However, little empirical data indicate how SHS is distributed throughout homes and whether smoking in segregated areas offers protection. This project studied real-time data on levels of SHS in 9 homes in which smoking was permitted and in 3 smoke-free homes. Active sampling monitors were used to assess levels of PM(2.5), a marker for SHS, over a 3-day period. In smoking homes, one monitor was placed in the primary smoking area and another in a distal location, where smoking generally did not occur. Participants logged smoking and other activities that could affect air quality. In smoking homes, without assuming normality, the mean PM(2.5) level for the primary smoking areas was statistically significantly higher than that for distal areas (84 and 63 microg/m3, respectively). Both levels far surpassed the U.S. Environmental Protection Agency's annual standard of 15 microg/m3 for outdoor air quality. By contrast, the smoke-free home mean was 9 microg/m3, similar to outdoor air quality. These results suggest that the air in smoking homes was several times more polluted than that in smoke-free homes, regardless of where the measurements were taken, meaning that efforts to confine smoking to only part of the home offer no protection for people anywhere inside the home. Household members can be protected by implementing a smoke-free home policy.

METHODS: Eighty freshly extracted maxillary premolars were randomly divided into 4 groups (20 in each group). In all groups, the teeth were etched with 37% phosphoric acid for 20 seconds, and RMGIC (Fuji Ortho LC, GC Europe, Leuven, Belgium) was used for bracket bonding. In groups 1 and 3, the brackets were bonded directly to etched enamel surfaces; in groups 2 and 4, the etched enamel was covered with HFLCS (Pro Seal, Reliance Orthodontic Products, Itasca, Ill). Groups 1 and 2 received metal brackets, and groups 3 and 4 had ceramic brackets. The specimens were stored in distilled water at room temperature for 24 hours and subsequently tested in shear mode with a universal testing machine. After debonding, the teeth and the brackets were examined under a stereomicroscope (model SMZ-1B, Nikon, Osaka, Japan) at 20-times magnification to assess the residual adhesive on the tooth surfaces. RESULTS: Interaction between HFLCS and bracket type was not statistically significant (P = 0.15). Pretreatment with HFLCS did not cause a statistically significant change in the shear bond values of either metal or ceramic brackets (P = 0.38). Shear bond values of the ceramic brackets were higher than those of the metal brackets independent of HFLCS application (P <0.001). No significant differences were found in bond failure modes in the 4 groups. CONCLUSIONS: HFLCS application on enamel etched with 37% phosphoric acid did not affect the bond strength values and the bond failure modes of metal and ceramic brackets bonded with RMGIC. RESULTS: Interaction between HFLCS and bracket type was not statistically significant (P = 0.15).

Cigarette smoking was statistically significantly higher in WP smokers than non-WP smokers; 36.5% of exclusive WP smokers smoked > or =7 WPs/week. Chronic respiratory disease and chronic bronchitis were reported more frequently in exclusive WP smokers than absolute non-smokers. WP smoking seems to be as great a risk factor as cigarette smoking for chronic respiratory disease.

The best pharmacophore model, Hypo1, which has the highest correlation coefficient (0.9911), consists of one hydrogen-bond acceptor, one hydrogen-bond donor, one hydrophobic aliphatic moiety and one ring aromatic feature. Hypo1 was validated by test set and cross-validation methods. And the specificity of Hypo1 to Aurora B inhibitors was examined with the use of selective inhibitors against Aurora B and its paralogue Aurora A. The results clearly indicate that Hypo1 can differentiate selective inhibitors of Aurora B from those of Aurora A, and the ring aromatic feature likely plays some important roles for the specificity of Hypo1. Then Hypo1 was used as a 3D query to screen several databases including Specs, NCI, Maybridge and Chinese Nature Product Database (CNPD) for identifying new inhibitors of Aurora B. The hit compounds were subsequently subjected to filtering by Lipinski's rule of five and docking studies to refine the retrieved hits, and some compounds selected from the top ranked hits have been suggested for further experimental assay studies.

