METHODS: Adolescent cigarette smokers 14-18 years old (N=162) were recruited from medical, school, and community settings and randomly assigned to enhanced MI or brief advice (BA) for smoking cessation. MI comprised an in-person individual session, a telephone booster session one week later, and a brief telephone-based parent intervention. BA consisted of standardized brief advice to quit smoking. Assessments occurred at baseline, post-treatment and at 1-, 3-, and 6-month follow ups. RESULTS: Biochemically-confirmed 7-day point prevalence abstinence rates were low (e.g., 4.5% for MI; 1.4% for BA at 1 month) and did not differ significantly by group at any follow up. Only those in MI reported significant decreases in cigarettes smoked per day (CPD) from baseline to 1 month. At 3 and 6 months, smokers in both groups reported significantly reduced CPD with no differences between groups. MI reduced perceived norms regarding peer and adult smoking rates, while BA had no effect on normative perceptions. No group differences emerged for self-reported motivation or self-efficacy to quit smoking. CONCLUSIONS: Findings support the efficacy of MI for addressing normative misperceptions regarding peer and adult smoking and for modestly reducing CPD in the short-term; however, these effects did not translate to greater smoking abstinence. MI may have more promise as a prelude to more intensive smoking intervention with adolescents than as a stand-alone intervention.

Although the existing laws ban indoor smoking in public places in Sri Lanka, the level of compliance is unknown. METHODS: Fine particulate matter (PM(2.5)) levels in 20 public places in Colombo, Sri Lanka were measured by a PM monitor (Model AM510-SIDEPAK Personal Aerosol Monitor). Different types of businesses (restaurants, bars, cafes, and entertainment venues) were selected by purposive sampling. Only the places where smoking was permitted were considered. RESULTS: The average indoor PM(2.5) ranged from 33 to 299 microg/m(3). The average outdoor PM(2.5) ranged from 18 to 83 microg/m(3). The indoor to outdoor PM(2.5) ratio ranged from 1.05 to 14.93. In all venues, indoor PM(2.5) levels were higher than the Sri Lankan ambient PM(2.5) standard of 50 microg/m(3). All indoor locations had higher PM(2.5) levels as compared to their immediate outdoor surroundings. CONCLUSION: The study highlights the importance of improving ventilation and enforcing laws to stop smoking in public places.

To investigate genetic factors controlling this complex trait, a strawberry mapping population derived from genotype '1392', selected for its superior flavor, and '232' was profiled for volatile compounds over 4 years by headspace solid phase microextraction coupled to gas chromatography and mass spectrometry. More than 300 volatile compounds were detected, of which 87 were identified by comparison of mass spectrum and retention time to those of pure standards. Parental line '1392' displayed higher volatile levels than '232', and these and many other compounds with similar levels in both parents segregated in the progeny. Cluster analysis grouped the volatiles into distinct chemically related families and revealed a complex metabolic network underlying volatile production in strawberry fruit. Quantitative trait loci (QTL) detection was carried out over 3 years based on a double pseudo-testcross strategy. Seventy QTLs covering 48 different volatiles were detected, with several of them being stable over time and mapped as major QTLs. Loci controlling gamma-decalactone and mesifurane content were mapped as qualitative traits. Using a candidate gene approach we have assigned genes that are likely responsible for several of the QTLs. As a proof of concept we show that one homoeolog of the O-methyltransferase gene (FaOMT) is the locus responsible for the natural variation of mesifurane content. Sequence analysis identified 30 bp in the promoter of this FaOMT homoeolog containing putative binding sites for basic/helix-loop-helix, MYB, and BZIP transcription factors. This polymorphism fully cosegregates with both the presence of mesifurane and the high expression of FaOMT during ripening.

There has been a significant increase in immune-compromised, diabetic and/or elderly patients, also with venous access, with a subsequent increase in Candida species isolated from bloodstream infections. In 2009-2010 in the hospitals of Mestre and Venice we isolated 123 Candida species from bloodstream infections: 59 Candida albicans, 28 Candida parapsilosis, 12 Candida glabrata, 9 Candida tropicalis, and 4 Geotrichum capitatum, while the 11 others belong to 8 different species. We calculated MIC for the following antifungal agents: fluconazole, itraconazole, voriconazole, 5-flucytosine, amphotericin B and caspofungin.

