Abstract
Context Given the dramatic decline in Japan's labor force, promoting women's participation in the workforce is essential. Aims We aimed to take a Hiroshima company as an example and analyze the influencing factors of health literacy (HL) to clarify the issues of the active participation of female employees. Methods and Materials From February to March 2023, a cross-sectional study was conducted by a company in Hiroshima prefecture that contained many male employees. A total of 1,114 valid respondents were received. Employees' demographics, menstrual-related concerns, women's activity promotion support, and HL were investigated in this study. Statistical Analysis Used The Chi-square test and logistic regression using SPSS statistical software version 25 were used. Results There were significant differences between high and low HL with age, women's menstrual problems, and women's activity promotion support. The participants who were unaware of women's menstrual-related problems and their company's implementation of women's activity promotion support were more likely to have high HL. In addition, female employees (including female management) and male management have significantly different cognitions about women's activity promotion support. Conclusions This study found that overall HL among employees in male-dominated companies is low, even among participants who were aware of women's menstruation-related health issues and the company's women's activity promotion support. Increased women's representation in management can bridge policy perception gaps. Male-dominated companies should enhance HL via career programs, health education, and improved communication for active female engagement.

Abstract
BACKGROUND AND OBJECTIVES Japanese women face many female-specific health problems in the workplace, especially menstruation-related issues, which can adversely affect their quality of life and productivity. This study aims to examine how female employees in a male-dominated company in Hiroshima, Japan, cope with menstruation-related health issues in the workplace and the factors that influence their coping strategies. MATERIALS AND METHODS This study used a cross-sectional survey research method. The survey investigated age, health, and menstrual-related issues, as well as women's active participation support and health literacy (HL) levels. The sample population included employees of a manufacturer in Hiroshima prefecture. The data were collected from February 20 to March 10, 2023. The analysis subjects were 171 women who had experienced menstruation-related, women-specific health issues in the workplace. Their attitudes toward menstruation-related issues could influence their experiences. They were categorized into positive and negative groups based on their attitudes toward coping with women's health issues. Chi-square tests and logistic regression analysis were used to compare the two groups. RESULTS The study found that 50.3% (N = 296) of female employees had experienced women's menstruation-related health issues at work. As many as 62.6% (N = 171) of female employees showed a positive attitude, and the study also found that female employees with a positive attitude toward menstruation-related health issues had higher HL (odds ratio (OR) = 1.216, 95% CI: 1.007-0.1.468) and were more likely to be able to predict menstruations (OR = 4.528, 95% CI: 1.618-12.670). Conclusions: In male-dominated companies, many female employees are affected by menstruation-related problems in the workplace. A positive attitude toward women's health issues was positively associated with HL and predictive ability. Male-dominated companies should pay attention to women's menstruation-related health issues in the workplace, implement interventions to improve their health literacy and predictive ability, strengthen communication with them, and encourage them to actively participate in women's health initiatives.

Abstract
OBJECTIVES Thermal therapy is used to manage various psychological diseases, such as depression. We investigated the relationship between hot spring bathing and depression in older adults using questionnaire responses. DESIGN AND SETTING We comprehensively evaluated the preventive effects of long-term hot spring bathing in 10429 adults aged ≥ 65 years in Beppu, Japan, by conducting a questionnaire study on the prevalence of depression (n = 219). MAIN OUTCOME MEASURES Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using a multivariable logistic regression model for history of depression. RESULTS A separate multivariable logistic regression model for inference showed that female sex (OR, 1.56; 95 % CI, 1.17-2.08; p = 0.002), arrhythmia (OR, 1.73; 95 % CI, 1.18-2.52; p = 0.004), hyperlipidemia (OR, 1.63; 95 % CI, 1.14-2.32; p = 0.006), renal disease (OR, 2.26; 95 % CI, 1.36-3.75; p = 0.001), collagen disease (OR, 2.72; 95 % CI, 1.48-5.02; p = 0.001), allergy (OR, 1.97; 95 % CI, 1.27-3.04; p = 0.002), and habitual daily hot spring bathing (OR, 0.63; 95 % CI, 0.41-0.94; p = 0.027) were independently significantly associated with a history of depression. CONCLUSIONS We found an inverse relationship between habitual daily hot spring bathing and history of depression. Prospective randomized controlled trials on habitual daily hot spring bathing as a treatment for depression are warranted to investigate whether the use of hot springs can provide relief to those with psychiatric and mental health disorders.

Abstract
Breast cancer is the most commonly diagnosed female cancer and the leading cause of cancer death. Early detection and treatment are important to reduce the number of deaths. Japan recommends mammography every two years for women over 40 years of age. However, in recent years, an increasing number of younger women have been undergoing breast cancer screening (BCS). To reduce the harms of BCS among young adults, our study extracted data from an online survey conducted in 2018 and applied χ2 tests and logistic analysis to identify the influencing factors regarding interest in undergoing BCS. The results of our analysis support the need for a reduction in the BCS rate through awareness regarding the harms of health screening among young people. In particular, for those who receive BCS through occupational screening, we believe that improving education on breast awareness, the accuracy of occupational screening, and breast self-examination methods could reduce the harms from BCS in younger age groups.

