are required to establish an appropriate regulatory framework. METHODS This is a qualitative descriptive study. Eighteen key informant interviews were conducted in Cambodia in 2018. Walt and Gilson's policy analysis model was applied to organize and synthesize the data. FINDINGS Major challenges were identified such as conceptual and cultural issues, limited capacity of Cambodian stakeholders and an unstandardized system with limited coordination. DISCUSSION In Cambodia, the nursing regulatory environment has expanded greatly over the last decade. Strategies adopted were 'political leadership', optimal utilization of 'outsider's capacity', strengthening 'insider's capacity', and 'dedicated consultation and collaboration and consensus building' involving all players. IMPLICATIONS FOR NURSING AND HEALTH POLICIES Policymakers in similar resource-limited countries could apply and adapt similar strategic efforts when formulating and implementing health policies, legislation and regulations. 'Outsiders', in this case, represented by development partners can play a vital role in the process, but should not be leading the charge. They should be aligned with national priority to support recipient countries. It is imperative for these countries and development partners to invest in increasing the quantity and quality of nursing leaders who can develop and advance regulatory functions.

Abstract
Ferroaxial materials that exhibit spontaneous ordering of a rotational structural distortion with an axial vector symmetry have gained growing interest, motivated by recent extensive studies on ferroic materials. As in conventional ferroics (e.g., ferroelectrics and ferromagnetics), domain states will be present in the ferroaxial materials. However, the observation of ferroaxial domains is non-trivial due to the nature of the order parameter, which is invariant under both time-reversal and space-inversion operations. Here we propose that NiTiO3 is an order-disorder type ferroaxial material, and spatially resolve its ferroaxial domains by using linear electrogyration effect: optical rotation in proportion to an applied electric field. To detect small signals of electrogyration (order of 10−5 deg V−1), we adopt a recently developed difference image-sensing technique. Furthermore, the ferroaxial domains are confirmed on nano-scale spatial resolution with a combined use of scanning transmission electron microscopy and convergent-beam electron diffraction. Our success of the domain visualization will promote the study of ferroaxial materials as a new ferroic state of matter. The presence of ferroaxial domain states is recently experimentally demonstrated by a nonlinear optical technique, which lacks high spatial resolution to visualize ferroaxial domains. Here, the authors visualize spatial distributions of ferroaxial domains in NiTiO3 showing an order-disorder type ferroaxial transition.

Abstract
Abstract
Objectives
We assessed clinical outcomes after percutaneous coronary intervention (PCI) for unprotected left main (ULM) using current generation drug eluting stents (cDES) in hemodialysis (HD) patients compared to general populations.
Methods
We identified 1269 consecutive patients who underwent PCI for ULM distal bifurcation lesions. Of them, 563 patients were treated with cDES (512 non HD and 51 HD patients). The primary endpoint was target lesion failure (TLF) at 3 years, defined as a composite of cardiac death, target lesion revascularization (TLR) and myocardial infarction (MI).
Results
HD group was more likely to have diabetes mellitus (70.0% vs. 45.8%, p=0.002), peripheral artery disease (56.0% vs. 14.9%, p<0.001), and lower ejection fraction (52.6% vs. 56.3%, p=0.026). The rate of TLF at 3 years was significantly higher in the HD group (adjusted Hazard ratio [HR] 2.59; 95% confidence interval [CI], 1.54–4.37; p<0.001). Cardiac mortality was significantly higher in the HD group (adjusted HR 4.49; 95% CI, 2.07–9.74; p<0.001). The rates of TLR for LM-left anterior descending artery (LAD) and left circumflex ostium (LCXos) were significantly higher in the HD group (LMT-LAD: adjusted HR 3.10; 95% CI, 1.31–7.33; p=0.01, LCXos: adjusted HR 2.56; 95% CI, 1.32–4.94; p=0.005). The rate of MI was similar between the 2 groups.
Conclusions
Hemodialysis was strongly associated with adverse events after PCI for ULM distal bifurcation lesions even with cDES.

