However, little is known about their use among adolescents. This article reports on data collected from a New Zealand national youth tobacco use survey in 2012 and 2014. METHODS: The Youth Insights Survey is a biennial self-complete survey of Year 10 students (predominately aged 14-15 years), with a sample size of 3,127 in 2012 and 2,919 in 2014. Ever-use of e-cigarettes was self-reported by participants in both years, and in 2014, e-cigarette ever-users also reported their reasons for first trying e-cigarettes. RESULTS: The rate of e-cigarette ever-use tripled from 7.0% in 2012 to 20.0% in 2014. After adjusting for sociodemographic variables, smoking status (including susceptibility), and other factors associated with tobacco smoking uptake, e-cigarette ever-use was associated with gender, smoking status, close friends' smoking behavior, and risky substance use. Among smokers, desire for a cigarette, quit intention, or past-year quit attempts did not predict e-cigarette ever-use. Irrespective of smoking status, curiosity was the most commonly cited reason for trying e-cigarettes. CONCLUSIONS: In 2014, one in five 14- to 15-year-olds had used e-cigarettes. Our data suggest that for adolescent smokers, cessation was not the main reason for trying e-cigarettes. Instead, most adolescents (smokers and nonsmokers) tried e-cigarettes out of curiosity. Our findings signal a need to continue monitoring the uptake of e-cigarettes among adolescents, including both experimental and long-term use. Controlling access and exposure to e-cigarettes among this young age group is also required. Descriptors Links Book Title Database Publisher Society for Adolescent Health and Medicine.

Total phenol and flavonoid contents, reducing power, and DPPH radical scavenging activity were the optical techniques implemented and included in the referred profile. Flavor extracts were analyzed by HS-SPME/GC-MS to obtain the qualitative and quantitative profiles of the volatile fraction of essential oils. Results pointed out a higher reducing power (0.14-11.8 mg of gallic acid/L) and radical scavenging activity (0.29-211.5 mg Trolox/L) of flavored waters compared with the corresponding natural ones, an interesting fact concerning human health. Bioactive compounds, such as polyphenols, were present in all samples (0.5-359 mg of gallic acid/L), whereas flavonoids were not present either in flavored waters or in flavors. The major components of flavor extracts were monoterpenes, such as citral, alpha-limonene, carveol, and alpha-terpineol.

We aimed to characterize piggeries (pigs, piggery environments) as reservoirs of TEM-52- and CTX-M-encoding plasmids and clones. METHODS: Forty-three samples from five Portuguese intensive production farms were studied (2006-07). Twenty-two ESBL-producing (13 TEM-52, 6 CTX-M-32, 3 CTX-M-1) Escherichia coli isolates from healthy pigs, feed and liquid manure were further characterized. Standard methods were used for clonal (PFGE, MLST) and plasmid (S1-PFGE, replicon typing, pMLST, RFLP) analysis. PCR and sequencing were used for analysis of blaCTX-M genetic context and plasmid-mediated quinolone resistance genes. RESULTS: TEM-52 (n = 13/22; 59%), CTX-M-32 (n = 6/22; 27%) and CTX-M-1 (n = 3/22; 14%) were identified in feed (36%), swine faeces (36%), swine hide (9%) and liquid manure (18%) at different farms. Diverse phylogenetic groups and clones were identified among TEM-52 (7 A, 3 B1, 2 B2, 1 D; 8 clones)-producing, CTX-M-1 (1 A, 1 B1, 1 D; 3 clones)-producing and CTX-M-32 (4 A, 2 B1; 4 clones)-producing isolates. However, the ST10 clonal complex was frequent among TEM-52 (n = 6) and CTX-M-32 (n = 3) producers. blaTEM-52 and blaCTX-M-1/-32 genes were identified within epidemic IncI1/ST3 and IncN/ST1 plasmid variants, respectively. CONCLUSIONS: We report for the first time a piggery reservoir for blaTEM-52. The spread of blaTEM-52 and blaCTX-M-1/-32 within and/or between different piggeries was mostly associated with epidemic plasmids and clones previously identified in humans and other animal hosts in different EU countries, highlighting possible distribution along the food chain.

