    ABSTRACT: Objective: Cigarette smoking has been found to be more prevalent among adults and youths with a minority sexual orientation (lesbian, gay, bisexual, LGB) than among the general population, while less is known about smoking among LGB youth in low- and middle-income countries. The goal of the study was to examine cigarette smoking in relation to sexual orientation in a community-based sample of youth in Shanghai, China. Methods: A multi-center cross-sectional survey of 17,016 youth aged 15-24 years was conducted in rural and urban areas of Hanoi, Vietnam; Taipei, Taiwan; and Shanghai, China in 2006. In this article, analysis was restricted to the 6,299 respondents in Shanghai. Assessments included ever smoking, age at first smoking, frequency of smoking, and number of cigarettes smoked daily. Logistic regression was used to estimate the association between sexual orientation and cigarette smoking. Results: Nine percent (594/6,299) of eligible participants considered themselves as LGB youths; 34.2% ever smoked, 14.81% initiated smoking before age 13, 15.9% smoked in the past 30 days, and 14.1% were moderate or heavy smokers. LGB identity predicted moderate or heavy smoking (OR 2.2, 95% CI 1.3, 3.9). Male LGB youth smoked more cigarettes daily (OR 2.2, 95% CI 1.3, 3.9) whilst female LGB youth reported less any prior cigarette use (OR 0.7, 95% CI 0.5, 1.0). Conclusions: Few meaningful disparities in cigarette smoking were related to sexual orientation, except male LGB youth consumed more cigarettes daily. Prevention and cessation should target this population, especially male LGB youth.

    ABSTRACT: Objective: The aim of the present study is Vibrio cholerae non-O1 existing in river. Bacteria are known to inhabit all kinds of environment. Vibrionaceae is widely distributed in environmental water. Vibrio spp. have been identified as a cause of toxicity in fish and shellfish. One condition affecting the survival of pathogenic microorganisms in environmental water is the salt concentration, and they have been reported to inhabit brackish water. However, V. cholerae non-O1 has also been detected in fresh water, and its properties suggest that it can survive in river water. Methods: Sampling was performed 4 times at 4 points during a 5-month period from July to November at about 1-month intervals from the Sagami River in 1985. River water bacteria were identified, and V. cholera non-O1 isolated. I investigated the relationship between the bacterial flora in river water and the detection of V. cholerae non-O1. Results: There were significant differences in the composition of bacterial flora with and without the isolation of V. cholerae non-O1 (Chi-square test) (χ(2) = 24.70 > 22.0 (p = 0.005), df = 8). A correlation between changes in the composition of the river water bacterial flora and detection of V. cholerae non-O1 was identified. Conclusion: Therefore, V. cholerae non-O1 exists in the river.

    ABSTRACT: Objective: The aim of this study was to investigate the linkage among climate parameters, total ambulance transports and the number of deaths in Asahikawa City in northern Japan. Methods: Monthly data on total ambulance transports and the number of deaths from January 2004 to December 2011 were obtained from Asahikawa City Fire Department and the Asahikawa City official website. Climate parameters for the required period were also obtained from the Japan Meteorological Agency, Japan. To adjust for the population, we also used monthly population data on Asahikawa City. The linkage among climate parameters, total ambulance transports and the number of deaths was evaluated by ecological analysis. Results: The mean air temperature in the Asahikawa area was 7.3 ± 10.1 °C. Total ambulance transports (/a hundred thousand people/day) and the number of deaths (/a hundred thousand people/day) were 10.0 ± 0.6 and 2.6 ± 0.3, respectively. Using quadratic curves, total ambulance transports and the number of deaths were weakly correlated with some climate parameters. The number of deaths was weakly and positively correlated with total ambulance transports. Conclusion: A weak linkage among climate parameters, total ambulance transports and the number of deaths was noted in Asahikawa City, Japan. However, these associations were not as high as expected.

