Abstract
INTRODUCTION: The aim of this study was to evaluate and compare the in vitro effect of the Erbium-Doped Yttrium Aluminum Garnet (Er:YAG) laser with different radiation distances and high-speed rotary treatment on the shear bond strength of flowable composite to enamel of human permanent posterior teeth. METHODS: freshly extracted human molar teeth with no caries or other surface defects were used in this study (n=45). The teeth were randomly divided into 3 groups. Group 1: treated with non-contact Er:YAG Laser and etched with Er:YAG laser, Group 2: treated with contact Er:YAG Laser and etched with Er:YAG laser, Group 3 (control): treated with diamond fissure bur and etched with acid phosphoric 37%. Then the adhesive was applied on the surafces of the teeth and polymerized using a curing light appliance. Resin cylinders were fabricated from flowable composite. Shear bond strength was tested at a crosshead speed of 0.5 mm/min. RESULTS: The amount of Shear Bond Strength (SBS) in the 3 treatment groups was not the same (P

Abstract
BACKGROUND: We compared the validity of the Cigarette Dependence Scale (CDS-12) and of the Fagerstrom Test for Nicotine Dependence (FTND) in daily cigarette smokers. METHODS: Internet survey in 2004-2007. Eight days and 6 weeks after answering these two dependence questionnaires, participants indicated their smoking status and answered the Cigarette Withdrawal Scale and the Smoking Self-Efficacy Questionnaire. We used the Mini International Neuropsychiatric Interview (MINI) to assess nicotine dependence as defined in DSM-IV. RESULTS: There were 13,697 participants at baseline, 1113 (8%) after 8 days and 435 (3%) after 6 weeks. CDS-12, but not FTND, predicted smoking cessation after 8 days (odds ratio=1.20 per standard deviation unit, p=0.03) and 6 weeks (odds ratio=1.34, p=0.01). In participants who had quit smoking after 8 days, CDS-12 was a better predictor of craving (beta=0.30, p<0.001), than FTND (beta=0.14, p<0.01). After 8 days, self-efficacy in quitters was predicted by CDS-12 (beta=-0.16, p=0.02), but not by FTND (beta=-0.05, p=0.3). CDS-12 was more strongly associated than FTND with DSM-defined dependence measured by MINI: area under the Receiver Operating Characteristic (ROC) curve=0.72 (95% confidence interval=0.70-0.73). For FTND, the area under ROC=0.64 (0.63-0.66). CONCLUSIONS: CDS-12 performed better than FTND on tests of predictive and construct validity.

Abstract
BACKGROUND: Smoking cessation remains a significant public health problem. Innovative interventions that use the Internet have begun to emerge that offer great promise in reaching large numbers of participants and encouraging widespread behavior change. To date, the relatively few controlled trials of Web-based smoking cessation programs have been limited by short follow-up intervals. OBJECTIVE: We describe the 6-month follow-up results of a randomized controlled trial in which participants recruited online were randomly assigned to either a Web-based smoking cessation program (Quit Smoking Network; QSN) or a Web-based exercise enhancement program (Active Lives) adapted somewhat to encourage smoking cessation. METHODS: The study was a two-arm randomized controlled trial that compared two Web-based smoking cessation programs: (1) the QSN intervention condition presented cognitive-behavioral strategies, and (2) the Active Lives control condition provided participants with guidance in developing a physical activity program to assist them with quitting. The QSN condition provided smoking cessation information and behavior change strategies while the Active Lives condition provided participants with physical activity recommendations and goal setting. The QSN condition was designed to be more engaging (eg, it included multimedia components) and to present much greater content than is typically found in smoking cessation programs. RESULTS: Contrary to our hypotheses, no between-condition differences in smoking abstinence were found at 3- and 6-month follow-up assessments. While participants in the QSN intervention condition spent more time than controls visiting the online program, the median number of 1.0 visit in each condition and the substantial attrition (60.8% at the 6-month follow-up) indicate that participants were not as engaged as we had expected. CONCLUSIONS: Contrary to our hypothesis, our test of two Web-based smoking cessation conditions, an intervention and an attention placebo control, failed to show differences at 3- and 6-month assessments. We explored possible reasons for this finding, including limited engagement of participants and simplifying program content and architecture. Future research needs to address methods to improve participant engagement in online smoking cessation programs. Possible approaches in this regard can include new informed consent procedures that better explain the roles and responsibilities of being a research participant, new program designs that add more vitality (changing content from visit to visit), and new types of reminders pushed out to participants to encourage return visits. Simplifying program content through a combination of enhanced tailoring and information architecture also merits further research attention.

