They are obtained by a condensation reaction between epichlorohydrin with bisphenol A and bisphenol F, respectively. These potential endocrine disrupting chemicals are able to enter the food chain and to reach the intestinal epithelium, causing structural and functional damages. The human colorectal adenocarcinoma cell line Caco-2 is a widely used in vitro model of the intestinal cells. The aim of this study was to characterize BADGE and BFDGE toxicity in Caco-2 cells, in particular, at the cellular and molecular level. Using several approaches, we characterized BADGE- and BFDGE-induced cell toxicity in Caco-2 cells. The treatment was done using different concentrations up to cytotoxic doses and different times of exposure to the agents. We evaluated the effect of these compounds on cell morphology, cell detachment, cell proliferation, F-actin disruption and plasma membrane integrity. Both compounds are able to induce morphological changes, cell detachment from the substratum and to inhibit cell proliferation, being these effects time and dose-dependent. Moreover, BADGE and BFDGE induce F-actin depolymerization, this effect is very potent at 24 h of incubation with the agents and a complete F-actin disruption can be observed at 200 microM BADGE or BFDGE. In addition, cell integrity is not damaged, since neither propidium iodide uptake nor LDH release takes place in Caco-2 cells exposed to high doses of these agents for 24 h.

In this study, 163 bacterial isolates associated with this starter samples were identified and their population distribution was investigated by amplified ribosomal DNA restriction analysis (ARDRA), 16S rDNA sequencing and randomly amplified polymorphic DNA (RAPD) analysis. This acidic starter (pH 4.5+/-0.15) was dominated by a characteristic association of Bacillus and lactic acid bacteria (LAB) together. The population distribution of dominant species were Bacillus subtilis 29.3%, Bacillus cereus 35.7%, Bacillus pumilus 2.6%, Lactobacillus brevis 9.6%, Lactobacillus plantarum 5.1%, Carnobacterium sp. 11.9%, Enterococcus faecium 1.2% and Pseudomonas fluorescens 4.6%. Alarming population load (10(6)-10(7)cfu/ml) of B. cereus in 87% of starter samples studied should raise concern regarding biosafety of soidon consumption. PCR amplification of 16S-23S rDNA intergenic transcribed spacer (ITS) region and ITS-RFLP profiles revealed a high diversity with eight subgroups in B. subtilis, five subgroups in B. cereus and three subgroups in L. brevis isolates. The most abundant B. subtilis subgroup IB.1 distributed in most of the samples showed very less clonal variability during RAPD analysis. The molecular methods used in this study identified the dominant strains of Bacillus and LAB distributed in most of the starter samples. These dominant strains of B. subtilis, L. brevis and L. plantarum would allow for developing a defined starter culture for the production of quality soidon.

Cultivation-dependent analyses (PCR-amplified ribosomal DNA restriction analysis and rRNA gene sequencing) and cultivation-independent analyses (PCR-DGGE, qPCR and Illumina amplicon sequencing) were conducted on the time series samples collected from three independent indigenous soidon fermentation batches. The current findings revealed three-phase succession of autochthonous lactic acid bacteria to attain a stable ecosystem within 7 days natural fermentation of bamboo shoots. Weissella spp. (Weissella cibaria, uncultured Weissella ghanensis) and Lactococcus lactis subsp. cremoris predominated the early phase (1-2 days) which was joined by Leuconostoc citreum during the mid-phase (3 days), while Lactobacillus brevis and Lactobacillus plantarum emerged and became dominant in the late phase (5-7 days) with concurrent disappearance of W. cibaria and L. lactis subsp. cremoris. Lactococcus lactis subsp. lactis and uncultured Lactobacillus acetotolerans were predominantly present throughout the fermentation with no visible dynamics. The above identified dominant bacterial species along with their dynamics can be effectively utilized for designing a starter culture for industrialization of soidon production. Our results showed that a more realistic view on the microbial ecology of soidon fermentation could be obtained by cultivation-dependent studies complemented with cultivation-independent molecular approaches. Moreover, the critical issues to be considered for reducing methodological biases while studying the microbial ecology of traditional food fermentation were also highlighted with this soidon fermentation model.