Abstract
OBJECTIVE To elucidate the mechanisms by which orally administered tacrolimus was not absorbed in a patient following allogeneic hematopoietic stem cell transplantation. CLINICAL COURSE A 17-year-old girl with acute myeloid leukemia underwent HLA-haploidentical peripheral blood stem cell transplantation following fludarabine, busulfan, and total-body irradiation. Graft-vs-host disease prophylaxis was post-transplant cyclophosphamide, followed by intravenous tacrolimus and mycophenolate mofetil. When tacrolimus was switched to oral administration, its blood level declined rapidly, resulting in development of acute graft-vs-host disease, which was ameliorated by switching back to intravenous administration. METHODS/RESULTS To elucidate if impaired tacrolimus absorption could be related to genetic polymorphism of tacrolimus-metabolizing enzymes, we analyzed gene polymorphisms of cytochrome P450 3A4, cytochrome P450 3A5, and multidrug resistance 1 (MDR1). The patient had wild-type cytochrome P450 3A4 (*1/*1) and variant-type cytochrome P450 3A5 (*3/*3), while MDR1 genes (2677A/G, 3435C/C) were wild-type. CONCLUSION Wild-type MDR1 gene product P-glycoprotein expressed in the intestine reduces drug absorption from the gastrointestinal tract and may have contributed to low blood levels of tacrolimus in this patient when tacrolimus was orally administered.

Abstract
The basic properties of a Talbot interferometer implementing pinhole arrays were experimentally and numerically investigated for the improvement of measurement sensitivity of laser wavefront sensors utilized for electron density imaging over discharge plasmas. A numerical simulation using a plane wave decomposition method indicated that the pinhole arrays with a pitch of 300 μm and a pinhole diameter of 150 μm were most suitable for the measurement of the millimetre-scale discharge plasmas, in consideration of the spatial resolution and measurement accuracy. The plane wave decomposition simulation expected that the measurement sensitivity of the 8th-Talbot-length interferometer could be improved by a factor of 4 compared with the previously developed Shack-Hartmann type laser wavefront sensors, which was experimentally verified by the self-image behavior of the pinhole arrays. The Talbot interferometric system was successfully used for electron density imaging over the vacuum arcs generated between a 3-mm gap. The electron density image observed by the Talbot interferometers was in excellent agreement with that visualized by the previously developed Shack-Hartmann sensors. The practical notification for the pinhole array fabrication was also presented.

Abstract
Retroperitoneal leiomyosarcoma is a relatively rare and aggressive tumor. Because of its rarity, it is difficult to arrive at a definite diagnosis preoperatively and to design an effective strategy. Here the authors report a case of peritoneal leiomyosarcoma in which diagnosis was difficult because the clinical course resembled that of ovarian cancer. A 77-year-old woman diagnosed with ovarian cancer underwent laparotomy. The excised tumor contained a necrotic polypoid mass that histologically displayed the features of leiomyosarcoma. The patient received adjuvant chemotherapy with a combination of gemcitabine and docetaxel but died two months after surgery owing to the aggressive behavior of the tumor. Because the preoperative diagnosis in this case was ovarian cancer, arriving at a treatment strategy assuming peritoneal leiomyosarcoma was difficult. If complete surgical resection of tumor is not performed, as in the present case, the prognosis can be extremely poor.

Abstract
The aim of this analysis was to investigate the onset time and significance of maximum volume of polyhydraminios and whether the tter was associated with causes. This was a retrospective cohort study between 2012 and 2014. A total number of 68 singleton pregancies were analyzed. Gestational age at onset of polyhydramnios was 30.0 ± 2.8 (25-36) weeks in maternal factor, 30.0 ± 3.5 (25- 7) weeks in fetal factor, and 32.3 ± 2.0 (27-37) weeks in idiopathic factor. Median of maximum amniotic fluid index (AFI) was gnificantly late onset in idiopathic factor. Diabetes, gestational or pre-existing, was present in all of women (ten cases) in maternal facror. Higher AFI was found to be associated with an increased frequency of prenatally detected congenital anomalies. Abnormal fetal kary- type noted in 18/45 (40%) cases of polyhydramnios. Polyhydramnios diagnosed on ultrasound requires further maternal and fetal iagnostic tests.

