Abstract In recent years, the importance of nanomaterials in food science, medicine, etc. has been increasing quickly. Herein, organic and inorganic red selenium nanoparticles synthesised by reduction sodium selenite with chemical biological reducing agents. Grey hexagonal form aqueous powder was assembled at a high temperature 85 °C for 10 min. Also, enriched yogurt made that contained about 2...

The article reviews the progress in basic research of selenium and cancer prevention during the past decade. Special emphasis is placed on the following four major areas of discussion: 1) chemical forms of selenium and anticarcinogenic activity; 2) selenium-enriched food; 3) in vitro effects of selenite vs. monomethylated selenium; and 4) aromatic selenium compounds. It is clear that basic rese...

The weathering of selenium-rich rocks or anthropogenic activities such as mining smelting can release selenium into the environment, posing a significant environmental risk. increased monitoring and enforcement regulations have resulted in protocols to efficiently measure treat water effluent water. principal aqueous forms inorganic are selenite (Se(IV)) selenate (Se(VI)). Selenate, due its oxy...

Abstract The supplementation of Selenium-enriched probiotics is effective in reducing oxidative stress and maintaining meat quality stability broiler chicken especially under heat stress. An experimental study was conducted to perform Comparative analysis Selenium yeast with inorganic Se broilers A total 120 chicks one day were assigned 4 groups each consisting 30 fed on same basal diet but dif...

Mercury is one of the most toxic substances known to humans. It has been introduced into the human environment and has also been widely used in medicine. Since circumstantial evidence exists that the pathology of Alzheimer's disease (AD) might be in part caused or exacerbated by inorganic mercury, we conducted a systematic review using a comprehensive search strategy. Studies were screened acco...

Involvement of the bacterial thiopurine methyltransferase (bTPMT) in natural selenium methylation by freshwater was investigated. A freshwater environment that had no known selenium contamination but exhibited reproducible emission of dimethyl selenide (DMSe) or dimethyl diselenide (DMDSe) when it was supplemented with an organic form of selenium [(methyl)selenocysteine] or an inorganic form of...

Selenium is an essential element known to take part in human antioxidative defense and to protect against cardiovascular diseases and cancer. Consequently, supplementation of the diet with this element is necessary in order to achieve the protective effect. Several allium plants, radish etc have demonstrated the ability to preconcentrate and biotransform inorganic selenium into selenoaminoacids...

This paper presents results of the determination of the total concentration of arsenic, antimony and selenium and their inorganic speciation forms in water samples from grate ashes dumping grounds. Determined concentrations of elements were up to 128.8 ng/mL for arsenic, 153.7 ng/mL for antimony and 52.9 ng/mL for selenium, at the detection limits of 0.16 ng/mL for As, 0.18 ng/mL for Sb and 0.1...
