Abstract
OBJECTIVE: This study was undertaken to assess the effect of enamel deproteinization with 5.25% sodium hypochlorite (NaOCl) before phosphoric acid (H3PO4) etching on the shear bond strength ofAdperTM Single Bond 2 adhesive and Filtek Z-350 XT composite resin. STUDY DESIGN: Forty human sound permanent molars which were extracted for periodontal reasons were used in the experimental protocol as under: Group-A (20 teeth):-A 5X4 mm window of the enamel surface was etched with 37% H3PO4 gel for 15 seconds, washed with distilled water and air dried. A single coat of Adper Single Bond 2 adhesive was applied and photo polymerized for 20 seconds and Filtek Z-350 XT composite resin block of length 5 mm, width 4 mm and height 5mm respectively was built and photo polymerized in increments for 20 seconds each. Group-B (20 teeth):--Similarly the enamel surface was treated with 5.25% NaOCl for 60 seconds, washed with distilled water and then etched with 37% H3PO4 gel for 15 seconds, washed with distilled water and air dried. A single coat of Adper Single Bond 2 adhesive was applied and photo polymerized for 20 seconds and Filtek Z-350 XT composite resin block of length 5 mm, width 4 mm and height 5 mm respectively was built and photo polymerized in increments for 20 seconds each. The shear bond strength of all the samples were measured (in MPa) on Instron Mechanical Testing Machine. RESULTS: The mean shear bond strength value for Group-A was 13.51 +/- 5.726 MPa and for Group-B being 15.06 +/- 6.220 MPa. No statistically significant difference in the shear bond strengths was observed between the two groups. CONCLUSIONS: No significant effect of sodium hypochlorite enamel deproteinization on the shear bond strength of Adper Single Bond 2 adhesive and Filtek Z-350 XT composite resin before acid etching was observed in this study.

Abstract
INTRODUCTION: An unintended consequence of indoor smoking restrictions is the relocation of smoking to building entrances, where non-smokers may be exposed to secondhand smoke, and smoke from outdoor areas may drift through entrances, exposing people inside. Tobacco smoke has been linked to numerous health effects in non-smokers and there is no safe level of secondhand smoke (SHS) exposure. This paper presents data on levels of tobacco smoke inside and outside entrances to office buildings. METHODS: Real-time air quality monitors were used to simultaneously measure respirable particulate matter (PM(2.5); air pollutant particles with a diameter of 2.5 mug or less) as a marker for tobacco smoke, outside and inside 28 entrances to office buildings in downtown Toronto, Ontario, in May and June 2008. Measurements were taken when smoking was and was not present within 9 m of entrances. Background levels of PM(2.5) were also measured for each session. A mixed model analysis was used to estimate levels of PM(2.5), taking into account repeated measurement errors. RESULTS: Peak levels (10 s averages) of PM(2.5) were as high as 496 mug/m(3) when smoking was present. Mixed model analysis shows that the average outdoor PM(2.5) with smoking was significantly higher than the background level (p/= 5 lit cigarettes was 2.5 times greater than the average background level. CONCLUSIONS: These findings support smoke-free policies at entrances to buildings to protect non-smokers from exposure to tobacco smoke.

Abstract
Bacteriocins produced by Lactobacillus salivarius have been recently recognized as a natural means to control Campylobacter and Salmonella in live poultry. This finding is of relevance since Campylobacter jejuni and Campylobacter coli are the predominant species isolated from poultry that are associated with human campylobacteriosis. In the present work, lactic acid bacteria (LAB) isolated from the cecum of twenty Tunisian chickens were identified and those isolates with antagonism against Campylobacter were further characterized. Following their preliminary confirmation as LAB, 150 strains were identified by combining morphological criteria, biochemical tests, and molecular methods, the latter inluding intergenic 16S- 23S PCR, specific lactobacilli PCR, and a biphasic approach. Most of the LAB isolated belonged to the genus Lactobacillus, among them Lb. sakei (33.3%), Lb. salivarius (19.4%), Lb. reuteri (8.6%), and Lb. curvatus (8.6%). The other LAB strains included those of the genus Weissella (16.7%), Enterococcus faecalis (5.3%), Leuconostoc mesenteroides (2.7%), Lactococcus graviae (2.7%), and Streptococcus sp. (2.7%). The Lactobacilli strains were tested for their antagonism against C. jejuni and C. coli. The activity of three of them, Lb. salivarius SMXD51, Lb. salivarius MMS122, and Lb. salivarius MMS151, against the aforementioned target strains could be ascribed to the production of bacteriocins.