Abstract
OBJECTIVE The study aimed to examine life situations and perceptions related to the recognition of mutual support among Japanese people. DESIGN A quantitative, correlational, cross-sectional analysis. SAMPLE Nine hundred and nine participants who provided complete questionnaire responses. MEASUREMENTS As a disaster prevention measure, a community center conducted a "questionnaire survey evaluating the recognition of mutual support and several potentially related factors". In our study, these data from a self-administered questionnaire were used secondarily. RESULTS The perceptions that differed with regard to the sense of mutual support included family structure; satisfaction with support, security, and disaster prevention in the district; being able to ask for help with shopping; closeness of the relationship with one's neighbors; seeing oneself as providing or needing protection; and recognition of existing worries regarding evacuation. In a logistic regression model, the factors predicting the sense of mutual support included being younger than 70 years, being able to ask for help with shopping, and the closeness of the association with one's neighbors. CONCLUSIONS The study identified situations that might predict the sense of mutual support in individuals in Japanese communities.

Abstract
In Japan, healthcare workers (HCWs) are vaccinated against measles, rubella, chickenpox, mumps, and hepatitis B to prevent nosocomial infection; however, some do not produce sufficient antibodies ("suboptimal responders"). This study compared immune responses to a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 mRNA) vaccine among HCWs with normal and suboptimal responses to conventional vaccines. In this prospective cohort study, 50 HCWs received two doses of BNT162b2 mRNA vaccine 3 weeks apart. SARS-CoV-2 anti-spike antibodies were measured 11 times, starting before the first vaccination and ending 5 months after the second vaccination. Antibody titers of four suboptimal and 46 normal responders were compared. SARS-CoV-2 neutralizing antibody activity was measured twice in suboptimal responders, 1 week/1 month and 5 months after the second vaccination. The SARS-CoV-2 anti-spike antibody was detectable in the samples from suboptimal and normal responders at each timepoint after vaccination. Suboptimal responders exhibited SARS-CoV-2 neutralizing antibody activity 1 week/1 month as well as 5 months after the second vaccination; however, activity was slightly reduced at 5 months. Our findings show that suboptimal responders do acquire adequate SARS-CoV-2 anti-spike and SARS-CoV-2 neutralizing antibodies from vaccination to prevent SARS-CoV-2. SARS-CoV-2 mRNA vaccines should thus be recommended for both normal and suboptimal responders to conventional vaccines.

Abstract
Changes in serum cholesterol levels during childhood may affect the risk of cardiovascular disease in adulthood. However, cholesterol level changes in Japanese children and adolescents and the factors that influence them have not been completely elucidated. This study aimed to determine whether cholesterol levels changed due to the effects of growth and identify factors. This cohort study included elementary-school children in the fourth grade (9−10-year-old) who underwent assessments of cholesterol levels and demographic and lifestyle characteristics. The participants were followed up in their first year of junior high school with the same laboratory, demographic, and lifestyle assessments. From the fourth year of elementary school to the first year of junior high school, children’s cholesterol levels decreased (p < 0.0001). Regarding bowel movements, cholesterol level reduction was significant in individuals with regular bowel movements but not significant in those with infrequent bowel movements. Weight was the factor that most strongly negatively predicted cholesterol level reduction (p < 0.001). The study demonstrated the significance of lifestyle factors for growth-related changes of total cholesterol levels and identified weight as the factor that most strongly influenced total cholesterol level changes. Guidance regarding lifestyle improvements should be imparted to children from the fourth grade of elementary school.

Abstract
The local economy is often supported by small and medium-sized enterprises. There is a need to consider effective promotion methods for mental health measures in these enterprises in depopulated mountainous areas. It is important to understand managers' awareness when considering effective mental health measures in these enterprises. The study's aim is to explore managers' awareness of mental health measures for employees in small and medium-sized enterprises in depopulated mountainous areas in Japan.Qualitative semi-structured interviews were conducted with 6 managers in 2019. The primary issues addressed by the interview were regarding the awareness among managers about mental health promotion measures for employees. These are the primary prevention measures. The interview also addressed issues related to the awareness of measures for mental health problems that are fundamental to the secondary and tertiary prevention measures. A qualitative descriptive analysis was conducted.Three categories and 8 subcategories emerged regarding the managers' awareness of mental health promotion measures for employees. The 3 categories were: "Individual support, including their life's aspect, while taking advantage of formal and informal relationships," "The difficulty of drawing out an employees' motivation to work, due to the changes over time in the work size or in their working relationships," and "Creating a comfortable working environment for employees, by complying with the labor standards and adjusting relationships." Regarding managers' awareness of the measures for mental health problems, four categories and 8 subcategories emerged. The 4 categories were: "Prevention and awareness of the incidence of mental health problems," "Individual support based on the enterprise's or employee's characteristics," "A lack of support for the manager to address employees' mental health problems," and "Employees quitting the job, due to the lack of appropriate support."Though managers in depopulated mountainous areas were well aware of the mental health activities offered, the categories showed the need to foster social capital. It also showed the need to collaborate with external support organizations, and the difficulties faced by small and medium-sized enterprises.

