Abstract
In this study, a polyethylene Pasteur pipette-based ultrasound-assisted emulsification microextraction (USAEME) applying low-density organic solvent was successfully developed for the extraction of trace levels of organochlorine pesticides (OCPs) in water samples and followed by gas chromatography-mass spectrometry (GC-MS) analysis. In this approach, a polyethylene Pasteur squeeze-type pipette was employed as a convenient extraction device and ultrasound radiation was applied to accelerate the emulsification of low-density organic solvent in aqueous solutions to enhance the microextraction efficiency of OCPs in water samples. Thirty microliters of extraction solvent (isooctane), of lower density than water, were injected into the aqueous sample solution held in the pipette. The latter was then immersed in an ultrasound water bath to form an emulsion. After 30s extraction, phase separation was achieved by centrifugation. The upper layer (isooctane) was collected and analyzed by GC-MS. No disperser solvent was required in this procedure. Significantly, fast analysis and high extraction efficiency were achieved. Another feature of the procedure was the use of the pipette as the extraction device, which permitted less dense than water organic solvent to be used as extraction solvent. This method broadens the applicability of USAEME to a wider range of solvent. Additionally, carry-over problems were avoided with the use of the disposable pipette. Parameters affecting the efficiency of polyethylene Pasteur pipette-based USAEME, such as the extraction solvent, extraction solvent volume, extraction and centrifugation time, ionic strength and extraction temperature were investigated. Under the optimum conditions, the proposed method provided good enrichment factors (EFs) in the range of 128 and 328, with relative standard deviations (RSDs) ranging from 2.7% to 12.4%. The limits of detection were in the range of 0.8 and 10ng/L depending on the analytes. The linearities were between 0.01 and 50mug/L for hexachlorobenzene, dieldrin, endrin and o,p'-DDD, 0.05-25mug/L for heptachlor, and 0.005-50mug/L for p,p'-DDE. Finally, the polyethylene Pasteur pipette-based USAEME was successfully used for the fast determination of OCPs in river and tap water samples. The proposed method provides a simple, convenient, rapid, sensitive, cost-effective, and environmentally friendly process for the determination of OCPs in water samples.

Abstract
BACKGROUND: Short-segment Barrett's esophagus (SSBE) or long-segment Barrett's esophagus (LSBE) is the consequence of chronic gastroesophageal reflux disease (GERD), which is frequently associated with obesity. Obesity is a significant risk factor for the development of GERD symptoms, erosive esophagitis, Barrett's esophagus, and esophageal adenocarcinoma. Morbidly obese patients who submitted to gastric bypass have an incidence of GERD as high as 50% to 100% and Barrett's esophagus reaches up to 9% of patients. METHODS: In this prospective study, we evaluate the postoperative results after three different procedures--calibrated fundoplication + posterior gastropexy (CFPG), fundoplication + vagotomy + distal gastrectomy + Roux-en-Y gastrojejunostomy (FVDGRYGJ), and laparoscopic resectional Roux-en-Y gastric bypass (LRRYGBP)--among obese patients. RESULTS: In patients with SSBE who submitted to CFPG, the persistence of reflux symptoms and endoscopic erosive esophagitis was observed in 15% and 20.2% of them, respectively. Patients with LSBE were submitted to FVDGRYGJ or LRRYGBP which significantly improved their symptoms and erosive esophagitis. No modifications of LESP were observed in patients who submitted to LRRYGBP before or after the operation. Acid reflux diminished after the three types of surgery were employed. Patients who submitted to LRRYGBP presented a significant reduction of BMI from 41.5 +/- 4.3 to 25.7 +/- 1.3 kg/m(2) after 12 months. CONCLUSIONS: Among patients with LSBE, FVDGRYGJ presents very good results in terms of improving GERD and Barrett's esophagus, but the reduction of weight is limited. LRRYGBP improves GERD disease and Barrett's esophagus with proven reduction in body weight and BMI, thus becoming the procedure of choice for obese patients.

Abstract
BACKGROUND: Based on contradictory findings concerning the use of lasers for enamel etching, the purpose of this study was to investigate the shear bond strength of teeth prepared for bonding with Er-YAG laser etching and compare them with phosphoric acid etching. MATERIALS AND METHODS: In this in vitro study forty - eight premolars, extracted for orthodontic purposes were randomly divided in to three groups. Thirty-two teeth were exposed to laser energy for 25 s: 16 teeth at 100 mj setting and 16 teeth at 150 mj setting. Sixteen teeth were etched with 37% phosphoric acid. The shear bond strength of bonded brackets with the Transbond XT adhesive system was measured with the Zwick testing machine. Descriptive statistics, Kolmogorov-Smirnov test, of homogeneity of variances, one- way analysis of variances and Tukey's test and Kruskal Wallis were used to analyze the data. RESULTS: The mean shear bond strength of the teeth lased with 150 mj was 12.26 +/- 4.76 MPa, which was not significantly different from the group with acid etching (15.26 +/- 4.16 MPa). Irradiation with 100 mj resulted in mean bond strengths of 9.05 +/- 3.16 MPa, which was significantly different from that of acid etching (P

