The aim of this study was to investigate the interaction of cadmium chloride with mineral elements in rat nephrocytes in terms of the biosynthesis of nanocomplexes. The results show that selenium supplementation enhanced cadmium accumulation in kidneys. Analysis of the fluorescence revealed an increase in red fluorescence in the kidneys of rats co-exposed to cadmium and selenium. Interestingly,...

An overview highlighting the anti-cancer potential of (bio-essential) seleniumand tellurium-containing species, with an emphasis on biological targets and mechanisms of action, is presented. Studies thus far have focused on selenium(II) compounds (along with – to a lesser extent – inorganic selenium and selenium nanoparticles) which often successfully exploit the inherent anti-oxidizing ability...

Biogenic formation of nano-sized particles composed of various materials (in particular, selenium) by live microorganisms is widespread in nature. This phenomenon has been increasingly attracting the attention of researchers over the last decade not only owing to a range of diverse applications of such nanoparticles (NPs) in nanobiotechnology, but also because of the specificity of methodologie...

Introduction: Some factors such as exercise training and pharmacological interventions can slow tumor growth. To determine the underlying mechanisms, we investigated the effect of six weeks of interval exercise training along with ingestion on Bcl-2 and LC3 genes expression in the tumor tissue of breast tumor–bearing mice. Methods: Twelve female BALB/c mice were injected with cancer cell line a...

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...

The present experiment describes a synthesis process of composites based on graphene oxide, which was tested as a carrier for composites of metalor metalloid-based nanoparticles (Cu, Zn, Mn, Ag, AgP, Se) and subsequently examined as an antimicrobial agent for some bacterial strains (Staphylococcus aureus (S. aureus), methicillin-resistant Staphylococcus aureus (MRSA) and Escherichia coli (E. co...

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...

Selenium, a non-essential element for plants, is essential for animals as well as human beings. Although the role of selenium in plants is yet to be properly understood, previous researches have shown that this element can affect plant growth and metabolism. In this study, the effect of foliar application of selenium nanoparticles (0, 5, 10, and 20 mg/L) and sodium selenate (0, 5, 10, and 20 mg...

Abstract In recent years, the application of selenium nanoparticles has been increasing in medicine, agriculture, engineering, and food science. Therefore, researchers are converting inorganic sources into nano form by various methods. Particularly both probiotics pathogenic bacterial strains have ability to synthesize under aerobic anaerobic conditions. Amazingly, dose-dependent antibacterial ...

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 ...
