aims: anemia occurs for different reasons. however the iron deficiency anemia (ida) is one of the most prevalent causes of anemia in all human communities. the goal of the present study was to assess the effect of serum ferritin deficiency on anemia in medical students. materials & methods: this cross-sectional study was conducted on students of kashan university of medical sciences in all educ...
Iron is an essential element for the functioning of cellular processes. Ferritins, major intracellular iron storage proteins, convert free Fe2+ into nontoxic Fe3+ which can be stored and transported where needed. To date, little known about metabolism in copepods; however, these crustaceans, ferritins have been used as biomarkers stress diapause. A limiting factor studies has use a single ferri...
Ferritins are iron storage proteins that overcome the problems of toxicity and poor bioavailability of iron by catalyzing iron oxidation and mineralization through the activity of a diiron ferroxidase site. Unlike in other ferritins, the oxidized di-Fe3+ site of Escherichia coli bacterioferritin (EcBFR) is stable and therefore does not function as a conduit for the transfer of Fe3+ into the sto...
Ferritins are ubiquitous proteins that oxidise and store iron within a protein shell to protect cells from oxidative damage. We have characterized the structure and function of a new member of the ferritin superfamily that is sequestered within an encapsulin capsid. We show that this encapsulated ferritin (EncFtn) has two main alpha helices, which assemble in a metal dependent manner to form a ...
Metallic nanoparticles have been increasingly suggested as prospective therapeutic nanoplatforms, yet their long-term fate and cellular processing in the body is poorly understood. Here we examined the role of an endogenous iron storage protein - namely the ferritin - in the remediation of biodegradable cobalt ferrite magnetic nanoparticles. Structural and elemental analysis of ferritins close ...