Abstract
This was a retrospective cohort study between 2002 and 2011. A total number of 150 singleton pregnancies with preterm premature rupture of membranes (PROM) (before 34 weeks) were analyzed. Histological chorioamnionitis (Blanc grade III) was significantly increased over three days from onset of premature rupture of membranes. The positive relationship was strengthened (odds ratios, 3.5; 95% confidence intervals, 1.5-5.2) over three days from onset of preterm PROM. PROM is a risk factor important for histological chorioamnionitis. To avoid neonatal infection, early termination is recommended in preterm PROM patients.

Abstract
PURPOSE OF INVESTIGATION This study aimed to estimate the effectiveness of hysteroscopic myomectomy for symptomatic submucous uterine fibroids and to identify prognostic factors for persistent or recurrent symptoms. MATERIALS AND METHODS A total of 237 patients who underwent hysteroscopic myomectomy were divided into three groups according to the classification of the European Society for Gynaecological Endoscopy: Type 0 (n=116), Type I (n=97), and Type II (n=24). Medical records and videotape records of all patients were retrospectively reviewed. RESULTS Improvement of symptoms was achieved in 100% of Types 0 and I, and 66.7% of Type II. The five-year cumulative symptom-free rates after hysteroscopic myomectomy were 96.7% ± 1.9%, 87.8% 6.7%, and 44.5% ± 12.7% in Types 0, I, and II, respectively. The mean symptom-free periods were 46.2 ± 2.6, 47.7 ± 2.7, and 24.7 ± 6.3 months in Types 0, I, and II, respectively. Logistic regression analysis showed that co-existence of other myomas and Type II were independent prognostic factors for recurrence of symptoms. CONCLUSION Type I fibroids are a good indication for hysteroscopic myomectomy. In Type II, some patients feel that their symptoms improve, but this curative effect could be temporary.

Abstract
The present authors analyzed patients' backgrounds and pre-surgical findings to clarify the risk factors of rupture of fallopian tubal pregnancy. The surgical findings 113 cases were clearly diagnosed as fallopian tubal pregnancy with or without rupture. Twenty-six cases of fallopian tubal pregnancy were ruptured and 87 cases were not ruptured at the time of operation. The risk factors of fallopian tubal rupture were assessed by Chi-square for independence test and multiple regression analysis. Obesity (BMI over 26), prior birth history, social welfare entitlement, ultrasonography findings of fetal heart movement, and pre-surgical serum beta-hCG level more than 3,000 mIU/ml patient were significantly higher risk in fallopian tubal rupture. Fertility treatment patient were at significantly lower risk for fallopian tubal rupture. Higher beta-hCG levels, especially >3,000 mIU/ml is associated with increased risk of fallopian tubal rupture in ectopic pregnancy.

Abstract
A patient, having been treated by total cystectomy and Bricker's conduit operation for prostatic duct carcinoma with intraepithelial extension into the prostatic urethra and bladder, developed an annular, psoriasiform eruption around the external orifice of the urethra two and one-half years later. A biopsy of this lesion showed pagetoid changes of the epidermis. Microscopic examination of the surgical specimen, consisting of the glans penis and corpus spongiosum, demonstrated intraepithelial-tumor permeation into the glans penis, penile urethra, and periurethral glands (Littre). It seems reasonable to conclude that this is an unusual case of Paget's disease of the glans penis which probably originated from a prostatic duct carcinoma.

