Abstract
AIM This study aims to examine the real-world effectiveness of education regarding clinical guidelines for psychiatric disorders using 'the Effectiveness of guidelines for dissemination and education in psychiatric treatment (EGUIDE)' project. METHODS The EGUIDE project is a nationwide prospective implementation study of two clinical practice guidelines, i.e., the Guideline for Pharmacological Therapy of Schizophrenia and the Treatment Guidelines for Major Depressive Disorders, in Japan. Between 2016 and 2019, 782 psychiatrists belonging to 176 hospitals with psychiatric wards participated in the project and attended lectures on clinical practice guidelines. The proportions of guideline-recommended treatments in 7405 patients with schizophrenia and 3794 patients with major depressive disorder at participating hospitals were compared between patients under the care of psychiatrists participating in the project and those not participating in the project. Clinical and prescribing data on the patients discharged from April to September each year from participating hospitals of the project were also analyzed. RESULTS The proportions of three quality indicators (antipsychotic monotherapy regardless of whether other psychotropics medication, antipsychotic monotherapy without other psychotropics and no prescription of anxiolytics or hypnotics) for schizophrenia were higher among participating psychiatrists than among nonparticipating psychiatrists. As similar results were obtained in major depressive disorder, the effectiveness of the project for the dissemination of guideline-recommended treatment has been replicated. CONCLUSION This strategy of providing education regarding the clinical guidelines for psychiatric disorders was effective in improving the treatment-related behavior of psychiatrists. The use of this education-based strategy might contribute to resolving the mental health treatment gap.

Abstract
BACKGROUND Although several guidelines recommend monotherapy with antipsychotics for the treatment of schizophrenia, patients who receive long-acting injectable antipsychotics (LAIs) are frequently treated with oral antipsychotics (OAPs). In the present study, we investigated the detailed use of psychotropic medications among patients throughout Japan with schizophrenia who received LAIs or OAPs. METHODS The present study used data from the project for the Effectiveness of Guidelines for Dissemination and Education in psychiatric treatment from 94 facilities in Japan. The LAI group included patients who received any LAI, and the non-LAI group included patients who took only OAP medications at discharge. The participants of this study were 2518 schizophrenia patients (263 in the LAI group and 2255 in the non-LAI group) who received inpatient treatment and had prescription information at discharge between 2016 and 2020. RESULTS This study revealed significantly higher rates of polypharmacy antipsychotics, number of antipsychotics, and chlorpromazine equivalents in the LAI group than in the non-LAI group. In contrast, the LAI group showed lower rate of concomitant use of hypnotic and/or antianxiety medication than the non-LAI group. CONCLUSIONS Presenting these real-world clinical results, we want to encourage clinicians to keep monotherapy in mind for the treatment of schizophrenia, especially by reducing concomitant use of antipsychotics in the LAI group and reducing hypnotic and/or antianxiety medication in the non-LAI group.

Abstract
To disseminate, educate, and validate psychiatric clinical practice guidelines, the Effectiveness of Guidelines for Dissemination and Education in Psychiatric Treatment (EGUIDE) project was launched in 2016. In this study, we investigated whether the web-based courses offered by this project would be as effective as the face-to-face courses. We analyzed and compared survey answers about overall participant satisfaction with the course and answers regarding clinical knowledge of schizophrenia and major depressive disorder between 170 participants who took the web-based courses in 2020 and 689 participants who took the face-to-face courses from 2016 to 2019. The web-based course participants completed the survey questions about satisfaction with the web-based courses. The web-based courses were conducted using a combination of web services to make it as similar as possible to the face-to-face courses. The degree of satisfaction assessed by the general evaluation of the web-based courses was higher than what was expected from the face-to-face courses. The degree of satisfaction was similar for the courses on schizophrenia and major depressive disorder. In addition, there were no significant differences in overall satisfaction and clinical knowledge between web-based and face-to-face courses. In conclusion, the web-based courses on clinical practice guidelines provided by the EGUIDE project were rated as more satisfying than the face-to-face course that the participants expected to take and no differences in the effectiveness of either course. The results suggest that, after the COVID-19 pandemic, it would be possible to disseminate this educational material more widely by adopting web-based courses additionally face-to-face courses.

Abstract
INTRODUCTION Drug-induced extrapyramidal syndrome (EPS) remains a major problem in clinical psychiatry. This study aimed to examine the factor structure of drug-induced extrapyramidal symptoms observed in patients with schizophrenia and assessed using the Drug-Induced Extrapyramidal Symptoms Scale (DIEPSS). METHODS The participants were 1478 patients with a diagnosis of schizophrenia whose EPS was assessed using the DIEPSS in India, Indonesia, Japan, Malaysia, and Taiwan in the 2016 REAP AP-4 study. The records of the participants were randomly divided into two subgroups: the first for exploratory factor analysis of the eight DIEPSS items, and the second for confirmatory factor analysis. RESULTS The factor analysis identified three factors: F1 (gait and bradykinesia), F2 (muscle rigidity and tremor), and F3 (sialorrhea, akathisia, dystonia, and dyskinesia). CONCLUSION The results suggest that the eight individual items of the DIEPSS could be composed of three different mechanisms: acute parkinsonism observed during action (F1), acute parkinsonism observed at rest (F2), and central dopaminergic mechanisms with pathophysiology other than acute parkinsonism (F3).

Abstract
AIM Treatment guidelines are designed to assist patients and health care providers and are used as tools for making treatment decisions in clinical situations. The treatment guidelines of the Japanese Society of Mood Disorders establish treatment recommendations for each severity of depression. The individual fitness score (IFS) was developed as a simple and objective indicator to assess whether individual patients are practicing treatment by the recommendations of the depression treatment guidelines of the Japanese Society of Mood Disorders. METHODS The EGUIDE project members determined the IFS through the modified Delphi method. In this article, the IFS was calculated based on the treatment of depressed patients treated and discharged between 2016 and 2020 at facilities participating in the EGUIDE project. In addition, we compared scores at admission and discharge. RESULTS The study included 428 depressed patients (mild n = 22, moderate/severe n = 331, psychotic n = 75) at 57 facilities. The mean IFS scores by severity were statistically significantly higher at discharge than at admission with moderate/severe depression (mild 36.1 ± 34.2 vs. 41.6 ± 36.9, p = 0.49; moderate/severe 50.2 ± 33.6 vs. 55.7 ± 32.6, p = 2.1 × 10-3; psychotic 47.4 ± 32.9 versus 52.9 ± 36.0, p = 0.23). CONCLUSION We developed the IFS based on the depression treatment guideline, which enables us to objectively determine how close the treatment is to the guideline at the time of evaluation in individual cases. Therefore, the IFS may influence guideline-oriented treatment behavior and lead to the equalization of depression treatment in Japan, including pharmacotherapy.

Abstract
BACKGROUND Several guidelines recommend monotherapy in pharmacotherapy for schizophrenia and major depressive disorder. The content of regular prescriptions has been reported in several studies, but not enough research has been conducted on the content of pharmacotherapy, including pro re nata (PRN) medications. The purpose of this study was to evaluate the content of pharmacotherapy, including PRN medications, and to clarify the relationship with regular prescriptions. METHODS We used data from the "Effectiveness of Guidelines for Dissemination And Education in psychiatric treatment" (EGUIDE) project to investigate the presence or absence of PRN psychotropic medications at discharge for each drug category. We compared the PRN psychotropic prescription ratio at discharge by diagnosis for each drug category. The antipsychotic monotherapy ratio and no prescription ratio of other psychotropics for schizophrenia at discharge and the antidepressant monotherapy ratio and no prescription ratio of other psychotropics for major depressive disorder at discharge were calculated for each regular prescription, including PRN psychotropic medications, as quality indicators (QIs). Spearman's rank correlation test was performed for QI values of regular prescriptions and the QI ratio between regular prescriptions and prescriptions including PRN medications for each diagnosis. RESULTS The PRN psychotropic prescription ratio at discharge was 28.7% for schizophrenia and 30.4% for major depressive disorder, with no significant differences by diagnosis. The prescription ratios of PRN antipsychotic medications and PRN antiparkinsonian medications were significantly higher for schizophrenia. The prescription ratios of PRN anxiolytic and hypnotic and PRN antidepressant medications were significantly higher for patients with major depressive disorder. For both schizophrenia and major depressive disorder, the QI was lower for discharge prescriptions, including PRN medications, than for regular prescriptions. QI values for regular prescriptions and the QI ratio were positively correlated. CONCLUSIONS Considering PRN psychotropic medications, the monotherapy ratio and no prescription ratio of other psychotropics at discharge decreased in pharmacotherapy for schizophrenia and major depressive disorder. A higher ratio of monotherapy and no prescription of other psychotropics on regular prescriptions may result in less concomitant use of PRN psychotropic medications. Further studies are needed to optimize PRN psychotropic prescriptions.