METHOD AND MATERIALS: Occlusal enamel of 146 molars was removed, and exposed surfaces were ground with a diamond bur to produce bur-cut dentin surfaces. Of those teeth, 120 were assigned to 3 groups of 40 samples in which dentin was conditioned with Er,Cr:YSGG laser, Nd:YAG laser, and 37% orthophosphoric acid (control). Each group was further divided into 2 subgroups, acetone- and ethanol-containing bonding agents, and 4-mm-long x 4-mm-wide composite rods were bonded to all specimens using a Plexiglas mold. Tensile bond strength testing of 120 samples was performed at a crosshead speed of 0.5 mm/min using a 50-kgf load cell. The remaining 26 samples were examined under SEM to evaluate the adaptation/penetration of the bonding materials and the alterations in mineral content. Data were analyzed using 1-way ANOVA and Kruskal-Wallis tests; P < .05 was considered statistically significant. RESULTS: The difference between the mean tensile bond strength values obtained with bonding agents was statistically significant in the control group. The bond strength values of the acetone-containing agent in this group were found to be higher than the ethanol-containing agent (P < .001). When compared with Nd:YAG laser, bond strength values obtained with Er,Cr:YSGG laser were higher (P < .001). The bond strength values obtained in the acid-etched group were highest for both bonding agents and demonstrated statistical significance (P < .001). CONCLUSION: Although in this study laser etching is more influential than the solvent type on bond strengths of dentin bonding agents, it cannot be considered as an alternative to conventional acid etching.

Pub Date Free Form 1993/ Volume 8 Issue 3 Start Page 299 Other Pages 311 Notes Place of Publication ISSN/ISBN 1053-4725 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Current measures of microbe-mediated biogeochemical processes in sediments were examined for their potential use as indicators of heavy metal ecotoxicity in both river sediments and bacterial cultures. Assays were carried out with HgCl2, CuSO4, and 3CdSO4.8H2O added to sediment samples and bacterial cell suspensions at concentra,ions ranging from 0.1 to 10 mM and 0.1 Î¼M to 1 mM, respectively. Chemoautotrophic CO2, fixation by Elbe River sediment microbiota was most sensitive to Hg2+ and Cd2+, but not to Cu2+. Among the estimates of heterotrophic productivity, incorporation of leucine into cellular protein showed clearer dose responses than incorporation of thymidine into bacterial DNA. Thymidine incorporation was highly resistant to and even stimulated by metal ions, particularly in starved and anaerobic cultures of a test strain of Vibrio arguillarum. Similar metal ion induced 'overshoot' responses beyond the levels of untreated controls were noted for mineralization of 14C-glucose by V. anguillarum and, in the case of Cd2+, also in sediment. As a less complex measure of microbial respiratory activity, succinate dehydrogenase (SDH) showed normal dose responses without stimulatory effects, as long as acterial cell homogenates were assayed. Despite this result, it is concluded that levels of SDH in natural sediment microbiota are inevitably affected by metal-induced processes of selection and enzyme synthesis, and would thus fail to provide an appropriate measure of metal ecotoxicity. The final conclusion is that current parameters of microbial production and activity often reveal dose responses that do not fulfill basic requirements of ecotoxicity testing in metal-polluted sediments.

Monitoring the use of WTS in Turkey in relation to the tobacco control policy context is important to ensure that WTS does not become a major public health issue in Turkey. The Global Adult Tobacco Survey (GATS) was conducted in Turkey in 2008 and was repeated in 2012. GATS provided prevalence estimates on current WTS and change over time. Other indicators of WTS were also obtained, such as age of initiation and location of use. Among persons aged 15 and older in Turkey, the current prevalence of WTS decreased from 2.3% in 2008 to 0.8% in 2012, representing a 65% relative decline. Among males, WTS decreased from 4.0% to 1.1% (72% relative decline). While the overall smoking prevalence decreased among females, there was no change in the rate of WTS (0.7% in 2008 vs. 0.5% in 2012), though the WTS prevalence rate was already low in 2008. Comprehensive tobacco control efforts have been successful in reducing the overall smoking prevalence in Turkey, which includes the reduction of cigarette smoking and WTS. However, it is important to continue monitoring the use of waterpipes in Turkey and targeting tobacco control efforts to certain groups that may be vulnerable to future WTS marketing (e.g., youth, women).

