Many food products are claimed to be effective in controlling halitosis. Halitosis is caused mainly by volatile sulfur compounds (VSCs) such as H2S and CH3SH produced in the oral cavity. Oral microorganisms degrade proteinaceous substrates to cysteine and methionine, which are then converted to VSCs. Most treatments for halitosis focus on controlling the number of microorganisms in the oral cavity. Since tea polyphenols have been shown to have antimicrobial and deodorant effects, we have investigated whether green tea powder reduces VSCs in mouth air, and compared its effectiveness with that of other foods which are claimed to control halitosis. Immediately after administrating the products, green tea showed the largest reduction in concentration of both H2S and CH3SH gases, especially CH3SH which also demonstrated a better correlation with odor strength than H2S; however, no reduction was observed at 1, 2 and 3 h after administration. Chewing gum, mints and parsley-seed oil product did not reduce the concentration of VSCs in mouth air at any time. Toothpaste, mints and green tea strongly inhibited VSCs production in a saliva-putrefaction system, but chewing gum and parsley-seed oil product could not inhibit saliva putrefaction. Toothpaste and green tea also demonstrated strong deodorant activities in vitro, but no significant deodorant activity of mints, chewing gum or parsley-seed oil product were observed. We concluded that green tea was very effective in reducing oral malodor temporarily because of its disinfectant and deodorant activities, whereas other foods were not effective.

An age-associated androgen decrease and its pathological conditions are defined as late-onset hypogonadism (LOH). Among the various symptoms associated with LOH, a visceral fat increase is strongly associated with relatively low levels of testosterone. However, few studies have investigated the relationship between the Aging Males’ Symptoms (AMS) scores and metabolic abnormalities. Thus, we aimed to clarify this relationship by investigating the relationship between AMS scores and various markers in blood. During routine health examinations in 241 middle-aged males (52.7±7.5 years of age, mean±SD), 150 males (62.2%) displayed higher AMS values than normal. No statistical association was observed between total AMS scores and any testosterone value. All mental, physical and sexual AMS subscales were significantly positively correlated with insulin levels and HOMA-IR. Only sexual subscale scores were significantly inversely associated with free or bioavailable testosterone level. Males with insulin resistance (HOMA-IR≥2.5) demonstrated significantly higher AMS scores than those with normal insulin sensitivity (HOMA-IR<2.5). AMS values were positively correlated with fasting blood glucose, insulin and HOMA-IR values. Interestingly, univariate and multivariate analyses revealed that HOMA-IR≥2.5 was a significant predictor for detection of moderately severe AMS values (AMS≥37), whereas AMS≥37 was not a predictor of metabolic syndrome by International Diabetes Federation (IDF) criterion. In conclusion, almost 60% of healthy male subjects displayed abnormal AMS scores. AMS values were not associated with testosterone values but rather were related to insulin resistance, particularly in subjects with moderately severe AMS values. Insulin resistance-related general unwellness might be reflected by AMS values.

This study aims to examine which aspects of Japanese culture Chinese individuals adopted during their stay overseas and if they retained these cultural qualities after their return. Semi-structured interviews were conducted with five Chinese individuals who had stayed in Japan for one to eight years. Each interview lasted between 30 to 90 minutes and took place at X University in China, where returnees from Japan worked as academic staff. The results showed that the individuals acquired aspects of the Japanese culture in three main categories: rules or manners (observation of public rules), ways of communication (respecting other people's intentions), and philosophy of life (orientation toward co-existence with others). It appears that Chinese individuals firmly accepted and later internalized Japanese characteristics that they believed were admirable; therefore, it is believed that returnees retained these qualities even after returning to their original society.

This study examines two viewpoints on acculturation among the ethnic group of Zainichi Koreans, who settled, or whose ancestors settled, in Japan during the Japanese colonial era (1910-1945): the "traditional" view of acculturation (which includes four types of acculturation: assimilation, integration, marginalization, and separation), based on Western academic research, and the "context-specific" or "unattached" view, which conveys a desire for freedom from and a lifestyle or orientation that resists being constrained by pre-determined Korean or Japanese cultures and identities, preferring to identify as "human beings" or "individuals." Through an ANOVA test, our research found that unattachment score was highest in a more integrated group—contrary to our hypothesis that it would be highest in a more marginalized group, who irrespective of the conceptual connection between marginalization and unattachment have a tendency toward integration in their "real lives." These findings can help us understand the daily lives, identities, and perspectives of Zainichi Koreans and other ethnic minorities in Japan.