Pub Date Free Form Volume 16 Issue 2 Start Page 38 Other Pages 90 Notes ID: 19770234 Place of Publication ISSN/ISBN Accession Number Language en SubFile DOI Output Language Unknown(0) PMID Abstract Tobacco use is the leading preventable cause of death and disease in the world; yet little is known about the levels or patterns of youth tobacco use on a global basis. The purpose of this paper is to focus on change in youth tobacco use using data from 100 sites that have conducted repeat Global Youth Tobacco Surveys (GYTS). The GYTS is a school-based survey that collects data from students aged 13-15 years using a standardized methodology for constructing the sample frame, selecting schools and classes, and processing data. GYTS is conducted in school classes using self-administered anonymous data collection. The GYTS sample produces representative, independent, cross-sectional estimates for each sampling frame. Of the 100 sites surveyed, 61 reported no change over time in prevalence of cigarette smoking, likewise in 50 of the 97 sites with data on use of other tobacco products there was no change. However, 34 sites reported an increase in other tobacco use. This appears to be attributed to waterpipe, an emerging trend in tobacco use. Evidence was found supporting the idea that tobacco use among adolescent girls is likely increasing. The global tobacco control effort continues to face many challenges in reversing the tobacco epidemic. Few countries have implemented comprehensive tobacco control legislation laid out by the World Health Organization. The few countries that have adopted some of these proven policies can serve as examples in achieving positive results in curbing the tobacco epidemic.

Mobile phones are widely used and are now well integrated into the daily lives of many, particularly young adults. Mobile phones are a potential medium for the delivery of health programmes such as smoking cessation. OBJECTIVES: To determine whether mobile phone-based interventions are effective at helping people who smoke, to quit. SEARCH STRATEGY: We searched MEDLINE, EMBASE, Cinahl, PsycINFO, The Cochrane Library, the National Research Register and the ClinicalTrials register, with no restrictions placed on language or publication date. SELECTION CRITERIA: We included randomized or quasi-randomized trials. Participants were smokers of any age who wanted to quit. Studies were those examining any type of mobile phone-based intervention. This included any intervention aimed at mobile phone users, based around delivery via mobile phone, and using any functions or applications that can be used or sent via a mobile phone. DATA COLLECTION AND ANALYSIS: Information on the specified quality criteria and methodological details was extracted using a standardised form. Participants who dropped out of the trials or were lost to follow up were considered to be smoking. Meta-analysis of the included studies was undertaken using the Mantel-Haenszel Risk Ratio fixed-effect method provided that there was no evidence of substantial statistical heterogeneity as assessed by the I(2) statistic. Where meta-analysis was not possible, summary and descriptive statistics are presented. MAIN RESULTS: Four studies were excluded as they were small non-randomized feasibility studies, and two studies were excluded because follow up was less than six months. Four trials (reported in five papers) are included: a text message programme in New Zealand; a text message programme in the UK; and an Internet and mobile phone programme involving two different groups in Norway. The different types of interventions are analysed separately. When combined by meta-analysis the text message programme trials showed a significant increase in short-term self-reported quitting (RR 2.18, 95% CI 1.80 to 2.65). However, there was considerable heterogeneity in long-term outcomes, with the much larger trial having problems with misclassification of outcomes; therefore these data were not combined. When the data from the Internet and mobile phone programmes were pooled we found statistically significant increases in both short and long-term self-reported quitting (RR 2.03, 95% CI 1.40 to 2.94). AUTHORS' CONCLUSIONS: The current evidence shows no effect of mobile phone-based smoking cessation interventions on long-term outcome. While short-term results are positive, more rigorous studies of the long-term effects of mobile phone-based smoking cessation interventions are needed.

The Framework Convention on Tobacco Control (FCTC) aims to address this problem in Article 11 which deals with misleading labelling of tobacco products. In this study we aimed to determine smokers' use and beliefs concerning "light" and "mild" cigarettes ("lights"), including in relation to ethnicity, deprivation and other socio-demographic characteristics. METHODS: The New Zealand (NZ) arm of the International Tobacco Control Policy Evaluation Survey (ITC Project) uses as its sampling frame the NZ Health Survey. This is a national sample with boosted sampling of Maori, Pacific peoples and Asians. From this sample we surveyed adult smokers (n = 1376) about use and beliefs relating to "light" cigarettes. We assessed the associations with smoking "lights" after adjusting for socio-demographic variables, and smoking-related behaviours and beliefs. RESULTS: Many smokers of "lights" believed that smoking "lights" made it easier to quit smoking (25%), that "lights" are less harmful (42%), and that smokers of "lights" take in less tar (43%). Overall most "lights" smokers (60%) had at least one of these three beliefs, a proportion significantly higher than for smokers of "regular" cigarettes at 45% (adjusted odds ratio (aOR) = 1.96, 95% CI = 1.29 - 2.96). While "lights" smokers had significantly lower tobacco consumption and were more aware of smoking harms, they were no more likely to be intending to quit or have made a previous quit attempt. By ethnicity, both Maori and Pacific people were less likely to smoke "lights" than Europeans (aOR = 0.53, 95% CI = 0.35 - 0.80 and aOR = 0.14, 95% CI = 0.05 - 0.40 respectively). In contrast there was no significant difference by level of deprivation. Roll-your-own (RYO) tobacco smokers were less likely to smoke "light" forms of RYO tobacco while both older and women smokers were more likely to smoke "lights". CONCLUSION: Most "lights" smokers have one or more misperceptions about the product they use, and were no more likely to intend to quit or to have made a quit attempt. In response to such misperceptions, governments could act further to eliminate all misleading tobacco marketing. Ideally, they could not only adopt FCTC requirements, but go further by requiring plain packaging for all tobacco products.