Abstract
Background: Accumulation of adipose tissue progresses to metabolic diseases. Sonography is a convenient modality for measuring the thickness of adipose tissue. The present study aimed to clarify the site of adipose tissue thickness that correlated best with laboratory test values reflecting metabolic abnormalities. Methods: Subjects comprised 37 elderly women with metabolic diseases or an almost healthy state (median age, 71 years; interquartile range, 62-78 years). Abdominal visceral adipose tissue (VAT), subcutaneous adipose tissue, peritoneal adipose tissue, perirenal adipose tissue, and epicardial adipose tissue (EAT) thicknesses were measured. Correlations were evaluated between laboratory test values and these adipose tissue thicknesses. Results: VAT thickness measured at the level of the umbilicus correlated positively with values of triglycerides (TGs) (r = 0.593, P = 0.0009) and hemoglobin A1c (r = 0.490, P = 0.0081) and negatively with the value of high-density lipoprotein cholesterol (r = -0.521, P = 0.0045), even after adjusting for body mass index. Significant positive correlations were also found between EAT thickness and TGs (r = 0.542, P = 0.0029). Conclusions: Among the adipose tissue thicknesses measured at several sites by sonography, VAT thickness correlated most closely with laboratory test values representing metabolic abnormalities in elderly women.

Abstract
It is well known that black and green tea extracts, particularly polyphenols, have antimicrobial activity against various pathogenic microbes including viruses. However, there is limited data on the antiviral activity against severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), which emerged rapidly in China in late 2019 and which has been responsible for coronavirus disease 2019 (COVID‐19) pandemic globally. In this study, 20 compounds and three extracts were obtained from black and green tea and found that three tea extracts showed significant antiviral activity against SARS‐CoV‐2, whereby the viral titre decreased about 5 logs TCID50 per ml by 1·375 mg ml−1 black tea extract and two‐fold diluted tea bag infusion obtained from black tea when incubated at 25°C for 10 s. However, when concentrations of black and green tea extracts were equally adjusted to 344 µg ml−1, green tea extracts showed more antiviral activity against SARS‐CoV‐2. This simple and highly respected beverage may be a cheap and widely acceptable means to reduce SARS‐CoV‐2 viral burden in the mouth and upper gastrointestinal and respiratory tracts in developed as well as developing countries.

Abstract
Background Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), the causative agent of the coronavirus disease 2019 (COVID‐19), is detected using real‐time RT‐PCR. However, there are limitations pertaining to quality control, particularly with respect to establishing quality control measures for extraction of viral nucleic acids. Here, we investigated the quality control measures for the various processes using an extrinsic quality control substance and quality control charts. Methods An extrinsic quality control substance was added to the sample, and then, real‐time RT‐PCR was performed. Samples with negative test results and the corresponding data were analyzed; a quality control chart was created and examined. Results Data analysis and the quality control charts indicated that SARS‐CoV‐2 could be reliably detected using real‐time RT‐PCR, even when different nucleic acid extraction methods were used or when different technicians were employed. Conclusion With the use of quality control substances, it is possible to achieve quality control throughout the process—from nucleic acid extraction to nucleic acid detection—even upon using varying extraction methods. Further, generating quality control charts would guarantee the stable detection of SARS‐CoV‐2.

Abstract
BACKGROUND A new coronavirus (SARS-CoV-2) abruptly emerged in Wuhan, China, in 2019 and rapidly spread globally to cause the COVID-19 pandemic. AIM To examine the anti-SARS-CoV-2 activity of the potent disinfectant Cleverin, the major disinfecting component of which is chlorine dioxide (ClO2); and to compare the results with that of sodium hypochlorite in the presence or absence of 0.5% or 1.0% foetal bovine serum (FBS). METHODS Concentrated SARS-CoV-2 viruses were treated with various concentrations of ClO2 and sodium hypochlorite and 50% tissue culture infective dose was calcurated to evaluate the antiviral activity of each chemical. FINDINGS When SARS-CoV-2 viruses were treated with 0.8 ppm ClO2 or sodium hypochlorite, viral titre was decreased only by 1 log10 TCID50/mL in 3 min. However, the viral titre was decreased by more than 4 log10 TCID50/mL when treated with 80 ppm of each chemical for 10 s regardless of presence or absence of FBS. It should be emphasized that treatment with 24 ppm of ClO2 inactivated more than 99.99% SARS-CoV-2 within 10 s or 99.99% SARS-CoV-2 in 1 min in the presence of 0.5% or 1.0% FBS, respectively. By contrast, 24 ppm of sodium hypochlorite inactivated only 99% or 90% SARS-CoV-2 in 3 min under similar conditions. Notably, except for ClO2, the other components of Cleverin such as sodium chlorite, decaglycerol monolaurate, and silicone showed no significant antiviral activity. CONCLUSION Altogether, the results strongly suggest that although ClO2 and sodium hypochlorite are strong antiviral agents in absence of organic matter but in presence of organic matter, ClO2 is a more potent antiviral agent against SARS-CoV-2 than sodium hypochlorite.

