Itabashi-ku, Japan

Daito Bunka University is a medium-sized four-year university with two campuses: one at Itabashi in Tokyo, and the other at Higashi Matsuyama in Saitama, Japan. The sports program is strong in rugby and marathon running, with the Ekiden team coming 4th in the prestigious January 2009 New Year Hakone Ekiden. Daito Bunka focuses primarily on cultural arts and humanities and is also known as one of the top calligraphy schools in the nation, and one of the few universities in Japan to teach Arabic and Urdu.

Background: Failure and delay in initial treatment contact for mental disorders has been recognized as an important public health problem. According to the concept of mental health literacy, recognition of symptoms is crucial to making decisions to seek or not seek professional help. The aims of this study were to investigate the types of health problems for which Japanese adults intend to seek help, their preferred sources of help, and the factors associated with help-seeking intentions. Methods: A cross-sectional web-based survey was conducted in June 2014 among Japanese adults aged 20-59 years. A total of 3308 eligible respondents were included in this study. Help-seeking intentions were measured by listing potential sources of help (including 'would not receive help') and asking which ones would be chosen in four health conditions indicated by irritability, dizziness, insomnia, and depressed mood, respectively. Results: In the case of dizziness, 85.9 % of the participants reported a positive help-seeking intention and 42.7 % gave first priority to seeking help from formal sources. These percentages were smaller in the cases of insomnia (75.4 and 25.0 %), depressed mood (74.9 and 18.7 %), and irritability (72.9 and 0.9 %). Multiple logistic regression analysis revealed that the factors significantly associated with help-seeking intentions were almost identical across the four health problems. In particular, perception of family and friends regarding help-seeking, psychiatric history, contact with people with mental illness, better health literacy, and neighborhood communicativeness were significantly associated with the overall help-seeking intention and also the help-seeking intention from formal sources for all the problems of dizziness, insomnia, and depressed mood. Conclusions: The majority of participants indicated their intentions to seek help, but psychological problems (insomnia and depressed mood) were less likely to induce help-seeking intentions than a physical problem (dizziness). Besides developing health literacy skills, community-based interventions for creating a friendly approachable atmosphere and facilitating daily interactions with family, friends, and neighbors may be worth considering as a possible public health strategy for encouraging help-seeking whether for psychological or physical problems. © 2016 Suka et al.

Given that visual estimation of an object's size is affected by an illusory figure, the present study investigates the Ebbinghaus size-illusion effect on visuomotor performance within different preview durations for viewing an object (no preview, 300, 700, 1500, and 3000 ms) before initiating the movement. Twenty participants performed the following actions: (a) grasping the object and (b) matching the perceived object size with the finger aperture configuration as in the grasping task. The illusion affected the grasping aperture size only in the no- and 300-ms preview durations, while the matching aperture was affected across all preview conditions. These results suggest that the preview duration influences the size illusion to affect the grasping performance, and subjects adopt different visuomotor processes, depending on preview duration.

To describe temporal change in tafone development, an S-shaped curve equation is proposed: Z=Zc [1-(n+1) exp (- β t)+n exp (- (1+1/n) β t)], where Z is observed tafone depth, Zc is ultimate tafone depth, t is time, and n and β are constants. The applicability of this model is examined using tafone data selected from seven sites, which are categorized into three different salt-weathering environments: a spray/splash-dominant (occasionally wave-affected) supra-tidal zone, aerosol-affected coastal regions, and inland desert areas. The results indicate that the equation can well describe tafone development in each of these environments. An investigation based on the values of n and β, determined through a best fit of the equation to the data, suggests that n characterizes site-specific environmental conditions and β reflects the magnitude of factors controlling the recession mechanism of tafone surfaces. It is found that (1) the maximum rate of tafone growth dramatically decreases from supra-tidal, through coastal, to desert environments, and (2) the growing mode of tafoni is different depending on the environmental settings. The erosional force to facilitate the development of tafoni at supra-tidal sites is estimated to be about 400 times greater than that in the general coastal area. © 2011 John Wiley & Sons, Ltd.

Mechanisms of Ageing and Development | Year: 2012

The lifespans of many poikilothermic animals, including the nematode Caenorhabditis elegans, depend significantly on environmental temperature. Using long-living, thermosensory mutants of C. elegans, we tested whether the temperature dependency of the mean lifespan is compatible with the Arrhenius equation, which typically represents one of the chemical reaction rate theories. The temperature dependency of C. elegans was the Arrhenius type or normal, but daf-2(e1370) mutants were quite different from the others. However, taking into account the effect of the thermal denaturation of DAF-2 with the temperature, we showed that our analyzed results are compatible with previous ones. We investigated the timing mechanism of one parameter (the onset of biodemographic aging (t0)) in the lifespan equation by applying the RNAi feeding method to daf-2 mutants in order to suppress daf-16 activity at different times during the life cycle. In summary, we further deepened the biological role of two elements, t0 and z (the inverse of the aging rate), in the lifespan equation and mean lifespan formulated by our diffusion model z2=4Dt0, where z is composed of t0 and D (the diffusion constant). © 2012 Elsevier Ireland Ltd.

Dysregulation of iron metabolism has been observed in patients with neurodegenerative diseases (NDs). Utilization of several importers and exporters for iron transport in brain cells helps maintain iron homeostasis. Dysregulation of iron homeostasis leads to the production of neurotoxic substances and reactive oxygen species, resulting in iron-induced oxidative stress. In Alzheimer's disease (AD) and Parkinson's disease (PD), circumstantial evidence has shown that dysregulation of brain iron homeostasis leads to abnormal iron accumulation. Several genetic studies have revealed mutations in genes associated with increased iron uptake, increased oxidative stress, and an altered inflammatory response in amyotrophic lateral sclerosis (ALS). Here, we review the recent findings on brain iron metabolism in common NDs, such as AD, PD, and ALS. We also summarize the conventional and novel types of iron chelators, which can successfully decrease excess iron accumulation in brain lesions. For example, iron-chelating drugs have neuroprotective effects, preventing neural apoptosis, and activate cellular protective pathways against oxidative stress. Glial cells also protect neurons by secreting antioxidants and antiapoptotic substances. These new findings of experimental and clinical studies may provide a scientific foundation for advances in drug development for NDs. Copyright © 2011 Satoru Oshiro et al. Source