Abstract
AIMS The Guidelines for the Pharmacotherapy of Schizophrenia were established to improve the quality of medical care, and the EGUIDE project was conducted to train clinicians on guideline usage. A quality indicator (QI) was established to measure the prevalence of the guidelines, and a survey was conducted, which revealed a gap between the guidelines and actual clinical practice (evidence-practice-gap). The purpose of this study was to develop an individual fitness score (IFS) formula that expresses the degree to which prescribers adhere to the Guidelines for Pharmacological Therapy of Schizophrenia in a simple manner, and to determine the validity of this formula from a survey of the prescriptions of the EGUIDE project participants'. METHODS To establish appropriate scores, members discussed the proposed formula and then voted on them. The IFS formula developed was set up so that antipsychotic monotherapy would be given 100 points, with points deducted if concomitant or adjunctive antipsychotic medications were used, and a minimum score of 0. To validate this formula, prescriptions of hospitalized schizophrenic patients at admission and at discharge were scored and compared. RESULT IFS points vary and ranged from 0 to100. The average pre-admission score for all subjects was 45.6, and the average score at discharge was 54, those were significantly higher during discharge. CONCLUSIONS We developed an IFS formula, a tool to easily visualize the degree to which current prescriptions conform to the guidelines for the pharmacological treatment of schizophrenia.

Abstract
We previously designed the formulation containing minoxidil (MXD) nanoparticles (MXD-NPs), and found that the MXD-NPs can mainly deliver MXD into hair bulbs via hair follicles pathway, and that the therapeutic efficiency for hair growth is higher in comparison with the formulation containing dissolved MXD. In this study, we investigated whether the skin environmental changes by the treatment of steam towel, ethanol, l-menthol and commercially available (CA) carpronium affect the drug behavior in the MXD-NPs-applied mice. The steam towel, ethanol, l-menthol and CA-carpronium were pre-treated 3 min before MXD-NPs application, and the MXD content in the hair bulge, bulb, skin tissue and blood of mice were measured 4 h after MXD-NPs application. No significant difference of MXD levels in the blood was observed by the pre-treatment of steam towel, ethanol, l-menthol and CA-carpronium. On the other hand, the pre-treatment of steam towel and l-menthol enhanced the MXD levels in hair bulge and/or bulb. Although, the MXD levels in hair bulge and bulb were not changed by the pre-treatment of ethanol, the MXD levels in skin tissue was higher than that of saline-pre-treated group (control). The MXD levels in hair bulge, bulb and skin tissue of mice pre-treated with CA-carpronium were remarkably higher in comparison with control. In conclusion, we showed that the changes in skin environment by the steam towel, ethanol, l-menthol and CA-carpronium affected the absorption of MXD-NPs, and these increased MXD levels in the hair bulb and blood by the combination may enhance the therapeutic efficiency without side effects.

Abstract
PURPOSE In the treatment guidelines for major depressive disorder (MDD), the recommended treatment differs based on the severity. However, the type of treatment provided based on the severity of MDD in real-world clinical practice has not been investigated. In this study, we clarified the actual situation of MDD treatment in clinical practice and compared the treatment based on the severity of MDD. METHODS We used data from 1484 patients with MDD at discharge from October 2016 to March 2020. RESULTS The number of psychotropic prescriptions tended to be lower in those diagnosed with MDD in the severe group compared to in the non-severe group. There were significant differences among the three groups (mild, moderate/severe, and psychotic) in the percentage of patients who were not prescribed antipsychotics (p = 1.9 ×10-6), a combination of antipsychotics and antidepressants (p = 5.0 ×10-4), and the implementation rate of modified electroconvulsive therapy (m-ECT) (p = 3.4 ×10-9). The percentage of patients with a severe diagnosis who underwent m-ECT was higher, which corresponded to the severity. CONCLUSION Our findings showed that the use of psychotropics decreased when the severity of MDD was diagnosed, and the rate of a combination of antipsychotics and antidepressants and the implementation rate of m-ECT increased with the severity. However, this study suggests that there is still an evidence-practice gap in the treatment of MDD in Japan, and guidelines are only partially adhered to in the treatment of depression.

Abstract
We previously found that 1% minoxidil (MXD) nanoparticles prepared using a bead mill method led to an increase I n hair follicle delivery and hair growth in C57BL/6 mice. In the present study, we designed a nanoparticle formulation containing 5% MXD (MXD-NPs) using the bead mill method and investigated the hair-growth effect of MXD-NPs and a commercially available MXD solution (CA-MXD). Hair growth and in vivo permeation studies were conducted using C57BL/6 mice. Moreover, we examined the MXD contents in the upper (hair bulge) and the lower hair follicle (hair bulb) and observed the hair follicle epithelial stem cells (HFSC) by immunohistochemical staining using the CD200 antibody. The mean particle size of the MXD in the MXD-NPs was 139.8 nm ± 8.9 nm. The hair-growth effect of the MXD-NPs was higher than that of CA-MXD, and the MXD content in the hair bulge of mice treated with MXD-NPs was 7.4-fold that of the mice treated with CA-MXD. In addition, the activation of HFSC was observed around the bulge in the MXD-NPs-treated mice. We showed that MXD-NPs enable the accumulation of MXD in the upper hair follicles more efficiently than CA-MXD, leading the activation of HFSC and the hair growth.

Abstract
BACKGROUND Clinical practice guidelines for schizophrenia and major depressive disorder have been published. However, these have not had sufficient penetration in clinical settings. We developed the Effectiveness of Guidelines for Dissemination and Education in Psychiatric Treatment (EGUIDE) project as a dissemination and education programme for psychiatrists. AIMS The aim of this study is to assess the effectiveness of the EGUIDE project on the subjective clinical behaviour of psychiatrists in accordance with clinical practice guidelines before and 1 and 2 years after participation in the programmes. METHOD A total of 607 psychiatrists participated in this study during October 2016 and March 2019. They attended both 1-day educational programmes based on the clinical practice guidelines for schizophrenia and major depressive disorder, and answered web questionnaires about their clinical behaviours before and 1 and 2 years after attending the programmes. We evaluated the changes in clinical behaviours in accordance with the clinical practice guidelines between before and 2 years after the programme. RESULTS All of the scores for clinical behaviours in accordance with clinical practice guidelines were significantly improved after 1 and 2 years compared with before attending the programmes. There were no significant changes in any of the scores between 1 and 2 years after attending. CONCLUSIONS All clinical behaviours in accordance with clinical practice guidelines improved after attending the EGUIDE programme, and were maintained for at least 2 years. The EGUIDE project could contribute to improved guideline-based clinical behaviour among psychiatrists.

