NH Arsenic Consortium Meeting, October 13, 8:30am-4:00pm
Please save the date for our annual meeting of the NH Arsenic Consortium to learn about the latest arsenic research and outreach. Actions to improve awareness and reduce exposure to arsenic in water and food also will be discussed. The meeting will be at the NH DES offices, 29 Hazen Drive in Concord, NH. More information will be available soon.
13th International Conference on Mercury as a Global Pollutant (ICMGP) Science to Policy Synthesis Workshop
On July 16, thirty scientists and policy stakeholders attended a day-long workshop, Integrating Mercury Research and Policy in a Changing World, as part of the ICMGP 2017 meeting. Organized and led by the Dartmouth SRP Research Translation Core, the workshop provided the opportunity for face-to-face communications between mercury science experts and national and international policymakers and stakeholders. Presentations by policymaker and stakeholder representatives identified questions and knowledge gaps in mercury research to be addressed in a series of 4 synthesis papers on different aspects of mercury pollution. The workshop culminated with a full-group discussion on how to translate these synthesis papers to have a bigger impact on mercury policy. A more detailed summary and photos are available here.
New Web Application Developed
Dartmouth Superfund Program Director Bruce Stanton, Superfund researcher Thomas Hampton, and lead author Katja Koeppen have developed a new web application, ScanGEO, that allows rapid meta-analysis of publicly available gene expression data. The application is freely accessible using this link. For more information, refer to the Applications Note.
Superfund Faculty and Trainees Attend MDI Applied Bioinformatics Course
30 Students and 7 faculty attended the July 15-20 Applied Bioinformatics Course at MDI Biological Laboratory. These included from left to right in photo: Stephen Costa (Dartmouth), Liviu Cengher (Dartmouth), Victoria Holden (Dartmouth), Bruce Stanton (Dartmouth, Course Co-Director), Zhongyou Li (Dartmouth), Ben King (University of Maine, Course Co-Director), Thomas Hampton (Dartmouth), Katja Koeppen (Dartmouth), Tiffany Sanchez (Columbia) and Anne Bozack (Columbia).
The Course provided hands-on training on major bioinformatics resources through the analysis of RNA-Seq data examining the effects of arsenic on the transcriptionla response oflung cells to bacterial infection, to find differentially expressed genes and investigate previously described functions of those genes and the pathways in which they are involved. Dartmouth Superfund Program Director Bruce Stanton was the Course Co-Director.
Arsenic and You Website Provides "Wealth of Information"
According to NIEHS' Environmental Factor e-newsletter, Dartmouth College Superfund Program's Arsenic and You website provides a "wealth of information on how people are exposed to arsenic and steps that they can take to reduce exposures". The website was developed to inform the public and answer questions about arsenic in water, food, and other sources.
Study Published on Effectiveness of Tabletop Water Pitcher Filters to Remove Arsenic
The study Effectiveness of Table Top Water Pitcher Filters to Remove Arsenic from Drinking Water by lead author Roxanna Barnaby, Dartmouth Superfund Research Program Director Bruce Stanton, researcher Brian Jackson, and Amanda Liefeld and Thomas Hampton from the Stanton Lab, tested five brands of tabletop water pitcher filters. The research was conducted because of the public health risk of arsenic contamination and the importance of identifying cost effective means for the public to remove arsenic from their drinking water. The paper is published in Environmental Research.
Paper Published on Arsenic Metabolites Following Seaweed Consumption
The paper Distinct Arsenic Metabolites Following Seaweed Consumption in Humans by lead author Vivien Taylor and researcher Margaret Karagas of the Dartmouth Superfund Program examines arsenic levels in seaweed consumed by humans. The paper was published in the journal Scientific Reports.
Study Examines Health Effects of Arsenic
The goal of the study Arsenic Alters Transcriptional Responses to Pseudomonas aeruginosa Infection and Decreases Antimicrobial Defense of Human Airway Epithelial Cells was to examine the effect of arsenic on gene expression in primary human bronchial epithelial (HBE) cells and to determine if arsenic altered epithelial cell responses to Pseudomonas aeruginosa, an opportunistic pathogen. The paper by lead author Britton Goodale and Dartmouth Superfund director Bruce Stanton is available online in the journal Toxicology and Applied Pharmacology.