Abstract
INTRODUCTION: Cigarette smoking is the leading preventable cause of premature deaths in the U.S., accounting for approximately 443,000 deaths annually. Although smoking prevalence in recent decades has declined substantially among all racial/ethnic groups, disparities in smoking-related behaviors among racial/ethnic groups continue to exist. Two of the goals of Healthy People 2020 are to reduce smoking prevalence among adults to 12% or less and to increase smoking cessation attempts by adult smokers from 41% to 80%. Our study assesses whether correlates of quit attempts vary by race/ethnicity among adult (>/= 18 years) smokers in the U.S. Understanding racial/ethnic differences in how both internal and external factors affect quit attempts is important for targeting smoking-cessation interventions to decrease tobacco-use disparities. METHODS: We used 2003 Tobacco Use Supplement to the Current Population Survey (CPS) data from 16,213 adults to examine whether the relationship between demographic characteristics, smoking behaviors, smoking policies and having made a quit attempt in the past year varied by race/ethnicity. RESULTS: Hispanics and persons of multiple races were more likely to have made a quit attempt than whites. Overall, younger individuals and those with >high school education, who smoked fewer cigarettes per day and had smoked for fewer years were more likely to have made a quit attempt. Having a smoke-free home, receiving a doctor's advice to quit, smoking menthol cigarettes and having a greater time to when you smoked your first cigarette of the day were also associated with having made a quit attempt. The relationship between these four variables and quit attempts varied by race/ethnicity; most notably receiving a doctor's advice was not related to quit attempts among Asian American/Pacific Islanders and menthol use among whites was associated with a lower prevalence of quit attempts while black menthol users were more likely to have made a quit attempt than white non-menthol users. CONCLUSIONS: Most correlates of quit attempts were similar across all racial/ethnic groups. Therefore population-based comprehensive tobacco control programs that increase quit attempts and successful cessation among all racial/ethnic groups should be continued and expanded. Additional strategies may be needed to encourage quit attempts among less educated, older, and more addicted smokers.

Abstract
OBJECTIVE: To accelerate the conversion of rice straw into feeds in the low-temperature region, a microbial community was constructed by continuous enrichment cultivation. Microbial diversity and dynamics during the fermentation at 10 degrees C was analyzed. METHODS: The community was selected at 5 degrees C under static condition. To analyze the inoculating effects, the community and commercial inoculant ( CI: composed of Lactobacillus plantarum, Enterococcus faecium, L. salivarilus, Pediococcus acidilactici) were respectively inoculated into the rice straw for 30 d fermentation at 10 degrees C. Fermented products were detected by gas chromatography - mass spectrometry (GC-MS). Composition microorganisms of the community were analyzed using cloning library. Microbial dynamics during the fermentation was detected by denatured gradient gel eletrophoresis (DGGE). Quantitative PCR was used for tracking the composition microorganisms of the community during the fermentation. RESULTS: The results from 16S rDNA cloning library showed that the community was mainly composed of Lactobacillus spp. and Leuconostoc spp. At 6d fermentation, the pH and the lactic acid bacterial colony forming units (LAB CFUs) in the fermented rice straw with the community amounted to 4.3 and 2.9 x 10(9) CFU/g fresh matter (FM), respectively. The pH and LAB CFUs with the CI were respectively 5.3 and 2.9 x 10(9) CFU/g FM. At 30 d fermentation, the lactic acid concentrations with the community and the CI were respectively 8.1 g/kg FM and 2.0 g/kg FM. From DGGE patterns, both L. sakei and Leuconostoc inhae of the community were detected at 6d fermentation and existed during the fermentation. For the treatment with the CI, the uncultured bacterium was detected at 6d fermentation besides the composition microorganisms of the CI. At 16d and 30d fermentation, only L. plantarum and E. faecium were detected. Quantitative PCR showed DNA mass of L. sakei amounted to 41.0% at 6d fermentation in the treatment with the community. At 16d, DNA mass of L. sakei was 65%. The highest value (5.5%) of DNA mass of Le inhae appeared at 6d of fermentation. CONCLUSION: The community could effectively colonize into the rice straw fermentation system and accelerate the fermentation process at low temperature. The dominating microorganism of the community was L. sakei at 10 degrees C.

Abstract
In this study, poly(ethylene glycol) (PEG) grafted onto multi-walled carbon nanotubes (PEG-g-MWCNTs) were synthesized by the covalent functionalization of MWCNTs with hydroxyl-terminated PEG chains. For the first time, functionalized product of PEG-g-MWCNTs was used as selective stationary phase to prepare the sol-gel solid-phase microextraction (SPME) fiber in combination with gas chromatography-flame ionization detector (GC-FID) for the determination of ultra-trace levels of benzene, toluene, ethylbenzene and o-xylene (BTEX) in real water samples. The PEG-g-MWCNTs were characterized by Fourier transform infrared spectra and also thermo-gravimetric analysis, which verified that PEG chains were grafted onto the surface of the MWCNTs. The scanning electron micrographs of the fiber surface revealed a highly porous structure which greatly increases the surface area for PEG-g-MWCNTs sol-gel coating. This fiber demonstrated many inherent advantages, the main being the strong anchoring of the coating to the fused silica resulting from chemical bonding with the silanol groups on the fused-silica fiber surface. The new PEG-g-MWCNTs sol-gel fiber is simple to prepare, robust, with high thermal stability and long lifetime, up to 200 extractions. Important parameters influencing the extraction efficiency such as desorption temperature and time, extraction temperature, extraction time, stirring speed and salt effect were investigated and optimized. Under the optimal conditions, the method detection limits (S/N=3) were in the range of 0.6-3 pg mL(-1) and the limits of quantification (S/N=10) between 2 and 10 pg mL(-1). The relative standard deviations (RSDs) for one fiber (repeatability) (n=5) were obtained from 4.40 up to 5.75% and between fibers or batch to batch (n=3) (reproducibility) in the range of 4.31-6.55%. The developed method was successfully applied to real water samples while the relative recovery percentages obtained for the spiked water samples at 20 pg mL(-1) were from 90.21 to 101.90%.

