Colorectal cancer (CRC) is a major cause of mortality throughout the world and risk of CRC is known to be modulated by nutritional factors. Low intake of the micronutrient selenium (Se) has been implicated as a risk factor in CRC, and in this article we describe the biochemical functions of selenium in selenoproteins, review the evidence for an association of selenium status with CRC and adenom...

an experiment was conducted in order to evaluate the effects of se spraying on yield and growth indices of wheat under drought stress condition, in agriculture and natural resource research center of tehran province in 2011-12. a split plot layout within randomized complete block design with three replications were used. main plots were three irrigation treatments (normal irrigation, non-irriga...

BACKGROUND The New Zealand population has both marginal selenium status and mild iodine deficiency. Adequate intakes of iodine and selenium are required for optimal thyroid function. OBJECTIVE The aim of the study was to determine whether low selenium and iodine status compromises thyroid function in an older New Zealand population. DESIGN We investigated the effects of selenium and iodine ...

Fertility is one of the most important parameters in breeder farms and cockerels play an outstanding role in fertility of eggs in broiler breeder units. Todays, supplementation of feed-additives such as organic selenium is used to increase fertility. The aim of this study was to evaluate the effects of different levels of Nano-Selenium (Nano-Se) on expression of molecular markers of spermatogon...

The effect of selenium supplementation in inorganic and organic form was investigated in three five-member groups of ewes and their lambs in the course of 7 months. The basal feed ration contained 55 μg Se, ewes of experimental group E1 received a supplement of 180 μg Se in sodium selenite, and ewes of experimental group E2 were applied a supplement of 180 μg selenium bound in the biomass of th...

Considering the review by Puspitasari and colleagues, an additional discussion of the endpoints of the Se supplementation studies described would be helpful. In our view, selenium can safely be given to selenium-deficient cancer patients prior to and during radiotherapy. Therefore, in order to help the radiation oncologist in decision making, we strongly advocate to determine the selenium statu...

BACKGROUND Selenium (Se) is an essential trace element in living systems. Microorganisms play a pivotal role in the selenium cycle both in life and in environment. Different bacterial strains are able to reduce Se(IV) (selenite) and (or) Se(VI) (selenate) to less toxic Se(0) with the formation of Se nanoparticles (SeNPs). The biogenic SeNPs have exhibited promising application prospects in medi...

This study was conducted to determine the effects of vitamin E selenium ( Na2-SeO3) and organic selenium (Sel-Plex) on performance of broiler reared under chronic heat stress during summer season (30.043.5°C). A total of 180 one-day-old broiler chicks were randomly assigned to three selenium treatments, and two stocking density with two replicates of 15 birds each. The birds with a 3 x 2 factor...