Abstract
The spontaneous crescentic glomerulonephritis-forming/Kinjoh (SCG/Kj) mouse, a model of human crescentic glomerulonephritis (CrGN) and systemic vasculitis, is characterized by the production of myeloperoxidase-specific anti-neutrophil cytoplasmic autoantibody (MPO-ANCA) and marked leucocytosis. This study was performed to identify the specific populations of leucocytes associated with CrGN and susceptibility loci for pathogenic leucocytosis. Four hundred and twenty female (C57BL/6 × SCG/Kj) F2 intercross mice were subjected to serial flow cytometry examination of the peripheral blood (PB). Kidney granulocytes and monocytes were examined histopathologically. Linkage analyses were performed with 109 polymorphic microsatellite markers. Correlation studies revealed that increase of the granulocytes, F4/80(+) cells, CD3(+) CD4(-) CD8(-) T cells and dendritic cells (DCs) in peripheral blood (PB) were associated significantly with glomerulonephritis, crescent formation and vasculitis. In kidney sections, F4/80(low) cells were observed in crescent, while F4/80(high) cells were around the Bowman's capsules and in the interstitium. Numbers of F4/80(+) cells in crescents correlated significantly with F4/80(+) cell numbers in PB, but not with numbers of F4/80(+) cells in the interstitium. Genome-wide quantitative trait locus (QTL) mapping revealed three SCG/Kj-derived non-Fas QTLs for leucocytosis, two on chromosome 1 and one on chromosome 17. QTLs on chromosome 1 affected DCs, granulocytes and F4/80(+) cells, but QTL on chromosome 17 affected DCs and granulocytes. We found CrGN-associated leucocytes and susceptibility QTLs with their positional candidate genes. F4/80(+) cells in crescents are considered as recruited inflammatory macrophages. The results provide information for leucocytes to be targeted and genetic elements in CrGN and vasculitis.

Abstract
PURPOSE Mesothelin is a cell surface glycoprotein that is present on normal mesothelial cells and overexpressed in several cancers. In this study, we investigated the methylation/hypomethylation status in the promoter region of the mesothelin gene in gynecological tumors. METHODS Forty-four ovarian tumor specimens and 16 cases of uterine endometrial carcinoma, and normal tissue specimens were used. Monoclonal antibody (5B2) was employed for the immunohistochemical analysis. The methylation-sensitive single-nucleotide primer extension (Ms-SNuPE) technique was used to quantify the methylation/hypomethylation status at 20 CpG sites in the mesothelin promoter region. RESULTS Mesothelin was expressed in 100% of serous cystadenocarcinoma and 100% of serous borderline tumor of the ovary. None of the germ cell tumors and sexcord-stromal tumors was immunoreactive. Fifty percent of endometrial carcinoma was immunoreactive for mesothelin. The average methylation of CpG sites in ovarian tumors ranged from 6-56% (median: 31%) in mesothelin-positive and 13-79% (median: 43%) in mesothelin-negative samples. In endometrial tumors, the average methylation ranged from 5-52% (median: 28%) in mesothlin-positive and from 15-67% (median: 22%) in mesothlin-negative samples. A correlation was found between mesothelin expression and the average methylation/hypomethylation status as well as methylation/hypomethylation status at four of 20 CpG sites in ovarian samples. No correlation was found in endometrial samples. CONCLUSION We detected diverse levels of methylation/hypomethylation at CpG sites in the mesothelin promoter region in ovarian and endometrial tumors. We speculate that, although methylation/hypomethylation changes may affect its transcription, other mechanisms may synergically operate in tissue-specific expression and tumor-related mesothelin overexpression.

Abstract
In Japan and Korea, outbreaks of scuticociliatosis have frequently occurred in Japanese flounder, Paralichthys olivaceus. Morphological observations and small subunit rRNA gene sequences have shown that the causative agent of scuticociliatosis in the flounder is Miamiensis avidus (syn. Philasterides dicentrarchi). In this study, we elucidated the antigenic differences between six Japanese M. avidus isolates as an initial step toward developing an effective vaccine against the disease. Four Japanese flounder isolates (IyoI, Nakajima, JF05To and Mie0301 isolates), one spotted knifejaw, Oplegnathus punctatus, isolate (SK05Kyo), and one ridged-eye flounder, Pleuronichthys cornutus, isolate (RF05To) were subjected to serological analysis. Antisera against IyoI, SK05Kyo, Nakajima and Mie0301 isolates were raised in rabbits and used for immobilization assays and Western blotting. Immobilization assays showed that the six isolates could be divided into three groups, tentatively designated serotype I for IyoI, JF05To, RF05To, SK05Kyo, serotype II for Nakajima and serotype III for Mie0301. Western blotting results supported these three serotypes, with marked similarities in the banding profiles of IyoI, JF05To, RF05To and SK05Kyo isolates, which were distinct from the Nakajima and Mie0301 isolates. Three isolates, IyoI, Nakajima and Mie0301 that were selected as representatives of each serotype, were highly pathogenic to Japanese flounder by experimental infection. Based on these findings, we propose that there are at least three M. avidus serotypes in Japan.