Abstract
In order to study the pollution status and the seasonal and diurnal variations, ambient concentrations of BTEX were analyzed at Beijing from 2008-10 to 2009-10, by using the method of two-step-concentration-gas spectrometry/mass (CCD-GC/MS). The average concentration of BTEX in Beijing was 13.9-44.0 microg x cm(-3). The dominant compound components were toluene, benzene, followed by ethyl benzene, m/p-xylene, o-xylene. Compared with foreign cities and regions, the level of BTEX at Beijing atmosphere was relatively lower. The study found that BTEX in Beijing mainly came from vehicle emissions, coal and solvent evaporation were also important sources of BTEX. No significantly obvious seasonal variation was observed, with the highest concentrations observed in spring and summer and the lowest concentrations generally found in autumn. Seasonal variations of emission sources were the main reason for seasonal changes of BTEX. However, the impact of weather factors on the BTEX can not be ignored, such as temperature and strong winds. Significant diurnal variations in BTEX were observed. The BTEX concentrations displayed a bimodal pattern, with peak between 08:00 and 10:00. and between 16:00 and 08:00. The minimum concentration generally appeared around 14:00.

Abstract
BACKGROUND: The effects of workplace second-hand smoke (SHS) on lung function remain uncertain because of a lack of objective measures for SHS exposures. OBJECTIVE: To determine whether an exposure-response association exists between lung function and two different markers of SHS based on indoor fine particulate (PM(2.5)) and urinary cotinine levels in non-smoking catering workers. DESIGN: A cross-sectional study during a 1.5-year exemption of licensed catering premises from smoke-free legislation. Participants 186 non-smoking catering workers aged 18-65 years in Hong Kong were recruited. A declared non-smoking status was accepted in workers with exhaled breath carbon monoxide levels 175 mug/m(3)) with FEV(1) -0.072 (95% CI -0.123 to -0.021), -0.078 (95% CI -0.132 to -0.024), -0.101 (95% CI -0.187 to -0.014); FEF(25-75) -0.368 (95% CI -0.660 to -0.077), -0.489 (95% CI -0.799 to -0.179), -0.597 (95% CI -0.943 to -0.251); and FEV(1)/FVC (%) -2.9 (95% CI -4.8 to -1.0), -3.2 (95% CI -5.1 to -1.4) and -4.4 (95% CI -7.4 to -1.3), respectively. Urinary cotinine was associated positively with indoor PM(2.5) but negatively with lung function. Consistently lower values for lung function per unit increase of indoor PM(2.5) were found. CONCLUSION: Lung function is inversely associated with workplace SHS. Workplace exemptions and delays in implementing smoke-free policies and current moves to relax legislation are a major threat to the health of workers.

Abstract
We have examined the effect of continuous perfusion with antifungals on Candida albicans biofilms under conditions of flow, closely mimicking physiological conditions encountered within patients. Biofilms displayed high levels of resistance to fluconazole, and this antifungal exerted minor effects on dispersion levels. Amphotericin B proved effective in reducing viability of cells within the biofilms and dispersion, but only at high concentrations. Under flow conditions, caspofungin exhibited potent activity against biofilms and drastically reduced biofilm dispersion.

Abstract
BACKGROUND: Second-hand smoke contains several toxic chemicals that are known to pollute the air and harm people's health. In India, smoking in public places has been prohibited since October 2008 as a way to reduce second-hand smoke (SHS) exposure. The purpose of the present study was to assess the implementation of smoke-free policies and its impact on indoor air quality by measuring the PM(2.5) levels in bars and restaurants, restaurants, country liquor bars, hookah restaurants and pubs in Mumbai. MATERIALS AND METHODS: Air quality measurements at 50 venues were conducted by using a "SIDEPAK() AM510 Personal Aerosol Monitor" during April to May 2009. Average concentration of PM(2.5) (mug/m(3)) particles was calculated separately for each venue. RESULTS: Smoking was observed in 36% of the surveyed venues during an hour of data collection. The PM(2.5) levels ranged from 16.97 to 1101.76 mug/m(3). The average level of PM(2.5) among non-smoking venues was 97.19 mug/m(3) and among smoking venues was 363.04 mug/m(3). CONCLUSION: Considerable scope for improvement in implementation of smoke-free policies exists. The PM(2.5) levels were exceedingly high in venues where smoking was observed.
