[Purpose] Motion capture system is difficult to use in daily life. The aim of this study was to propose an estimation model for knee and ankle joint angle measurements and locate body center of gravity (COG) of the extension phase during standing-up motion. [Subjects and Methods] Seven healthy male volunteers were enrolled. An estimation model was proposed for the knee and ankle joint angle measurements by combining the angle and acceleration of the trunk, based on readings from the inertial sensor attachment on the subject’s chest, during the extension phase. Joint angles and COG position were compared to those obtained by a motion capture system. [Results] The joint angles and COG position demonstrated high correlation coefficients which represent strong correlation between the proposed model and the motion capture system. The proposed model could estimate the joint angle during extension phase, with a maximum error of 4.58 degrees, as well as COG position in the horizontal and vertical directions with maximum errors of 4.48 cm and 3.19 cm, respectively. [Conclusion] The proposed system could be used instead of motion capture system to estimate knee and ankle joint angles; however, the estimation of the COG position was insufficient because of lacked accuracy. © 2017 The Society of Physical Therapy Science.

The mechanisms regulating the maintenance of quiescent adult stem cells in teeth remain to be fully elucidated. Our aim is to clarify the relationship between BrdU label-retaining cells (LRCs) and sonic hedgehog (Shh) signaling in murine teeth. After prenatal BrdU labeling, mouse pups were analyzed during postnatal day 1 (P1) to week 5 (P5W). Paraffin sections were processed for immunohistochemistry for BrdU, Sox2, Gli1, Shh, Patched1 (Ptch1) and Ki67 and for in situ hybridization for Shh and Ptch1. Dense LRCs, Gli1-(+) cells and Ptch1-(+) cells were co-localized in the outer enamel epithelium of the apical bud and apical dental papilla of incisors. In developing molars, dense LRCs were numerous at P1 but then decreased in number over the course of odontogenesis and were maintained in the center of pulp tissue. Gli1-(+) cells were maintained in the pulp horn during the examined stages, while they increased in number and were maintained in the center of pulp tissue during P2-5W. Ptch1-(+) cells were localized in the pulp horn at P1 and increased in number in the center of the pulp after P3W. Shh mRNA was first expressed in the enamel epithelium and then shifted to odontoblasts and other pulp cells. Shh protein was distributed in the epithelial and mesenchymal tissues of incisors and molars. These findings suggest that quiescent dental stem cells are regulated by Shh signaling, and that Shh signaling plays a crucial role in the differentiation and integrity of odontoblasts during epithelial-mesenchymal interactions and dentinogenesis. © 2017 Springer-Verlag Berlin Heidelberg

To simultaneously examine the impact of childhood abuse history on borderline personality traits, negative life events, and depression, undergraduate students (N=243) were studied by questionnaire surveys with one week intervals. Neglect and emotional abuse as well as sexual maltreatment predicted borderline personality traits and baseline depression. Baseline depression as well as the impact of negative life events occurring the week prior predicted depression a week later. However, after considering the baseline depression level, child abuse history failed to predict the follow-up depression level. Borderline personality traits did not moderate these findings. Childhood emotional and sexual abuse history may influence depression and borderline personality traits. © 2010.

[Purpose] The purpose of this research was to examine the effect of PWB gait exercise which involves conscious heel contact on the hip abductor muscle of patients with hip diseases. [Subjects] The subjects were 10 patients who underwent surgery as well as 10 healthy females as the control group. [Methods] The grade of muscle activity of the gluteus medius in gait exercise without conscious heel contact, and with conscious heel contact werecompared using integrated EMG analysis and wavelet frequency analysis. [Results] The degree of muscle activity in the gluteus medius of patients were significantly increased by gait exercise with conscious heel contact. [Conclusion] Gait exercise with conscious heel contact could become an effective method for quantitative and qualitative training of the hip abductor muscle. © 2012, The Society of Physical Therapy Science.

Objectives In the Transactional Model of Stress and Coping, coping strategies and presence of social support influence health behavior. This study aimed to reveal relationships between mothers' coping styles, self-health behavior, children's oral health care, and social support from dental professionals. Methods A total of 313 mothers participated in this study from all elementary schools in 2 cities in Japan. We classified participants into high and low groups with reference to self-health behavior and oral health care. To examine the associations of mother's coping styles, health behavior, and the presence of social support, logistic regression analysis was conducted. Results There were significant differences in mother's coping styles associated with self-health behavior, oral health care, and presence of social support. In logistic regression analysis, the good self-health behavior group was more likely to use coping strategies of obtaining information and positive interpretation, to have fewer children, and less frequent use of avoidance-like thinking. The good oral health care group had a higher probability of obtaining information and using problem focused coping, and a lower probability of evading one's responsibility. Those who consulted dental offices used more positive interpretation, while mothers who did not consult dental offices used evading one's responsibility more frequently. Conclusions Mother's coping styles had different associations with self-health behavior and children's oral health care. We may be able to use behavioral modification strategies effectively according to whether a mother consults with dental professionals. Future intervention studies based on this research are expected. © 2017

