Introduction: Recent findings revealed the biological effects of iron oxide nanoparticles on the central nervous system. Moreover, the brain cholinergic system plays a role in the modulation of anxiety behaviors. Therefore, this study aimed to evaluate the role of dorsal hippocampal muscarinic cholinergic receptors of the CA1 area on anxiety induced by iron oxide nanoparticles in adult male rat...
Nanoparticles are being intensively investigated because of their unique optical, electrical and catalytic properties which make them a potential material for utilization in the field of medicine electronic and environmental issues. This paper is concerned with the removing a heavy metal, Chromium, from its aqueous solution by Iron oxide nanoparticle filtration. Solutions of varying chromium co...
We describe the synthesis and characterization of high-performance, superparamagnetic, iron oxide nanoparticle-based, heavy metal sorbents, which demonstrate excellent affinity for the separation of heavy metals in contaminated water systems (i.e., spiked Columbia River water). The magnetic nanoparticle sorbents were prepared from an easy-to-synthesize iron oxide precursor, followed by a simple...
In order to study the effect of zero-valent iron nanoparticles on morphological and physiological traits of canola (Brassica napus L. cv. 'Hayola 401') under salinity stress, a research was conducted under controlled conditions in factorial based on completely randomized design in three replicates. In the first phase, the zero-valent iron nanoparticles were synthesized and in the second phase, ...
background: despite the wide range of applications, there is a serious lack of information on the impact of the nanoparticles on human health and the environment. the present study was done to determine the range of dangerous concentrations of iron oxide nanoparticle and their effects on mouse embryonic stem cells. methods: iron oxide nanoparticles with less than 20 nanometers diameter were enc...
As the major iron storage protein, ferritin stores and releases iron for maintaining the balance of iron in fauna, flora, and bacteria. We present an investigation of the morphology and iron loading of ferritin (from equine spleen) using aberration-corrected high angle annular dark field scanning transmission electron microscopy. Atom counting method, with size selected Au clusters as mass stan...
in this study, a mixed matrix polyethersulfone/iron-nickel oxide nanoparticle nanofiltration membrane was prepared by the solution casting technique. polyvinylpyrrolidone was also used as a membrane pore former in membrane fabrication. the effect of iron-nickel oxide nanoparticles concentration in the casting solution on the membrane structure and performance was investigated. scanning optical ...
transfusion in the treatment of thalassemia gives rise to iron deposits in many organs. since there are many obstacles in the use of deferoxamin (dfo) as an iron chelating agent, it is important to find another alternative therapy that can act as iron chelation. the study aims to compare the histopathological pictures of the heart and spleen in iron-induced rats after administration of dfo and ...
Innate immune cells play a key role in the pathogenesis of multiple sclerosis and experimental autoimmune encephalomyelitis (EAE). Current clinical imaging is restricted to visualizing secondary effects of inflammation, such as gliosis and blood-brain barrier disruption. Advanced molecular imaging, such as iron oxide nanoparticle imaging, can allow direct imaging of cellular and molecular activ...