Abstract
In several clinical guidelines for schizophrenia, long-term use of anticholinergic drugs is not recommended. We investigated the characteristics of the use of anticholinergics in patients with schizophrenia by considering psychotropic prescription patterns and differences among hospitals. A cross-sectional, retrospective prescription survey at the time of discharge was conducted on 2027 patients with schizophrenia from 69 Japanese hospitals. We examined the relations among psychotropic drug prescriptions regarding anticholinergic prescription. We divided the hospitals into three groups-low rate group (LG), medium rate group (MG), and high rate group (HG)-according to their anticholinergic prescription rates, and analyzed the relationship between anticholinergic prescription rates and antipsychotic prescription. Anticholinergic drugs were prescribed to 618 patients (30.5%), and the prescription rates were significantly higher for high antipsychotic doses, antipsychotic polypharmacy, and first-generation antipsychotics (FGAs) use. The anticholinergic prescription rate varied considerably among hospitals, ranging from 0 to 66.7%, and it was significantly higher in patients with antipsychotic monotherapy, antipsychotic polypharmacy, and normal and high doses of antipsychotics in HG than in those LG and MG. The anticholinergics prescription rate in patients with second-generation antipsychotic monotherapy in HG was also significantly higher than in those LG and MG; however, the difference was no longer significant in patients with FGA monotherapy. Conclusively, in addition to high antipsychotic doses, antipsychotic polypharmacy, and FGA use, hospital characteristics influence the prescribing of anticholinergic drugs.

Abstract
BACKGROUND The decision to initiate clozapine treatment should be made on an individual basis and may be closely related to the early detection of treatment-resistant schizophrenia (TRS), although there is evidence that the early use of clozapine results in a better response to treatment. Therefore, we investigated the relationship between the examination rate of TRS and the prescription rate of clozapine. METHODS After attending a 1-day educational program on schizophrenia based on the "Guidelines for the Pharmacological Treatment of Schizophrenia," we asked the participating facilities to submit records of whether or not TRS was evaluated for each patient. We calculated the clozapine prescription rate from the schizophrenic patients prescribed clozapine and all of the schizophrenic patients. Forty-nine facilities in 2017 were included in the study. RESULTS There were dichotomous distributions in the examination rate of TRS and a non-normal distribution in the prescription rate of clozapine. There was a significant correlation between the prescription rate of clozapine and the examination rate of TRS (rs = 0.531, P = 1.032 × 10-4 ). A significant difference was found in the prescription rate of clozapine between the three groups of facilities according to the examination rate of TRS. CONCLUSION As a preliminary problem for the use of clozapine, in Japan, the examination rate of TRS varies, and there are many facilities that typically do not consider the possibility of TRS; this trend leads to a low rate of clozapine use. Clearly, further clinician training is needed for the early detection and appropriate management of TRS that includes an explanation of TRS and how to introduce clozapine therapy to patients and their families.

Abstract
BACKGROUND Monopharmacy with antipsychotics and antidepressants is the first-line treatment for schizophrenia and major depressive disorder (MDD) in most clinical guidelines, while polypharmacy with psychotropic agents in the treatment of schizophrenia is common in clinical practice. There are no detailed data on the prescription patterns for inpatients with mental illness with reliable diagnoses made by treating psychiatrists. METHODS We gathered prescription data at discharge from 2177 patients with schizophrenia and 1238 patients with MDD from October 2016 to March 2018. RESULTS The patients with schizophrenia aged between 60 and 79 were prescribed lower doses of antipsychotics and hypnotics/anxiolytics than those aged between 40 and 59. There were significant differences between the prescription rate of antipsychotics in the patients with schizophrenia and that of antidepressants in the patients with MDD. The frequency of concomitant drugs such as anti-Parkinson drugs, anxiolytics/hypnotics and mood stabilizers in the subjects with schizophrenia prescribed antipsychotic polypharmacy was significantly higher than that with monotherapy. For the patients with schizophrenia, olanzapine, risperidone, aripiprazole, quetiapine, and blonanserin were the five most prescribed antipsychotics. For the patients with MDD, mirtazapine, duloxetine, escitalopram, trazodone and sertraline were the five most prescribed antidepressants. CONCLUSIONS Our results showed the use of high doses of antipsychotics, high percentages of antipsychotic polypharmacy and concurrent use of hypnotics/anxiolytics in patients with schizophrenia. Notably, these data were collected before intensive instruction regarding the guidelines; therefore, we need to assess the change in the prescription pattern post guideline instruction.

Abstract
It is difficult to maintain sperm in liquid storage for a long time, compared with permanent frozen storage in liquid nitrogen. Antioxidants have been reported to improve the quality and fertility of liquid-stored semen. In this study, we investigated whether antioxidants can extend the motility and fertility of frozen-thawed sperm in liquid storage. Frozen-thawed semen from one Japanese black bull (one ejaculate) was diluted in Tris-citrate-fructose (TCF) diluent with 10% (v/v) egg yolk to a sperm concentration of 1×107 spermmL−1. The antioxidants β-mercaptoethanol (βMe) and glutathione (GSH) were added independently, at various concentrations (0.1, 0.5, 1, and 5mM) to sperm suspensions, and these preparations were compared with Control (no added antioxidant). Sperm suspensions were packaged in centrifuge tubes and placed at 17°C in air and monitored daily until sperm motility had stopped (up to 14 days). Sperm motility was analysed by the Sperm Motility Analysis System (SMAS; Ditect Co. Ltd), and the percentage of progressively motile sperm (straight-line velocity (VSL) of >25μm s−1; Grade A classified by WHO manual), compared with that recorded on Day 0 (100%), was determined each day. For evaluation of fertilizing ability, after incubation in liquid storage for 0, 3, 5, and 7 days, sperm were used for IVF with invitro-matured oocytes (30 oocytes per treatment, three replicates). Embryo development was recorded as the proportion of embryos that reached blastocyst by 8 days after IVF. Data for motility were analysed using one-way ANOVA with Tukey test, and embryo development using chi-squared test. A P-value<0.05 was considered statistically significant. At 7 days, the percentage of progressively motile sperm was significantly higher for 0.5, 1, and 5mM βMe than for Control (30.8%, 48.1%, and 50.3%, vs. 0%, respectively). Treatments with 1 and 5mM βMe maintained some sperm progressive motility for 14 days (9.5% and 14.5%). Treatment with GSH showed the same trend at 7 days (32.2%, 36.3%, and 13.7% for 0.5, 1, and 5mM, vs. 0% for Control); 1 and 5mM GSH maintained sperm progressive motility over 10 days (24.8% and 4.4%). In both antioxidant treatments, embryo development was achieved with sperm stored for up to 5 days (Day 0 vs. Day 5 for 0.1mM βMe: 17.6% vs. 13.8%; for 1.0mM GSH: 26.0% vs. 6.7%; for Control: 17.6% vs. 0%). In this study, antioxidants extended both motility and fertility of frozen-thawed bovine sperm in liquid storage. This result suggests the possibility of application to AI using liquid-stored bovine semen.

Abstract
INTRODUCTION The aim of the present study was to elucidate the foreseeable risk factors for suicidal ideation among Japanese perinatal women. METHODS This cohort study was conducted in Nagoya, Japan, from July 2012 to March 2018. The Edinburgh Postnatal Depression Scale (EPDS) questionnaire was conducted at four time points: early pregnancy, late pregnancy, 5 days postpartum, and 1 month postpartum. A total of 430 women completed the questionnaires. A logistic regression analysis was performed using the presence of suicidal ideation on the EPDS as an objective variable. The explanatory variables were age, presence of physical or mental disease, smoking and drinking habits, education, hospital types, EPDS total score in early pregnancy, bonding, and quality and amount of social support, as well as the history of major depressive disorder (MDD). RESULTS The rate of participants who were suspected of having suicidal ideation at any of the four time points was 11.6% (n=52), with the highest (n=25, 5.8%) at late pregnancy. For suicidal ideation, education level (OR: 1.19; 95% CI: 1.00-1.41; p=0.047), EPDS total points in the pregnancy period (OR: 1.25; 95% CI: 1.16-1.34; p < 0.000), a history of MDD (OR: 2.16; 95% CI: 1.00-4.79; p=0.049), and presence of mental disease (OR: 2.39; 95% CI: 1.00-5.70; p=0.049) were found to be risk factors for suicidal ideation. Age [odds ratio (OR): 0.88; 95% confidence interval (CI): 0.80-0.95; p=.002] and quality of social support (OR: 0.77; 95% CI: 0.60-0.99; p=.041) were found to be protective factors. CONCLUSION Based on these results, effective preventive interventions, such as increasing the quality of social support and confirming the history of depression, should be carried out in pregnant depressive women at the early stage of the perinatal period.