Text messaging may be excessive and young people may be dependent on it. We distributed the Self-perception of Text-message Dependency Scale (STDS), Hospital Anxiety and Depression Scale (HADS), Temperament and Character Inventory (TCI), and Relationship Questionnaire (RQ) to 223 Japanese university students in a two-wave study, separated by a 5-month interval. The STDS yielded a three-factor structure. The STDS scores across the two measurement occasions were stable across time (except for the Relationship Maintenance subscale). A hierarchical cluster analysis suggested a three-class structure interpreted as Normal Users, Excessive Users, and Dependent Users. Excessive Users and Dependent Users were characterized by a young age at initial mobile phone use, more frequent use of text messaging, higher Novelty Seeking, and better Other-Model patterns of adult attachment. Unlike Excessive Users, Dependent Users were characterized by lower Self-directedness, poorer Self-Model of adult attachment, and higher anxiety and depression. The Excessive Users, but not the Dependent Users, were characterized by high Reward Dependence and Co-operativeness. The present study demonstrated that the STDS has a robust factor structure, good construct validity, and temporal stability (except for Relationship Maintenance subscale); students could be classified into normal, excessive, and Dependent Users of the text messaging; and Dependent Users were characterized by Excessive Use and personality immaturity. © 2013 Elsevier Ireland Ltd.

This study focused on the functional aspects of narcissism in regulating self-conscious emotions (guilt, shame, hubristic pride, and achievement-oriented pride) as well as two other attribution styles (externalization and detachment). The authors investigated Japanese university students (N = 452) with regard to their self-conscious emotions using the Test of Self-Conscious Affect-3 (TOSCA-3) and their narcissistic personality using the short version of Narcissistic Personality Inventory (NPI-S). Structural equation modeling was used for the analysis. The authors found that narcissism led individuals to feel achievement-oriented pride, hubristic pride, externalization, and detachment, but inhibited feelings of shame. It did not have a significant effect on guilt. Shame-proneness prompted hubristic pride and externalization. Guilt-proneness inclined an individual toward achievement-oriented pride, but deterred externalization. In this article, the authors present and interpret these results in detail and then discuss how they can be utilized in psychotherapy. © 2012 The Menninger Foundation.

Objectives This descriptive study of 314 students was conducted to determine whether there were any relationships of their demographic variables with a health-promoting lifestyle profile. Methods The Japanese version of the Health Promoting Lifestyle Profile II (HPLP-II) questionnaire was used to investigate students' lifestyles. One-way analysis of variance (ANOVA) and multiple comparison procedures using the Scheffe test were conducted to identify significant differences among university year (first, second, etc.) groups. The t-test independent participants was utilized to compare the HPLP-II scores according to gender and living with family (yes/no). Multiple regression analysis was used to analyze the effects of various demographics on the overall HPLP-II score and the six health-promoting lifestyle subscales. Results The whole cohort of participants had an overall HPLP-II mean score of 2.50 (SD = 0.29), with the highest mean score being for interpersonal relations (3.05 ± 0.44), and the lowest mean score being for health responsibility (2.01 ± 0.53). The overall HPLP-II score of the students during the first university year was 2.59 (SD = 0.29), and this score progressively declined in their second year (2.49 ± 0.29), third year (2.47 ± 0.28), and fourth year (2.45 ± 0.30). Female students practiced significantly better health responsibility, interpersonal relations, and nutrition than males, and male students practiced significantly better physical activity than females. The students who were living with family had significantly higher nutrition scores than those not living with family. Conclusions These significant findings linking the HPLPII, university year level, and living with family (yes/no) in university students will enable healthcare providers to develop interventions to assist students in improving their health lifestyles in the university environment and will help in devising suitable education programs. © The Japanese Society for Hygiene 2011.

Electron-transferring flavoprotein (ETF) from the anaerobic bacterium Megasphaera elsdenii is a heterodimer containing two FAD cofactors. Isolated ETF contains only one FAD molecule, FAD-1, because the other, FAD-2, is lost during purification. FAD-2 is recovered by adding FAD to the isolated ETF. The two FAD molecules in holoETF were characterized using NADH. Spectrophotometric titration of isolated ETF with NADH showed a two-electron reduction of FAD-1 according to a monophasic profile indicating that FAD-1 receives electrons from NADH without involvement of FAD-2. When holoETF was titrated with NADH, FAD-2 was reduced to an anionic semiquinone and then was fully reduced before the reduction of FAD-1. The midpoint potential values at pH 7 were +81, -136 and -279 mV for the reduction of oxidized FAD-2 to semiquinone, semiquinone to the fully reduced FAD-2 and the two-electron reduction of FAD-1, respectively. Both FAD-1 and FAD-2 in holoETF were reduced by excess NADH very rapidly. The reduction of FAD-2 was slowed by replacement of FAD-1 with 8-cyano-FAD indicating that FAD-2 receives electrons from FAD-1 but not from NADH directly. The present results suggest that FAD-2 is the counterpart of the FAD in human ETF, which contains one FAD and one AMP. © The Authors 2013.
