Abstract
Homology of ars (arsenic-resistance system) genes was examined among the indigenous bacteria isolated from the soils and sediments of two abandoned Au mines, which are highly contaminated with arsenic. The DNA and amino acid sequence homology of the ars determinants were investigated using an ars genotype. The isolated strains showed As(III)-oxidation ability contained arsAB genes encoding the efflux pump as well as arsR and arsD regulator genes. The arsR and arsD leader gene are required for an arsenic resistance system when the high-homology genes (arsR; pI258 52.09% and arsD; Shewanell sp. 42.33%) are controlled by the ars inducer-independent regulatory amino acid sequence. These leader gene were observed under weak acidic conditions in the Myoung-bong (pH; 5.0 to 6.0) and Duck-um (pH; 4.0 to 7.0) mines. In addition, the strains with the ability of As(V)-reduction involved the arsC gene homologues, as in the strain OW-16 (Pseudomonas putida). The arsenic-resistance genes in the isolated indigenous bacteria showed varying degrees of amino acid similarity to the homologous genes found in the database (GenBank) such as P. putida KT2440: 39-53% for arsR, 22-42% for arsD, 16-84% for arsA, 26-45% for arsB, 17-44% for arsAB, 37-41% for arsC, and 14-47% for arsH. These findings suggested that the function of the various ars gene in indigenous bacteria existing in weakly oxidative conditions may be the key factor for redox mechanisms and biogeochemical systems in arsenic contaminated soils. © KSBB.

Abstract
Our objective was to evaluate piperidine alkaloids as potential resistance factors in Sitka spruce, Picea sitchensis (Bong.) Carr, at risk to attack by white pine weevils, Pissodes strobi (Peck). We sampled 72 seedlings in each of two replicated field trials in the Oregon Coast Range. The seedlings were grown from open-pollinated seeds of putatively "resistant" or "susceptible" off-site parental sources. Alkaloid concentrations in bark and foliage were measured in previously unattacked trees at the time of weevil host selection. Leader mortality was evaluated in the fall to gauge actual resistance in the sample trees. Five families had 50% topkill. Alkaloid concentrations differed significantly among families, but the major alkaloids did not appear to be functionally linked with topkill or useful indicators of resistance. However, our study design did not address all potential resistance mechanisms. Therefore, before concluding that Sitka spruce alkaloids have no influence on white pine weevils, complementary laboratory and field experiments are needed.

Abstract
BACKGROUND: In recent years waterpipe smoking has become a popular practice amongst young adults in eastern Mediterranean countries, including Iran. The aim of this study was to assess waterpipe smoking perceptions and practices among first-year health sciences university students in Iran and to identify factors associated with the initiation and maintenance of waterpipe use in this population. RESULTS: Out of 371 first-year health sciences students surveyed, 358 eight students completed a self-administered questionnaire in the classrooms describing their use and perceptions towards waterpipe smoking. Two hundred and ninety six responders met study inclusion criteria. Waterpipe smoking was common among first-year health sciences university students, with 51% of students indicating they were current waterpipe smokers. Women were smoking waterpipes almost as frequently as men (48% versus 52%, respectively). The majority of waterpipe smokers (75.5%) indicated that the fun and social aspect of waterpipe use was the main motivating factor for them to continue smoking. Of waterpipe smokers, 55.3% were occasional smokers, using waterpipes once a month or less, while 44.7% were frequent smokers, using waterpipes more than once a month. A large number of frequent waterpipe smokers perceived that waterpipe smoking was a healthier way to use tobacco (40.6%) while only 20.6% thought it was addictive. Compared to occasional smokers, significantly more frequent smokers reported waterpipe smoking was relaxing (62.5% vs. 26.2%, p = 0.002), energizing (48.5% vs. 11.4%, p = 0.001), a part of their culture (58.8% vs. 34.1%, p = 0.04), and the healthiest way to use tobacco (40.6% vs. 11.1%, p = 0.005). CONCLUSIONS: Social and recreational use of waterpipes is widespread among first-year health sciences university students in Iran. Women and men were almost equally likely to be current waterpipe users. Public health initiatives to combat the increasing use of waterpipes among university students in Iran must consider the equal gender distribution and its perception by many waterpipe smokers as being a healthier and non-addictive way to use tobacco.