Abstract
INTRODUCTION: One possible reason for the rapid proliferation of waterpipe (WP) smoking is the pervasive use of flavoured WP tobacco. To begin to understand the impact of WP tobacco flavours, the current study examined the impact of a preferred WP tobacco flavour compared with a non-preferred tobacco flavoured control on user's smoking behaviour, toxicant exposure and subjective smoking experience. METHOD: Thirty-six current WP smokers completed two, 45-minute ad libitum smoking sessions (preferred flavour vs non-preferred tobacco flavour control) in a randomised cross-over design. Participants completed survey questionnaires assessing subjective smoking experience, exhaled carbon monoxide (eCO) testing, and provided blood samples for monitoring plasma nicotine. WP smoking topography was measured continuously throughout the smoking session. RESULTS: While participants reported an enhanced subjective smoking experience including greater interest in continued use, greater pleasure derived from smoking, increased liking and enjoyment, and willingness to continue use after smoking their preferred WP tobacco flavour (p values

Abstract
In this work, two disperser-free microextraction methods, namely, air-agitated liquid-liquid microextraction and ultrasound-assisted emulsification microextraction are compared for the determination of a number of polycyclic aromatic hydrocarbons in aqueous samples, followed by gas chromatography with flame ionization detection. The effects of various experimental parameters upon the extraction efficiencies of both methods are investigated. Under the optimal conditions, the enrichment factors and limits of detection were found to be in the ranges of 327-773 and 0.015-0.05 ng/mL for air-agitated liquid-liquid microextraction and 406-670 and 0.015-0.05 ng/mL for ultrasound-assisted emulsification microextraction, respectively. The linear dynamic ranges and extraction recoveries were obtained to be in the range of 0.05-120 ng/mL (R(2) >/= 0.995) and 33-77% for air-agitated liquid-liquid microextraction and 0.05-110 ng/mL (R(2) >/= 0.994) and 41-67% for ultrasound-assisted emulsification microextraction, respectively. To investigate this common view among some people that smoking hookah is healthy due to the passage of smoke through the hookah water, samples of both the hookah water and hookah smoke were analyzed.

Abstract
Two micro-extraction methods, air-agitated liquid-liquid microextraction (AALLME) and dispersive liquid-liquid microextraction (DLLME), have been compared with each other by applying them for the analysis of five triazole pesticides (penconazole, hexaconazole, diniconazole, tebuconazole and triticonazole) in aqueous samples by gas chromatography with flame ionization detection (GC-FID). In the AALLME method, which excludes any disperser solvent, much less volume of organic solvent is used. In order to form fine and dispersed organic droplets in the aqueous phase, the mixture of aqueous sample solution and extraction solvent is repeatedly aspirated and dispensed with a syringe. In the DLLME method, an appropriate mixture of extraction solvent and disperser solvent is rapidly injected by a syringe into the aqueous sample. Effect of the pertinent experimental factors on DLLME (i.e. identity and volume of the extraction and disperser solvents and ionic strength) and on AALLME (identity and volume of the extraction solvent, number of agitations, and ionic strength) were investigated. Under optimal conditions, limits of detection for the five target pesticides obtained by AALLME-GC-FID and DLLME-GC-FID ranged from 0.20 to 1.1ngmL(-1) and 1.9 to 5.9ngmL(-1), respectively. The relative standard deviations (RSDs, n=5) were in the range of 1-4% and 3-5% with the enrichment factors of 449-504 and 79-143 for AALLME-GC-FID and DLLME-GC-FID, respectively. Both of the compared methods are simple, fast, efficient, inexpensive and can be applied to the analysis of the five pesticides in different aqueous samples in which penconazole and hexaconazole were found. For spiked samples, the recoveries were in the ranges of 92-105%, and 92-104% for AALLME and DLLME, respectively.

Abstract
This cross-sectional study examined the differences in barriers to cessation and reasons for quitting smoking among dual smokers of cigarettes and waterpipe tobacco, exclusive cigarette smokers and exclusive waterpipe smokers. Participants were Arab American adults residing in Richmond, Virginia, who were recruited from Middle Eastern grocery stores, restaurants/lounges and faith and charity organizations. The study yielded several key findings: (1) Exclusive cigarette and waterpipe smokers had similar mean barriers to quitting and were more concerned about their health than dual smokers. (F(2, 150) = 5.594, p = 0.0045). This implies that barriers to smoking and health concerns could be a function of the individual who smokes rather than the modality of smoking itself. (2) Exclusive cigarette or waterpipe smokers and dual smokers may have different reasons for quitting, since they have different reasons for smoking. The proportion of smokers who endorsed smoking as a messy habit as the reason among exclusive cigarette smokers was 0.37, whereas the proportion among exclusive waterpipe smokers was 0.04 and among dual smokers 0.39. The difference in proportions is significant, chi2 (df = 2, N = 154) = 13.17, p = 0.0014. In summary, this study supports the need to further investigate dual cigarette and waterpipe smokers, as the study results indicate greater barriers to smoking cessation in this group. Recognition and understanding of these barriers among dual tobacco users would be important for any future tobacco intervention among waterpipe smokers.

