An overview of molecular aspects of iron metabolism

open access: yes, 2006
Iron (Fe) is an essential, but potentially noxious, metal for almost all organisms. Its precise cellular regulation is necessary to ensure synthesis of numerous iron-containing proteins required for metabolic processes yet at the same time avoiding the ...

Ascorbate enhances iron uptake into intestinal cells through formation of a FeCl3-ascorbate complex [PDF]

open access: yes, 2010
It has been well documented that ascorbate enhances iron uptake, with a proposed mechanism based on reduction to the more absorbable ferrous form. We have performed a study on the effects of ascorbate on ferric iron uptake in the human epithelial Caco-

Iron and Iron Metabolism

open access: yesGüncel Pediatri, 2012
Iron is an essential element for almost all living organisms except some bacteria. A great number of new articles related to the iron metabolism have been published in recent years explaining new findings. Hepsidine, a peptide hormon, that is recently found, regulates iron methabolism by effecting iron absorbsion from gut, secreting iron from hepatic ...

Coagulative Granular Hydrogels with an Enzyme Catalyzed Fibrin Network for Endogenous Tissue Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...
