Selenium is a component of the amino acids selenocysteine and selenomethionine. In humans, selenium is a trace element nutrient that functions as cofactor for glutathione peroxidases and certain forms of thioredoxin reductase. [1] Selenium-containing proteins are produced from inorganic selenium via the intermediacy of selenophosphate (PSeO 3 3 ...
Selenium deficiency occurs when an organism lacks the required levels of selenium, a critical nutrient in many species.Deficiency, although relatively rare in healthy well-nourished individuals, [1] can have significant negative results, [2] affecting the health of the heart and the nervous system; contributing to depression, anxiety, and dementia; and interfering with reproduction and gestation.
Jim Reed is depressed and tired of life old man living in an RV near the woods of Maine during the winter. He is a former Marine who served in the Vietnam War and a recovering alcoholic, being a year sober.

Analysis of blood levels of inorganic compounds in the supplement indicated the selenium concentrations were 10 to 15 times higher than normal in the blood samples and 15 to 20 times higher than normal in the liver samples. Selenium was later confirmed to be the toxic factor. [142]
When fictional television anchor Howard Beale leaned out of the window, chanting, "I'm mad as hell, and I'm not going to take it anymore!" in the 1976 movie 'Network,' he struck a chord with ...
But sundowning has some unique signs that make it stand out from just being tired. “Fatigue can occur at all times of the day. Sundowning is truly confusion,” Dr. Kobylarz says.
The isotope selenium-75 has radiopharmaceutical uses. For example, it is used in high-dose-rate endorectal brachytherapy, as an alternative to iridium-192. [8]In paleobiogeochemistry, the ratio in amount of selenium-82 to selenium-76 (i.e, the value of δ 82/76 Se) can be used to track down the redox conditions on Earth during the Neoproterozoic era in order to gain a deeper understanding of ...
Chelation therapy is a medical procedure that involves the administration of chelating agents to remove heavy metals from the body. [1] Chelation therapy has a long history of use in clinical toxicology [2] and remains in use for some very specific medical treatments, although it is administered under very careful medical supervision due to various inherent risks, including the mobilization of ...