Abstract
BACKGROUND: The aim of the study was to determine the prevalence of shisha smoking and associated factors among medical students in Malaysia. MATERIALS AND METHODS: A cross-sectional study was conducted at the Management and Science University from December 2011 until March 2012. The questionnaire consisted of five sections including socio-demographic, social environment, knowledge about shisha, psychosocial factors, and personal shisha smoking behavior. Obtained data were analyzed using Statistical Package for the Social Sciences (SPSS 13). T-test was used to determine the relationships between shisha smoking and socio-demographic characteristic. RESULTS: A total number of 300 medical students participated in this study. Mean age was 22.5+/-2.5 years. The majority were female, Malay, single, from urban areas (67%, 54%, 97%, 73%; respectively). The prevalence of shisha smoking among medical students was found to be 20%. The study revealed that many students believed that shisha does not contains nicotine, carbon monoxide, does not lead to lung cancer, dental problems and does not lead to cardiovascular diseases (25%, 20.7%, 22.3%, 29%, 26.7%; respectively). Age and sex were found to be significantly associated with smoking shisha status among medical students (p=0.029, p

Abstract
An accurate quantitative determination and confirmative method for bisphenol diglycidyl ether residues, bisphenol A diglycidyl ether (BADGE), bisphenol F diglycidyl ether (BFDGE), bisphenol A (2,3-dihydroxypropyl) glycidyl ether (BADGE H2O), bisphenol A bis (2,3-dihydroxypropyl) ether (BADGE x 2H2O), bisphenol A (3-chloro-2-hydroxy propyl) (2,3-dihydroxypropyl) ether (BADGE x H2O x HCl), bisphenol A (3-chloro-2-hydroxypropyl) glycidyl ether (BADGE x HCl), bisphenol A bis(3-chloro-2-hydroxypropyl) ether (BADGE x 2HCl), bisphenol F bis (2, 3-dihydroxypropyl) ether (BFDGE x 2H2O), bisphenol F bis (3-chloro-2-hydroxypropyl) ether (BFDGE x 2HCl) in canned foodstuffs by high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) has been established. The sample was extracted with tert-butylmethyl ether and the extract was cleaned-up and concentrated on a Waters Oasis HLB column. The target compounds were analyzed by HPLC-MS/MS on a C18 column by the gradient elution with methanol and 5 mmol/L ammonium acetate containing 0.1% formic acid in a multiple reaction monitoring (MRM) scan mode. External matrix standard solutions were used for the quantitative determination and the calibration curves showed good linearity in the concentration range of 10.0 -2 000.0 microg/L for the nine target compounds. The limits of quantification of the nine compounds were 10.0 microg/kg (S/N > or = 10). The average recoveries of the nine compounds ranged from 79.6% to 100.9% at the spiked levels of 10.0, 100.0, 1 000.0 microg/kg with the relative standard deviations (RSDs) of 6.3%-12.1%. The method is sensitive, accurate, and suitable for the rapid determination of bisphenol diglycidyl ether residues in canned foodstuffs.

Abstract
Success in sandwich technique procedures can be achieved through an acceptable bond between the materials. The aim of this study was to compare the effect of 35% phosphoric acid and Er,Cr:YSGG laser on shear bond strength of conventional glass-ionomer cement (GIC) and resin-modified glass-ionomer cement (RMGIC) to composite resin in sandwich technique. Sixty-six specimens were prepared from each type of glass-ionomer cements and divided into three treatment groups as follows: without pretreatment, acid etching by 35% phosphoric acid for 15 s, and 1-W Er,Cr:YSGG laser treatment for 15 s with a 600-mum-diameter tip aligned perpendicular to the target area at a distance of 1 mm from the surface. Energy density of laser irradiation was 17.7 J/cm(2). Two specimens in each group were prepared for evaluation under a scanning electron microscope (SEM) after surface treatment and the remainder underwent bonding procedure with a bonding agent and composite resin. Then the shear bond strength was measured at a crosshead speed of 0.5 mm/min. Two-factor analysis of variance and post-hoc Tukey test showed that the cement type, surface treatment method, and the interaction of these two factors significantly affect the shear bond strength between glass-ionomer cements and composite resin (p

Abstract
A novel chemically bonded graphene oxide/fused-silica fiber was prepared and applied in solid-phase microextraction of six polycyclic aromatic hydrocarbons from water samples coupled with gas chromatography. It exhibited high extraction efficiency and excellent stability. Effects of extraction time, extraction temperature, ionic strength, stirring rate and desorption conditions were investigated and optimized in our work. Detection limits to the six polycyclic aromatic hydrocarbons were less than 0.08 mug/L, and their calibration curves were all linear (R(2)>/=0.9954) in the range from 0.05 to 200 mug/L. Single fiber repeatability and fiber-to-fiber reproducibility were less than 6.13 and 15.87%, respectively. This novel fiber was then utilized to analyze two real water samples from the Yellow River and local waterworks, and the recoveries of samples spiked at 1 and 10 mug/L ranged from 84.48 to 118.24%. Compared with other coating materials, this graphene oxide-coated fiber showed many advantages: wide linear range, low detection limit, and good stability in acid, alkali, organic solutions and at high temperature.

