Hexamethylenebisacetamide (HMBA), a potent inducer of differentiation of transformed cells such as murine erythroleukemia cells, causes a prolongation of the G1 phase of the cell cycle during which commitment to terminal differentiation is first detected. Removal of HMBA prior to the G1 phase aborts commitment. To further define the relationship between the G1 phase and commitment to differenti...

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...

Aceruloplasminemia is an autosomal recessive disorder of iron metabolism caused by mutations in the ceruloplasmin gene. Its prevalence is 1 in 2,000,000 people in Japan. This is a disorder of neurodegeneration with iron accumulation in the brain revealed by MRI. The iron overload induces oxidative stress and generation of reactive oxygen species, which triggers a cascade of pathological events ...

Bradykinin relaxes arterioles on the brain's surface. This response is endothelium-dependent. The data presented here confirm the hypothesis that hydroxyl free radical mediates this response and may be the endothelium-dependent relaxing factor for bradykinin in this microvascular bed. The response to a locally applied bolus of bradykinin (80 micrograms/ml) was monitored by intravital TV microsc...

The purpose of this study was to investigate hemoglobin and iron handling after subarachnoid hemorrhage (SAH), examine the relationship between iron and neuroglial cell changes, and determine whether deferoxamine (DFX) can reduce SAH-induced injury. The SAH was induced in Sprague-Dawley rats (n=110) using an endovascular perforation technique. Animals were treated with DFX (100 mg/kg) or vehicl...

Osteoarthritis, also known as degenerative arthritis or degenerative joint disease, is an epidemic disease that affects millions of people worldwide. Despite extensive recent work on the cellular biology of osteoarthritis, the precise mechanisms involved are still poorly understood and there is no effective treatment for this disease. The role of transforming growth factor-beta (TGF-β) in promo...

There are few effective agents that safely remove excess iron from iron-overloaded individuals. Our goal was to evaluate the iron-removing effectiveness of acetaminophen given ip or orally in the gerbil iron-overload model. Male gerbils were divided into 5 groups: saline controls, iron-overloaded controls, iron-overloaded treated with ip acetaminophen, iron-overloaded treated with oral acetamin...

The emergence of new chelators is likely to have a major impact on the treatment of thalassemia major, sickle cell disease and other hematologic disorders for which regular red cell transfusions are required either to correct severe anemia or to prevent major complications of the underlying disease. In comparison with deferoxamine, which requires prolonged parenteral infusion to achieve negativ...

Deferoxamine (DFO), a hydroxamic siderophore with high affinity for Fe(III), is immobilized as functionalized self-assembled monolayer of thiol (SAM) on the gold surface screen-printed cell to develop voltammetric sensor iron(III). The working electrode was characterized, before and after functionalization, by determining properties such area double-layer capacitance. Fe(III) detection performe...
