Transfusional iron overload in patients with chronic anemias can result in multiple organ failure. Experience in the management of iron overload in patients with myelodysplastic syndromes is limited, as many do not receive chelation therapy due to short-life expectancy and the difficulties associated with the administration of the current reference standard chelator, deferoxamine. There have, h...
Dear Editor-in-Chief, We shortly report our results of combined iron chelation therapy with deferiprone (DFP) and desferrioxamine (DFX) versus chelation therapy with DFP alone, in iron overloaded β-thalassemia patients. Desferrioxamine has been a life saving iron chelator for thousands of patients in the last 40 years. However, less than 10% of the patients requiring iron chelation therapy worl...
Growth of Bacteroides fragilis under anaerobic conditions in the presence of either haemin or protoporphyrin IX was inhibited by the ferrous iron chelator bipyridyl. The ferric-iron chelator desferrioxamine inhibited growth in the presence of protoporphyrin but not haemin, suggesting that even under anaerobic conditions Fe3+ is involved in uptake of non-haem iron, which is required in the absen...
The cells of the green unicellular alga Scenedesmus incrassatulus Böhl, strain R-83 released organic chelators for Fe(III) in inorganic nutrient medium both in iron-deficient and in iron-replete conditions. Iron-deficient cells released chelators capable to bind 11nmol Fe. mg (cell DW)–1.h–1, while the chelators released from iron-sufficient cells after contact with Fe(III) were sufficient to b...
Parabactin, a microbial iron chelator (a siderophore), is shown to be a more potent cell synchronization agent than either desferrioxamine or hydroxyurea. When the L1210 cell cycle is blocked with parabactin, cells are held at the G1-S border. If the ligand is later washed away, the block is reversed, and the cells cascade into S phase. The cells are synchronized through three cell cycles. The ...
Data are presented indicating that the growth of 5 out of 5 murine lymphoid tumors can be inhibited in a synergistic fashion in vitro by combined treatment with the iron chelator deferoxamine (DFO) and an immunoglobulin G (IgG) monoclonal anti-transferrin receptor antibody (ATRA). A two-way doselresponse analysis shows that the ATRA becomes more efficient as an inhibitor with increasing doses o...
background: cadmium (cd) is an extremely toxic metal and environmental exposure to cd has been particularly problematic in the world. oral exposure to cd may result in adverse effects on a number of tissues, the immune system, and the cardiovascular system. compounds containing cd are also carcinogenic. the presence of cd in drinking water resources in the southeastern region of rafsanjan plain...
Two different chelator-based antimicrobial catheter lock solutions, methylene blue-citrate-parabens (MB-CIT) and minocycline-EDTA-25% ethanol (M-EDTA-25% ETOH), were compared in 2-h biofilm eradication experiments. Eradication of both mature and immature Gram-positive, Gram-negative, and fungal biofilms was assessed. M-EDTA-25% ETOH was able to fully eradicate all biofilms within 2 h. MB-CIT wa...
Our previous study showed a reduction in serum ferritin of β-thalassemia patients on hydroxyurea therapy. Here we aimed to evaluate the efficacy of hydroxyurea alone and in combination with most widely used iron chelators like deferiprone and deferasirox for reducing iron from experimentally iron overloaded mice. 70 BALB/c mice received intraperitonial injections of iron-sucrose. The mice were ...
