Four different canine mammary tumor (CMT) cell lines and a nonneo plastic primary culture of mammary cells were examined for their in vitro responsiveness to selenium supplementation. These cell lines were found to vary in their metabolic response to increasing concentrations of selenium. Sensitivity to selenium, as sodium selenite, increased with increasing concentrations of this trace element...

The present study aims to explore how selenium supplementation affects the element distribution in the liver tissue of rats subjected to strenuous swimming exercise. Thirty-two Spraque-Dawley male rats were equally divided into the four groups: Group 1, normal control group. Group 2, selenium-supplemented, non-swimming (0.6 mg/kg/day sodium selenite) group. Group 3, swimming, no supplementation...

Pharmacokinetics Selenium levels in the body are largely dependent on the amount of the element in the diet. However, the form of selenium within the diet has an important influence on absorption. L-(+)selenomethionine is readily absorbed from the gastrointestinal tract and is significantly better absorbed and retained in the body than inorganic selenium in the form of selenite. L-(+)selenometh...

background selenium deficiency is a common problem in patients with chronic kidney disease (ckd). this micronutrient has anti-inflammatory and anti-oxidant effects. selenium is also found in high concentrations in the thyroid gland. objectives to determine the effect of selenium supplementation on thyroid function tests and acute phase reactants in hemodialysis patients. patients and methods in...

The goal of the experiment was to compare the effect of supplementation of inorganic and the new organically bound (lactate-protein selenium complex) form of selenium (Se) in feed for goats. The 31 goats were split into three groups: control (C) without Se supplementation, AN group administered sodium selenite, ORG group administered lactate-protein selenium complex (Selene Chelate, Agrobac, Cz...

Selenium is an essential trace mineral that is required for many physiological functions in animals and the potential relevance of selenium to the reproductive system of livestock has been considered by many researchers. The objective of this study was to examine the effect of selenium supplementation on the spermatogenic cells of goat. Eight young male crossbred (Katjang x Boer) goats, aged be...

BACKGROUND Insulin-like growth factor-1(IGF-1) has a multitude of effects besides cell growth and metabolism. Reports also indicate anti-inflammatory and antioxidative effects. The concentrations of IGF-1 decrease with age and during inflammation. As selenium and coenzyme Q10 are involved in both the antioxidative defense and the inflammatory response, the present study aimed to examine the eff...

Selenium is an essential mineral naturally found in soil, water, and some of the food. As an antioxidant, it is one of the necessary trace elements in human body and has been suggested as a dietary supplement for health benefit. Although the human body only needs a trace amount of selenium every day, plenty of recent studies have revealed that selenium is indispensable for maintaining normal fu...

The impact of providing selenomethionine (2.7 mumol Se) or selenium-enriched yeast (2.9 mumol Se) on the selenium status of lactating and nonlactating women with customary intakes of approximately 1.3 mumol Se/d was studied. Plasma selenium declined in unsupplemented lactating women but not in nonlactating women. Selenomethionine increased plasma selenium in both lactating and nonlactating wome...

Commercially available calf serum did not supply the cultured murine fibroblast cell line L929 with amounts of selenium and alpha-tocopherol sufficient to protect against peroxide damage. Supplementation of the culture medium with 30 microM alpha-tocopherol or 50 nM sodium selenite led to a substantial increase of cellular alpha-tocopherol concentrations from 18 +/- 3.0 to 3179 +/- 93.0 pmol/10...
