In both main mol-ecules, the pyrrolidine rings are in an envelope conformation with a methyl-ene C atom as the flap. The morpholine rings adopt chair conformations. Both benzimidazole rings are essentially planar, with maximum deviations of 0.008 (1) A, and form dihedral angles of 37.65 (6) and 45.44 (6) degrees with the benzene rings. In one mol-ecule, an intra-molecular C-Hcdots, three dots, centeredO hydrogen bond forms an S(7) ring motif. In the crystal, O-Hcdots, three dots, centeredO and O-Hcdots, three dots, centeredN hydrogen bonds connect pairs of main mol-ecules and pairs of water mol-ecules into two independent centrosymmetric four-compoment aggregates. These aggregates are connect by C-Hcdots, three dots, centeredO hydrogen bonds leading to the formation of a three-dimensional network, which is stabilized by C-Hcdots, three dots, centeredpi interactions.

DESIGN: A cross-sectional study utilized data from University of Houston students through an online survey (n = 2334) from March to April 2011. The survey included questions on demographic characteristics (sex, age, race/ethnicity), tobacco use experience, risk perception, social acceptability and popularity. Multivariate logistic regression was used to determine predictors of waterpipe use with three outcomes: ever-use vs. no use, past-year use vs. no use and past-month use vs. no use. RESULTS: Half of the sample had previously smoked tobacco using a waterpipe, approximately a third in the past year and 12.5% in the past month. Significant predictors included Middle Eastern ethnicity, Middle Eastern friend, past cigarette or cigar use. Perception of harm was associated with less use in the ever-use model, while perceived addictiveness, social acceptability and popularity of waterpipes were predictors in all models. CONCLUSION: Our findings underscore the importance of developing culturally appropriate interventions to control waterpipe smoking among Middle Eastern Americans and those of Indian/Pakistani descent to curb further spread in US society, and highlight the importance of developing interventions that target the perceived addictiveness, social acceptability and popularity of waterpipe smoking.

However, data on the influence of the mode of collection of data on self-reporting are limited. The aim of the study was to identify associations between the mode of data collection and self-reported smoking in two distinct ethnic groups, Jews and Arabs in Israel. During the last 2 years, data were collected in two national surveys regarding the smoking behaviors of Jews and Arabs in Israel. In the telephone surveys 4713 Israeli residents were interviewed and in the face-to-face interviewees 3239 people were interviewed. The interviewees were between the ages 25 and 64. There was no significant difference in smoking rates between face-to-face interviews and telephone interviews among Jewish men or women after adjusting for other variables associated with smoking. However, there was a difference between the two methods of data collection in the Arab population also after the adjustment. In this group, respondents tended to report more often being a smoker in the face-to-face interviews. This was especially apparent in Arab women. There was no significant difference in the reported number of cigarettes smoked in the two modes of data collection. In Arabs compared to Jews there is a significant difference between reporting smoking during a telephone interview and a face-to-face interview. The mode of data collection can affect comparisons between different groups.

Since most adult smokers began smoking in childhood, understanding behavorial factors associated with smoking initiation would contribute to smoking initiation programs. Health-related behavior may vary between different ethnic groups. OBJECTIVES: To determine the prevalence of smoking among Jewish and Arab adolescents in Jerusalem, and whether there are differences in smoking initiation between the two ethnic groups. METHODS: We carried out a cross-sectional survey of all students in the 6th to 11th grades (age range 11-17 years) of a Jewish school and an Arab school in the Jerusalem area, using an anonymous self-completion questionnaire. A total of 791 questionnaires was analyzed, 479 from the Jewish students and 312 from the Arab students. RESULTS: The lowest prevalence of smoking was found among Arab female students and the highest among Jewish female students (9% vs. 41%, P < 0.001). The prevalence of smoking among Jewish and Arab males was similar. More Arab female students smoked than their mothers. Peer pressure seemed to be a more important factor among Jewish students. CONCLUSIONS: This study demonstrated the presence of ethnic differences in smoking prevalence and the reasons for smoking among adolescents in Israel. These results suggest the need for specific smoking prevention policies for different ethnic groups.

