Background: Diffuse parenchymal liver diseases are contributing substantially to global morbidity and represent major causes of deaths worldwide. The aim our study is assess whether established hepatic fat iron quantitation relaxometry-based quantification hepatocyte-specific contrast material as surrogate for function estimation allows evaluate fibrosis.

UNLABELLED HFE-related hereditary hemochromatosis results in hepatic iron overload. Hepatocytes acquire transferrin-bound iron via transferrin receptor (Tfr) 1 and Tfr1-independent pathways (possibly Tfr2-mediated). In this study, the role of Hfe in the regulation of hepatic transferrin-bound iron uptake by these pathways was investigated using Hfe knockout mice. Iron and transferrin uptake by ...

In this attempt to forge a useful algorithm for the management of iron deficiency, it is prudent to have a discussion of the difference between overt iron deficiency, where the body iron stores are depleted, and functional iron deficiency, also known as iron restricted erythropoiesis, where ample iron is present, but unavailable. Prior to the discovery of hepcidin, the hepatic synthesized iron ...

The aim of the present study was to determine changes in body iron storage in adult dogs following phlebotomy. We performed repeated phlebotomies by removing 1% body weight (approximately 10% of the total blood volume) weekly for a total of 12 times using adult beagle dogs without an iron-restricted diet. After treatment, stored iron was decreased, as demonstrated by gradual reductions in serum...

Emerging clinical data indicate that transfusion-dependent patients with bone marrow-failure syndromes (BMFS) are at risk of the consequences of iron overload, including progressive damage to hepatic, endocrine, and cardiac organs. Despite the availability of deferoxamine (DFO) in Korea since 1998, data from patients with myelodysplastic syndromes, aplastic anemia, and other BMFS show significa...

As a principal aspect of their scavenging function, splenic and hepatic macrophages phagocytize and degrade senescent and damaged erythrocytes to recover iron, mainly for the production of hemoglobin in new erythrocytes but also for other carriers and enzymes requiring iron. Splenic red pulp macrophages are specialized for iron recycling with increased expression of proteins for the uptake of h...