Abstract
Japanese Black beef cattle (JBBC) are a leading Wagyu breed in Japan. Embryo transfers are being used to improve JBBC, a sturdy, fast-maturing breed prized for its marbled beef; however, relevant donor selection techniques have not been fully established. Accordingly, in this study, in order to produce embryos efficiently, we aimed to investigate donor selection techniques based on follicle counts at different time points (Experiment 1) and an associated genetic marker (Experiment 2). Statistical differences were evaluated with Student's t-test or Welch's t-test, regarding P<0.05 as significant. In Experiment 1, we initially targeted 57 JBBCs for evaluation. Their follicle counts were determined by ultrasound 3 days before the start of superovulation (pre), close to the time of follicular wave emergence, and they were grouped according to number of follicles (0-19, 20-29, 30-39, and ≥40). Each cow was administered a tapered dose of FSH-R (20 AU) for superovulation, and then subjected to AI with cryopreserved semen from bulls of proven fecundity. Embryos were collected 7 days after AI by non-surgical intrauterine reflux. Post-AI follicle counts were done before ovulation and did not differ significantly from pre-superovulation follicle count in any group (range: −1.09 to 0.61). We then targeted a further 12 JBBC undergoing superovulation and AI with the same procedures, for counting of follicles at 30 days before (Day −30) embryo recovery (ER), pre-superovulation, and AI, and counting of corpora lutea and large follicles at ER, to investigate correlations between counts. We used decision coefficient (R2), regarding R2 ≥ 0.5 as significant. We found positive correlations (R2) at Day −30 with pre-superovulation (0.91), AI (0.63), and ER (0.63), and at pre-superovulation with AI (0.69) and ER (0.74). In Experiment 2, we targeted 69 JBBCs for detection of mutations in the GRIA1 gene, which encodes inotropic glutamate receptor AMPA1 with a known association with ovulation rate, and embryo yield measurements. DNA obtained from blood was subject to microsatellite polymorphism analysis, for mutations at base 917 of GRIA1 exon 7. We identified 33 cows (48%) as bearers of the wild-type allele (GG), 29 cows (42%) as bearers of the heterozygous mutation (GA), and seven cows (10%) as bearers of the homozygous mutation (AA). Average embryo yield was highest in wild-type cows, followed by heterozygous mutants and then homozygous mutants, and was significantly lower for homozygous mutants than for the other two types. Our study results demonstrated that follicle count before superovulation and GRIA1 gene analysis have utility for selecting donors for embryo transfer in JBBC. Furthermore, follicle counts at the early time point of 30 days before ER can be a useful indicator for this selection.

Abstract
BACKGROUND Postpartum depression (PPD) is a major depressive disorder that occurs after childbirth. Objective diagnostic and predictive methods for PPD are important for early detection and appropriate intervention. DNA methylation has been recognized as a potential biomarker for major depressive disorder. In this study, we used methylation analysis and peripheral blood to search for biomarkers that could to lead to the development a predictive method for PPD. METHODS Study participants included 36 pregnant women (18 cases and 18 controls determined after childbirth). Genome-wide DNA methylation profiles were obtained by analysis with an Infinium Human Methylation 450BeadChip. The association of DNA methylation status at each DNA methylation site with PPD was assessed using linear regression analysis. We also conducted functional enrichment analysis of PPD using The Database for Annotation, Visualization and Integrated Discovery 6.8 to explore enriched functional-related gene groups for PPD. RESULTS In the analysis with postpartum depressed state as an independent variable, the difference in methylation frequency between the postpartum non-depressed group and the postpartum depressed group was small, and sites with genome-wide significant differences were not confirmed. After analysis by The Database for Annotation, Visualization and Integrated Discovery 6.8, we revealed four gene ontology terms, including axon guidance, related to postpartum depression. CONCLUSIONS These findings may help with the development of an objective predictive method for PPD.

Abstract
Carboxylated poly-l-lysine (CPLL) is an ampholytic polymer compound and a polyamino acid with a known functional resemblance to antifreeze proteins. We previously reported that CPLL is an effective cryoprotectant for bovine cells, sperm, and slow-frozen embryos. In this study, we investigated CPLL as a cryoprotectant for vitrified bovine embryos. We developed bovine embryos in vitro and vitrified them at the blastocyst stage. Embryos were equilibrated (3min) and vitrified (1min). Vitrified embryos were cryopreserved in LN (Cryotop® device; Kitazato Corp., Tokyo, Japan) for at least 1 week, thawed with a 0.3M sucrose warming solution, and then cultured in a basal medium (Gibco® medium 199, Grand Island, NY, USA; supplemented with 100µM 2-mercaptoethanol, 10% fetal bovine serum, and antibiotics) at 38.5°C in a humidified atmosphere (5% CO2, 5% O2, 90% N2). We evaluated the embryos morphologically for survival and hatched rate at 0, 24, 48, and 72h post-thawing. In control, the equilibration solution (ES) consisted of 7.5% (vol/vol) dimethyl sulfoxide (DMSO) and 7.5% (vol/vol) ethylene glycol, and the vitrification solution (VS) consisted of 16.5% (vol/vol) DMSO and 16.5% (vol/vol) ethylene glycol and 0.5M sucrose. In this study, CPLL was added to ES and VS at various concentrations instead of DMSO. The CPLL was added at 16.5, 11.0, 5.5, and 2.2% (wt/vol) to VS; respectively, these solutions were named P16.5, P11.0, P5.5, and P2.2. The ES was used 45% CPLL of VS each. Embryos underwent the above procedure concurrently, with testing replicated at least 3 times. We evaluated 88, 34, 38, 44, and 28 embryos with each solution (control, P16.5, P11.0, P5.5, and P2.2, respectively). Results were analysed statistically with a chi-square test and residual analysis, regarding P<0.05 as significant. Survival rates were significantly greater in P11.0 at 24h post-thawing (55.7% v. 89.5%; P<0.05) and in P11.0 and P5.5 at 48h post-thawing (47.7% v. 78.9% and 47.7% v. 79.5%, respectively; P<0.05) relative to controls but showed no significant differences at 0h post-thawing. Hatched rates were significantly greater in P11.0 and P5.5 through 72h post-thawing relative to controls (44.7% v. 22.7% and 52.3% v. 22.7%, respectively; P<0.05). The CPLL improved post-thawing embryo survival and hatched rates when applied during vitrification, thus demonstrating cryoprotective effectiveness. We conclude that CPLL acts as a low-toxicity cryoprotectant for vitrified bovine embryos, and our results are consistent with previous reports of protective CPLL effects for cells and cell membranes.

Abstract
Introduction: The relationship between perinatal depressive symptoms, harm avoidance (HA), and a history of major depressive disorder (MDD) was examined in a prospective cohort study. Methods: This study was conducted from May 1, 2011, to December 31, 2016. A history of MDD was evaluated using the Inventory to Diagnose Depression, Lifetime version during pregnancy. Depressive state and HA were evaluated during pregnancy and at 1 month postnatal using the Edinburgh Postnatal Depression Scale (EPDS) and Temperament and Character Inventory, respectively. The relationship between these variances was examined using structural equation modeling. Results: A total of 338 participants with complete data were included in the present study. Pregnant women with compared with those without a history of MDD were observed to have a significantly higher intensity of HA and more severe depressive symptoms in both the prenatal and postnatal periods. A history of MDD affected the severity of depressive symptoms [standardized path coefficient (SPC) = 0.25, p < 0.001] and the intensity of HA during pregnancy (SPC = 0.36, p < 0.001). The intensity of HA during pregnancy affected that at 1 month postnatal (SPC = 0.78, p < 0.001), while the severity of depressive symptoms as assessed by the EPDS during pregnancy affected that at 1 month postnatal (SPC = 0.41, p < 0.001). The SPC for perinatal HA to postnatal depressive symptoms (SPC = 0.13, p = 0.014) was significant and higher than that for perinatal depressive symptoms to postnatal HA (SPC = 0.06, p = 0.087). Conclusion: The present results suggest that early intervention in pregnant women with a history of MDD or a high intensity of HA is important to prevent postnatal depressive symptoms.

