Selenium, selenoproteins and neurodegenerative diseases.
It is unsurprising that our understanding of the role of selenium in neurological function is somewhat immature, considering its relatively recent discovery as an essential element to human health. Selenocysteine, the 21st amino acid, is the defining feature of the 25 selenoprotein-encoding genes so far discovered within the human genome. The low abundance of these proteins in the brain belies ...
متن کاملSelenium and selenoproteins in health and disease.
The beneficial role of the trace element selenium (Se) in human health has been known for several decades and is attributed both to low-molecular-weight Se compounds and to its presence within 25 selenoproteins in the form of the amino acid selenocysteine (Sec). Incorporation of Sec into selenoproteins involves decoding of the UGA codon. This process requires multiple features, such as the Sec-...
متن کاملSelenium, selenoproteins and human health: a review.
Selenium is of fundamental importance to human health. It is an essential component of several major metabolic pathways, including thyroid hormone metabolism, antioxidant defence systems, and immune function. The decline in blood selenium concentration in the UK and other European Union countries has therefore several potential public health implications, particularly in relation to the chronic...
متن کاملTrace Element Analyses (Zinc and Selenium) in Pediatric Malignant Lymphomas.
Ninetysix untreated patients with Malignant lymphoma's, 81 Hodgkin's disease and 15 Burkitt's lymphoma were studied for zinc (Zn) and selenium (Se) status. Plasma and hair Zn, and Se levels were measured by atomic absorption spectrophotometry. Chronic Zn and Se deficiencies (low plasma and low hair Zn and Se levels together) were found to be associated with Malignant lymphoma's in Turkish child...
متن کاملUltra Trace Elements and Selenium
During the past decade there has been a large upsurge in interest in nutritionally essential trace elements. In the clinical field the recognition that deficiency can occur in human subjects in many practical dietary situations has been of crucial importance from the public health viewpoint worldwide. In this chapter we review briefly our knowledge of the ultra trace elements chromium, manganes...