    ABSTRACT: The Hokkaido Study on Environment and Children’s Health is an ongoing cohort study that began in 2002. The study consists of two prospective birth cohorts, the Sapporo cohort (n = 514) and the Hokkaido large-scale cohort (n = 20,940). The primary goals of this study are to first examine the potential negative effects of perinatal environmental chemical exposures on birth outcomes, including congenital malformations and growth retardation; second, to evaluate the development of allergies, infectious diseases and neurodevelopmental disorders and perform longitudinal observations of the children’s physical development to clarify the causal relationship between these outcomes and environmental chemicals; third, to identify individuals genetically susceptible to environmental chemicals; finally, to identify the additive effects of various environmental factors in our daily life, such as secondhand smoke exposure or low folate intake during early pregnancy. In this paper, we introduce our recent progress in the Hokkaido study with a cohort profile updated in 2013. For the last ten years, we followed pregnant women and their offspring, measuring various environmental chemicals, i.e., PCB, OH-PCB and dioxins, PFCs (Perfluorinated Compounds), Organochlorine pesticides, Phthalates, bisphenol A and mercury. We discovered that the concentration of toxic equivalents (TEQ) of dioxin and other specific congeners of PCDF or PCDD have effects on birth weight, infants’ neurodevelopment and immune function. There were significant gender differences in these effects; our results suggest that male infants have more susceptibility to those chemical exposures than female infants. Interestingly, we found maternal genetic polymorphisms in AHR, CYP1A1 or GSTs that significantly modified the dioxin concentrations in maternal blood, suggesting different dioxin accumulations in the bodies of individuals with these genotypes, which would lead to different dioxin exposure levels. These genetic susceptibility factors influenced the body size of children born from mothers that either smoked or were passively exposed to tobacco smoke. Further studies investigating the correlation between epigenetics, the effects of intrauterine exposure to environmental chemicals and developmental factors related to health and disease are warranted.

    ABSTRACT: Objectives: To clarify whether smoking was associated with elevated intraocular pressure (IOP) and to evaluate the interrelationship among IOP, blood viscosity, and smoking. Methods: This cross-sectional study analyzed health examination data obtained between 2001 and 2004 from 1113 individuals (829 men and 284 women), ranging in age from 28 to 79 years, who had not undergone any ocular surgery or medical treatment for hypertension, ocular hypertension, and glaucoma. Results: Multiple-regression analysis showed that systolic blood pressure (SBP), diastolic blood pressure (DBP), body mass index (BMI), and number of cigarettes smoked per day had a significantly positive association with IOP in men (P < 0.05). In women also, SBP, DBP, and BMI were positively related to IOP (P < 0.05). On the contrary, age had a significant negative association with IOP in both sexes (P < 0.01). Analysis of covariance and multiple logistic regression analyses showed that the adjusted mean IOP and the multivariate odds ratios for IOP increased with increasing cigarette consumption in men (P for trend = 0.01 and 0.06, respectively). Analysis of covariance found that smoking was significantly associated with both high IOP and high hematocrit in men (P for trend <0.05); however, the adjusted mean IOP values were higher in smokers than in nonsmokers, regardless of the hematocrit level. Conclusions: The results of this study suggested that the IOP level may be substantially affected by smoking habit in middle-aged and older Japanese men.

    ABSTRACT: To evaluate the protective effects ofGinkgo biloba extract (GBe) which has antioxidant activity against peripheral neuropathy due to diabetes mellitus, slow axonal transport and morphology of sciatic nerve including endoneurial microvessels were examined in 12 rats with diabetes mellitus induced by streptozotocin (STZ, 60mg/kg, b.w., i.p.). Six of the diabetic rats were treated with 0.1 % of GBe for 6 weeks from one week after the STZ injection. Serum glucose and lipid peroxide levels in GBe-treated diabetic rats were significantly lower than those in untreated diabetic rats (p<0.01, respectively), though the serum glucose level was higher than that in the control rats. L-[35S] methionine pulse radiolabeling with subsequent gel fluorography demonstrated that mean velocities (Vmean) of actin and β-tubulin, i.e. slow component b (SCb) transport in untreated diabetic rats were significantly lower than those in control rats (p<0.05, respectively); mean diameter of axons in the former rats was significantly smaller than that in the latter (p<0.01). Vmean of actin transport in GBe-treated diabetic rats was significantly faster than that in untreated diabetic rats (p<0.05). Vmean of slow axonal transport was significantly correlated with mean diameter of axons in the three groups of rats combined (p<0.01). On electron microscopy, severe altered endoneurial microvessels decreasing in luminal area together with endothelial cell degeneration or hypertrophy, pericyte debris and basement membrane thickening were observed in untreated diabetic rats; on the other hand these findings were less prominent in the diabetic rats treated with GBe. It is suggested that GBe treatment may protect disturbed slow axonal transport and pathological alterations of peripheral nerve with abnormal endoneurial microvasculature from diabetes mellitus by antioxidant activity.

