The state of the increase in the nonconformity rates of air environment in specific buildings was investigated using local government survey reports. The factors in the increase of carbon dioxide concentration were analyzed in consideration of the increase of ambient concentration, the characteristics of indoor concentrations and the characteristics of the government reports. The results were as follows. 1 The nonconformity rates of humidity, temperature and carbon dioxide concentration have increased with the number of specific buildings since 1999. And reports made by the owners of specific buildings are substituted for inspections by government officials in most prefectures. 2 One of the factors in the increase of nonconformity rates of temperature, humidity and carbon dioxide concentration is the increase of reports using measurement data by building maintenance suppliers. The nonconformity rates of humidity and carbon dioxide concentration were higher in northern prefectures. 3 The frequency of indoor carbon dioxide concentration in specific buildings in Tokyo was similar to that in Osaka. The frequency distribution of the differences between indoor concentration and outdoor concentration in Tokyo follows Weibull frequency distribution. 4 The ambient concentration of carbon dioxide has increased especially in urban areas. The increase of ambient concentration is thought to increase the indoor concentrations in specific buildings. 5 The nonconformity rates of carbon dioxide concentration depend on not only ambient concentration but also the rates of ventilation reduction and survey methods by governments. The nonconformity rates were calculated using an equation composed on the basis of Weibull frequency. The coefficients of these factors were calculated using the equation and the survey data on all Japan. 6 The increase of ambient concentration made the nonconformity rate of indoor concentration 3.1% higher and ventilation reduction made it 7.2% higher and the change of survey method made it 11.6% higher in these nineteen years. These results showed that the increase of nonconformity rates depends on several factors. Therefore it is necessary to design integrated countermeasures in order to decrease these nonconformity rates.

Cooling equipments have been remarkably introduced to school classrooms recently, and the saturation level of air conditioners in public schools is reached almost 100% in Tokyo City Area. Before cooling equipments were installed to classrooms, an appropriate amount of ventilation might have been maintained because windows of classrooms were mostly open during summer period. On the other hand, the ventilation rates were often reduced during winter period because of less frequency of window opening. Such less ventilation and worse air quality could be caused during summer period as well in accordance with the introduction of cooling equipments. Indoor air environment audit in schools has been conducted regularly by local government in Japan. The audit is conducted every two months in large scale schools which total floor area was over 8000 m2, and conducted generally once or twice a year in all schools irrespective of school size. Although the results of this audit could be useful to realize the indoor air quality in schools during various seasons, the results of the measurements are little made public from the local government. Therefore the results of the audit were used as the evidence in previous study. In the Law for Maintenance of Sanitary Environment in Buildings, it is demanded the CO2 concentration in the room to be 1000 ppm or less. In the previous study, it was reported that the mean CO2 concentration in the target elementary school classrooms was blow 1000 ppm during summer and midterm period. Furthermore the mean CO2 concentration in the secondary school classrooms was above 1000 ppm during all periods in the previous study. Recently indoor air quality monitoring in public building has been conducted worldwide. The French Indoor Air Quality Observatory (OQAI) was commissioned to assess children's exposure to various indoor air pollutants in schools. In the French study, the ICONE (Indice de CONfinement d'air dans les Ecoles) index was used to evaluate air stuffiness during occupied periods. One of the purposes of this study is to use the ICONE index to the results of air environmental audit for school classrooms in Tokyo district X. The analyzed schools in this study are elementary and secondary public schools located in Tokyo metropolitan district X. The period of analysis was set as 6 years from 2007 to 2012 fiscal year. The following conclusions were obtained; 1) In 63 % of elementary schools and 20 % of secondary schools, the ICONE index during summer period showed the lowest value, i.e., the lowest air stuffiness, and that during winter period showed the highest. 2) During summer period the percentage of schools with a ICONE score of 3, 4 or 5 in secondary schools was significantly larger than that in elementary schools. During winter period the difference in the above percentage between elementary and secondary schools was contrastively small. 3) The tendency that the windows are apt to close by introducing cooling equipments might be more detected in secondary schools than elementary schools. 4) The relationship between the number of occupants and the suspended particles concentration was not clear. The evidence that students or their activity are primary source of particulate matter was not obtained. 5) The worldwide data comparison for IAQ in schools could be useful, and the results of the audit should be utilized as feedback information to improve the indoor air quality.