Abstract
There is a need to comprehensively identify depression-related factors, including individual and socioeconomic factors, in each country or cultural area, to consider effective measures to address depression within communities. However, there are not enough studies on middle-aged residents in Japan or other Eastern countries to currently achieve this. Thus, the aim of this study was to comprehensively identify factors related to depression in middle-aged residents in Japan, an Eastern country.The study design was cross-sectional. A questionnaire survey was conducted among all community residents aged 40 to 59 in a rural municipality in Western Japan. The questionnaire contained items on demographic characteristics, psychological factors, health-related behaviors, and socioeconomic factors. A Chi-Squared test or Fisher exact test was used to analyze the relationships between depression and each assessed factor. Next, a logistic regression analysis was performed to identify comprehensive relationships between depression and its related factors.Data from 362 participants were analyzed. The average age was 51.5 years; 148 were male. A Chi-Squared test or Fisher exact test demonstrated that many psychological factors, health-related behaviors, and socioeconomic factors ware significantly related to depression. A logistic regression analysis showed that depression was significantly associated with male gender, low sense of coherence, high cognitive stress levels, low help-seeking behavior, poor quality sleep, and a lack of hobbies. Nagelkerke R2 was 51%.This study revealed through multivariate analysis that depression was primarily associated with personal behavioral and psychological factors in Japan, an Eastern country with a holistic cultural background. This result is consistent with findings from Western countries. This study can contribute the promotion and evaluation of preventive measures for depression in Eastern culture that focus on individual behavioral and psychological factors.

Abstract
BACKGROUND/AIMS The present study was performed to compare the safety of sedation with propofol during endoscopic submucosal dissection (ESD) for gastric tumors under sedation in the endoscopy room by an endoscopist versus sedation in the operation room by an anesthesiologist. METHODS In total, 638 patients with gastric tumors who underwent ESD from January 2011 to August 2017 at Ureshino Medical Center and Saga Medical Center Koseikan were retrospectively reviewed. The patients were divided into 2 groups: those who underwent ESD in the endoscopy room (Group E, n = 532) and those who underwent ESD in the operation room (Group O, n = 106). Propensity score matching was applied for evaluation. The treatment outcome of ESD and the adverse events of sedation during ESD (desaturation, hypotension, bradycardia, and arrhythmia) were compared between the 2 groups to consider the safety of ESD. RESULTS The propensity score-matching analysis created 82 matched pairs. Adjusted comparisons between Groups E and O showed similar treatment outcomes of ESD for gastric tumors. There were no significant differences in the treatment outcomes, anesthesia time, and mean propofol dose between the 2 groups. With respect to adverse events, desaturation occurred more often in Group E than Group O (18.3 vs. 3.7%, respectively; p = 0.005). There were no significant differences in other adverse events (hypotension, bradycardia, and arrhythmia) between the 2 groups. CONCLUSION Sedation with propofol in the operation room might be required to ensure safer application of ESD for gastric tumors. However, a decrease in the desaturation rate was the only disadvantage of sedation in the endoscopy room.

Abstract
Background: Type A behavior pattern has been presented as a risk for coronary heart disease and defined as a psychological-behavioral construct. This study aimed to identify the influence of type A behavior pattern on blood pressure in the current cultural context of Japan. Methods: This study utilized a cross-sectional design. Self-administered questionnaires were distributed to community residents aged 40–59 yr in western Japan from Aug to Sep 2017. The data included participant’s demographic information (including socioeconomic variables); information related to blood pressure, type A behavior pattern, psychological factors, and health-related behaviors. Logistic regression was used to identify the influence of type A behavior pattern on systolic blood pressure after adjusting for behavioral, psychological, and socioeconomic factors. Results: The sample included 362 participants with a mean age of 51.5 years (SD = 5.96); 148 (41.2%) men. A logistic regression demonstrated that type A behavior pattern was negatively associated with systolic blood pressure (OR = 0.43, 95% CI [0.22, 0.83]) after adjusting for sex and age. Similar results were observed after adjusting for other covariates. Conclusion: There may be a negative association between type A behavior pattern and systolic blood pressure among adults living in the current cultural context of Japan.

