The authors first identified factors associated with a high degree of formality and factors associated with a low degree of formality, for various clothing designs, patterns, and colors. By combining these factors, the authors then created 32 sample design images and conducted a sensory test of these images utilizing the semantic differential method. The test results demonstrated that degree of body coverage and clothing color strongly impacted on perceptions of "formality". Next, a trial has been made to correlate the ratings of the created design images with ratings of actual clothing designs. The authors created three formal wear designs, in which a model dressed. Images of each design were converted into four plain color schemes - red, yellow, black, and white - using the 4D-box application. In addition, the authors created a total of 30 sample images with dotted and floral patterns of these colors and repeated the same sensory test. The results indicated that design had the strongest influence on the perception of "formality". However, factor analysis results were similar, revealing that "formality", "warmth", and "potency" were the three factors most strongly correlated with a positive perception.

The state in which physical and mental functions are deteriorated with aging is called frailty, and decrease in muscle mass and muscle strength with aging accompanying deterioration of physical function is called sarcopenia. Frailty and sarcopenia are found in older adults, which is a major obstacle to achieve healthy longevity. Estimation of prevalence and number of patients, as well as elucidation of risk factors in frailty and sarcopenia are important for the prevention of frailty and sarcopenia. The prevalence of frailty determined by criteria based on the method of Fried et al. was 5.2% for men and 20.9% for women in a cohort of randomly selected community-living population, and the estimated number of people with frailty was about 0.77 million men and 2,22 million women among the population aged 65 years and over in Japan. The prevalence of sarcopenia by the Asian Working Group for Sarcopenia (AWGS) criteria was 9.6% for men and 7.7% for women. The number of people aged 65 years and over with sarcopenia in Japan was estimated to be 1.64 million for men and 1.39 million for women. The onset of frailty was related to physique, physical function, cognitive function, depression, and various chronic diseases. Depression and lack of exercise were significant risk factors of sarcopenia. Physical activity, nutrition and control of chronic diseases are required for the prevention of frailty and sarcopenia, and the prevention will be an important issue for health and longevity in Japan.

BACKGROUND: We appraised time trends of Japanese life expectancy (LE) and healthy life expectancy (HALE) by gender, LE-HALE and (LE-HALE)/LE figures, along with the women-men's differences.METHODS: Using the Japanese LE and HALE values from 1990 through 2013 by gender in the article by the GBD 2013 DALYs and HALE Collaborators, we examined trends of LE and HALE, and their 5- or 3-year changes. We also probed LE-HALE and (LE-HALE)/LE values, and the women-men's differences.RESULTS: LE consistently elongated as reported 76.0, 76.5, 77.6, 78.7, 79.3 and 80.1 years for men from 1990 to 2013; and 82.0, 82.8, 84.3, 85.5, 86.1 and 86.4 years for women, respectively. Both time trends demonstrated a significant linear increase (p for trend < 0.001). LE changes were 0.4, 1.1, 1.1, 0.7 and 0.7 years for men, and 0.9, 1.5, 1.2, 0.6 and 0.3 years for women. The trends were statistically significant (p < 0.001), except for 2010-2013 partly due to 3-year interval. HALE also steadily lengthened as seen 68.1, 68.4, 69.1, 69.9, 70.8 and 71.1 years for men from 1990 through 2013; and 72.2, 72.9, 74.0, 74.8, 75.4 and 75.6 years for women. Both time trends showed almost a linear increase (p < 0.05). HALE changes were 0.4, 0.6, 0.8, 0.9 and 0.3 years for men, and 0.7, 1.0, 0.8, 0.6 and 0.2 years for women, without statistical significant trends. LE-HALE values were 8.0, 8.0, 8.5, 8.8, 8.6 and 8.9 years for men; and 9.7, 9.9, 10.4, 10.7, 10.7 and 10.8 years for women. (LE-HALE)/LE figures were 10.5, 10.5, 10.9, 11.1, 10.8 and 11.2% for men, and 11.9, 12.0, 12.3, 12.5, 12.4 and 12.5% for women. LE women-men's differences were 5.9, 6.4, 6.8, 6.8, 6.8 and 6.3 years, and the HALE figures were 4.2, 4.5, 4.9, 4.9, 4.6 and 4.5 years.CONCLUSIONS: LE and HALE consistently linearly elongated for both sexes over the study period. Not only LE-HALE but also (LE-HALE)/LE values were still growing for both sexes. Public health measures, nursing-care/services as well as social security schemes are called for to further elevate longevities, HALE in particular, and enhance quality of life and well-being.

Aim: Little is known about longitudinal changes of body composition measured by dual-energy X-ray absorptiometry (DXA) in middle-aged and elderly individuals. We evaluated longitudinal changes of body composition, and age and sex differences in appendicular skeletal muscle mass. Methods: Participants were 1454 community-dwelling Japanese men and women aged 40-79 years. Body composition at baseline and 6-year follow up was measured by DXA. Results: Fat increased significantly in men of all ages, and in women aged in their 40s and 50s. Among men, arm lean tissue mass (LTM) changed by 0.9%, -0.5%, -1.4% and -3.7%, respectively, for the 40s to the 70s, and decreased significantly in the 60s and 70s. Leg LTM in men changed by -0.4%, -1.3%, -1.7% and -3.9%, respectively, and decreased significantly from the 50s to the 70s. Compared with the preceding age groups, significant differences were observed between the 60s and 70s in arm and leg LTM change in men. Among women, arm LTM changed by 0.7%, 0.2%, 1.6% and -1.5%, respectively, which was significant in the 60s and 70s. Leg LTM decreased significantly in all age groups of women by -2.0%, -2.8%, -2.4% and -3.9%, respectively. With respect to sex differences, leg LTM loss rates were significantly higher in women than men at the 40s and 50s. Conclusions: Longitudinal data suggest that arm and leg LTM decreased markedly in men in their 70s, and leg LTM had already decreased in women in their 40s. © 2013 Japan Geriatrics Society.

