Presently, the regulatory mechanisms of selenium on human health, especially the regulatory mechanisms of selenium on human intestinal (gut) microflora and its effects on diseases are receiving attention from …

3. Thyroid Function and Selenium Status. The second essential trace element for the TH system, selenium, was discovered by the Swedish chemist J.J. Berzelius in 1817 . The human body contains around 14 mg of Se. The recommended intake is 150–200 µg/d and the no adverse effect level (NOAEL) for human uptake is 800 µg/d.

As an essential nutrient and trace element, selenium is required for living organisms and its beneficial roles in human health have been well recognized. The role …

Trace elements, such as iodine and selenium (Se), are vital to human health and play an essential role in metabolism. They are also important to thyroid metabolism and function, and correlate with thyroid autoimmunity and tumors. Other minerals such as iron (Ir), lithium (Li), copper (Co), zinc (Zn), manganese (Mn), …

The trace elements include more than 60 substances that are usually present in low concentrations in the environment and mammalian tissues. They are generally present in tissue and serum in picogram or microgram amounts, and their absorption, distribution, storage and excretion are tightly controlled. ... Selenium is present in …

Important physiological functions in human metabolism are known for nine trace elements: selenium, zinc, copper, manganese, chromium, iron, molybdenum, iodine and fluoride. Lack of, or an ...

However, the role of selenium and other trace elements is still controversial, and the recent available reviews on the topic are either missing or out-of-date. We carried out an updated systematic review and meta-analysis, in which we summarized the results of case-control studies reporting levels of selenium, copper, iron, and zinc in …

There are about 70 trace elements that account for 0.01% -0.005 wt% of human body weight, including iron, copper, manganese, zinc, cobalt, molybdenum, chromium, nickel, vanadiumfluorine, selenium, iodine, silicon, tin and so on.(1) Although they are present in living body in small amounts, they are important for the growth, …

Selenium (Se) is an essential trace element in humans 1,2. Selenium is generally taken up from the diet through food or other forms of external supplementation. Dietary selenium is obtained in the ...

4 Trace Elements 101 Chemists review selenium data. Evidence is limited as to whether intakes of selenium greater than the amount needed to allow full expression of …

Icahn School of Medicine at Mount Sinai: "Selenium." Journal of Trace Elements in Medicine and Biology: "Acute human toxicity and mortality after selenium ingestion: A review."

Selenium, a trace element, is important in the diet and health of both plants and animals, but can be only taken in very small amounts. Exposure to an excess amount of selenium is known to be toxic and causes health problems. With an upper intake level of 400 micrograms per day that can be tolerated, too much selenium can lead to selenosis …

Selenium, an important trace element, is required for selenoprotein synthesis and acts crucially for proper growth and skeletal development. However, the intake of an optimum amount of selenium is critical, as both selenium deficiency and toxicity are hazardous for health. In this review, we have systematically analyzed the existing …

Trace elements such as boron and selenium have anti-inflammatory and antioxidant effects, increasing cartilage matrix formation and enhancing chondrocyte proliferation, resulting in preventing and treating OA. However, excessive or insufficient trace elements like copper are risk factors for osteoarthritis. TABLE 1.

In the following chapter, the essential trace element selenium (Se) will be viewed foremost from the nutritional perspective. For this reason, a more general consideration of the relevant target group of subjects is needed, which explains why the title includes the word "beyond" the focus of Se in thyroid disease as well as the brackets …

11. Selenium (se) Selenium is a vital trace element which is an essential component of antioxidant enzymes. Selenium salts are required for several cellular functions in the human body but their …

Selenium (Se), a trace element, has evolved from its toxic properties to an essential element. Se was known a potent antioxidant through glutathione peroxidase (selenium being part of this molecule). Later, many other selenium-binding proteins were discovered and their functions were tried to be known with unsuccessful results in many cases. Se ...

A small number of trace elements, such as selenium, are neither metals nor radionuclides. Selenium occurs naturally in sedimentary rocks, shales, coal and phosphate deposits, and soils. Application of irrigation water, which contains dissolved oxygen, can caused selenium to be released from sediment into groundwater, particularly in arid areas.

In addition to iodine and selenium, also other trace elements such as iron, zinc, and copper are needed for proper thyroid function. Iron deficiency, the most common global trace element deficiency, adversely affects heme-containing thyroperoxidase (TPO), which catalyses initial steps of TH synthesis [20,21,22]. Zinc serves as a co-factor for ...

Selenium (Se) is an essential trace element for humans and animals. Its necessity for plants is still under examination.