Abstract
DNA has a unique character that allows it to combine with various chemical substrates at the molecular level, and the DNA binding with chemical pollutants can cause serious damage to the organism. The purpose of this research was to apply the strong bonding character of DNA for the removal of mercury ions. In this research, we used DNA condensation promoted by the action of DNA condensing agents, such as cetyltrimethylammonium bromide and a commercially available combination flocculant made of zeolite, to precipitate out the DNA bound with mercury ion in an aqueous solution. When solutions of mercury at 0.02-100 ppm (parts per million) concentrations at a pH range of 2-11 were treated with double-stranded DNA followed by the condensing agent, more than 95% of the mercury ions could be removed after simple filtration or sedimentation.

Abstract
Stokes-Adams attacks are fairly common in children with congenital complete heart block, but the occurrence of cerebral infarction is quite unusual. We present the case of a 13-year-old boy with congenital heart block and an embolic stroke involving the cerebral artery. Echocardiography revealed no valvular regurgitation, hypokinetic segments, mural thrombus, or myxoma. Electrocardiographic monitoring demonstrated good response of ventricular rate to exercise and no episodes of atrial or ventricular dysrhythmia. It is assumed that embolism occurred due to bradycardia.

Abstract
Cornual pregnancy is uncommon among ectopic pregnancies. A diagnosis of cornual pregnancy remains challenging, and rupture of a cornual pregnancy causes catastrophic consequence due to massive bleeding. We report a case of a ruptured cornual pregnancy occurring at 12 weeks of gestation. A 34-year-old woman was suspected of having a left cornual pregnancy at 11 weeks of gestation. Transabdominal ultrasound and magnetic resonance imaging revealed an eccentric localization of a gestational sac containing a viable fetus outside the uterine cavity adjacent to the left uterine cornua. The gestational sac was surrounded with a thin myometrial layer. The patient developed a rupture of the left cornual pregnancy with unstable hemodynamics. She underwent emergency laparotomy, which revealed the ruptured left cornual pregnancy with a hemoperitoneum. Cornual resection was performed. The pathological examination confirmed a ruptured cornual pregnancy.

Abstract
OBJECTIVE Pelvic transcatheter artery embolization (TAE) has been widely used for the management of postpartum hemorrhage (PPH). However, the adverse effects of TAE on the subsequent pregnancy remain poorly understood. CASE A 30-year-old woman, gravida 2, para 1, developed PPH due to atonic bleeding and underwent TAE. Thereafter, her menstrual cycle became irregular with less blood volume. Three years later, she became pregnant despite a thin endometrial thickness of 6 mm during the ovulatory period. She delivered a healthy baby at 39 weeks of gestation. No signs of placental separation were obtained, and an attempt at manual extraction of the placenta failed, followed by massive PPH. She underwent emergent TAE. The placenta was not spontaneously delivered even on day 8 postpartum. A supracervical hysterectomy was performed due to a worsening intrauterine infection. Pathological examination revealed findings compatible with placenta increta. CONCLUSION A TAE-associated thin endometrium may be attributable to the development of placenta increta. Pregnant women undergoing TAE should be managed carefully because the information about pregnancy outcomes after TAE remains scanty.

Abstract
Na+/K+ pump is one of key mechanisms to maintain cell volume. When it is inhibited, cells are at risk of swelling. However, in guinea pig ventricular myocytes, the cell area as an index of cell volume was almost constant during 90 min Na+/K+ pump blockade with 40 microM ouabain despite the marked membrane depolarization. In this study, involvements of Ca2+ transporters and channels in the cardiac cell volume regulation were proposed by conducting the computer simulation in parallel with the experimental validation.
