Mobilization of selenium by a selenium-dependent bacterium
Biological Trace Element Research, 1990A selenium-dependent bacterium, Bacillus sp., failed to grow on selenium-free media. However, it is able to grow at high concentrations of sodium selenite containing media up to 3% (w/v). It accumulated extraordinary high quantities of selenium, 432 ppm/mL.

Metabolism of selenium in a selenium-dependent bacterium
Biological Trace Element Research, 1990A selenium-dependent Bacillus sp. is able to grow well up to 3% sodium selenite-containing media. The bacterium completely failed to grow on media devoid of selenium. The presence of selenium in the growth media increased the bacterial contents of proteins, carbohydrates, and lipids.

BioFactors, 1999
Selenium deficiency has long been known to be associated with decreased male and female fertility in live stock. The underlying mechanisms may be numerous. As far as female fertility is concerned, impairment of fertilization of ova of selenium-deficient cows and sheep, retained placenta in cows, and the mastitis metritis agalactia complex in pigs are ...

Blood and its main components are commonly used to detect states of selenium deficiency. In order to examine whether human platelets are able to provide better or additional information, improvements of the analytical method resulted in surprisingly narrow normal ranges for selenium and other mineral elements using neutron activation analysis (NAA) and

Inadequate supply of the essential trace element selenium (Se) has been associated with predisposition for, or manifestation of, various human diseases such as Keshan and Kashin-Beck disease, cancer, impaired immune function, neurodegenerative and age-related disorders and disturbances of the thyroid hormone axis.

Annual Review of Biochemistry, 1990
The toxicity of selenium to animals and plants has been known and extensively documented since the 1930's, but it is only during the past 15 years that selenium has also been shown to be an essential micronutrient for animals and bacteria. Very little is known about the specific role or roles of selenium and, to date, there are only three enzyme ...

Selenium occurs as inorganic selenite or selenate and in organic forms in plants and other organisms used for food. The human selenoproteome consists of 25 selenoproteins. The main groups are glutathione peroxidases 1-5, iodothyronine deiodinases 1-3, thioredoxin reductases, selenoprotein P (SelP), and other proteins mostly with unknown function.

Selenium intake and serum selenium in Finland: effects of soil fertilization with selenium
The American Journal of Clinical Nutrition, 1988Since fall 1984 all agricultural multinutrient fertilizers in Finland have been supplemented with sodium selenate in an attempt to improve the nutritional quality of local foodstuffs known to be exceptionally low in selenium. The intervention has been effective from the growing season 1985 and it has affected practically all domestic agricultural ...

Selenium and nano-selenium in agroecosystems
Environmental Chemistry Letters, 2014Selenium (Se) is an essential health element becoming rare in food as a result of intensive plant pro- duction. Indeed, several enzymes contain selenium in the form of the unusual selenocysteine amino acid. Selenium was found an essential nutrient in the late 1950s, when selenium was found to replace vitamin E in the diets of rats and chicks for the ...

Psoriasis is a chronic, immune-mediated skin disease characterized by production of reactive oxygen species due to the activation of tumor necrosis factor alpha (TNF-α), which is thought to be an important factor in inducing and maintaining psoriatic lesions. As an external factor, ultraviolet B (UVB) radiation stimulates TNF-α production and secretion
