Exploring the role of quantitative susceptibility mapping in assessing brain iron deposition in hemodialysis patients [PDF]

Insights into Imaging
Patients with end-stage renal disease (ESRD) develop brain iron deposition due to iron metabolism disorders induced by long-term hemodialysis. This abnormal iron accumulation accelerates cognitive impairment (CI) and neurodegenerative pathologies ...

Corroded iron stent increases fibrin deposition and promotes endothelialization after stenting

Bioengineering & Translational Medicine, 2023
Poststent restenosis is caused by insufficient endothelialization and is one of the most serious clinical complications of stenting. We observed a rapid endothelialization rate and increased fibrin deposition on the surfaces of the corroded iron stents ...

Spatial-temporal changes of iron deposition and iron metabolism after traumatic brain injury in mice

Frontiers in Molecular Neuroscience, 2022
Excessive iron released by hemoglobin and necrotic tissues is the predominant factor that aggravates the outcome of traumatic brain injury (TBI). Regulating the levels of iron and its metabolism is a feasible way to alleviate damage due to TBI.

Iron deposition is associated with motor and non-motor network breakdown in parkinsonism [PDF]

Frontiers in Aging Neuroscience
BackgroundIron deposition has been observed in Parkinsonism and is emerging as a diagnostic marker for movement disorders. Brain functional network disruption has also been detected in parkinsonism, and is believed to be accountable for specific symptoms

In newly diagnosed diabetes, hyperglycemia is associated with increased brain iron deposition, measured by MRI-based Quantitative Susceptibility Mapping (QSM) [PDF]

Journal of Advanced Research
Background: Long-term Type 2 diabetes mellitus (T2DM) affects multiple organs and systems throughout the body, including the cardiovascular, renal, and nervous systems. In the brain, T2DM impacts brain function, leading to cognitive impairment.

Cerebral Iron Deposition in Neurodegeneration

Biomolecules, 2022
Disruption of cerebral iron regulation appears to have a role in aging and in the pathogenesis of various neurodegenerative disorders. Possible unfavorable impacts of iron accumulation include reactive oxygen species generation, induction of ferroptosis, and acceleration of inflammatory changes.