Abstract
Epigallocatechin-3-gallate (EGCG) is a major ingredient of catechin polyphenols, and a strong antioxidant compound. Huang et al. (2018 Asian-australas. J. Anim. Sci.) reported that adding 50μM EGCG can improve the bovine oocyte maturation rate. In this research, we investigated the effect of EGCG supplementation on different periods in bovine IVF. Cumulus-oocyte complex (COC) collected from ovaries of slaughtered cows were cultured in maturation medium (20 to 30 oocytes per 100-µL droplet), which consisted of TCM-199 with Earle’s salts and 25mM HEPES supplemented with 10% (vol/vol) fetal bovine serum (FBS), 1µg mL−1 oestradiol, 0.02mg mL−1 FSH, and antibiotics at 38.5°C in a humidified atmosphere of 5% CO2 in air for 24h (in vitro maturation, IVM). After IVM, COC were fertilized in the fertilization medium (modified Brackett-Oliphant media supplemented with 10 µgmL−1 heparin, 10mM caffeine, and 3mg mL−1 BSA) for 6h using semen of one bull at final sperm concentration of 1×107 mL−1 (IVF). After IVF, COC were denuded and cultured in culture medium [CR1aa supplemented with 10% (vol/vol) FBS and antibiotics] at 38.5°C in a humidified atmosphere of 5% O2, 5% CO2, and 90%N2 for 8 days (in vitro culture, IVC). The EGCG was supplemented at 10, 25, 50, and 100M in IVM medium; 25 and 50 µM in IVF medium; and 50 and 100 µM in IVC medium. After 24h in IVM medium, COC were denuded by pipetting, fixed in 3:1 ethanol:acetic acid for 24h and then checked for nuclear and polar body by using aceto-orcein stain. After 18h in IVF, the pronucleus in zygote was fixed in 3:1 ethanol:acetic acid for 24h and checked by aceto-orcein staining. Embryo development was evaluated by counting the total number of embryos that had reached compacted morula by 6 to 8 days after IVF. Significant differences were analysed by chi-squared test and residual analysis. A P-value<0.05 was considered statistically significant. When EGCG was added to IVM, there was no significant difference of oocyte maturation rate between all concentrations (0v. 10v. 25v. 50v. 100 μM: 73.9% v. 56.7% v. 76.7% v. 72.7% v. 63.5%). When EGCG was added to IVF, there was no significant difference of fertilized rate (0v. 25v. 50 μM: 59.4% v. 73.7% v. 64.9%). When EGCG was added to IVC, there was no significant difference in development rate (0v. 50v. 100 μM: 26.2% v. 15.7% v. 22.0%). In this research, EGCG addition did not affect bovine in vitro fertilization.

Abstract
BACKGROUND Although previous studies have reported associations between bonding failure, depression, social support among mothers, and perceived rearing, the causal relationships remain unclear. METHODS A total of 855 women (mean age, 32.4 ± 4.4 years) completed the Mother-Infant Bonding Questionnaire (MIBQ), the Edinburgh Postnatal Depression Scale (EPDS), the Japanese version of the Social Support Questionnaire, and the Parental Bonding Instrument in early pregnancy before week 25 (T1) and at 1 month after delivery (T2). We created a path model to clarify the causal relationships between perinatal bonding failure, depression, social support, and perceived rearing during pregnancy and at 1 month after delivery. The model was tested using structural equation modeling. RESULTS Our recursive model showed acceptable fit (chi-squared statistic/degree of freedom = 2.1, comparative fit index = 0.98, root mean square error of approximation = 0.04). It was revealed that: (1) at T1, higher overprotection significantly predicted MIBQ scores; (2) at T1, poorer social support significantly predicted both MIBQ and EPDS scores; and (3) at T1, both MIBQ and EPDS scores significantly predicted respective scores at T2. CONCLUSIONS These results showed that bonding failure in the postpartum period was significantly influenced by mothers' own perceived rearing and social support during pregnancy. In addition, depression in the postpartum period was strongly influenced by social support during pregnancy. These findings suggest that psychosocial interventions that focus on both mothers' recollections of their own upbringing and social support during pregnancy are effective for preventing bonding failure and depression in the postpartum period.

Abstract
This study aimed to assess the situation of postpartum depression and maternal bonding in Nagoya, a city distant from the epicenter of the Great East Japan Earthquake that occurred on March 11, 2011. Among the participants at 1 month after childbirth between March 11, 2010 and March 10, 2013 (n = 188), 152 fully responded to the Edinburgh Postnatal Depression Scale (EPDS) and Mother–Infant Bonding Questionnaire (MIBQ). They were divided into pre-quake (n = 58), and 0–6, 6–12, 12–18, and 18–24 months after the earthquake groups (n = 20, 26, 29, and 19, respectively). The rate of mothers who scored above the cutoff point for the EPDS increased from 12.1% in the pre-quake to 35.0% in the 0–6 months group (p = 0.022). The EPDS total and anxiety subscale scores (mean ± standard error) were also significantly different between the pre-quake and 0–6 months after the earthquake groups (4.45 ± 0.50 vs. 7.95 ± 1.47, p = 0.024; 2.16 ± 0.26 vs. 3.65 ± 0.57, p = 0.021, respectively). The EPDS total and anxiety scores were the highest for the 0–6 months group, followed by the 6–12, 12–18, 18–24 months groups (p = 0.019, p = 0.022). MIBQ scores did not differ between the pre-quake and 0–6 months groups. Depressive symptoms, mainly explained by anxiety, increased after the earthquake with no changes in maternal bonding.

Abstract
Background: The Highs scale has been developed to evaluate hypomanic symptoms in the first postpartum week. However, it has not been elucidated whether this scale is also applicable to pregnant women. To address this issue, we confirmed the factor structure, reliability, and validity of the Japanese version of the Highs scale for pregnant and postpartum women. Methods: 418 women provided effective responses to both the Highs scale and the Edinburgh Postnatal Depression Scale (EPDS) during early pregnancy (before week 25), late pregnancy (around week 36), at 5 days and at 1 month after delivery. Subjects were randomly divided into two groups, and exploratory and confirmatory factor analyses were performed for each group. Cronbach's alpha was calculated and the correlation of the Highs scale with EPDS was analyzed. The correlation between the subscales was analyzed at four time points, and the correlation of subscales between the four time points was confirmed. Results: This scale was found to have the two-factor structure with elation and agitation subscales. The two subscales had reasonable internal consistency at all time points (Cronbach's alpha range: Factor 1, 0.696-0.758; Factor 2, 0.553-0.694). The overall scale had reasonable internal consistency at all time points (Cronbach's alpha range: 0.672-0.738). Based on the correlation analysis of the two subscales and EPDS, discriminative and convergent validity were indicated at all time points, confirming the construct validity of the Highs scale. Subscale scores showed a significant correlation with EPDS at all time points (r = 0.388, 0.384, 0.498, and 0.442, p < 0.01). Conclusions: The Japanese version of the Highs scale is reliable and valid, and can be applied for evaluating the hypomanic symptoms during pregnancy and postpartum period.