Thus, it is important to characterize the resistance genetic elements of waterborne E. coli. It is also important to identify the predominant clonal groups/phylogroups represented by resistant strains to understand the epidemiology of antibiotic resistant E. coli in natural environments, and to identify the role of well-established genotypes in the spread of resistance in a particular geographical area through natural environments. In the present investigation, E. coli strains (n=126) isolated from various points along the river Yamuna traversing through the National Capital Territory of Delhi (India) were grouped phylogenetically. A collection of 61 strains representing all phylogroups was investigated for extended-spectrum beta-lactamase (ESBL) and AmpC production. blaTEM, blaSHV and blaCTX-M genes were detected and analyzed, promoter/attenuator mutations associated with chromosomally-mediated AmpC overexpression were identified, and plasmid-mediated ampC was determined. blaTEM was the most widespread (100%) gene followed by bla(CTX-M) (16%), and plasmid-mediated ampC (3%). bla(CTX-M-15) and bla(CMY-42) were identified as the genes encoding CTX-M type ESBL and CIT type AmpC beta-lactamases, respectively. CTX-M-15 ESBL phenotype was most common in phylogroup D (50%), followed by phylogroups B1 (30%), and A (20%). E. coli that produce plasmid-mediated AmpC were rare and present only in phylogroup D. Presence of multi beta-lactam resistance, bla(CTX-M-15) and bla(CMY-42) in waterborne E. coli belonging to virulence-associated phylogroup D highlights the need for routine surveillance of resistance determinants in aquatic environments. This is also the first report for the presence of bla(CMY-42) in waterborne E. coli.

Little is known about public perceptions of these policies and factors that predict their support or opposition. METHODS: Using a sample of US adults from Amazon Mechanical Turk in May 2015, this paper identifies beliefs about the benefits and costs of regulating e-cigarettes and identifies which of these beliefs predict support for e-cigarette restricting policies. RESULTS: A higher proportion of respondents agreed with 8 different reasons to regulate e-cigarettes (48.5% to 83.3% agreement) versus 7 reasons not to regulate e-cigarettes (11.5% to 18.9%). The majority of participants agreed with 7 out of 8 reasons for regulation. When all reasons to regulate or not were included in a final multivariable model, beliefs about protecting people from secondhand vapor and protecting youth from trying e-cigarettes significantly predicted stronger support for e-cigarette restricting policies, whereas concern about government intrusion into individual choices was associated with reduced support. DISCUSSION: This research identifies key beliefs that may underlie public support or opposition to policies designed to regulate the marketing and use of e-cigarettes. Advocates on both sides of the issue may find this research valuable in developing strategic campaigns related to the issue. IMPLICATIONS: Specific beliefs of potential benefits and costs of e-cigarette regulation (protecting youth, preventing exposure to secondhand vapor, and government intrusion into individual choices) may be effectively deployed by policy makers or health advocates in communicating with the public.

Barrett's esophagus (BE) is an associated premalignant lesion. Current preventative efforts rely on endoscopic screening of individuals with gastroesophageal reflux disease (GERD) symptoms and surveillance endoscopy for those with BE. However, some recent studies have found a high prevalence of BE in patients without GERD, and others have found little or no association with GERD. We hypothesized that studies of higher-quality design show weaker associations of GERD with BE, and that GERD is only weakly associated with short-segment Barrett's esophagus (SSBE). METHODS: We performed a systematic literature search in multiple online electronic databases regardless of language. Eligible studies required visualization of columnar mucosa and histological confirmation of intestinal metaplasia, and GERD symptoms ascertained by questionnaire or interview. The highest-quality sampling design was defined a priori by both cases and controls identified among unselected research volunteers ("research design") rather than by patients selected for endoscopy for clinical indications ("clinical design"), which introduces selection and ascertainment bias. A priori, heterogeneity was defined by Cochrane's Q P<0.20 and the inconsistency index (I(2); 25% low, 50% moderate, and 75% high). Heterogeneity of results can reflect significant differences in study design or effect modification by strata of outcomes. RESULTS: Systematic review identified 13,392 citations. Evaluation identified 108 potentially relevant journal articles, of which 26 met eligibility. Of these, 14 studies identified cases of BE and controls based on clinical indication ("clinical design"), and 6 used the "research design." The remaining six studies identified cases of BE from patients undergoing endoscopy for clinical indication and controls among patients without known BE ("cases clinical/controls research"). The summary odds ratio (OR) for the association of GERD with BE from all studies was 2.90 (95% confidence interval (CI), 1.86-4.54), but the results were very heterogeneous (P=0.0001; I(2)=89%). When stratified by BE length and sampling design, the studies with clinical design showed substantial, but heterogeneous, associations with SSBE (OR, 2.38; 95% CI, 1.21-4.70; P=0.02; I(2)=62%), and stronger and homogeneous association with long-segment BE (LSBE; fixed effects OR, 2.96; 95% CI, 1.69-5.19; P=0.25; I(2)=25%). In the research study design, stratifying by length of BE resolved the heterogeneity and showed a strong association between GERD and LSBE (fixed effects OR, 4.92; 95% CI, 2.01-12.0; P=0.30; I(2)=19%) and no association with SSBE (fixed effects OR, 1.15; 95% CI, 0.763-1.73; P=0.84; I(2)=0%). Funnel plots showed potential evidence for bias against dissemination of small negative studies. CONCLUSIONS: In the highest-quality studies, GERD symptoms are not associated with SSBE, but increased the odds of LSBE by fivefold. GERD symptoms can serve as a reliable predictor of LSBE, but not SSBE. If SSBE is considered worthy of identification, then current screening practices do not select patients at risk for endoscopy, and alternative methods of selection for screening need to be developed.

