Nanoparticles from natural and anthropogenic sources are abundant in the environment,
thus human exposure to nanoparticles is inevitable. Due to this constant exposure, it is …

Nanosilver, due to its small particle size and enormous specific surface area, facilitates more
rapid dissolution of ions than the equivalent bulk material; potentially leading to increased …

Biologically formed nanoparticles of the strongly magnetic mineral, magnetite, were first
detected in the human brain over 20 y ago [Kirschvink JL, Kobayashi-Kirschvink A …

Multiple abnormalities occur in the homeostasis of essential endogenous brain biometals in
age-related neurodegenerative disorders, Alzheimer's disease, Parkinson's disease …

Airborne particulate matter poses a serious threat to human health. Exposure to nanosized
(< 0.1 μm), vehicle-derived particulates may be hazardous due to their bioreactivity, their …

Background The production of peroxide and superoxide is an inevitable consequence of
aerobic metabolism, and while these particular'reactive oxygen species'(ROSs) can exhibit a …

Background: Iron can catalyze damaging free radical reactions. With age, iron accumulates
in brain gray matter regions and may contribute to the risk of developing age-related …

While magnetic nanoparticles offer exciting possibilities for stem cell imaging or tissue
bioengineering, their long-term intracellular fate remains to be fully documented. Besides, it …

Iron deficiency anaemia is prevalent in older age, particularly after the age of 80. Serum
ferritin concentrations also decline, although there is no evidence to suggest that changes in …

Over recent years, advancements in nanomedicine have allowed new approaches to
diagnose and treat tumors. Nano drug delivery systems exploit the enhanced permeability …
