Selenium is an essential microelement required for a number of biological functions.
Selenium—and more specifically the amino acid selenocysteine—is present in at least 25 …

Nanotechnology is defined as the branch of science dealing with extremely small-sized
particles with a size in the range of 1–100 nm, which are termed nanoparticles. Due to the …

Selenium is a trace element essential to human health largely because of its incorporation
into selenoproteins that have a wide range of protective functions. Selenium has an ongoing …

Background With cancer cells encompassing consistently higher production of reactive
oxygen species (ROS) and with an induced antioxidant defense to counteract the increased …

Abstract Arsenic (As) and selenium (Se) are unusual metalloids as they both induce and
cure cancer. They both cause carcinogenesis, pathology, cytotoxicity, and genotoxicity in …

Oxidative stress is considered causal of aging and pathological cell death, however, very
little is known about its function in the natural processes that support the formation of an …

Emerging evidence suggests that dietary phytochemicals, in particular flavonoids, may exert
beneficial effects on the central nervous system by protecting neurons against stress …

Mitochondria were classically recognized as the organelles that produce the energy
required to drive the endergonic processes of cell life, but now they are considered as the …

Selenium is an essential dietary component for animals including humans, and there is
increasing evidence for the efficacy of certain forms of selenium as cancer-chemopreventive …

Molecular biology has recently contributed significantly to the recognition of selenium (Se) 2