DESIGN: A single-arm clinical trial. Participants stayed in a supportive, smoke-free environment for 4 days during which they attended educational sessions on nutrition, exercise, and psychology. Nicotine withdrawal was treated with nicotine inhalers and patches. After discharge, participants attended monthly outpatient group sessions for 6 months. SETTING: The Durham, NC Veterans Affairs Medical Center residential unit. PARTICIPANTS: Twenty-three medical outpatient smokers. MEASUREMENTS: Seven-day point prevalence smoking abstinence was determined by self-report of zero cigarettes smoked and verified by exhaled carbon monoxide <8 parts per million. MAIN RESULTS: Participants' mean age was 57.4 years; 100% were male; 61% were Caucasian; and 39% were African American. The mean score on the Fagerstrom Test for Nicotine Dependence was 7.1 (SD 2.3). Daily nicotine doses ranged from the nicotine inhaler alone to 56 mg of transdermal nicotine plus nicotine inhaler. Verified smoking abstinence on discharge (after 4 days) was 21/23 or 91.3% (95% confidence interval [95% CI], 73 to 100). At 6 months, the 7-day point abstinence rate was 6/23 or 26.1% (95% CI, 15 to 36). CONCLUSIONS: This pilot residential smoking treatment program was designed to assist smokers who relapsed after outpatient treatment. Four days of residential smoking therapy successfully relieved smoking withdrawal. At 6 months after discharge, participants maintained an abstinence rate comparable to other medical therapies for smoking.

Acid etching is the most commonly used method. Recently, hard tissue lasers have been used for this purpose. AIM: The aim of the present study was to evaluate and compare the etching pattern of Er,Cr:YSGG and conventional etching on extracted human enamel and dentin specimens. MATERIALS AND METHODS: Total 40 extracted non-diseased teeth were selected, 20 anterior and 20 posterior teeth each for enamel and dentin specimens respectively. The sectioned samples were polished by 400 grit Silicon Carbide (SiC) paper to a thickness of 1.0 +/- 0.5 mm. The enamel and dentin specimens were grouped as: GrE1 & GrD1 as control specimens, GrE2 & GrD2 were acid etched and GrE3 & GrD3 were lased. Acid etching was done using Conditioner 36 (37 % phosphoric acid) according to manufacturer instructions. Laser etching was done using Er,Cr:YSGG (Erbium, Chromium : Ytrium Scandium Gallium Garnet) at power settings of 3W, air 70% and water 20%. After surface treatment with assigned agents the specimens were analyzed under ESEM (Environmental Scanning Electron Microscope) at X1000 and X5000 magnification. RESULTS: Chi Square and Student "t" statistical analysis was used to compare smear layer removal and etching patterns between GrE2-GrE3. GrD2 and GrD3 were compared for smear layer removal and diameter of dentinal tubule opening using the same statistical analysis. Chi-square test for removal of smear layer in any of the treated surfaces i.e., GrE2-E3 and GrD2-D3 did not differ significantly (p>0.05). While GrE2 showed predominantly type I etching pattern (Chi-square=2.78, 0.050.10) and GrE3 showed type III etching (Chi-square=4.50, p Descriptors Links Book Title Database Publisher Data Source Authors Issar,R., Mazumdar,D., Ranjan,S., Krishna,N.K., Kole,R., Singh,P., Lakiang,D., Jayam,C.

This reactor is chosen as a prototype to demonstrate and prove the feasibility of (17)N detection as a new redundant channel for reactor power measurement. In TRR, similar to other pool type reactors, neutron detectors are immersed in the pool around the core as the main power measuring devices. In the present article, a different approach, using out of water neutron detector, is employed to measure reactor power. This new method is based on (17)O (n,p) (17)N reaction taking place inside the core and subsequent measurement of delayed neutrons emitted due to (17)N disintegration. Count and measurement of neutrons around outlet water pipe provides a reliable redundant safety channel to measure reactor power. Results compared with other established channels indicate a good agreement and shows a linear interdependency with true thermal power. Safety of reactor operation is improved with installation & use of this new power measuring channel. The new approach may equally serve well as a redundant channel in all other types of reactors having coolant comprised of oxygen in its molecular constituents. Contrary to existing channels, this one is totally out of water and thus is an advantage over current instrumentations. It is proposed to employ the same idea on other reactors (nuclear power plants too) to improve safety criteria.
