Abstract
Here, we investigate fine-root production, mortality and standing crop of Douglas-fir (Pseudotsuga menziesii) seedlings exposed to elevated atmospheric CO(2) and elevated air temperature. We hypothesized that these treatments would increase fine-root production, but that mortality would be greater under elevated temperature, leading to a smaller increase in standing crop. Seedlings were grown in outdoor, sun-lit controlled-environment chambers containing native soil. They were exposed in a factorial design to two levels of atmospheric CO(2) and two levels of air temperature. Minirhizotron methods were used to measure fine-root length production, mortality and standing crop every 4 wk for 36 months. Neither elevated atmospheric CO(2) nor elevated air temperature affected fine-root production, mortality, or standing crop. Fine roots appeared to root deeper in the soil profile under elevated CO(2) and elevated temperature. Low soil nitrogen (N) levels apparently limited root responses to the treatments. This suggests that forests on nutrient-poor soils may exhibit limited fine-root responses to elevated atmospheric CO(2) and elevated air temperature.

Abstract
Global climate change causes an increase in ambient air temperature, a major environmental factor influencing plant physiology and growth that already has been perceived at the regional scale and is expected to become even more severe in the future. In the present study, we investigated the effect of elevated ambient air temperature on the nitrogen metabolism of two interior provenances of Douglas fi r (Pseudotsuga menziesii var. glauca) originating from contrasting habitats, namely the provenances Monte Creek (MC) from a drier environment and Pend Oreille (PO) from a more humid environment. Three- to four-year-old seedlings of the two provenances were grown for 3 months in controlled environments under either control temperature (day 20 degrees C, night 15 degrees C) or high temperature (HT, 30/25 degrees C) conditions. Total nitrogen (N), soluble protein, chlorophyll and total amino acid (TAA) contents as well as individual amino acid concentrations were determined in both current-year and previous-year needles. Our results show that the foliar total N contents of the two provenances were unaffected by HT. Arginine, lysine, proline, glutamate and glutamine were the most abundant amino acids, which together contributed approximately 88% to the TAA pool of current- and previous-year needles. High temperature decreased the contents of most amino acids of the glutamate family (i.e., arginine, proline, ornithine and glutamine) in current-year needles. However, HT did not affect the concentrations of metabolites related to the photorespiratory pathway, such as [Formula: see text], glycine and serine. In general, current-year needles were considerably more sensitive to HT than previous-year needles. Moreover, provenance PO originating from a mesic environment showed stronger responses to HT than provenance MC. Our results indicate provenance-specific plasticity in the response of Douglas fir to growth temperature. Provenance-specific effects of elevated temperature on N-use efficiency suggest that origin might determine the sensitivity and growth potential of Douglas fir trees in a future warmer climate.

Abstract
The effect of hose permeability on toxicant yields for the narghile waterpipe is investigated, with special reference to the recent adoption of plastic as a hose construction material. Measurements of air infiltration rates for 23 leather and plastic hoses representing 11 types commonly available in Beirut, Lebanon were made, revealing that while leather hoses allowed significant outside air infiltration during a puff constituting up to 31% of the puff volume, plastic hoses were found to be air-tight, indicating that the smoke reaching the waterpipe user can be considerably more concentrated when delivered via a plastic hose. Total particulate matter (TPM), nicotine and carbon monoxide (CO) yields were compared when a waterpipe was machine smoked using a highly permeable leather and an air-tight plastic hose. It was found that the plastic hose resulted in similar yields of nicotine, but more than double the CO yielded with the highly permeable leather hose. Thus, even if narghile smokers titrate for nicotine intake, the use of a plastic hose will likely greatly increase the exposure to CO, a major causative agent in cardiovascular disease.

Abstract
OBJECTIVES: Waterpipe smoking is highly prevalent among university students, and has been increasing in popularity despite mounting evidence showing it is harmful to health. The aim of this study was to measure preferences for waterpipe smoking and determine which product characteristics are most important to smokers. SETTING: A large university in the Southeastern USA. PARTICIPANTS: Adult waterpipe smokers attending the university (N=367). DESIGN: Participants completed an Internet-based discrete choice experiment to reveal their preferences for, and trade-offs between, the attributes of hypothetical waterpipe smoking sessions. Participants were presented with waterpipe lounge menus, each with three fruit-flavoured options and one tobacco flavoured option, in addition to an opt out option. Nicotine content and price were provided for each choice. Participants were randomised to either receive menus with a text-only health-warning message or no message. OUTCOME MEASURES: Multinomial and nested logit models were used to estimate the impact on consumer choice of attributes and between-subject assignment of health warnings respectively. RESULTS: On average, participants preferred fruit-flavoured varieties to tobacco flavour. They were averse to options labelled with higher nicotine content. Females and non-smokers of cigarettes were more likely than their counterparts to prefer flavoured and nicotine-free varieties. Participants exposed to a health warning were more likely to opt out. CONCLUSIONS: Fruit-flavoured tobacco and lower nicotine content labels, two strategies widely used by the industry, increase the demand for waterpipe smoking among young adults. Waterpipe-specific regulation should limit the availability of flavoured waterpipe tobacco and require accurate labelling of constituents. Waterpipe-specific tobacco control regulation, along with research to inform policy, is required to curb this emerging public health threat.