Abstract
BACKGROUND: Nearly all California casinos currently allow smoking, which leads to potentially high patron exposure to secondhand tobacco smoke pollutants. Some argue that smoking restrictions or bans would result in a business drop, assuming > 50% of patrons smoke. Evidence in Nevada and responses from the 2008 California tobacco survey refute this assertion. The present study investigates the proportion of active smokers in southern California tribal casinos, as well as occupancy and PM(2.5) levels in smoking and nonsmoking sections. METHODS: We measured active-smoker and total-patron counts during Friday or Saturday night visits (two per casino) to smoking and nonsmoking gaming areas inside 11 southern California casinos. We counted slot machines and table games in each section, deriving theoretical maximum capacities and occupancy rates. We also measured PM(2.5) concentrations (or used published levels) in both nonsmoking and smoking areas. RESULTS: Excluding one casino visit with extremely high occupancy, we counted 24,970 patrons during 21 casino visits of whom 1,737 were actively smoking, for an overall active- smoker proportion of 7.0% and a small range of ~5% across casino visits (minimum of 5% and maximum of 10%). The differences in mean inter-casino active-smoker proportions were not statistically significant. Derived occupancy rates were 24% to 215% in the main (low-stakes) smoking-allowed slot or table areas. No relationship was found between observed active-smoker proportions and occupancy rate. The derived maximum capacities of nonsmoking areas were 1% to 29% of the overall casino capacity (most under 10%) and their observed occupancies were 0.1 to over 3 times that of the main smoking-allowed casino areas. Seven of twelve visits to nonsmoking areas with no separation had occupancy rates greater than main smoking areas. Unenclosed nonsmoking areas don't substantially protect occupants from PM2.5 exposure. Nonsmoking areas encapsulated inside smoking areas or in a separate, but unenclosed, area had PM(2.5) levels that were 10 to 60 mug/m(3) and 6 to 23 mug/m(3) higher than outdoor levels, respectively, indicating contamination from smoking. CONCLUSIONS: Although fewer than roughly 10% of casino patrons are actively smoking on average, these individuals substantially increase PM(2.5) exposure for all patrons in smoking and unenclosed nonsmoking areas. Nonsmoking areas may be too inconvenient, small, or undesirable to serve a substantial number of nonsmoking patrons. Imposing indoor smoking bans, or contained smoking areas with a maximum capacity of up to 10% of the total patronage, would offer protection from PM2.5 exposures for nonsmoking patrons and reduce employee exposures.

Abstract
A sample preparation method for the determination of hydroxylated polycyclic aromatic hydrocarbons (OH-PAHs) in sediment samples was developed using gas chromatography-mass spectrometry (GC-MS). Dispersive liquid-liquid microextraction (DLLME) with derivatization was performed following the subcritical water extraction (SWE) that provided which was provided by accelerated solvent extraction (ASE). Several important parameters that affected both SWE extraction and DLLME, such as the selection of organic modifier, its volume, extraction temperature, extraction pressure and extraction time were also investigated. High sensitivity of the hydroxylated PAHs derivatives by N-(tert-butyldimethylsilyl)-N-methyl-trifluoroacetamide (MTBSTFA) could be achieved with the limits of detection (LODs) ranging from 0.0139 (2-OH-nap) to 0.2334 mug kg(-1) (3-OH-fluo) and the relative standard deviations (RSDs) between 2.81% (2-OH-phe) and 11.07% (1-OH-pyr). Moreover, the proposed method was compared with SWE coupled with solid phase extraction (SPE), and the results showed that ASE-DLLME was more promising with recoveries ranging from 57.63% to 91.07%. The proposed method was then applied to determine the hydroxylated metabolites of phenanthrene in contaminated sediments produced during the degradation by two PAH-degraders isolated from mangrove sediments.

Abstract
Narghile (water pipe, hookah, shisha, goza, hubble bubble, argeela) is a traditional method of tobacco use. In recent years, its use has increased worldwide, especially among young people. Narghile smoking, compared to cigarette smoking, can result in more smoke exposure and greater levels of carbon monoxide (CO). We present an acutely confused adolescent patient who had CO poisoning after narghile tobacco smoking. She presented with syncope and a carboxyhemoglobin level of 24% and was treated with hyperbaric oxygen. Five additional cases of CO poisoning after narghile smoking were identified during a literature search, with carboxyhemoglobin levels of 20 to 30%. Each patient was treated with oxygen supplementation and did well clinically. In light of the increasing popularity of narghile smoking, young patients presenting with unexplained confusion or nonspecific neurologic symptoms should be asked specifically about this exposure, followed by carboxyhemoglobin measurement.
