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
Wastewater treatment plants (WWTP) receiving effluents from food-producing animals and humans may contribute to the spread of ESBL-carrying plasmids. This study was designed to investigate extended-spectrum cephalosporin resistant E. coli strains, CTX-M distributions and the genetic lineage of blaCTX-M -carrying plasmids from urban and slaughterhouse wastewaters. The level of extended-spectrum cephalosporin-resistant E. coli in slaughterhouse wastewater entering the WWTP was negligible compared to that of urban wastewater. The blaCTX-M-1 gene was predominant in slaughterhouse wastewater whereas diverse blaCTX-M genes were encountered in urban wastewater and WWTP outlet. Characterization of the main CTX-M-producing E. coli isolates by antibiotic resistance phenotyping, genotyping and typing of plasmids carrying blaCTX-M genes revealed that blaCTX-M-1 and blaCTX-M-15 genes were harbored by the predominant blaCTX-M-1 IncI1/ST3 and blaCTX-M-15 F31:A4:B1 plasmids, which were recovered from unrelated E. coli genotypes in both slaughterhouse and urban wastewaters. This study highlighted the spread of predominant blaCTX-M-1 and blaCTX-M-15 plasmid lineages in diverse E. coli genotypes from humans and food-producing animals, their mixing in WWTP and final release into the aquatic environment. This could have a serious negative impact on public health and requires further evaluation. This article is protected by copyright. All rights reserved.

Abstract
The aim of the present study was to replicate the distinction between errors, lapses and violations, and to identify aggressive violations from normal or highway code violations. Furthermore, the relationship of these behaviours with road traffic accidents was examined. A total number of 1126 Finnish drivers completed a questionnaire containing the Driver Behaviour Questionnaire (DBQ) with extended violations scale, and questions regarding background information, such as age, gender and mileage. Also, questions about previous accidents and fines were asked. Factor analysis showed that a four-factor structure seemed more appropriate than the earlier established three-factor structure. The four factors were errors, lapses, speeding violations and interpersonal violations. The two types of violations result from different motives, and seem to be associated with different kinds of affect. Both interpersonal and speeding violations were reported most by young males, which was consistent with earlier findings. Logistic regression analyses indicated that errors predicted active accident involvement after partialling out the effects of demographic variables, whereas interpersonal violations were positively related to involvement in passive accidents. This was presumably due to different reporting tendencies of respondents. Speeding tickets were predicted by speeding and interpersonal violations and lapses and penalties for speeding by both kinds of violations and errors. Penalties for speeding, parking and other offences were predicted by interpersonal violations. The implications of these results are discussed.

Abstract
INTRODUCTION: Research demonstrates that lesbians, gays, and bisexuals (i.e., LGBs or sexual minorities) smoke more than their heterosexual peers, but relatively less is known about the heterogeneity within LGB populations, namely racial/ethnic differences. Moreover, smoking research on sexual minorities has focused mainly on cigarette smoking, with little attention to other forms of smoking, such as hookahs/water pipes. METHODS: Using a large national sample of college students, we examined differences by race and sexual orientation in prevalence of smoking cigarettes, cigars/cigarillos/clove cigarettes, and hookahs. RESULTS: All LGB racial groups had higher cigarette smoking prevalence than their heterosexual racial group counterparts. Significantly more White and Hispanic LGBs smoked hookahs when compared, respectively, with White and Hispanic heterosexuals. CONCLUSIONS: Given the higher prevalence of multiple forms of smoking among sexual minorities, the heterogeneity within sexual minority populations and the nuances of multiple identities (i.e., racial, ethnic, and sexual minority), targeted-if not tailored-prevention and cessation efforts are needed to address smoking disparities in these diverse communities. Prevention, intervention, and epidemiological research on smoking behaviors among college attending young adults should take into account other forms of smoking, such as hookah use.

Abstract
INTRODUCTION: Tobacco use is the leading cause of morbidity and mortality in the United States. Hookah use is a growing tobacco trend among young adults; yet little is known about how young adult college student hookah smokers differ from nonsmokers or cigarette smokers. METHODS: Results from 18- to 24-year-old participants in the Fall 2008-Spring 2009 National College Health Assessment II (N = 82,155) were used in multinomial logistic regression models to compare nonsmokers, cigarette-only smokers, hookah-only smokers, and dual (cigarette and hookah) users. RESULTS: Ten percent of the sample reported hookah use in the last 30 days. Compared with nonsmokers, cigarette, hookah, and dual users were more likely to be younger, male, White, and use other substances (including alcohol). Compared with nonsmokers, hookah and dual users were more likely to be members of fraternities/sororities (odds ratio [OR] = 1.17 and 1.14, respectively), live in the West (OR = 1.49 and 1.31, respectively), and attend larger institutions. Compared with cigarette-only smokers, hookah and dual users were more likely to be younger, male, live on campus, live in the West, attend large institutions, and were less likely to attend public institutions. Compared with cigarette-only smokers, hookah-only users were more likely to be non-White and less likely to use marijuana or other drugs. CONCLUSIONS: Hookah-only and dual users are demographically different than cigarette-only or nonsmoking college students. Interventions for tobacco use on college campuses should address the demographic differences among tobacco users (including polysubstance use) and attempt to recruit students as entering freshman to provide education and prevent hookah use uptake.