Abstract
Following 42 days since the last Ebola virus disease (Ebola) patient was discharged from a Liberian Ebola treatment unit (ETU), September 3, 2015, marks the second time in a 4-month period that the World Health Organization (WHO) has declared Liberia free of Ebola virus transmission (1). The first confirmed Ebola cases in West Africa were identified in southeastern Guinea on March 23, 2014, and within 1 week, cases were identified and confirmed in Liberia (1). Since then, Liberia has reported 5,036 confirmed and probable Ebola cases and 4,808 Ebola-related deaths. The epidemic in Liberia peaked in late summer and early fall of 2014, when more than 200 confirmed and probable cases were reported each week .

Abstract
OBJECTIVES/HYPOTHESIS: Inner ear decompression illness is thought to be a rare phenomenon in recreational divers, isolated signs and symptoms of inner ear dysfunction usually being attributed to inner ear barotrauma. STUDY DESIGN: We present 11 cases of inner ear dysfunction in nine divers with inner ear decompression illness. RESULTS: All nine divers had significant right-to-left shunt as diagnosed by transcranial Doppler sonography. CONCLUSIONS: The authors thought that mechanism of causation in these cases may have been intravascular bubble emboli and that inner ear decompression illness may be more common among recreational divers than currently recognized. Failure to treat inner ear decompression illness with recompression therapy can result in permanent disability. Because the differential diagnosis between inner ear barotrauma and inner ear decompression illness can be impossible, the authors suggested that divers who present with inner ear symptoms following a dive should have recompression immediately after having undergone bilateral paracentesis.

Abstract
INTRODUCTION: Hookah (or waterpipe) use is increasing worldwide with implications for public health. Emerging adults (ages 18 to 25) have a higher risk for hookah use relative to younger and older groups. While research on the correlates of hookah use among emerging adults begins to accumulate, it may be useful to examine how transition-to-adulthood themes, or specific thoughts and feelings regarding emerging adulthood, are associated with hookah use. This study determined which transition-to-adulthood themes were associated with hookah use to understand the risk and protective factors for this tobacco-related behavior. METHODS: Participants (n=555; 79% female; mean age 22) completed surveys on demographic characteristics, transition-to-adulthood themes, hookah, and cigarette use. RESULTS: Past-month hookah use was more common than past-month cigarette use (16% versus 12%). In logistic regression analyses, participants who felt emerging adulthood was a time of experimentation/possibility were more likely to report hookah use. However, transition-to-adulthood themes were not statistically significantly related to cigarette use. CONCLUSIONS: The profile for hookah use may differ from that of cigarettes among emerging adults. Themes of experimentation/possibility should be addressed in prevention programs on college campuses and popular recreational spots where emerging adults congregate. These findings can inform future studies of risk and protective factors for hookah use among emerging adults.

Abstract
Bacteria form surface-attached biofilm communities in nature. In contrast to free-living cells, bacterial cells within biofilms resist sanitizers and antimicrobials. While building biofilms, cells physiologically adapt to sustain the otherwise lethal impacts of a variety of environmental stress conditions. In this development, the production and embedding of cells in extracellular polymeric substances plays a key role. Biofilm bacteria can cause a range of problems to food processing including reduced heat-cold transfer, clogging water pipelines, food spoilage and they may cause infections among consumers. Recent biofilm investigations with the aim of potential control approaches include a combination of bacterial genetics, systems biology, materials and mechanic engineering and chemical biology.

Abstract
The idea of clean nicotine delivery systems that would satisfy nicotine craving and promote smoking cessation has been considered as a possible public health tool for many years. Nicotine medications have been useful for smoking cessation but have not found widespread popularity among smokers, perhaps because of slow nicotine delivery and other sensory characteristics that differ from cigarettes. Traditional smokeless tobacco delivers as much nicotine as cigarettes and has been advocated for harm reduction but contains carcinogenic nitrosamines and has not been proven to promote cessation. Furthermore, there is concern that dual use of smokeless tobacco and cigarettes may inhibit quitting smoking. Newer oral dissolvable tobacco products contain lower levels of toxicants than other smokeless tobacco but also deliver much less nicotine and have not been popular with consumers. Electronic cigarettes that aerosolize nicotine without generating toxic tobacco combustion products have become quite popular and hold promise as a way to attract smokers away from cigarettes, although efficacy in promoting smoking cessation has not yet been demonstrated. There are concerns about safety of long-term use, and there is evidence that youth, including nonsmokers, are taking up e-cigarette use. E-cigarettes are marketed for use when one cannot smoke conventional cigarettes, and such use might result in more persistent cigarette smoking. Although their benefits and risks are being vigorously debated, e-cigarettes or other clean nicotine delivery devices could play an important role as an adjunct to a U.S. Food and Drug Administration regulatory intervention to make cigarettes less addictive and in this context could contribute to the end of cigarette smoking and smoking-induced disease.

Abstract
OBJECTIVE: A national surveillance system to track hookah use by adolescents does not exist. A growing body of evidence suggests that high school-aged students are experimenting with this form of tobacco. This study adds to the current literature by providing prevalence estimates and factors associated with hookah use among New Jersey high school students. METHOD: This study explores factors associated with hookah use using 2008 NJYTS data. The 2008 NJYTS was a self-reported, paper-and-pencil, cross-sectional survey of a representative sample of 3010 high school students. RESULTS: 9.7% of NJ high school students are current hookah users. Predictors of hookah use included those who identified as Asian, concurrent tobacco users, perceiving that cigars are safer than cigarettes, or perceiving that smoking looks cool. CONCLUSION: The prevalence of hookah use, higher likelihood of concurrent tobacco use among hookah users, and misperceptions of safety and popularity of hookah among NJ adolescents are cause for concern and action. The development and regular implementation of standardized hookah prevalence questions into our national and state surveillance systems, as well as targeted, state-specific youth education and prevention activities are essential to thwart this growing public health concern.