Abstract
Universities have quickly shifted to remote learning due to the COVID-19 pandemic. This study compared two versions-emergency remote teaching (ERT) and conventional face-to-face class (FFC)-of a course design based on the instructional design ARCS model for effectiveness and issues. The current study comprised 46 third-year nursing students who attended an FFC course in 2019, and 56 third-year students who took the ERT version in 2020. Students' self-rated goal attainment and knowledge of genetics scores were compared before and after taking the courses. Scores between the two class types were compared using the Wilcoxon rank sum test. The students' worksheets were evaluated using keyword frequency and content analyses. Both classes achieved their goals satisfactorily, and this study confirmed that for this course, ERT was as effective as FFC. A comparison of the increase in domain goal attainment scores per student showed that only the psychomotor domain item, "I can fully explain human diversity using genomic information", was significantly different, as it was significantly higher for ERT (p = 0.003). This higher item in the ERT group suggests that ERT can pose a lack of practice caution in acquiring nursing skills.

Abstract
After the 2011 Fukushima Daiichi accident, demands regarding nursing staff's management of nuclear disasters have increased. This study aimed to evaluate a basic training program to teach undergraduate nursing students on how to deal with public anxiety following a nuclear disaster. We analyzed the data of 111 third-year nursing students attending a Japanese university. We set attainment goals in three domains (cognitive, affective, psychomotor) regarding their acquisition of consultation techniques for radiation-related health concerns. We compared pre- and post-class response scores on a knowledge test and calculated word frequencies in health consultation scenarios. The pre-class mean score was 12.2 out of 27 points and the post-class mean score (directly after the course) was 21.0, a significant increase (p < 0.001). The mean level of attainment in each of the three domains increased significantly from pre-test to post-test (p < 0.001). The variety and number of words in the health consultations also increased. Students attained the program goals for radiation-related health concerns in all domains. During disasters, there is a great need for nursing staff to administer physical and mental care to the public. This program was evaluated to be one wherein nursing staff can acquire fundamental knowledge about radiation in a short time.

Abstract
PURPOSE Well-differentiated liposarcoma, the most common subtype of liposarcoma, should be discriminated from benign lipoma. However, features on sonography for discriminating these two types of tumor have not been fully investigated. The present study was therefore aimed at clarifying differences in sonographic findings between well-differentiated liposarcoma and lipoma. METHODS The study population comprised 23 cases of well-differentiated liposarcoma and 181 cases of lipoma. We investigated differences in sonographic appearance and pathological findings between the two types of tumor. RESULTS Well-differentiated liposarcoma tended to develop more frequently in older patients and in the lower extremities including the gluteal region, compared with lipoma. Concerning sonographic findings, both tumors exhibited well-defined margins and heterogeneous internal echogenicity, including typical tiny striated hyperechoic lines. Well-differentiated liposarcoma was characterized by a higher frequency of the following findings compared with lipoma: (1) deep location, (2) irregular shape, (3) large diameter, (4) hyperechogenicity compared to surrounding tissue, and (5) presence of vascularity on Doppler sonography (p < 0.01 each). Notably, hyperechogenicity corresponded to the intermingled sclerosing component within the adipocytic component when sonographic findings were compared with those of pathology. CONCLUSION The present study suggests that several sonographic findings including hyperechogenicity and presence of vascularity might be key features for discriminating well-differentiated liposarcoma from lipoma.

Abstract
BACKGROUND Leukocyte removal therapy (LRT) is an effective treatment for active ulcerative colitis (UC). The present study was performed to evaluate the relapse-free period after LRT and identify risk factors for relapse. METHODS In total, 94 patients who underwent first-time LRT for remission of moderate to severe UC from April 2004 to March 2016 were enrolled in the present study. The patients were randomly assigned to one of 2 treatments: leukocytapheresis (LCAP; n = 43) or granulocyte and monocyte/macrophage adsorptive apheresis (GMA; n = 51). The 5-year cumulative relapse-free rate and risk factors for relapse were evaluated. RESULTS The therapeutic response rate was 82% for GMA and 70% for LCAP without a statistically significant difference. The 5-year relapse-free rate was 34.7% in the LRT group. The 5-year relapse-free rate in patients aged > 40 years was 49.9%, which was significantly higher than that in patients aged ≤40 years (22.9%, p < 0.01). The relapse-free period was longer in the older than younger patients. CONCLUSIONS The relapse-free period after LRT was examined in patients with UC, and 34.7% of patients achieved clinical remission within a 5-year period. The risk factor for early relapse after LRT was younger age.

Abstract
Diamond has two crystallographically inequivalent sites in the unit cell. In doped diamond, dopant occupation in the two sites is expected to be equal. Nevertheless, preferential dopant occupation during growth under nonequilibrium conditions is of fundamental importance, for example, to enhance the properties of nitrogen-vacancy (N-V) centers; therefore, this is a promising candidate for a qubit. However, the lack of suitable experimental techniques has made it difficult to study the crystal- and chemical-site-resolved local structures of dopants. Here, we confirm the identity of two chemical sites with asymmetric dopant incorporation in the diamond structure, via the photoelectron holography (PEH) of heavily phosphorus (P)-doped diamond prepared by chemical vapor deposition. One is substitutionally incorporated P with preferential site occupations and the other can be attributed to a PV split vacancy complex with preferential orientation. The present study shows that PEH is a valuable technique to study the local structures around dopants with a resolution of crystallographically inequivalent but energetically equivalent sites/orientations. Such information provides strategies to improve the properties of dopant related-complexes in which alignment is crucial for sensing of magnetic field or quantum spin register using N-V centers in diamond.