The effects of lead are well known and range from delayed and adversely affected neurodevelopment to severe health outcomes including seizures, coma, and death. This article reviews the childhood effects of lead poisoning, the approach being taken to the problem in the United States, and the obstacles faced by developing nations in dealing with lead exposure. The United States has attacked the childhood lead poisoning problem by attempting to eliminate sources of exposure, including gasoline, solder in water pipes and cans, and industrial emissions. These actions have resulted in a dramatic reduction in the number of children with elevated blood lead levels in the United States over the last two decades. However, many developing countries are just beginning to address the problem. Successful efforts will need to incorporate epidemiologic methods, source identification, enforced regulations, and a long-term government commitment to eliminating lead as a threat to the next generation of children.

A geometric mean concentration of 3.76 +/- 1.69 micrograms Pb/dl was found in 9189 neonates, being 64% of the total birth cohort. The median concentration was 3.59 micrograms/dl. 4.7% of the children showed concentrations of above 10 micrograms/dl. Lead concentrations of twins showed a strong linear correlation (r = + 0.94). They were higher than those of singleton births (p = 0.02). Lead concentrations in neonates were significantly associated with the age of the mother and with the birthweight of the newborn. Seasonal differentials were significant with higher values in summer (4.39 +/- 1.8 micrograms Pb/dl) compared to winter (3.25 +/- 1.5 micrograms/dl). Duration of daily participation in road traffic was independent of blood lead concentrations. Potential occupational lead exposure of a member of the household was also no significant risk factor for higher lead concentration in the newborn. Family homes constructed before 1955 and those with lead water pipes were associated with significant increases of lead concentrations in neonates. Neighborhood was also significantly associated, with higher values in those living by main roads. In the southern part of the district lead concentrations were about 10% higher than in the northern part. Concentrations in neonates coming from cities were the same as in those coming from rural areas. Newborns from old lead mining and processing areas in the Harz mountains, in particular those coming from Oker-Harlingerode, had low lead concentrations in umbilical cord blood.

METHODS: Young adult students attending undergraduate (within the 4-year program) and graduate (only first-year students) colleges in Zhejiang Province were recruited between November 2010 and March 2011 to participate in the self-report survey study. The questionnaire was designed to collect data regarding demographics (sex and age), general health [weight and height, to calculate body mass index (BMI)], and physical episodes related to gastrointestinal disorders. Diagnosis of dyspepsia and irritable bowel syndrome (IBS) was made according to the Rome III criteria. Gastroesophageal reflux disease (GERD) was defined by episodes of heartburn and/or acid reflux that occurred at least once a week, according to the Montreal definition. RESULTS: Of 2520 students recruited for survey participation, only 1870 (males: 967; age range: 17-32 years, mean age: 21.3 years) returned a completed questionnaire. One hundred and eight (5.67%) of the student participants fit the criteria for dyspepsia diagnosis.

Available constants for bulk chlorine decay are typically determined under static conditions. However, as for all fast reactions in water flows, chlorine consumption rates in drinking water pipes may be influenced by the existing mixing regimes, a function of flow turbulence, which is primarily controlled by flow velocity and pipe diameter. Flow velocities vary greatly in space and time in water transmission and distribution systems; pipe diameters are seldom uniform. Although both variables are readily available in the currently available network analysis simulators that implement chlorine models, such variations are not accounted for. Instead, a single preset decay rate constant is generally used for describing chlorine residual consumption throughout an entire system. In addition to highlighting how negligible PVC pipe wall chlorine consumption is, as such, this paper presents experimental evidence of a significant correlation between pipe flow velocity and bulk chlorine decay rates, and proposes a simple but effective approach to implement this dependency in current simulators.