Benzo[a]pyrene, chrysene and pyrene were employed as model compounds and spiked to smoked fish to assess the extraction procedure. Several parameters, including the nature and volume of hydrolysis, extracting and disperser solvents, microwave time and pH, were optimized. In the optimum condition for MAE, 1g of fish sample was extracted in 12 mL KOH (2M) and ethanol with a 50:50 ratio in a closed-vessel system. For DLLME, 500 muL of acetone (disperser solvent) containing 100 muL of ethylene tetrachloride (extraction solvent) was rapidly injected by syringe into 12 mL of the sample extract solution (previously adjusted to pH 6.5), thereby forming a cloudy solution. Phase separation was performed by centrifugation and a volume of 1.5 muL of the sedimented phase was analyzed by GC-MS in select ion monitoring (SIM) mode. Satisfactory results were achieved when this method was applied to analyze the PAHs in smoked fish samples. The MAE-DLLME method coupled with GC-MS provided excellent enrichment factors (in the range of 244-373 for 16 PAHs) and good repeatability (with a relative standard deviation between 2.8 and 9%) for spiked smoked fish. The calibration graphs were linear in the range of 1-200 ng g(-1), with the square of the correlation coefficient (R(2))>0.981 and detection limits between 0.11 and 0.43 ng g(-1). The recoveries of those compounds in smoked fish were from 82.1% to 105.5%. A comparison of this method with previous methods demonstrated that the proposed method is an accurate, rapid and reliable sample-pretreatment method that gives very good enrichment factors and detection limits for extracting and determining PAHs from smoked fish.

After enzymatic deconjugation, urine samples were extracted by liquid-liquid extraction (LLE) and OH-PAHs were analyzed by HPLC/MS/MS operated in negative electrospray ionization (ESI) and multiple reaction monitoring (MRM) mode. LLE was conducted with the solvent mixture of pentane and toluene, which reduced the matrix interferences and enhanced the method sensitivity significantly. Deuterated and (13)C-labeled analogs are used as internal standards. Calibration curves of all target analytes shows favorable linearity within the concentration range of 5.9-15,000.0 ng/L for different OH-PAHs with the regression coefficients above 0.993. The limits of detection (LODs) in pooled urine ranged from 1.72 to 17.47 ng/L, which were much lower than those obtained by a gas chromatography/high resolution mass spectrometry (GC/HRMS) method. The method shows satisfactory accuracy and precision when analyzing three different levels of OH-PAHs spiked in pooled urine. Except for 1-hydroxynaphthalene, recoveries of other OH-PAHs were in the range of 100 +/- 20% with a variation coefficient of less than 13%. The measurement of OH-PAHs from a QC sample of the Centers for Disease Control and Prevention (CDC) generated results close to the values measured by CDC. This method has been successfully employed in the California Biomonitoring Program. Descriptors Links Book Title Database Publisher Data Source Authors Fan,R., Ramage,R., Wang,D., Zhou,J., She,J.

However, nitrogen (N) cycling impacts among forest types are not well known. We quantified beetle-induced changes in forest structure, soil temperature, and N cycling in Douglas-fir (Pseudotsuga menziesii) forests of Greater Yellowstone (WY, USA), and compared them to published lodgepole pine (Pinus contorta var. latifolia) data. Five undisturbed stands were compared to five beetle-killed stands (4-5 years post-outbreak). We hypothesized greater N cycling responses in Douglas-fir due to higher overall N stocks. Undisturbed Douglas-fir stands had greater litter N pools, soil N, and net N mineralization than lodgepole pine. Several responses to disturbance were similar between forest types, including a pulse of N-enriched litter, doubling of soil N availability, 30-50 % increase in understory cover, and 20 % increase in foliar N concentration of unattacked trees. However, the response of some ecosystem properties notably varied by host forest type. Soil temperature was unaffected in Douglas-fir, but lowered in lodgepole pine. Fresh foliar %N was uncorrelated with net N mineralization in Douglas-fir, but positively correlated in lodgepole pine. Though soil ammonium and nitrate, net N mineralization, and net nitrification all doubled, they remained low in both forest types ( Descriptors Links Book Title Database Publisher Data Source Authors Griffin,J.M., Turner,M.G.

