This study was conducted to investigate the effect of nano-selenium (nano-Se) on performance, meat quality, immune function, oxidation resistance, and tissue selenium content in broilers. A total of five hundred forty 1-d-old male Arbor Acres broilers were randomly allotted to 1 of 5 treatments with each treatment being applied to 6 replicates of 18 chicks. The 5 treatments consisted of corn-so...

The effect of two different doses (1 microg Se/Kg and 50 microg Se/Kg Body wt) of selenium on nicotine induced hyperlipidemia was investigated in rats. Results revealed that nicotine intake caused an increase in concentration of cholesterol, triglycerides, free fatty acids, phospholipids and low density lipoprotein compared to control group. Coadministration of selenium along with nicotine redu...

wide range of products is available; from inorganic, sodium selenite or selenate coated or not, even nanoparticles to organic forms such as selenized yeasts, chelates of selenium methionine (SeMet), pure forms of SeMet or hydroxy-selenomethionine, and some complexes sources of Se based on mixing mineral Se with glycinates, proteinates, etc. It has been confirmed that, comparing with mineral sel...

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...

Certain anaerobic bacteria respire toxic selenium oxyanions and in doing so produce extracellular accumulations of elemental selenium [Se(0)]. We examined three physiologically and phylogenetically diverse species of selenate- and selenite-respiring bacteria, Sulfurospirillum barnesii, Bacillus selenitireducens, and Selenihalanaerobacter shriftii, for the occurrence of this phenomenon. When gro...

BACKGROUND Microorganisms that are exposed to pollutants in the environment, such as metals/metalloids, have a remarkable ability to fight the metal stress by various mechanisms. These metal-microbe interactions have already found an important role in biotechnological applications. It is only recently that microorganisms have been explored as potential biofactories for synthesis of metal/metall...

To investigate whether selenium (Se) accumulation in plants provides a chemical defense against generalist insect herbivores, the feeding preference and performance of a mix of orthopteran species were investigated. The selenium hyperaccumulator Stanleya pinnata and accumulator Brassica juncea were used in herbivory studies in the laboratory, and S. pinnata was also used in a manipulative field...

In fi eld experiments, tartary buckwheat and hybrid buckwheat were foliarly sprayed with an aqueous solution of sodium selenate (20 mg Se L–1). In treated plants, the selenium content was signifi cantly higher than in controls, irrespective of the plant part and taxon of buckwheat. The highest average Se concentrations in hybrid and tartary buckwheat were found in seeds. The main Se species fou...

PREMISE OF THE STUDY Are there dimensions of symbiotic root interactions that are overlooked because plant mineral nutrition is the foundation and, perhaps too often, the sole explanation through which we view these relationships? In this paper we investigate how the root nodule symbiosis in selenium (Se) hyperaccumulator and nonaccumulator Astragalus species influences plant selenium (Se) accu...

Background:  The development of nanotechnology has been a boon to mankind as its significance paved the way for several applications in therapeutics. This study was to evaluate the anti-arthritic capability of nano Selenium-lovastatin mixture (Lov-Se) against inflammatory cascade in arthritic irradiated rats. Materials and Methods: Animal model of Arthritis was organized by subcutaneous in...