Objective The cardiac function, blood distribution, and oxygen extraction in the muscles as well as the pulmonary function determine the oxygen uptake (VO2) kinetics at the onset of exercise. This factor is called the VO2 time constant, and its prolongation is associated with an unfavorable prognosis for heart failure (HF). The mitochondrial function of skeletal muscle is known to reflect exercise tolerance. Morphological changes and dysfunction in cardiac mitochondria are closely related to HF severity and its prognosis. Although mitochondria play an important role in generating energy in cardiomyocytes, the relationship between cardiac mitochondria and the VO2 time constant has not been elucidated. Methods We calculated the ratio of abnormal cardiac mitochondria in human myocardial biopsy samples using an electron microscope and measured the VO2 time constant during cardiopulmonary exercise testing. The VO2 time constant was normalized by the fat-free mass index (FFMI). Patients Fifteen patients with non-ischemic cardiomyopathy (NICM) were included. Patients were divided into two groups according to their median VO2 time constant/FFMI value. Results Patients with a low VO2 time constant/FFMI value had a lower abnormal mitochondria ratio than those with a high VO2 time constant/FFMI value. A multiple linear regression analysis revealed that the ratio of abnormal cardiac mitochondria was independently associated with a high VO2 time constant/FFMI. Conclusions An increased abnormal cardiac mitochondria ratio might be associated with a high VO2 time constant/FFMI value in patients with NICM.

Vitamins are a family of micronutrients comprising 13 groups of organic compounds, of which vitamin B1 was identified first, approximately 110 y ago. Deficiency of each vitamin results in specific symptoms, such as neuropathy, dermatitis, diarrhea, dementia, pernicious anemia, scurvy, blindness, rickets, and bleeding. Almost all vitamins can modulate the functions of enzymes and/or other proteins involved in the formation of bone and soft tissues, generation of energy, and regulation of homeostasis via specific vitamin–protein interactions. In addition to the well-known physiological roles of vitamins, novel modes of action of vitamins have been elucidated. These new functions could contribute to extending healthy life expectancy by preventing and curing lifestyle-related diseases. In this mini-review, we introduce the functional properties of three vitamins, vitamin B3 (niacin), biotin, and vitamin K, for the prevention of age-related diseases.

To examine the clinical significance of the insulin resistance index as determined by homeostasis model assessment (HOMA-IR), we investigated the relationship between HOMA-IR and the insulin resistance estimated by the euglycemic-hyperinsulinemic clamp method in various subgroups and compared the significance of HOMA-IR with that of fasting plasma insulin levels (FIRI). HOMA-IR was significantly correlated to the inverse of the glucose infusion rate (1/GIR) in both diabetic and non-diabetic subjects (r=0.747, P<0.0001 and r=0.419, P<0.002, respectively). In the diabetic patients, treatment with sulfonylureas did not weaken this correlation (r=0.833, P<0.0001). HOMA-IR was found to be closely related to FIRI (r=0.932, P<0.0001), but HOMA-IR was more closely associated with 1/GIR than FIRI was. HOMA-IR as well as 1/GIR was correlated with the visceral fat area (VFA) more closely than with the subcutaneous fat area (SFA), while FIRI was correlated almost equally with both of them. In conclusion, HOMA-IR is a convenient and beneficial method for evaluating insulin resistance, especially in subjects with visceral fat accumulation, and reflects insulin resistance obtained by euglycemic clamp more accurately than FIRI alone.
