Nosocomial diseases are mainly caused by two common pathogens, Escherichia coli and Staphylococcus aureus, which are becoming more and more resistant to conventional antibiotics. Therefore, it is becoming increasingly necessary to find other alternative treatments than commonly utilized drugs. A promising strategy is to use nanomaterials such as selenium nanoparticles. However, the ability to p...

Selenium (Se) is an essential element with a small difference between physiological and toxic doses. To provide more effective and safe Se dosing regimens, as compared to dosing with ionic selenium, nanoparticle formulations have been developed. However, due to the nano-formulation, unexpected toxic effects may occur. We used metabolite pattern determination in urine to investigate biological a...

Selenium is an important element for human's health, small size is very helpful for Se nanoparticles to be absorbed by human's body. Here, we present a facile approach to fabrication of small selenium nanoparticles (Nano-Se) as well as nanorods by dissolving sodium selenite (Na2SeO3) in glycerin and using glucose as the reduction agent. The as-prepared selenium nanoparticles have been character...

1 2 In this study, the hydrothermal carbonation of calcium hydroxide under high CO 2-Ar pressure 3 (90 bar) and high temperature (90 °C) coupled with a complex selenocystine fragmentation 4 was carried out by using a batch system in order to synthesize an elemental selenium 5 (Se 0)/calcite composite. Under O 2-poor conditions, the composite was mainly characterized 6 by red spherical selenium ...

Objective- This study aimed at evaluation of histopathological findings of application of chitosan- nano selenium biodegradable film on full thickness excisional wound healing in rats. Design- Experimental Study Animals- Seventy-two male Wistar rats Procedures- Animals were randomized into six groups of 12 animals each. Group I: Animals with created wounds and no...

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...

Improving human health is the considered major concern in area of medical and agricultural sciences. It achieved by providing good supplements with balanced diet to people forms cost effective safe nano-biofortified or nano-bioengineered vegetable crop plants fight against malnutrition other various diseases. And these nano-based methodologies are involved use nanoparticles essential nutrients ...

Precise structural studies of nano-crystalline minerals using diffraction techniques have been hindered by the broad diffraction peaks found in their diffraction patterns. In this thesis, I have applied molecular scale techniques such as High-Energy X-ray Diffraction and Molecular Dynamics simulations to study the structure and reactivity of two nano-minerals of important environmental signific...

Selenium nanoparticles (SeNPs) are the object of great interest due to their potential be used in many areas industry and medicine. Work is still underway on synthesis methods; however, green methodologies becoming more popular. In this study, aqueous extracts black tea as well infusions popular herbs such chamomile mint were SeNPs serving Se(IV) reducers its nano form. The influence reagents c...
