Activity

In this study, 76 μm polyoxymethylene (POM) strips were evaluated as a passive air sampler (PAS) for monitoring the volatile emissions from dredged material placed in confined disposal facilities (CDF). Laboratory evaluations were used to assess the uptake kinetics, average equilibrium time, and estimate the POM-air partition coefficients (KPOM-A) of 16 PCB congeners. The uptake kinetics defined the effective averaging time for air sampling and ranged from about a week for dichlorobiphenyls to 2 weeks or more for tetra- and pentachlorobiphenyls at ∼20 °C under internal mass transfer resistance control which was applicable for Log KPOM-A less then 8. The measured Log KPOM-A for PCBs ranged from 5.65 to 9.34 and exhibited an average deviation of 0.19 log unit from the theoretical value of KPOM-W/KAW. The PAS approach was then tested with a preliminary field application (n = 17) at a CDF allowing equilibration over 42 days. The field application focused on lower congener PCBs as a result of the estimated increase in KPOM-A and longer uptake times expected at the low ambient temperatures during the field study (average of 3.5 °C). Total PCB air concentrations around the CDF averaged 0.32 ng/m3 and varied according to proximity to placement of the dredged materials and predominant wind directions. Average PAS concentration of low congener number PCBs (15, 18, 20/28, 31) were compared to available high volume air sampler (HVAS) measurements. The PAS concentrations were within 20% of HVAS in the dominant north and south directions and showed similar trends as east and west HVAS samplers although PAS concentrations were as much as an order of magnitude below the west HVAS.Objective We aim to evaluate the accuracy, quality, and readability of online patient information concerning fibroids. Study design We searched the most popular Internet search engine Google.com. We developed a search strategy in consultation with patients with fibroids, to identify relevant websites. Two independent authors screened the search results. Websites were evaluated using validated instruments across three domains, including assessments of [1] quality (DISCERN instrument; range 0-85); [2] readability (Flesch-Kincaid instrument; range 0-100); and [3] accuracy. Accuracy was assessed using evidence-based statements. We summarised this data narratively including the use of figures and tables. Results We identified 750 websites, of which 48 were included. Over a third of websites did not attribute authorship and almost half the included websites did not report the sources of information or academic references. No website provided written patient information in line with recommendations from the American Medical Association. A minority (18%) of websites were assessed as high quality. Twelve webpages provided only accurate statements. Available information was, in general, skewed towards the surgical management of fibroids. No website scored highly across all three domains. Conclusion In the unlikely event that a website reports high quality and accurate health information, it is typically challenging for a lay audience to comprehend. Healthcare professionals and the wider community, should inform women with fibroids of the risk of outdated, inaccurate, or even dangerous information online. The implementation of an Information Standard certification will incentivise providers of online information to establish and adhere to codes of conduct.

However, the correlation between BPA levels and the outbreak of a cyanobacterial bloom remains largely unknown. GW4869 order In this study, the cellular and transcriptomic responses to BPA exposure were investigated. Exposure to a high concentration of BPA (50 μM) significantly inhibited the growth of cyanobacterial cells, with the highest inhibition ratio of 51.3%, photosynthesis, and the release of extracellular microcystin-LR (MC-LR) (p less then 0.05). However, exposure to low concentrations of BPA (0.1 and 1 μM) also affected these indicators, but the differences were closely related to the growth phase of the cyanobacterial cells. In addition, an imbalance between the antioxidant system and oxidative stress was observed in cyanobacteria under BPA stress. Folate biosynthesis, ABC transporters and ubiquinone and other terpenoid-quinone biosynthesis were the central metabolic pathways triggered by BPA stress. The up-regulated genes, including queC, VTE3 and PsbO were the controller of cellular growth and photosynthesis. The down-regulated genes, including VET4, MlaE and DnaA were potential biomarkers of oxidative damage. The up- and down-regulated genes, including CA, Ppc and CyoE were the main regulators of energy generation. The findings will provide important insights into the role of endocrine disruptors in the frequent outbreak of cyanobacterial blooms.