Our results showed that caxiri fermentation is invariably associated with the following: (i) an increase in the total microbial population, with yeast being the largest group detected; (ii) a decrease in reducing sugars, malic, tartaric, succinic, oxalic and propionic acid; and (iii) a final product characterised by a high content of ethanol and a high concentration of lactic acid. The microbial community dynamics were investigated by culture-based and culture-independent approaches. Fermentation was assisted by a complex microbial community that changed in structure and composition during the fermentative process. The bacterial population ranged from 3.05 to 5.33 log/mL, and the yeast population varied from 3.27 log CFU/mL to 7.34 log CFU/mL, showing that yeasts dominated the fermentation process after 48 h. A total of 343 colonies of bacteria and 205 colonies of yeasts were isolated and initially grouped by Amplified Ribosomal DNA Restriction Analysis (ARDRA) and by biochemical features. Phylogenetic analysis of the 16S rRNA gene sequences of representative isolates showed that the bacteria were mainly represented by endospore-forming low-G+C content Gram-positive bacilli (Bacillus spp.; 61.5% of the isolates), with Bacillus pumilus, Bacillus spp. (Bacillus cereus group), and Bacillus subtilis being the main species identified. The species Sphingomonas sp. and Pediococcus acidilactici were also found. The dominant yeast identified was Saccharomyces cerevisiae. Rhodotorula mucilaginosa, Pichia membranifaciens, Pichia guilliermondii and Cryptococcus luteolus were also found. According to the Polymerase Chain Reaction and Denaturing Gradient Gel Electrophoresis (PCR-DGGE) analysis, the microbial communities present during fermentation were probably from the raw materials, ambient or present on the utensils used during beverage preparation. The results indicated the necessity to combine both culture-dependent and culture-independent methods for a better description of the microbial communities in indigenous starch fermentations. Also, pH values decreased from 4.76 to 3.15 during fermentation. The ethanol concentration was 83.9 g/L and lactic acid reached 27.89 g/L by the end of the fermentation process.

The electropolymerization process was carried out at a constant deposition potential, applied to the corresponding aqueous electrolyte containing aniline and silica nanoparticles. The scanning electron microscopy (SEM) images showed the non-smooth and the porous surface structure of the prepared nanocomposite. The applicability of the new fiber coating was examined by headspace-solid phase microextraction (HS-SPME) of some environmentally important polycyclic aromatic hydrocarbons (PAHs), as model compounds, from aqueous samples. Subsequently, the extracted analytes were transferred into a gas chromatography (GC) by thermal desorption. Parameters affecting the synthesizing and extraction processes including the voltage of power supply, the weight ratio of components, the time of electrodeposition, extraction time and temperature, the ionic strength, and desorption temperature and time were optimized. Eventually, the developed method was validated by gas chromatography-mass spectrometry (GC-MS). At the optimum conditions, the relative standard deviation (%RSD) values for a double distilled water spiked with the selected PAHs at 40 ng L(-1) were 6-13% (n=3) while the limit of detection (LOD) results were between 1 and 3 ng L(-1). The calibration graphs were linear in the concentration range from 20 to 4000 ng L(-1) (R(2)>0.995). Finally the developed method was applied to the analysis of Kalan dam, rain and tap water samples and the relative recovery values were found to be in the range of 76-109%, under optimized conditions. In addition, the synthesis of the nanocomposite coating was carried out conveniently while it is rather inexpensive, easy, simple, rapid and highly durable and can be used frequently.

However, no analyses have examined how delivery rate modifies the strength of odds ratio (OR) trends with total exposure, i.e., the impact on the OR for a fixed total exposure of high exposure rate for short duration compared with low exposure rate for long duration. METHODS: The authors pooled data from 12 case-control studies from the Barrett's Esophagus and Esophageal Adenocarcinoma Consortium (BEACON), including 1242 (EAC), 1263 (EGJA) and 954 (ESCC) cases and 7053 controls, modeled joint ORs for cumulative exposure and exposure rate for cigarette smoking and alcohol consumption, and evaluated effect modification by sex, body mass index (BMI), age and self-reported acid reflux. RESULTS: For smoking, all sites exhibited inverse delivery rate effects, whereby ORs with pack-years increased, but trends weakened with increasing cigarettes/day. None of the examined factors modified associations, except for ESCC where younger ages at diagnosis enhanced smoking effects (P Descriptors Links Book Title Database Publisher Data Source Authors Lubin,J.H., Cook,M.B., Pandeya,N., Vaughan,T.L., Abnet,C.C., Giffen,C., Webb,P.M., Murray,L.J., Casson,A.G., Risch,H.A., Ye,W., Kamangar,F., Bernstein,L., Sharp,L., Nyren,O., Gammon,M.D., Corley,D.A., Wu,A.H., Brown,L.M., Chow,W.H., Ward,M.H., Freedman,N.D., Whiteman,D.C.