Abstract
Liposarcoma is the second most common malignant soft-tissue tumor. This entity is pathologically categorized into 4 subtypes: well-differentiated, myxoid, dedifferentiated and pleomorphic. Although features on magnetic resonance imaging and computed tomography for these 4 subtypes have been reported quite precisely, those on sonography have not been fully investigated. The present study was therefore aimed at clarifying the sonographic appearances of each liposarcoma subtype and assessing correlations with histopathology. The study population was made up of 35 cases, including 21 cases of well-differentiated liposarcoma, 6 cases of myxoid liposarcoma, 6 cases of dedifferentiated liposarcoma and 2 cases of pleomorphic liposarcoma. Compared with the other subtypes, well-differentiated liposarcoma was characterized by the high frequency of the following findings: isoechogenicity, tiny hyperechoic lines and hypovascularity (p < 0.01, in each). Myxoid liposarcomas were characterized by low echogenicity, intermingled with anechoic areas and moderate vascularity (p < 0.01, in each). Dedifferentiated liposarcomas showed a specific biphasic pattern of hyperechoic and hypoechoic areas and hypervascularity (p < 0.01, in each). Pleomorphic liposarcomas showed a specific gyrus-like mixture of hyperechoic and hypoechoic areas (p < 0.01). In conclusion, the present study revealed different characteristics of sonographic appearance among the 4 histopathologic subtypes of liposarcoma.

Abstract
Acute kidney injury (AKI) is associated with poor prognosis among patients with acute heart failure (AHF). Early documentation of impaired kidney function through simple examination may provide risk reduction in such patients. The present study aims to reveal an association between cellular casts and hospital-acquired AKI in AHF. This study included patients with AHF who underwent urinalysis, including urinary sediment analysis within 24 hours post admission. AKI was defined as an increase of ≥0.3 mg/dL within 48 hours or ≥1.5 times in serum creatinine level in contrast to baseline creatinine level. In this study, 114 patients with AHF (age, 75 ± 14 years; male, 59.7%) were included. Of them, 40 (35%) developed hospital-acquired AKI. Cellular casts were detected in 30 patients (26%) prior to AKI development and related to hospital-acquired AKI in the multivariate logistic regression analysis (odds ratio, 2.80; 95% confidence interval, 1.04–7.49; P = 0.041). In conclusion, cellular casts are observed occasionally in patients with AHF and potentially useful markers for development of AKI during hospitalization.

Abstract
RNA-binding proteins (RBPs) regulate mRNA stability by binding to the 3'-untranslated region (UTR) region of mRNA. Human antigen-R (HuR), one of the RBPs, is involved in the progression of diseases, such as rheumatoid arthritis, diabetes mellitus and some inflammatory diseases. Interleukin (IL)-6 is a major inflammatory cytokine regulated by HuR binding to mRNA. Periodontal disease (PD) is also an inflammatory disease caused by elevations in IL-6 following an infection by periodontopathogenic bacteria. The involvement of HuR in the progression of PD was assessed using in-vitro and in-vivo experiments. Immunohistochemistry of inflamed periodontal tissue showed strong staining of HuR in the epithelium and connective tissue. HuR mRNA and protein level was increased following stimulation with Porphyromonas gingivalis (Pg), one of the periodontopathogenic bacteria, lipopolysacchride (LPS)-derived from Pg (PgLPS) and tumour necrosis factor (TNF)-α in OBA-9, an immortalized human gingival epithelial cell. The luciferase activity of 3'-UTR of IL-6 mRNA was increased by TNF-α, Pg and PgLPS in OBA-9. Luciferase activity was also increased in HuR-over-expressing OBA-9 following a bacterial stimulation. Down-regulation of HuR by siRNA resulted in a decrease in mRNA expression and production of IL-6. In contrast, the over-expression of HuR increased IL-6 mRNA expression and production in OBA-9. The HuR inhibitor, quercetin, suppressed Pg-induced HuR mRNA expression and IL-6 production in OBA-9. An oral inoculation with quercetin also inhibited bone resorption in ligature-induced periodontitis model mice as a result of down-regulation of IL-6. These results show that HuR modulates inflammatory responses by regulating IL-6.