Abstract
The feasibility of using reject heat from electrical power plants for undersoil heating has been analytically considered. Since soil is a poor thermal conductor, a suitable arrangement of undersoil pipes is required in order to achieve a somewhat uniformly elevated soil temperature. Two dimensional steady temperature profiles in soil resulting from a warm water pipe having a wall temperature of 37.8C were computed for several pipe configurations and surface heat transfer coefficients of 1.36 and 136 cal.sec-1.m-2C-1. Values of heat transfer on the order of 5 cal.sec-1.sec-1.m-1 can be obtained. Calculations indicate that in order to apply this technique for the utilization of significant portions of reject heat, the system must be viewed in terms of an agricultural power plant complex encompassing large quantities of land.

Abstract
BACKGROUND: Dengue is a major mosquito-borne disease currently with no effective antiviral or vaccine available. Effort to find antivirals for it has focused on bioflavonoids, a plant-derived polyphenolic compounds with many potential health benefits. In the present study, antiviral activity of four types of bioflavonoid against dengue virus type -2 (DENV-2) in Vero cell was evaluated. Anti-dengue activity of these compounds was determined at different stages of DENV-2 infection and replication cycle. DENV replication was measured by Foci Forming Unit Reduction Assay (FFURA) and quantitative RT-PCR. Selectivity Index value (SI) was determined as the ratio of cytotoxic concentration 50 (CC50) to inhibitory concentration 50 (IC50) for each compound. RESULTS: The half maximal inhibitory concentration (IC50) of quercetin against dengue virus was 35.7 mug mL-1 when it was used after virus adsorption to the cells. The IC50 decreased to 28.9 mug mL-1 when the cells were treated continuously for 5 h before virus infection and up to 4 days post-infection. The SI values for quercetin were 7.07 and 8.74 mug mL-1, respectively, the highest compared to all bioflavonoids studied. Naringin only exhibited anti-adsorption effects against DENV-2 with IC50 = 168.2 mug mL-1 and its related SI was 1.3. Daidzein showed a weak anti-dengue activity with IC50 = 142.6 mug mL-1 when the DENV-2 infected cells were treated after virus adsorption. The SI value for this compound was 1.03. Hesperetin did not exhibit any antiviral activity against DENV-2. The findings obtained from Foci Forming Unit Reduction Assay (FFURA) were corroborated by findings of the qRT-PCR assays. Quercetin and daidzein (50 mug mL-1) reduced DENV-2 RNA levels by 67% and 25%, respectively. There was no significant inhibition of DENV-2 RNA levels with naringin and hesperetin. CONCLUSION: Results from the study suggest that only quercetin demonstrated significant anti-DENV-2 inhibitory activities. Other bioflavonoids, including daidzein, naringin and hesperetin showed minimal to no significant inhibition of DENV-2 virus replication. These findings, together with those previously reported suggest that select group of bioflavonoids including quercetin and fisetin, exhibited significant inhibitory activities against dengue virus. This group of flavonoids, flavonol, could be investigated further to discover the common mechanisms of inhibition of dengue virus replication.

Abstract
Neuroendocrine tumors (NET) are a diverse group of tumors that derive from epithelial cells with neuroendocrine differentiation. Gastroenteropancreatic NETs are a subset of NET that arise from the gastrointestinal tract. The natural history and prognosis varies widely between different gastroenteropancreatic NETs, highlighting the importance of identifying accurate prognostic and predictive biomarkers. At the 2013 ASCO Gastrointestinal Cancers Symposium, De Braud et al. (Abstract #186) and Bellister et al. (Abstract #163) present data on two new possible biomarkers.

Abstract
Excavation at the Ecuadorian highland site of La Florida in suburban Quito revealed six deep shaft tombs yielding high-status individuals (n = 9) as well as apparent sacrifices and other low-status individuals (n = 23). Determination of sex and age at death of the recovered skeletal remains resulted in a sample of 32 individuals aged from approximately 7 to 50 years of age. The sample of 18 individuals over the age of 18 years included 14 females and 4 males. Temporally, the remains are assigned to the Chaupicruz Phase (circa 100 to 450 AD) of the Regional Developmental Period. In this study, we analyze stable isotopes of carbon and nitrogen from human bone in order to compare the diets of the high- and low-status individuals. Stable carbon isotope analyses were carried out on preserved protein and biological apatite (bioapatite), and stable nitrogen isotope analyses were carried out on preserved protein. There is a statistically significant difference in δ13C between the two groups for both protein and mineral sources of carbon with evidence for the greater consumption of maize in the high-status group. There is no significant difference in δ15N between the two groups, nor is there a significant difference in the spacing between protein and mineral δ13C values between the two groups. Ethnohistorical evidence for the 16th century AD provides the expectation that the only dietary difference was the higher consumption of animal protein by the elite. There is no evidence for this based on the bone chemistry data from La Florida. Instead, the isotope data, along with the archaeological evidence, indicate that the major dietary difference during the Chaupicruz Phase was the greater intake of maize by the elite, probably in the form of beer (chicha).

Abstract
This article reviews the research literature since 1980 on alcohol and other (illicit) drug use among college and university students. The discussion begins with a summary of survey findings on the nature and extent of alcohol and drug use, including prevalence and patterns of use and associated problems. This summary is followed by a discussion of the correlates of substance use and problems, including demographic characteristics, personality factors, year in college and grade point average, college residence, motivation, and attitudes. The most popular substance used by college students is alcohol, used by about 90% of students at least once a year. Heavy alcohol use is also prevalent, and is associated with serious, acute problems. Although alcohol use has decreased somewhat in recent years, much larger declines in use have been recorded for illicit drugs. The major proportion of research on substance use in this population has been devoted to alcohol; more information is needed on the prevalence, patterns, and correlates of illicit drug use. Suggestions for coping with problems of campus alcohol use/abuse are offered.
