Disruption of the mitochondrial network in a mouse model of Huntington's disease visualized by in-tissue multiscale 3D electron microscopy.

Huntington's disease (HD) is an inherited neurodegenerative disorder caused by an expanded CAG repeat in the coding sequence of huntingtin protein. Initially, it predominantly affects medium-sized spiny neurons (MSSNs) of the corpus striatum. No effective treatment is still available, thus urging the identification of potential therapeutic targets.

Genotoxicity and heating Performance of VFeO nanoparticles in Health applications.

The applications of magnetic nanoparticles (MNPs) as biocatalysts in different biomedical areas have been evolved very recently. One of the main challenges in this field is to design affective MNPs surfaces with catalytically active atomic centres, while producing minimal toxicological side effects on the hosting cell or tissues. MNPs of vanadium spinel ferrite (VFeO) are a promising material for mimicking the action of natural enzymes in degrading harmful substrates due to the presence of active V centres.

Observation of magnetic vortex configuration in non-stoichiometric FeO nanospheres.

Theoretical and micromagnetic simulation studies of magnetic nanospheres with vortex configurations suggest that such nanostructured materials have technological advantages over conventional nanosystems for applications based on high-power-rate absorption and subsequent emission. However, full experimental evidence of magnetic vortex configurations in spheres of submicrometer size is still lacking. Here, we report the microwave irradiation fabrication of FeO nanospheres and establish their magnetic vortex configuration based on experimental results, theoretical analysis, and micromagnetic simulations.

Direct Polyphenol Attachment on the Surfaces of Magnetite Nanoparticles, Using , , or .

This study presents an alternative approach to directly synthesizing magnetite nanoparticles (MNPs) in the presence of , , and derived from natural sources (grapes, blueberries, and pomegranates, respectively). A modified co-precipitation method that combines phytochemical techniques was developed to produce semispherical MNPs that range in size from 7.7 to 8.
