Recent studies have shown that elemental selenium particles at nano-size (Nano-Se) exhibited comparable bioavailability and less toxicity in mice and rats when compared to sodium selenite, selenomethinine and methylselenocysteine. However, little is known about the toxicity profile of Nano-Se in aquatic animals. In the present study, toxicities of Nano-Se and selenite in selenium-sufficient Med...

in this study, selenium was recovered from an industrial dust. after the purification process, the researchers were able to prepare selenium micro powder. the objective of this study was to prepare selenium nano particles by water solution phase method from the micro powders. the results showed that selenium micronized powder and nano particles had high purity. the obtained nanoparticles were t...

The fisheries and livestock sectors capture the highest share of protein-rich animal food and demonstrate accelerated growth as an agriculture subsidiary. Environmental pollution, climate change, as well as pathogenic invasions exert increasing stress impacts that lead the productivity momentum at a crossroads. Oxidative stress is the most common form of stress phenomenon responsible for the re...

BACKGROUND AND AIM Nanoparticles can bypass conventional physiological ways of nutrient distribution and transport across tissue and cell membranes, as well as protect compounds against destruction prior to reaching their targets. In ovo administration of nanoparticles, may be seen as a new method of nano-nutrition, providing embryos with an additional quantity of nutrients. The aim of the stud...

Honey is an excellent source of polyphenolic compounds that are effective in attenuating quorum sensing (QS), a chemical process of cell-to-cell communication system used by the opportunistic pathogen Pseudomonas aeruginosa to regulate virulence and biofilm formation. However, lower water solubility and inadequate bioavailability remains major concerns of these therapeutic polyphenols. Its ther...

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...

528 nature nanotechnology | VOL 3 | SEPTEMBER 2008 | www.nature.com/naturenanotechnology Interestingly, the nano-selenium material captured five times more mercury than the maximum predicted on the basis of its surface area, indicating significant penetration of mercury into the nanoselenium matrix. This did not occur in the other sorbent materials. Even so, the amount of mercury sequestered wa...
