Analysis of Potential Iron Toxicity in Hemodialysis Patients Under Intravenous Iron Treatment

Medical Sciences
Background/Objectives: Higher iron doses are used in the anemia treatment of hemodialysis patients, which allows for lower doses of erythropoiesis-stimulating agents; however, there are concerns regarding the risk of iron toxicity.

Iron Deposition

Transactions of The Electrochemical Society, 1941
There are very limited applications of iron plating today. On the other hand, electro forming with iron and electrowinning of iron have recently met with renewed interest. Detailed instructions for operating the iron sulfate and the iron chloride baths are presented.

Gastric siderosis: An under-recognized and rare clinical entity

SAGE Open Medicine, 2016
The increased deposition of iron in gastric mucosa is known as gastric siderosis. It is believed that the only regulated step of the iron metabolism cycle occurs during absorption in the small intestine. Once this system becomes overwhelmed due to either

Evaluation of Iron Overload Between Age Groups Using Magnetic Resonance Imaging and Its Correlation with Iron Profile in Transfusion-dependent Thalassemia

Acta Medica Indonesiana, 2018
Background: routine blood transfusion in transfusion-dependent-thalassemia (TDT) causes iron accumulation in various organ. Serum markers of iron overload, serum ferritin and transferrin saturation, are sensitive but not specific.

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Effects of dust deposition on iron cycle in the surface Mediterranean Sea: results from a mesocosm seeding experiment [PDF]

Biogeosciences, 2010
Soil dust deposition is recognized as a major source of iron to the open ocean at global and regional scales. However, the processes that control the speciation and cycle of iron in the surface ocean after dust deposition are poorly documented mainly due

Quantitative susceptibility mapping and blood neurofilament light chain differentiate between parkinsonian disorders

Frontiers in Aging Neuroscience, 2022
ObjectivesWe employed quantitative susceptibility mapping (QSM) to assess iron deposition in parkinsonian disorders and explored whether combining QSM values and neurofilament light (NfL) chain levels can improve the accuracy of distinguishing Parkinson ...
