The effect of selenium intake on the development of pancreatic cancer was investigated in female Syrian golden hamsters. Four-week-old hamsters were divided into 2 groups according to the selenium level in their drinking water and were fed a purified diet containing less than 0.05 ppm selenium. Starting 4 weeks later, groups received 10 s.c. injections at weekly intervals of N'-nitrosobis(2-oxo...

BACKGROUND Selenium is an essential micronutrient known for its antioxidant function. However, the association of serum selenium with lipid profiles and fasting glucose are inconsistent in populations with average intake of selenium. Furthermore, there were few studies conducted specifically for the elderly. This study examined the relationship of serum selenium concentration with serum lipids ...

Recent findings have raised concern about possible associations of high selenium exposure with diabetes and hyperlipidemia in the US, a population with high selenium status. In the UK, a population with lower selenium status, there is little data on the association of selenium status with cardio-metabolic risk factors in the general population. We examined the association of plasma selenium con...

Fish contain methylmercury and the potentially protective element, selenium. Blood and brain concentrations of these elements were determined in female rats after consuming AIN-93-based diets containing 0.06 or 0.6 ppm of selenium (Se) and drinking water containing 0, 0.5, or 5 ppm of mercury as methylmercury (MeHg) for 6 or 18 months. Brain and blood concentrations of mercury and selenium were...

BACKGROUND Increased mortality from lymphoid malignancies following exposure to environmental selenium has recently been reported. Moreover, conflicting results have been found in investigations examining the relationship between serum concentrations of selenium and some clinical features of malignant lymphoproliferative diseases. METHODS Serum concentrations of selenium were analyzed by atom...

The influence of application of increasing doses of selenium (0.05 mg, 0.10 mg and 0.20 mg/kg) into soil in pot experiments, with NPK fertilization of spring wheat (Triticum aestivum L., variety Banti), on the biomass yield (grain, straw, roots) and on selenium accumulation was observed. Selenium in the form of sodium selenite (Na2SeO3·5H2O) and the NPK nutrients in the form of LAD-27, Ca(H2PO4...

Selenium is a trace element, essential in small amounts, but it can be toxic in larger amounts. Levels in the body are mainly dependent on the amount of selenium in the diet, which is a function of the selenium content of the soil. Humans and animals require selenium for normal functioning of more than about 30 known selenoproteins, of which approximately 15 have been purified to allow characte...

BACKGROUND Selenium may prevent colorectal cancer. However, several previous studies are small and few investigated the association between selenium and colorectal cancer among women whose selenium metabolism may differ from men. Furthermore, genetic variants in selenoenzymes may be associated with colorectal cancer risk. METHODS This nested case-control study investigated whether serum selen...

Title: EFFECT OF DIETARY SELENIUM STATUS ON T CELL IMMUNITY AND CANCER XENOGRAFT IN NUDE MICE Alexandra Holmstrom, Master of Science, 2010 Directed By: Assistant Professor Wen-Hsing Cheng, Department of Nutrition and Food Science Selenium (Se) is known to regulate carcinogenesis and immunity at nutritional and supranutritional levels. Because the immune system provides one of the main body defe...

Abstract—Selenium is an-antioxidant which is important for human health enters food chain through crops. In Kenya Zea mays is consumed by 96% of population hence is a cheap and convenient method to provide selenium to large number of population. Several soil factors are known to have antagonistic effects on selenium speciation hence the uptake by Zea mays. There are no studies in Kenya that has...