Aim: The present study aimed to evaluate age-related changes in skeletal muscle mass among community-dwelling middle-aged and elderly Japanese. Methods: This 12-year longitudinal study of a community-dwelling population in Japan included 15948 examinations of 1962 men and 1990 women. We assessed appendicular muscle mass (AMM) using dual X-ray absorptiometry and calculated the skeletal muscle index (SMI) using the AMM divided by height squared (kg/m2). Low muscle mass was defined as muscle mass minus two standard deviations below the mean for young healthy adults. Leg extension power (watts) was measured as an index of muscle function. Longitudinal data of skeletal muscle mass were analyzed using a general linear mixed-effect model. Results: The prevalence of low muscle mass at the first wave of examinations was 27.1% in men and 16.4% in women. Longitudinal analysis showed that skeletal muscle mass decreased with aging during the 12-year study period except in middle-aged men, and to a greater extent in elderly men (P for trend, <0.001). Skeletal muscle mass decreased slightly, but significantly, in women. Although a cross-sectional analysis showed that SMI did not differ with age in women, leg extension power per leg muscle mass and grip strength per arm muscle mass as indices of muscle quality were significantly lower in older women (P for trend, <0.001 for both). Conclusion: Age-related decreases in muscle mass were trivial, especially in women, but the quality of muscle decreased with aging in both sexes. © 2014 Japan Geriatrics Society.

Throughout my research life, I experienced to discover the causes of some neurological diseases in Japan. 1) SMON (subacute myelo-optico-neuropathy). Since the early 1960s, a peculiar neurological disease became prevalent throughout Japan. Through the chemical analysis of the green urine, characteristic of this disease, it was found that this disease was caused by intoxication of the administered clioquinol, an anti-diarrheal drug. This discovery is a big topic in the history of Japanese medicine. 2) In early 1970s, I experienced many young patients with oedema and polyneuropathy in Kagoshima. Finally it was found that the disease was the long-forgotten beriberi, which had disappeared several decades ago. We must always be aware of beriberi even now, as far as we eat well-polished rice. 3) In 1972, we noticed a group of sporadic paraparesis in Kagoshima, which was 20 years later confirmed to be induced by human T lymphotropic virus type-I (HTLV-I). We named this disease as "HTLV-I associated myelopathy" (HAM). It gave a strong impact that the causative virus of adult T cell leukemia (ATL) can induce entirely different diseases, in terms of both the clinical course and the pathological features. It was also proven that HAM was identical with tropical spastic paraparesis, (TSP), which had been prevalent in many areas of tropical zones. These experiences are good examples of our slogan "to keep in mind to send message of scientific progress from the local area to the international stage". © 2010 The Japan Academy.

As a purpose of the long term care insurance in Japan, which was inaugurated in 2000, the achievement of "self-support"of aged people was stressed, which means, the prevention of fragility and senility. This system incorporated the new prevention service of "yo-shien" since its beginning. After 5 years experience since 2000, this preventive service was not always found to be effective. Therefore a new procedure of rehabilitation was introduced in 2006, mainly to strengthen the impaired muscle strength to achieve self-support. This new service was evaluated after few years experience and found to be effective in preventing the aggravation of disability and in suppressing the total cost of insurance, compared with control group. To prevent the fragility and senility of aged people, this preventive procedure in the long term care insurance will be effective.

The aim of this study was to evaluate tissue distribution of vitamin E isoforms such as α-and γ-tocotrienol and c-tocopherol and interference with their tissue accumulation by α-tocopherol. Rats were fed a diet containing a tocotrienol mixture or γ-tocopherol with or without a-tocopherol, or were administered by gavage an emulsion containing tocotrienol mixture or c-tocopherol with or without a-tocopherol. There were high levels of a-tocotrienol in the adipose tissue and adrenal gland, γ-tocotrienol in the adipose tissue, and γtocopherol in the adrenal gland of rats fed tocotrienol mixture or γ-tocopherol for 7 weeks. Dietary α-tocopherol decreased the a-tocotrienol and γ-tocopherol but not γ-tocotrienol concentrations in tissues. In the oral administration study, both tocopherol and tocotrienol quickly accumulated in the adrenal gland; however, their accumulation in adipose tissue was slow. In contrast to the dietary intake, α-tocopherol, which has the highest affinity for a-tocopherol transfer protein (αTTP), inhibited uptake of γ-tocotrienol to tissues including adipose tissue after oral administration, suggesting that the affinities of tocopherol and tocotrienol for αTTP in the liver were the critical determinants of their uptake to peripheral tissues. Vitamin E deficiency for 4 weeks depleted tocopherol and tocotrienol stores in the liver but not in adipose tissue. These results indicate that dietary vitamin E slowly accumulates in adipose tissue but the levels are kept without degradation. The property of adipose tissue as vitamin E store causes adipose tissuespecific accumulation of dietary tocotrienol. © 2011 AOCS.