    ABSTRACT: The effect of daily walking on body fat distribution was investigated using an electronic pedometer and ultrasonography. Subjects were 77 women, aged 31 to 72 years. They were divided into four groups according to the average number of steps they walked per day (I<7,500, 7,500 ≤II<10,000, 10,000 <III<12,500, 12,500 ≤IV). Subcutaneous fat in the trunk and limbs, and the minimum thickness of subcutaneous fat (Smin) and the maximum thickness of preperitoneal fat (Pmax) below the xiphoid process were measured by ultrasonography. Abdominal wall fat index (AFI) reflecting the intra-abdominal fat accumulation was obtained by dividing Pmax by Smin. Fat distribution was analyzed by ANCOVA, controlled for age, body mass index (BMI), percent body fat, and menopausal status. Energy and macronutrient intake were obtained through a nutritional survey. There were no significant differences in anthropometric variables, energy and macronutrient intake, and subcutaneous fat thickness in trunk and limbs. Pmax of Group I was significantly higher than Group IV. Furthermore, Group I showed significantly higher AFI than the other three Groups (II, III, IV). The results of this study suggested that women who walked less than 7,500 steps per day tend to have significantly increased intra-abdominal fat accumulation.

    ABSTRACT: There is a general recognition of the role of low birthweight (LBW) as a major determinant of infant mortality rates. Since the rate of LBW has been increasing over the past fifteen years in Japan, we decided to ascertain the risk factors related to it, and also to verify whether or not maternal leisure-time physical activities including sports activities, before pregnancy and during gestation, affected the rate of LBW babies. In our study of the 2,682 questionnaires delivered within a year to the Municipal Health Centers of the three cities chosen for this study, 1,714 questionnaires were analyzed. The results in a univariate analysis showed that maternal height, pre-pregnancy weight, length of gestation, smoking, hospitalization before the 37th week of gestation, a history of LBW, and occupational activities were significantly associated with LBW. In logistic regression analyses, mothers of smaller stature, less pre-pregnancy weight, less length of gestation and mothers who were, furthermore, hospitalized before the 37th week of gestation, smoked, had previously delivered a LBW baby or had experienced stressful events during pregnancy were more likely to have LBW babies. The results showed that maternal leisure-time physical activities before and/or during pregnancy had no bearing on the delivery of a LBW baby.

    ABSTRACT: Analysis of policy functions, with a focus on their major participants, elicits a clear picture of the decision-making process for smoking control in Japan. Activities of various advocacy groups have affected the functions of policy, including: Intelligence, Promotion, Prescription, Invocation, Application and Appraisal. In fulfilling these functions, they have affected every issue they faced by creating, transforming and propagating information in line with their interests and by influencing government decisions using coalition-building and the lobbying of elected officials. Furthermore, they have determined the development and implementation of various programs, even assuming key roles in substantiating the decisions. On the other hand, political leverage by the tobacco industry, exercised through various policy functions, intimidated the government leadership and eventually controlled its actions. When the nonsmokers’ rights groups emerged, they gradually started to take part in policy functions, sometimes in cooperation with the health agency. The initial and final forms of smoking control policies in society have been deeply affected by the involvement of these groups.

    ABSTRACT: To examine the relationships between anger expression and blood pressure (BP) levels and their effect modification by stress coping behaviors, the authors analyzed data from a cross-sectional study of 790 Japanese male workers aged 20–60 years. We used the Spielberger anger expression scales to measure anger-out, anger-in, and anger-control. Relationships between anger expression scales and mean systolic and diastolic BP levels were examined in the total sample and in two subgroups of high and low stress coping behaviors (low coping behavior group: having none, one, or two coping behaviors; and high coping behavior group: having three or more coping behaviors). Anger expression scales were not associated with BP levels in the total sample. Among men who reported only two or fewer coping behaviors, however, the anger-out score was significandy associated with systolic blood pressure (SBP) levels while no association was found among men who reported the larger number of coping behaviors. Anger-in and anger-control were not associated with BP levels in either low or high coping behavior groups. This study suggests that male workers who do not express their anger have a higher probability of developing high BP when they have no or few stress coping behaviors.