Chinese men are at high risk for smoking-related morbidity and mortality. We tested the feasibility of a culturally and linguistically sensitive smoking intervention program with combined counseling and pharmacological components for Chinese smokers in New York City; identified factors and techniques that enhance the administration and appropriateness of the intervention program; and examined the overall impact of this program on quit attempts, quit rates, and overall smoking reduction. METHODS: We were guided by the transtheoretical model and used an adapted motivational interviewing (MI) approach. The study involved a randomized sample with pretreatment assessment and multiple follow-up measures. Eligible participants (N = 122) were randomly assigned to intervention (4 individualized counselor-led MI sessions and nicotine replacement therapy [NRT]) or control groups (4 general health education sessions, self-help materials, and NRT). RESULTS: Quit rate at 6 months in the intervention group was 67% versus 32% for the control group, indicating minimal relapse and a highly successful intervention program. Increase in self-efficacy and decease in pros of smoking from baseline to 6-month follow-up were positively associated with smoking cessation. The number of cigarette smoked at baseline was inversely related to smoking cessation. Results indicate that a combined intensive behavioral counseling and pharmacological intervention can reduce smoking substantially. CONCLUSION: The results of this pilot will be used as a basis for a large-scale randomized trial of an intervention with combined culturally and linguistically sensitive MI and NRT components for Chinese and other Asian ethnic groups.

Smoking during pregnancy has detrimental effects on asthma-associated outcomes in childhood. Whether passive exposure of pregnant women to ETS may also lead to asthma in their offspring, is not known. The aim of this study was to investigate the association of passive exposure of pregnant women to ETS and asthma- and/or allergy-related symptoms in Preschool children. Cross-sectional data were collected with questionnaires from 2374 Preschool children, recruited from public and private nurseries and day-care centers. Parental smoking was significantly associated with wheezing symptoms in their children. Mother's active smoking during pregnancy significantly increased the risk for occurrence of asthma symptoms and/or medically diagnosed asthma in Preschool children in a dose-dependent manner. Passive exposure to ETS, mainly during the third trimester of pregnancy, was significantly associated with asthma- and allergy-related symptoms after adjusting for several confounders in a multivariate analysis (current wheeze: OR = 1.42, 95% CI = 1.06-1.91, pruritic rash ever: OR= 1.45, 95% CI = 1.01-2.08). Passive exposure of pregnant women to ETS during the third trimester is positively associated with asthma- and allergy-related symptoms in their Preschool age children. Public health policies should be oriented not only towards smoking cessation, but also reinforce elimination of ETS exposure of pregnant women.

In this method, no specific holder, such as the needle tip of microsyringe and the hollow fiber, is required for supporting the organic microdrop due to the using of organic solvent with low density and proper melting point. Furthermore, the extractant droplet can be collected easily by solidifying it in the lower temperature. 1-Dodecanol was chosen as extraction solvent in this work. A series of parameters that influence extraction were investigated systematically. Under optimal conditions, enrichment factors (EFs) for PAHs were in the range of 88-118. The limit of detections (LODs) for naphthalene, diphenyl, acenaphthene, anthracene and fluoranthene were 0.045, 0.86, 0.071, 1.1 and 0.66ngmL(-1), respectively. Good reproducibility and recovery of the method were also obtained. Compared with the traditional liquid-phase microextraction (LPME) and dispersive liquid-liquid microextraction (DLLME) methods, the proposed method obtained about 2 times higher enrichment factor than those in LPME. Moreover, the solidification of floating organic solvent facilitated the phase transfer. And most importantly, it avoided using high-density and toxic solvent in the traditional DLLME method. The proposed method was successfully applied to determinate PAHs in the environmental water samples. The simple and low-cost method provides an alternative method for the analysis of non-polar compounds in complex environmental water.
