Toxic2
  • Plants containing more than 5 ppm selenium are potentially toxic in cattle. (usda.gov)
  • Given the difficulty with these processes, many facilities have turned to biological-based treatment, which transforms the selenium from a soluble and toxic form to a precipitate that can be safely handled and disposed. (watertechonline.com)
Complex2
  • The structure of black selenium is irregular and complex and consists of polymeric rings with up to 1000 atoms per ring. (wikipedia.org)
  • Since Selenium is complex for some, you may have to spend time and money learning how to use it properly, or you may have to pay someone else to help with training and support. (developer.com)
Placebo2
  • The study was stopped prematurely when an interim analysis revealed no general benefits, and a slightly higher progression-free survival in the placebo group compared with the selenium group. (nutraingredients.com)
  • 165 received 200µg Selenium + 200mg Q10 daily, and 161 received placebo. (vitalraadet.dk)
Insoluble1
  • The process continues through selenite to form insoluble elemental selenium at the outer membranes of the microbes. (watertechonline.com)
Organic1
  • Selenium can also be detected in the Ingestion of organic and inorganic forms absorbed through the gastrointestinal feces, hair, and nails. (cdc.gov)
Zinc2
  • Excess zinc is associated with gastrointestinal disturbances while chronic toxicity can lead to anaemia, neutropenia and bone abnormalities, whilst excess selenium is associated with nail-abnormalities, skin lesions and changes in peripheral nerves. (nutraingredients.com)
  • When investigating the difference between labelled and measured values, it was found that most zinc (86%) and selenium (78%) samples contained less of the nutrient than the labelled value, while fewer zinc (9.5%) and selenium (17%) samples contained more of the nutrient than the labelled value indicated. (nutraingredients.com)
Deficient1
  • There is mixed evidence as to whether supplementing with selenium can help reduce the risk of cancer: It may only help those deficient in selenium, while it may be potentially harmful for others (see What It Does ). (consumerlab.com)
Deficiencies1
  • Selenium deficiencies in the Keshan region in northeast China were severe enough to spur a form of heart disease called cardiomyopathy, now called Keshan's disease. (livescience.com)
Nutrients1
  • A balance of nutrients is required by our bodies to maintain good health, and selenium (Se) is an important one that often gets overlooked. (zrtlab.com)
Thyroid gland3
  • In 2003 a French study investigated the size of the thyroid gland compared to selenium consumption. (naturalnews.com)
  • Selenium (Se) deficiency is said to contribute to the atrophy of the thyroid gland in certain endemic goiter areas in Africa. (lu.se)
  • Selenium is also necessary for the thyroid gland to function normally. (msdmanuals.com)
Automation12
  • Selenium is an open-source framework for web testing automation that is quite popular with developers and QA teams. (developer.com)
  • In this review, we will break down the Selenium automation tool in terms of its features, pricing, advantages, and disadvantages to help determine if it is the right fit for you. (developer.com)
  • And if Selenium is not your ideal web testing automation tool, we will also reveal its top alternatives to give you some flexibility when shopping around. (developer.com)
  • Selenium is one of the top web testing automation tools on the market. (developer.com)
  • Selenium is a valuable testing automation tool for Agile and DevOps teams, developers, quality assurance professionals, software testers, and users with programming skills. (developer.com)
  • As mentioned, the Selenium automation tool is open-source. (developer.com)
  • Developers with limited budgets will enjoy the fact that the Selenium automation tool is open-source and free to use. (developer.com)
  • The normal compensation of a Selenium Automation Engineer is $81,405 annually. (quickstart.com)
  • Selenium is a browser automation library. (npmjs.com)
  • Selenium, an open source suite of tools and libraries, is one of the most popular test automation frameworks used by testers and developers around the world to automate web browser testing. (isqi.org)
  • The A4Q Certified Selenium 4 Tester Foundation certification connects relevant test automation theory with practical application for the effective use of Selenium in creating automated tests for web applications. (isqi.org)
  • It is aimed at test professionals, test automation engineers, and developers who desire an understanding of how to design, implement and maintain automated solutions using Selenium. (isqi.org)
Integrations1
  • Frequent updates and bug fixes from the Selenium team are quite helpful, as are its integrations with testing frameworks for improved reporting and test structure. (developer.com)
Cancers2
Dietary1
  • So just play it safe and encourage your human to eat iodized salt and seafood as the major dietary sources of iodine or plant foods containing selenium. (cdc.gov)
Researchers2
  • Researchers concluded that selenium may protect against both goiter and thyroid disease. (naturalnews.com)
  • In this current study, published in the journal Free Radical Biology and Medicine, the researchers observed that selenium deficiency is also associated with an increased risk of developing heart failure in individuals who do not have a known history of heart disease. (lu.se)
20191
  • Already in 2019, our research group demonstrated that selenium deficiency is linked to a worsened prognosis in patients with established heart failure, says Martin Magnusson, cardiologist at Skåne University Hospital, adjunct professor at Lund University, and Clinical Fellow at the Wallenberg Center for Molecular Medicine. (lu.se)
Amino acid2
  • sometimes called selenium monomethionine) is formed in plants when selenium substitutes for sulfur during synthesis of the amino acid methionine, and becomes incorporated into proteins in place of methionine. (zrtlab.com)
  • Selenocysteine, a selenium-containing amino acid. (zrtlab.com)