    ABSTRACT: The physical status and serum mineral concentrations for people aged 10 to 68 years living in an agricultural southern region of Nepal were determined. Systolic (SBP) and diastolic blood pressure (DBP) for both sexes in the 10–14 year age group were low (p<0.05. vs the other age groups) and those for the over 50-year-olds tended to be higher than the other age groups. The mean values of total proteins (TP) (8.6 ± 0.5 g/dl for males and 8.7 ± 0.6 g/dl for females) were high due to an increase of globulin (3.9 ± 0.4 g/dl for males and 4.1 ± 0.5 g/dl for females). More than three-fourths of the subjects of both sexes showed calcium (Ca) levels of 9.0–11.2 mg/dl and about 65% of them showed potassium (K) levels of 4.8–5.4 mEq/1. A significant positive correlation between DBP and serum K was observed (p<0.05). Serum inorganic phosphorus (IP) correlated with age (p<0.001) and body mass index (BMI) (p<0.001). The serum Ca levels correlated with TP (r=0.31, p<0.001), albumin (Alb) (r=0.50, p<0.001), IP (r=0.31, p<0.001), K (r=0.32, p<0.001) and chlorine (Cl)(r=-0.37, p<0.001). Cl was associated with TP (r=-0.21, p<0.05), Alb (r=-0.36, p<0.001) and IP (r=-0.21, p<0.05). These results suggested that Ca intake for the subjects seemed to be insufficient although their serum Ca level was within normal.

    ABSTRACT: We have attempted to upgrade and validate an in-house cDNA microarray system developed by our group for the evaluation of chemical toxicity. To establish an in-house microarray, we selected genes that play pivotal roles in detoxifying exogenous substances and maintaining homeostasis in the liver. To validate the system, we examined gene expression profiles in mouse liver following treatment with different doses of carbon tetrachloride (CCl(4)). The data were also analyzed by pathway analysis tools. We upgraded our array system by collecting genes that are responsive to xenobiotic receptors, apoptosis-related genes, and stress-responsive genes. The acute toxicity of CCl(4) was confirmed by elevated levels of serum transaminase and histopathological findings. The microarray data showed the CCl(4) treatment induced significant changes in gene expression in the mouse liver, and the ingenuity pathways analysis revealed alterations in gene expression in inflammation-related networks. We have established a focused microarray system that may be useful for use in toxicogenomics studies. Using this array system, we gained insight into the mechanisms by which CCl(4) exerts its toxic effects. The results of our study also indicate that the combination of focused arrays and bioinformatics tools is helpful in the mechanistic analysis of chemical toxicity.

    ABSTRACT: Chronic infection and inflammation contribute to a substantial part of environmental carcinogenesis. Recently, it has been estimated that chronic inflammation accounts for approximately 25% of cancer cases. Various infectious diseases and physical, chemical, and immunological factors participate in inflammation-related carcinogenesis. Under inflammatory conditions, reactive oxygen and nitrogen species, which are generated from inflammatory and epithelial cells, may play an important role in carcinogenesis by causing DNA damage. 8-Nitroguanine is a mutagenic DNA lesion formed during chronic inflammation. In an earlier publication, our group reported the results of an immunohistochemical analysis of animals infected with the liver fluke Opisthorchis viverrini and demonstrated for the first time that 8-nitroguanine was formed at the sites of carcinogenesis. This DNA lesion was found to accumulate in the carcinogenic process in clinical specimens of cancer-prone inflammatory diseases caused by various pathogens, including human papillomavirus and Epstein-Barr virus. Moreover, strong 8-nitroguanine formation in tumor tissues was closely associated with a poor prognosis. On the basis of these findings, 8-nitroguanine could be a potential biomarker to evaluate the risk of inflammation-related carcinogenesis and the prognosis of cancer patients. In this review, the significance of 8-nitroguanine formation in inflammation-related carcinogenesis and tumor progression will be discussed.
