Atmospheric inputs of iron to the open ocean are hypothesized to modulate ocean biogeochemistry. This review presents an integration of available observations of atmospheric iron and iron deposition, and also covers bioavailable iron distributions. Methods for estimating temporal variability in ocean deposition over the recent past are reviewed. Desert dust iron is estimated to represent 95% of...
International Journal of Preventive Medicine, Vol 5, No 6, June, 2014 800 DEAR EDITOR, Recently, two articles entitled “Protective role of silymarin (SM) and deferoxamine (DF) against iron dextran‐induced renal iron deposition in male rats,” and “Co‐administration of SM and DF against kidney, liver, and heart iron deposition in male iron overload rat model” were published in International Journ...
An 84-year-old man without any signifi cant past medical history (PMH) was admitted for anemia and weight loss. Th ere was no history of gastrointestinal bleeding or iron supplement use. Physical examination was benign except for pallor. His labs showed: hemoglobin 6.8 (11.0-15.6) g/dL, serum iron 30 (65-175) μg/dL, total iron binding capacity 141 (179-378) μg/dL, ferritin 416 (22-275) ng/dL, a...
BACKGROUND Abnormal iron deposition may cause oxidant-induced damage in various organs. We have previously reported that continuous administration of angiotensin II to rats results in an overt iron deposition in the renal tubular epithelial cells, which may have a role in angiotensin II-induced renal damage. In the present study, we investigated the role of iron in the development of cardiac in...
OBJECTIVES We studied the status of hepatic iron deposition and its relationship with blood iron indices, liver histology, and HFE gene mutations in Korean patients with chronic hepatitis C (CH-C). METHODS 105 patients with CH-C who underwent pretreatment liver biopsy were consecutively enrolled. The hepatic iron deposition, histological activity and fibrosis were assessed by appropriate path...
The increased deposition of iron in gastric mucosa is known as gastric siderosis. It is believed that the only regulated step of the iron metabolism cycle occurs during absorption in the small intestine. Once this system becomes overwhelmed due to either local or widespread iron levels, then iron can be absorbed very quickly by a passive concentration-dependent mechanism. This excess iron is in...
BACKGROUND Iron overload is the main transfusion related side effects in patients with transfusion dependent hemoglobinopathies. Severe iron deposition in tissues leads to organ dysfunction. Many organs can be affected such as heart, liver, and endocrine organs. Cardiac failure and liver fibrosis are the consequent of Iron overload in transfusion dependent hemoglobinopathy. Magnetic Resonance I...
conclusion adrenal iron in β-tm can be reliably measured in 3 tesla mri. the results highlight the absence of correlation between adrenal iron deposition both with serum ferritin and hepatic iron. results among patients, there was no significant correlation between plasma ferritin and adrenal t2*. significant difference was detected among t2* values of adrenals between the patient and control g...
Background Chronic iron deposition is known to occur within reperfused hemorrhagic myocardial infarctions (MIs), and could be a source of prolonged inflammatory activity within MI territories. However, whether the stagnant blood downstream to the permanent occlusion (i.e. in territories of non-reperfused MI) could lead to chronic iron deposition is unknown. In this study, using a controlled can...
Remarkable progress was recently achieved in the studies on molecular regulators of iron metabolism. Among the main regulators, storage iron, iron absorption, erythropoiesis and hepcidin interact in keeping iron homeostasis. Diseases with gene-mutations resulting in iron overload, iron deficiency, and local iron deposition have been introduced in relation to the regulators of storage iron metab...
