It also recommends future approaches to these issues in Japan. In contrast to the occupational environment, the indoor air in the residential environment contains multiple lowconcentration chemicals. Hence, the fundamental concept of approaches to preserving good indoor air quality consists of non-regulatory strategies based on indoor air quality information, for instance guideline values, labeling systems, and guidance. In addition, indoor air pollutants that are associated with serious public health effects and are extensively used in the residential environment have been the subject of regulations to restrict emission rates or ban the use of emission sources. Over the past forty years, many effective measures have been taken to improve indoor air pollution. However, as a result of major changes in building materials, consumer products, and lifestyle, new issues have arisen such as phthalates in indoor dust and indoor secondary emissions. Continuous and integrated risk assessment to identify high-risk factors is needed, as well as a comprehensive framework to provide further transparent information on emission sources, product ingredients, and management of indoor environments.","PeriodicalId":17443,"journal":{"name":"Journal of Urban Living and Health Association","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87236429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Of the many foods that elicit adverse reactions, soybean and soybean products, at the same time as representing an important protein source, are known as one of the major allergenic foodstuffs for the Japanese. However, no effective cure for allergic patients has been established. The strict elimination of the offending foods from the diet is therefore generally adopted as a prophylactic method in the treatment of food allergies, but may, if nutritional-fundamental foods are withdrawn for extended periods, lead to malnutrition in young patients. Accordingly, there is an urgent demand for food scientists to identify the proteins responsible for the allergic manifestation following ingestion of the foodstuff and to reduce allergenicity to enable the healthy use of soybean products. The present paper reviews recent information on the major allergens in soybean and the development of hypoallergenic soybean products. Further information on soybean allergens, sensitization to soybean allergens, persistence and symptoms of soybean allergy, and diagnostic features are available in a database at the Internet Symposium on Food Allergens: http://www.food-allergens.de.","PeriodicalId":17443,"journal":{"name":"Journal of Urban Living and Health Association","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74532347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The inhibitory effects of Equisetum arvense L. extract (Equisetum extract) on the metabolic activities of drugs with specific activity on cytochrome P-450 isozymes (1A2, 2C9, 2C19, 2D6, 2E1, and 3A4) were investigated using human liver microsomes. Equisetum extract (final concentration: 0, 0.1, 1, 10, and 100 μg/mL) and the respective representative substrates for CYP1A2, 2C9, 2C19, 2D6, 2E1, and 3A4 were incubated with human liver microsomes in order to examine the inhibitory effect. In the presence of Equisetum extract at 0.1 to 10 μg/mL, the residual activity of all the CYP isozymes examined was 68.2 to 105.3% of control, indicating no inhibition. Although CYP2D6 and CYP2E retained 66.7% and 73.4% of activity at Equisetum extract concentration of 100 μg/mL, the highest concentration examined in the tests, the residual activities of CYP1A2, 2C9, 2C19, and 3A4 were 21.4, 10.6, 8.9, and 8.6% respectively, showing IC50 values of 31.1, 22.3, 18.8, and 23.5 μg/mL, respectively. Certain components of Equisetum extract, such as flavons, appear to have inhibitory effect; but the amount of Equisetum extract required to exert the inhibitory effect on CYP isozymes is the same. Assuming that all components of the added Equisetum extract have inhibitory activity and that the mean molecular weight of such inhibitory components is 500, the IC50 values were converted into Ki values using Cheng-Prusoff’s equation; giving Ki values of the order of 10 μM. According to Rowland’s equation for estimating the rate of increase in AUC caused by drug-drug interactions, this suggests that there is no increase in AUC caused by the inhibitory effect of Equisetum arvense extract on CYP isozymes. This is a convenient method of estimating the degree of metabolic interaction between food and drugs.","PeriodicalId":17443,"journal":{"name":"Journal of Urban Living and Health Association","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84499504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An examination of the annual change in dust concentration showed a sudden decrease in the 1980s and 1990s and a gentler decrease in the 2000s. Concentrations of chloride and nitrate have remained at the same level while concentrations of sulfate and ammonium ion have shown a slight increasing trend in the last ten years. Regarding the correlation between dust and water-soluble ion concentrations, a strong correlation was observed between dust concentration and nitrate concentration. Regarding the correlation between dust and water-soluble ion concentrations and meteorological factors, a strong correlation of the temperature differences between Ikoma and Osaka to dust concentration and nitrate and ammonium ion concentrations was observed. Continental sand particle data showed a correlation of low relative humidity to high concentration of chloride, nitrate, and sulfate, and to low concentration of ammonium ions, while typhoon data showed a correlation of high wind velocity to high chloride concentration.","PeriodicalId":17443,"journal":{"name":"Journal of Urban Living and Health Association","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73451975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