Abstract
Carboxylated poly-l-lysine (CPLL), an ampholytic polymer compound, is reported to have a cryoprotective property similar to that of antifreeze proteins. We previously reported the effectiveness of CPLL as cryoprotective material for bovine sperm (43rd Annual Conference of International Embryo Technology Society, Austin, TX, USA; http://www.iets.org/2017/IETS_2017_Program_Book_FINAL.pdf). In this research, we investigated additional aspects of CPLL for bovine sperm. The conventional cryopreservation medium used for Control group consisted of 6.5% (v/v) glycerin, and the cryopreservation medium used for the CPLL group consisted of 3.25% (v/v) glycerin and 0.5% CPLL (w/v). In experiment 1, sperm motility was measured 1, 3, and 6 h after thawing. The post-thaw motility was assessed by using Sperm Motility Analysis System (DITECT Corp., Tokyo, Japan). The CPLL treatment yielded better motility rate at 6 h (Control v. CPLL; 23.7% v. 38.5%; P < 0.01), average path velocity (μm s−1) at 1 and 3 h (Control v. CPLL; 49.8 v. 57.7, 35.8 v. 42.8; P < 0.01), straight-line velocity (μm s−1) at 1 h (Control v. CPLL; 35.2 v. 45.7; P < 0.01), and curvilinear velocity (μm/s) at 1 and 3 h (Control v. CPLL; 93.7 v. 106.2, 59.9 v. 68.4; P < 0.01) than the Control. In experiment 2, sperm membrane integrity was assessed by using the LIVE/DEAD Sperm Viability Kit (Thermo Fisher Scientific K.K., Kanagawa, Japan). The CPLL group yielded greater sperm membrane integrity rate than control (Control v. CPLL; 49.6% v. 60.6%; P < 0.01). In experiment 3, AI was carried out on 111 cows (Control v. CPLL; 49 v. 62) and the conception rate of the CPLL group was significantly higher than that of the control group (53.1% v. 79.0%; P < 0.01). Previously, we reported the effectiveness of CPLL for bovine sperm. In this study, we clarified how CPLL works to improve the conception rate of AI: CPLL maintains post-thaw motility and protects the sperm membrane. These results suggest that CPLL has potential as a new cryoprotective material for bovine sperm.

Abstract
AIM Although the association between maternal depression and bonding failure during pregnancy and after delivery has been investigated, the causal relationships remain unclear. METHODS A total of 751 women (mean [SD] age, 32.1 [4.4] years) completed the Mother-Infant Bonding Questionnaire and the Edinburgh Postnatal Depression Scale during early pregnancy before week 25 (T1), during late pregnancy around week 36 (T2), and at 5 days after delivery (T3). We created a structural regression model to clarify the relationships between depressive mood and bonding failure during pregnancy and at 5 days after delivery. The model was tested with structural equation modeling. RESULTS Our non-recursive model fit the data well, and we found that: (i) during T2, bonding failure predicted depressive mood (P < 0.01, r = 0.23); (ii) at T3, bonding failure predicted depressive mood (P < 0.05, r = 0.31); (iii) during T1, depressive mood was correlated with bonding failure (P < 0.01, r = 0.45); (iv) depressive mood during T1 predicted depressive mood during T2 (P < 0.01, r = 0.58); (v) depressive mood during T2 predicted depressive mood at T3 (P < 0.01, r = 0.45); (vi) bonding failure during T1 predicted bonding failure during T2 (P < 0.01, r = 0.84); and (vii) bonding failure during T2 predicted bonding failure at T3 (P < 0.01, r = 0.44). The determinant coefficients of depressive mood and bonding failure at T3 were 0.41 and 0.28, respectively. CONCLUSION Our large-scale cohort study indicates that bonding failure predicts depressive mood during pregnancy and 5 days after delivery. These findings suggest that protection and support for pregnant women with depressive mood and bonding failure may prevent both issues during pregnancy and the early stage after delivery.

Abstract
Causal relationships between perinatal bonding failure, depression, and social support among mothers remain unclear. A total of 494 women (mean age 32.4 ± 4.5 years) completed the Mother-Infant Bonding Questionnaire (MIBQ), the Edinburgh Postnatal Depression Scale (EPDS), and the Japanese version of the Social Support Questionnaire in early pregnancy before week 25 (T1) and 1 month after delivery (T2). Our model of recursive structured equation modeling (SEM) showed acceptable fit (CMIN/df = 2.2, CFI = 0.97, and RMSEA = 0.05). It was revealed that: (1) a lower number of supportive persons at T1 significantly predicted both MIBQ and EPDS scores at T1 and T2; (2) at T1, poorer satisfaction with the social support received significantly predicted EPDS scores; (3) both MIBQ and EPDS scores at T1 significantly predicted their respective scores at T2. Out cohort study indicates that the number of individuals who are available to provide social support and the degree of satisfaction with the level of social support received during pregnancy have a great influence on bonding failure and depression in the postpartum period. These findings suggest that psychosocial interventions that focus on these two aspects of social support during pregnancy are effective in preventing bonding failure and depression in the postpartum period.

For cell cryopreservation, dimethyl sulfoxide (DMSO) have been used widely as cryoprotective material for long time. Carboxylated poly-l-lysine (CPLL) is an ampholytic polymer compound obtained by converting 65% amino groups to carboxyl groups after synthesising ε-poly-l-lysine aqueous solution and succinic anhydride. It is reported that the addition of CPLL into cryopreservation medium improves the post-thaw survival rate of murine L929 cells, human induced pluripotent stem cells and murine embryo. In this research, the effectiveness of CPLL as bovine somatic cell cryoprotective material was examined. In experiment 1, using bovine fibroblast cells from skin, the cryopreservation media were prepared as follows: 10% (vol/vol) DMSO, 5% (vol/vol) DMSO + 5% (wt/vol) CPLL, 5% (wt/vol) CPLL, 7.5% (wt/vol) CPLL, 10% (wt/vol) CPLL and 20% (wt/vol) CPLL were dissolved in DMEM and pH was adjusted to 7.4. Cells were resuspended in 1 mL of cryopreservation medium at a cell density of 5 × 105 and stored in a −80°C freezer. After storage for at least 1 wk, cells were thawed. The 5% CPLL showed significantly higher post-thaw survival rate than 10% DMSO (96.5% v. 86.7%; P < 0.05), and 7.5% CPLL and 20% CPLL showed significantly higher proliferation rates than 10% DMSO at 72 h after thawing (10% DMSO v. 7.5% CPLL v. 20% CPLL ; 99.4% v. 173.6% v. 207.4%; P < 0.05). Although it is necessary to remove the cryoprotective material after thawing, the proliferation rate at 72 h after thawing of 5% CPLL and 10% CPLL without removal of cryoprotective material were significantly higher than that when removing cryoprotective material (111.2% v. 269.6%, 113.0% v. 210.0%). In addition, there was no difference between the removal treatment of CPLL and the NOT removal treatment of CPLL at the thawing. In experiment 2, using bovine cumulus cells, the cryopreservation media were prepared as follows: 10% (vol/vol) DMSO, 5% (vol/vol) DMSO + 5% (wt/vol) CPLL, 5% (wt/vol) CPLL, 10% (wt/vol) CPLL, 20% (wt/vol) CPLL, 25% (wt/vol) CPLL, and 30% (wt/vol) CPLL were dissolved in DMEM and other conditions were the same as experiment 1. There was no significant difference for post-thaw survival rate (93.7, 91.8, 89.2, 89.2, 95.3, 91.6, and 90.2%). At 72 h after thawing, 10% DMSO, 5% DMSO + 5% CPLL and 25% CPLL showed higher proliferation rate (10% DMSO v. 5% DMSO + 5% CPLL v. 25% CPLL; 258.4% v. 281.4% v. 257.4%). The significant differences in survival rate were determined by chi-squared test, and in proliferation were determined by ANOVA. In bovine somatic cells, it was possible to cryopreserve cells using CPLL without DMSO. The cryoprotective effect of CPLL is equal or superior to that of DMSO, the conventional cryoprotective material. Further, when using CPLL, it was possible to culture without removing the cryopreservation medium after thawing. These results suggest that CPLL has promise as a new cryoprotective material for bovine somatic cells.

