Carbonyl iron powder (CIP) has been used as a food additive or mineral supplement. However, the effects of CIP on iron deficiency anemia (IDA) and its subchronic toxicity have not been investigated. We found that oral administration of CIP at a dose of 2.96 mg/kg recovered the hemoglobin concentration of erythrocytes of IDA rats to the normal level after 8 days. The no observed adverse effect l...

In this work we present the synthesis and characterization of iron oxide nanoparticles (IONPs), which were structurally and magnetically characterized. The use of iron salts and an organic acid (l-serine or ascorbic acid) as precursors under solvothermal conditions yielded these coated IONPs. The powder X-ray diffraction pattern of FeO-1 and FeO-2 is consistent with hematite (a-Fe2O3) and hemat...

outpatient department because of anal bleeding. She had been diagnosedwith ulcerative proctitis about 1 year previously and had experienced intermittent anal bleeding during treatment at a local clinic. She had no significant medication history and in particular had not used laxatives or oral iron. The initial colonoscopy revealed numerous variable-sized areas of black pigmentation in the mucos...

Optimization of process parameter is one of the ideal goals in laser sintering. The results of this process were measured as output parameters like: density, micro hardening, macro hardening, tension, roughness, stiffness, balling. In this paper, the influence of input parameter such as laser power, scan speed, material powder and etc are surveyed on output parameter like balling affection and ...
