Iron assimilation storage in prokaryotes

Storage Iron Metabolism

Iron is an essential element for the living body. The human body stores iron mostly in liver, spleen, marrow and skeletal muscle in the form of ferritin and hemosiderin. Hemosiderin has been known as yellowish granules that can be stained by Prussian blue in the tissue cells. On the other hand, ferritin is invisible by photomicroscopy or may be faintly visible and stained diffusely in the tissu...

Assimilation of marine extracellular polymeric substances by deep-sea prokaryotes in the NW Mediterranean Sea.

This study examined total uptake of extracellular polymeric substances (EPS) and glucose and the percentage of prokaryotic cells (Bacteria, Crenarchaea and Euryarchaea) consuming these compounds in the major water masses at the DYFAMED site (NW Mediterranean Sea). The potential assimilation rates of EPS at 10 m depth were higher but on the same order of magnitude as those at 2000 m depth (from ...

Liver iron concentration, stainable iron, and total body storage iron.

Liver iron concentration has been determined chemically in 154 liver biopsies and the findings compared with the routine histological assessment of stainable parenchymal iron, performed by an independent observer. There was a significant correlation between liver iron concentration and histochemical grading but the relationship did not have a normal linear form. Absence of stainable iron corres...

The Rate of Iron Accumulation in Iron Storage Disease.

MR characterization of hepatic storage iron in transfusional iron overload.

PURPOSE To quantify the two principal forms of hepatic storage iron, diffuse, soluble iron (primarily ferritin), and aggregated, insoluble iron (primarily hemosiderin) using a new MRI method in patients with transfusional iron overload. MATERIALS AND METHODS Six healthy volunteers and 20 patients with transfusion-dependent thalassemia syndromes and iron overload were examined. Ferritin- and h...