DESIGN: A self-administered survey of demographics, tobacco use, and other health risk behaviors was administered at the start of basic military training. SETTING: The study was conducted at Lackland Air Force Base, San Antonio, Texas, where all U.S. Air Force recruits complete basic military training. SUBJECTS: All recruits who entered the U.S. Air Force between September 1995 and September 1996 participated in this study (n = 32,144; 100% participation rate). MEASURES: Recruits completed a written 53-item behavioral risk questionnaire. Measures examined in the present study included smoking status (ever having smoked a cigarette, current daily smoking, and quitting); demographics (ethnicity, gender, education, family income, and age); smoking history; and nicotine dependence. RESULTS: Rates of ever smoking, current daily smoking, and quitting were examined in multiple logistic regression analyses as a function of gender and ethnicity, controlling for age, education, and family income. Overall, 54% of recruits had ever smoked a cigarette and 24.9% smoked daily at the time of entry into basic military training. Smoking rates were highest among white and Native American recruits. Among whites, women were more likely to be a current daily smoker (31.6% vs. 29.4%; odds ratio [OR] = 1.18, 99% confidence intervals [CI] = 1.08-1.29). The opposite pattern was observed among African-Americans (5.6% vs. 9.8%, respectively; OR = .57; CI = .41-.79). Current smokers had low levels of nicotine dependence compared with the general population of U.S. smokers, but whites tended to be more dependent than other ethnic groups. Cessation rates were similar for men and women but differed according to ethnicity, ranging from 15% among whites to 23% among Hispanics. CONCLUSIONS: These findings document important gender and ethnic differences in cigarette smoking among military recruits. Whites and Native Americans were more likely to smoke, less likely to quit, and more nicotine-dependent than other ethnic groups. Across gender/ethnicity groups, smoking rates were especially high among white women, with nearly one-third smoking daily until entry into basic training. Gender differences were not observed in cessation rates, but Hispanics were more likely than other ethnic groups to have quit smoking. The results highlight the need to develop effective cessation interventions for this population.

MATERIALS AND METHODS: Human premolars that had been extracted for orthodontic purposes were used. Enamel was etched with an Er,Cr:YSGG laser system operated at one of three power outputs or with orthophosphoric acid. RESULTS: The shear bond strength associated with the 0.5-W laser irradiation was significantly less than the strengths obtained with the other irradiations. Both the 1-W and 2-W laser irradiations were capable of etching enamel in the same manner. This finding was confirmed by scanning electron microscopy examination. The evaluation of adhesive-remnant-index scores demonstrated no statistically significant difference in bond failure site among the groups, except for the 0.5-W laser-etched group. Generally, more adhesive was left on the enamel surface with laser irradiation than with acid etching. CONCLUSION: The mean shear bond strength and enamel surface etching obtained with an Er,Cr: YSGG laser (operated at 1 W or 2 W for 15 seconds) is comparable to that obtained with acid etching.

BMC Public Health Pub Date Free Form Volume 4 Issue Start Page 32 Other Pages 32 Notes ID: 15294023 Place of Publication ISSN/ISBN Accession Number Language en SubFile DOI Output Language Unknown(0) PMID Abstract BACKGROUND: Waterpipe smoking is becoming a global public health problem, especially in the Eastern Mediterranean region (EMR). METHODS: We try in this study, which is a cross sectional survey among a representative sample of waterpipe smokers in cafes/restaurants in Aleppo-Syria, to assess the time period for the beginning of this new smoking hype. We recruited 268 waterpipe smokers (161 men, 107 women; mean age +/- standard deviation (SD) 30.1 +/- 10.2, response rate 95.3%). Participants were divided into 4 birth cohorts (1980) and year of initiation of waterpipe smoking and daily cigarette smoking were plotted according to these birth cohorts. RESULTS: Data indicate that unlike initiation of cigarette smoking, which shows a clear age-related pattern, the nineties was the starting point for most of waterpipe smoking implicating this time period for the beginning of the waterpipe epidemic in Syria. CONCLUSION: The introduction of new flavored and aromatic waterpipe tobacco (Maassel), and the proliferation of satellite and electronic media during the nineties may have helped spread the new hype all over the Arab World.
