omega-3 fatty acids

A family of long-chain polyunsaturated fatty acids, primarily eicosapentaenoic (C20:5) and docosahexanenoic acid (C22:6). Increased dietary omega-3 fatty acids are cardioprotective and have a positive impact on inflammatory conditions, interfering with the production of mediators of inflammation—including leukotrienes, platelet-activating factor, interleukin-l and tumour necrosis factor; increased consumption of dietary omega-3FAs and/or fish is reported to benefit patients with chronic inflammatory conditions, including rheumatoid arthritis, ulcerative colitis and chronic obstructive pulmonary disease. Following ingestion, omega-3FAs are rapidly incorporated into phospholipids of plasma and blood vessels; they decrease plasma levels of VLDL-cholesterol, decrease platelet aggregation, cause vasodilation and protect against coronary artery disease and atherosclerosis.

Executive Order #40 directs the Wisconsin Department of Natural Resources (DNR) to take additional steps to address PFAS contamination.
Jason will present 'Classification and Grouping of PFAS for Environmental Risk Assessment.' He and Jessica will present posters entitled 'Guidance for Assessing the Ecological Risks of Threatened and Endangered Species at Aqueous Film Forming Foam (AFFF)-Impacted Sites' and 'Framework for Assessing Risks to Threatened and Endangered Aquatic Life at PFAS Impacted Sites,' respectively, highlighting the 'Guidance for Ecological Risk Assessment of PFAS' that they developed for the Department of Defense under the Strategic Environmental Research and Development Program (SERDP).
Participants provided blood and spot urine specimens and completed a structured interview regarding demographics, residence history, and potential sources of PFAS exposure.
Shelley Moore Capito, whose state of West Virginia was one of the first where PFAS contamination was linked to human health problems, said she voted for Wheeler's appointment in committee earlier this month only after he privately assured her the EPA would tackle the problem.
(5) The report cited evidence for a wide range of adverse health outcomes tied to PFAS exposure, including liver damage, thyroid disease, decreased fertility, obesity, asthma, hormone suppression, endocrine disruption, and testicular and kidney cancer.
PFOA and PFOS are the best-known members of the family of highly fluorinated compounds known as PFAS. Over time, exposure to these can be linked to kidney cancer, thyroid problems, high cholesterol and other alarming medical conditions.
All told, there are thousands of PFAS chemicals, and scientists are only just beginning to understand their effects on human health.
Although scientists are still learning about PFAS, the technology for measuring all sorts of compounds in water and air samples has never been better.
To investigate whether PFAS exposure may be affecting kidney health, John Stanifer of Duke University and his colleagues searched the medical literature for relevant studies.
EPA testing from 2013 to 2015 found significant amounts of PFAS in public water supplies in 33 U.S.
PFAS repel water and oil (hydrophobic and lipophobic), are heat tolerant, and are very persistent in the environment.
Fetal alcohol syndrome (FAS) and the less severe fetal consequences of maternal drinking, collectively described as fetal alcohol spectrum disorders (FASD) than FAS/partial FAS (PFAS), are endemic in impoverished communities of the Western and the Northern Cape provinces of South Africa (SA).