Abstract
Carboxylated poly-l-lysine (CPLL) is an ampholytic polymer compound, and it is obtained by converting 65% amino groups to carboxyl groups after synthesising ε-poly-l-lysine aqueous solution and succinic anhydride. CPLL has cryoprotective property similar to antifreeze protein, and addition of CPLL into cryopreservation medium improves the post-thaw survival rate of cells and embryos. In this research, we examined the effectiveness of CPLL as a bovine germ cell cryoprotective material. In experiment 1 (in sperm), the conventional cryopreservation medium used for control group was consisted of 6.5% (vol/vol) glycerin, and the cryopreservation medium used for CPLL group was consisted of 3.25% (vol/vol) glycerin and 0.5% CPLL (wt/vol). The post-thaw survival and motility were assessed by using Sperm Motility Analysis System (DITECT Corp., Tokyo, Japan). There was no significant difference for post-thaw survival rate and motility (control v. CPLL; 98.8% v. 96.6% and 69.7% v. 62.2%, respectively). Artificial insemination was carried out in 65 cows (control v. CPLL; 34 v. 31), and the conception rate of the CPLL group was higher than that of the control group (80.6% v. 67.6%; P = 0.23). In experiment 2 (embryos), the conventional cryopreservation medium used for control group was consisted of 5% (vol/vol) ethylene glycol and 6% (vol/vol) propylene glycol in PBS. In the CPLL group, 7% (wt/vol) CPLL was added to the conventional medium. In vitro fertilization embryos were cryopreserved at Day 7 and Day 8. There was no significant difference in survival rate at 0, 24, and 48 h and hatched rate until 72 h after thawing (control v. CPLL: 93.6% v. 93.2%, 69.0% v. 64.7%, 56.1% v. 56.3%, 12.9% v. 10.2%, respectively). Embryos obtained by superovulation treatment and in vivo fertilization at Day 7 were cryopreserved using above 2 media, and transferred non-surgically into synchronized recipient cows (1 embryo per animal). Embryo transfer (ET) was carried out in 81 cows (control v. CPLL: 31 v. 50), and recipients were diagnosed for pregnancy ultrasonically 50 days after embryo transfer. Conception rate of CPLL group was higher than control group (50.0% v. 29.0%; P = 0.063). In both experiments, the significant differences between control group and CPLL group were determined by chi-squared test. The effectiveness of CPLL in cells and embryos has been reported; however, there is no report using CPLL in bovine germ cells. In this research, CPLL improved the conception rate of AI and ET, probably due to its low toxicity and protection of the cell membrane. These results suggest that CPLL is available as a new cryoprotective material for bovine sperm and embryo in slow freezing methods.

Abstract
Outpatients undergoing chemotherapy receive oral anticancer drugs, supportive care medicine, and drugs for complications from health insurance pharmacies(ie, drugstores). Therefore, drugstore personnel and patients were surveyed using a questionnaire to ascertain the current conditions of information sharing between drugstores and hospitals. Only 31% of the patients surveyed responded that they received cancer chemotherapy via the drugstores, while a few of them understood the need for information sharing with the drugstore. We also found that the drugstores required a considerable amount of patient information including prescribed therapeutic drugs, treatment regimens, disease conditions, and test value. Therefore, we held a study session and clinical conference to facilitate the creation of an information-sharing system. In conclusion, it is imperative for drugstores and hospitals to cooperate and establish a strategy for information sharing in the future.

Abstract
BACKGROUND The Mother-Infant Bonding Questionnaire (MIBQ) has been widely used to assess maternal emotional involvement with infants. Although the reliability and validity of the MIBQ in the postpartum period has been confirmed, it remains unclear whether the MIBQ is appropriate to assess maternal bonding in both pregnancy and the postpartum period over time. Our study were aimed to 1) examine the reliability and validity of the MIBQ for clinical use among pregnant and postpartum women; and 2) examine the factor structure of the items, create subscales, and confirm the stability of the MIBQ in the pregnancy and postpartum periods. METHODS Participants (n = 751, mean age 32.1 ± 4.4 years) completed the MIBQ and the Edinburgh Postnatal Depression Scale (EPDS) in early pregnancy (before week 25), in late pregnancy (around week 36), 5 days after delivery, and 1 month after delivery. We randomly divided participants into two sample sets. We conducted an exploratory factor analysis of the nine MIBQ items using data from one group of mothers (Group 1; n = 376) in all four periods. The factor structure derived from the exploratory factor analysis was confirmed by a confirmatory factor analysis in the second group (Group 2; n = 375) of mothers in all four periods. RESULTS Exploratory factor analysis yielded two factors: Lack of Affection (LA) and Anger and Rejection (AR). Confirmatory factor analysis demonstrated that LA and AR factors existed for the MIBQ in all periods. Cronbach's alpha coefficients were 0.879 and 0.584, respectively. The scores for LA and AR were significantly correlated over the four time periods. Mothers with higher AR scores on the MIBQ at any of the four periods had higher scores on the EPDS. CONCLUSIONS The MIBQ has two subscales regardless of the timing of the assessment. The MIBQ is appropriate for pregnant as well as postpartum women to assess maternal bonding toward the fetus and infant.

Abstract
Although the association between social support and postpartum depression has been previously investigated, its causal relationship remains unclear. Therefore, we examined prospectively whether social support during pregnancy affected postpartum depression. Social support and depressive symptoms were assessed by Japanese version of Social Support Questionnaire (J-SSQ) and Edinburgh Postnatal Depression Scale (EPDS), among 877 pregnant women in early pregnancy and at one month postpartum. First, J-SSQ was standardized among peripartum women. The J-SSQ was found to have a two-factor structure, with Number and Satisfaction subscales, by exploratory and confirmatory factor analyses. Analysis of covariance was performed to examine how EPDS and J-SSQ scores during pregnancy affected the EPDS score at postpartum. Significant associations were found between postpartum EPDS score and both EPDS and total scores on the Number subscales during pregnancy (β = 0.488 and -0.054, ps < 0.001). Specifically, this negative correlation was stronger in depressive than non-depressive groups. Meanwhile, total score on Satisfaction subscales was not significantly associated with postpartum EPDS score. These results suggest that having a larger number of supportive persons during pregnancy helps protect against postpartum depression, and that this effect is greater in depressive than non-depressive pregnant women. This finding is expected to be vitally important in preventive interventions.

Abstract
Background The Edinburgh Postnatal Depression Scale (EPDS) is a widely used screening tool for postpartum depression (PPD). Although the reliability and validity of EPDS in Japanese has been confirmed and the prevalence of PPD is found to be about the same as Western countries, the factor structure of the Japanese version of EPDS has not been elucidated yet. Methods 690 Japanese mothers completed all items of the EPDS at 1 month postpartum. We divided them randomly into two sample sets. The first sample set (n = 345) was used for exploratory factor analysis, and the second sample set was used (n = 345) for confirmatory factor analysis. Results The result of exploratory factor analysis indicated a three-factor model consisting of anxiety, depression and anhedonia. The results of confirmatory factor analysis suggested that the anxiety and anhedonia factors existed for EPDS in a sample of Japanese women at 1 month postpartum. The depression factor varies by the models of acceptable fit. Conclusions We examined EPDS scores. As a result, “anxiety” and “anhedonia” exist for EPDS among postpartum women in Japan as already reported in Western countries. Cross-cultural research is needed for future research.

Abstract
The objective of the present field study was to establish the beneficial effects of re-insemination of non-pregnant cows using ultrasonography 20 to 23 days after the artificial insemination. A total of 245 Japanese Black cows were artificially inseminated and early pregnancy diagnosis (EPD) was performed on 92 cows 20 days after insemination, using ultrasonography. The remaining 153 cows were considered as negative controls in which routine rectal palpation was performed for pregnancy diagnosis 45-50 days post-insemination. EPD revealed that eleven of the 92 cows (12%) were infertile due to ovarian abnormalities and were thus excluded from the rest of the study. Forty-eight (59%) of the remaining 81 cows were diagnosed as pregnant, while the other 33 (41%) were diagnosed as non-pregnant. Of these non-pregnant cows, 17 of them received a dose of an analogue of the gonadotropin-releasing hormone (GnRH analogue) and were then timed-inseminated, while the other 16 were observed for estrus signs, and 13 of them (81%) were artificially inseminated. Rates of conception were 35% and 38% in the GnRH and the artificially inseminated groups, respectively (P>0.05). Total pregnancy rate for the EPD group increased significantly (74%) (P<0.01) when compared to the control cows (54%) within the same period. In conclusion, our field study demonstrated that re-insemination of non-pregnant cows following EPD is highly efficacious not only in improving the rate of fertility via reducing inter-insemination and inter-calving intervals, but also aids in the early detection of ovarian disorders.

