Oxidative stress and iron accumulation are tightly associated with neurodegenerative diseases. Mitochondrial ferritin (FtMt) is identified as an iron-storage protein located in the mitochondria, and its role in regulation of iron hemeostasis in neurodegenerative diseases has been reported. However, the role of FtMt in hydrogen peroxide (H2O2)-induced oxidative stress and iron accumulation in ne...

hydrogen donor: oxygen oxidoreductase (í µí»¼-methene hydroxylating, decycliz-ing)) catalyzes the rate limiting the step in the oxidative catabolism of heme to generate biliverdin-IXí µí»¼, which is subsequently converted to bilirubin-IXí µí»¼ by cytosolic NAD(P)H-dependent biliverdin reductase [1]. This reaction, which requires molecular oxygen as well as electrons from NADPH-dependent cytochr...

background: today the use of natural substances plays a major role in improving the growth and immunity of aquatic organisms. objectives: the purpose of the present study was to evaluate the effects of iron nanoparticles with lactobacillus casei as a probiotic on growth parameters and probiotic counts in rainbow trout intestine. methods: seven hundred and twenty fish with 12±0.49 g initial weig...

Iron oxide nanoparticles with unique magnetic properties have a high potential for use in several biomedical, bioengineering and in vivo applications, including tissue repair, magnetic resonance imaging, immunoassay, drug delivery, detoxification of biologic fluids, cell sorting, and hyperthermia. Although various surface modifications are being done for making these nonbiodegradable nanopartic...

The field of research on ferroptosis has seen an explosive growth in the past few years since term was coined 2012. This review highlights current state knowledge developmental mechanism this unique mode cell death, induced by iron-dependent phospholipid peroxidation, which is regulated a variety cellular metabolic events, including redox homeostasis. xCT system, amino acid antiporter that supp...

Superparamagnetic iron oxide nanoparticles (SPIONs) as a contrast agent have been widely used in magnetic resonance imaging for tumor diagnosis and theranostics. However, there has been safety concern of SPIONs with cirrhosis related to excess iron-induced oxidative stress. In this study, the impact of iron overload by SPIONs was assessed on a mouse cirrhosis model. A single dose of SPION injec...

Oxidative stress plays an important role in the degeneration of dopaminergic neurons in Parkinson's disease (PD). Disruptions in the physiologic maintenance of the redox potential in neurons interfere with several biological processes, ultimately leading to cell death. Evidence has been developed for oxidative and nitrative damage to key cellular components in the PD substantia nigra. A number ...

This study was undertaken to address the current deficient knowledge of cellular response to nanosized particle exposure. The study evaluated the acute toxic effects of metal/metal oxide nanoparticles proposed for future use in industrial production methods using the in vitro rat liver derived cell line (BRL 3A). Different sizes of nanoparticles such as silver (Ag; 15, 100 nm), molybdenum (MoO(...

Engineered iron nanoparticles, with sizes smaller than 100 nm, have been of high concern because of their promising capability in environmental remediation. Nanoparticles based on zero-valent iron (nZVI) have the potential not only to migrate in the environment and interact with pollutants but also influence the living organisms by direct impact or by changes of groundwater parameters. The basi...

The data presented in this article are related to the research article "Intramyocardial Fate and Effect of Iron Nanoparticles co-injected with MACS® purified Stem Cell Products" (Müller et al., 2017) [1]. This article complements the cellular localization of superparamagnetic iron dextran particles (MACS® MicroBeads) used for magnetic activated cell sorting (MACS®). Data evaluate the time-depen...
