Neutrophilic Iron-Depositing Microorganisms
2011Neutrophilic iron-depositing microorganisms include various groups of bacteria, algae, and protozoa. The most striking feature of these microorganisms is their ability to precipitate ferric iron around their cells and colonies in many different forms. Growth of these microorganisms has various practical implications, for example, formation of iron ore ...

MR imaging of iron depositional disease
Magnetic Resonance Imaging Clinics of North America, 2002This article discusses the physiology of iron metabolism in humans. The pathophysiology and MR imaging findings of disorders that result in iron deposition in the liver are described. Emphasis is placed on genetic, clinical, and imaging findings of hemochromatosis.

Abstract Iron ore deposits are widespread throughout the Circum Pacific (Park, 1972). However significant production has been confined to three areas: the south-east China province from Hainan island through Kwangtung and Fukien, the Malay Peninsula and the Philippines (Fig. 9.1).

Putaminal Iron Deposition in HIV Infection
Journal of Neuro-AIDS, 1996T2 shortening (hypointensity) in magnetic resonance (MR) images of the putamen, which may be associated with iron deposition, only occurs in normal subjects over the age of 60 years. Increased or premature putaminal iron deposition may be related to brain injury.

Iron is stored within the liver, spleen, and other organs of the reticuloendothelial system. Iron overload can occur as a result of primary hemochromatosis, cirrhosis, anemia, and multiple transfusions. PET/MR imaging has the ability to use multiple MRI sequences to detect and confirm liver iron deposition.

Iron deposits in the precambrian iron-ore formations
Vestnik of North-Eastern Federal University. Series "Earth Sciences", 2023Аннотация. В статье приводится краткая информация о распространении железорудной формации на континентах, с которой связаны крупнейшие месторождения железных руд. Указывается, что значимым компонентом железистых кварцитов многих месторождений мира, а также сформировавшихся за их счет залежей богатых железных руд других формаций являются благородные ...

Iron Deposition in the Corneal Graft
Archives of Ophthalmology, 1983Linear iron deposits in the corneal epithelium are well-documented phenomena in a variety of circumstances, both normal and pathologic. A characteristic annular pigmented line, appearing clinically as an "iron" line, occurred in the donor epithelium of approximately 13% of corneal grafts with retained sutures. Eight cases of normally functioning grafts

Iron Ore Deposits Associated with Precambrian Iron Formations
Elements, 2011Most large deposits of iron ore are associated with iron formations for the simple reason that they have the highest iron concentrations of any “normal” rock type. Iron formations are found in all Precambrian shields. Iron was preconcentrated in iron formations by surface processes in Precambrian marginal-marine environments, as outlined elsewhere in ...