This study tested whether embryo development yield using in vitro fertilization (IVF) could be improved by rocking cultures. Bovine ovaries were obtained at a slaughterhouse and transported to the laboratory within 6 h. Cumulus–oocyte complexes were collected and 20–25 were transferred in 100-μL drops of TCM-199 containing 10% fetal bovine serum and antibiotics under paraffin oil. Maturation was for 20–24 h at 38.5°C under 5% CO2 and 95% air in a humid atmosphere (IVM). In vitro fertilization was carried out for 6 h using frozen–thawed sperm from a single bull in modified Brackett and Oliphant (BO) medium. Presumptive zygotes were cultured in CR1aa supplemented with 10 mg mL–1 of BSA or 5% FBS for 9 d at 38.5°C under 5% CO2, 5% O2, and 90% N2 in a humid atmosphere (IVC). Rocking was performed to a height of 6 cm every 7 s using a Profile Rocker (New Brunswick Scientific Co., Edison, NJ, USA) in an incubator. Dishes were placed at a 15-cm distance from the fulcrum of the rocker. The conventional method (no rocking) served as a control, and every experiment was replicated 3 times. For Experiment 1, the effect of the period of rocking on developmental competence was examined when COC or zygotes were subjected to rocking for IVM, IVF, or IVC (IVM-move, IVF-move, and IVC-move). There were no significant differences in rates of oocyte maturation, cleavage, and development for IVM-move v. the control, or for rate of development between IVC-move and the control. However, the rate of fertilization for IVF-move was higher than that of the control (88.9 v. 67.5%; P < 0.01), and the rate of development was higher for IVF-move than for the control (39.0 v. 25.7%; P < 0.05). For Experiment 2, the effect of rocking frequency during IVF on development was determined. The IVF cultures were rocked every 7, 3.5, and 1.5 s (IVF-1move, IVF-2move, IVF-3move). The rates of cleavage on IVF-1move, IVF-2move, IVF-3move, and the control were 74.3, 69.8, 68.8, and 60.4%, and the rates of development were 39.0, 48.3, 26.2, and 25.7%, respectively. The rates of development on IVF-1move and IVF-2move were significantly different from the control and IVF-3move (P < 0.01). These results showed that rocking during IVF improved fertilization and embryo yield, and that frequency of rocking affected embryo development.

Abstract
The present study aims to establish a novel practical protocol for early pregnancy diagnosis in cows by using transrectal ultrasonography. The protocol is based on measurements of corpus luteum (CL) cross-sectional area (CL c-s area) change performed at 2 separate days before the coming estrus after AI. Fourteen cows were inseminated artificially, and transrectal ultrasonographical observation of the ovaries and blood collection for measurement of peripheral plasma progesterone (P4) concentration were carried out daily from Days 12 to 23 (Day 0 = the day of onset of estrus). Thereafter, cows were routinely diagnosed for pregnancy at Day 30 by transrectal ultrasonography. The largest CL c-s area was obtained at Day 14 in both pregnant and non-pregnant cows. Seven out of 8 non-pregnant cows showed significant CL c-s area regression between Days 14 and 20 (422 ± 112 v. 249 ± 63 mm2), whereas no regression was observed between Days 14 and 20 in pregnant cows (416 ± 65 v. 402 ± 78 mm2). The regression in the CL c-s area between pregnant and non-pregnant cows was significantly different during Day 18 (424 ± 65 v. 288 ± 88 mm2) to Day 23 (402 ± 71 v. 139 ± 64 mm2). P4 concentration was significantly low (less than 1 ng mL–1) at Day 20 in 3 out of 8 non-pregnant cows, whereas the pregnant cows showed significant increase of P4 between Days 14 and 20 (2.6 ± 0.2 v. 3.4 ± 0.5 ng mL–1). The pregnant cows showed significantly higher P4 concentration starting from Day 18 than non-pregnant cows. However, in non-pregnant cows, 4 cows returned to estrus on Day 20 or after, 3 cows showed no signs of estrus, and 1 cow came in estrus as early as Day 18 after AI. In conclusion, the results of the present study suggest that measuring the change in the CL c-s area at Days 14 and 20 makes it possible to detect the non-pregnant cows at Day 20 after AI. However, it was also indicated that measuring the change of P4 concentrations on the same days did not always successfully detect non-pregnant cows. The new protocol based on CL c-s area regression rate can detect almost certainly non-pregnant cows at Day 20 after AI. It is suggested that this method is advantageous in research and industrial breeding.

Abstract
Ganglioneuromas are benign, slow-growing tumors originating from sympathetic nerves or peripheral nerves, often associated with multiple tumor syndromes. They occasionally occur as spinal lesions and grow within the spinal canal or as paraspinal lesions. In this report, we describe a rare solitary ganglioneuroma arising from the cervical nerve root (C8) within the intervertebral foramen in adults. The tumor could be detected as a mass limited to the neuroforamen at an early stage by MR images. Unilateral microsurgical foraminotomy and EN BLOC resection of the tumor resulted in disappearance of the symptoms. Microsurgical resection of the relevant nerve root through limited medial foraminotomy at an intricate anatomical region of the cervico-thoracic junction was appropriate in the current case for complete resection of the tumor as well as to prevent postoperative structural weakness that could result in late segmental instability.

Abstract
The present study investigated whether the endogenous pro-inflammatory cytokines [interleukin (IL)-1beta and tumor necrosis factor-alpha (TNF-alpha)]-dependent expression of cyclooxygenase-2 (COX-2) mRNA within the spinal cord could be involved in the development of chronic inflammatory pain-like behaviors in mice. We demonstrated that the expression of COX-2 mRNA on the ipsilateral side of the spinal cord was significantly increased 6 h and 3 days after intraplantar injection of complete Freund's adjuvant (CFA), compared with the expression in saline-treated mice. In addition, the chronic pain-like behaviors following CFA injection were markedly suppressed by repeated intrathecal (i.t.) pre-treatment with the COX-2 inhibitor etodolac, but not with the COX-1 inhibitor mofezolac. The cytosolic level of the activated form of nuclear factor-kappa B (NF-kappaB), which is a major contributor to the induction of COX-2, on the ipsilateral side of the mouse spinal cord was also increased compared with that in the saline-treated mice. The key finding in the present study was that a single i.t. injection with either IL-1beta or TNF-alpha induced a marked increase in spinal COX-2 mRNA and persistent thermal hyperalgesia in mice. Furthermore, CFA-induced hypersensitivity to inflammatory pain was significantly reduced by repeated i.t. pre-injection of the recombinant Fc chimera of IL-1 receptor I or soluble TNF receptor I, which sequesters endogenous IL-1beta or TNF-alpha, respectively. In contrast, the expression of spinal COX-2 mRNA in CFA-treated mice was similar to that in saline-treated mice at 7 days after CFA injection. The present findings strongly indicate the early intrathecal use of the COX-2 inhibitor for the relief of chronic inflammatory pain. Furthermore, together with the result in a previous study that pro-inflammatory cytokines lead to stimulation of a NF-kappaB-dependent transcriptional pathway, these findings suggest that a spinal cytokine/NF-kappaB/COX-2 pathway may play an important role in the development, but not maintenance, of chronic pain following peripheral tissue inflammation.

Abstract
Somatic cell nuclear transfer (cloning) returns a differentiated cell to a totipotent status; a process termed nuclear reprogramming. Nuclear transfer has potential applications in agriculture and biomedicine, but is limited by low efficiency. To understand the deficiencies of nuclear reprogramming, our research has focused on both candidate genes (imprinted and X-linked genes) and global gene expression patterns in cloned bovine embryos/offspring as compared to those generated by conventional reproduction. We found aberrant expression patterns of H19 and Igf2r as well as X-linked genes in term cloned calves. The expression profiles of cloned blastocysts, however, closely resembled those of the naturally fertilized embryos but were considerably different from those of their nuclear donor cells. Our findings suggest that cloned embryos have undergone significant nuclear reprogramming by the blastocyst stage. However, it is possible that during re-differentiation in later development gene expression aberrancies occur. Additionally, small initial nuclear reprogramming errors may be manifested during subsequent development.