Abstract
Calcineurin inhibitors (CNIs) have been used off-label for the treatment of refractory Kawasaki disease (KD). However, it remains unknown whether CNIs show protective effects against the development of coronary artery lesions in KD patients. To investigate the effects of CNIs on coronary arteries and the mechanisms of their actions on coronary arteritis in a mouse model of KD, we performed experiments with FK565, a ligand of nucleotide-binding oligomerization domain-containing protein 1 (NOD1) in wild-type, severe combined immunodeficiency (SCID), caspase-associated recruitment domain 9 (CARD9)-/- and myeloid differentiation primary response gene 88 (MyD88)-/- mice. We also performed in-vitro studies with vascular and monocytic cells and vascular tissues. A histopathological analysis showed that both cyclosporin A and tacrolimus exacerbated the NOD1-mediated coronary arteritis in a dose-dependent manner. Cyclosporin A induced the exacerbation of coronary arteritis in mice only in high doses, while tacrolimus exacerbated it within the therapeutic range in humans. Similar effects were obtained in SCID and CARD9-/- mice but not in MyD88-/- mice. CNIs enhanced the expression of adhesion molecules by endothelial cells and the cytokine secretion by monocytic cells in our KD model. These data indicated that both vascular and monocytic cells were involved in the exacerbation of coronary arteritis. Activation of MyD88-dependent inflammatory signals in both vascular cells and macrophages appears to contribute to their adverse effects. Particular attention should be paid to the development of coronary artery lesions when using CNIs to treat refractory KD.

Abstract
Adaptation to different environments can promote population divergence via natural selection even in the presence of gene flow - a phenomenon that typically occurs during ecological speciation. To elucidate how natural selection promotes and maintains population divergence during speciation, we investigated the population genetic structure, degree of gene flow and heterogeneous genomic divergence in three closely related Japanese phytophagous ladybird beetles: Henosepilachna pustulosa, H. niponica and H. yasutomii. These species act as a generalist, a wild thistle (Cirsium spp.) specialist and a blue cohosh (Caulophyllum robustum) specialist, respectively, and their ranges differ accordingly. The two specialist species widely co-occur but are reproductively isolated solely due to their high specialization to a particular host plant. Genomewide amplified fragment-length polymorphism (AFLP) markers and mitochondrial cytochrome c oxidase subunit I (COI) gene sequences demonstrated obvious genomewide divergence associated with both geographic distance and ecological divergence. However, a hybridization assessment for both AFLP loci and the mitochondrial sequences revealed a certain degree of unidirectional gene flow between the two sympatric specialist species. Principal coordinates analysis (PCoA) based on all of the variable AFLP loci demonstrated that there are genetic similarities between populations from adjacent localities irrespective of the species (i.e. host range). However, a further comparative genome scan identified a few fractions of loci representing approximately 1% of all loci as different host-associated outliers. These results suggest that these three species had a complex origin, which could be obscured by current gene flow, and that ecological divergence can be maintained with only a small fraction of the genome is related to different host use even when there is a certain degree of gene flow between sympatric species pairs.

Abstract
AIMS To investigate the virulence of the Vp_PirAB-like genes in Vibrio parahaemolyticus- acute hepatopancreatic necrosis disease (AHPND)-causing strain and the factors that are associated with the virulence level. METHODS AND RESULTS The virulence of Vp_PirAB-like was examined using a non-virulent strain FP11 of V. parahaemolyticus transformed with a plasmid harbouring Vp_PirAB-like genes and then it was used to challenge shrimp Litopenaeus vannamei and Marsupenaeus japonicus. Both species experienced 100% mortality at 10 days post infection. Analysis of a mutant strain (E1M), that was originally identified as virulent strain (E1) but lost its virulence to L. vannamei, revealed that it lacked a part of the Vp_PirA-like gene and all of the Vp_PirB-like gene. The copy numbers of Vp_PirA-like and Vp_PirB-like genes varied among virulent strains and were not correlated with their virulence. In Western blotting, Vp_PirA-like and Vp_PirB-like proteins were detected in both the cell lysate and the culture supernatant. The strongest intensity of detecting band in the culture supernatant was observed in the strain that caused the highest mortality. The V. parahaemolyticus AHPND-causing strain, unlike the human tdh-positive strain, did not show any enterotoxicity. CONCLUSION Vibrio parahaemolyticus AHPND-causing strains secrete the Vp_PirA-like and Vp_PirB-like proteins during the growing phase. The amount of secreted proteins affects the shrimp mortality. SIGNIFICANCE AND IMPACT OF THE STUDY The secreted proteins of Vp_PirAB-like are key factors of virulence in the V. parahaemolyticus AHPND-causing strain, but not gene copy.

