Objective: We investigated the psychological distress of school teachers using a 6-item instrument (the K6) in Kagawa prefecture, Japan. Methods: A total of 670 school teachers (328 men and 342 women) were analyzed in this cross-sectional investigation study. The association between psychological distress and clinical factors was evaluated by using the K6 instrument, with psychological distress defined as 13 or more points out of a total of 24 points. Results: A total of 55 teachers (8.2%) were classified as having psychological distress. No significant relationships between the K6 score and sex, age, duration of experience as a teacher, school grade and title were noted. The K6 score in teachers with consciousness of suicide among students was higher than that without, but not at a significant level. Conclusion: Some teachers were defined as having psychological distress in Kagawa prefecture, Japan. However, no relevant effects of basic characteristics such as age and sex on psychological distress were recognized.

We evaluated the psychological distress using a scale of the K6, the 6-item scale of psychological distress on public health nurse in Kagawa prefecture, Japan. We send the questionnaire to all public health nurses (n = 419) in Kagawa prefecture. Then, a total of 256 public health nurses (1 man and 255 women), had completely answered the questionnaires, were analyzed in a cross-sectional investigation study. The association between psychological distress and considerable factors were evaluated by using the K6, with psychological distress defined as 13 or more points out of a total of 24 points. A total of 15 public health nurses (5.9%) were defined as psychological distress. Clear relationships between the K6 score and age, experience duration as public health nurse were not noted. The K6 score in subjects with anxiety of preventing suicide was significantly higher than that without. In addition, the K6 score in subjects who feel their own mental status was excellent was also lower than that in subjects without that. In conclusion, some factors might be associated with psychological distress, as assessed by the K6, in public health nurse in Kagawa prefecture, Japan.

The immune-stromal cell interactions play a key role in health and diseases. In periodontitis, the most prevalent infectious disease in humans, immune cells accumulate in the oral mucosa and promote bone destruction by inducing receptor activator of nuclear factor-κB ligand (RANKL) expression in osteogenic cells such as osteoblasts and periodontal ligament cells. However, the detailed mechanism underlying immune–bone cell interactions in periodontitis is not fully understood. Here, we performed single-cell RNAsequencing analysis on mouse periodontal lesions and showed that neutrophil–osteogenic cell crosstalk is involved in periodontitis-induced bone loss. The periodontal lesions displayed marked infiltration of neutrophils, and in silico analyses suggested that the neutrophils interacted with osteogenic cells through cytokine production. Among the cytokines expressed in the periodontal neutrophils, oncostatin M (OSM) potently induced RANKL expression in the primary osteoblasts, and deletion of the OSM receptor in osteogenic cells significantly ameliorated periodontitis-induced bone loss. Epigenomic data analyses identified the OSM-regulated RANKL enhancer region in osteogenic cells, and mice lacking this enhancer showed decreased periodontal bone loss while maintaining physiological bone metabolism. These findings shed light on the role of neutrophils in bone regulation during bacterial infection, highlighting the novel mechanism underlying osteoimmune crosstalk.

Oral clefts, the most frequent congenital birth defects in humans, are multifactorial disorders caused by genetic and environmental factors. Epidemiological studies point to different etiologies underlying the oral cleft phenotypes, cleft lip(CL),CL and/or palate(CL/P) and cleft palate(CP). More than 350 genes have syndromic and/or nonsyndromic oral cleft associations in humans. Although genes related to genetic disorders associated with oral cleft phenotypes are known, a gap between detecting these associations and interpretation of their biological importance has remained. Here, using a gene ontology analysis approach, we grouped these candidate genes on the basis of different functional categories to gain insight into the genetic etiology of oral clefts. We identified different genetic profiles and found correlations between the functions of gene products and oral cleft phenotypes. Our results indicate inherent differences in the genetic etiologies that underlie oral cleft phenotypes and support epidemiological evidence that genes associated with CL/P are both developmentally and genetically different from CP only, incomplete CP, and submucous CP. The epidemiological differences among cleft phenotypes may reflect differences in the underlying genetic causes. Understanding the different causative etiologies of oral clefts is important as it may lead to improvements in diagnosis, counseling, and prevention.

Proton conducting ceramic cells(PCCs)are an attractive emerging technology operating in the intermediate temperature range of 500 to 700℃.In this work,we evaluate the production of hydrogen at intermediate temperatures by proton conducting ceramic cell electrolysis(PCCEL).We demonstrate a highperformance steam electrolysis owing to a composite positrode based on BaGd_(0.8)La_(0.2)Co_(2)O_(6-δ)(BGLC1082)and BaZr0.5Ce0.4Y0.1O3-δ(BZCY541).The high reliability of PCCEL is demonstrated for 1680 h at a current density as high as-0.8 A cm^(-2)close to the thermoneutral cell voltage at 600℃.The electrolysis cell showed a specific energy consumption ranging from 54 to 66 kW h kg^(-1)that is comparable to state-of-the-art low temperature electrolysis technologies,while showing hydrogen production rates systematically higher than commercial solid oxide ceramic cells(SOCs).Compared to SOCs,the results verified the higher performances of PCCs at the relevant operating temperatures,due to the lower activation energy for proton transfer comparing with oxygen ion ***,because of the p-type electronic conduction in protonic ceramics,the energy conversion rate of PCCs is relatively lower in steam *** faradaic efficiency of the PCC in electrolysis mode can be increased at lower operating temperatures and in endothermic conditions,making PCCEL a technology of choice to valorize high temperature waste heat from industrial processes into *** increase the faradaic efficiency by optimizing the materials,the cell design,or the operating strategy is a key challenge to address for future developments of PCCEL in order to achieve even more superior techno-economic merits.