Abstract
INTRODUCTION: E-cigarette use is rapidly increasing, especially among youth and young adults. We need to learn what factors are associated with uptake in e-cigarettes. One important set of predictors is beliefs about e-cigarettes' potential harms and benefits. METHODS: Online survey data were collected in July, 2014 from 527 U.S. adults from a nationally representative online panel (KnowledgePanel) who reported being aware of e-cigarettes. Participants were asked to rate 7 statements related to e-cigarettes harms or benefits (e.g., breathing vapors from other people's e-cigarettes is harmful to my health; vaping or using e-cigarettes can help people quit smoking regular cigarettes completely). Responses were categorized into agree, disagree, or no opinion. We compared the proportions of agreement between respondents who ever used e-cigarettes and those who had never used. Multinomial logistic regression was used to predict agree or no opinion versus disagree (base outcome) for each belief. Relative risk ratios (RRRs) are reported. The analyses were completed in December, 2014 and were weighted to match the general U.S. adult population. RESULTS: Agreement across the 7 beliefs ranged from 33% (vaping can help people quit smoking) to 56% (e-cigarettes make smoking look more acceptable to youth). Ever use of e-cigarettes was associated with lower relative risk of agreeing with statements about potential harms and higher relative risk of agreeing with statements about benefits (versus disagreeing) compared with never users. DISCUSSION: These findings provide timely data on beliefs about e-cigarettes between e-cigarette users and non-users to inform potential message topics for health campaign interventions.

Abstract
The incidence of serious fungal infections, particularly invasive Candida infections exhibit an increasing trend in the last decades since the number of patients receiving immunosuppressive treatment is increasing. This situation eventually results in an increment in resistance to antifungal agents. The aim of this study was to compare the standard broth microdilution (BMD) and E-test methods for antifungal susceptibility testing of Candida species isolated from blood cultures in our hospital, against fluconazole, voriconazole, caspofungin and amphotericin B. A total of 46 Candida strains isolated from the blood cultures by BACTEC 9000 (Becton Dickinson, USA) and identified by conventional techniques and API 20C AUX (BioMerieux, France) during January 2006-December 2007, were included into this study. The identification results of the isolates were as follows: C. albicans (23), C. parapsilosis (10), C. tropicalis (5), C. krusei (3), C. famata (2), C. glabrata (1), C. guilliermondii (1), C. kefyr (1). The antifungal susceptibilities were determined by BMD method described in Clinical and Laboratory Standards Institute M27-A3 document and E-test. Only two isolates (C. albicans and C. globrata) were found to be resistant to fluconazole with E-test but susceptible with BMD. The minimal inhibitory concentration (MIC) values of caspofungin were higher (MIC = 1-2 microg/ml) in C. parapsilosis compared to other Candida species using E-test. Only one C. albicans was resistant to voriconazole by E-test (MIC = 4 microg/ml), but it was susceptible by BMD (MIC = 0.08 microg/ml). Since definite resistance breakpoints do not yet exist for amphotericin B, MIC values were considered for amphotericin B and it was found that all strains had identical low MIC values (< 0.002-0.5). When E-test results were compared with the standard BMD results, MIC values were in agreement 80.4% for fluconazole, 84.7% for amphotericin B, 95.6% for voriconazole and 93.4% for caspofungin. These results indicated that the most frequently isolated Candida species among blood cultures was C. albicans, followed by C. parapsilosis and these isolates had low antifungal resistance rates. When voriconazol and caspofungin susceptibilities were considered, both E-test and BMD susceptibility results were in good aggreement in comparison to fluconazol and amphotericin B. E-test can be considered as a compatible method for the antifungal susceptibility testing of Candida species compared to standard broth microdilution method.

Abstract
The lack of scientific evidence on the constituents, properties, and health effects of second-hand waterpipe smoke has fueled controversy over whether public smoking bans should include the waterpipe. The purpose of this study was to investigate and compare emissions of ultrafine particles (UFP, <100 nm), carcinogenic polyaromatic hydrocarbons (PAH), volatile aldehydes, and carbon monoxide (CO) for cigarettes and narghile (shisha, hookah) waterpipes. These smoke constituents are associated with a variety of cancers, and heart and pulmonary diseases, and span the volatility range found in tobacco smoke.Sidestream cigarette and waterpipe smoke was captured and aged in a 1 m(3) Teflon-coated chamber operating at 1.5 air changes per hour (ACH). The chamber was characterized for particle mass and number surface deposition rates. UFP and CO concentrations were measured online using a fast particle spectrometer (TSI 3090 Engine Exhaust Particle Sizer), and an indoor air quality monitor. Particulate PAH and gaseous volatile aldehydes were captured on glass fiber filters and DNPH-coated SPE cartridges, respectively, and analyzed off-line using GC-MS and HPLC-MS. PAH compounds quantified were the 5- and 6-ring compounds of the EPA priority list. Measured aldehydes consisted of formaldehyde, acetaldehyde, acrolein, methacrolein, and propionaldehyde.We found that a single waterpipe use session emits in the sidestream smoke approximately four times the carcinogenic PAH, four times the volatile aldehydes, and 30 times the CO of a single cigarette. Accounting for exhaled mainstream smoke, and given a habitual smoker smoking rate of 2 cigarettes per hour, during a typical one-hour waterpipe use session a waterpipe smoker likely generates ambient carcinogens and toxicants equivalent to 2-10 cigarette smokers, depending on the compound in question. There is therefore good reason to include waterpipe tobacco smoking in public smoking bans.