Abstract
Kawasaki disease (KD) is an acute systemic vasculitis of childhood that does not have a known cause or aetiology. The epidemiological features (existence of epidemics, community outbreaks and seasonality), unique age distribution and clinical symptoms and signs of KD suggest that the disease is caused by one or more infectious environmental triggers. However, KD is not transmitted person-to-person and does not occur in clusters within households, schools or nurseries. KD is a self-limited illness that is not associated with the production of autoantibodies or the deposition of immune complexes, and it rarely recurs. Regarding the underlying pathophysiology of KD, innate immune activity (the inflammasome) is believed to play a role in the development of KD vasculitis, based on the results of studies with animal models and the clinical and laboratory findings of KD patients. Animal studies have demonstrated that innate immune pathogen-associated molecular patterns (PAMPs) can cause vasculitis independently of acquired immunity and have provided valuable insights regarding the underlying mechanisms of this phenomenon. To validate this concept, we recently searched for KD-specific PAMPs and identified such molecules with high specificity and sensitivity. These molecules have structures similar to those of microbe-associated molecular patterns (MAMPs), as shown by liquid chromatography-tandem mass spectrometry. We propose herein that KD is an innate immune disorder resulting from the exposure of a genetically predisposed individual to microbe-derived innate immune stimulants and that it is not a typical infectious disease.

Abstract
Emergent superselective embolization with a 3.0 F (1 mm) coaxial catheter and a steerable guidewire was performed in 27 patients with massive hemorrhage from a small-caliber splanchnic artery. Eight patients had intraperitoneal hemorrhage, 3 had hemobilia, 9 had gastric hemorrhage, and 7 had intestinal hemorrhage. Out of 27 patients, 7 had hemorrhage from a splanchnic artery pseudoaneurysm. Complete cessation of bleeding was obtained in all patients initially, but in 3 patients gastric hemorrhage recurred later. Otherwise, there was no rebleeding nor any major complication such as marked infarction of tissue or misplacement of embolic materials. This coaxial catheter system was highly reliable for achieving superselective catheterization in small-caliber arteries, minimizing the volume of infarcted tissue and allowing maximal preservation of splanchnic organic function. We conclude that this system represents a major advance in interventional radiology.

Abstract
Epidemiological studies have linked periodontitis to rheumatoid arthritis (RA). Porphyromonas gingivalis (Pg) was reported recently to produce citrullinated protein (CP) and increase anti-cyclic CP antibody (ACPA), both of which have been identified as causative factors of RA. In the present study, we determined the effects of Pg infection on the exacerbation of RA in a mouse model. RA model mice (SKG mice) were established by an intraperitoneal (i.p.) injection of laminarin (LA). Mice were divided into six groups, Ctrl (PBS injection), LA (LA injection), Pg/LA (Pg + LA injection), Pg (Pg injection), Ec/LA (Escherichia coli and LA injection) and Ec (E. coli injection). In order to evaluate RA, joint swelling by the arthritis score, bone morphology by microcomputed tomography (microCT), haematoxylin and eosin staining, ACPA, matrix metalloproteinase-3 (MMP-3) and cytokine level in serum by enzyme-linked immunosorbent assay were determined. Osteoclast differentiation from bone marrow mononuclear cells (BMCs) was examined to clarify the underlying mechanisms of RA. The presence of Pg and CP in joint tissue was also investigated. The arthritis score was threefold higher in the Pg/LA group than in the LA group. Severe bone destruction was observed in joint tissue of the Pg/LA group. A microCT analysis of the Pg/LA group revealed a decrease in bone density. ACPA, MMP-3, interleukin (IL)-2, IL-6, CXCL1 and macrophage inflammatory protein (MIP)-1α levels from the Pg/LA group were the highest. The osteoclastogenesis of BMCs was enhanced in the Pg/LA group. Furthermore, large amounts of Pg components and CP were detected in the Pg/LA group. In conclusion, Pg infection has the potential to exacerbate RA.

Abstract
In recent years, millisecond-duration radio signals originating in distant galaxies appear to have been discovered in the so-called fast radio bursts. These signals are dispersed according to a precise physical law and this dispersion is a key observable quantity, which, in tandem with a redshift measurement, can be used for fundamental physical investigations. Every fast radio burst has a dispersion measurement, but none before now have had a redshift measurement, because of the difficulty in pinpointing their celestial coordinates. Here we report the discovery of a fast radio burst and the identification of a fading radio transient lasting ~6 days after the event, which we use to identify the host galaxy; we measure the galaxy's redshift to be z = 0.492 ± 0.008. The dispersion measure and redshift, in combination, provide a direct measurement of the cosmic density of ionized baryons in the intergalactic medium of ΩIGM = 4.9 ± 1.3 per cent, in agreement with the expectation from the Wilkinson Microwave Anisotropy Probe, and including all of the so-called 'missing baryons'. The ~6-day radio transient is largely consistent with the radio afterglow of a short γ-ray burst, and its existence and timescale do not support progenitor models such as giant pulses from pulsars, and supernovae. This contrasts with the interpretation of another recently discovered fast radio burst, suggesting that there are at least two classes of bursts.

Abstract
Abstract We report two cases of rheumatoid arthritis (RA) with atypical mycobacteriosis. Opportunistic infections are critical complications for rheumatic diseases. The use of steroids or immunosuppressants may increase the risk of opportunistic infections. However, these reports are rare in that they demonstrate atypical mycobacterial infections as complications of RA, even though no immunosuppressive agents were used. We discuss the characteristics of atypical mycobacterial infections of the lung in RA.
