In the early days of hygiene science in Japan, the results of nutritional epidemiology research by Dr. Kanehiro Takaki, a naval doctor who studied medicine in Kagoshima, on the prevention of beriberi, a national disease at the time, were highly regarded internationally. Since then, hygiene research on food ingredients has been vigorously pursued to expand from basic research to applied research, as exemplified by the development of the allithiamine. The symposium \"Food Ingredients and Hygiene: Exploring the Functions of Food Ingredients from Hygiene\" was organized by the Young Researchers Association at the 94th Annual Meeting of the Japanese Society for Hygiene (Kagoshima) to introduce recent research and examples of industry-academia collaboration. Young researchers involved in hygiene research on foods and food materials presented their recent work ranging from basic research, such as the functional evaluation of foods by animal experiments and the evaluation of the effects of polyphenols and yogurt on health, which have long been studied, to applied research leading to the commercialization of foods with useful physiological effects. This mini-review is a summary of the symposium. As the Young Researchers Association, we hope that this symposium/mini-review will encourage young researchers to become interested in various functions of food ingredients, conduct related research, and consider how to contribute their research results to society.","PeriodicalId":35643,"journal":{"name":"Japanese Journal of Hygiene","volume":"80 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143459932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This denotes that light drinking has a preventive effect on cardiovascular diseases. Effects of alcohol drinking on lipid metabolism including an increase in HDL cholesterol concentration and a decrease in LDL cholesterol concentration are the main reasons for the anti-atherosclerotic action of alcohol. The antithrombotic effect of alcohol through the inhibition of platelet function is also involved in the lower incidence of ischemic arterial disease in drinkers. Capacitative Ca2+ entry, a main mechanism for platelet aggregation, is inhibited by ethanol. Ethanol also inhibits plasmalemmal phospholipase A2 activity and consequent thromboxane A2 production. French paradox is a phenomenon showing the merit of red wine consumption for the prevention of ischemic heart disease. In addition to ethanol, red wine contains anti-oxidative polyphenol compounds, represented by resveratrol, which has an antiplatelet action. Resveratrol also inhibits the capacitative Ca2+ entry in platelets. Furthermore, ethanol and resveratrol show a synergic inhibitory action on platelet aggregation, which may be caused by the reduction in the Ca2+ sensitivity of the contractile apparatus of platelets and the attenuation of COX-1 activity. Thus, the strength of the antithrombotic action is thought to differ depending on alcohol beverage. Decreases in concentrations of coagulation factors including fibrinogen are also involved in the alcohol-induced antithrombotic action. Alcohol drinking causes hemorrhagic diathesis as well as antithrombotic tendency.","PeriodicalId":35643,"journal":{"name":"Japanese Journal of Hygiene","volume":"79 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142781394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The PEMSQ-J was the main instrument used to collect information such as basic demographics.Cronbach's α was calculated to determine internal consistency, and the intraclass correlation coefficient was calculated to assess reproducibility. In addition, confirmatory factor analysis with covariance structure analysis was performed to confirm the goodness of fit of the model. Finally, criterion-related validity was confirmed.Results: Analysis of responses to items on the PEMSQ-J revealed no ceiling or floor effects, and there was no marked bias in distributions in terms of skewness or kurtosis. Internal consistency assessed with Cronbach's α ranged from 0.847 to 0.935. A test of reproducibility revealed that the intraclass correlation for the total score was 0.730. Exploratory factor analysis identified two factors, which differed from the four factors in the original version. When their details and structure were examined, however, the two were interpreted as having a similar structure. Similarly to those of the original version, the goodness-of-fit indices for the four factors according to confirmatory factor analysis were close to the standard values.Conclusion: The PEMSQ-J, which consists of 27 items with a four-factor structure, was statistically acceptable, and it was found to have a certain degree of reliability and validity.","PeriodicalId":35643,"journal":{"name":"Japanese Journal of Hygiene","volume":"79 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142548014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been reported that visually induced motion sickness (VIMS) is more frequently caused by viewing these images. We propose a method to control VIMS by controlling visually evoked postural responses (VEPRs) using galvanic vestibular stimulation (GVS). In this study, we focused on the effect of VEPRs on body sway and conducted a transfer function analysis between the GVS and body sway. On the basis of the results of this investigation of the causes of VIMS, countermeasures must be considered.Methods: The experiment involved 15 healthy young adults, comprising six males and nine females, all aged 21 years. The subjects were asked to maintain a Romberg posture while viewing an image that included a large number of randomly positioned moving spheres with their peripheral vision. In addition, body sway during GVS as an external stimulus was measured for 120s for each task.Results: The transfer function analysis of the body sway showed that the influence on the equilibrium function was significantly enhanced not only by the GVS but even more so by viewing the video clips synchronized to the GVS.Conclusions: GVS current signals induced body sway and increased the width of body sway synergistically. It was also suggested that a time delay structure occurred between the GVS current signal and body sway.","PeriodicalId":35643,"journal":{"name":"Japanese Journal of Hygiene","volume":"79 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142781395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The HL scale we previously developed was slightly modified on the basis of the pre-examination and used for developing CHLS-J. Self-reported data on demographic variables, socioeconomic status, health-related behaviors, present illness, past illness, and HL were collected. To determine the factor structure of the HL scale, an exploratory factor analysis was conducted, and the internal consistency of the scale was assessed using Cronbach's coefficient alpha. The criterion-related validity was evaluated using the Pearson product-moment correlation coefficient.Results: From the results of factor analysis, 30 HL items were extracted and the structure was based on three factors (the knowledge and competencies for collecting health information, decision-making and communication, and the motivation for utilizing health information). High CHLS-J scores were significantly associated with food purchasing behaviors based on food labeling and maintaining a well-balanced diet. Furthermore, patients with present or past illness were more likely to have high CHLS-J scores.Conclusions: The results show that CHLS-J is mostly a validated and reliable scale, and that the high-HL group had a healthy eating lifestyle. This study suggests that CHLS-J can be used to measure HL and educate Japanese workers on the necessity of health behavioral changes.","PeriodicalId":35643,"journal":{"name":"Japanese Journal of Hygiene","volume":"79 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140120933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, few studies have examined the ethical review processes of these institutes.Methods: We analyzed information on (a) the status and year of establishment of \"Ethics Review Committees\" (and equivalent committees), (b) the number of review cases for each year, (c) the status of public disclosure of committee activities, and (d) the composition of committee members for 85 PHIs across Japan. Publicly available information from each PHI and the Ministry of Health, Labour and Welfare was used for the analysis.Results: Out of 85 PHIs nationwide, about half of them publicly disclosed the establishment of their committees (41 committees, 48.2%). The number of review cases handled by the committees varied, with some committees having no cases or only one case. Among the committees, approximately 20% still maintained adherence to outdated national research ethics guidelines, and approximately 15% did not specify any guidelines they followed. Furthermore, we identified committees without external members (at least two committees) and those lacking public representation (four committees).Conclusion: There are differences in the operational performance of ethics review committees at PHIs, possibly owing to varying levels of understanding of the guidelines, the degree of proactive engagement in academic research, and the emphasis on human subject research. There is a crucial need to accumulate and share experiences that support the review functions of the committees.","PeriodicalId":35643,"journal":{"name":"Japanese Journal of Hygiene","volume":"79 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142548013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
