Selenium intake and serum selenium in Finland: effects of soil fertilization with selenium

The American Journal of Clinical Nutrition, 1988
Since 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 Biochemistry

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 in platelets

Biological Trace Element Research, 1988
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

Selenium and Psoriasis

Biological Trace Element Research, 2012
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

Contributions to the chemistry of selenium and selenium compounds—V the hydrolysis of selenium

Journal of Inorganic and Nuclear Chemistry, 1960
Abstract The reactions of selenium with water, with alkali hydroxides and with ammonium hydroxides were investigated. The reactions of selenium with alkali hydroxides and ammonium hydroxide afford colloidal selenium solutions. The experimental evidence was supported by theoretical considerations, on the basis of redox potentials.

Selenium and reproduction

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 ...

Selenium and nano-selenium in plant nutrition

Environmental Chemistry Letters, 2015
Selenium (Se) is a naturally occurring metalloid element which occurs nearly in all environments. Se is considered as a finite and non-renewable resource on the Earth. The common sources of Se in earth’s crust occur in association with sulfide minerals such as metal selenide, whereas it is rarely found in elemental form (Se0).