Abstract
BACKGROUND: Somalis compose the largest African refugee group living in the U.S., with more than 10,330 primary arrivals in fiscal year 2006 alone. Half of all Somalis in the U.S. live in Minnesota. Although tobacco use is a considerable problem among Somalis, especially among men, little research has examined factors affecting tobacco use and cessation. METHODS: A sequential exploratory design informed the overall study methodology. Key informant interviews (n=20) and focus group discussions (13 groups; n=91) were conducted with Somali adults and youth in the fall of 2006 and the summer of 2007, respectively. Participants were asked about tobacco-use prevalence, prevention, and cessation, and the marketing of tobacco. RESULTS: Perceived prevalence of tobacco use by Somalis is high at 50%. The main reason for initiating tobacco use was the influence of friends or peer pressure and included other social factors. Prevention and cessation messages suggested by participants include medical advice, education on the negative health effects of tobacco use, religion, and the support of family and friends. Barriers to cessation include lack of insurance coverage, lack of knowledge on where to find assistance, and lack of cessation support groups. Severe social stigma for Somali female smokers poses specific challenges to prevention and intervention efforts. Water-pipe smoking is perceived to be prevalent, particularly among female youth. CONCLUSIONS: Somalis view tobacco use as an important issue in their community. Religious and social support and demographically targeted approaches should be key factors in creating effective prevention and cessation programs and must address water-pipe smoking.

Abstract
Unreliable and data-poor marine fishery landings can lead to a lack of regulatory action in fisheries management. Here we use official Chilean landing reports and non-conventional indicators, such as fishers' perceptions and spearfishing competition results, to provide evidence of reef fishes depletions caused by unregulated spearfishing. Results show that the three largest and most emblematic reef fishes targeted mainly by spearfishers (> 98% of landings) Graus nigra (vieja negra), Semicossyphus darwini (sheephead or pejeperro), and Medialuna ancietae (acha)] show signs of depletion in terms of abundance and size and that overall the catches of reef fishes have shifted from large carnivore species toward smaller-sized omnivore and herbivore species. Information from two snorkeling speargun world championships (1971 and 2004, Iquique, Chile) and from fishers' perceptions shows the mean size of reef fish to be declining. Although the ecological consequences of reef fish depletion are not fully understood in Chile, evidence of spearfishing depleting temperate reef fishes must be explicitly included in policy debates. This would involve bans or strong restrictions on the use of SCUBA and hookah diving gear for spearfishing, and minimum size limits. It may also involve academic and policy discussions regarding conservation and fisheries management synergies within networks of no-take and territorial user-rights fisheries areas, as a strategy for the sustainable management of temperate and tropical reef fisheries.

Abstract
OBJECTIVE: To investigate a case of nosocomial legionellosis, identify pathways of transmission, and effect control of the environmental source. DESIGN: Case investigation and environmental culture surveillance. SETTING: A 720-bed university teaching hospital. CASE PATIENT: A ventilator-dependent 66-year-old male developed nosocomial pneumonia due to Legionella pneumophila serogroup 6 after 3 months in an intensive-care unit (ICU). The patient had no intake of potable water except for ice chips from an ice machine in the ICU. RESULTS: Cultures revealed L pneumophila serogroup 6 in the ice (4.3 colony-forming units/mL) and ice machine cold water (too numerous to count). Cultures from adjacent hot and cold taps, plus taps located near the patient, all were negative; ice machines and cold water on seven other patient units also were negative. Only sterile water had been used for tube feedings, mouth care, suctioning, and ventilator humidification. Hospital hot water previously had been colonized with L pneumophila serogroup 6, but all surveillance water cultures had been negative since chlorination of the hot-water system began the previous year; cold-water cultures had never before grown Legionella. The ice machine was disinfected with a 2-hour flush of 2.625% sodium hypochlorite. The supply line to the ice machine was replaced, and the cold-water pipe from the floor below was treated with 83 ppm sodium hypochlorite for 48 hours. All follow-up surveillance cultures of the ice machine remained negative through mid-1996. No additional cases of nosocomial legionellosis occurred. CONCLUSIONS: Ice machines may be reservoirs of L pneumophila in hospitals. Both ice and water dispensed from these machines may be contaminated, and nosocomial transmission may occur. Successful long-term decontamination and control can be accomplished with shock chlorination.

Abstract
OBJECTIVE: This study examined the prevalence and predictors of argileh (hookah pipe) use among a sample of nonselected college students. METHOD: Participants were 602 students (24% male; 43% white; mean age=22.06) at a large, ethnically diverse, urban university. All participants completed an online survey designed to assess various types of substance use. RESULTS: More than 15% of the sample reported having used argileh at least once in their lifetime, exceeding the percentage of students who had tried stimulants, barbiturates, cocaine, Ecstasy, heroin, or psychedelics. Arab ethnicity and cigarette smoking were the strongest predictors of argileh use; however, a substantial percentage of non-Arabs and nonsmokers also had tried argileh. CONCLUSIONS: Findings suggest that, in comparison with other substances, the prevalence of argileh use is high among college students in the United States. Physical health implications of these findings are discussed.
